The machine used for roll slitting is called a slitter rewinder, a slitter or a slitting machine - these names are used interchangeably for the same machines. Roll slitting, also known as log slitting or rewind slitting, is a shearing operation that cuts a large roll of fabric into narrower rolls. The log slitting terminology refers back to the olden days of saw mills when they would minimize logs into smaller sections. They might additionally use these noticed mills to chop iron rods into smaller sections. By today's definition, slitting is a process by which a coil of fabric is lower down into quite a few smaller coils of narrower measure. Potential workpieces are selectively thin (0.001 to 0.215 in.) and can be machined in sheet or roll form. Slitting is taken into account a practical various to other methods attributable to its excessive productiveness and the flexibility of supplies it will possibly manage. Rewind slitting includes rewinding the material via plenty of knives to form narrower rolls of materials.
When the term "slitting machine" is used to describe the machine, the three components are referred to as the unwind, the slitting part and the rewind. Slitter rewinders are usually used to slit plastic films, paper and metal foils. The unwind is often braked to maintain correct pressure in the material. Some machines have a driven unwind which reduces the effect of inertia when beginning to unwind heavy rolls or when the fabric could be very rigidity sensitive. The slitting part has three fundamental options: Rotary shear slitting, Crush cut slitting, and Razor slitting which is ideal for thin plastic film. The rewind part additionally has options. The main kind is centre winding using differential rewind shafts.
Roll slitting is a technique closely used by Converters industry. The converter industry usually refers to companies who print, coat and laminate materials. A typical converter is an organization manufacturing producing flexible packaging material for packaging food. This may increasingly contain purchasing large rolls of plastic movie corresponding to biaxially orientated polypropylene (BOPP) which is then printed to the customer's design and coated with chilly seal adhesive for use on excessive velocity packaging machines. This material is printed and coated in huge, large diameter rolls for max efficiency. The rolls are then slit, using a slitting machine, into smaller rolls of the size for use on the packaging machine.
Capacitors are one of the building blocks of any digital circuit they usually perform an necessary perform of storing and supplying electrical charge when in demand. There are various varieties of capacitors that perform totally different capabilities based on their bodily properties. Tantalum is a form of refractory metallic that is usually used as a small part in an alloy. In the electronic circuits, a SMD tantalum chip capacitor is recognized as a small capacitor that's used for high-frequency ranges. Almost all the current electronic units use this component in their circuitry. Another variant that also performs an vital function in electronic gadgets is a trimmer capacitor that is also used extensively in electronics. Its flexible nature is extremely useful in molding it into a plate or tube form. The gaps between its metalized surfaces are filled with a dielectric.
This type of capacitor covers a wide range of capacitance and the plates in it are either placed in distance from one another or shifted towards one another to alter the amount of capacitance. A dielectric is used for insulation between the plates. This capacitor will get the identify owing to its performance of trimming the active and passive circuits' performance. A metal-oxide Varistor is made up of a mass of metal oxides which might be sandwiched between the electrodes. The boundary between every of the zinc oxide grains form a diode junction that causes current to movement in a single direction. The operate of this amazing device is to prevent a surge in voltage from damaging the circuits.

On the subject of solar power, the one query that most individuals grapple with is the best way to enhance the efficiency and output of their systems. There are two solutions to this problem. One is to increase the number of solar panels one is having and the second methodology is to increase the efficiency of the present panels. The second option largely depends upon the kind of solar mounting rack in place and is far cheaper. It requires the usage of solar rack to increase the panels' exposure to the solar to tap extra solar energy. The standard way of solar mounting has been to use a roof rack the place the panels are raised on the roof for sunlight exposure. Nevertheless, this methodology of solar mounting faces critical challenges when there's the presence of trees and different obstacles as it will restrict the solar exposure.
Solar outdoor lighting system has change into a number one alternative supply of energy in the current where the costs and prices for several sorts of power sources are skyrocketing. It is because the source is totally free from the sun. Most houses are being lit up by this new manner as extra people wealthy and poor look for a strategy to reduce on the large vitality bills. A very good benefit of this supply of power is that it can be used for various functions and though it could cost loads initially to purchase the tools, this expense will later be recouped because the financial savings are big and if one does proper solar mounting they stand to realize even more.
The other various is the usage of floor mounting especially for solar landscape lighting. This type of solar mounting makes use of a pole and solar rack. That is achieved relying on the sunlight's frequency to a sure point. It additionally permits for simple access and maintenance. Additionally it is reasonably priced as one will not be forced to change the roof structure to accommodate the solar panels. The solar rack mounting on the ground also causes little interference with the looks of the home and compound. However when selecting this option one has to consider the security of the place especially the case of vandals.

J•克雷格•文特爾，這位率先完成人類基因組測序，設計出世界首個“人工生命"，被世人成為“科學狂人"的科學家，為我們解釋為什么簡單的 綠藻 類在基因工程技術的協助下，可能成為打開未來之門的鑰匙。
采訪 戴維•別洛(David Biello)
翻譯 趙瑾
為什么研究藻類？
首先看看藻類的潛在產出吧。與現有農業體系的最高產出相比， 綠藻 類的產值還可高出1～2個數量級。假設我們要用液體運輸燃料來取代美國全部的運輸燃料，而燃料的生產以玉米為原料，那將需要3倍于美國陸地面積的生產場地才能達到這個目標。如果以藻類為原料，生產場地則可縮小到美國馬里蘭州的面積。顯然，後者是可行的，而前者則為無稽之談。
長期以來，大家都在自然界中尋找能將世界從能源危機中解救出來的神奇藻類，但經歷了一個多世紀的尋覓後，人們還是未能找到它。我希望我的研究團隊能比前人幸運，因為現有的多種基因工具，為我們提供了一種改寫遺傳密碼的新途徑，使細胞能夠按照我們的指示運作。
我們為什么要這樣做這些研究？
我們生活在同一個星球上。套用一句老話：我們同坐一條船。如果某個人拿起電鑽，在船底鑽個洞，我們全都會完蛋。隨著礦物能源耗盡，石油和煤礦工業遲早衰落，這是不可避免的。現在，那些具有前瞻性的能源公司正試圖轉向再生能源的生產。這些解決方案絕非拿起書本就能找到，而是需要長期的研究。
目前的主要障礙是什么？
首先是經費──我們還需要10多億美元的設備，其實是培育出一種真正耐用，可用於工業生產的藻類，這樣才有商用基礎。衹要能培育一種細胞，能源產出量是現在的10～100倍，那一切都會不同。
養殖藻類需要什么養料？
除了轉化和提煉設備外，我們所需的三種主要原料是：二氧化碳、陽光和海水。我們正在全球各地尋找這三種資源都很充足的地方。
將此設想付諸實施，妳認為需要多少年的時間？
對於我們來說，這是一個長期計划，或許是10年。我們不會承諾在未來一兩年內，就能為妳的車提供新燃料。
人類基因組測序與藻類燃料的研發相比，哪個項目更具挑戰性？
完成人類基因組測序我用了9個月。但在藻類細胞及其生產體系中，各種待測參數多達500種。毫無疑問，藻類燃料的研發，具有更大的挑戰性。同時，如果我們成功的話，對世界的影響也將更加深遠。
藻類研究經歷過很多挫折，是什么讓妳保持了成功的信心？
我喜歡用數據說話。有些人喜歡說大話，那他們就有義務拿出令人信服的數據，證明他們說的話是可靠的。目前，在藻類燃料這個研究領域，還沒有任何人掌握了這樣的數據。不過，最新的一些研究方法，會有助於我們解決那些以前無法回答的問題。既然歷史已經告訴，藻類是個難搞的家伙，那我們也不可能保證一定會成功。

Donatella Madrigal 白天是個平面設計師，替客戶設計廣告，但通常都只在電腦上作業。到了晚上，她便棄數位就類比，到 「The Arm Letterpress」租用手動印刷機印製她自己設計的卡片，一次通常印個幾百張賀卡，拿到網路上去賣，價格是一張 5 美元。
人們似乎正回歸那些具有藝術質感的手作產品，商品網站《Etsy》於 4 月初刊出超過 2.2 萬件凸版印刷品，這數字是 1 年前的 3 倍以上。
據《彭博社》報導，過去 10 年來，凸版印刷業者繁榮興旺，全拜平面設計工作者所賜，數位化是他們的工作方式，但業餘時間他們都在尋找另一種可能性。
「The Arm Letterpress」是由曾祖父是印刷工的 Dan Morris 成立的，Morris 在澳洲念完藝術與建築後，到美國馬里蘭州的巴爾的摩市的一家印刷廠當學徒。他在 14 年前以 285 美元買下一台 Vandercook 印刷機，號稱印刷機中的凱迪拉克，如今一台要價 1 萬美元。
19 世紀末，凸版印刷開始走下坡，因為整行式排字機讓印刷工可以快速排版。1890 年代早期，全美只剩下 1 家鉛字製造商。凸版印刷一路苦撐到膠版印刷術的出現。
但現在，有個名叫 《Ladies of Letterpress》的網路集團，有將近 1500 個會員，其中包括 50 位男性，他們辦在週末的年會工作坊吸引了超過 100 人參加。
文具雜誌《tationery Trends》編輯 Sarah Schwartz 說，這樣的趨勢顯示人們正回歸那些具有藝術質感的手作產品。
最明顯的一件事情是，凸版印刷業者傳統上會避免紙上出現壓痕，在他們的行話裡這叫做「拳印」，他們喜歡的是類似雷射印表機所處理的紙面，還把那種平順感以「吻痕」來形容。但現在「拳印」正是最受喜愛的效果。
2008 年金融海嘯之下，奢侈品市場萎縮，只有凸版印刷品市場力挽狂瀾。
一家位於紐約曼哈頓的高檔文具店 Kate's Paperie 表示，2011 年凸版 快速印刷 品銷售量從 2010 年的 33% 上漲到 44%。
手作商品網站《Etsy》於 4 月初刊出超過 2.2 萬件凸版印刷品，這數字是 1 年前的 3 倍以上。
Kimberly Austin 在 8 年前花了 750 美元買下了她的第一台手動印刷機，成立了 Austin Press 這家一人 快速印刷 廠，印製賀卡、感謝卡和婚禮請帖，然後在自己的網站以及連鎖女性服飾店 Anthropologie 裡頭賣，
她表示去年的銷售額大約是 25 萬美金，大約比 3 年前成長了 2 倍。
Zoe Feldman 則是每隔幾週就會到 The Arm 租一些時段印製卡片，放在《Etsy》上面賣，他的卡片主題常是 1990 年的電視節目中的諷刺對白，另外他製作同性婚姻者專用的母親節與父親節卡片。
Zoe 同時也是百事可樂 (Pepsi)( ) 的前任主管，目前在紐約大學商學院念 MBA，她說如果目前的卡片生意發展的好，有可能會放棄正職工作。

十五輛設備周全的「尚搭心」公車昨天上路，開啟台南大眾運輸的新紀元。台南市長賴清德說，為發展大眾運輸系統，市府持續汰換公車，建置智慧手機APP動態查詢系統，引進低地板和無障礙設施公車，車窗更貼上高效 3M隔熱紙 ，實在「搭心」。他還將全力爭取中央支持，進一步建構「捷運化的大眾運輸系統」。
台南市交通局昨天舉辦「台南市十五輛大客車啟用典禮暨EBUS智慧手機APP宣傳」記者會，由賴清德與交通局長張政源向市民推介新公車。
賴清德表示，「尚搭心」公車上路，大家將可透過手機APP動態查詢公車，或從LED站牌得到即時資訊。為提升行車安全，司機將穿著反光背心，車身也貼上反光識別材料。為阻隔紫外線，讓乘客免曬太陽，特貼上強效 3M隔熱紙 ，兼具減少油耗、節能減碳效果。
賴清德並強調，為提升搭車舒適度、確保行車安全，台南公車正積極汰舊換新，繼去年增加五輛低地板公車、今年增加十五輛，還預計在一百零四年底汰換一百九十一輛舊車，高雄客運車齡降低為六年，興南與新營客運車齡降為八年。
他進一步指出，台南升格直轄市有四項基本工作，除治水、土地通盤檢討、振興工業區，最重要的是建立捷運化的大眾運輸系統。他日前參加行政院會，即嚴正指出南市不要求像新北市高達一千九百多億的捷運補助，只要中央給台南三百億或五百億，市府就可因地制宜，規劃完善的捷運化大眾運輸系統，以完善路網吸引市民轉乘，充分利用大眾運輸系統。

The compact size and versatility of skid steer loaders make them a typical instrument on construction sites, landscaping jobs and farms. Nonetheless, failing to follow certain fundamental safety guidelines when working a loader can result in serious damage or demise
The operator should always put on a seat belt and use an interlock management, corresponding to a restraint bar, if the skid steer loader has one. Many loaders will not operate until the interlock system or seat belt is secured.
Enter the skid steer loader only when the bucket or other attachment is resting on the ground, or when raise-arm supports are in place. Don't use foot or hand controls to aid in getting into or exiting the loader. By no means exit the loader unless the bucket has been lowered to the ground, the parking brake set and the engine turned off.
By no means overload the machine, as uneven distribution of weight might trigger it to tip over. Concentrate on your environment and keep all parts of your physique contained in the cab whereas the loader is running.
Keep the foot pedals on the skid steer loader away from all kinds of debris, akin to dirt and ice. Don't modify the operator's cabin or take away the outside screens.
Never work on the loader while the engine is running. All the time service the loader whereas the bucket is on the ground. If this is not attainable, have carry-arm supports in place.
