The invention relates to a regulating arrangement in particular on packing machines for the feed of weblike packing material in register with decorations or folding indications, so-called crease lines, present on the web. In accordance with the invention the desired control is obtained by regulating the tension of the web with the help of a guide roller over which the web is passed. The speed of t...

A cladding process is disclosed wherein hard carbide cutter inserts, as well as polycrystalline diamond composites, are metallurgically bonded ininto an interior core of a drag bit body. The cladding is bonded onto the exterior surface of the core of the drag bit by a powder metallurgy process. A thin layer or coating of a suitable metal, preferably nickel, is provided on, for example, the carbide...

A method of preventing the yellowing of the outermost coating of a multicoat coating system is disclosed. The method comprises initially depositing onto a conductive substrate by cathodic electrodeposition a primer coating comprising at least one layer of an amine-epoxy resin adduct and a cross-linking agent, and then curing said primer to a hard, durable film. Then, depositing a second coating on...

An array processing system including a plurality of processing elements each including a processor and an associated memory module, the system further including a router network over which each processing element can transfer messages to other random processing elements, a mechanism by which a processor can transmit data to one of four nearest-neighbor processors. In addition, the processing eleme...

A method of tinting soft contact lenses (L) uses at least one transfer-pad printer (2) including a suitable ink of the desired tint, and at least one printing block (6) carrying an iris pattern. The contact lenses are attached to lens mounts (14), preferably by being shrunk onto curved heads (18) of the mounts, and are then aligned, in turn, with the pad (4) of the transfer-pad printer (2). For ea...
