Abstract: An energy system of the type having a galvanic cell which is supported within a receptacle for contact with an electrolyte within the receptacle. The galvanic cell includes a solid metal core, a porous electrode having a positive charge with respect to the core, and a porous separator layer disposed between and separating the core from the electrode to enable the flow of electrolyte therebetween. The electrode and separator layer are disposed about the core and the core is of a flat configuration having a large surface area as compared to its thickness so as to provide a high power output per unit of volume of the core. The electrode and separator layer are of a multi-layer construction being made of sheet material and wrapped about the core to enable control of the surface area of the electrode and the thickness of the separator layer whereby the power output and operating life of the cell may be controlled.

Abstract: The present invention relates to a wire stripping device. A pair of jaws mount a first pair of cutting blades for movement towards each other substantially in a plane to cut insulation. A yoke with spring arms mounts a second pair of cutting blades at right angles to the first blades for movement towards each other substantially in the same plane as the first blades as well as for movement axially when an adjustable stop is reached. A first handle, through linkage, moves the jaws, and the jaws by cam ears move the yoke arms whereby all the blades are caused to move towards a central axis during the insulation cutting action. The second handle connected by a push bar to the yoke moves the yoke axially to separate the first and second blade means when a spring bias is overcome when the stop is reached.

Abstract: A method and apparatus for producing a plurality of web units, such as business forms, on a single machine. A plurality of paper webs are simultaneously processed while they are moving through the machine in superposed relationship and in a direction which is common to all of them. The webs are then separated, and their direction of movement is changed to one which is normal to the direction of movement through the machine. The webs are further processed after the direction of movement has been changed as by cross-perforating and folding and by forming them into separate stacks at the front of the machine.
