Abstract: The invention relates to polygonal flank sockets, or drives, for correspondingly shaped fasteners which impart the torque turning load thereto, and more particularly relates to sockets and socket drives adapted to accommodate nut type fasteners that are complements thereof, of improved construction to more effectively sustain nut turning loads. The present arrangement insures surface-to-surface flat engaging contact between the splines and flanks of the nut fasteners for any purpose requiring torque or turning loads. In the present invention, straight surface-to-surface contact for load transmitting action is assured, whereby greater torque loads can be transmitted with the wrench socket embodying the teachings of the present invention.
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 miniature golf apparatus has a variable putting surface with a hole and sunken lights disposed adjacent each end. Consoles at each end provide for random selection of the putting surface contour and the illumination of lights to locate the commencement of putts to the hole at the opposite end of the device. To vary the putting surface, additional alternate manual selection is also provided. A pair of rotatably driven beams have a plurality of cross bars of different lengths resiliently and pivotally attached to extensions of the beams. The putting surface is disposed on clip members carried by the bars. Independent rotation of the beams provide lengthwise undulations and widthwise slant of the putting surface. Crank arms and motors carried by some of the bars flex the bars to give a curvature to the putting surface.
Abstract: The present invention provides a brush-like mounting device of the type for detachably mounting a cleaning, stripping, scrubbing, polishing or the like type member, such as a pad, for commercial, industrial and/or residential applications. The device includes a generally rigid body member having at least one generally planar side surface. First retention means, including resilient filament means, extends from this surface for coacting gripping engagement with a pad; and second retention means including resilient filament means extends from said surface and angularly in respect to said first retention means for coacting gripping engagement with the confronting surface of said pad and with said first and second filament means coacting for detachably mounting said pad on said mounting device.
Abstract: The present invention relates to an apparatus and method for making a flexible duct of wire-reinforced construction made from a plurality of adhesive-coated polymeric tapes. The tapes are simultaneously applied from angularly oppositely disposed directions in conjunction with application of a reinforcement wire to provide a helix construction with overlapping convoluted edges to provide a duct of predetermined length.

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.
