Abstract: A bearing having a full complement of balls is described wherein an outer ring is made of a wrought heat-resistant alloy and provided with a depth-of-track to ball-diameter ratio of at least 1 : 10. Cobalt base and nickel base alloys or a combination thereof have been found to be particularly useful with this type of bearing. A method of making the bearing includes preassembling a bearing structure by placing a thermally expanded conical outer ring over an assembly comprising an inner ring and a full complement of balls within the inner ring face. Subsequently, the conical outer ring is compressed to bring a tapered portion thereof towards the balls and produce the desired depth-of-track to ball-diameter ratio with final radial clearance and fit. A particular selection of component parameters is described for the manufacture of the device.

Abstract: An electrical contact surface is prepared by forming a thin nickel or cobalt plate over a conductive substrate, coating the nickel plate with a thin silver plate, and thereafter coating the silver surface with mercury and causing the mercury to amalgamate into the lower nickel and silver plates. The silver layer may be further coated with a layer of gold or a layer of one or more of the platinum group family metals before the application of the mercury surface. Cadmium may be applied over the mercury layer before amalgamating the mercury into the silver layer.

Abstract: AN ELECTRICAL CONNECTOR ARRANGEMENT FOR INTERCONNECTING AN ARRAY OF SOLAR CELLS INCLUDES AN ELONGATED, FLEXIBLE STRIP FORMED WITH LATERALLY PROJECTING TABS ATTACHED TO ADJACENT ROWS OF SOLAR CELLS. THE TABS ARE DIMENSIONED AND ATTACHED SO AS TO PRESERVE ELECTRICAL CONTINUITY BETWEEN VARIOUS CELLS IN THE EVENT THAT CELL CRACKING OCCURS THAT OTHERWISE WOULD DISRUPT ELECTRICAL CONTINUITY. THE FLEXIBLE STRIP INCORPORATES SHORT TABS PROJECTING FROM ONE SIDE FOR CONNECTION WITH A TOP ELECTRODE OF ONE CELL AND AT LEAST ONE EXTENDED TAB LATERALLY PROJECTING FROM THE OTHER STRIP SIDE FOR CONNECTION WITH THE BOTTOM ELECTRODE OF AN ADJACENT CELL. THE EXTENDED TAB BRIDGES ACROSS THE MAJOR PORTION OF THE BOTTOM OF THE ADJACENT CELL AND IS CONNECTED THERETO ONLY AT POINTS BEYOND THE MIDPOINT OF THE ADJACENT CELL. CRACKS SPLITTING THE CELL IN HALF ARE THEN PREVENTED FROM COMPLETELY INCAPACITATING THE SOLAR CELL.

Abstract: A fuel tank for internal combustion engines used on hand-held tools comprises a rigid container associated with the crank case of the internal combustion engine and a flexible bladder disposed within the rigid container. Fuel inlet and outlet ports are provided in the bladder. The rigid container has an air inlet port which presents the outside surface of the bladder with filtered air of the carburetor air intake chamber. As fuel is withdrawn from the bladder by the engine, the bladder collapses around the remaining body of fuel preventing the creation of a vacuum and thus eliminating the need for a fuel tank vent.
