  • Rotary Cylindrical Device With Coupled Pairs of Pistons
    Publication number: 20100236522
    Abstract: This invention is a cylindrical rotary power device, usable as and convertible to a rotary internal combustion engine, pump, and/or compressor. The device incorporates an ingenious design and composition utilizing bilateral symmetry to minimize power losses and maximize efficiency. It operates with a minimum of moving parts which can be manufactured at relatively low cost and readily maintained. Also, the power device of the present invention is readily converted to an internal combustion engine by merely removing the external power source and providing fuel flow and ignition charge to the cylinders.

  • Anode structure for a plating cell
    Patent number: 4493758
    Abstract: A plating cell for plating edge connector tabs of printed circuit boards comprises a pair of anode structures 119, each of which has a pair of elongate anodic platinized titanium plates 131 spaced apart by an anode divider 150. Castellations in the anode structures give rise to holes 132 through which electrolyte can flow. By means of this configuration of the anode structures an even deposit of plated metal may be obtained.
