    Abstract: An asymmetrical or relieved piston is provided in a fluid motor or a pump. The piston is rigidly connected to one end of the connecting rod, the opposite end of which is pivotally connected to a rotating crankshaft. The piston has a relieved upper and lower section each of which has a partial spherical surface. When the piston is tilted in one direction through half of a rotation of the crankshaft, a seal is formed between the partial spherical surface and the wall of a cylinder. During the other half of the rotation, the relieved piston is tilted in the opposite direction, the seal is broken, and fluid bypasses the piston from the upper half of the cylinder volume to the lower half or vice versa. A floating poppet valve is utilized in the engine, and a floating check valve is utilized in the pump of the described single piston embodiments. A pump with no check valve but including two horizontally opposed relieved pistons is disclosed in which one piston is sealed while the other is bypassed, providing nearly continuous pumping of fluid during each rotation of the crankshaft.

    Abstract: The method of contemporaneously sealing interfaces of bearing surfaces for valve faces and cylinder linings in a steel rotary cylindrical barrel having a plurality of longitudinal bores extending through the barrel longitudinally from one end to the other, each of the bores having a restricted diameter intermediate portion connecting a valve surface area at one end of the barrel with a cylinder area extending to the other end. An insert of bearing material is placed in both ends of the bore and a cap secured over a lower end adjoining the cylinder bore. A removable carbon hot top is placed over the other end of the barrel. The barrel and its assembly is heated in a metallurgical furnace for 90 minutes at 1925.degree. F., disposed vertically, with the cap at the bottom and is then removed from the furnace and cooled with the cap resting on a bronze pedestal to cause the bearing material to slowly solidify from the bottom up, and to cause gases to rise through the restricted area of the bore as the barrel cools. When the temperature is below 1000.degree. F., the hot top is removed to permit solidification of the bearing material in the upper valve area.

    Abstract: An easy-to-assemble compressor having a pair of parallel, double-headed pistons reciprocably mounted in respective cylinder chambers in a compressor housing. The pistons are mounted on a crankshaft via Scotch-yoke-type sliders slidably engaged in the respective pistons for reciprocating movement in a direction normal to the piston axis. The sliders convert the rotation of the crankshaft into linear reciprocation of the pistons. The dimensions of these sliders are determined in relation to the other parts of the compressor so that, during the assemblage of the compressor, the sliders may be mounted in position by being passed over the opposite end portions of the crankshaft following the mounting of the pistons and crankshaft within the housing.

    Abstract: 1,134,883. Dry shavers. GILLETTE CO. 24 Nov., 1965 [24 Nov., 1964], No. 49996/65. Heading B4B. [Also in Division C7] A shearing foil for a dry shaver comprises a perforated base sheet 3 1 electrolytically coated with harder material 4 1 which provides sharp cutting edges 5 1 but leaves uncoated that side of the base sheet which will face a blade of the shaver. Fig. 1 (not shown) illustrates making a foil base sheet (3) by electrolytically depositing resilient material, e.g. Ni, on to a metal die (1) having an insulating layer (2) with a configuration corresponding with that of the holes to be produced in the foil. A layer of harder material (4), e.g. of Cr, Rh or hard Ni, is electrolytically deposited on the base sheet (3) while still on the die. Prior to this deposition of harder material, portions of the base sheet may be masked with varnish. The base sheet (3) and harder material (4) may both be electrolytically deposited from a bath of the same composition but using different current densities. During use the shaver cutter causes the foil to wear, the less hard material wearing more than the harder material as illustrated in Fig. 3 (not shown).
