IPC: B24B11/08
Filed: 1971-05-10
Abstract: 1288895 Lapping ball bearings F STEINMETZ 10 May 1971 13969/71 Heading B3D A machine for lapping ball bearings comprises an inner member 10 having an outer frustoconical surface disposed within an outer member 18 having an inner frusto-conical surface, the members having their axes disposed in a vertical direction, one of the members having at least one spiral groove 33 in its surface, power means for rotating one of the members, and means for introducing ball bearings between the surfaces of the members. In one embodiment, the spiral groove 33 is formed on the outer .surface of the inner member which is supported by a shaft (12, Fig. 2, not shown) driven by a gear transmission (13) from a motor (12). The outer member is supported by brackets spaced around its circumference and connected to fluid pressure piston-and-cylinder devices which are operative to raise the outer member when desired. An element 32 may be secured to the outer member 18 to apply a lapping pressure or the devices may be double acting so as to lift the outer member or apply a lapping pressure by urging it downwardly. A lapping material or liquid may be supported to the space between the members from a nozzle 38. A receptacle 35 with a spout 36 feeds the ball bearings to the upper end of the inner member 10, centrifugal force caused by rotation of the member acting to urge the ball bearings so that they enter the spiral groove. At the lower end of the member, the ball bearings fall into a trough 34 which conveys them to an elevator 37 for transport to the receptacle for a further lapping operation. In another embodiment, the spiral groove is formed on the inner surface of the outer member.

Title: Air conditioning systems and the like
IPC: F24F3/052
Filed: 1970-10-15
Abstract: 1316308 Air conditioning HONEYWELL Inc 15 Oct 1970 49119/70 Heading F4V [Also in Division G3] In an air-conditioning system for a number of separate zones 11-13, air is supplied through heat exchanger 24 and blower 17 and entry into zones 11-13 is controlled by dampers 21 operated by respective pneumatic thermostats 14 providing 0-16 p.s.i. signals to motors 22. The thermostat signals are also transmitted to selector 28 which admits the weakest signal, i.e. that corresponding to the zone of lowest temperature, to a relay 27 (Figs. 3 and.4) controlling supply of heating fluid to heat exchanger 24 via a valve 26 biased to an open condition. When the signal fed to relay 27 is below 3 p.s.i., the relay provides a falling output pressure at 30 thereby allowing valve 26 to increase flow to the heat exchanger. With signals between 3 and 4 p.s.i., the output at 30 remains constant, and with signals above 4 p.s.i. the output increases, thereby causing valve 26 to decrease flow to the heat exchange. In a modification, each zone connects additionally with a. cooled air supply controlled by further dampers (83) which are operated by the same thermostat as the corresponding warm air damper. A selector (88) similar to selector 28 admits the weakest signal to relay 27 as above, but also admits the strongest signal, i.e. that corresponding to the zone of highest temperature, via inverting relay (90), i.e. one providing 16-0 p.s.i., to a relay (92) corresponding to relay 27, and relay (92) controls the flow of cooling medium via valve (86) to cooler (84) in the cooled air supply duct. Valve (86) is controlled similarly to valve 26 above but the critical pressure range about which the cooling system cycles is 12-13 p.s.i. as opposed to 3-4 p.s.i. for the heating system.
