Title: Improvements in or relating to apparatus suitable for use as a rotary pump, engine, air compressor or motor, windmill, drill, meter, blower, vacuum pump or the like
IPC: F01C5/00
Filed: 1924-11-27
Abstract: 249,587. Feuerheerd, E., Shishkoff, P., and Hallewell, F. W. Nov. 27, 1924. No Patent granted (Sealing fee not paid). Fixed-abutment type.-Apparatus for use as a rotary engine, pump, motor or the like has flexible vanes 10 - - 13 attached by their outer ends to a rotary liner 6, and by their inner ends to a sleeve 5 on a shaft 4 disposed eccentrically with respect to the liner; the connections of the vanes are such as to permit slight angular movement of each vane round its points of connection in order to limit the stress when the vanes are flexed. The ends of the vanes have strips 14 with cylindrical ends in grooves in the liner and sleeve; the vanes may be composed of one or more strips of spring steel or other suitable material, the pockets formed by them may be encased in leather or may contain a flexible bag. The casing has an inlet 2 and outlet 3 with which the pockets communicate through the ports 7 in the liner. Either the liner or the shaft may be rotated by external means. In the modification for a pump shown in Fig. 3, the vanes are arranged approximately tangentially to the sleeve 5 and protuberances 15 are disposed on the liner between the vanes. The rear faces 16 of the protuberances are curved and the following vane closely fits into each curve as the vane becomes fully flexed. The faces 17 are shaped oppositely to the faces 16 so that horns 18 are formed which support the vanes in their fully extended position. The fluid passes from the inlet to the ports 20<a>, then through the rotor and the ports in the liner to the discharge outlet. These pumps may be arranged in pairs in a casing provided with cooling fluid. In another modification protuberances are formed on the sleeve 5, the leading face of each supporting a vane when it is extended and the rear face supporting the following vane when it is flexed. The ends of the spindle 4 carrying the sleeve 5 may be mounted in discs in the side plates of the casing. Rotation of these discs by the lever 33, Fig. 7, varies the eccentricity of the apparatus.

Auxiliary-actuating gear; lever-actuated pumps; screm-actuated pumps; air-vessels; relief -devices; single-acting, suction-valveless piston pumps; suction reservoirs; valves, arrangement of.-In a lubricating- apparatus of the kind described in the parent Specification, the lubricant passes from the reservoir 1 through ports 35 into the pump chamber 3, and is forced through the delivery valve 19 to the delivery pipe 24 by a hand-operated plunger 13 provided with a screw 45 engaging a nut 44 on the head of the reservoir. A piston 5 slides on the plunger rod 4 and descends in the lubricant until stopped by a pin 53. Recesses 54 in the rod prevent suction action on the lower face of the piston 5 when the latter reaches the pin 53. In another form, the chamber 3 and plunger 13 are arranged across the end of the reservoir 1, the plunger is operated by a hand lever, the delivery chamber 18 communicates with a relief valve chamber opening into the reservoir, and the piston 5 has an aperture closed by a valve which is opened by a chain anchored to the end of the reservoir when the piston reaches the limit of its movement. In another form, the chamber 18 delivers into a chamber containing a spring- pressed piston and communicating with the delivery pipe. In another form, the plunger rod 4 engages the screw 45 by means of a key so that it may be operated directly by hand. The delivery valve 19 may have a recess in its surface fitted with a packing ring 22.

In Fig. 1 the supply to an electric oven heater M1 is controlled by contacts D of a relay B which is operated intermittently by virtue of contacts C of a bimetallic switch, the bimetallic strip A of which is associated with a heater AH connected in parallel with relay winding B. The on/off time ratio is controlled by the position, of a stop El against which strip A bears. Bending of strip A due to heating causes a strip F to pivot about P1 and open contacts C. Strip F is also bimetallic to provide ambient temperature compensation. The position of stop E 1 is automatically varied through a bell-crank lever L by a bellows Y communicating with a fluid-expansion bulb M2 in the oven so that the on/off ratio is reduced as the oven temperature rises. A modified form of lever operating stop E1 is described with reference to Fig. 3 (not shown).

Abstract: 1,182,404. Automatic exchange systems. SIEMENS A.G. 19 June, 1968 [20 June, 1967; 18 Aug., 1967; 24 April, 1968], No. 29112/68. Heading H4K. Connections between subscribers and relay sets across a switching network are set up by direction from a programme controlled device which is relieved of the burden of decision when a fast response is required. A calling subscriber is initially connected to a dialling relay set which may count loop disconnect impulses and forward each digit to the programme controlled device. When sufficient routing digits have been received, the decision to transfer a connection from a dialling relay set to a speech relay set in the wanted direction is taken by the dialling relay set during an interdigital pause. A relay set put into service for an incoming call effects disconnection of ringing on reply without recourse to the programme controlled device. Discrimination between supervisory signals requiring a fast response, and those requiring a slower response that can be referred to the programme controlled device, can be effected in fast acting circuits serving groups of relay sets. Such circuits may handle the connection of registers for the reception of multifrequency codes and associated signals from pushbutton senders, may determine the point at which a subscriber is transferred from a dialling relay set to an outgoing relay set, and may effect the disconnection of ringing tone for an incoming connection. The programme controlled device or the fast acting relay group circuits may refer special service tasks to a special service processor handling such tasks as providing conversions of abbreviated dialling codes, conversions of subscriber addresses, call charge rate computation and storing, and administrative functions in general.
