Title: Low speed high torque rotary hydraulic motor
IPC: F01C1/344
Filed: 1971-10-13
Abstract: 1332951 Rotary hydraulic motors M D'AMATO 13 Oct 1971 [4 Nov 1970] 47702/71 Heading F1F An hydraulic motor comprises a rotor 18 having on each end face 18r, 18f an annular groove 42 intersected by a plurality of radial grooves 30, a plurality of angularly spaced abutment members 44a, 44b, ... mounted on stator end plates 16r, 16f and positioned in each annular groove 42, and pistons or vanes 34a, 34b, .... reciprocable one in each radial groove 30 from inner positions (see piston 34a) in which they do not foul the abutment members to outer positions (see piston 34c) in which they extend across their groove 42 and define with one of the abutment members an arcuate working chamber. The working chambers are filled and emptied through axial ducts 40 in the pistons, the inner ends of the radial grooves 30 being alternately filled and emptied through sequential communication with a ring of alternating inlet and outlet ports 70a, 72a, 70b, 72b... in the stator end plates. Thus in Fig.3 the groove 30 containing the piston 34b is in communication with the inlet port 70a. Accordingly pressurized liquid flows through the passage 40 and an L- shaped stator recess 64a into the annular groove 42 between the piston 34c and the abutment member 44a, thereby to cause rotation of the rotor. Simultaneously liquid in the groove 42 on the other side of the piston 34c exhausts through the piston 34d and the port 72a. Each piston has a recess which receives a ball 38 seating in an undulating cam track 36 in the respective end plate 16f, 16r. The shape of the track 36 is such that as the rotor rotates the pistons reciprocate without fouling the stationary abutment members 44a,44b,... A casing 6, 8, 10 encloses the end plates 16r, 16f which are provided with identical pressure pads 74 facing the casing to provide axial force balance. The pressure pads 74 are arranged in two sets, one set being connected by passages (80) to high pressure and the other by passages 82 to low pressure. Each pad 74 is in communication with one of the inlet or outlet ports 70a, 72a... The cover 6 of the casing may be replaced by one which causes only certain of the arcuate chambers to be pressurized, thereby to alter the motor's torque and speed.

Abstract: 1,215,403. Spinneret for conjugate filaments. KANEGAFUCHI BOSEKI K.K. and SNIA VISCOSA NAZIONALE INDUSTRIA APPLICAZIONI VISCOSA S.p.A. 26 Feb., 1968 [25 Feb., 1967 (3)], No. 47709/69. Divided out of 1,215,402. Heading B5B. In a spinneret for making conjugate filaments, part of a liquefied polymer B, Fig. 1, flows via channels 3 and 7 into space 8 where it embraces cores of liquefied polymer A extruded through external injecting passages 9. A second part of polymer B is extruded through internal injecting passages 10 to flow centrally between the extruded cores. These cores of polymer A, entirely surrounded by polymer B, are fed into conduits 13 and spun through orifices 14. The resulting conjugate filaments have cores whose disposition and cross-sectional shape is governed by the passages 9. Thus the passages 9a, Fig. 2A, will provide cores disposed within the conjugate filament as shown in Fig. 5. Alternatively, the cores may have a triangular cross-section, or may be replaced by a single annular core. In an example a highly elastic aromatic polyester forms cores which are surrounded by a polyamide.

Abstract: 1463605 Offshore structures CHEVRON RESEARCH CO 15 Nov 1974 [21 Dec 1973] 49618/74 Heading E1H To reduce the stresses caused by wave motion in the main support legs 56 of a jack up platform 50 as they are first grounded or first lifted from the sea bottom at a particular location, the platform 50 has auxiliary semi submersible support legs 57 which are extendable and retractable by jacking and or ballasting and when extended lift the platform hull above the waves and thereby lessen their consequent induced motion. To locate the platform, the legs 56 are lowered to a position above the bottom and the legs 57 are lowered and locked in position prior to deballasting so that they lift the platform above the waves. The legs 56 are then lowered into a bottom engaging position and the legs 57 fully retracted, the platform hull then being jacked up on the legs 56 to its final position. When retracted the legs 57 may be ballasted to increase the platform's weight and facilitate penetration of the legs 56 into the sea bottom. The operation is reversed to remove the platform and if a force greater than that provided by the legs 57 is required to move the legs 56 out of the sea bottom, the platform hull can be lowered on the legs 57 to the water to increase the upward buoyancy forces. The legs 57 may also be used to support the platform in the event of an emergency e.g. failure of one of the main legs 56. The platform may be self propelled.

Abstract: 1400039 Automatic circuit-breakers TOKYO SHIBAURA ELECTRIC CO Ltd 27 Oct 1972 49674/72 Heading H1N A circuit breaker is tripped by a bimetallic member (55, Fig. 1, not shown) or by an electromagnetic tripping device comprising a magnetic member which surrounds a load current conductor 27 and provides two magnetic circuits 60, 61 each containing an air gap between a respective pair of polepieces 62, 63 and 64, 65, and an armature 66 disposed between the magnetic circuits and adjustable to determine the current at which tripling occurs. As shown the gap between the pole pieces 62, 63 of the main magnetic circuit 60 is disposed at an angle to the gap between the polepieces 64, 65 of the auxiliary magnetic circuit 61. The armature 66 is normally biased towards the polepieces 64, 65 by a spring 71 and the flux produced by the auxiliary magnetic circuit 61. When the current reaches a predetermined level, the force due to the flux in the main magnetic circuit 60 becomes sufficient to overcome that due to the auxiliary circuit 61 and the spring 71 causing the armature 66 to move a rod 67 downwardly so that a member 73 operates a latch 53 to trip the circuit-breaker. The rod 67 to which the armature 66-is secured, may be turned about its axis to vary the gaps between the armature and the auxiliary polepieces 64, 65 to determine the current setting. The armature 66 may be a rectangular bar or a disc with bevelled or cut-away portions. Adjusting screws may be provided in the pole pieces 64, 65 to set the initial position of the armature or spacers 70 may be used together with an insulating washer 69. The bimetallic strip acts on an adjusting screw (54, Fig. 1, not shown), in the latch when sufficiently heated by conductor 27.

Filed: 1964-12-07
Abstract: 1,060,999. Controlling reactors. UNITED STATES ATOMIC ENERGY COMMISSION. Dec. 7, 1964 [May 20, 1964], No. 49782/64. Heading G6C. In a sodium cooler fast breeder reactor, a negative coolant density coefficient of reactivity is effected by an annular void zone in the core. The zone is between the outer annular breeder region and the central fuel region. The latter contains both fertile and fissile materials, which are distributed so as to cause uniform power production across the core cross-section. A loss of coolant or a reduction in its density, causes an increase in the neutron leakage flow from the central fuel to the surrounding outer breeder region. Owing to the relative sizes of the fuel and breeder regions the probability of an equal neutron return flow is less and the reactivity falls. The sodium flows upwards through the core which is composed of vertical hexagonal tubes which enclose the fertile and fissile rods. Uranium dioxide, uranium carbide and plutonium carbide are used; the fissile and fertile materials being plutonium and U238 respectively. Helium gas is used to fill the void zone.
