Title: Synchronous capacitors
IPC: H02K55/04
Filed: 1974-05-30
Abstract: 1445483 Synchronous machines FIZIKOENERGETICH INST AKAD NAUK LATVI SSR 30 May 1974 23953/74 Heading H2A A synchronous capacitor comprises main armature and field windings of superconducting material, a generator for exciting the field winding and a starting motor housed within a cryostat, the generator rotor field winding and starter motor rotor being mounted on a common shaft in a sealed housing within the cryostat. The synchronous capacitor has a starting motor 11 comprising a squirrel cage rotor 16 of superconducting windings mounted on shaft 3. This also carries a superconducting rotor 12 of a generator 10 whose output is supplied over superconducting leads 72 directly to the main field winding 6, also superconducting, of the capacitor and which is also mounted on the shaft. The shaft is carried in bearing 8, 9 in end plates 21, 72 of a sealed housing 25, 20, 19. The housing parts are mounted together using sealing rings to ensure fluid-tightness against the liquid helium filling the cryostat. The fluidtight housing contains gaseous helium as a cooling medium. The main armature winding 4 and the starting motor stator winding are both superconducting and are immersed in the liquid helium filling the inside of the inner cryostat vessel 38, made of an upper portion 57 and a lower portion 58 bolted together. The synchronous capacitor is surrounded by a shield comprising discs 20, 21, 22 and casings 83, 84 (apertured for the circulation of liquid helium) all of which carry inner coatings of superconducting material to screen the outer metal parts of the assembly from the magnetic fields generated in the interior. This reduces heat production by eddy-currents. The cryostat is completed by a vacuum chamber formed between vessels 37 and 38 a liquid nitrogen filled chamber between vessels 36 and 37 and an outer vacuum chamber between vessels 35 and 36. These vessels are all bolted together using seals, e.g. 48, 49 to ensure fluid-tightness. The vacuum chambers also contain activated charcoal 54 held in fine copper gauze pockets 55, 56. This enables a vacuum of 10<SP>-6</SP>-10<SP>-8</SP> Torr to be generated in the chambers. Connections to the capacitor windings are via conductors 27, 32, 30 soldered to copper tubes 28, 34, 31 which pass out through the cryostat cover 29 by means of sealed bushes 91. A plastics tube 94 insulates the conductor 28 from a nut 95 which compresses a gasket 93 on a washer 92.

Title: Vehicle braking pressure control device
Inventor: DOWELL FREDERICK SIDNEY
IPC: B60T8/26
Filed: 1965-06-08
Abstract: 1,142,009. Braking pressure control devices. DUNLOP CO. Ltd. 24 May, 1966 [8 June, 1965], No. 24105/65. Heading F2F. A braking pressure control device for controlling the distribution of braking pressure to the front and rear wheels of a vehicle comprises a valve housing 1 having an inlet 11 and an outlet 10 for connection to a fluid pressure source and the wheel brake operating mechanism of the vehicle respectively. A valve member 14 is housed in the inlet passage of the housing and is influenced by an inertia operated control mass 4 and an auxiliary control device. The mass 4 is surrounded by a cylinder 6 of a plastics material to act as a cushion between the wall of the valve housing and the mass and to damp movement of the mass. A resilient cushion 8 is also provided in the valve housing. On retardation of the vehicle the control mass 4 under the retardation forces and the force applied by the valve stem moves to allow the closure of the valve member 14 fluid pressure then being transmitted from the inlet to the outlet at a reduced rate through a by-pass incorporating a spring loaded piston 27. The auxiliary control device including a spring loaded plunger 19 acts on the valve member spring 18 such that, on the vehicle being loaded, a higher fluid pressure is required to provide an adequate deceleration, this higher fluid pressure depressing the spring loaded plunger 19 and thus reducing the biasing force on spring 18. A higher pressure fluid is thus allowed to flow through the outlet before the valve member 14 is allowed to close. In a modification (Fig. 2, not shown) the inertia control mass rocks about a projection formed at the lower end of the valve housing chamber and positioned about the stem of the valve member. Further, the mass may at its lower end be curved in two directions at right angles to each other and be mounted to rock on a pivoted plate, the auxiliary control device affecting the angle of tilt of the plate (Figs. 3, 4, not shown). Further, the mass may comprise a pendulum mounted below (Figs. 5, 6, 7, not shown) or above (Figs. 8, 9) the valve housing. In all cases the pivoting points of the pendulum are offset with respect to the axis of the pendulum arm such that fluid pressure acting on the arm tends to urge the pendulum arm away from the valve member closing position.
Patent GB-694970-A (GB)
Title: Improvements in or relating to the production of fats
IPC: C11C3/12
Filed: 1950-10-04
Abstract: Hard, brittle fats are obtained by hydrogenating under pressure the free fatty acids derived from a natural fat or oil, e.g. coconut or palm kernel oil, and re-esterifying with a polyhydric alcohol, preferably glycerol.  The free fatty acids may be distilled, before or after hydrogenation, to remove one or more fractions, prior to re-esterifying.  They are also freed from unsaponified fat by complete lipolysis.  An excess of polyhydric alcohol may be used in the re-esterification.  In examples: (1) refined fatty acids of palm kernel oil are steam distilled at 3 mm. and hydrogenated at 180 DEG C. and 5 atm with a nickel catalyst until the iodine number falls to 0.8-3.  The acids are then esterified with glycerol at 200 DEG  C. and 3 mm. with zinc dust as catalyst, and the fat refined; (2) vegetable oil fatty acids are distilled at 3 mm. and the fraction up to 172 DEG  C. removed, the remainder being steam distilled, hydrogenated, and esterified with glycerol as in (1).

Title: Improvements in the production of styrene polymers
Inventor: HINDS JAMES ROBERT
IPC: C08F2/00
Filed: 1968-05-21
Abstract: 1,269,936. Separation of volatile components from mixtures containing styrene polymers. DOW CHEMICAL CO. Ltd. 29 April, 1969 [21 May, 1968], No. 24225/68. Heading B1B. [Also in Division C3] Volatile components are separated from a mixture containing styrene polymers by passing the mixture through pipe 18 and heater 19 into a heated vessel 1 which is maintained under reduced pressure by a pump (not shown) connected to pipe 22. As the mixture drops from heater 19 to the liquid pool in the bottom of vessel 1, volatile components are vaporized and flow via pipe 22 to a condenser. Some of the partially stripped polymer is recirculated to vessel 1 through pipe 10 by means of gear pump 11, steam or nitrogen being injected at inlet 14. The recirculated material enters vessel 1 through dihead 13, and drops in the form of long narrow streams to the pool in the bottom of the vessel. Stripped polymer is withdrawn from the system through pipe 16. Heater 19 is maintained at about 245‹C. by circulating hot oil through it. Vessel 1 and pipes 10 and 16 are provided with heating jackets.

Title: Improvements relating to the control of electric motors driving windshield wipers
IPC: B60S1/08
Filed: 1955-08-24
Abstract: 775,631. Windscreen cleaners. ALFA ROMEO SOC. PER AZIONI. Aug. 24, 1955 [Sept. 17, 1954], No. 24341/55. Class 138(1) [Also in Group XXXVII] An electric motor 1 driving the blade of a windscreen wiper is controlled by a switch 3 having an "off" position and two operative positions. When the switch is set to engage contact 4, the motor is continuously energized. Movement of the switch to engage contact 7 energizes the heating-coil of a bimetallic strip 12 which is adapted to expand and to actuate a spring-biassed switch-member 8 for opening the heating circuit and closing the motor circuit. After a time delay, the bimetallic element cools sufficiently to allow the member 8 to snap back to its original position, so providing intermittent operation of the motor and preventing excessive wear of the wiper when the screen is only slightly wet. The switch 3 may be coupled to a rheostat for adjusting the current through the heating-coil when the switch is positioned for intermittent operation of the motor, thus controlling the on-off periods of the motor, Fig. 2 (not shown). The heating-coil may be connected in parallel with an adjustable resistor and in series with the motor so as to act as an overload release to protect the motor against excessive current, Fig. 3 (not shown). The thermal 'switch may be replaced by one of the clockwork type.

Title: A new or improved fluid-flow reversing device
Inventor: PAWLING FRANK
IPC: F16N25/02
Filed: 1951-10-19
Abstract: 727,239. Lubricating. EXACTOR, Ltd. Oct. 17, 1952 [Oct. 19, 1951], No. 24501/51. Class 12 (3) [Also in Group XXIX] A fluid flow reversing device, for use for example in lubricating systems, of the kind comprising a housing having means for connection to a pressure supply and to the two ends of a closed external circuit and three shuttle valves operable in three independent bores with closed ends in the housing, one valve, a pilot valve, being operable by return flow of fluid from the external circuit to change the supply pressure from one end to the other of the second valve, the main valve, thereby causing the main valve to change the supply pressure from one end to the other of the third valve to cause it to reverse the direction of flow through the external circuit, is characterized in that the three bores for the valves are parallel, and the housing is in two parts in face-to-face pressure tight relation, and passageways between the bores are in part formed by grooves provided in the mating face of one of the body parts. In the arrangement shown, a housing is in two parts secured face-to-face by screws, a part 1 being provided with a cylindrical bore 4 fitted with a main valve 5 and a part 2 having two cylindrical bores 12, 13 fitted respectively with a pilot valve 14 and a diverter valve 15. The valve 5 has an indicator 6. The housing has an inlet 31 for grease supplied by a pump, two outlets 32, 33 leading to the two ends of an external circuit containing one or more dispensing devices 41, and an exhaust outlet 34 which may be connected back to the grease reservoir. Internal passageways in the housing connect the conduits as necessary. With the valves in the position shown in Fig. 11, grease passes through inlet 31, passageways 102 and 111 to the outlet 32 and devices 41 are operated in succession. The return flow passes around the stem of the diverter valve 15 to passageway 110 and thence to one end of bore 12, causing the pilot valve 14 to move to the right, the grease at the other end of bore 12 passing to exhaust 34 through'passageway 109. The movement of the pilot valve cuts off pressure from the supply to the left of main valve 5 and applies it to the right of this valve through passageways 104, 106. The main valve is thus moved to the left, whereby inlet 31 is disconnected from passageway 102 and is connected to passageway 103. The diverter valve is then moved to the right causing the passageway 103 to be connected to the outlet 33 so that the grease begins to flow in the reverse direction in the external circuit. This initiates the return movements of the valves 14, 5 and 15.

Abstract: 1398121 Inertia switches NISSAN MOTOR CO Ltd 25 May 1972 [28 May 1971 24 June 1971 (2) 17 Sept 1971] 24777/72 Heading H1N An impact responsive switch comprises a receptacle having a cavity therein containing a stationary contact, a conductive element having a flat surface, a rollable contact movably supported on the flat surface and biased to a rest position spaced from the stationary contact, the rollable contact moving from its rest position to connect the conductive element to the stationary contact when subjected to a force of inertia greater than a predetermined magnitude and only when said force is in a direction within a predetermined angular range of less than 180 degrees. Several means of preventing completion of the circuit when the force is outside the prescribed angular range are disclosed in respective embodiments, all of which employ a ball member (27) of electrically conductive ferromagnetic material and a permanent magnet (26) to provide the bias to a rest position. In the embodiments of Figs. 1 to 6 (not shown) the ball is received in a special portion of the cavity having no stationary contact when the impact is not within the desired angle (6). In the case of Figs. 1 and 2 this special portion is a part annular chamber (22b) below the level of the flat surface into which the ball can drop. In Figs. 3 and 4 lower chambers (22c and 22d) are provided on each side of a conductive runway (28), while in Figs. 5 and 6 a generally V-shaped cavity has the stationary contact adjacent the apex and the arms form lateral chambers (29a, 29b) to receive the ball outside angle #. In the embodiment of Fig. 17 (not shown) an adjustable spring- loaded W-section member (51) assists the permanent magnet in holding the ball centrally and also retains the ball when it has been urged to an operated position. The stationary contact may be of resilient metal and split into strips (24a) to provide a cushioning effect. In two embodiments (Figs. 12 and 14, not shown) an additional contact outside the angle # is used to discharge a capacitor (43) in a special circuit (Fig. 15, not shown) and thus prevent actuation should the ball bounce against the stationary contact after impact outside the angle #. In other arrangements to prevent operation by bounce two switches are connected in series and have different rebounds provided by walls of different bulk modulus (Figs. 8A and 8B, not shown), of different radius to provide differing path lengths for the ball (Figs. 10A and 10B, not shown) or by cavities of different shape (Figs. 11A and 11B, not shown).
