Title: Improvements in power assisted steering mechanisms
IPC: B62D5/08
Filed: 1949-10-12
Abstract: 662,724. Fluid-pressure servomotor control systems; fluid-actuated valves. BENDIX AVIATION CORPORATION. Oct. 12, 1949 [Nov. 17, 1948] No. 26241/49. Class 135. A servo-assisted steering gear comprises a piston 48 having a rack 54 coacting with a gear quadrant 56 connected to the steered members and a screw-thread connection 44, with a rotatable and axially movable steering column 38, the latter carrying spaced discs 98, 100 for actuation of valves 20, 22 upon axial displacement of the column. The steering column is centred by coned spring washers 124 which are pre-loaded to permit of direct manual actuation of the piston through its screwed connection with the column if the resistance to movement is low. In the event of high resistance the column is displaced so that one of the discs 98, 100 operates one of the valves. Thus the disc 98, when displaced to the right moves a valve seat member 91 which normally permits communication between a chamber 52, to the right of the piston, and a reservoir 12 through a conduit 66, a passage through a tubular valve member 101, a chamber 74 and a conduit 72. Such movement of the member 91 interrupts this communication and subsequently moves the valve member 101 away from a fixed seat 78 to permit passage of pressure liquid from an accumulator 18 through a conduit 24 and the conduit 66 to the chamber 52. The consequent movement of the piston recentres the steering column. The valve 22 is similar to the valve 20 and directs pressure liquid to a chamber 50 upon displacement of the steering column in the opposite airection. A spring-loaded valve 132 prevents the formation of a partial vacuum in the pressure supply conduits 24, 26 should the steering gear be operated during a failure of the supply pressure.

Title: Means for separating hop leaves and flowers
IPC: A01D46/02
Filed: 1947-09-30
Abstract: 639,595. Pneumatic separating. BROOKES, A. E. Sept. 30, 1947, No. 26366. [Class 117] Hop leaves and flowers are separated by conveying the mixture to a discharge point on a conveyer a so as to discharge the materials into the air, and a suction effect is created as by a fan g above the free leaves and flowers immediately after they have left the conveyer to produce an upwardly directed air stream such as will carry the leaves upwardly and allow only the flowers to fall. The mass of mixed material, e.g., from a conveyer c, may firstly be fed to a separator b such as an inclined grid which separates the loose petals and/or seeds from the leaves and flowers. The " throughs " from the separator b may fall on to a conveyer d for delivery into a receptacle e together with the flowers from conveyer a. A shoot k may be provided at the discharge end of the conveyer a to receive the heavier matter such as leaf stems or sprigs from the conveyer a. In an alternative apparatus the separator b is dispensed with and the air duct containing the fan has associated therewith a chamber having a rotary screen around the entrance thereof to intercept the leaves but allow the petals to pass through into the chamber from which they are discharged through a rotary shutter to join the stream of flowers. The leaves are carried by the rotary screen to a position opposite a horizontal duct where they are detached by an air stream flowing to a fan located in the horizontal duct.

Filed: 1971-04-19
Abstract: 1307453 Cathode materials and processings RCA CORPORATION 19 April 1971 [5 May 1970] 26496/71 Heading H1D A secondary electron emissive electrode comprises a deposit of Sb activated with K and Cs on the electrode surface. In a photomultiplier application electron from a photocathode 16 also of Sb activated with K and Cs are focused by electrodes 18-21 on to a first dynode 24 of Ni coated with Sb-Cs-K to give a high secondary electron yield. An Sb bead 50 for evaporating Sb on to the first dynode and two Sb beads 51 for evaporating Sb on to the inside surface of the glass faceplate 14 of the photomultiplier, are bonded to resistance heating wires. Resistance heated channels are provided for Cs and K vapours. The Cs channel contains a mixture of Cs 2 CrO 4 , Zr and W, and the K channel contains K 2 CrO 4 , Al and W. During manufacture the tube is exhausted and Sb evaporated on to the faceplate and first dynode surfaces then first K and then Cs are alternately vaporized to give a maximum photo-electron sensitivity during which the tube is maintained at 170‹ C, such that the photocathode and first dynode are simultaneously activated. Superficial oxidation may then be used to increase the secondary electron emission. In a further embodiment all dynodes may be coated with Sb-Cs-K. The dynodes may also be Sb-coated prior to assembly, obviating the need for separate Sb sources near each dynode. In an alternative method of manufacture the dynodes are first coated with Sb and activated with Cs and K and superficially oxidized, then finally a photocathode layer of Sb-Cs-K is formed without oxidation.

Title: Improvements in or connected with the measuring or measuring and recording of the flow of fluids through conduits
IPC: G01F1/00
Filed: 1924-11-08
Abstract: 247,636. Beck, W., and Coombs, E. P. Nov. 8, 1924. Liquid-level pressure gauges; indicating means for; with recording, integrating, and registering apparatus. -Compressed air is admitted to a conduit to balance the heads on either side of a constriction in the conduit and the pressure of the air necessary to do this is measured by a gauge preferably of the bell or diaphragm type. Nozzles or chests 4 are arranged on opposite sides of an opening 2 which can be varied by moving a weir 3 in an open conduit 1 through which liquid is flowing. Pipes 5 lead from the nozzles to a compressed air tank 6 and pipes 7 lead from the nozzles to the interior of bells 10 suspended in liquid in tanks 11 communicating at the bottom. A buoyant balance weight 13 of conoidal shape working in the tank 11 of one of the bells is connected by a cord to the right-hand bell which is also connected to the other bell, the cords passing over pulleys 15 on a gantry 16. In use, the valves 8 are opened to supply air to the nozzles and the heads of liquid on opposite sides of the orifice balanced whereupon the pressures of air within the bells will cause the weight 13 to move up or down and the index 17 to move over a scale 18. The floor of the down stream part of the conduit is higher than the up stream part, while the airdischarge openings in the nozzles are lower than the down stream floor, so that they are always sealed with liquid. In a modification a pointer moved by the balance weight moves over a time driven chart and an incline carried by the weight serves to limit the stroke of a time-controlled pneumatic ram which through rack and ratchet gear drives an integrating mechanism. In a further modification the air under pressure is led to the inside and outside of a bell suspended in a closed tank, the buoyant float being arranged within the bell. Specifications 7469/87, [Class 97, Philosophical instruments], and 7598/11, [Class 69 (i), Hydraulic apparatus &c.], are referred to.
