Title: Improvements in velocity measuring system
IPC: B60T8/172
Filed: 1968-06-19
Abstract: 1,203,685. Measuring speed electrically. GENERAL ELECTRIC CO. June 19, 1968 [June 23, 1967], No.29106/68. Heading G1N. The speed of a vehicle is measured by an AC tachogenerator whose signals are converted to a train of double frequency pulses of constant amplitude and duration which are averaged to provide a measure of the speed. The pulse duration is adjustable to allow for variations in the diameter of the wheel associated with the tachogenerator. As shown Fig. 1, a vehicle 18 carries and AC tachogenerator 10 (12) on each of two axles 16, 14. The AC output triggers a multi-vibrator 48, 72 respectively at the zero levels, the pulse width being adjustable. The AC signals are also fed through frequency to analog converters 24, 26 and the larger output opens a gate 54 or 56 to enable the higher velocity to be measured. Thus the pulse train output from multivibrator 48 or 72, whichever represents the higher velocity, is fed through its opened gate 54 or 56, and the trailing edge of each pulse triggers a generator 90 of precision length pulses. The combined pulse trains are fed to a chopper 100 to produce pulses of constant amplitude and duration which are averaged to measure the speed.

Title: Improvements relating to weighing scales
IPC: G01G23/00
Filed: 1934-10-16
Abstract: 441,032. Automatic-feed weighers. REUTHER, W., 83, Adolf Hitler Strasse, Hennef-on-the-Sieg, Germany. Oct. 16, 1934, No. 29638. [Class 143] Relates to apparatus for weighing the residue or partial load remaining in the weigh hopper of an automatic weighing scale after a series of weighings and consists in providing additional bearing members for co-operation with the residue, steelyard, for the purpose of securing a long lifting movement when raising the weights pan prior to ascertaining the weight of the residue. The additional bearing members 9 may be rotated from an horizontal inoperative position to the vertical operative position shown, by means of a handle 12 to form a bearing for a projection or knife-edge 11 on the residue steelyard 14. The sliding poise weight 13 is then moved to its outer position shown, and the steelyard pressed down so as to raise the weights pan 2 by means of a knife-edge 15. This movement permits the weigh hopper 4 to descend and allows the feed-gate actuating lever 6 to slip past the hopper projection 5 and free the hopper. The residue steelyard and the poise weight 13 are now returned and the bearings 9 are turned down out of operation, the steelyard then resting on its knife-edge fulcrum 16. The residue may now be weighed by adjusting the poise weight, and the weight read off on graduations on the steelyard. In modifications the bearings 9 instead of being rotatable are movable vertically or horizontally ; or instead of the bearings 9 being movable, the projection 11 is movable along the steelyard.

Abstract: 1,162,583. Valves. LEONARD VALVE CO. 29 June, 1967 [18 July, 1966], No. 30043/67. Heading F2V. A hot and cold water mixing valve has two inlets (2) and a common outlet 6. The inlets are connected respectively to chambers 11, 12 from where the water flows to the mixing chamber 9 respectively via hot water control valve 60, inlet passage 15 and outlet passage 16 and via cold water control valve 61, inlet passage 18 and outlet passage 17. The control valves are mounted on valve element 26 having a longlead screw thread connection with bush 20 so that rotation opens both valves simultaneously. The hot water outlet passage 16 is initially blocked by land 30 on the valve element so that only cold water passes out of outlet 6. Further movement of the valve element causes land 30 to progressively open hot water outlet passage 16 and close cold water outlet passage 17. Hot and cold water inlet and outlet passages communicate via a fluid-pressure equalization chamber 7 having a liner 13 and in which slides a valve member 42 provided with hot and cold water-separating land 45 and inlet control lands 43, 44. Inlet pressure is communicated to the respective ends of the valve member 42 via axial passages 56, 58 and radial passages (55), (57) so that if the pressure of the inlet hot or cold water rises the valve member 42 will move to cause either land 43 or land 44 to restrict the flow through the respective inlet passage in which the pressure has risen. Grooves 46, 50 in the lands 43, 44 and recesses 65, 68 in the liner 13 help to balance the lateral fluid pressure on the lands and prevent the valve member 42 from sticking. In another embodiment screw-in seats are provided for the closure elements on valve element 26 which is non- rotatable but axially movable by means of a long-lead screw thread connection with an axially fixed rotatable bush. The liner 13 is provided with circumferential grooves co-operating with radial ports so that whatever the angular position of the liner the hot and cold water inlet and outlet passages will communicate with the fluid pressure equalization chamber.
