Title: Improvements relating to speed indicators
IPC: G01P3/10
Filed: 1928-05-18
Abstract: 292,156. Mombur, G. June 17, 1927, [Convention date]. Impulse and momentum speed indicators.-In a speedometer of the impulse type comprising a control wheel actuated electromagnetically proportionally to the speed the control wheel, at an instant near the end of the operating period, is engaged by a measuring wheel connected to the indicating pointer the wheel being released for movement by an oscillating constant time member and held at the end of the period while the control wheel is released and returned to initial position. As shown, the control wheel 1, Fig. 2 is actuated, against the action of a spiral spring 2, by pawls 4 on the armature of an electromagnet excited in accordance with the speed. Adjacent the wheel 1 is a measuring wheel 5 acted upon by a spiral spring 6 and retained in set position by a pawl 8, Fig. 1, controlled by a spring 10. The other end of the spring 10 is connected to a two-armed oscillatable member 13, 14 movable in one direction against the spring action by the armature 16 of an electromagnet 17. The arms 13, 14 carry projections 21, 22 that co-operate with notches 24 in a disc 23 integral with a ratchet-pinion 20 actuated by a pawl 19 pivoted on the arm 14. In operation when the speed is decreasing, the projection 22 is presented to a notch 24 the member 13, 14 is rocked to cause a pin 12 on the ram 13 to disengage the pawl 8 and release the measuring wheel 5 whereupon the spring 6 rotates the wheel until the pin 7 thereon strikes a pin 25 on the control wheel. The armature 16 is then attracted by its electromagnet and the member 13, 14 is rocked in the opposite direction, the projection 21 entering a notch 24 causes engagement of the pawl 8 and release of the actuating pawls 4 to free the control wheel 1 by means of a pin 26 on the arm 14 whereupon the wheel returns to initial position. If the speed is increasing the measuring wheel 5 will be driven by the control wheel 1 before the pin 12 comes into action.

Title: Improvements in or relating to vehicle suspension systems
IPC: B64C25/60
Filed: 1947-06-05
Abstract: 629,565. Spring suspensions. BRITISH MESSIER, Ltd., and CONWAY, H. G. June 5, 1947, No. 14915. [Class 108 (iii)] In a vehicle suspension unit comprising telescopic legs attached respectively to the vehicle and a vehicle wheel, the inner leg of the unit constitutes the cylinder of a liquid spring having a ram or plunger therein which extends into the outer leg. As applied to an aircraft undercarriage leg, a tubular member 13 carries at its lower end a wheel 15 and telescopes into an upper cylindrical member 11 pivotally connected to the aircraft at 12. The member 13 carries at its upper end a pistonhead 18 through which a ram 19 supported by a diaphragm 21 in the upper part of the member 11, projects into a liquidfilled space 28 of the member 13. The pistonhead which is provided on its under-side with a ring valve 24 co-operating with damping apertures 25 closes the upper end of an annular liquid-filled space 29 between the members 11 and 13. Damping apertures 26 in the diaphragm 21 communicate with liquid-filled spaces 22 and 30. One or more of the apertures 26 may be closed against passage of liquid into space 22 by means of a non-return valve 27. In operation, relative inward movement of the members 11 and 13 is resisted by the liquid in space 28 and liquid is displaced from the space 30 through the aperture 25 into the space 29 and also through the aperture 21 into the space 22 wherein the liquid level is raised against a spring-loaded piston 31. On rebound of the member 13, the piston forces liquid above the diaphragm 21 back on to space 30 to maintain the latter filled and the rebound action is controlled by the passage of liquid from the space through the restricted apertures 25 in the piston - head 18. In a modification the spring-loaded piston 31 may be replaced by compressed air. A filling plug 33 communicates with space 22 and a longitudinal duct, Fig. 2 (not shown) in the ram 19, leads from the space 22 to the space 28 in the member 13. A normally closed spring- loaded valve at the lower end of the duct permits filling of the space 28 when the telescopic members 11 and 13 are withdrawn to their fullest extent. Relative rotation of the members 11, 13 is prevented by a pair of links (not shown), as described in Specification 412,191.

Abstract: 553,767. Automatic control systems. HUGHES, C. W. Dec. 2, 1941, No. 15520. [Class 38 (iv)] Voltage ; variables in general.-Two photoelectric cells are associated with variable-mu valves arranged in push-pull to develop a current which varies with differential illumination of the cells whereby a change in a variable condition may be corrected. As shown in Fig. 1 the grid circuits of two variable-mu valves 8, 9 are excited from a transformer 15 and variably biased in accordance with changes in the condition controlled by the potential drop in a resistance 5 which occurs when a light beam controlled by the condition disturbs the balanced illumination of the cells 1, 2. The output from a transformer 12, to which the valves are connected in pushpull, is amplified and used to correct the condition, which may be the voltage of a circuit 17 to which an instrument 19, controlling the incidence of light on the cells, is responsive. In a modification two further valves are connected respectively in phase opposition with the valves 8, 9, the grid bias of the opposed pairs of valves being controlled by separate resistances in parallel circuits each containing one of the photoelectric cells. The amplified output from the transformer then reverses in phase with a change in the sense of departure of the condition controlled from its correct value and may be superposed on a circuit the voltage of which is to be controlled or employed to operate a reversible correcting motor. The transformer 15 may be excited from a source of controlled frequency such as a valve-maintained tuning fork.

Abstract: 770,887. Discharging coke oven batteries. KOPPERS GES., H. May 31, 1955 [July 5, 1954], No. 15534/55. Addition to 741,398. Class 51 (2). [Also in Group XXVIII] In apparatus for discharging a horizontal coke oven battery in which a locking device for the latches of one or both doors of each oven is released by low-pressure fluid supplied through a control conduit extending across the oven, and a fluid-pressure operated lock on the ram motor is released by highpressure fluid supplied through the control conduit as disclosed in the parent Specification, the low-pressure fluid is automatically cut off from the control conduit by a control valve to which high pressure fluid is supplied when the coke guide machine is positioned for coke discharge. In the preferred embodiment, the control valve 7 is secured to a buckstay 1 by a pipe-coupling part 3 extending therethrough, and having an axial bore 5 communicating with a valve chamber 6, which is connected to another valve chamber 9 by a bore 8. The chambers 6 and 9 communicate with pipes 22 and 23 respectively through bores 10 and 11 in plugs 13 and 14 formed with peripheral grooves 17 and 18 co-operating with banjo couplings 15 and 16. Ports 19 and 20 connect the bores. 10 and 11 with the grooves 17 and 18. The pipe 22 communicates with the low-pressure fluid main, and the pipe 23 with the control conduit. The pressure fluid is compressed air, though a hydraulic liquid could be substituted. A plunger 26 extends through the bore 5 into the valve chamber 6 and carries a valve member 33 which is urged towards a seating 36 by a spring 51, but in the position shown in Fig. 3 is held against a seating 37 by a stud 49 on a spring-pressed lever 48. In operation, the coke guide machine operator swings the lever 48 away, releasing the valve member 33, which is pressed against the seating 36 by the spring 51, thus allowing the passage of low pressure fluid through the control valve to the control conduit so that the locking devices on the coke over door latches are released. When the oven doors have been removed and the coke pusher and coke guide machines have been correctly positioned, locking of the flopper plate in position couples a high pressure line to the coupling port 3. The high pressure fluid forces the valve member onto the seating 37 against the pressure of the spring 51 and the low-pressure fluid, allowing passage of the high pressure fluid through the control conduit to release the lock on the ram motor. Specification 768,809 also is referred to.
