Title: Automatic liquid shut off device
IPC: B67D7/48
Filed: 1938-01-25
Abstract: 508,874. Fluid-actuated valves. WILDEBOUR, C. W. Jan. 25, 1938, No. 2415. [Class 135] An automatic liquid shut-off device more especially for the discharge end of a petrol dispensing hose comprises a nozzle chamber formed between two partitions 18, 21 and containing a pivotally-mounted flap valve 24 which in the normal position is open and lies at one side of and substantially parallel ;to the path of flow through the nozzle but is moved into the closed position when the nozzle is submerged by the liquid in the receptacle being filled, As shown in Fig. 2, the nozzle comprises two parts 10, 11 screw-threaded together with a washer 17 to prevent leakage. The part 10 is connected by a flexible tube to the manually operated control valve of a dispensing hose. The part 11 has shoulders 15, 16 to receive the partitions 18, 21 respectively, these being held in place by set screws. The partition 18 has an offset circular aperture 20 which is smaller than a semi-circular valve seat aperture 22 in the plate 21. The valve member 24 is substantially semi-circular in shape and is normally held in the position shown by a spring 26 arranged about its pivot, the opening movement being limited by the edges of the valve contacting the inside of the member 11. The flow past the. valve member creates a vacuum in the chamber 27 behind the valve and the liquid which enters this chamber when the lower end of the nozzle becomes submerged forces the flap valve sufficiently into the main fluid stream as to be closed thereby. A slot (not shown) in the edge of the valve member allows liquid to leak away after the manually-operated valve is closed. In a modification, Fig. 7, a deflector 31 formed on a partition 32 is mounted within the nozzle member 30 and the valve member comprises a part 33 normally held by a spring 37 against a guard member 39 so as to be out of the fluid flow. The lower portion 34 of the valve is exposed to the jet from an L-shaped tube 36 mounted in a partition 32<1>, the force of the jet aiding the spring 37. The force of the jet is reduced when the nozzle is submerged and main flow acting on the portion 34 tips the valve 33 sufficiently into the main flow to be closed thereby.

Title: Improvements relating to horizontal coke-oven batteries and the operation thereof
Inventor: HORSFALL TIMOTHY EDWARD SCOTT
IPC: C10B41/04
Filed: 1958-01-28
Abstract: 903,711. Locating conducting or magnetic bodies. WOODALL-DUCKHAM CONSTRUCTION CO. Ltd. Jan. 7, 1959 [Jan. 28, 1958], No. 2891/58. Class 37. [Also in Group XII] In a horizontal coke oven battery, the proximity of a coke car to the coke guide machine affects current in an oscillatory circuit and so provides an indication of the presence of the coke car. Fig. 2 shows the coke guide machine 1 movable on rails 2 alongside the horizontal coke oven battery, not shown. A radio frequency transmitting element 10 and a receiving element 9 are supported from the side of the coke guide machine by a bracket 12. The coke car 4 is propelled by an electric locomotive on rails (not shown) parallel to rails 2. When the coke car 4 is in the correct position relative to the machine 1, a shield 18 carried by the car 4 is interposed between elements 9, 10 so reducing the energy picked up by element 9. In the arrangement shown in Fig. 5, the elements 9, 10 are duplicated, the transmitting elements 10, 10a being fed from an oscillator 28 operating on a frequency between 20 and 150 kc./s. The elements 9, 10 may be either inductive or capacitive. The receiving elements 9, 9a are respectively fed to valve or semi-conductor detectors 30, 31, each detector comprising a circuit tuned to the required radio frequency. Relays 32, 33 associated with each detector are energized in the absence of the car 4 but are released when the shield 18 is interposed by the car between elements 9, 10. A further relay 29 is energized whenever the oscillator 28 is operating correctly. When the car 4 is in the correct position the contacts in circuit 34 will all be closed to initiate an audible or visible signal or to operate a control circuit associated with the coke ejecting ram at the other side of the coke oven. Radio frequency energy is also fed via capacitor 35 and contacts 32b, 33b to detector 31. This arrangement prevents relay 33 being released should the car 4 approach the elements 9, 10 from the reverse direction. Fig. 4 shows an alternative arrangement in which the transmitting elements 10 are omitted. Inductive or capacitive elements 9, 9a are coupled to valve or semi-conductor oscillators 22, 23 in such a way that the proximity of the shield 18 alters the amplitude of or terminates the oscillation. This causes relays 24, 25 to energize, closing a control circuit 26. Relay 25 will be short circuited by contacts 24b, 25b if relay 24 is energized first by a car approaching from the wrong direction. Fig. 3 (not shown) relates to a capacitive pick-up suitable for use as elements 9 or 10. The pick-up comprises a metal box having one open side and containing a flat plate electrode, the open side being closed by a heat-resisting ceramic block. Specifications 720,469, 729,964, 741,398, 745,509, 768,809, 770,887, 801,116, 801,117 and 839,650 are referred to.
