Title: Couplings incorporating shut-off fluid control valves
IPC: F16L29/00
Filed: 1957-04-24
Abstract: 865,440. Valves. SULZER FRERES S.A. April 24, 1957 [May 2, 1956], No. 13085/57. Class 135. [Also in Group XXVIII] A coupling 2 for interconnecting two members (e.g. a pressure indicator and a cylinder of an I.C. engine) incorporates a shutoff fluid-control valve 19. The coupling 2 is screwthreaded at 5 and 6 to receive the two members, only one, the connection member 9, being shown. When connected, the member 9 seats against a packing 12 on a shoulder 11 of the coupling housing 2 and so closes a series of ports 15 which extend from the inside to the outside of the housing 2. The shut-off element is a symmetrical double valve having bored stems 19, 20 and seating surfaces 16, 17, one of which, say 16, is biased by the loading spring 14 against the seat 13. The element 19 is reversed when the surface 16 wears. When the member (e.g. the pressure indicator) is screwed on to screw thread 5 a part thereof engages the element 19 to move the surface 16 from the seat 13 so providing a flow path between the members connected to the coupling. Partial unscrewing of the connection member 9 to an extent determined by the collar 40 connects the bore 8 of the member 9 to atmosphere through the ports 15 which are disposed tangentially so that the reaction of the escaping fluid rotates the member 9 until it again seats on the packing 12. In this way dirt particles may be ejected from the I.C. engine cylinder before final connection of the pressure indicator. In another example the member screwed on the screw-threads 6 has a vent passage adapted to be closed by the bottom surface of the coupling housing.

Abstract: 508,780. Coking processes; gas-condensing plant. HUMPHREYS & GLASGOW, Ltd., and MENGEL, E. C. Oct. 4, 1937, No. 13356/39. Divided out of 506,994. [Classes 55 (i) and 55 (ii)] In the carbonisation of solid fuels by circulating a heated gas therethrough, the gases leaving the retort are passed through a baffle box or dust catcher so arranged in the outlet pipe that dust is trapped before the temperature of the gases falls and that pitch and tarry vapours are not deposited but are removed subsequently. The charge of briquettes is fed from a charging device 2 into a carbonising and cooling chamber 1 from which the coked residue is removed through a chamber 20 and conveyer 22. Hot gases from a regenerator 6 are supplied through a bustle pipe 4 to the upper part of the shaft, and the distillates pass while still at high temperature through a dust catcher 25, and then to a seal pot 26, where heavy tars are trapped. The gases then pass through primary and secondary condensers 28, 29, a cyclone separator 31 for removing tar fog, and a fan 33 which is maintained at such a temperature that tar particles are flung off the fan blades. The gas then enters a recirculation pipe 11 from which a pipe 34 branches to a scrubber 35, relief valve 37, pipe 36, and balancing holder 38 to which the gas passes when the pressure in the gas circuit rises. A branch 39 dips into a liquid seal 40 through which gas passes back into the circuit when the pressure falls. Surplus gas is taken off through pipe 41. A blower 42 supplies air to the regenerator 6 when gas is to be burned therein. An automatic operator 43 controls the various valves. Specification 469,175 is referred to.

Patent GB-135524-A (GB)
IPC: F16D31/02
Abstract: 135,524. Shaw, H. S. Hele-. Sept. 12, 1917. Clutches and speed-varying mechanism.-In an hydraulic clutch, the driving-shaft 1, Fig. 1, carries a body 3 provided with cylinders 5 communicating with a closed circuit consisting of passages 10, 10<a>, Fig. 3<b>, valves 11 controlling the circulation of liquid, and the pistons 7 co-acting with cams 8, preferably of the swash-plate type, keyed to the driven shaft 9. In order to maintain the circuit full, liquid is supplied from an external source through passages in a running joint 18, pipes 16, and non-return valves 17. In the form shown, the valves 11 are partially or entirely closed against the action of springs 20, Fig. 3, by pressure liquid from a cock 22 passing through passages in the joint 18, pipes 21, and ports 23. Should the circuit not be full at this time, the pressure liquid passes into it by channels 25 and fills it before operating the valves. When the clutch is to be thrown out, the cock is operated to relieve the pressure, the springs 20 open the valves, and liquid in the circuit passes out through the passages 25, thus allowing springs 14 to move annular rings 12 towards each other and free them from the swash-plates 8. In a modification, the valves 11 are operated mechanically by connexions from a sliding collar on the shaft 9, and the liquid for replenishing leakage is supplied from the casing by a pump carried by the casing and driven by epicyclic gearing. In a further form employing one swash-plate only with a thrust bearing 34, Fig. 5, at the opposite end, the valves 11 and valves 33 are carried by a longitudinally-movable spider 32. When in the position shown, the clutch is free and pressure in the closed circuit is relieved through the valves 33. In all conditions of working, leakage is made up from the casing through automatic inlet valves 37<a>, Fig. 7, which are balanced against centrifugal force by a pivoted lever 37d, one end of which is in contact with the ball 37a while the other carries a similar ball 37e. The spideroperating means is connected to mechanism for applying a brake to the shaft 9 when the clutch is thrown out, and to means for moving the annular thrust plate out of contact with the swashplate. In all forms, the driving and driven memhers may be positively connected in emergency by means of pegs or screws 41.
