IPC: F16K5/06
Filed: 1968-12-20
Abstract: 1,218,478. Valves. HILLS-MeCANNA CO. 20 Dec., 1968 [28 Dec., 1967], No. 60752/68. Heading F2V. A ball valve comprises two annular valve seats 74, (72) supported on respective seat support surfaces 80, (78) and slidably engaging a flow control ball 20, each valve seat comprising two annular seal support springs 98, 100, two annular seat seals 82, 84 formed of yieldable polymeric material, each seal extending radially outwards in continuous relation to the adjacent support spring, and there being means clamping together the seals 82, 84 and the springs 98, 100 in assembled relationship. The clamping means includes two base ring elements 94, 96 and an annular series of cap screws 112. The ball 20 is assembled into the valve chamber and subsequently removed from it for servicing through a circular access opening (26), Fig. 1 (not shown). The L-shaped spaces 130, 132 allow dynamic action of the seat seals 82, 84 which are preferably formed from a polytetrafluoroethylene. An annular thrust spring 146 acts simultaneously on both springs 98, 100 to urge the latter away from each other. Thus, in the event of the thermal collapse of the seals 82, 84, the ends 138, 140 of the springs 98, 100 are urged into sealing engagement with the external ball surface 76 and the seat support surface 80. Since fluid enters the space 150, the effectiveness of the seat seal increases progressively with the differential fluid pressure on the ball 20. A tool (152), Fig. 2 (not shown), can be inserted in a groove 162 to remove the seat support surfaces for cleaning.

Patent GB-692108-A (GB)
Abstract: 692,108. Poultry battery-cage feeding arrangements. ROOCROFT, R., and TAYLOR, T. Dec. 5, 1951 [Oct. 10, 1950], No. 24673/50. Class 5(ii) [Also in Group XXIV] Reversing gearing is interposed between an electric motor and the cables which reciprocate the carrier 7 of the feeding and drinking troughs. Stops 12a on the cables 12 engaging eyes 14 on the carrier 7 permit a dwell at the end of the travel of the carrier. The carrier also engages stops 15 on a rod 13 which is pivoted to the throwover lever 30 of the reversing gearing. The drive from the motor takes place through a pulley 17 and worm-and-wheel gearing 16a, 20. About the axis of the wheel 20 swings a plate 24 carrying pinions 25, 26, the pinion 25 being in engagement with the worm-wheel 20. Depending on the position of the plate 24, the pinion 25 drives, either in one direction through the pinion 26, or directly in the opposite direction, a pinion 29 on the shaft 28 which also carries the pulley 10 over which runs the cable 12. An opening 27 in the plate 24 permits the latter to swing about shaft 28 when actuated by the rod 13. At its upper end the lever 30 is pivoted to a cylinder 32 containing a spring-pressed piston 34 and ending in a fork which takes over a pin on the swing- ing plate 24. This ensures a rapid throwover beyond the dead-centre position, a movement limited by a stop 36 and assisted by a lever 37 having projective pegs 39, 39 engaging the cylinder 32 and plate 24 respectively.
