Title: Improvements relating to valves for gas storage containers
Inventor: CHRISTIE ALBERT
IPC: F16K1/30
Filed: 1955-10-17
Abstract: 812,412. Valves. LP-GAS EQUIPMENT Ltd. Oct. 17, 1956 [Oct. 17. 1955], No. 29477/55. Class 135. A manually operable valve for gas storage containers wherein the work done during operation of the valve in overcoming the friction of the sealing means is always performed manually, comprises a body 10, Fig. 1, which has a screw-threaded plug portion 11, for insertion into the container and a cylindrical chamber portion 24 having an inlet port 13, Fig. 2, outlet ports 36 (not shown), perpendicular to section plane of Fig. 1, and a valve seat which cooperates with a valve closure member. The closure member is a cup element 31 containing a sealing washer 34, retained therein by a rod 35 which is screwed into the cup element, and is urged by a spring bearing on an end plug 26 towards the closed position. The rod 35 apart from an enlarged guiding head 37 is a clearance fit in a bore 30 to provide a flow passage between chamber 24 and ports 36. A hollow cylindrical boss 41 houses an operating spindle 42 that is provided with a cam 44 so that rotation of the spindle actuates the closure member through rod 35. The spindle is sealed by a ring 48 held in the boss by a screwed plug 49. A handle 50 screwed to the spindle and shown in the closed position has a shoulder 53 that co-operates with a stop 52 on the boss 41 to limit the travel of the handle between open and closed positions. When the valve is open the position of the handle prevents a valve cover from being placed over the valve. To the lower end of the plug portion 11 is screwed an excess flow valve that comprises a body 15 having an axial bore for a valve member 16 which has a recess 17 leading to ports 18 communicating with the bore 13 in the plug portion. The valve is normally urged by a spring 19 to its open position where it rests on a filter disc 20 located by a plug 21. Excessive flow causes the valve member to rise and seat on shoulder 23 but a restricted flow is provided by a small axial bore 22 in the valve member. The outlet ports 36 communicate with a bore in a spigot 38 having an external thread for the coupling of a pipe leading to a gas appliance. Situated within the bore is a single beat lift valve of known kind that prevents the escape of gas when the valve is uncoupled but is opened by the act of coupling the pipe. A screwed cap 40 is also provided to protect the valve when it is uncoupled. In an alternative embodiment, the cam and follower assembly 44, 35 may be replaced by a pin and slot arrangement in which case the spindle 35 may also be provided with sealing means as in this case the closure member has positive manual actuation in both directions.

Title: Improvements in and relating to apparatus for the treatment of materials or objects in liquid baths
IPC: C21D1/63
Filed: 1949-11-21
Abstract: <PICT:0675002/III/1> An apparatus for immersing and agitating objects in a degreasing bath has a tray on which the objects are placed, a supporting structure for the tray and a mechanism driven uni-directionally and incorporating a catch or latch element which is rendered inoperative to impart one motion to the tray and which is engaged to change the motion of the tray into one of a different speed and amplitude.  As shown, the tray 7 is supported from lever 1 pivoted at 2 to the main frame of the device, and the crank means 10 imparts a reciprocating motion to the arm 1 through the lever 12 which has a catch 12b engaging pin 13.  The tray will reciprocate with a fairly large amplitude and speed.  The second lever 8 will engage the pin 11 only when the lever 1 is at or near its lowest point, when the lever 8 will take the weight off pin 13 allowing the spring 14 to disengage the catch arrangement; thus the tray will be subjected to a reciprocating motion of smaller amplitude and speed. In operation, the objects are placed on the tray when it is at its highest point and the machine is set in motion with the catch on. The objects are quickly immersed and then agitated in the liquid until such time as the operator re-engages the catch 12b using handle 12a.  The tray is then lifted clear of the bath and limit switch 16 cuts off the motive power at the highest point of the movement. Other embodiments are described and illustrated.
