As shown, the continuous web 3 is wound on to a storage roll 21 together with a wax paper slip from a roll 23; alternatively, the web 3 may be wound directly on to the forming mandrel. Additional polymer material may be applied to one or both faces of the web before it is wound upon the forming mandrel. Before the tube is sliced, it may be removed from the forming mandrel and dipped to provide a layer, or an additional layer, of polymer on the inner or outer surfaces of the tube. After the gaskets have been sliced from the tube they may be dipped to provide a polymer coating 42, 44 on their cut end faces. Curing of the polymer may be effected after the gaskets have been sliced from the tube and, if desired, during their use between parts to be sealed. The packing material of the web 3 which forms the laminations 34 may be cork, asbestos or fibre reinforced synthetic rubber. The polymer material may be a blend of nitrile rubber or neoprene and phenolic rsin.

A safety control device for shutting off the gas supply to a number of main burners on failure of any one of the main burner flames or pilot burner flames comprises a solenoid valve 1 controlling the gas supply to the main and pilot burners and energized by the anode current of an electronic valve V 1 , and flame rectifiers 12 located in the pilot flames. The current through each flame rectifier develops a negative bias across a separate resistance 11 in the grid circuit of a separate electronic valve V 2  . . . V 6  and prevents the valve V 2  . . . V 6  from conducting. The anode circuits of all the electronic valves V 2  . . .

If any one flame fails the negative bias on the grid of its associated valve V 2  . . . V 6  disappears and the valve conducts to bias the first electronic valve V 1  to beyond cut off and the solenoid valve is de-energized and closes. The solenoid valve 1 comprises a closure member controlling the flows of gas to both the pilot and main burners and urged to closed position by a spring and held in open position by an electromagnet. The valve is opened initially by means of a push-rod which when pushed in against spring action pushes the valve closure member off its seat and allows a second valve closure member to prevent the flow of gas to the main burner but not to the pilot burner. The flame rectifier consists of two metal probes, one having a surface exposed to the flame at least four times as great as that of the other.

[Also in Groups XXV and XXX] A shaft door 3 of an ammunition hoist consists of a steel plate with reinforcing ribs 4 and is provided with a groove 5 containing packing which engages a flange 7 on the door frame 1 to form a gas-tight seal when the door is locked and means are provided to prevent accidental unlocking of the door when the hoist cage is not at rest in front of the door. The door is locked by bars 10 which engage in guides 11 on the door and which, at one end, engage wedges 12 on the frame and at the other end, are pivoted to a plate 15 which is freely rotatable on a shaft 18. The locking mechanism may be actuated by a handle 21 secured to the shaft 18, which is rotatably mounted on the door, when a connecting arm 22 secured to the shaft 18 is coupled by a pin 27 to an arm 25 secured to the plate 15. The pin 27 is normally urged out of engagement with the arm 22 by a spring 28 and when the hoist cage is adjacent the door, a resiliently mounted roller 41 on the cage engages a plate 30 which is pivoted to the frame and which engages the head of the pin 27 to couple the arms 25, 22. Rotation of the handle 21 then causes withdrawal of the bars 10 from the wedges 12. The door may be opened in the absence of the cage for maintenance purposes by inserting a tool in an opening 61 to engage the plate 30 and couple the arms 22, 25 by means of the pin 27. In a modification, Fig. 5 (not shown); the locking bars 10 are replaced by projections pivoted to the door and connected to a sprocket wheel on the shaft 18 by an endless chain.
