Patent GB-778869-A (GB)
Abstract: 778,869. Valves. VAILLANT, H. Feb. 3, 1955 [Feb. 4, 1954; June 2, 1954; June 19, 1954; Sept. 20, 1954; Oct. 30, 1954], No. 3181/55. Class 135. A gas tap mechanism has an axially movable valve operated by press buttons, in which the " On " press button acting on the valve stem is locked in open position by a locking device acting transversely to the valve axis and which is released by an " Off " button movable parallel to the " On " button. Depression of button 69 opens valve 65 and an edge 86, through a lever 87, moves a rod 90 to the left and through an abutment 94 moves a rod 95 to the left to bring an armature 97 into contact with a solennoid 98 and to remove a stop 99 from the ends of two rods 78, 80 which are also moved leftwards by their springs. As shown, the buttons 70, 71, respectively for fully or partially opening a main gas valve 64, are held locked by projections 101, 101<SP>1</SP> on rod 95 entering notches 100, 100<SP>1</SP> in button rods 70<SP>1</SP>, 71<SP>1</SP> respectively. On movement of the rod to the left the projections 101, 101<SP>1</SP> are removed from their notches, but the buttons 70, 71 are still held locked by projections 92, 92<SP>1</SP> on rod 90 entering notches 93, 931 respectively. When the pilot burner 67 is ignited and heats a thermocouple, the solenoid holds its armature 97 so that button 69 may be released until the projection 82 on button rod 69<SP>1</SP> is stopped by the rods 80. The rod 90 moves to the right under spring 91 and unlocks buttons 70, 71. Either button 70, 71 may be locked to hold the valve 64 open by being depressed so that their respective projections 83, 84 engage the bar 78. Should the pilot burner fail, the armature 97 is released and stop 99 unlocks the buttons and allows both valves to close. Both valves may also be closed by depressing button 72 so that projection 85 displaces both bars 78, 80 to the right and unlocks the other stops. In a second embodiment, the button 71 is omitted and one locking bar is controlled by a fluid thermal element. In a third embodiment no thermal control is provided and the buttons are interlocked by a rotary catch. The buttons are shaped as sectors forming a circle and a rotary sprung covered sector housed in the button 72 moves over the button 70 when it is depressed to indicate that the valve 64 is open. In a fourth embodiment only one valve is provided which is locked open by the " On " button engaging the locking bar and closed when the " Off " button is operated to displace the bar. In a fifth embodiment the single valve is operated by a hollow button hinged to the valve stem. On pushing one side of the button the valve is held open by a notch in the button engaging a casing projection. On pressing the other side of the button the notch is disengaged and the valve closed. The projection in this embodiment may be axially movable by a thermal element operated by the pilot burner.

Title: Machine for impelling viscous liquid material e.g. plastics
IPC: B29C48/03
Filed: 1979-11-30
Abstract: The material is impelled within an annular peripheral channel (20) or adjacent channels of a rotor (10) which rotates within the surrounding cylindrical surface (14) of a station (12), to impel the material between a stator inlet (28) and circumferentially spaced outlet (29), against a stationary blocking member (19) which extends into each channel (20) to build up pressure in the liquid which causes it to flow through the outlet (29). Seals to militate against leakage from the channels are provided between rotor and stator surfaces between which there is a narrow clearance (50), the seals comprising oblique channels (26) formed in one of the surfaces, and acting, during rotation between the surfaces, to force the liquid back along the oblique channels (26) into the impelling channel. The leakage pressure, and penetration, along the channels (26) increases between the inlet (28) and the outlet (29). Power loss in driving the rotor is reduced, by a scraper (31) which removes liquid from the bends (27) between the channels (26), at a location of maximum penetration beyond the outlet (29) and of low pressure adjacent the inlet (28). <IMAGE>
