Operation:- The parts are in the position shown when the engine is stopped and the throttle is opened by a predetermined angle during starting. During running the manifold vacuum acts (via port 56) in chamber 50 to move diaphragm 46 rightwards until the spring 76 bottoms. The dashpot assembly 66, 58 also moves rightwards and spring 68 maintains the piston 66 with plunger 64 extended until the latter engages lever 38. When throttle 22 is rotated clockwise to a wide open position for acceleration the spring 68 fully extends piston 66 so that when the accelerator pedal is released the spring 40 biases the throttle to move quickly to idle speed position 36. Lever 38 engages plunger 64 moving it leftwards at a speed determined by the air leakage through orifice 70. After the engine stops the decay of vacuum in chamber 50 permits spring 76 to move diaphragm 46 and the dashpot assembly to the left to the position shown.

Title: A method of producing a foamed polystyrene sheet with oriented cell structure,and foamed polystyrene sheet thus produced
IPC: B29C69/00
Filed: 1966-10-26
Abstract: Foamed polystyrene sheets with oriented cell structure are produced by compressing by at least 50% of the initial thickness a foamed polystyrene sheet, while it is in a heat-plasticized condition and with both sides sealed, and then allowing the foamed sheet to expand, thus forming a foamed layer with cell walls which are predominantly directed normal to the sheet and increasing the resistance thereof to compression. The sides of the sheet can be sealed by a covering layer, e.g. paper, fabric webs, metal foil, thermoplastic films, rubber sheets or layers of resin, which may be applied simultaneously with the compression operation and which may remain permanently on the foamed sheet.  The sheet may be heated to a plasticized condition during the compression operation, e.g. by providing the compression elements with heating means.  Said compression elements may comprise pressure rolls, the diameter of the end portions of which are either smaller than the central portion so that the edges of the sheet are less compressed and thus retain their closed cell structure and serve as a lateral sealing of the sheet, or larger than the central portion so that the edges of the sheet are more compressed so as to form a thin compact layer, again laterally sealing the sheet.
