Title: Improvements in and relating to safety apparatus for elevators
IPC: B66B5/22
Filed: 1938-05-11
Abstract: 496,536. Safety catch-gear for mine cages. WAYGOOD-OTIS, Ltd. May 11, 1938, No. 14031. Convention date, July 2, 1937. [Class 78 (iii)] In safety catch-gear for lifts, the appliances which grip the guide rails are arranged between the arms of a U-shaped spring and act to spread the arms of the spring apart on being moved into gripping position. In the form shown, on overspeed of the descending cage, the governor 27 releases the catch 45 and allows the cam grips 33, 34 to retard the rope 21 sufficiently to cause it to pull the levers 48, 55 upwards, thus applying an upward pull to wedges 63, Fig. 2, through the medium of links 62. Initially these wedges slide freely over the rollers 68 until they touch the guides 15, after which the roller - carrying frames 69 move upwards between the wedge - shaped surfaces 80 and in so doing distort the horizontally - arranged arms 115 of the U-shaped spring outwards, thus causing added pressure of the wedges 63 against the guides by reaction. Stops prevent upward movement of the frames 69 beyond a certain limit. When hoisting re-commences, the members 80 are hoisted with the cage, but the frames 69 tend to lag owing to their frictional engagement with the wedges 63. In consequence, the rollers 68 roll down the members 80 and relieve the pressure on the U-shaped springs, so that the wedges are released from the guides, and the frames 69 are restored by their springs 95 to their lowest position. The latching-mechanism 45 is then re-set by hand.

Title: Improvements in or relating to furnaces and processes for the thermal treatment of hydrocarbons
IPC: C07C2/78
Filed: 1954-05-13
Abstract: Acetylene is produced by projecting a flame, formed by the incomplete combustion of hydrocarbons, into a combustion chamber together with a dynamic screen of liquid which is projected along lines parallel to the direction of flame propagation in order to form dynamic walls for the combustion chamber, which walls carry away particles of carbon and prevent their deposition on the fixed walls of the combustion chamber.  A disc-like distributer 1 is traversed by parallel channels 2 through which the mixture of hydrocarbons and oxygen pass and are ignited on entering the combustion chamber 5.  A hollow metal ring 3 with slits 4, along the outer edge of the distributer, directs liquid into the chamber from a duct 6.  Water, injected through means 7, chills the reaction products.  Flashback is prevented by cooling the distributer by passing liquid through pipes 8.  In a modification, Fig. 2, the gas mixture enters an expansion chamber 19, then through a distributer 11 via channels 12 to the combustion chamber.  Liquid from a duct 16, passes to a ring 13 on the edge of the distributer and thence both through slits 14 to form part of the dynamic screen and pipes 18 to a similar ring 131 at the other end of the distributer and slits 141 to form the remainder of the dynamic screen.  Water, through jets 17, chill the reaction products.  The fluid for the screen may be water or a heavy oil.  The chilling water can subsequently be used for preheating the gas mixture.  The liquid screen may be formed on the inner side of a metal sheet or gauze placed inside the chamber, or a metal sheet can be applied directly to the inner walls of the chamber and the liquid screen produced thereon. <PICT:0756606/IV(a)/1> <PICT:0756606/IV(a)/2>
