Title: Improvements in or relating to gas fires
IPC: F24C3/04
Filed: 1929-02-23
Abstract: 329,681. McLay, J. A., and Main, Ltd., R. & A. Feb. 23, 1929. Gas fires; radiants.-To obtain a satisfactory distribution of the radiant heat, the radiating surface of a gas fire is concave in vertical section, the upper part, which may be heated to incandescence, facing downwardly. In the fire shown, tubular radiants 1 having a concave central portion are supported against a similarly curved brick back 2, a horizontal section of the concave surface being straight. The radiants are inclined slightly to the rear. The back 2 is formed with side wings 11 which project in front of the radiants, and with projections 13 on the front face, against which the radiants rest. The inner rear faces of the radiants are concave in the vertical direction and are provided with inwardly-directed projections (not shown). Owing to the varying angles at which the hot gases impinge on the walls of the radiants, the points 15 on the rear wall, and the points 16 on the front wall, become more incandescent than the adjacent portions of the other wall, thus causing a variegated incandenscence. The front faces of the radiants may be given various forms, the internal rear faces, which form the chief radiating surface, being however always of the concave form described above. The concavity may be produced by giving the radiants a polygonal, instead of a curved, shape.

Filed: 1972-02-11
Abstract: 1376633 Buoyancy control COMPAGNIE FRANCAISE DES PETROLES and TECHNIQUES LOUIS MENARD 11 Feb 1972 [8 March 1971] 6443/72 Heading B7M [Also in Division E1] A variable-buoyancy tank 11 for raising and lowering an underwater apparatus (see Division E1) comprises a cylinder 138 open at its lower end and having a valve-controlled inlet 61 for the admission of compressed air, and an outlet in the form of a movable tube 37. When the apparatus is at or near the surface of the water, the tank 11 will be substantially full of air and the tube 37 will be in a lowered position. To sink the apparatus a motor 140 is actuated to drive a cable 31 and raise the tube 37 allowing air to escape until the water level within the tank rises as far as the bottom of the tube 37; thus by selecting the position of the tube 37 the apparatus can be submerged to a specific depth. The precise position of the tube 37 in the tank is determined by means of a plurality of optical indicators at a remote point at the surface actuated by switches 44 located adjacent the tube 37 and triggered by a magnet secured to the bottom of the tube. To raise the apparatus the tube is lowered and a sensor 36 on contact with the water causes the valved inlet 61 to open until the water level again coincides with the bottom of the tube. The apparatus may be guided in its movements by engagement with a pair of cables 7, Fig. 13, attached at one end to securing means on the sea bed, and mounted on drums 74 in another open-bottomed tank 8, which is located on the sea bed whilst the securing means are being actuated by a diver. The tank 8 is then made buoyant by a quantity of air from a cylinder 9 and rises unwinding the cables 7. The tank 8 is preferably located at a certain depth below the surface. This depth is predetermined by a screw 14 operating a reducing valve to admit air at a pressure corresponding to the required depth to actuators 75. When the water pressure acting on these actuators 75 equals the preselected air pressure locking members 76 are actuated to grip cables 7.
