Title: Improvements in or relating to combustion apparatus
IPC: F23R3/12
Filed: 1947-06-16
Abstract: 623,977. Generating combustion products under pressure. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. June 16, 1947, No. 15798. Convention, date, June 24, 1946. [Class 51 (i)] In a gas turbine plant, in which the annular combustion chamber is defined by conical walls and has an annular series of nozzles 37 in its up-stream end wall, the primary air is admitted from the surrounding air duct in a manner to produce vortical movement about the axes of the nozzles. Fig. 3 is a cross-section of the combustion chamber looking up-stream. In the inner and outer walls 31, 32 of the chamber there are longitudinal rows 38, 39 of perforations for admitting air which are located opposite alternate spaces between the nozzles. The air passing through them produces vortical movements in opposite directions about adjacent nozzles. Single rows of perforations may be used in place of the double rows shown.

Title: Improvements in the removal of water from lower aliphatic acids and anhydrides and from other organic liquids
IPC: C07C51/46
Filed: 1932-06-06
Abstract: Ethylidine chloride is employed for the removal of water as vapour from organic liquids such as aliphatic acids and the anhydride mixtures obtained by the thermal decomposition of such acids.  The aqueous organic liquid may be mixed with ethylidine chloride and distilled in a column still, the ethylidine chloride layer of the condensate being returned to the still.  If dilute acid is to be treated, it may be first concentrated by a known extraction method up to for instance 70 per cent strength.  In the treatment of anhydride reaction mixtures, the ethylidine chloride may be injected into the hot reaction vapours, the conditions being such that the anhydride, and preferably also the acid, condenses; or the reaction vapours may be led below the surface of a body of ethylidine chloride or be made to impinge upon the surface of a stream of ethylidine chloride, the water vapour being carried away by vaporization of ethylidine chloride, while the anhydride and acid condense.  The ethylidine chloride may be used alone or in admixture with other liquids such as light paraffins, gasoline, kerosene, benzene, benzene homologues, ethers, and mixtures of ethers with petroleum hydrocarbons.  An example describes the treatment of acetic anhydride reaction vapours. Specification 320,606, [Class 2 (iii), Dyes &c.], is referred to.ALSO:Ethylidine chloride is employed for the removal of water as vapour from organic liquids such as acetic propionic or other aliphatic acid or the mixtures of acid and anhydride obtained by the thermal decomposition of aliphatic acids.

Abstract: 1,073,279. Metal pouring ladles. UNITED STATES STEEL CORPORATION. April 14, 1965 [April 21, 1964], No. 16116/65. Heading F4B. Apparatus controlling movement of the stopper rod 24 in a ladle comprises a cross-bar 26 attached to said rod by a joint 43 and reciprocable vertically by an hydraulic motor 28 on guide rods 67 mounted on an inverted L-shaped framework 36 attached by pins 66 to brackets 62 on the ladle outer wall, said framework also carrying a pump and control system 30, an auxiliary pump and control system 32, a fluid reservoir 78 and a locking mechanism 34. The control system 30, Fig. 6 (not shown), comprises an electric motor-driven pump feeding fluid from the reservoir 78 either to a high-speed system or a low-speed system each incorporating a four - way three position, solenoid-operated valve and a variable orifice flow control valve. The motor and the solenoidoperated valves may be operated by pushbuttons on a panel or control may be completely automatic subject to the level of molten metal in a mould. The auxiliary control system 32 incorporates a fluid reservoir 146, a manually operated pump 148 and a valve operated by a normally-open solenoid blocking communication with hydraulic motor 28 until a failure occurs in the electric power. Locking mechanism 34 which is used to hold the stopper rod 24 in a closed position during pouring of molten metal into the ladle and during transportation, comprises an operating rod 170 with turnbuckle 172 and a manually-operated handle 174. The joint 43 incorporates a cylindrical sleeve 44 attached to cross-bar 26 and flanged split bushings 46 and 48 with eccentric bores so that the stopper rod 24 may be positioned accurately over the pouring nozzle 22.

Abstract: 562,585. Seats. CHAPMAN, A. W. Nov. 13, 1942, Nos. 16119/42, 17972/42 and 6519/43. [Class 52 (ii)] In a seat or chair of the slung canvas type, a supporting member for the occupant's thighs (or back or head) consists of a pivoted and detachable member mounted on the front transverse seat-supporting rod (or upon the transverse back-supporting rod) and arranged either between the upper and lower canvas runs of the seat (or the front and rear canvas runs of the back) or externally of the canvas with its rear (or bottom edge) resting on the canvas. The pressure of the occupant's thighs or back or head adjusts the angular position of the supporting member. As shown in Fig. 1 as a thigh support for use with a canvas seat of the endless band type, the thigh support 1 comprises a curved structure of sheet metal, wood or plastic material, having a series of holes 8 ... 13 in its sides to receive selectively a pivotal rod 14 which may be passed through holes in the supporting brackets 15. The endless band 16, 17 constituting the seat may be passed over the rod 14, as indicated by broken lines, to take up sag. Further adjustment may be effected by passing the lower strand of the endless band over a spare rod 19 which may be inserted in vacant holes 8 ... 11. In a modification, Fig. 4 (not shown), the holes 8 ... 13 are dispensed with and the thigh support is slotted at the sides to hook over the pivot rod 14. Instead of the pivot rod 14, side studs secured by nuts may be used. The upper strand 16 of the endless band instead of passing directly over the thigh support may first be passed under and round the rod 19 located in the holes 13. Instead of an endless band, a single strip may be used. As shown in Fig. 3, the thigh support 23 hooks over the front bar 24 of the seat and the flexible band passes through slots 25, 26 therein. In further modifications, Figs. 5, 6 and 7 (not shown), the thigh support is secured to the front rod of the seat by spring clips or by string, the rear edge of the support resting on the canvas. In a further modification, Fig. 8, the thigh support 45 rests on the canvas seat and hooks on to the front rod 48. In a further modification, Fig. 10 (not shown), the thigh support is of complete box section enclosing the front rod of the seat and lying between the two strands of the endless band. To constitute a support for the back, neck or head of the user, the device is placed on the top back-supporting rod of the seat.
