Abstract: 291,374. Delas, F. X. J. A. May 31, 1927, [Convention date]. Fluids, regulating volume of flow or pressure of.-The speed and volume of a fluid stream flowing between two points where it is kept at predetermined pressures, is increased by cooling the stream at an intermediate point by an amount sufficient to bring the pressure at this point below the pressure at the outlet. In the diagrammatic representation, Fig. 1, saturated steam at constant pressure in a container 1 is passed through a convergent pipe 3, and a cylindrical or slightly divergent pipe 4 to a constant pressure condenser 5. The pipe 4 is cooled by a jacket 7 for the purpose stated above. In the application to turbines, the cooling radiator 18, Fig. 3, may be arranged between the last blade wheel 8 and the condenser, or between stages. In Fig. 4 the cooling is effected by circulating water in a jacket 26 surrounding the annular exhaust duct 24 of a radial flow turbine.

Title: Improvements in television apparatus
IPC: H04N3/08
Filed: 1935-04-25
Abstract: 451,132. Television. SCOPHONY, Ltd., and WALTON, G. W., Thornwood Lodge, Campden Hill, London. April 25, 1935, No. 12490. [Class 40 (iii)] Relates to a television scanning system in which an image of a light source is caused to traverse a surface to be scanned by means of two scanning members, one of which moves at a high and the other at a low speed. The invention consists in the provision of a first optical system which forms two cylindrical images of the light source in separate planes, one image being on the optical surface of the high speed scanning member and having definition in a direction at right angles to the direction of movement of this member, and the second being in some other plane, e.g. on the surface to be scanned or on the surface of the low speed scanning member, and having definition in a direction at right angles to the direction of definition of the first image, and a second optical system which forms or assists in forming on the surface to be scanned a two-dimensional image of the light source from the two cylindrical images. As shown, the lens 4 forms a cylindrical image of the slit 1 on the reflecting surface 10 of the high speed mirror drum 6, the diverging beam from which is focused by the lens 5 so that a cylindrical image of the surface 10 is formed after reflection of the beam from the surface 11 of the low speed mirror drum 7 on the surface 2. The lens 3 is adapted to focus a cylindrical image of the slit on the surface 2. According to a modification, the lens 3 is arranged to focus a cylindrical image of the slit on the surface 11 of the drum 7 and a cylindrical lens 14 is provided which forms a cylindrical image of this surface on the surface 2. The invention may be applied to a scanning system employing oscillating mirrors instead of mirror drums.

Abstract: 1,058,044. Continuous casting machines. KOPPERS CO. Inc. March 24, 1965 [March 26, 1964], No. 12581/65. Heading B3F. In a continuous casting machine means provided to guide and cool the cast slab 15, Fig. 1 (not shown), as it leaves the mould comprises two roller aprons 23 and 33 located one below the other and beneath the mould 17. Each apron is formed in two sections 24, 26 and 32, 34 respectively the sections being positioned one on each side of the cast slab 15. Roller apron 23 includes guide rolls 31 which contact the surface of the slab and are cooled by water spray. The sections 32 and 34 of the roller apron 33 are in the form of recirculatory endless chains of rollers 37 which are water cooled and supported on tracks 39. The movement of the cast slab imparts movement to the roller chains and rotation of the rollers due to friction contact between the slab and rollers. The speed of movement of the slab is controlled by the withdrawal rollers 21. Alternatively, the roller chains may be power driven so as to effect withdrawal of the slab as well as supporting it in which case withdrawal rollers are not required. In order to accommodate cast slabs of different thickness one of each pair of apron sections is adjustable, by hydraulic means, transversely to the passage of the slab 15. Bending and straightening rolls may be provided below the guide roller aprons to direct the strand into a horizontal path.

Abstract: 683,678. Rotary pump. BORG-WARNER CORPORATION. June 1, 1951 [June 16, 1950], No. 13050/51. Class 110(ii) In a gear pump having fluid-pressed bushes at one end, for sealing purposes, radial packing pieces are provided to divide up the external. surfaces of the bushes, the areas between such pieces being subjected to different pressures. In general the area opposite the delivery area within the pump, is subjected to fluid at delivery pressure. The packing pieces may be of metal, plastic material, rubber or neoprene. Fig. 2 shows bushes 32, 33 in which fluid under delivery pressure from the pump outlet 35 passes through a duct 36 to act on segmental surfaces 32a, 33a. Three sealing pieces 40, 41, 42 of U-shaped cross-section restrict the pressure areas with the open or lip portions facing towards the right. Semi-circular plates 43, 44, which are slightly thinner than the packing pieces, prevent lateral. movement of the pieces. The latter may be placed off the vertical axis passing through the gear centres. Fluid leaking past the pieces may be vented to the suction side of the pump through a duct 45. A modification, Fig. 5, uses radial pins 51, 54 provided in V-shaped or otherwise shaped grooves 53 of the pressure-loaded bushes 32, 33, the plates 43, 44 being dispensed with. Fig. 7 shows the use of blade-type seals involving a modification of the housing bore. Blades 61, 62, of rectangular cross-section, are supported by two pairs of half rings 63, 64, which act similarly to the plates 43, 44 in Fig. 2, but prevent lateral movement of the blades in either direction, the pump being reversible. Pair of semi-circular. washer-type springs 65, 66 are provided with each pair of half rings and also load the blades to give initial axial pressure against the bushes and thus against the side of the gears. Fig. 9 shows another modification in which bushes 71, 72 contain packing blades pressed upon initially by springs 84. Bushes 74 contain sealing rings and are pressed laterally by spring 75. Further modifications include spring-pressed circular pistons acting as seals or unitary seals of rubber or the like comprising bushes, Fig. 15 (not shown) having integral, radial sealing blades. The bush areas under different pressures may be greater than two, i.e. there may be three or more segmental areas on each bush. Various cross-sections of packing pieces are illustrated in Fig. 21 (not shown).
