Title: Improvements in or relating to pipe moulding machines
IPC: B28B21/30
Filed: 1934-02-08
Abstract: 430,367. Moulding pipes by centrifugal machines. HUME PIPE & CONCRETE CONSTRUCTION CO., Ltd., and STONE, W. L., 1, Buckingham Palace Gardens, London. Feb. 8, 1934, No. 4231. [Class 87 (ii)] A pipe-moulding machine for spinning a series of centrifugal-moulding casings comprises a series of supporting shafts c-c<5>, and driving power is applied at the middle region of the series and is transmitted from shaft to casing and from casing to shaft in both directions to each end of the series. The shafts are mounted in anti-friction roller bearings b and carry friction driving wheels k on which flanged end wheels on the casings are supported. The driving power is applied from a motor d through an infinitely variable speed gear of the expanding-pulley type to a shaft f which is connected by chain gearing f<1>, g<1>, g<3> and f<2>, g, g<2> to the shafts c<3>, c<2> respectively. The shafts are each provided with a grooved track bearing for positioning them on the bearings b. The moulding casings may each consist of a sheet metal shell circumscribed by detachable bands and having at its ends flanged wheels which are retained thereon by longitudinal bolts.

IPC: F15B21/04
Filed: 1954-02-15
Abstract: 746,913. Fluid-actuated valves. DENISON ENGINEERING CO. Feb. 15, 1954, No. 4388/54. Class 135. A surge dampening device comprises a body having inlet and outlet ports 26, 27, a valve 43A, loaded e.g. by a spring 42A acting on a transverse valve pin 42 passing through slots 41 in a cylinder 35, to close a passage from inlet to outlet via a series of ports 40, passage 31 and slots in a cylinder cap 37, and means to control the rate of opening of the valve by inlet pressure including a fluid-receiving chamber 39 with a restricted outlet 45A, opening movement of the valve tending to increase the fluid pressure in the chamber, e.g. via spring 47A and piston 47, and a valve element 46 independently movable in the chamber and in response to the increased chamber pressure to reduce the size of the restricted outlet. Increased pressure in chamber 39 due to an inlet pressure surge acts on the piston 47 to close the valve 46 on the orifice 45A so that the chamber pressure passes only slowly via orifices 52, 45A and passages 53A, 31 to the outlet and valve 43A only opens a few ports 40. When the surge is over, outlet pressure exists in chamber 39 and the piston 47 and valve 43A are moved back to open all the ports 40. In a modification the passage 53A has an opening to the inlet closed by a check valve for relieving outlet pressure.

Title: Absorption refrigeration
IPC: F25B15/04
Filed: 1966-02-02
Abstract: 1,113,182. Refrigerating CARRIER CORPORATION. 2 Feb., 1966 [30 March, 1965]; No. 4675/66. Heading F4H. In a continuous cycle absorption refrigeration system strong solution from the absorber 10 is in simultaneous heat exchange with weak solution and refrigerant vapour from the generator 13 in the rectifier 35. Strong solution is forwarded by a pump 14 to the outer tube 36 of a coaxial heat exchanger in the rectifier, the inner tube 45 of the heat exchanger carrying weak solution which has previously been passed througha coil 47 in an analyser 38. Strong solution from tube 36 is discharged into the top of the analyser, which contains baffles 39, for passage therethrough in countercurrent with rising refrigerant vapour. Condensate from the rectifier also drains into the analyzer at the bottom of which is located a solution reservoir 40 supplying the generator 13 through tube 49. Solution heated in the generator passes to a chamber 53, divided from reservoir 40 by a weir 52, from which vapour passes through space 55 to the analyzer and solution passes through a coil 48 partly submerged in solution in reservoir 40 to coil 47. After passage through coils 47, 45 weak solution is supplied via a restriction 61 and line 29 to the absorber while refrigerant vapour from the rectifier passes through line 58, condenser 11 and restrictors- 24, 26 to the evaporator 27 over which is sprayed a liquid to be. cooled. Vapour from the evaporator passes through line 28 in heat exchange with liquid refrigerant to line 29 for passage to the absorber. In a modification (Fig. 2, not shown) the rectifier (35) is disposed below the top of the analyzer (38) with its axis horizontal. In this case condensate from the: rectifier passes through conduit: (140) to a chamber (141) and weak solution is passed to the rectifier through a coil (147) in chamber (141) instead of through the analyzer. Liquid from chamber (141) passes to the reservoir (40) through a U-tube (142) and vapour returns to the rectifier through conduit (140).

Title: Improvements in methods of and apparatus for picture transmission
IPC: H04N3/10
Filed: 1935-02-15
Abstract: 452,369. Television transmitters. LIPPINCOTT, D. K., 57, Post Street, San Francisco, U.S.A. Feb. 15, 1935, No. 4978. [Classes 39 (i) and 40 (iii)] Scanning is performed by alternately disclosing and occulting complete successive lines across the picture to be transmitted, the disclosing and occulting of each line taking place in the direction of the line. An elon. gated aperture 7, Fig 8, is traversed in the direction of its length across the picture 4( to gradually disclose a complete line so that the signal produced corresponds to the curve 45 and at any point is proportional to the total light in the portion of the line disclosed. This signal is then differentiated (as by passing it through a transformer) to obtain the signal 46 which corresponds to a scanning performed with an infinitely small aperture. The method avoids aperture distortion. As applied to a Farnsworth transmitter, the electron stream corresponding to the picture, is traversed across an elongated aperture 7 Fig. 1, co-operating with an elongated anode 9, and the secondary electrons emitted by the anode are drawn to the shield 6 to produce a current flow through a resistance 14 and inductance 12. Valves 20, 21 have their inputs connected to the inductance 12 and resistance 14 respectively, and their outputs connected in parallel to the resistance 32. The inductance 12 produces the differential of the signal current, while the resistance 14 and valve 21 compensate the voltage drop across the inductance 12 due to its inherent resistance, so that the output across the resistance 32 is the first differential of the current applied to the inductance 12. The return strokes of the aperture are performed quickly and produce a signal across the inductance 32 of opposite sign to the picture signal and this signal is used as a synchronizing signal. At the receiver, the cathode ray tube is biassed so that these signals cut off the ray. The end of the elongated aperture may be square, Fig. 6 (not shown), or curved to produce a signal simulating a cut-off at some given frequency, Figs. 4, 5. As applied to disc scanning, a disc 75, Fig. 9, has elongated apertures 76 adapted to trace adjacent lines on the picture to be transmitted, and a shutter disc 81 cuts off each aperture when it has completely disclosed one line. There are no return strokes to generate synchronizing impulses in this embodiment.
