Abstract: 1,165,072. Thermal storage heaters. G. BAUKNECHT G.m.b.H. ELEKTROTECHNISCHE FABRIKEN. 16 Aug., 1967 [16 Aug., 1966], No. 37662/67. Heading F4U.

Abstract: 989,031. Gas-blast switches. WESTINGHOUSE ELECTRIC CORPORATION. Oct. 5, 1962 [Oct. 12, 1961], No. 37691/62. Heading H2B. A gas-blast switch comprises a metallic tank 2 supported on an insulating column 3, a pair of terminal bushings 5, 6 extending into the tank and supporting fixed contact structures 7, 8 which define exhaust chambers 27, 28 communicating with hollow conductors 30 in the bushings, movable contacts 16 for interconnecting the stationary contacts and mechanical actuating means 13, 68 extending through the insulating column 3. In the arrangement of Fig. 3, the movable contacts are carried by a tubular member 24 extending through a highpressure gas reservoir 23, the tank 2 containing the gas e.g. sulphur-hexafluoride, at a lower pressure. When the movable contacts 16 are opened by the actuating means through rack and pinion gearing 11, 12, 13a, a spring-loaded detent 51 opens a pilot valve 46 to open a blast valve 43. Gas flows from the reservoir 23 through the valve 43, the member 24, ports 37 in a tubular contact guide 40, through the fixed contacts 7, 8 into the chambers 27, 28 and thence through the hollow conductors 30, filters 31 and the bushings to the tank 2. Movable insulating guides 25 direct the blast gases into the fixed contacts as described in Specification 963,931 and arcing electrodes 58 and resistors 63 are provided. In an alternative arrangement, Figs. 5-8 (not shown), the fixed contact structures are vertically arranged and the moving contact assembly is formed as a U-shaped bridging member.

Title: Improvements in and relating to the chilling of foodstuffs and the like
IPC: F25D3/10
Filed: 1956-12-11
Abstract: 850,377. Cooling foodstuffs; refrigerating. MORRISON, W. L. Dec. 11, 1956, No. 37891/56. Class 29 Material such as unwrapped or wrapped foodstuffs is chilled in an insulated, portable storage container 1 by liquid refrigerant, e.g. nitrogen, evaporating in contact therewith at atmospheric pressure, the evolved gas being withdrawn, reliquefied and returned to the container. Vapour from compressor 22 (which may be multi-stage with intercoolers), flows through oil filter 26 and coolers 28, 30, 35 cooled respectively by returning vapour, an evaporator 32 of another system and returning vapour. The cooled vapour flows through an expansion device 37 liquefying in part and flows into tank 2 whence the liquid flows through pipe 3, cooler 5, controls valves 7, 49 and auxiliary receiver 9 to the container 1. Vapour evolved therein flows through pipe 11a, heat exchanger 5, heat exchange coils 14, 17. and booster pump 20 to the compressor. A gas storage vessel 23 to compensate for varying loads is disposed in the suction line. Part of the gaseous refrigerant from cooler 30 flows through expansion engine 43 and oil filters 45 to an intermediate point of heat exchange coil 14. Vapour from receiver 2 enters coil 14 through pipe 39. Make-up refrigerant can be introduced into received 9 through valve 10. On starting up a valve 50 in pipe 11a is operated to vent gas from the container 1 so that no air enters the refrigerant circuit, the valve being thereafter actuated to forward the gas to coil 14. In a modification, Fig. 3, liquid from receiver 2 flows through pipe 61 to a container 79 in which a constant level is maintained by float valve 80, the liquid being supplied to container 1 by pipe 78. Evolved gas passes through concentric pipe 77. bubbLes through the liquid in container 79 and flows through pipe 11a and then a heat exchanger coil in the liquid in receiver 2. Pipes 77, 78 are fitted to a hood 75 applied to container 1 and liquid from spray pipes 76 falls on to a pad 74 placed on top of the goods 73 and drips on to them. The vapour has to pass through the pad to reach the vapour pipe 77.

Title: Improvements in or relating to modulation systems
IPC: H04N5/40
Filed: 1938-12-31
Abstract: 523,353. Modulating systems. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Dec. 31, 1938, No. 37999. Convention date, Dec. 31, 1937. [Class 40 (v)] In an absorber type of modulator the load and absorber are both connected in parallel with the output terminals of a line which is substantially equal in length to an odd number of quarter wavelengths and is fed from the carrier source. The impedance of the absorber is varied in accordance both with modulating potentials and carrier voltages taken from the load end of the line. As shown, the line L connects the carrier generator G of approximately constant voltage to the load R 2 . The absorber valves 54, 55 have their anodes connected in pushpull to the output of the line by the transformer 56, 57, and their grids are controlled in parallel through sub-absorber valve 46 and sub-sub-absorber valves 36, 37, by modulation voltages from transformer 39, amplified in valve 41. Condensers 50, 51, 52, 53 impress radio-frequency voltages on the grids of valves 54, 55, to aid their power-absorbing capabilities ; resistances may also be included in the anode circuits to dissipate some of the power. Valves 36, 37 have the radio-frequency voltage from the end of the line L impressed in push-pull on their grids by the couplings 34, 35, are biassed beyond cut-off, and in the unmodulated condition are only made conductive by the peaks of the radio frequency voltages. As the conductivity of valves 36, 37 increases, the power absorbed by valves 54, 55 increases, and due to the impedance-inverting effect of the line this results in a decrease in the power supplied by the generator and a decrease in the voltage on the line. Thus a state of equilibrium is reached, the modulation varying the bias of valves 36, 37, and the radio-frequency voltage on the line, which is in effect modulated, adjusting itself so that it is always just sufficient to cause anode current flow on the peaks. The load R 2 , which may be an antenna or a transmission line, may have an impedance other than the surge impedance Zo of the line L; also the line L may not be exactly an odd number of quarter wavelengths long. The load may also be coupled to the line by means of an amplifier, Fig. 4 (not shown). In Fig. 5 (not shown) the source of carrier is a valve oscillator followed by an amplifier; but any suitable source may be used.,

Title: Polyvinyl chloride
Inventor: MATTHEWS RICHARD JOHN STRACHAN
IPC: C08F114/06
Filed: 1958-11-28
Abstract: The invention claimed is polyvinyl chloride having a density greater than 1,406 and less than 1,424.  The Specification states that such polyvinyl chloride may be prepared by polymerizing vinyl chloride at -20 DEG  to 60 DEG C. using a redox catalyst comprising a tertiary hydrocarbon hydroperoxide, an iron compound capable of producing ferrous ions in the reaction medium, and ascorbic acid or a lactone thereof.  The reaction may be carried out in a common solvent for the monomer and catalyst, e.g. methanol or ethanol, or in aqueous dispersion containing an "antifreeze agent", e.g. methanol, ethanol, glycol or glycerol, and an emulsifying agent.  Suitable hydroperoxides have one of the formulae X-R1 CR2-OOH or HOOO-R1 CR2-X-R3 CR4-OOH where R1-4 are C1-C4 alkyl groups and X is an aromatic group. Suitable iron compounds are ferrous sulphate, ferrous ammonium sulphate and ferrous chloride.  The vinyl chloride may constitute 20 to 50 vol. per cent of the reaction mixture, the hydroperoxide 0,05 to 0,15 wt. per cent of the vinyl chloride, the ascorbic acid 75 to 300 molar per cent of the hydroperoxide and the iron compound 0,001 to 0,02 wt. per cent of the vinyl chloride. Some or all of the catalyst components and/or the monomer may be added in increments as the reaction proceeds.  The molecular weight of the product may be kept relatively low by using a chain-stopping agent such as bromo and/or chloro methanes. Preferred products have a softening point (B.S.I.) above 100 DEG C. Examples illustrate polymerization in aqueous dispersion using a mixture of C10-18 mono-alkyl sulphates as emulsifier and in methanol solution. Reference has been directed by the Comptroller to Specification 895,153.

Another new pallet is then picked up by the trolley as it rises to the loading position. Several loading lines in parallel may feed, by separate trolleys (41), Fig. 3 (not shown,) a common conveyer (43).
