Title: Process and apparatus for heat transfer between media at different pressure levels
IPC: G21D9/00
Filed: 1969-07-08
Abstract: 1279864 Nuclear power plant RHEINISCHE BRAUNKOHLENWERKE AG 8 July 1969 [8 July 1968] 34465/69 Heading G6C In a high pressure helium cooled nuclear reactor power plant, the helium flows through a heat exchanger, of which the secondary fluid is lead which penetrates any leakage in the heat exchanger surface, to seal the helium flow circuit. The reactor, 9, is cooled by the helium gas flow, 1, through the heat exchanger, 13. Lead is introduced into the exchanger through the pipe, 14, from the storage vessel, 12. If a heat exchanger pipe fractures, the leak is sealed by a flow of liquid lead into the lower part of the helium circuit, the exchanger, 13, being positioned so that the lead pressure is greater than that of the helium. In a modification, the helium flows through the exchanger tubing which is immersed in the liquid lead.

To prevent reversal during discharge and over-charge during charging, each cell of a battery is connected in parallel with a semiconductor diode having a characteristic as shown in Fig. 3, whereby the diode conducts at negative cell voltages (portion A, B) and at positive cell voltages above a threshold value (portion C, D), and is substantially non-conductive over the normal discharge voltage range (portion B, C). By a suitable choice of diode the slope of portion A, B and shape of portion B, C can be varied to suit individual requirements, Fig. 4 (not shown). The application of the invention to sealed or unsealed lead-acid, silver-zinc or nickel-cadmium cells is discussed, in which a number of similar or dissimilar diodes are series-connected across the cell to match the normal value of the charged cell voltage.

Filed: 1927-12-21
Abstract: 292,423. Aldrich, L. K. Dec. 21, 1927. Sheet-separators; pile supports.-In connection with an automatic sheet-feeding machine in which the top sheet is separated and forwarded by means of a suction separator 4, or in any other manner, a sheet-holding device is provided for preventing double feed and to prevent the sheet below the top one from creeping towards the front of the pile support. The sheet-holding device is preferably a tapered rubber member 15 adjustably secured in an L-shaped arm 13 pivoted at 11 in a support. 6 carried by a rod 8 mounted in the end of a lever which is reciprocated vertically or oscillated about a horizontal axis by a part of the feeding-machine, such as the lever which operates the table-raising gear. In the downward movement of the support 6, the holder 15 engages the second sheet after the top one has moved past it, as shown in Fig. 2, and then the pivoted arm 13 moves rearwardly so that, as shown in Fig. 3, the second sheet is pressed against the rear wall 5 of the pile support, which thus serves to keep the top sheet registered accurately and prevents creeping of the sheets. A stop 20 limits the return movement of the arm 13.

Steering-gear. -In a load-carrying body or a trailer of a motor road vehicle of the type having its rear end mounted on a bogie having dirigible wheels the bogie comprises a transverse frame member mounted to swing about a vertical axis relatively to the vehicle and having mounted on it for oscillation about a transverse axis a structure carrying road wheels some of which are dirigible. In the construction shown the vehicle frame 1 is connected by a turntable 5, 6 to a transverse member 7 having independent trunnions 9 for longitudinal beams 8 mounted at each end on pairs of road wheels 10. The rear pairs of wheels are mounted on stub axles 11 which are steerably pivoted at 12 in the beams 8 and carry arms 13 connected by pivoted links 14 to arms 15 fixed to a central pin 16 rigid with the vehicle frame 1. Thus, when the frame 1 turns relatively to the bogie frame 7 the rear wheels 10 are steered relatively to the bogie. The dirigible wheels may also be steeled by hand when desired, as, for instance, when the vehicle is being backed, and for this purpose the pin 16 carries a worm-wheel engaged by a transverse worm 17 which may be rotated by means of hand-wheels 20 and gearing 19.

Title: Method and apparatus to effect reactions in an automatic manner
IPC: B01J19/18
Filed: 1961-09-29
Abstract: 989,424. Automatic control of gas-liquid reactions. M. BALLESTRA. Sept. 29, 1961 [Oct. 5, 1960], No. 35121/61. Heading B1X. A method for automatically affecting reactions between a liquid reactant and at least one gaseous or vapour phase reactant comprises feeding a previously proportioned amount of liquid reactant to a reactor and then feeding a gaseous or vapour phase reactant to the reactor, the feeding of the latter reactant being terminated by a weighing device sensitive to the total weight of the reactor and its contents. The weighing device may be calibrated to control the inlet valve for the gaseous or vapour phase reactant and also to control the discharge valve of the reactor when the total weight of the reactor and its contents indicates the completion of the reaction. In a preferred embodiment the reactants are alternately introduced into a second reactor so that the flow of the gaseous or vapour phase to one or other of the two reactors is continuous. As shown in Fig. I liquid reactant is supplied through valve 2 into proportioning vessel 3 in predetermined quantity controlled by weighing device 4 and is then fed via valve 6 into reactor 8. Valve 6 now closes and gaseous or vapour phase reactant enters via valve 15 until the reaction is completed, this being determined by weighing device 12. Valves 7, 16 and 25 of reactor 9 resting on weighing device 13 operate in an identical manner to valves 6, 15 and 24 and while reactor 8 is being charged with gaseous or vapour phase reactant, reactor 9 is emptied of reaction products and then fed with liquid reagent prior to receiving the gaseous or vapour phase reactant. Reactor 8 will then discharge its reaction products and then be supplied with more liquid reagent. In Fig. 2 (net shown) an additional neutralization reactor is provided for the sulphonation products of alkylbenzenes, alcohols, sulphonates and olefinic compounds using sulphur trioxide. It is stated that additional proportionating vessels 3 may be used when more than one liquid reactant is used.

Abstract: A method of fluorinating benzotrichloride and its alkyl and chloro-substitution products by halogen exchange consists in reacting these compounds or one of their partially fluorinated derivatives in vapour or liquid form with sodium, barium or potassium fluorosilicate at temperatures exceeding 200 DEG C. Catalysts which may be used in the process are iron powder, anhydrous ferric chloride and aluminium chloride.  Silicon tetrafluoride produced in the process may be reconverted into fluorosilicate in the known manner and reused in the process of the invention.  In examples:  Benzochloride-difluoride and benzotri-fluoride are obtained by reacting benzotrichloride vapour with sodium fluorosilicate (1); the chloride-difluoride obtained in (1) is converted to trifluoride by a similar process (2) and a mixture of compounds in which one, two and three chlorine atoms on benzotrichloride are replaced by fluorine atoms are obtained by heating sodium fluorosilicate, benzotrichloride and iron powder (3).
