Abstract: 969,953. Pressurized heating systems. PRESSURISATION Ltd. Nov. 11, 1960 [Nov. 11, 1959], No. 38177/69. Heading F4U. A pressurization unit for a closed circuit heating system comprises an expansible and contractible over-spill tank 1. The latter is mounted on a frame structure 2 which accommodates a high pressure vessel 3 and pumps 4 and 5, a cylinder 10 of compressed nitrogen being mounted inside or outside said frame. Spill liquid due to expansion in the heating system and vessel 3 is stored in tank 1 in the space between the walls of the tank and a bellows 11 having its upper end secured to inwardly turned flanges on the side walls of the tank and its lower end closed by a metal plate 12 which carries hollow metal balls 13 acting as floats. The tank cover 14 is removable and is provided with a vent 15 communicating the interior of the bellows to atmosphere. Leakage and evaporative losses are made up through a mains inlet 16 controlled by a float valve 26, which opens the inlet at a predetermined minimum liquid level, and an overflow chamber 19 with a float operated outlet is provided. At all stages of expansion and contraction of the tank only a small constant amount of air is contained in the tank, aeration of the liquid being thus minimized. Liquid is supplied to the tank via conduit 23 through a pressure controlled solenoid valve 6, an alternative path being provided in the event of failure of the latter through a spring-loaded relief valve 6a. On contraction of the liquid in vessel 3 pumps 4 and 5 are automatically brought into operation to return liquid to the said vessel via conduits 23 and 24. The pumps are arranged to operate in tandem, one cutting out as the predetermined working pressure is approached and the other then operating to " top-up " the pressure as and when required.

[Classes 7 (ii) and 7 (iv).] Contacts, arrangement of external ; preventing unauthorized use.-A bimetallic thermostat acting through an electromagnet is used for breaking the battery circuit when the engine stops. The circuit is reset for starting by a lock-switch d, the turning of which causes a cam disc e to depress a switch-rod f. A collar f<2> on the rod bridges spring blades in the battery-coil circuit. Contacts p, p<1> in the same circuit are closed only by the cam disc e when the lock is completely turned. A finger projecting from the rod f engages beneath the armature g of a solenoid g<1>. The bimetallic element h is encircled by a heating-coil h<1> in the battery circuit. If the ordinary ignition switch is allowed to remain closed when the engine stops, the coil h<1> is sufficiently heated to bend the element h, thus closing the contacts h<2>, energizing the coil g<1> and withdrawing the armature g<1> from retaining the switch rod f in the switch-closing position. The lock d may be dispensed with, the rod f merely protruding through the front of the casing. An additional electromagnet j may be used to shortcircuit the thermostat when the dynamo is in use.

Title: Improvements in processes of isotope-separation by reflux electromigration of moltensalts
Inventor: CHEMLA MARIUS
IPC: B01D59/42
Filed: 1959-11-17
Abstract: 887,052. Separating isotopes electrolytically. COMMISSARIAT A L'ENERGIE ATOMIQUE. Nov. 17, 1959 [Nov. 24, 1958], No. 38937/59. Class 41. In the separation of isotopes by electromigration using molten salts, the fusion temperature of the salt, e.g. a lithium halide, is reduced by adding another salt having the same anion, and the mobility of the cation is near to that of the cation isotopes to be separated. The anion evolved is circulated back to the cathode compartment, and migrates to the anode. The process is effected in a cell dividing the catholyte 2, Fig. 1, from the anolyte 1 by a diaphragm 3, e.g. of zirconia grains. Both electrolytes consist of a mixture of lithium bromide and potassium bromide containing 30% of the latter, by which the fusion temperature of the lithium salt is lowered by 150‹ C. to about 500‹ C. Bromine evolved at the carbon anode 4 passes as a condensate to a reservoir 7 from which it is re-vaporized in a boiler 9 and is fed into the cathode compartment 2. Excess bromine passes out through a pipe 12. The vaporization is at a controlled rate operated by an auxiliary heater 15. Details are given of the change in ratio of isotope concentration after 12 to 30 days.

Title: Non-blocking link-access switching system
IPC: H04Q3/00
Filed: 1958-12-05
Abstract: 898,704. Electrical calculating-apparatus. STANDARD TELEPHONES & CABLES Ltd. Dec. 5, 1958 [Dec. 10, 1957], No. 39308/58. Class 106 (1). The invention relates to an auto-patch system for interconnecting lines individually with one another with no possibility of blocking through absence of idle paths. The apparatus described uses a link-access switching system so arranged that all the lines can be in use at the same time. The system is described as applied to a computer in which connections are set up and broken down according to a programme. A trunking system using cross-bar switches is used, generally of the automatic telephone type except that there is no limit on the proportion of lines in use at any one time. Source lines SL000-SL479 and receiving lines RL000-RL479 are divided respectively into 24 switching groups of 20 lines each. Each group is connected to the horizontals of primary and secondary switching stages such as PG1, SG1. Each switching stage comprises a pair of associated cross-bar switches with 20 horizontals and 40 verticals. One of the verticals V is used for verification and the others are connected to links extending to separate link group switching stages LG1-LG39. Each of these stages comprises two associated cross-bar switches forming cross-points for 24 verticals and 24 horizontals. Switch controller 800 receives information for the setting-up or breaking-down of a connection from code receiver 700, which is controlled by tape reader 500 or manual controller 600. In setting up a connection controller 800 marks match control conductors MC extending between the primary and secondary stages, a group of primary-operate conductors PO and a single hold conductor between the primary stage and the link stage, all according a preference allotter of the telephone exchange type. The link path preference varies from group to group. In breaking down a connection it is sufficient to release the hold conductor. Failure to make the desired connection, as indicated by a verification test, results in the preference allotter being advanced and the desired numbers remaining in store. The controller then makes a further attempt and a fault indicator 900 shows the progress made. Repeated attempts are made until success is achieved or until the manual controller 600 instructs otherwise. The manual controller may be used to try to establish the connection, cleardown of controller 800 having resulted from the intervention. Alternatively the unsuccessful connection may be abandoned and the rest of the programme continued. U.S.A. Specification 2,577,067 is referred to.
