Title: Improvements in clock movements
IPC: G04C15/00
Filed: 1957-12-20
Abstract: 857,200. Electric clocks. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 20, 1957 [Dec. 31, 1956], No. 39746/57. Class 139 In an electric master clock having an auxiliary reserve drive a synchronous electric motor 18 normally drives the seconds shaft 30 through gearing 23, 24, 26, 31. The mainspring of the auxiliary drive may be wound by the synchronous motor 18 or by another motor and the balance is normally mechanically locked by a detent toggle mechanism 55 controlled by a solenoid 22 connected in parallel with the motor 18. If the supply fails the solenoid 22 is de-energised and the detent mechanism moves with a snap action to free and impulse the balance so that the mainspring drives the shaft 30 through the gearing 37, 38, 40, 42, 31. A cam 67 rotated by the mainspring closes a switch 20 every minute so that the synchronous motor drive can only take over on the minute. The clock drives a program tape which is sensed by a set of brushes carried by a bracket normally held in operative position by the plunger of a solenoid connected in parallel with the motor. The solenoid is de-energised during a supply failure to allow a spring to move the bracket and so withdraw the brushes from the tape.

Title: Improvements in or relating to the production of high-strength inorganic materials
Inventor: CALOW CLIFFORD AUBREY
IPC: C22C47/14
Filed: 1964-10-01
Abstract: Metal materials of higher tensile strength than that of the bulk material in which ultra thin fibres of metals and refractory materials are incorporated in a matrix of the material in such a manner that they are aligned in the direction of the maximum stress the bulk material is to withstand are produced by forming a thread or tape of an organic material in which are dispersed fibres of a metal or of a refractory material and a finely divided metal powder, the fibres being aligned parallel to the length of the thread or tape, rolling, wrapping or laying the tape or thread on suitable formers, removing the organic component of the tape or thread, e.g. by ignition after drying, and applying heat treatment, e.g. firing, preferably under pressure, to the residual metal matrix containing the aligned fibres.  The fibres may consist of silicon nitride, silica, aluminium oxide or tungsten.  The diameter of the fibres is preferably not greater than 3 microns, and they may be coated with a metal, e.g. nickel, the thickness of the coating being only about 0.1 micron.  The organic component of the thread or tape may be alginic acid, a cellulose derivative or a polymeric resin.  In an example, 0.5 vol % of silicon nitride fibres 1 mm long and 4 wt % of silver powder of particle size less than 1 micron are dispersed in a 2% by weight aqueous solution of ammonium alginate and the dispersion extruded through a slot-shaped orifice into aqueous hydrocloric acid of pH 1.  The resulting gel tape is picked up on a cotton belt, wound on to a drum, washed with water and dried at 70 DEG C. under vacuum.

Title: Electrical converter comprising at least one group of parallel-connected controlled semi-conductor rectifiers
IPC: H02M1/088
Filed: 1964-10-05
Abstract: 1,073,346. Protecting controlled rectifier circuits. ALL MANNA SVENSKA ELEKTRISKA A.B. Oct. 5, 1964 [Oct. 8, 1963], No. 40465/64. Heading H3T. [Also in Division H2] In an electrical converter, in which controlled semi-conductor rectifying elements are grouped for parallel operation, each group comprises two or more elements in parallel and is connected in series with a non-linear reactor arranged to saturate only when all the rectifying elements of the group are conducting. The inductance of the reactor therefore remains high until all the elements of the group are conducting and thereby prevents overload of whichever element of the group fires first. Fig. 1 shows an arrangement in which corresponding elements (e.g. 1 and 7) in three-phase bridges I and II operate in parallel and each phase R, S, T includes a saturable reactor 20, 21, 22. Devices 14-19, such as linear reactors, divide the load current equally between the parallel rectifying branches. In an alternative arrangement (Fig. 2, not shown) each branch of the bridges I and II may comprise a group of parallel-connected rectifying elements (28-31), the group being in series with the load winding (32) of a saturable reactor. In this alternative arrangement, as the branches carry D.C., a source (34) and bias winding (33) are used to provide a flux in the saturable reactor in opposition to that produced by the load current.

Title: Process for condensing and polymerizing furfuryl alcohol and the intermediate or partial condensate thereby obtained
IPC: C08G65/36
Filed: 1961-11-13
Abstract: A process for condensing and polymerizing monomeric furfuryl alcohol to a stable intermediate stage comprises heating a body of furfuryl alcohol to a temperature sufficient to effect volatilization of the monomeric furfuryl alcohol, contacting the monomeric furfuryl alcohol vapours with activated alumina containing at least 50% by weight of gamma alumina, and removing the liquid product of the intermolecular condensation reaction from contact with the activated alumina. Water formed during the reaction may be continuously removed as vapour, and the liquid product may be mixed with the body of furfuryl alcohol being heated. The body of furfuryl alcohol may be heated until the boiling temperature thereof indicates the complete elimination of monomeric furfuryl alcohol. Water and monomer vapours from the catalyst zone may be condensed and separated, the water being discharged to waste and the monomer recycled to the heating zone. The process may be effected in a plurality of heating and catalyst zones. The alumina is preferably granular and may be activated by heating at 700 to 1100 DEG F. The products may be used in preparing foundry moulds and cores.

Title: Process for the manufacture of arylsulphochlorides
IPC: C07C303/08
Filed: 1960-11-24
Abstract: Anhydrous aryl sulphochlorides are obtained by reacting an aromatic compound with chlorosulphonic acid by a method in which the chlorosulphonation mixture is run, while stirring, into a mixture of water and a water-immiscible organic solvent that is inert towards the sulphochlorides, the organic layer is separated and, when it contains water, the water is removed by means of a dehydrating agent or by azeotropic distillation, and if desired the aryl sulphochloride is isolated from the organic solvent.  The water may be used in the form of ice.  The chlorosulphonation mixture may be obtained by reacting benzene, naphthalene, or an alkyl or alkoxy compound thereof, or a halogen, amino, or nitro derivative thereof, with chlorosulphonic acid, if desired in presence of a halogenating agent such as sulphuryl chloride, phosphorus trichloride or pentachloride, or thionyl chloride, or in presence of an alkali metal halide.  As inert solvent there may be used benzene, nitrobenzene, chloroform, carbon tetrachloride, ethyl or butyl acetate, di-isopropyl ether, methyl ethyl ketone, tetrachloroethane, or tetrachloroethylene. Examples describe the production of acetylsulphanilic acid chloride, and 5 - chloro - aniline - 2,4 - disulphonic acid chloride. Reference is also made to the production of para-toluene sulphochloride, para-nitrobenzene sulphochloride, and alpha- or beta-naphthalene sulphochloride.

Title: Gaslight accumulators
IPC: H01M10/52
Filed: 1975-10-06
Abstract: A gas-tight electric accumulator with aqueous electrolyte contains within its case (9), on the one hand, a recombination arrangement (6) in which the hydrogen and oxygen gases produced during operation of the accumulator are recombined to form water. On the other hand, the accumulator case (9) contains an arrangement (10; 1,2 with 12) from which hydrogen or oxygen can be output under control. The output takes place whenever the gases developed during operation of the accumulator have an unstoichiometric composition. The arrangement can be a solid substance (10) which emits gas, for example, when the pressure is lowered or the temperature is increased. The arrangement can also be formed by connecting together an inert auxiliary electrode (12) and a main electrode (1; 2) for generating one of the gases, the connecting-together being effected by a pressure-dependent switch (11). Due to the recombination, it is easier to keep the electrolyte level in the cell constant and, in addition, the risk of explosions is greatly reduced. <IMAGE>
