IPC: C01B35/04
Filed: 1935-03-18
Abstract: 440,764. Electrolytic production of metallic borides. SOC. D'ELECTROCHIMIE, D'ELECTRO-METALLURGIE, ET DES ACIERIES ELECTRIQUES D'UGINE, 10, Rue du General Foy, Paris, and ANDRIEUX, J. L., 11, Rue Cornelie Gemond, Grenoble, both in France. March 18, 1935, No. 8446. Convention date, March 17, 1934. [Class 41] Borides are obtained by electrolysis of a fused bath containing boric anhydride or borax, the oxide of the metal whose boride is to be prepared, and a chloride of this metal or of a more electro-positive metal. In the production of alkaline earth or rare earth metal borides, the bath may consist of the borate and chloride of the metal. In the production of borides of other metals, the bath may consist of borates and chlorides of alkali, alkaline earth or rare earth metals together with an oxide or salt of the metal whose boride is to be prepared. For the production of calcium boride, the bath is made up in the proportions 3B2O3, CaO, 7CaCl2. This is electrolyzed at 950‹ C. with current density 50-100 amps. per sq. dem. with a carbon cathode forming the cell lining and a carbon anode. The lower part of the electrolyte containing crystals of calcium boride is drawn off from time to time, and constituents added to the bath to maintain its composition constant. The density of the bath may be maintained below that of the boride by addition of chloride. For the production of titanium boride a mixture of boric anhydride, lime and calcium chloride in the above proportions is prepared and 10 per cent by weight of titanium oxide is added to the mixture. The oxide may be replaced by the carbonate or a halide or by an oxygenated salt of an alkali or alkaline earth metal in which the metal whose oxide is replaced forms part of the acidic radicle. A process in which a fluoride instead of a chloride is employed in the mixture is referred to.

Abstract: 849,128. Magnetic work-holders. SYKES, A. E. June 17, 1959 [March 17, 1958], No. 8463/58. Class 60. A magnetic work-holder comprises a plate or block 10 having means for magnetically holding work thereon and a plurality of plungers 37, Fig. 3, which protrude from the work-engaging face at different parts thereof; in combination with fluid-pressure operated means for securing the plunger in a position in which they make contact with the work. The plate 10 may be flat or may have a profiled working surface contoured to correspond approximately to the shape of a workpiece ; it may be separate or an integral part of a magnetic chuck. The selfadjusting plungers 37 are spring-loaded to bear against the work-piece as it is placed in position and are looked by fluid-pressure to form rigid support so that when the plate is energised the plungers will prevent the work from being distorted at points where gaps exist between the work and the surface of the plate. The adaptor plate 10, Fig. 2, has inserted at spaced intervals transversely extending pole-piece 13 either permanent or electro-magnetic, and a plurality of plunger-receiving pockets 14 arranged in rows and connected by bores 15, alternate bores having linking connections 17 at their outer ends with adjacent bores to provide a continuous pressure channel through the plate from an inlet 20 to the group of plunger sprockets at the remote end. Each plunger 37, Fig. 3, is supported by a spring 41 within a.thinwalled cylinder 34 having flanges 32, 33 pressed into the plate 10. Ring seals 35, positioned by a split cylindrical distance-piece 36, form pressuretight seals. The head 38 of each plunger is surrounded by a flexible washer 39, the periphery of which engages a recess 40 in the mouth of the cylinder. Fluid pressure is applied simultaneously by a screw-jack 26 to the cylinder walls 34 to grip the plungers until a pre-determined pressure is reached, as indicated by the extent to which a spring-loaded indicator 27 projects from a casing 23. Alternative methods of housing and sealing the plungers in the plate are described. In one modification, the spring 41 is omitted, the plunger being moved upwardly by the resilient washer 39 and/or by the attraction of the work-piece for a plunger of magnetic material ; the plunger may alternatively be locked by fluid pressure from within as described in Specification 802,278.

Title: Improvements in photographic processes for combining separately produced sound and picture records
IPC: G03C5/14
Filed: 1930-03-18
Abstract: 350,965. Combined sound and picture films. BRITISH ACOUSTIC FILMS, Ltd., 52, Haymarket, London.-(Assignees of Soc. des Etablissements Gaumont ; 12, Rue Carducci, Paris.) March 18, 1930, No. 8677. Convention date, March 18, 1929. [Class 40 (ii).] A combined sound and picture film, in which the sound record is opaque to ultra-violet rays but is transparent to light within the greater part of the visible spectrum, is made by the following process. A sound record is first made on a film as an ordinary " black-and-white " negative, and from this a print is made on a bichromatized film. After the exposure and development of the print by treatment with hot or cold water and subsequent drying, the bichromate print is either coated with a printing medium which contains a substance opaque to ultra-violet rays (and which may also contain glycerine), or is impregnated with a s olution of such a substance, for example, paranitrophenol in sulphuric acid. According to whether the exposed print has been treated with hot or with cold water, the substance which is opaque to ultra-violet-rays is deposited on the exposed parts or is absorbed by the unexposed parts of the gelatine of the film. Finally the coated or impregnated film is pressed into intimate temporary contact either with the gelatine or with the rear side of a picture film. By this means the said special substance is transferred to the picture film, forming thereon a print of the sound record which is invisible, but from which sound reproduction can be effected by the use of ultra-violet rays. If the sound record is printed on the back of the picture film, a printing medium is used which contains as an additional ingredient a substance such as a solution of trieresylene, which attacks the cellulose acetate or nitrate constituting the film base.

Title: P.C.M. Sampling Circuit.
IPC: H03K19/096
Filed: 1968-02-22
Abstract: 1,151,838. Multiplex pulse signalling; diode gating circuits. INTERNATIONAL STANDARD ELECTRIC CORP. 22 Feb., 1968 [27 Feb., 1967], No. 8761/68. Headings H3P and H4L. In a sampling circuit for a time division multiplex P.C.M system the m input channels are divided into p groups of m/p channels each, the first group comprising channels 1, 1 + p, 1 + 2p &c., the second group the channels 2, 2+p, 2+2p &c., the third group the channels 3, 3+p, 3 + 2p &c. and so on. This ensures that several channel time slots are available for each sampling operation in the groups so that the stray capacitance of the primary sampling gates has little effect. Special low capacitance gates are used for the final multiplexing of the groups. General description.-As shown in Fig. 1, m = 60 and p=3, the primary groups being PG1, PG2, PG3 and the final group SG. Each channel C1 &c. is sampled by operating the associated gate W1 &c., each gate being operated for the duration of three channel time slots and operating in sequence W1, W2 &c. at intervals of one channel time slot. The outputs of the groups are combined in time division by secondary sampling gates SX1 to SX3 controlled by sequential signals X1 to X3 which each occur every three time slots for a duration of one time slot. Secondary sampling gate, Fig. 3.-The input signal, e.g. S1, is supplied to a diode bridge D1 to D4, constant current generators Ga, Gb being controlled by pulses X1 and transistor switches Ja, Jb being closed in the absence of X1. When X1 is present the generators Ga, Gb pass a current which puts the bridge diodes in their high conduction zone so that the stray capacitance is charged quickly by the incoming signal S1. The impedance of generators Ga, Gb is high compared to the input resistance R2 and the signal S1 is transmitted to the output Q with a negligible voltage drop. When pulse X1 is absent the generators Ga, Gb are blocked and the switches Ja, Jb supply a voltage - V, +V to block the diodes.
