Title: Improvements in and relating to surgical casts or the like
Inventor: MAY GEORGE
IPC: A61F13/04
Filed: 1951-08-02
Abstract: A stiffening bandage comprises two settable fabric layers, preferably embodying cellulose acetate thread, with a reinforcing structure of cord between them.  The inner layr of fabric is softened with a suitable solvent, such as acetone, and applied to the limb, the cord structure, which may be as a spiral, a net or in parallel lengths, is wound round this and the outer fabric layer, similarly softened, is applied over the whole.  Either the cord incorporates threads of material similar to the fabric or a suitable adhesive is used, so that it will adhere to the fabric layers and, on evaporation of the solvent, a rigid structure is obtained.  The cord structure may be attached to the two other layers by stitching if desired. Specification 677,133 is referred to.

Title: Electrical alarm or circuit breaking devices
IPC: H02H3/33
Filed: 1965-04-30
Abstract: 1,106,423. Transistor circuits. BASSANI S.p.A. 30 April, 1965 [19 Dec., 1964], No. 18352/65. Heading H3T. [Also in Divisions H1 and H2] In the event of earth leakage the current induced in the secondary winding 10 of a corebalance transformer 1 biases a transistor 12 to conduction and direct current from a battery 14 commences to flow through the emitter-collector circuit of the transistor, an auxiliary primary winding 11 of the transformer and an alarm or tripping device 13. The current in the winding 11 produces a positive feed-back, increasing the E.M.F. of the coil 10 and reducing the resistance of the transistor until the core of the transformer becomes saturated. Then current is no longer induced in the winding 10 and the transistor ceases to conduct. If the device 13 is merely an alarm device, the cycle of operation would repeat, but if the device 13 is the trip coil of a circuit-breaker, then the opening of the circuitbreaker contacts terminates the operation of the system. A potentiometer 15 and rectifier 16 provide a charging circuit for the battery 14, and a thermistor 17 provides ambient temperature compensation.

Abstract: 665,512. Statistical apparatus. REMING- TON RAND, Inc. July 12, 1949 [Sept. 15, 1948], No. 18430/49. Class 106 (i). In a connection unit for a record card-controlled machine comprising three frames supporting push-rods 33, Bowden wires and plungers 34 respectively, each rod 33 has wire-receiving wells. As shown in Fig. 1, the unit is used in a tabulator as described in Specification 555,823, for transmitting the movements of pins 25, which sense the 90- column card shown in Fig. 7 and act on corresponding rods 33, to permutation bars 32, each actuated by a corresponding plunger 34. The three supporting frames are separate from one another and bolted together. Each rod 33 is grooved at its upper end and has a similarly grooved plate 53a, Fig. 4, secured to it to form four wells 53. The plungers 34, arranged in rows each carried by a separate removable frame section 46, pass through diagonal slots and have widened lower ends to be engaged by up to three wires. Fig. 6 shows an arrangement for translating the forty-five column card code of Fig. 8 into the ninety-column code of Fig. 7. A push-rod 33b representing an even digit, when actuated, engages the push rod 33a representing the next lower odd digit and also lifts a lever 78 by a stud 77, the lever then engaging a stud on and thus lifting the " nine " rod 33a. U.S.A. Specification 2,354,549 also is referred to.

Title: Improvements in electrical generators
Inventor: WATTON RONALD
IPC: H02K21/16
Filed: 1954-06-23
Abstract: 774,195. Permanent magnet generators. PRINCIPAL SECRETARY OF STATE FOR FOREIGN AFFAIRS. July 20, 1955 [June 23, 1954], No. 18458/54. Class 35. An electrical generator comprises a wound salient pole stator and a rotor having a plurality of radially-extending permanent magnets each provided with a pole piece, the pole pieces being separated by gaps. Referring to Fig. 2, the rotor comprises six permanent magnets 6 seated on the faces of a hexagonal portion of the rotor shaft 2, and each magnet is provided with a pole piece 8 of rhombic shape. A disc 12 of diameter equal to the outer diameter of the pole pieces and of material of good conductivity, such as copper or brass, is pressed on to the shaft 2 on either side of the hexagonal portion and the discs are connected together by six copper tubes 14 which pass through the spaces between adjacent magnets and into apertures in the discs 12 where they form good electrical contact with the discs. Each pair of adjacent copper tubes together with the parts of the two discs between them form a loop of high conductivity surrounding one of the magnets; in consequence of these loops the mechanical effort required to turn the rotor varies comparatively little with the electrical load. The rotor may be completed by potting with a suitable plastic, such as a synthetic epoxy resin, which fills all the interstices including the gaps between adjacent pole pieces. The short-circuited loops may be arranged around the pole pieces instead of around the magnets; thus the gaps between the pole pieces may be filled with a non- magnetic metal instead of potting resin. The generator may be hand- or foot-operated, the rotor being operated through gearing from a pair of handles or pedals.

Patent GB-1019653-A (GB)
Title: Improvements in and relating to the purification of silicon compounds
IPC: C08F10/00
Filed: 1963-05-10
Abstract: SiHaXb, wherein X is a halogen, a and b are O or an integer from 1 to 4 and the sum of a + b is 4, is purified by contact with free bromine or iodine to form high boiling point halogen-impurity compounds which are then separated. Separation may be effected by distillation.  The impurities may be arsenic, phosphorus, boron, and/or sulphur.  The process conditions are not critical, other than that the contact is effected at a temperature below the decomposition temperature of the silicon-containing material, preferably at its boiling point, so that it can be continuously removed by distillation from the halogen-impurity compounds which remain in the residue.  Distillation at atmospheric pressure is preferably employed.  Elemental bromine, or iodine, or alternatively, halogen-containing compounds which release either one of them, e.g. potassium iodide, may be used. The use of an excess of free iodine or bromine is preferred. In a typical example, trichlorosilane containing 200 p.p.b. (parts per billion) As and 9 p.p.b. P was distilled at atmospheric pressure at 32 DEG  C. in a quartz column having one theoretical distillation plate.  Iodine crystals were added to the distillate, which was redistilled. Separation of the halogen-impurity compounds may also be effected by selective adsorption or differential diffusion through a membrane or porous medium.  Silicon may be produced from the purified silicon-containing compounds by thermal decomposition.  The silicon and purified silicon-containing compounds may contain less then 1 p.p.b. As and less than 1 p.p.b. P.ALSO:As and P impurites in a sample of SiHaXb (where X is halogen, a and b are 0-4 and a+b=4) are analysed by separating the high boiling halogen-impurity compounds from the sample and determining the amount of As and P in said compounds e.g. colorimetrically.  The SiHaXb is contacted with free bromine or iodine to form the high boiling point halogen impurity compounds which are then separated e.g. by distillation, selective adsorption or differential diffusion through a membrane or porous medium (see Division C1).  Elemental bromine or iodine, or halogen-containing compounds which release either one of them. e.g. KI, may be used.

Abstract: 121,631. Featherby, H. G. Dec. 18, 1917. Projectile fuses. -Relates to percussion fuses for bombs, of the kind in which a transverse safety-bolt or pellet is held until a vaned member has made a predetermined number of rotations. and is thereupon moved out of the path of the firing-pin by a spring. According to the invention, the spindle of the vane device or " propeller " is made solid with the firing-pin, so that, on impact, a blow is transmitted directly through the spindle to the firing-pin. In the construction shown, the vaned spindle c, which carries the fir- Ing-pin n, passes through a, sleeve f held by a spring and by a shearing-wire h. Screwed on the upper end of the spindle c is a bush j, which normally engages with a safety-bolt l lying in the path of the firing-pin n. As the bomb drops, the spindle c, rotated by its vanes, screws the bush j down so as to release the bolt l, which is then ejected by a spring m, the fuse thus becoming armed. To delay the arming, the boss of the propeller " may be screw-threaded upon the spindle, so as to travel up it before beginning to turn it. A removable safety-cover e is provided.
