Title: Improvements in the production of acetylene by incomplete combustion of hydrocarbons with oxygen
IPC: C07C11/24
Filed: 1955-03-03
Abstract: In a process for the production of acetylene by incomplete combustion of hydrocarbon in the gaseous state with oxygen with the hydrocarbon and the oxygen being separately preheated and the preheated gases being supplied to a mixing chamber which is preferably of circular cross-section, at the inlet end of which they come together with a mean speed of more than 150 metres per second. the mixture then being supplied to a reaction chamber in which the reaction occurs with the formation of a flame, and the products are rapidly cooled, the speed of the hydrocarbon is greater than the speed of the oxygen. Preferably, the ratio of the speed of the hydrocarbon to that of the oxygen lies between the ratio of the densities of oxygen and of the hydrocarbon and the square root of this ratio.  In an example, methane is passed into the mixing apparatus of Specification 672,446 at a speed of 500 metres per second at 600 DEG  C. and 1 atmosphere and the oxygen is fed at 300 metres per second under the same conditions.  A stationary flame is not formed under these conditions.

Abstract: 831,816. Semi-conductor devices. PHILIPS ELECTRICAL INDUSTRIES Ltd. Feb. 26, 1957 [Feb. 29, 1956], No. 6435/57. Class 37. A method of making a device comprising a semi-conductor body with at least one rectifying electrode and an ohmic electrode includes the steps of etching the body and electrode assembly and then introducing it into an atmosphere comprising at least one halogen (excluding fluorine) or a hydrogen halide, and preferably water vapour. In one embodiment an alloy junction transistor, the main body of which is P-type silicon, is etched and then introduced into a glass envelope containing dry hydrogen chloride. The envelope is then sealed, heated to 180 C. and finally cooled. Alternatively moist hydrogen fluoride or moist bromine vapour may be used. In an embodiment comprising an alloy junction transistor the base of which is N-type germanium dry hydrogen chloride is introduced into the envelope, followed by water vapour. In all cases, before finally sealing the envelope, the gas pressure may be reduced to 10<SP>-2</SP> mm. of mercury by pumping.

Patent GB-697351-A (GB)
Title: Improved process for the manufacture of nerve sedatives
IPC: A61K35/12
Filed: 1951-03-19
Abstract: A sedative for all the peripheral nerves is prepared by inoculating or infecting organs or tissues of animals such as cows or rabbits with cowpox, removing the organs or tissues 3 to 10 days after inoculation or infection, dispersing them in an aqueous medium, completely removing protein ingredients from the dispersion, and recovering the sedative, which contains no virus protein or lipoid, from the liquid so obtained.  The aqueous medium is physiological saline solution, water, glycerin water, or a mixture thereof, containing carbolic acid.  In the example, a portion of the testicles or skins of animals is removed 4-5 days after inoculation, well-ground and dispersed in a mixture of physiological saline solution, glycerin and carbolic acid.  The dispersion is alternatively frozen at -5 to -10 DEG  C. and thawed at 15-20 DEG C., allowed to stand, the supernatant liquid decanted and proteins removed in stages by (a) heating to 100 DEG  C. for 1 hour (b) adjusting pH to 5 by the addition of hydrochloric acid and (c) filtering through asbestos treated with sodium silicate and magnesium sulphate.  The filtrate from (c) is treated with kaolin at pH 4.5-4.7.  The absorbate containing the virus and sedative is eluted with N/24-N/26 aqueous ammonia and filtered.  The filtrate is adjusted to pH 7.4-7.8 with N/1 acetic acid, concentrated in vacuo, and the sedative precipitated by the addition of a water-miscible organic solvent e.g. acetone or ethylalcohol.  The effective material can be isolated by cataphoresis of the clear liquid obtained after heating and freezing a dispersion of the tissues in saline solution. Active material may also be isolated from urine of infected animals or from a cowpox inoculated hatching egg.

The bit comprises a body 1 with a tapered hollow shank 3 and four flat faces 2 to enable the head 4 to be firmly gripped, the head having a stem 6 so that it can be mounted coaxially on the body and having the free end face of the shape of a frustum of a cone with the axis eccentric to the axis of the body. The stem 6 is provided with a screen 8 which may engage a spring 7 so as to hold the bit in adjusted position, the body and head being provided respectively with a pin 9 and a number of recesses to engage therewith, after rotation of the head to adjusted position. A rubber washer 16 may be provided round the stem to form a liquid-tight joint between the head and body. In another form, the stem which carries a rubber ring 25 is held in the upper part of the bore of the shank by a washer 18 and screw 17. The head is provided with a number of recesses 24 engaging a spring- pressed pin 19 held in a chamber in the body 1 by a threaded member 22. In either form the pins may be mounted in the head and the recesses in the body and in a further form a number of pins may co-operate with a single recess. The shanks of the electrodes may be smooth so as to be pushed into the sockets of water-cooled holders 10 or may be threaded to screw into the holders. A sheet iron unit may be welded to three angles 13, 14, 15 which cannot be turned in a horizontal plane to accommodate it to fixed electrode bits by adjusting the bits angularly, as shown in Fig. 6.

Void [Abridged as open to inspection under Sect. 91 of the Acts, Sept. 6, 1933]. [Class 83 (iii)] In a horizontal boring, facing, drilling and milling machine having a drilling spindle longitudinally slidable in a sleeve carrying the face-plate, the latter is driven at different speeds by a disengageable drive engaging the face-plate, whilst the boring spindle can be driven independently of the face-plate at different higher speeds or can be connected with the sleeve to be driven from the face-plate. The boring spindle 3, mounted in bearings 4 in the vertically adjustable slide 1, is rotatable and slidable within the sleeve 5 to which the facing head 8 is attached. A change-speed gear box, driven by a motor 9 or by a vertical shaft driven from the base of the machine, rotates gears 11, 12, the former of which drives the spindle 3 through gears 15, 16 whilst the latter drives the facing head through shaft 13 and pinion 17 engaging internal teeth 18 on the head. The gear 16 is displaceable on the spindle 3 to engage a clutch 19 on the sleeve 5 with the spindle, in which case the spindle and head rotate together and the pinion 17 is moved out of gear with the teeth 18 by means of a rack and pinion 20. By moving the gear 16 to an intermediate position or disconnecting the gears 17, 18 either the facing head or the spindle may be rotated with the other stationary.
