Filed: 1939-08-28
Abstract: 534,230. Incandescent electric igniters. WHITE, E. Aug. 28, 1939, No. 24712. [Class 7(iv)] The electric circuit supplying an incandescent igniter is automatically broken with rise of temperature. In Fig. 1 the outer part 13 of the conductor 13, 131 is supported by a U-spring 17. On starting a branch circuit B energizes an electromagnet 29, drawing down the limb 20 and closing the gap between the parts 13, 13<1>. Current flows through the circuit A until the rising temperature of the tube 6 supporting the part 131 draws the latter away from the upper portion 13. A perforated screen 9 of refractory material surrounds the tube 6. In a modification, the tube 6 and branch circuit B are not used, and the parts 13, 13<1> are united ; increased temperature is relied on to separate the end 22 from the tube 6.

Patent GB-1097805-A (GB)
Title: Method for manufacturing para-chlorophenol
IPC: C07F9/12
Filed: 1966-06-06
Abstract: A monochlorophenol containing a preponderating proportion of p-chlorophenol is prepared by converting phenol into triphenyl phosphate, chlorinating the triphenyl phosphate with elementary chlorine and hydrolysing the product to remove the phosphate group. The hydrolysis may be effected with acid or alkaline reagents, some of which are specified, at atmospheric or raised pressure.  Examples are given.  Triphenyl phosphate for use in the process may be obtained by (1) reacting phenol with phosphorus trichloride, suitably at 70-150 DEG  C. in a solvent, e.g. toluene, xylene or halogenated benzene, to yield triphenyl phosphite, which is then oxidized, e.g. with hydrogen peroxide, nitric oxide, sulphuric acid, persulphuric acid, vanadium oxide or barium peroxide, to yield triphenyl phosphate; or (2) reacting phenol with phosphorus oxychloride at 60-200 DEG  C. without a solvent but in the presence of a catalyst, e.g. aluminium chloride, magnesium chloride, zinc chloride, phosphorus pentachloride or magnesium oxide.  Chlorination products of triphenyl phosphate, for use in the process, are prepared by treating triphenyl phosphate with elementary chlorine either in the absence of a solvent at a temperature above 110 DEG  C. or in the presence of a solvent, e.g. acetic acid, carbon tetrachloride or carbon disulphide, at - 10-100 DEG  C.  In either event, a chlorination catalyst may be present, e.g. ferric chloride, aluminium trichloride, antimony chloride, phosphorus chloride, sulphur chloride, bromine, iodine, sulphur, active carbon or activated clay.

D., and WILSON, J., Triplex Works, Eccleshall Road, King's Norton, Birmingham. Sept. 11, 1933, No. 25170. [Class 56] A method of forming a coherent foraminous mass of glass, silica, or other vitreous material, consists in packing a ring of vitreous material with elements which are regular in size and shape, and then heating the mass until incipient fusion takes place and the elements become united to one another along their contacting surfaces. The resulting porous mass may be used as a filtering layer, as a packing for gas-washing apparatus, or for ornamental purposes. The Figure shows a glass ring 11 packed with elements 12 consisting of pieces of glass tube of narrow bore. The assembly is placed on a sheet of asbestos and is heated until the tubes 12 become fused to one another and to the ring 11. Glass balls or beads may be used instead of the tubes 12, and the ring 11 may be of conical or other shape to form a removable diaphragm for use in chemical apparatus.

[Also in Group XI] A device, especially for medical work, for suspending a unit such as an X-ray tube or an operation lamp, comprises a number of flexible carrying members which only withstand tensile stresses and to which the unit is secured at a number of fixation points, and support means to which the other ends of the members are connected, adapted to alter the effective length of the carrying members, the carrying members being so arranged as to restrict motion of the centre of gravity of the unit to a surface having a downwardly-pointing peak at the position occupied by the centre of gravity of the unit when it is at rest. As shown in Fig. 2, a body 1, supporting, e.g., an X-ray tube, is suspended from points E, F, G, H in the ceiling by cords or wires 2, 3, 4, 5 and 2<SP>1</SP>, 3<SP>1</SP>, 4<SP>1</SP>, 5<SP>1</SP> fixed to the body at A, B, C, D.

The cords may be connected to drums 13 on a carriage 10, Fig. 3, which carriage runs by wheels 9 on tracks fixed to the ceiling, or to another carriage running on ceiling tracks at right-angles to the first-mentioned tracks. A motor 14 on the carriage drives by chain gear a worm spindle 16, which engages four worm wheels 15. Each wheel 15 is connected to a shaft 21 carrying a drum 13, on which two cords are wound. Arms 24, 25 connected to nuts engaging oppositely threaded portions of each spindle lay the cords evenly on the drums 13.
