Title: Improvements in or relating to the production of chlorinated alkyl aromatic hydrocarbons
IPC: C07C17/14
Filed: 1960-05-09
Abstract: Dichloro-derivatives of alkylaromatic hydrocarbons having at least two alkyl radicals wherein a chlorine atom is substituted on two of the alkyl radicals are prepared by a cyclic vapour phase chlorination process which comprises contacting the vaporized hydrocarbon with chlorine gas in the presence of a free radical initiation source which promotes side-chain chlorination to form a mixture of hydrogen chloride unreacted hydrocarbon and mono- and di-chloro-substituted hydrocarbons, passing this mixture to a vaporisation zone maintained at a temperature between the boiling point of the mono- and di-chloro derivatives, recycling the hydrocarbon and mono-chloro-derivatives to the reaction and recovering the di(chloroalkyl)-aromatic compound. In examples, xylene diluted with carbon tetrachloride is chlorinated in a reaction zone illuminated with ultra-violet light to give xylene dichlorides.

Abstract: 1,134,153. Electrodes for semi-conductor devices. GENERAL ELECTRIC CO. 11 April, 1967 [23 Dec., 1966; 13 May, 1966], No. 16449/67. Heading H1K. [Also in Division C7] A SiC crystal has fused to it an electrical lead of pure chromium or of an alloy of chromium with iron and/or nickel containing at least 5% by weight of chromium. The lead is required to be oxidation resistant and ductile, and the brittle range of the chromium/iron system between 25% and 70% by weight of chromium is therefore excluded from the invention. The leads form ohmic contacts to N-type SiC containing nitrogen, and rectifying contacts to P-type SiC containing boron and/or aluminium. Preferred constitutions for the leads are (i) 20% Cr/80% Ni; (ii) 15% Cr/60% Ni/25% Fe; (iii) 11-20% Cr/ up to 12% Ni/up to 2% Mn/up to 1% Si/up to 0À3% C/balance Fe (ie. stainless steels 302, 304 and 420). Suitable pure Cr is produced by iodide decomposition, or by electrolytic means. The leads may be fused to the crystal by heating on a graphite heater in an argon atmosphere. The invention may be applied to electroluminescent diodes or to devices in which incandescence is generated by self-resistance heating with A.C. It is stated to be known to apply to SiC leads consisting of Pt and its alloys with Sn, B or Al, Au alloys with transition metals, pure or doped Si, or W and Mo and their alloys.

A substance is deposited according to a pattern on a semi-conductor wafer by coating the wafer with a light-setting resin, exposing to a positive image and treating the resin so that the unexposed regions are softened and applying the substance so that it adheres to the softened areas. In one example, a silicon wafer comprising a PN junction is provided with a 10Á coating of poly(butanediol-1,4-cinnamylidenemalonate from a solution of this in trichloroethylene sensitized with 0.45% of methyl benzothiazolylidene-dithioacetate. The layer is exposed through a positive mask to a mercury vapour lamp and then heated to 110‹ C. and dusted with a dispersion of impurity material such as a silicate of magnesia + phosphoric acid which adheres to the unexposed areas of the resin coating. Excess powder is removed by washing in decaline and the wafer then subjected to normal diffusion techniques to provide an NPN transistor structure. Instead of heating to 110 ‹ C., softening of the resin may be achieved by turpentine oil. Other lightsetting resins such as poly(vinylcinnamates), poly(diolcinnamylidenemalonates) and poly - (glycol - anthranylmethylmalonates) may be used. Carbon-tetrachloride or methylisobutylketone may be used as softening agents for a resin of poly(tetramethylene - cinnamylidenemalonate). Germanium may be used in place of silicon and the impurities may consist of arsenic, phosphorus and boron.

Class 81(2) The stopper 10, Fig. 1, of an ampoule 8, for an ampoule syringe 1, has a recess 12 for co-operation with a projection 11 on the operating plunger 4 and the projection is narrower than the recess at its tip but broader than the recess at its base, and the length of the projection is greater than the depth of the recess. By this means, when the plunger is thrust forward, the stopper 10 is stretched longitudinally before it is moved forward by the projecting collar on the plunger, and it is thereby drawn away from the ampoule wall except around its rear lip, where it is tightly pressed on the wall by the projection 11. In order to be able to use the syringe for aspirating a hollow plunger rod containing a rod 15, Fig. 6, is used and when the latter is pressed forward, relative to the plunger rod, it thrusts hooked members 20, 21 outwards to engage the rubber stopper.

Motor power plant.-In friction clutches, applicable for driving blowers from electric motors and turbines or other prime movers, of the kind having a pair of conical members moved apart by engagement with right and left hand screwthreads on the driving-members, the motion is opposed by spring pressure and' is limited by a stop to limit the power transmitted. The driving- shaft 2 carries right and left hand screw-threads 14, 15 engaging clutch parts 11, 12 slidably connected by teeth 16 and supported on a collar 18. The part 12 carries a brake-drum 17, and when the brake is applied rotation of the shaft 2 moves the parts 11, 12 into engagement with the clutch parts 9, 10, respectively secured to member 3 on the driven shaft 1 and to a drum 5 connected to the member 3 by bolts 6 and springs 7. Increase of load produces axial movement of the parts 3, 5 until the drum 17 contacts with a stop 19 on the shaft 2, when further increase of load produces slip. The arrangement permits over-running of the shaft 3. A clutch such as described may be applied at either end of the driven shaft 1 so that a. blower may be driven normally by an electric motor at one end of the shaft and by a turbine or other prime mover at the other end, a starting-valve on the turbine &c. being kept normally closed by pressure from the blow until the electric motor fails or is cut out.
