Patent GB-801128-A (GB)
Title: Dehalohydrogenation of halohydrocarbons
IPC: C07C1/26
Filed: 1956-10-05
Abstract: In a modification of the preferred process of the parent Specification, wherein contaminated catalyst is withdrawn from the reaction zone, stripped of absorbed hydrocarbons and halohydrocarbons, contacted with air or steam at a temperature at which carbon is oxidized and returned to the reaction zone, there is introduced into the reaction zone a volatile hydrocarbon or halohydrocarbon at a rate to utilize as heat of vaporization the excess heat generated in the exothermic dehalohydrogenation reaction, thereby to maintain the temperature substantially constant in the reaction zone.  Preferably, the contaminated catalyst is contacted with a stream of air in the regeneration zone at a temperature of from 350 DEG  to 550 DEG  C. maintained by the controlled introduction of liquid water into that zone.  Lost cuprous halide catalyst is preferably replaced at least periodically by introducing into one of the zones through which the catalyst passes metallic copper, a copper salt or copper oxide.  Advantageously, the reaction product is fractionated to separate dehalohydrogenation products from unchanged feed material and the latter is recirculated, but most advantageously the crude reaction product is mixed with a polyhalohydrocarbon to be supplied to the reactor and the mixture is fractionated, dehalohydrogenation products being recovered and the remaining mixture recirculated.  Forms of apparatus suitable for effecting the process are described with the aid of drawings.  In examples: (1) trichlorobenzene is converted to o-, m- and p-dichlorobenzenes, monochlorobenzene and benzene by the process of the invention with hydrogen at 500 DEG  C., this temperature being maintained by the controlled introduction of liquid benzene into the reactor; (2) a crude mixture of 1:2:4- and 1:2:3-trichlorobenzenes and 1:2:3:4- and 1:2:4:5-tetrachlorobenzenes is similarly converted to the same products as in (1); (3) a mixture of o- and p-dichlorobenzenes similarly gives monochloro-benzene and benzene. Reference is also made to comparative experiments using catalysts of reduced copper content and using catalysts of copper halide on alumina-silica gel, silica gel, diatomaceous earth and pumice. References, similar to those in the parent Specification, are also made to other dehalohydrogenations which may be performed by the process of the invention.

Patent GB-1465515-A (GB)
Title: Detector
IPC: G01R31/11
Filed: 1974-07-10
Abstract: 1465515 Leak detectors SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ BV 8 July 1975 [10 July 1974] 30495/74 Heading G1N A cable comprising two insulated parallel conductors separated by ferromagnetic material with a predetermined Curie point is laid over a cryogenic container, whereby leakage of cryogenic material changes the magnetic material from paramagnetic to ferromagnetic, producing a local impedance discontinuity which is located by sending a voltage pulse along the cable and determining the time taken for the reflected signal to return to the sending end. If the discontinuity is small, only a corresponding proportion of the transmitted pulse is reflected and the remainder continues along the cable to locate other discontinuities and the end of the cable. If a discontinuity is large, a permanent magnet can be located at the cold area to saturate the magnetic material and reduce its permeability again, thus removing the effect of the discontinuity. Alternatively the voltage pulse can be sent first from one end then the other end of the cable. A number of such cables can be associated with a container using an automatic switching system to feed a pulse to the cables from each end, cyclically. The system can be used to detect a hot spot producing a local impedance change by converting the magnetic material from a ferromagnetic to paramagnetic state, or to locate a fault in the cable itself. Suitable types of cable and ferromagnetic materials are described.

Abstract: 391,049. Type-bar-making machines. VOGT, H., 61, Bendestorf, Wilhelmsburg, Harburg, Germany. Oct. 31, 1932, No. 30536. [Class 100 (iii).] Assembling matrices ; spacers.-In a type-barmaking machine having an assembler-shoot buffer comprising a guard having lateral members which are moved into such a position over the assembler entrance as to form abutments for rebounding matrices and prevent them from leaving the assembler, the guard consists of a U-shaped wire spring which is movable about its transverse member between the rigid shoot covering plate and the matrixguiding tongue, the free ends of the spring being bent up to form the abutments for the rebounding matrices. The matrices are delivered by the assembler belt 1 to a slideway 2 forming a shoot which deposits them in front of a star-wheel 6 whereby they are pushed into and aligned in the assembler 7. A guiding tongue 3, pivoted at 4 to the shoot covering plate 5, is deflected by the passing matrices for which it acts as a brake. The covering plate 5 also carries the guard which consists of a U-shaped wire spring 9, pivoted to the plate 5 by its transverse member 10, and having its parallel sides bent to form elbows 11 which normally support the guard on the tongue 3. When the tongue 3 is deflected by the travelling matrices, the guard 9 is moved to the position shown in dotted lines where the bent up ends overhang the assembler and form resilient abutments for rebounding matrices. The plate 5 further carries a straight rigid finger 14 which projects into the path of delivered spacing wedges 12 and serves to guide them into the assembler. The edge of the wedge which strikes the finger is rounded off and smoothened to diminish wear of the finger.

Title: Improvements in or relating to organosilicon compositions and to the treatment of porous and fibrous materials
Inventor: MARSHALL HEDLEY SAMUEL BOWDON
IPC: C08L83/08
Filed: 1960-09-07
Abstract: An organosilicon composition for waterproofing porous and fibrous materials (see Division D1), comprises an organic solvent solution or aqueous emulsion of a mixture and/or a reaction product of a cyanuric halide and an organosilicon compound having at least one organic substituent containing a hydrogen atom capable of reacting with the cyanuric halide with elimination of hydrogen halide.  The organosilicon compound can be a silane or siloxane containing at least one functional radical linked to Si preferably through at least 2 C atoms, e.g. an aminopropyl, N-methylaminopropyl, aminobutyl or hydroxybutyl radical, the remaining valencies of Si being satisfied by alkyl, alkenyl, aryl or halo-hydrocarbon radicals or H atoms. Reaction occurs on mixing the reactants in the presence of a base, e.g. an alkali metal carbonate or hydroxide, or, preferably, an amine, and the preferred proportions of the reactants are such that only one of the halogen atoms of the cyanuric halide is replaced by the organosilicon compound. In examples the compounds are formed in situ from cyanuric chloride and various aminoalkyl siloxane-dimethylsiloxane co-polymers. Specification 680,265 is referred to.ALSO:Porous and fibrous materials, e.g. wool, cotton, nylon, rayon and silk, are rendered water-repellent by treatment with a mixture and/or reaction product of a cyanuric halide and an organosilicon compound having at least one organic radical containing at least one H atom capable of reacting with the cyanuric halide with elimination of hydrogen halide (see Division C3).  The organosilicon compounds used are silanes and siloxanes containing, as the preferred reactive substituents, aminopropyl or aminobutyl radicals.  The treatment may be effected (1) by pretreating the material with a base, e.g. an alkali metal carbonate or hydroxide or an amine, and drying, followed by impregnation with an organic solvent solution of the organosilicon compound and cyanuric halide, with subsequent drying, steaming, washing and further drying; (2) by the above pre-treatment followed by impregnation with an aqueous emulsion of the reactants, with subsequent washing and drying; and (3) by impregnating the material with an organic solvent solution or aqueous emulsion of the organosilicon compound, cyanuric halide and the base, with subsequent drying. Examples are given of the treatment of cotton pieces by the above processes.  Specification 680,265 is referred to.
