Title: Improvements in or relating to high voltage circuit protection arrangements
Inventor: SOSIN BOLESLAW MARIAN
IPC: H02H1/00
Filed: 1965-04-23
Abstract: 1,100,647. Protective arrangements. MARCONI CO. Ltd. 29 Dec., 1965 [23 April, 1965], No. 17312/65. Heading H2K. [Also in Division G1] The fact that overload conditions are occurring in a high voltage line, is transmitted over a radiation link to alarm or safety apparatus, the radiation transmitter being fed by a pulse generator having an operating characteristic dependent on the line condition. In the line to be protected there is inserted a series resistance, the voltage drop across which controls the mark-space ratio of a blocking oscillator T. The oscillator output may be amplified and is applied to an infra-red source, e.g. a GaAs diode, the pulsed output from which is received at a low voltage station by a photo diode detector 10. The detector output is amplified and applied to a Schmidt trigger circuit 12 which passes only pulses above a predetermined amplitude, shaping those that are passed. Connected to the trigger circuit output is a timing circuit 13 (a one-shot multivibrator) and an AND gate 14. The timing circuit is triggered by the trailing edges of pulses from the Schmidt trigger. Under normal line conditions the transmitted pulses representing this condition are sufficiently spaced apart that a timing circuit pulse ends before the next pulse from trigger 12 (Fig. 2, not shown). However, if a voltage overload occurs, the mark-space ratio of the pulse generator rises substantially and a pulse from the Schmidt trigger coincides with a timing circuit pulse, producing an output from the AND gate to actuate the alarm. The device is also provided with a fail safe circuit connected to another output of the Schmidt trigger and providing one input to an OR gate 15, the other input of which is from the AND gate 14. An output from either the AND gate or the fail safe circuit is passed on to a resettable bistable circuit 17 which operates the alarm and/or safety means when over-load occurs. The fail safe circuit comprises a detector 16 and inverting amplifier 20 and gives an output when no pulses are obtained from the detector 10.

Title: An improved manufacture of pour point depressors
IPC: C10G73/04
Filed: 1946-06-12
Abstract: Substances having improved wax-modifying properties, particularly for use as pour-point depressors for waxy mineral lubricating oils are prepared by condensing in presence of a Friedel Crafts catalyst known aliphatic-aromatic condensation products, prepared from chlorinated paraffin wax or corresponding olefins with aromatic hydrocarbons or derivatives, with halogen derivatives of silicon containing 1 or 2 silicon atoms (see Group IV (b)).  The products may be added to waxy mineral lubricating oil in concentrations of .01-5 per cent or may be used in lubricating grease compositions comprising a waxy oil thickened with a grease-forming soap, e.g. calcium stearate, aluminium stearate or sodium, lithium or other metal stearates, oleates or naphthenates.  They may also be used for improving the properties of paraffin wax itself.  Tests are described to show that the products are efficient pour-point depressors and that the depression of the pour-point is more permanent than with untreated aliphatic-aromatic condensation products. Specification 401,341 is referred to.ALSO:Pour-point depressors for lubricating compositions (see Group III) are prepared by condensing in presence of a Fridel-Crafts catalyst a condensation product of a long-chain paraffinic material such as chlorinated paraffin wax or a compounding olefin and an aromatic hydrocarbon or hydroxy or amino derivative thereof, and a substance containing 1 or 2 silicon atoms selected from the group, halogenated silanes, oxygenated derivatives thereof and silicon halides.  Suitable condensation products are described in Specification 401,341.  Suitable silicon compounds are SiCL4, SiBr4, Si2Cl6, Si2Br6, SiHCl3 and SiOCL2.  The condensation with the silicon compound is similar to that used for preparing the starting condensation product, being prepared with a Fridel-Crafts catalyst if desired to a solvent, e.g. tetrachlorethane, or dichlorobenzene.  The preparation of the initial condensation product may be completed by hydrolysis and removal of the catalyst, followed by distillation to remove low boiling materials or the silicon compound may be added to the crude reaction mixture from the preparation of the condensation product, removal of catalyst and distillation being left to the final stage.  The product may be added to lubricating compositions (see Group III).  In the examples: (1) silicon tetrachloride was heated with a chlorinated paraffin wax-naphthalene condensate in presence of aluminium chloride, and after removal of the catalyst, the product was distilled to 600 DEG  F. to remove low boiling materials; (2) chlorinated paraffin wax and naphthalene were reacted in presence of o-dichlorbenzene and AlCl3.  Silicon tetrachloride was added to the crude product and heating continued.  Removal of catalyst and distillation yielded a viscous green oil with good pour-point depressing properties.

Abstract: 1,137,870. Opening crimper filamentary tow. COURTAULDS Ltd. 26 April, 1966 [27 April, 1965], No. 17617/65. Heading D1F. In a continuous process for spreading crimped filaments of nylon, cellulose acetate or polyacrylonitrile, a tow 1 withdrawn from a container 2 passes over guides 3 and 4 and between bars 5, which lay it as a flat ribbon, between bars 6 (at right angles to bars 5) to define the edges of the ribbon and between closely spaced bars 7 (parallel to bars 5) which direct the tow to a stretching zone wherein the crimp is pulled straight without stretching the filaments 1a beyond their elastic limit. The zone is constituted by two pairs 8 and 9 of driven rollers the "fingers" i.e. circumferentially spaced longitudinal ribs or fingers, of each pair of which interengage thereby deforming and "beating" the filaments and, perhaps, promoting an electrostatic charge on the filaments which assists their subsequent separation. The filaments 1b then enter a relaxing zone, wherein the crimps reform thus causing the tow to spread, between rollers 9 and spaced, smoothe.g. rubber-, faced rollers 10 and 11 the former driven at the same peripheral speed as rollers 8 and the latter at approximately 3% increased speed. The width of the spread tow may be varied by adjustment of the relative speeds of the rollers.

Patent GB-679837-A (GB)
Title: Improvements in and relating to the production of translucent material
IPC: C08F257/02
Filed: 1949-07-05
Abstract: Translucent material is obtained by forming a solution comprising a monomeric liquid alkyl or alicyclic ester of acrylic, methacrylic or chloracrylic acid, containing, if desired, some of said ester in polymerized form, and containing up to 2 per cent by weight of a polymer of a monovinyl or monovinylene aromatic compound or interpolymer thereof with one of the above esters, which polymer or interpolymer has a specific viscosity (see below) of not less than 0.06, a different refractive index from that of the polymer of the alkyl or alicyclic ester and is incapable of forming a mixture with the monomeric ester which on polymerization yields a clear solid; and polymerizing the solution to a solid state under conditions whereby a major proportion of the reaction occurs at a reactivity (see below) of not more than 100.  "Specific viscosity" is defined as <FORM:0679837/IV (a)/1> , where ts is the time of flow of a solution of 0.1 gram of polymer per 100 mls. of chloroform in a U-tube viscometer at 20 DEG  C., and tc is the time of flow of pure chloroform.  "Reactivity" is defined as T-1X104, where T is the time in minutes after polymerization has commenced before gelation, as determined by a specific test described.  Preferably the reactivity is from 7 to 20, corresponding to times of gelation of 24 hours and 500 minutes.  Specified liquid esters are methyl, n-propyl, isopropyl and cyclohexyl methacrylates, and they preferably contain 2 to 5 per cent of their polymers.  Suitable vinyl and vinylene aromatic compounds are styrene, chlorostyrenes, vinyl anisole, vinyl naphthalene and chloronaphthalenes, N-vinyl phthalimide, N-vinyl carbazole, acenaphthylene and vinyl fluorene.  The composition of monomer and polymer, freed from air by application of a vacuum, may be poured between two spaced parallel glass sheets and polymerized by heating the assembly in an oven, the glass sheets being then stripped off the polymer sheet.  Or the composition may be flowed on to moving steel bands and polymerized during passage through an oven.  Heat catalysts, e.g. benzoyl peroxide and benzyl hyponitrite, and photopolymerization catalysts, e.g. benzoin, diacetyl, acyloin ethers and a ,a 1-azodiisobutyronitrile, are generally employed. Plasticizers such as dibutyl phthalate and tricresyl phosphate may be incorporated up to 20 per cent by weight of the system.  The products may be shaped or cut up for moulding purposes and are mainly employed for their transmission and filament-hiding power in lighting equipment.  Specification 612,070 is referred to.
