Abstract: 955,720. Semi-conductor switching circuits. SIEMENS & HALSKE A.G. March 24, 1961 [March 24, 1960], No. 10881/61. Heading H3T. A three state switching circuit comprising a pair of switching devices each having a respective negative resistance element connected across its input, is characterized in that a control voltage having three levels can be applied to switch the state of one, or other or neither of the negative resistance elements. In Fig. 3, tunnel diodes D1, D2 are biased into their low voltage region in the absence of a signal Ust so that both transistors T1, T2 are cut off and no signal reaches load R3. If terminal a is made positive with respect to terminal b by a signal Ust sufficiently large to switch diode D2 to its high voltage state, transistor T2 will conduct to feed current from source U4 to load R3. If the polarity of Ust is reversed, transistor T1 conducts feeding current from source U3 to load R3, this current being in the opposite sense to that from U4. In a modification, Fig. 4, separate loads R4, R5 are used for each transistor, and the two transistors may then be of the same conductivity type.

Title: Improved polythene compositions
IPC: C09D123/06
Filed: 1945-05-03
Abstract: A composition for the production of solid films on surfaces comprises a paste-like dispersion of polyethylene in a solution of one or more normally solid film-forming materials dissolved in a volatile liquid of one or more components, of which at least the higher boiling component or components are capable of dissolving the polyethylene only at an elevated temperature at atmospheric pressure, the film-forming materials being in an amount of from 2 to 50 per cent by weight of the polyethylene and being capable of forming solid solutions with polyethylene.  The polyethylene may be dispersed mechanically in the form of a fine powder or a solution of it in a fraction of the volatile liquid may be added, hot or cold, to a solution of the film-forming material in the remainder of the solvent.  Films are obtained by evaporating a part of the solvent at a temperature greater than 60 DEG  C.  Suitable volatile liquids are benzene, toluene, xylene, tetrahydronaphthalene, petroleum ether, chlorobenzene and trichloroethylene.  Chloroform or carbon tetrachloride may be added as a diluent.  Suitable film-forming materials include poly-styrene, hydrogenated polystyrene, halogenated polythene, polyisobutylene of molecular weight greater than 60,000, rubber, cyclized rubber and synthetic rubbers such as those known as "Neoprene," "G.R.S.," and butyl rubber.  Modifying ingredients, which together with the film-forming material amount to 5 to 30 per cent by weight of the polyethylene, may be added and may be chosen from rosin, gum elemi, ester gum, hydrogenated castor oil, paraffin wax, microcrystalline wax, ozokerite, carnauba, ceresin or montana wax, beeswax, or polyisobutylene of molecular weight less than 60,000. Dispersing agents such as "Lubrol" (Registered Trade Mark) or an aluminium soap may be added together with dyes and pigments.  The compositions may be used to coat paper, cardboard and woven fabrics and the inside of chemical containers; in bonding such materials to give moisture-proof products; and for making chemically resistant pipes and tubes.

Abstract: 1,031,331. Lubricating systems. EATON MANUFACTURING CO. March 17, 1964 [March 28, 1963], No. 11293/64. Heading F2A. [Also in Division G1] A metering device for a lubricating system comprises a metering-piston 22 (Fig. 1, not shown) and a pair of valve-pistons 44, 46 slidably lodged in cylinders 18, 16 which are inter-connected by passages 30, 32, pressurized lubricant being fed alternately to inlets 24, 26 in cylinder 16 to effect reciprocation of the pistons and expulsion of lubricant to a bearing through an outlet 28 at the centre of cylinder 16. The motion of the piston 22 is detected by visual-indicating means 10 mounted at one end of the cylinder 18. Said means may comprise a screw-threaded hollow member 62 (Fig. 2, not shown) made of a non-magnetic material and containing a permanent magnet 96 slidably lodged in a recess 90. When the piston 22 approaches the means 10, the magnet 96 is drawn towards a portion 108 of the piston which is made of a magnetic material. The magnet carries a coloured indicating-element 98 which can be seen through a transparent dome or bonnet 74. A compression-spring 92 is provided to bias the magnet away from the piston. In a modification (Fig. 3, not shown), the indicating means comprises a permanent magnet 148 carrying a slidable coloured-indicating-element 152 engaging with a transparent bonnet 132 which contains a liquid 158 having a colour distinct from that of the element. When the magnet is drawn towards the piston, the element is covered by the liquid. In further modifications (Figs. 4, 5, not shown), the magnet 200, or 242, carries an indicating element 204, or 246, having a plurality of coloured lands 206, or 248, which periodically register with either opaque or transparent areas 192, 194, 250, or 252 in a bonnet 182, or 230, when the magnet reciprocates in response to the motion of the piston 22. In another modification (Fig. 6, not shown), the magnet is replaced by a slidable member 324 made of a magnetic material which is attracted by a permanent magnet 334 attached to the metering-piston 332. In yet another modification (Fig. 7, not shown), the upward displacement of a magnet 424 is limited by a shoulder 428 on a coloured indicating-element 426 abutting a guide 414.

The copolymer may be cross-linked, e.g. by vinyl crotonate, glycols or diamines, and may be hydrolysed by any suitable agent, e.g. water, inorganic basic hydroxides and inorganic and organic acids, either in situ or before addition to the alcohol.  The alcohol which is gelled is any monohydroxy alcohol which will form a suitable gel and which has good burning properties, and aliphatic alcohols up to dodecanol are mentioned. Mixed alcohols, e.g. methyl and ethyl, are also suitable.  Water may be present as a diluent in amounts up to 40 wt. per cent, and up to 10% of other combustible fuels, e.g. hydrocarbons, such as benzene, petrol and mineral spirits, may also be present.  The pH of the composition may be raised, e.g. to a value of 6 to 9, by the addition of any alkaline agent, e.g. NH4NH3, OH, NaOH, KOH, alkyl amines, alkanolamines and diamines, suitable amines being mentioned.ALSO:Hydrolysed copolymers of maleic anhydride with low molecular weight olefins (e.g. ethylene, propylene, butylene, isobutylene), which copolymer may be cross-linked by vinyl compounds, e.g. vinyl crotonate, glycols or diamines, and which are useful as gelling agents for alcohols, are prepared by hydrolysis of the copolymer by any suitable agent, including water and water-alcohol mixtures, basic inorganic hydroxides, and organic and inorganic acids. In examples, the mixture is usually heated, e.g. to 90 DEG  C., and an amine is occasionally present during the hydrolysis.
