Title: Improvements relating to the treatment of leather
IPC: C14C9/00
Filed: 1955-02-01
Abstract: The water-repellency of leather is improved by treating it with an aqueous emulsion containing the polymerizable fluid intercondensed product of hydrolysis of a mixture composed essentially of 50 to 75 per cent, by weight, of dimethyldichlorosilane 1 to 10 per cent of trimethylchlorosilane, 10 to 35 per cent of methyltrichlorosilane, and up to 10 per cent of a methylchlorodisilane or mixture of methylchlorodisilanes, and a curing agent for such product, comprising a metal salt of an acid, the metal ion being present to the extent of at least 2 per cent of the weight of the hydrolysis product, and the weight of the hydrolysis product being from 0.2 to 20 per cent of that of the aqueous emulsion, and curing the said hydrolysis product. The methylchlorodisilane or mixture of methylchlorodisilanes may comprise dimethyltetrachlorodisilane, methylpentachlorodisilane and trimethyltrichlorodisilane.  A suitable mixture of methylchlorosilanes may be obtained by passing methyl chloride over silicon in the presence of copper at elevated temperatures, as described in Specification 575,667, [Group IV]. Small amounts of other compounds are produced which may be removed before the mixture is hydrolysed.  The salt may be a water-soluble salt of a metal of Group IV of the Periodic Table, e.g. a salt of titanium, zirconium, tin or lead or a complex of such a salt; waterinsoluble salts which are soluble in the methylpolysiloxane hydrolysis product or are dispersible therewith, e.g. zinc or tin octoates or naphthenates may also be employed.  Emulsifying agents such as morpholine oleate, ammonium oleate, sulphonated amide condensation products of fatty acids with organic amines, sulphonated aromatics and mixed alkylaryl sulphonates, sulphonated esters and fatty acid amide condensates may be used in making the dispersions. Stabilizers such as 2-methylpentanediol-2,5 may be added to the diluted emulsions, as used for treatment, to prevent premature breaking thereof, and improve penetration.  Plasticisers, e.g. paraffin oil, paraffin wax, neat's-foot oil, tricresyl phosphate and dimethylphthalate, bonding agents, resins, e.g. polystyrene, polyvinyl chloride, copolymers of vinyl chloride and vinyl acetate and polymethylmethacrylate, and drying oils such as chinawood oil, oiticica oil and linseed oil may be incorporated in the emulsion. Treatment may be by drumming the wetted leather, which may have been pre-treated by drumming it with dilute aqueous ammonium hydroxide, followed by neutralization and rinsing, with the methypolysiloxane emulsion, and then curing by drying, with or without heat.  The leather may subsequently be treated with finishing agents, e.g. alkyl polyacrylate emulsions in conjunction with neutral or synthetic rubber latices, the adhesion of which is improved by priming its surface with organic silicates or partially hydrolysed organic silicates as described in Specification 711,374, [Group III]. Specification 745,154 and U.S.A. Specifications 2,635,059 and 2,635,060 are referred to.

Abstract: 1,131,942. Piezo-electric meters. SIEMENS, A.G. Jan.27, 1966 [Jan.28, 1965], No.3625/66. Heading G1Q. [Also in Division H1] A bending transducer, for use e.g. as the actuating element of a galvanometer, comprises a U-shaped polarized strip of electro-strictive material, e.g. barium titanate, provided on at least one surface with one or more pairs of interdigitated electrodes. Polarizaion is produced by applying the polarization voltage to the interdigitated electrodes as the strip cools from a temperature above the Curie point. This results in alternating zones of opposite polarizaion along the length of the strip. A signal applied to the electrodes results in either expansion or contraction of the surface layer of the strip according to the sign of the signal. If the electrodes and the polarizaion on either side of the strip form mirror images of each other, then signals applied in opposition to corresponding pairs of terminals on either side produce expansion of one side and contraction of the other side of the strip. The Figure shows a U-shaped strip, the limbs of which have been polarized oppositely to each other in such a manner that when the same signal is applied to both limbs, they bend in opposite directions out of the plane of the drawing. The transducer is anchored to a fixed base 17 and a mirror for reflection of a light beam is affixed to the free end.

Abstract: 1,105,099. Measuring rotational speed electrically. SMITHS INDUSTRIES Ltd. Jan. 27, 1967 [Jan. 28, 1966], No.3847/66. Heading G1N.  The rotational speed of the output shaft of an I. C. engine having a coil ignition system is determined by measuring the frequency of the pulses of current in the ignition system. A coil 11 of tape of a square loop, grain orientated, magnetic material is wound to form an annulus, carrying three windings 5, 12, 13, of which the primary windings 5, 12 are connected, one in series with the vehicle battery, and the other with the contact breaker 3, so that the annulus is saturated alternately in opposite directions. The current induced in the secondary coil 13 flows through a meter 16, in series with coil 13, only when the contact 3 is closed because of an avalanche diode 15 connected in series with the meter 16. As the coil 11 is saturated when the contact 3 is closed, the reading on the meter 16 is proportional to the frequency of the pulses in the ignition system and therefore to the rotation speed of the engine. A parallel arrangement of resistor 17 and thermistor 18 is also included in this circuit to compensate for effects of temperature changes.
