Title: Copolymers useful for the surface processing of synthetic paper
IPC: C08J7/044
Filed: 1972-06-30
Abstract: 1403237 Copolymers for the surface processing of synthetic paper MITSUBISHI PETTROCHEMICAL CO LTD 30 June 1972 [1 July 1971] 30859/72 Heading B2E [Also in Division C3] Copolymers suitable for the surface processing of synthetic paper to give an antistatic effect contain monomeric units derived from (I) a zwitterionic monomer of the formula (I) or (II): wherein R<SP>1</SP> represents H or methyl, R<SP>2</SP> represents a C 1 -C 6  alkylene group, R<SP>3</SP> and R<SP>1</SP> each represents and alkyl, alkenyl, acylaminoalkyl, hydroxyalkyl, alkoxyalkyl, polyoxyalkeylene or aryl group, M represents an alkali metal cation, the monovalent equivalent of a divalent metal cation, or a quaternary ammonium cation, and X represents a halide ion; and from (II) a hydrophobic monomer, the proportion of zwitterionic monomer units in the copolymer being from 5 to 95% by weight. The hydrophobic monomer can be any copolymerisable monomer which is not more than about 25% by weight soluble in water at room temperature; examples are styrene and substituted styrenes, esters of acrylic or methacrylic acid, (meth) acrylonitrile, chloroethylene, vinyl acetate esters of maleic acid, vinyl ethers, acrolein, allyl ethers, allyl chloride and butadiene. The copolymers may also include up to about 20% by weight of units of a hydrophilic monomer such as (meth) acrylic acid or a salt thereof, or (meth)acrylamide. Synthetic paper is produced by coating at least one surface of a paper-like synthetic resin film or sheet with a copolymer of the invention. The synthetic paper has improved antistatic, printability and other surface properties. Useful synthetic film includes laminated film as described in U.K. Specification 1268823, derived for example from polyethylene, polypropylene, ethylene/propylene copolymer and/or polystyrene. The copolymer can be applied to the film or sheet from solution or emulsion, or as a melt coating.

Abstract: 501,941. Windscreen-cleaners. OPEL AKT.-GES., A. Nov. 12, 1937, No. 31115. Convention date, Nov. 14, 1936. [Class 138 (i)] A windscreen-wiper mechanism of the kind which is driven from a rotating part of the engine through the intermediary of a clutch and is arranged to stop with the wiper in a predetermined position, is provided with a normallylocked control member adapted to be preset manually and then to be operated automatically to disengage the clutch and stop the wiper positively. The wiper, not shown, is oscillated by a crank 1 rotated by a worm-wheel 3 which meshes with a worm 5 on a shaft 4. The latter has a clutch element 4b co-operating with a clutch element 7a on a shaft 7 driven by a flexible shaft from the engine. The shaft 7 has grooves 10 meshing with teeth 11 on a member 12 mounted, with a lost motion connection, on a rock-shaft 13. With the wiper running, the member 12, is locked in the position shown by a catch 20. To stop the wiper, the shaft is turned counterclockwise by a manual control. A lug 22 on it then releases the catch 20, so that a spring 16 can rock the member 12, causing a member 27 to engage a sleeve portion 28 of the wheel 3. When rotation of the latter brings a slot 29 into line with the member 27, the member 12 is rocked further to disengage the clutch 4b, 7a, and the wheel 3 is arrested positively by the member 27. The wheel 3 is connected to the crank-shaft 1a by a pin 33, slot 34, and spring 30, so that it can slip in case of overload.

Abstract: 406,812. Regulating ; spray carburetters. MORRIS INDUSTRIES, Ltd-., Cowley, Oxford, and DAVEY, B. A., East Works, Bordesley Green Road, Adderley Park, Birmingham. Nov. 8, 1932, No. 31504. [Classes 7 (iii) and 7 (vi).] In means for automatically regulating the fuel supply in accordance with atmospheric or induction-pipe pressure by a bellows device, the bellows is connected with the control mechanism through resilient means which, in the event of failure of the bellows, allow the spring within the bellows to move the control mechanism independently of said resilient means, so as to maintain the fuel supply. The bellows may be replaced by a light piston or a flexible diaphragm. Fig. 1 shows a bellows a containing a spring band arranged in a casing c open to the atmosphere or connected to the induction pipe, so as to actuate a lever d which is connected to another lever e pivoted to the control member h, relay piston g, and valve f. The connection between the levers d and e is made of telescoping members i, j held together by a spring l; or the two levers may be connected merely by a spring. If the bellows should fail, the spring b moves the lever d into contact with a lever or spring blade o, which operates the valve f so as to cause movement of the piston g in the appropriate direction for maintaining the flow of fuel. In a modification, the bellows acts directly through a system of levers and links connected to the needle valve regulating the supply of fuel to the carburetter.

Title: A method of refining montan wax
IPC: C14C3/06
Filed: 1957-10-16
Abstract: Montan wax is refined by (i) treating with 40 to 50% by weight HNO3 at not more than 80 DEG C.; (ii) stopping the reaction after not more than 1 hour by adding cold water; (iii) washing with water and, without drying (iv) oxidising with chromic acid or sodium or potassium bichromate.  The final products are an almost white, hard wax of high acid number and a chromium mash useful for tanning leather (see Group VIII).  Heating is not required in step (i) which is exothermic, if the wax is previously crumbled. The temperature is kept below 80 DEG C. by choosing the concentration of the acid, within the limits 40 to 50%, according to the quantity and quality of the crude wax.  One part by weight of sodium bichromate is generally used per part by weight of wax.
