IPC: A45F3/44
Filed: 1951-09-04
Abstract: 697,767. Stands for picnic utensils. CAMPBELL, F. Sept. 3, 1952 [Sept. 4, 1951], No. 20814/51. Class 52(iii) A device for supporting vacuum flasks, cups &c, comprises a retaining ring formed from a wire loop the ends of which are bent at right angles to the plane of the ring to provide a leg or legs which can be forced into the ground. As shown, the ends of a wire loop a are bent to form legs B which are reinforced by transverse wires b<SP>2</SP> and a second ring b<SP>3</SP> preventing insertion too far into the ground. In a modification the legs depending from a corrugated wire ring are welded together and pass through a disc which supports the base of a cup or beaker too small in diameter to be held by the loop a. When used on an impenetrable surface three or more devices may be linked together by a clip or integral catch to form a stable unit.

Abstract: The invention comprises esters of the formula <FORM:0834575/IV (b)/1> wherein #f represents an ortho- or para-phenylene group or a group -Z-CR1R11- (Z being a C1-7 alkylene group and R1 and R11 representing hydrogen or C1-4 alkyl groups), n is 1 or 2, R represents hydrogen or an alkyl, alkenyl, benzyl or cyclohexyl group and R0 represents a monovalent or divalent residue of an ester-forming hydroxy compound when n is 1 or 2 respectively.  R0 may represent an alkyl, alkenyl, chloroalkyl, nitroalkyl, alkoxyalkyl, aryloxyalkyl, cycloalkyl, aralkyl, aryl, chloroaryl, nitroaryl, alkylene, polyglycol or polythioglycol residue.  The compounds are prepared by reacting, in the presence of a hydrogen halide acceptor, a compound of the formula CH2=CH-S-#f-NHR with a halocarbonate of the formula XCOOR0 or XCOO-R0-OOCX, where X is chlorine or bromine.  The compounds may be used to form homopolymers or copolymers. Compounds in which R is hydrogen yield the corresponding isocyanates when heated in presence of a base.  Compounds of the formula CH2=CH-S-#f-NHR are prepared by reacting aminomercaptans of the formula HS-#f-NHR, or an aminoalkylisothiuronium salt of the formula <FORM:0834575/IV (b)/2> (where Y is an anion), with acetylene under pressure in the presence of a basic catalyst.  Aminoalkylisothiuronium salts of the above general formula are obtained by heating compounds having the formula <FORM:0834575/IV (b)/3> with thiourea in an alcohol solvent.ALSO:Vinylthiocarbamates of the formula <FORM:0834575/IV (a)/1> wherein #f represents an ortho- or para-phenylene group or a group -Z-CR1R11- (Z being a C1-7 alkylene group and R1 and R11 representing hydrogen or C1-4 alkyl groups), n is 1 or 2, R represents hydrogen or an alkyl, alkenyl, benzyl or cyclohexyl group and R DEG  represents a monovalent or divalent residue of an esterforming hydroxy compound when n is 1 or 2 respectively, are homopolymerized or are copolymerized with vinyl or acrylic co-monomers, such as methyl methacrylate, in the presence of benzoyl peroxide or a azo-type free radical polymerization catalyst, such as dimethyl azoisobutyrate.  The polymers may be prepared in the form of gels or cast into sheets.  They serve as adhesives for glass, as modifiers for alkyd resins and as textile finishing agents.  The monomers of the above general formula may be used as plasticizers and stabilizers for polyvinyl chloride or vinyl chloride-vinyl acetate copolymers.

Abstract: 884,701. Lubricating. INSTITUT Dr. ING. REINHARD STRAUMANN A.G. June 21, 1960 [June 22, 19591, No. 21665/60. Class 12 (3). [Also in Group XVIII] A reservoir in a casing for a totally-enclosed mechanism facilitates the condensation of vapour lubricant contained therein. The material of the reservoir adsorbs or absorbs the lubricant or expands in the presence thereof so that the vapour pressure is thereby reduced. In an alternative way of reducing the vapour pressure in the reservoir, an expansible polymer for example, or an organic substance of a lower molecular weight, is added to the lubricant. In an embodiment, an annular reservoir 3 is located between a watch casing 1 and a movement 2, the components of which have not been lubricated. The back (not shown) is attached to the casing 1 and lubricant is deposited from the reservoir on to the movement 2.

Abstract: 1,209,281. Razor. BASSAT S.A. 29 April, 1969 [2 May, 1968], No. 21667/69. Heading B4B. A razor comprises a hollow handle 1, a blade rest 2 bearing a pivotable top cover 4, and locking means for retaining the rest 2 and cover 4 in engagement, the locking means including three tongue pieces 14, (15), 16, two of which 14, (15), are normally biased apart, Fig. 2 (not shown), but move together on downward movement of the locking means to engage a projection 6 of the top cover 4. On pressing the cover 4 into engagement, an inclined face 9 of the projection 6 pushes the upper end of the tongue piece 16 outwardly from engagement over the upper edge of a part 21 rigid with the handle 1, and a spring 11 draws the tongue pieces downwardly, causing the pieces 14, (15) to slide in resilient engagement against the edges of a wing 21a of the part 21. As curved upper ends of the tongue pieces 14, (15), Fig. 6, approach the wing 21a, the pieces move inwardly, engaged by tapering inner walls 26, 27 of the handle 1, their upper inwardly facing edges engaging over a bead 8 on the projection 6 to lock the cover 4. For disengagement, on pushing a button 12, the tongue pieces are raised against the action of the spring 11, the part 21 biasing the pieces 14, (15) apart as they slide upwards to release the bead 8, and the end of the tongue piece 16 resiliently re-engaging over the part 21.

Abstract: 1,161,354. Semi-conductor devices. RADIO CORPORATION OF AMERICA. 10 May, 1967 [8 Sept., 1966], No. 21699/67. Heading H1K. A semi-conductor layer having a plurality of adjacent regions in two groups of different conductivity type and/or resistivity is produced by separate growth of the groups of regions on a mono-crystalline substrate, for example of alumina or spinel. In an example, a sapphire (alumina) substrate is cut and lapped to a (1102) major face and is polished and is ultra. sonically degreased in chloroform. The substrate is placed in a deposition apparatus flushed with helium and hydrogen and is coated with silicon by thermal decomposition of hydrogen-diluted silane-the layer formed will be P-type since aluminium is vaporized from the substrate and also enters the layer by direct diffusion, but diborane may be added to the growth mixture to control the resistivity. After high temperature annealing, silica is grown on the layer in steam and the oxide coating photo-resist masked and etched (HF). The exposed silicon is etched to substrate level (KOHaq.) and, after removal of oxide and photo-resist, a second silicon layer grown, this time from silane doped with phosphine. The N-type layer formed is abrasively polished until the regions of the P-type layer are exposed to leave the structure of Fig. 1d. Complementary transistors (unipolar or bipolar) may be formed in such a structure for use in integrated circuits. The silicon layers may be shaped or reduced in general by etching, sawing, ultrasonic cutting, or polishing.

[Class 106 (ii)] A pneumatic micrometer is characterised by differential screw means for the initial regulation of the free section of the passage provided for the escape of the fluid serving for the measurement. A comparator has an arm 7 supporting a body member 10 in an adjustable manner, the body enclosing a sleeve 16 surrounding a gauging rod 11, a valve face on which co-operates with a valve seat 15 whereby pressure air, supplied through a pipe 6 to a chamber 18, escapes via passages 20, 21 to atmosphere, the valve opening being varied according to the height of a workpiece 9, the dimension of which is indicated by a pressure gauge taken off the pipe 6. To set the gauge, using a standard piece 9, the sleeve 16 is adjusted vertically by rotation of a member 26 through the differential action of a coarse thread 25 and a fine thread 24, until the pressure gauge indicates a standard pressure. The rod 11 may have an end cap 34. To facilitate the positioning of a work piece 9, the rod is raised against spring action by the depression of a lever 32. The lever 32 may be acted on by a plunger 36 controlled by a cam 39 and a handle 41, such that with the handle in one or other angular positions the lever 32 is in uppermost or lowermost position.
