Title: Accelerators of vulcanization of rubber
IPC: C08K5/00
Filed: 1956-02-16
Abstract: The invention comprises esters of compounds of the formula HOOC-Ar-S-S-T, where Ar is an arylene group and T is a thiazolyl, thiazolinyl or arylenethiazolyl group attached in the 2-position. These are made by reacting a sodium or potassium salt of the 2-mercaptothiazole compound with an ester of a carboxyaryl sulphenyl chloride.  The latter is in turn obtained by the action of chlorine on an ester or a bis-(carboxyaryl)-disulphide.  The preparation of o-carbomethoxy-benzene sulphenyl chloride and 2-(o-carbomethoxyphenyl-dithio)-benzothiazole is exemplified.  the arylene group may be phenylene or naphthylene and may be substituted, e.g. by chlorine.  The esterifying group may be alkyl, aralkyl, cycloalkyl, aryl, including chloroethyl, cyanoethyl, butoxyethyl, chlorophenyl, nitrophenyl and methoxyphenyl.  The thiazolyl or thiazolinyl group may be substituted by alkyl or aryl.  The arylenethiazolyl group may be benzthiazolyl or naphthothiazolyl and may be substituted by alkyl, phenyl, nitro, chloro or ethoxy.  Many suitable groups are listed.ALSO:Rubber is vulcanized by heating it with sulphur and an ester of a compound of the formula HOOC-Ar-S-S-T where Ar is arylene and T is a thiazolyl, thiazolinyl or arylenethiazolyl radical attached at the 2-position.  Specified compounds are 2-(o-carbomethoxyphenyldithio)-benzthiazole, 2-(o-carbmethoxyphenyldithio)-benzthiazole, 2-(o-carbomethoxyphenyldithio)-thiazoline and many others in which the esterifying group is alkyl, chloroalkyl, cyanoalkyl, alkoxyalkyl, aryl, aralkyl or cycloalkyl, and Ar is phenylene or naphthylene optionally substituted by chlorine; T when thiazolyl or thiazolinyl may carry alkyl or aryl substituents, and when benzthiazolyl may be substituted in the benzene ring by alkyl, aryl, chlorine, nitro or alkoxy; T may also be naphthothiazolyl. The rubber may be natural or synthetic, the latter being polybutadiene, polyisoprene or a copolymer of butadiene, e.g. with acrylonitrile, isobutylene, styrene or vinylpyridine.  The vulcanising compositions may contain other materials such as pigments, plasticisers, extenders, oils or waxes. Specified compositions contain carbon black, stearic acid, zinc oxide, a softener and an antioxidant.

Abstract: 482,777. Vehicle lamps ; reflectors. AKTIEBOLAGET TIMBRO. Feb. 22, 1937, No. 5250. Convention date, Feb. 22, 1936. [Classes 75 (ii), 75 (iii), and 75 (iv)] In a vehicle lamp in which a main light source and reflector for long distance lighting, and an auxiliary light source and reflector for anti-dazzle close range lighting, are combined as a single unit, a vertical section through the axis of the auxiliary reflector is elliptical at the front, and at the rear is such that rays from a light source placed in or close to the posterior focus of the foremost elliptical part are substantially parallel after being reflected by said rear portion.. Fig. 1 shows an auxiliary reflector 1 having a paraboloidal rear part 1a with its focus at 2 and merging continuously into an ellipsoidal front part 1b with its foci at 3 and 4, rays from a horizontal transverse filament 5 passing through the focus 3 being formed into two beams 6, 7 and 8, 9 by the front and rear parts respectively. The axis of the paraboloidal part may coincide with or be slightly inclined downwardly with respect to the horizontal axis x-x of the ellipsoidal part. Alternatively, the elliptical vertical section of the front part may merge continuously or discontinuously into a parabolic horizontal section, Figs. 2a and 2b (not shown). Figs. 4a and 4b show a lamp casing 26 containing a main reflector 27 and its associated light source 28 and convex cover glass 29, and an auxiliary reflector 1 with its associated light source 30 and a spherical recuperating reflector 31, the auxiliary beam passing through a hole 32 cut in the main reflector 27. The cover glass may be in the form of a Fresnel lens, with vertical flutes to spread the light laterally, and with a plain toric portion for the passage of the auxiliary beam, Figs. 5a and 5b, (not shown). Fig. 6a shows the auxiliary reflector 1 lengthened in front so as to project some light downwardly and rearwardly through a window 36 to illuminate the front of the vehicle. The lower part of the paraboloidal rear portion of the reflector may be screened by a crescent-shaped shade 25. British Specifications 418,484, 437,001, and U.S.A. Specification 1,946,379 are referred to. The Specification as open to inspection under Sect. 91 comprises also (1) a convex cover glass of such curvature that substantially all the rays pass approximately at right-angles through it, and (2) a lamp in which the main reflector and its light source is dispensed with, (a) by continuing the auxiliary reflector below its axis and giving it a tilt to project through a slit-like opening in the lamp casing a combined long distance and close range beam of light, or (b) by mounting the lamp so that it may be dipped when required. In the form shown in Fig. 11b (Cancelled) the lamp 41 is mounted on a horizontal axlebearing 42 surrounded by a return spring 43 and operated by a lever 45 attached to a wire 44. The wires from a pair of such lamps pass over pulleys to a control device on the dash board. This subject-matter does not appear in the Specification as accepted.
