Title: Organic mercury compounds and their manufacture
IPC: C07F3/12
Filed: 1935-11-22
Abstract: Oil solutions of arylmercury compounds are prepared by heating an arylmercury acetate with one equivalent of a fatty acid derived from a fat or fatty oil in the presence of a hydrocarbon oil having a boiling point above 120 DEG  C.  The arylmercury acetates, e.g. phenyl-, tolyl-, xylyl- and naphthyl-mercury acetates, are obtained by treating the corresponding hydrocarbon in acetic acid solution with mercuric acetate at a temperature of about 110 DEG  C. Fatty acids mentioned are oleic, stearic, palmitic, erucic, linoleic, ricinoleic, oleomargaric, oleostearic, lauric, and sebacic acids. Examples are given of the preparation of solutions of phenylmercury oleate and tolyl-mercury oleate in paraffin oil by heating a suspension of the corresponding mercury acetate in the oil with oleic acid until all the liberated acetic acid has distilled away.  The Specification as open to inspection under Sect. 91 also describes the use of aryl-mercury acetates which are substituted in the nucleus, e.g. p-chlorophenylmercury acetate, phenetylmercury acetate, and b -naphthol-1 and 5-mercury acetates; and contains examples of the preparation of oil solutions of p-chlorophenylmercury oleate and b -naphthol-1-mercury oleate by heating the corresponding acetates with oleic acid in paraffin oil.

Title: Golf balls
IPC: C08K5/09
Filed: 1976-08-05
Abstract: 1524422 Moulding isometric golf balls PRINCETON CHEMICAL RESEARCH INC 5 Aug 1976 [7 Aug 1975] 32664/76 Heading A6D [Also in Division B5] A method for forming an isometric golf ball comprises extruding or sheeting an elastomer, forming a slug from the extrudate or sheeted material, disorienting the lines of orientation formed during extrusion or sheeting and moulding the slug in a mould. The disorientation may take place during the formation of the slug or whilst the slug is being inserted in a mould. The disorientation may be achieved by cutting the extrudate or sheeted material into portions and assembling the portions into a slug with the lines of orientation in different directions, by rolling the sheeted material into a cylinder so that the lines of orientation extend circumferentially and cutting a slug therefrom or by forming a slug having a shape which causes buckling of the shape when the slug is inserted into a mould. Examples of the latter are slugs formed by extruding through dies of Maltese cross, three or four leaf clover, oval, circular or semi-circular shape. The elastomer e.g. polybutadiene is cross-linked by an agent comprising one or more metal salts of one or more unsaturated polymerisable organic acids or imides, the salt or at least one of the salts being homopolymerisable. The agent may be preformed, may be formed insitu during compounding of the elastomer, may be partially prepolymerized and may be copolymerized with one or more metal-free monomers. Many examples are given, the zinc, magnesium and calcium salts of methacrylic, acrylic, cinnamic, aconitic, crotonic, itaconic, vinylacetic, styrenesulphonic or benzoylacrylic acid. Fillers such as zinc oxide, silica and impact modifiers e.g. polythene and ABS may be employed. The golf ball may be provided with an ionomeric coating.

Abstract: 366,153. Soldering. KEEL, C., 22, Kandererstrasse, Basle, Switzerland. Nov. 4, 1930, No. 33166. [Class 83 (iv).] In an apparatus for automatically soldering longitudinal or annular joints, of the type in which relative movement is effected between the work and the burner and solder wire, the burner and solder wire holder are so arranged on a fixed and non-portable supporting frame that they move relatively to the work with the burner preceding the solder wire in the direction of motion. The burner a, which may be arranged at an acute angle to the direction of motion, may be adjustably secured to a holder b traversed by a screw d, which is rotated by a motor k, when soldering longitudinal joints as shown. The screw co-operates with a part nut e, which may be disengaged from the screw through a slot e<1> and eccentric pin f operated by a handle f<2>, when soldering annular joints. In the latter event one of the rollers n which support the work is driven by the motor through a clutch s and chain m so as to rotate the work. The holder has a bracket b<5> with a pair of arms b<4> loosely mounted on the screw between which is mounted a disc feathered to the screw and carrying peripheral and also lateral cam teeth for oscillating the guide c for the solder wire 'o across the joint. When soldering longitudinal joints, the pivot c<2> of the sleeve c<1> which surrounds the guide c is adjustably secured in a slot in the part b<3> of an angle-piece secured to the holder, while for annular joints it is secured in a slot b<2> in the other part thereof. The guide is connected to the angle-piece by a spring. The solder wire is arranged at an obtuse angle with respect to the direction of motion and moves along the joint in rear of the burner. A single wire or a series of wires, Fig. 9, may be utilized and they may be fed down positively or by gravity. The joint is supported by a channel member C which radiates heat back to the work. An auxiliary burner may be used to melt the solder. The burner a. Fig. 10, may be secured in a clamp K pivoted on the end of a rod K<1> projecting from a lever H having a rod T to support the burner. The lever is pivoted at K<2> to a vertically adjustable block J. The lever is adjustable by a spring and screw E passing through a bracket G secured to the piece G supporting the solder guide c. The slide J is mounted in the cheeks Ll of a slide L which is adjustable transversely in a slide N<1>. The slide N<1> is adjustable by a screw S on a wheeled carriage N driven by a motor, spring mechanism or a weight. As shown, a motor Q drives through adjustable belt gear Z. The adjustment of the screw S constitutes a fine adjustment for equalizing a too quick or too slow advance of the carriage. The solder guide and frame P may be hollow and water cooled.
