Title: Improvements in or relating to co-polymeric organosilicon resins
IPC: C08G77/50
Filed: 1951-03-13
Abstract: A resinous organosilicon copolymer, containing the units RSiO1,5 and <FORM:0692829/IV (a)/1> , in which the ratio of R + R1 to Si - O bonded Si is from 1 to 1.6 inclusive and in which the units are connected by Si-O-Si bonding, is made by cohydrolysing and co-condensing a mixture of RSiCl3 and one or more silanes of the general formula R1nSiCl-n, wherein R is a (CH3)3Si.CH2-group or a (CH3)2.C6H5.SiCH2-group, R1 is an alkyl or monocyclic aryl radical and n has an average value of from 1 to 2 inclusive.  The hydrolysis with water, which may contain isopropyl alcohol, and condensation may be effected in the presence of solvents such as toluene, and at temperatures from 0 DEG  to 250 DEG  C.  The products are used for making heat and weather resistant coatings for boilers, stacks, ovens and other hot metal surfaces.  In examples, copolymers are made from mixtures of: (1) CH3SiCl3, (CH3)3SiCH2.SiCl3 and C6H5.CH3SiCl2; (2) (CH3)3SiCH2.SiCl3 and CH3SiCl; and (3) C6H5(CH3)2.SiCH2SiCl3, C6H5.SiCl3 and CH3SiCl3.ALSO:The silane (CH3)3SiCH2.SiCl3 may be mad by reacting silicon tetrachloride with (CH3)3Si CH2MgCl or (CH3)3SiCH2Li.  The silane (CH3)2.C6H5SiCH2SiCl3 may be made in a similar manner.  According to the examples, the reactions are effected in the presence of solvents such as ether, pentane and toluene.  The organolithium reactant may be made by gradually adding (CH3)3SiCH2Cl to a finely-divided suspension of lithium in mineral oil, and the Grignard reagent may be made by reacting magnesium with (CH3)3SiCH2Cl.

Patent GB-417912-A (GB)
Title: Improvements in and relating to rubber derivatives
IPC: C08C19/04
Filed: 1933-04-11
Abstract: Rubber derivatives, especially resins, are prepared by oxidizing rubber in solution in the presence of a metallic oxidizing catalyst soluble in the rubber solvent or capable of being dispersed therein and evaporating the solvent.  Suitable solvents are benzene, carbontetrachloride, chloroform or white spirit, and the oxidation may be accomplished by means of air, oxygen or ozonized air preferably at temperatures between 50 and 90 DEG  C.  Suitable catalysts are the oleates, resinates, tungates and linoleates of copper, lead, manganese and cobalt.  Some of these compounds, the tungates and linoleates, are precipitated by the oxidizing treatment, and may be separated from the solution of resin by centrifuging filtration or decantation.  In an example, a solution of 20 parts by weight of milled rubber in 100 parts by volume of white spirit is taken and to it is added 15 parts by weight of cobalt linoleate.  The solution is heated to 80-90 DEG  C. and air is bubbled through until a flocculent precipitate forms (5,7 hours): the precipitate, probably an oxidation product of the cobalt linoleate, is removed and the solution is evaporated to obtain the resin.  Other examples are given.  The resins obtained may be viscous liquids or plastic solids, and may be used for many purposes for which natural and artificial resins are used, e.g. for coating, impregnating, insulating, as adhesives &c.  The resins are thermoplastic and may be hardened by heating above 70 DEG  C.  Certain vulcanizing accelerators, e.g. tetramethylthiuram disulphide or zinc isopropylxanthate facilitate the hardening. Fillers may be added, and the resins may be vulcanized, with or without other substances.  The Provisional Specification also states that the oxidation can be carried out without a catalyst, and also that the invention could be carried out with latex which may be emulsified with oil, e.g. linseed oil prior to the addition of the catalyst, or the catalyst might be dispensed with and an oxygen carrier, such as an acid, employed.

Abstract: 1,101,091. Valves. HONEYWELL Inc. 17 Feb., 1965 [24 Feb., 1964], No. 6842/65. Heading F2V. Flow of gas to pilot and main burners is controlled by a tapered valve plug 17, Fig. 2, loaded by a spring 23 and having a sleeve extension 17a to which is splined the actuating knob 39. A safety valve 24 which seats on the smaller end of the plug 17 and controls the gas supply thereto is joined by a lever 25 to the armature 29 of an electromagnet 27 connected to a thermocouple energized by the pilot burner, the lever being biased by a spring 30 to seat the valve 24; the latter incorporates a bore for a reset stem 33 passing through the plug 17 and attached to the knob 39. The stem 33 is associated with two springs 35, 38, the former being weaker than spring 30. The knob 39 embodies an arcuate shoulder 39a that coacts with an abutment 42, Fig. 4, to prevent axial motion of the knob relative to the plug when the latter is in the " ON " position, in which position the main burner is supplied with gas via a pressure regulator; in the " PILOT " position the shoulder 39a permits sufficient axial movement of the knob to open valve 24, Fig. 2, and reset the armature 29 within the electromagnet 27. A member 43, attached to the knob by peripheral recesses 43a, 43b, Fig. 3, is formed with two arcuate abutments 46, 47 that co-operate with part 42b, Fig. 4, of the abutment 42 in the " OFF " and " PILOT " positions of the plug, respectively. The member 43 serves the dual purpose of providing an indexing means for the plug, and retaining means for the actuating and re-setting means for the plug and safety valve as well as preventing undesirable removal of the plug. The knob 39, Fig. 2, must be depressed before it is possible to rotate the plug to and from the " OFF " position whilst the plug can be freely rotated between the " PILOT " and " ON " positions. If the plug 17 is provided with an additional position wherein it is necessary to rotate the abutment 47 over abutment 42, the knob must again be depressed. A further abutment 22a may be provided to contact opposite sides of the abutment 42 and limit the rotation of the plug.

Cauldrons; surface treatment with liquid materials.-Relates to machines for spraying tar and like viscous material on roads of the kind in which a tar pump B disposed within the tar tank A sucks the hottest tar through a pipe G provided with a float g. According to the invention, the pump connections are so arranged that the tar drawn from the tank may either be delivered through a pipe E to the spraying nozzles F or circulated back to the tank through a pipe H, or the pump may suck hot air through a pipe J from the upper part of the tank and deliver it through the spray pipes and nozzles to scavenge them. The delivery pipe E and transverse spray pipe E<2> are surrounded by jackets e fed with steam or hot gases. Flexible tubes N fitted with nozzles n for spraying paths are connected to each end of the spray pipe E<2>. The tar boiler has a furnace C the flues c of which extend under and through the tank to give a large heating surface. The tar boiler is mounted on girders X for ready attachment to a motor vehicle, and the top of the tank is fitted with a crank shaft b whereby the pump is driven by chain gearing from any suitable source of power or from the road wheels. The tar barrels are supported over the feed openings D bv rollers d. According to the Provisional Specification, grids heated by the flue gases are arranged on the upper part of the tank to support and preheat the thick tar until it is sufficiently fluid to pass through the grids. The top of the tar tank is also in the form of a tray to prevent tar which boils over reaching the furnace.
