Title: Improvements in or relating to pigmented compositions
IPC: C09D7/47
Filed: 1953-03-12
Abstract: A pigmented composition comprises a paint or pigmented resinous coating composition and a resinous organosiloxane co-polymer composed of organosiloxane units and SiO2 units in such proportions that the ratio of organic radicals to Si atoms is from 1 : 1 to 2-5 : 1, the co-polymer having been made by the process of the parent Specification.  The coating compositions specified include mixtures of pigments, such as carbon black, titania, ferric oxide and hydroxide, lithopone, zinc oxide, zinc chromate, lead chromate, manganese silicate, various sulphates and arsenates, with oil-modified phenol-aldehyde resins, oil-modified resins alone or in combination with resins such as urea- and melamineformaldehyde resins, cellulose esters and ethers such as ethyl cellulose, cellulose acetate, and nitrocellulose, and acrylic acid ester resins. The copolymers are dissolved in solvents such as toluene, xylene, dibutyl ether and petroleum and added to the pigmented composition in amount, e.g. to give 0.001 to 0.01 per cent of the co-polymer based on the weight of the total composition.  In the example comparative tests are made by adding xylene solutions of (a) a co-polymer containing trimethylsiloxane and SiO2 units; and (b) dimethylpolysiloxane to a number of oil-modified alkyd resin type paints containing a variety of pigments.

Inventor: FRY DAVID PHILIP
IPC: C08L67/06
Filed: 1964-02-19
Abstract: A thermosetting moulding composition having as an essential component an unsaturated polyester contains in addition a saturated liquid polyester and sufficient thermoplastic polymer, which polymer is capable of being plasticized by said saturated liquid polyester, to prevent deleterious exudation of saturated polyester during the thermosetting of the moulding composition. The saturated liquid polyesters have melting points below 30 DEG  C. and are prepared by esterifying a polyhydric alcohol with a polybasic acid.  In the examples: (1) an unsaturated polyester formed from propylene and diethylene glycols, phthalic and maleic anhydrides and isophthalic acid and dissolved in styrene is mixed with benzoyl peroxide, lubricant, finely divided polyvinyl chloride, polypropylene adipate, carbonate filler and chopped glass fibres and the mixture is moulded; (2) this is similar to Example 1, but polypropylene sebacate is used in place of the adipate.  The other examples are similar except that the thermoplastic polymer is replaced by a butadiene-acrylonitrile copolymer or a vinyl chloride-vinyl acetate copolymer and the constituents of the unsaturated polyester are altered to propylene glycol, diethylene glycol, endo-methylene tetrahydrophthalic acid and maleic anhydride.

Abstract: 1,028,531. Drilling. BLACK & DECKER MANUFACTURING CO. Feb. 22, 1963 [July 30, 1962], No. 7183/63. Headings B3B and B3C. [Also in Division B4] A rotary-percussive drill comprises a ram 62 reciprocable in a barrel 16 by means of a crank 37 and a tool socket 100 having a gear 94 thereon driven by a pinion 76 which is loosely mounted on a shaft 71 and engageable therewith via a clutch 78, 79, 80. The crank 37 is rotated by an electric motor 11 via gears 36, 42 and connected with a piston 61 by means of a rod 60, cross-head 58 and connecting rod 55, the piston being reciprocated within the ram 63 so that air trapped within a chamber 64 causes the ram to rapidly strike the end 104 of a tool bit 101; the motor also drives the shaft 71, via gears 43, 53, 52, 72. The socket 100 is of hexagonal shape and formed in a sleeve 97 connected to the gear 94. A further hexagonal socket 110 is formed in a nose piece 19. In operation, if it is desired to rotate and hammer the tool bit, the latter is formed with a shape as shown in Fig. 13, in which the hexagonal end 104 of the bit extends into the cylinder 59 for the ram 62 so that the end is struck while it is rotated by the sleeve 97 and gears 80, 94. When rotary drilling only is required, a tool bit having an hexagonal end 104 which does not project beyond the sleeve is provided so that the end cannot be struck by the ram; during this type of drilling the ram is held at the forward end of the cylinder by a split collet 88, Fig. 17 (not shown). When hammering only is required a tool bit is fitted which instead of the end 97 being hexagonal so that it is rotated, the end is made circular thereby allowing the sleeve to rotate without turning the bit; in order to prevent any possible rotation due to friction, a portion of the bit is formed with a hexagonal shape so as to fit the socket 110, Fig. 15 (not shown). The clutch may be adjusted so that it will slip if the tool is overloaded.
