Abstract: 405,954. Sliding seats. CHAPMAN, A. W., 115, Howards Lane, Putney, London. Aug. 13, 1932, No. 22761. Addition to 379,902. [Class 52 (ii).] In a modification of the sliding seat mechanism described in the parent Specification, a pair of co-operating slide members 1, 6, are constructed and interengaged so as to slide one upon the other with double line contact produced by the tangential engagement of the member 6 with two convex external surfaces 5, 5, formed by bending over both edges or sides 3 of the complementary member 1. The slide members are either held against transverse separation at all times, or are separable laterally when not in working position but provided with means for resisting such lateral separation, for example, by turning the sides of the member 6 downwardly and inwardly to form flanges 8, 8, and 9, 9, Figs. 1 and 3. A modification is shown in Fig. 5 in which the flanges 11, 12, 13 of the upper member 6 are turned first inwardly and then outwardly, and the sides of the lower member are turned inwardly.

Abstract: 1,241,161. Furnace seals. JOHNSON MATTHEY & CO. Ltd. 15 Aug., 1968 [17 May, 1967], No. 22949/67. Headings F4B and F4U. In a furnace for the continuous heat treatment of metal strip having inlet and outlet apertures for the continuous passage of said strip, the furnace is sealed against the escape of fluidized bed material from the furnace by incorporating magnetic particles within the fluidized material and subjecting at least the outlet aperture for the strip to the action of a magnetic field, thereby providing a curtain of magnetic particles for sealing the outlet. As shown in the Figure, adjacent the aperture is mounted an electromagnet 1 so arranged that the gap 2 between the poles encloses a tube 4 for the strip 3. The fluidized bed material may for example comprise zircon sand containing about 5% by weight of particles of Fe 3 O 4 , the said magnetic particles being attracted to and remaining in the tube 4 when the electromagnet 1 is active and held there by the magnetic field during operation of the furnace.

Abstract: 1,243,203. TiO 2  pigments. BRITISH TITAN Ltd. 16 April, 1969 [15 May, 1968], No. 22991/68. Heading C1N. Acid-reacting (i.e. having a pH <7.0 in aqueous suspension) TiO 2  pigment is neutralized (i.e. adjusted to pH 6À5-8À0) by heating at 150-350‹ C. in contact with a gas which is non-acidic and non-reactive to TiO 2 , mixing with aqueous alkali solution in an amount and for a time insufficient to slurry the TiO 2 , and further heating the TiO 2  in contact with the same or different non-acidic and non- TiO 2 -reactive gas at 150-350‹ C. Specified gases are steam, and air/steam or nitrogen/ steam mixtures. The amount of alkali used may be such that the treated TiO 2  contains less than 10% by wt. of H 2 O and the neutralized dry product contains 10-1000 p.p.m. of alkali. The alkali treatment may be effected by stirring the pigment with the alkali solution, or by spraying it on to the pigment. The TiO 2  may be treated, during the alkali treatment, gas heating or during a subsequent grinding step, with a coating agent such as a polyamine, an alkanolamine, or a polyol, e.g. pentaerythritol. In one example, Al 2 O 3 -coated TiO 2  from a gas-phase TiO 2  process is heated in steam before and after treatment with NaOH.

Abstract: 422,069. Lapping gears, screws, &c. BROWN & SONS (HUDDERSFIELD), Ltd., D., and MERRITT, H. E., Park Gear Works, Lockwood, Huddersfield. Aug. 18, 1933, No. 23048. [Class 60] In a machine for lapping gear teeth, screw or worm threads, &c., and in which the gear, &c., is rotated in contact with a lap having the form of a conjugate gear, &c., and is at the same time reciprocated, the workpiece c, shown as a worm, is mounted between centres d, e, on a table b, the centre d being directly driven by an electric motor f on the table. The motor also drives, through gearing g, h, h<1>, a shaft i carrying a disc il having in a slot i<2> therein, an adjustable crank-pin carrying a roller i<4>, which engages a slot j in a member j<1> adjustable on the machine bed a by a screw j<2> ; rotation of the motor thus drives the worm c and, through the crank mechanism, reciprocates the table b. The motor f is reversed after a predetermined number of reciprocations of the table by means of a switch t<2> operated by a pin t on the switch lever t<1>, the pin being engaged by a. collar s<4> on an axially movable sleeve s<2>, which carries pairs of differently spaced projections s, s<1> engaged by a projection r on a nut p<1> moved in a fixed guide p<3> by a screw p driven by gearing o, d from the shaft i. The sleeve s<2> is rotatable, to bring the required pair of projections s, s<1> into operative position, by a spindle s<3>, and at the end of the reversed stroke of the sleeve s<2>, the switch is opened and the motor f stopped. The worm c engages a lapping-wheel u carried on a spindle mounted in antifriction bearings in a head u<4> and geared to a rotary gear pump which serves to brake the movement of the wheel u, the pump having a relief valve v<1> whereby the braking torque may be adjusted as indicated by a pressure gauge v<2>. Abrading-compound is supplied to the work by a pump which is started and stopped automatically when the motor f is started and stopped. In operation, the work rotates and makes a predetermined number of reciprocations, as determined by the pair of stops s, s<1> in operation, the motor then being reversed whereby the work rotation is reversed, and, after the same number of reciprocations of the work the motor is stopped.

Abstract: 884,946. Fire extinguishing. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. June 23, 1960 [July 6, 1959; Dec. 21, 1959; March 17, 1960], Nos. 23105/59, 43330/59 and 9464/60. Class 47. A fire extinguishing powder, for use against burning uranium, plutonium or thorium metal, comprises a mixture of inorganic chloride and/or fluoride salts which are inert towards such burning metals and which are fused together and ground to powder in such proportions that the melting point of the mixture is below the melting point of the burning metal (e.g. 640C.). When extinguishing, a frit of halide forms excluding the atmosphere and cooling the metal by absorption of latent heat of fusion of the frit. In one example, the powder is a mixture of the chlorides of sodium (15-25%, or 35% or 20%), potassium (20-25% or 40% or 29%) and barium (50-55% or 25% or 51%); in another example, the powder comprises potassium and barium chlorides mixed with 20-40% of lithium fluoride. Caking may be reduced by the addition of 2¢% by wt. of magnesium stearate or prevented by storing the mixture in sealed containers. The extinguished metal may be separated from soluble chlorides by leaching with water.
