Abstract: 441,130. Gyroscopic apparatus. MOSS, D. G. K., 45, Arundel Avenue, Sanderstead, and PIERCE, H. C., (trading as MECHANISM), 6A, George Street, Croydon, both in Surrey. June 14, 1934, No. 17682. [Class 97 (iii)] An erecting device for gyroscopic verticals or artificial horizons comprises oppositely directed air jet orifices controlled by a body which rolls when the gyro deviates. In the form shown, the gyro casing b pivots on a transverse axis in a U-shaped frame d which is rotatably mounted by means of a hollow spindle d<1> and spaced bearings e on a fore-and-aft axis in the outer casing f. The gyro casing b carries a pair of valve chambers g<3> with their axes at right angles to each other and each having oppositely directed air jet orifices g<4>. Air is exhausted from the casing f through the opening h and is drawn in through the hollow spindle d<1>, hollow frame d, and hollow transverse pivots to drive the rotor a and then passes out of the valve chambers as normally equal and opposite air jets. A disc valve g, covering the oppositely directed orifices to an equal extent when the gyro is vertical, has central pins g<1> rolling in arcuate slots g<2> so that when the gyro tilts the disc moves to cover the orifices pointing in one direction and uncover those pointing in the opposite direction, thus giving rise to a torque tending to restore the gyro to the vertical. In a modification the oppositely directed orifices are controlled by a plunger valve actuated by rolling balls on either side. In a further modification Fig. 7 the passage of air to the oppositely directed orifices m<4>, m<5> is controlled by a single ball m. The fore-and-aft inclination of the supporting craft is indicated by an arm n fixed to the casing b and moving in a slot in a dial o<1> carried by the U-shaped frame d. The transverse inclination is indicated by the rotation of a ring p, fixed to the casing f, relative to the dial o<1>.

In a modification the hand-grip extends at an obtuse angle to the stem 2, the lever being formed of a double length of stiff wire, the ends being splayed in for pivotal connection with the hand-grip and the lever being bent to provide a finger grip portion lying near to but spaced from the hand grip. In another modification, for picking up hot objects, an asbestos strip is stuck to the inner face of each of the finger portions of the spring tongues.

Abstract: 644,726. Cutting stone. LEMOINE, G. July 7, 1948, No. 18214. Convention date, July 8, 1947. [Class 124] A saw for cutting stone or like hard material has a longitudinal core of unvarying non-circular cross-section, twisted helically with reference to its axis, which carries with a snug fit a plurality of similar cutting tools, the angular setting of which varies with the twist of the core. As shown, a triangular core 1 is twisted helically along its length and has fitted on it a plurality of triangular cutters 2 which may be separated from each other by flexible distance pieces, e.g. springs 5. The angular disposition of the apices 3 of the cutters depends on the twist of the core. Other shapes of core, square or rectangular, Figs. 5 and 6 (not shown), or a three strand cable, Fig. 3 (not shown), are illustrated as well as other shapes of cutters. Owing to the twist in the core and the presence of flexible distance pieces any longitudinal movement of the cutters results also in a rotary movement of the cutters. The cutters may have cutting edges of hard material, e.g. tungsten carbide, or may have annular plates of hard material fixed to softer metal bases, the aperture in the plate being larger than that in the base.

A wheeled carriage 15 having a hydraulic lifting jack 7 and means 9 for rotation of the jack may be placed beneath the vessel, the wedges between the lower claws and the trunnion ring removed, and the vessel raised clear of the trunnion ring; the vessel may then be rotated through any desired angle e.g. 90 degrees and replaced on the trunnion ring. A cover 10 may be provided for the vessel, which cover is raised before rotating the vessel so that no rotary movement of the cover takes place.

Abstract: 561,290. Building up articles by spraying. EDWARDS, H. F. Dec. 29, 1942, No. 18439. [Class 83 (iv)] In making articles by spraying metal on to a former and then stripping the article therefrom, a magnetic metal, e.g. steel or alloy steel, is used and, during at least the initial stages of the spraying operation, arranging a magnetic field to act in direction to retain the sprayed particles in contact with the surface of the former. This may be done by arranging an electromagnet 14 below the former 11 which is made of a non-magnetic material such as synthetic resin, laminated paper or wood pulp treated with synthetic resin, or low-melting-point alloys, e.g. lead bismuth alloy.. Where a non- uniform layer of sprayed metal is required a non-uniform field may be used, e.g. by making the former of magnetic material. The electromagnetic field is preferably cut off when all the surface 12 has a coating of sprayed metal..

Materials for purifying.- A small percentage, e.g., 0.7-0.2, of a wetting agent such as is used in the textile industry is added to the washing liquid in order to retain dust. The wetting agent consists of an aromatic, hydro-aromatic or higher aliphatic sulphonic acid or salt, or a mixture of two or more of such acids or salts, if necessary with addition of an organic solvent. In an example 1-2 grams of sodium benzylnaphthalene-sulphonate per litre of washing water are employed in washing blast-furnace &c. gases. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the addition of an organic solvent adapted to prevent the formation of froth, e.g. tetrachlorethylene. The proportion of solvent varies preferably between 5 and 100 per cent of the wetting agent. In an example air withdrawn from a briquetting works and containing a large quantity of coal dust is blown through a Raschig tower to which cold water is supplied containing per litre 2.5 gr. of sodium isopropylnaphthalene-sulphonate and 0.5-2.5 gr. of perchlorethylene.

A method of sizing a split ring of sheet metal comprises the step of forcing the ring through a sizing die by means of a punch which restricts the axial flow of the ring material. A sizing punch 1 is driven through the ring, which may be a bearing liner, progressively expanding it until it slips into a portion 3 of reduced diameter. A chamfered face 5 of the punch forces spring-loaded stop dogs 9 apart and drives the liner 4 into the sizing portion 2 of the die. The surface 8 forms the liner, which is axially confined by shoulders 3a, 3b. On the return stroke of the punch 1, the protruding top edge of the liner 4 engages a stripping ring 6a and a chamfer on the shoulder 3a resiliently expands the liner so that the punch may be withdrawn therefrom. In an alternative embodiment the punch has a guide member (10), Figs. 3, 4 (not shown), formed below the face 5 and which co-operates with a guide bore (11). Stops may be provided below the surface 8 to strip the sized liner 4 from the punch 1 and allow it to fall from the sizing die.
