Abstract: 814,855. Heat exchangers. AIR PREHEATER CORPORATION. May 30, 1957 [Aug. 31, 1956], No. 17155/57. Class 64(1) In a heat exchanger unit comprising an upright housing 10 in which a fluid stream is heated by or gives up heat to a stream of pellets 16 flowing through the housing in the opposite direction to that of the fluid, a plurality of superimposed layers of horizontally spaced distributers extend across the housing in a direction generally normal to the direction of flow of the pellets. The distributers, which may comprise either a plurality of rods 36 (as shown) or rows of planar members alternately inclined to provide a zig-zag flow path, are preferably arranged between the fluid inlet 26 and outlet 28 of the housing 10. Above, and if desired, below the distributers 36, means are provided to restrain the flow of pellets adjacent the pellet inlet and outlet to and from the housing in order to prevent fluid leakage, and may comprise either a perforated plate or (as shown) rods 42A, 42B of smaller diameter and more closely spaced than are the rods 36. In the form shown, two units are superimposed. Downwardly moving pellets receive heat from hot gas flowing through the upper unit and give up this heat to air flowing through the lower unit, the pellets being recycled to the upper unit by a conveyer 22. The cross-section of the distributing and retaining rods 36, 42A and 42B may be circular, or streamlined with a flat upper surface.

Title: Improvements in shed forming mechanism for jacquard looms
IPC: D03C3/06
Filed: 1923-07-03
Abstract: 221,306. Hollingworth, E., (Crompton & Knowles Loom Works). July 3, 1923. Jacquards.-The comber board 36 or a holder therefor is pivoted at 37 to a lower lifter frame 34, which is vertically reciprocated by yokes &c. 33 and levers 23 linked to levers 22 operated by lever mechanism from cams. When the frame 34 is raised, adjustable stop-screws 38 on the comber board &c. engage a side bar 39 on the frame whereby the comber board is held at anv required angle. When the frame 34 is lowered, projections 40 on the comber board holder engage adjustable stop screws 41 on a fixed stand and determine the inclination of the holder, lost motion of one edge portion of the comber board relatively to the lifter frame occurring. The piLe warps can thus be disposed in a uniform horizontal or inclined position when raised or lowered. The levers 22 are connected by adjustable links 26 to an upper lifter frame 27 having bars 28 to raise jacquard wires to form the pattern. The frame 27 is given a tilting move. ment by means of cam slots 31 and studs 30 as it rises, so that the wires remote from the reed may be raised higher than the others to bring all the raised pile warps into the same stud. The lower lifting frame has a vertical movement of less extent than the upper lifting frame, the extent of movement of the left end of each lever 23 being about half that of the left ends of the levers 22.

Abstract: 693,267. Electric systems for indicating and transmission of correspondence control. STEIRISCHE GUSSTAHLWERKE AKT.-GES July 23, 1951 [Aug. 12, 1950]. No. 17378/51. Class 40 (i). [Also in Group XXII] In a continuous casting- machine the level of the molten metal in the mould is determined by using the contents of the mould to influence the inductivity of a coil traversed by an electric current and arranged adjacent said surface but outside the mould. A coil 10 may be arranged about a copper mould 1 cooled by a non-magnetic water jacket 2. Steel may be poured at 5 and the solid bar 8 is withdrawn by rollers 9. When the level 7 falls, the alternating current in the coil 10 increases and may show on an indicator, be used to increase the flow of molten steel or reduce the feed by the rollers 9. The mould etc. are made of non- magnetic material to avoid blotting out the small changes in inductivity due to changes in level of the molten metal. The coil 10 may be arranged in one arm of a bridge circuit and the resistances in the other arms are adjusted to give no current through the meter for a definite level of the molten metal. When the level alters current flows through the meter and this may be amplified for operating the control means. When non-magnetic metal is cast, changes in eddy-current losses alter the inductivity of the coil.

Title: Alumina
IPC: B01J21/04
Filed: 1942-12-10
Abstract: 568,978. Alumina ; catalysts. HOUDRY PROCESS CORPORATION. Dec. 10, 1942, No. 17603. Convention date, July 5, 1941. [Classes 1 (i) and 1 (iii)] Alumina of high stability and resistance to disintegration which may be used as a catalyst or catalyst carrier, is obtained by subjecting precipitated hydrous alumina to " hot ageing " for 10 mins. to 2 hrs. at a temperature between 125‹ F. and 212‹ F. (or higher under pressure), washing substantially free of soluble salts, grinding until at least 70 per cent will pass through a 400-mesh screen, forming the ground alumina into pieces and heat-treating at 1000- 1600‹ F. The product in the form of pellets 4 mm. in diameter has a " knife-edge hardness " of at least 3500 grms., and its content of alkali is below 0.5 per cent Na2O. In examples : (1) alumina is precipitated from a sodium aluminate solution by ammonium chloride and " aged " with or without prior separation of the mother liquor, the aged precipitate being filtered and dried before washing, and again filtered and dried before grinding. After grinding, the alumina is wetted to produce a dough which is pelleted, and the pellets dried at room temperature or baked at 275‹ F. prior to the final heat treatment. Wetting may be effected with water or aqueous alcohol, acetone or kerosene ; (2) alumina is precipitated from an aluminium nitrate solution by ammonium hydroxide either at temperatures within the range for " hot ageing " or at room temperature with subsequent heating of the reaction mixture, the precipitate being further treated as above described. Composite catalysts may be obtained by dipping the product in solutions containing the desired additional catalyst, and drying and heating to decompose the solution. For example, a product containing 11 per cent of molybdenum trioxide may be obtained, using a solution of ammonium paramolybdate, and one containing 1.7 per cent of vanadium pentoxide from a solution of ammonium metavanadate. The use of solutions comprising compounds of tungsten platinum, silver and iron is also referred to, and incorporation of metals or compounds of chromium, cobalt, nickel, uranium and zirconium. The products of the invention may be used in processes for the hydrogenation, dehydrogenation and cracking of hydrocarbons.

Title: Improvements in ordnance sighting apparatus
IPC: F41G1/393
Filed: 1920-07-02
Abstract: 145,733. Krupp Akt.-Ges., F. Jan. 18, 1918. [Convention date]. Sights.-Consists (1) in causing two members of a gun elevating or training gear which turn on parallel axes, respectively to drive the two rotary co-axial members of an indicator by gearing which has in each case the same ratio of transmission, and which rotates the indicator members at a rate faster than that of the corresponding members of the elevating or training gear, and (2) in adapting the indicator members to rotate through more than 360 degrees and in providing fiducial marks, one on each member, whose radial distance apart varies with their angular separation. In the form shown, as applied to elevating-gear, a sector B<3> is fixed to the trunnions b<1> of the gun cradle B, and meshes with a pinion M riding loosely on a shaft K mounted in the gun carriage C. Rigidly connected to the pinion M is one disk M<1> of the indicator, having a spiral slot m<2> cut in it, and carrying an index mark m<3>. The sighting telescope G<2> is mounted on a sleeve G rotatable for pointing on a bearing sleeve c<1>, fixed to the gun carriage, by worm-gearing H. Turning in the sleeve c<1> is a shaft F<1> carrying a scaled sector F<3> rotatable, to set it to the angle of tangent elevation with respect to a fixed mark on the casing G, by worm-gearing J. With the shaft F' rotates a lever F connected by a parallel motion linkage E to a lever D, which turns loosely on the trunnion b<1> and is fixed to a sector D<1> meshing with a pinion k<1> fixed on the shaft K. Rigidly connected to the shaft K is the other disk K<2> of the indicator, and radially mounted on this disk is a slide K<3> which carries an index mark k<4> and a pin k<5> engaging the spiral groove m<2> in the disk M<1>. The gear ratio B<3>/M is equal to the ratio D<1>/k<1>. The index marks k<4>, m<3> are so arranged that they coincide when the axes of the gun A and the telescope G<2> are parallel and the scale F<3> indicates zero tangent elevation. In use, the telescope G<2> is layed on the target by actuating the gear H. The tangent elevation is set on the scale F<3> by actuating the gear J, and, through the gearing F<1>, F, E, D, D<1>, k<1>, K rotates the disk K<2> thereby angularly displacing the slide K<3> from the mark m<3> and, by reason of the pin k<5> working in the slot m<2>, radially displacing the slide K<3> and its index mark k<4>. The, tangent elevation is now imparted to the gun by operating the elevating-gear B<2>, which rotates the disk M' through the gearing b<1>, B<3>, M, and simultaneously displaces the slide K<3> radially owing to the gear m<2>, k<5>, until the coincidence of the index marks m<3> and k<4> is restored both angularly and radially.
