Title: Improvements in or relating to the packing of products in containers
Inventor: COOPER GRAHAM BAPTIE
IPC: B21D51/32
Filed: 1964-06-03
Abstract: 1,043,095. Packaging; coatings for containers. CATALYTIC GAS PACK Ltd. April 21, 1965 [June 3, 1964], No. 23056/64. Headings B8C and B8D. [Also in Division A2] The residual oxygen contained in the air space 8 above the contents 9 of a can is combined with hydrogen, introduced into the container before the end closure 1 is applied by means of a catalyst dispersed in a liquid vehicle with a support material and a binder and coated on the surface of a part 11 of a sealing compound 6. The catalyst may be applied to the whole of the compound 6; or an uncoated portion of the compound 6 may stop short before the wall 2 of the lid, and a coated portion of the compound, spaced from the uncoated portion, may be applied to the flange 4 and to the wall 2. Again, the compound 6 may be omitted, and replaced by a catalytic compound which also forms a seal. The support material may be carbon, alumina, silica or calcium carbonate. The catalyst may be palladium, platinum, rhodium, iridium, ruthenium or osmium. The binder may be gum tragacanth, gelatin, dextrin, gum arabic, albumin, casein, or polyvinyl acetate. The catalyst may be applied to both ends of the container, or to one end only. Where it is applied to one end only, it may be either applied to the closure or to the base of the container. Where it is applied to the base, the filling of the container takes place subsequently. In a modification, Fig. 5 (not shown), the wall 2 is formed with an inward shoulder which enables a larger area of the coated seaming compound to be exposed to the container interior. The material in the container may be beer, dried milk or a product other than food.

Title: Improvements in the manufacture of intermediates and a dyestuff of the anthraquinone series
IPC: C07C225/34
Filed: 1920-08-05
Abstract: 3-Chlor-2-aminoanthraquinone is obtained by limited chlorination of 2-aminoanthraquinone suspended in a liquid such as glacial acetic acid.  Bromination of the chlorobody yields 1-brom-3-chlor-2-aminoanthraquinone which by heating in the presence of copper salts is converted into a blue vat-dyestuff, probably 3 : 31 - dichloranthraquinone - 1 : 2 : 21 : 11 - N : N1 - dihydroazine. The operations of halogenation and condensation may be carried out successively in a common liquid.  According to examples:-2-aminoanthraquinone is chlorinated in glacial acetic acid or nitrobenzene, in the latter case, if desired, with addition of sodium carbonate; 3-chlor-2-aminoanthraquinone is brominated in nitrobenzene in presence of sodium carbonate; 1-brom-3-chlor-2-aminoanthraquinone is condensed to dyestuff by heating in nitrobenzene with sodium and copper acetates; the operations of chlorination, bromination, and dyestuff formation are consecutively carried out in nitrobenzene suspension.  Specifications 7692/04 and 18196/05 are referred to.

Title: Liquid-level-responsive device
Inventor: JOFEH MARCUS LIONEL
IPC: G01F23/44
Filed: 1958-07-18
Abstract: 882,087. Electric indicating systems. SPERRY GYROSCOPE CO. Ltd. July 23, 1959 [July 18, 1958 (5)], Nos. 23210/58, 23211/58, 23212/58, 23213/58 and 23214/58. Class 40 (1). Apparatus for indicating the level of liquid in a container comprises a float automatically maintained at a constant degree of immersion in the liquid by keeping its apparent weight constant. As shown, a float 7, partly submerged in a liquid 1, is supported from one end of a weighing team 3 by a cable 14. The weight of the cable drum 5, a motor 8 and the apparent weight of the float are together balanced by a counterweight 16. Changes in the liquid level vary the depth of submersion of the float and hence its apparent weight, whereupon the beam 3 tilts by an amount measured by inductive pick-off 17, the tilt signal being fed to motor 8 which drives the cable drum 5 to adjust the length of cable 14 until the beam is rebalanced, the rotations of motor 8 being indicated by a pointer 18. The float 7 is supported vertically under the axle 15 of the cable drum 5, in a double sleeve arrangement 21, 23 with adjustable holes 22 to prevent the apparatus from responding to rapid changes in liquid level. The beam 3 and associated apparatus is enclosed in a casing 26 filled with air or an inert gas under pressure to prevent corrosive or explosive gases from the liquid from entering, and may be supported on a wall 2 of the liquid container.

Title: Engine starter
IPC: F02N15/02
Filed: 1948-09-08
Abstract: 651,363. Turning-gear. BENDIX AVIATION CORPORATION. Sept. 8, 1948, No. 23644. Convention date, Sept. 18, 1947. [Class 7(v)] In an engine starter comprising a rotatable engine engaging member 14 having means, such as a helically wound strip 32 of phosphor bronze or similar material, for restraining the member 14 against rotation to effect axial movement thereof into engagement with the engine, and driving means, for example the motor 50, for imparting rotative force on member 14 to effect the axial movement and for then rotating the member to start the engine, the restraining means is responsive to the rotative force to apply a counterforce to the member 14 varying in accordance with the value of the rotative force to restrain the member against rotation. The motor 50 drives an axially stationary rotative nut 86 through sun and planetary gearing and an adjustable multi-plate friction clutch 84. A hollow screwshaft 92 which is threaded into the nut 86 has a splined connection 94 with the member 14, whilst the latter is provided with a spring-loaded mesh rod 96, a radial flange 100 of which engages behind a similar flange 102 on the screwshaft. The mesh rod passes through a web in the member 14 and is held thereto by a nut 98 which also serves to compress a seal 99 located on another radial flange of the rod, against the rear surface of the web. The periphery of the jaw member shank has two diameters 18 and 20 that are joined by a ramp 22 and in the inoperative position of the starter the helival strip 32, secured at one end to the starter casing 62, engages the larger diameter 18 of the member 14. When the starter reaches the operative position, the strip 32 rides down the ramp on to the smaller diameter 20 and no longer opposes rotation of the member. The strip 32 winds itself about the member to a greater or lesser extent and thereby offers a variable counterforce to the rotation of member 14 depending upon the degree of congelation of the oil on the various parts of the starter. A seal ring 110 secured to the casing part 64 is maintained around an extension of the nut 86 by a garter spring.
