Title: Method of catalyst manufacture
IPC: B01J23/882
Filed: 1959-12-03
Abstract: Cobalt-molybdenum-alumina catalysts suitable for hydrogenation reactions, e.g. hydrodesulphurization, are produced by mixing alumina with cobalt and molybdenum compounds which form oxides on heating, a carbon-containing material and 2,5-10% (based on weight of finished catalyst) of nitric acid (63% HNO3) or mole equivalents of other strong mineral acids, adding water to form an extrudable paste, extruding through an orifice to form shaped bodies and calcizing at 600-1000  DEG F.  Alternative acids are hydrochloric, sulphuric and oxalic.  Specified carbon-containing materials are aluminium stearate, corn starch, wood flour, graphite, lamp black and synthetic resins such as polyvinyl acetate.

Abstract: 880,188. Tin plate. UNITED STATES STEEL CORPORATION. Dec. 3, 1959 [Dec. 11, 1958], No. 41157/69. Class 41. Electro-tin plated steel sheet after stabilizing with chromic acid solution, is treated with a reducing agent, e.g. an aqueous dilute solution of citric acid or SnCl 2 . The product is more easily coated with lacquer and "eye-holes" are prevented. In a suitable plant, tin plate in the form of continuous strip is, after heat treatment and quenching by water spray, fed into an electrolytic bath 11 containing chromic acid, washed in a bath 12, and then passes into a bath 13 containing about 1% of citric acid or acidified SnCl 2  solution, where it is treated at 160 ‹ F. for up to 1 second, and is then dried and oiled before coiling. It is stated that the reducing bath 13 removes any free hexa-valent chromium.

Title: Supply circuits for electromagnets
IPC: H01F7/18
Filed: 1975-10-08
Abstract: 1476102 Supply circuits for electro magnets LA TELEMECANIQUE ELECTRIQUE 8 Oct 1975 [28 Oct 1974] 41211/75 Heading H2H A supply circuit for energizing an electro magnet from an A.C. or D.C. source comprises a contact o, a switch TR1 whose state depends on the position of a movable armature M2 of the magnet with respect to its fixed core M1, a main winding M 1 , a holding winding M 2  and a bridge rectifier D1-D4. The switch TR1 as shown is a triac which, when the contact o is closed, is triggered into conduction by a pulse generator including a unijunction transistor T3 supplied by a stabilized voltage from a Zener diode D9. The winding M1 is energized and the armature M2 is attracted to the core M 1 . At the end of the movement the closing of the magnetic circuit causes a high voltage across the holding winding M 2  which, after a delay determined by an R-C circuit R2-C1, is detected by a threshold circuit including transistors T 1 , T 2 . The transistor T 2  conducts and short circuits the Zener diode D9 to prevent triggering of the triac. The holding winding remains energized via the contact o, a diode D5 and a resistor R1.

Title: Improvements in or relating to the stiffening of shoes
Inventor: HAWKES JOHN ARTHUR
IPC: A43B23/16
Filed: 1962-11-10
Abstract: A stiffener suitable for incorporation in the toe or heel end portion of a shoe upper is made from an elastomeric copolymer of ethylene and an alkyl acrylate, preferably ethyl acrylate.  The copolymer may be used as follows: (a) it may be applied directly, as a molten mass, to the inner surface of the outer integument of the upper, (b) it may be injection or compression moulded to the required shape, or (c) it may be extruded into a sheet from which stiffener blanks may be cut, the edges of the blanks then being skived.  In cases (b) and (c) an adhesive may be applied to one or both surfaces of the stiffener, depending on whether the shoe is lined or not, and the surfaces to which adhesive is applied may be oxidized, for example by the action of chromium trioxide and sulphuric acid, by an oxidizing flame or by corona discharge.  In case (c) a copolymer may contain a filler such as wood flour, cotton, viscose or other short fibres, which are exposed along the skived margin of the stiffener.  The adhesive composition may be a heat or solvent activatable cement such as neoprene, a polyacrylate or polyvinyl acetate or a pressure sensitive adhesive such as polyisobutylene or an aqueous emulsion of natural rubber and a resin ester in which case the coated surfaces are covered with a strippable protective paper.  When making an unlined shoe the inside surface of the stiffener may be laminated to a sheet of decorative materal e.g. flocked fabric.

Abstract: 1, 025, 889. Automatic distillation plant. G.& J.WEIR Ltd. Oct. 9, 1964 [Oct. 31, 1963], No. 42958/63. Heading B1B. The quantitative input of heating medium to the evaporator 3 of a distillation plant for water is controlled to maintain constant the output of distillate by an automatic control box 6 connected to valve 4 in the supply-line 5 of heating medium to the evaporator, the control box being actuated by an orifice plate 1 in the output line 2 of the distillate withdrawn from the condenser 10 by pump 9. Valve 4 may be pneumatically-controlled by an air-line 7 joined to one end of a pivoted lever in the control box, the other end of the lever being acted upon by the distillate pressures just upstream and downstream of the orifice plate 1. The heating medium may be steam, hot water or flue gases. The casing 12 of the still is put under vacuum by air pump 11. When the vacuum has been established the diaphragm valve 24 and air-lines 19,19<SP>1</SP> will operate to open the valve 22 in the feed-water line 20, and the valve 23 in the distillate-line 2. Diaphragm valve 24 also causes the opening of valve 4 by an amount determined by the pressure-difference across orifice plate 1. The height of water being distilled extends just above the upper surface of evaporator 3, the excess water flowing over weir 13 into passage 14, and being withdrawn from the still by ejector 16. This ejector is operated by water fed through line 17 and pneumatically operated on-off valve 18, which is connected to valve 24 by air-line 19. The salt content of the distillate is measured by device 25, and if the value is too high, the distillate is discharged through dump valve 27.
