Title: Method of Purifying Contaminated Plating Solutions.
Inventor: GERHOLD CLARENCE GEORGE
IPC: B01J23/86
Filed: 1967-07-06
Abstract: 1,195,887. Plating with noble metal. UNIVERSAL OIL PRODUCTS CO. July 6, 1967 [July 7, 1966], No.31185/67. Headings C7B and C7F. [Also in Divisions B1 and C1] Noble metal (i.e. Ru, Rh, Pd, Os, Ir, Pt or an alloy of two or more of these metals) is electroplated or immersion plated from a plating solution on to a solid metallic alloy base selected from Ni- Cr alloys and Ni-Cr-Fe alloys, e.g. to make material which catalyses the combustion of inflammable vapours. The plating solution becomes contaminated and is purified by intermittently or continuously contacting it with a cation exchange resin and thereby removing metallic alloy base material contaminants from the plating solution with minimal accompanying removal of noble metal. Specific cation exchange resins are mentioned. The resin can be used in the form of powders, chips or beads. In examples, a metallic alloy base in the form of screen, wire or mat is cleaned in a hot solution of sodium orthosilicate with a surface active agent and is plated with Pd from baths containing palladium chloride and HCl. For example, (a) spongy Pd is electroplated at 71-77‹ C using graphite or Pd anodes or (b) amorphous Pd is plated by emmersion coating at 82‹ C with no electric current applied, the Pd replacing Ni and/ or Cr in the metallic alloy base. The plated alloy is rinsed and then heated to 316‹ C in an air stream containing hexane whereupon surface combustion takes place thus conditioning the Pd coating for service and increasing its tenacity to the base metal. In use, electric heating current is passed through the coated material to catalyse the combustion of vapours such as are produced when baking enamels and varnishes.

Abstract: 1430967 Doors BERNARD CALAIS SARL 29 June 1973 [3 July 1972] 31190/73 Heading E1J A door assembly for a wall opening 1 comprises a door 3 with sealing means, and two suspension rollers 6, 7 movable along a rail, sections 9, 10 of the rail being movable out of alignment with fixed parts 5a, 5b, 5c of the rail to carry respective rollers downwardly and towards the wall on closing of the door. Each movable section has guide tongues (12, Fig. 2) projecting from its ends to slide in grooves (11) in the ends of adjacent fixed sections. Each movable section carries a stop plate (13, Fig. 4) to limit its movement by abutment against the ends of the adjacent fixed sections or against a yoke (14) secured between and below them. The movable section is biassed into its aligned position by spring (15) engaging stop plate (13) and the head of a screw (16) secured to a fixed section. The ends of the fixed sections have cut-outs (18, Fig. 2) with inclined surfaces (19) which guide the roller flanges as they move downwardly. A catch (Fig. 2) has a spring biassed wedge (23) holding section 9 in its upper position and is releasable by a plate (27) on a roller bracket.

The pigment to be treated may be titanium dioxide (optionally having small quantities of hydrated metal oxides, e.g. hydrated alumina or a hydrated oxide of titanium, on the surface thereof), a composite or coloured pigment containing titanium dioxide, silica, blanc fixe, lithopone, barium carbonate, zirconia, zinc oxide, aluminium oxide, chrome yellow or phthalocyanine. The macromolecular material is preferably a synthetic polymer and may be a homopolymer or a graft or block copolymer, and preferably contains units from an acrylic ester and acrylic acid. The numerical ratio of organophilic units to hydrophilic units may be in the range 1:4 to 4: 1. A macromolecular material wherein the group Y is -CO 2 H may be treated with a hydroxyalkylamine (e.g. triethanolamine) prior to use. The pigment particles may be dry before treatment or may be in the form of a paste, pulp or slurry with water. The macromolecular material is preferably applied in the form of a solution thereof in an alcohol (e.g. isopropanol) and/or water. The treatment, which involves thorough mixing, may take 5-30 minutes, and the particles are subsequently dried to remove water and solvent. The quantity of polymer used may be 0À01-5À0 wt. per cent (based on the pigment), and at least part of this is retained on the pigment particles.

Abstract: 208,872. Fattorini, A., and Stenberg, E. Nov. 16, 1922. Portable checking and recording clocks for pigeon races &c.-An apparatus for recording the time of arrival of pigeons in a race comprises four paper or like dials a - - d representing days, hours, minutes and seconds actuated by the clock mechanism i and disposed in front of a plate e covered by a detachable glazed front, a pricker mechanism mounted on a slidable and rotatable shaft r at the back of the plate e and actuated by the rotation of a pigeon ring box k which is mounted below the clock mechanism and intermittently rotated by a hand operated plunger x, and a locking lever g adapted to be moved to lock and release the lid of the casing by means of a notched disc on the ring box, means being provided to record said movements.

Abstract: 883,166. Chucks. LANDIS TOOL CO. Sept. 15, 1959 [Sept. 15, 1958], No. 31392/59. Class 83 (3). [Also in Group XXIII] An annular workpiece 16, Fig. 1, is clamped externally of the bore between a magnetic or other face-plate 8 and a clamping device comprising a stationary bearing member 9 having an axial chamber 15 containing a rotatable piston 22 having at one end a work-engaging device 29, and means for applying fluid pressure to the piston to displace the device 29 towards the face-plate. The front portion of the piston 22 has an enlarged portion 26 having a flange 27 located in a recess 25 formed in the front face of the member 9 which is carried in the machine by a loading arm 10. Extension 18, 21 of the member 9 initially support the workpiece which is located slightly eccentrically of the face plate by two angularly spaced bearing pads 19, 20, Fig. 2. The edge 34 of the work-engaging member 29 is bevelled and hardened or faced with a hard material to provide a wearing face. Compressed air or other fluid pressure is supplied via a manifold 13 and an axial duct 12 to bear on the conical face of the piston 22, the full diameter of which provides a clearance of 0.0012 inch to 0.0017 inch between it and the cylinder walls so that air escapes around the piston to provide a fluid bearing whilst retaining sufficient pressure on the piston to clamp the workpiece against the face plate. A larger clearance is provided between the flange 27 and the wall of the recess 25 so that, as grinding progresses the work may shift away from the supports 19, 20, as its diameter decreases, towards the wheel without affecting the engagement between the clamping device and the workpiece the piston 22 permitting the slight pivotal movement required without increasing the clearance between it and the cylinder.

Abstract: 856,829. Binaural pick-ups. BAYLIFF, R. W. Sept. 18, 1958 [Oct. 8, 1957], No. 31481/57. Class 40 (4). A binaural pick-up has an armature 10 mounted so that it can move vertically or laterally, as viewed in Fig. 1, so as to influence the flux through coils 29 and 17, respectively. The armature is carried by a leaf-spring 11 and a wire (not shown) in the manner described in Specification 748,982. Lateral movement of the armature affects the flux between the polepieces 18 of a magnet 33 so inducing a current in a pancake-shaped coil 17. Vertical movement affects the gap 31 of a second magnetic system so inducing a current in coils 29. The magnetic systems are adjustable (Figs. 3 and 5, not shown) with respect to the armature. For use with combined lateral and hill-and-dale records the coils 17 and 29 feed the appropriate channels separately. For use with records in which the two channels are recorded at angles of 45 degrees to the vertical the outputs of the coils are added and subtracted to reproduce the signals. In this case the coils 29 may be duplicated and the circuit is then as shown in Fig. 7.
