Patent GB-699394-A (GB)
Title: Improvement in patterned detergent and process for making same
IPC: C11D13/18
Filed: 1951-12-05
Abstract: <PICT:0699394/III/1> In extruding soap which is sensitive to pressure e.g. floating soap, for example by the process described in Specification 555,034, the extrusion orifice is designed so that the broader surfaces of the extruded strip are configured lengthwise, as shown in Fig. 11.  The edges of the ends of the base cut from the strip may be rounded or chamfered.  Emblems may be impressed on the face of the bars, the dies for which, particularly, in the case of floating soap, are positioned so that only their raised portions press on the soap, which is thus compressed over a small surface area to reduce local darkening of the soap to a minimum. Specifications 330,886, [Class 84], and 566,756, [Group V] also are referred to.
Patent GB-957430-A (GB)
Title: Improvements in articles such as brushes or buffs
IPC: B24D5/02
Filed: 1960-08-17
Abstract: 957,430. Polishing buffs. OSBORN MANUFACTURING CO. Aug. 17, 1960 [Aug. 18, 1959], No. 28538/60. Heading B3D. [Also in Divisions B5 and D1] A polishing buff or mop is formed of random fibres or filaments preliminarily bonded together where they contact one another so as to leave interstices which are at least partly filled with synthetic resin material. The fibres used may be of tampico, sisal, cotton waste, rubberized fibres, glass, rayon, nylon, nylon with adherent abrasive, or metal (such as nickel, cobalt-base alloys, titanium, molybdenum or steel). The preliminary bonding may be effected by spraying a batt of the randomly-arranged fibres with a thin layer of rubber latex over a suction chamber, or, when the fibres are of metal or synthetic material, by fusion at the points of contact. The filler may be of foamed polyurethane or polyvinyl chloride or of phenolic, silicone or epoxy resin foams and may incorporate any suitable abrasive. The filler may wholly or partially fill the interstices and, if desired, may provide a cellular structure of which 90% is open. A buff may be formed by stamping a circular blank from a batt of the fibres which has been treated as above or by winding a strip of such form into a spiral. Alternatively, the inner annular part of a circular buff may be formed of a batt constructed as described and an outer annular part consisting of a polyurethane foam incorporating abrasive but no fibres. The buffs may be stamped from two superposed sheets of the preliminarily-bonded fibres fed from two rolls 34, 35, Fig. 7, and pressed together by pairs of rolls 40, 41 to cause impregnation of a polyurethane filler which, together with a catalyst, is fed on to the upper surface of the lower sheet before it reaches the rolls 40. Following the rolls 41, the sheets pass through bubble-control rolls 42, 43, a pre-baking oven 44, stamping machine 45, and final baking oven 47. Buffs may similarly produced using one preliminarily-bonded fibre sheet only. In a further arrangement, pairs of superposed blanks are simultaneously blanked from separate sheets of the preliminarily bonded fibres and fed by a conveyer to a point where the filler and catalyst are applied to the separate blanks; the two blanks so treated are sandwiched together, with the filler intervening, by passage between rolls or through a press, and are then fed to a baking oven. A circular buff may be formed by placing a batt of the preliminarily-bonded fibres in a rotating mould 63, Fig. 10, into which the filler is introduced from a tank 70 so as to fill the interstices by centrifugal action. Abrasive material may be subsequently or simultaneously supplied to the mould and foaming of the filler may be effected by adding a catalyst and water.

Title: Improvements in wireless receivers
IPC: H03J7/04
Filed: 1935-10-07
Abstract: 465,515. Valve circuits for wireless reception. ROBINSON, J. Oct. 7, 1935, No. 28609/34. [Class 40 (v)] A wireless receiver is automatically brought into exact tune with a desired signal by a control potential derived by rectification from one of the receiving stages, and applied to vary the grid bias of a variable-mu valve associated with the tuning circuit of the receiver. The Figure shows a superheterodyne receiver in which part of the intermediate frequency energy is rectified at 17 and amplified at 18. The rectified potentials are then applied through a change-over switch 34 to the grid of a variable-mu oscillator 13 and vary the oscillator frequency in such sense as to bring the receiver into exact tune. The switch 34 is operated by an arm 35 in accordance with direction of rotation of the tuning knob 30 of the ganged tuning elements of the preselector 10 and local oscillator circuit 12 ; the automatic control is thus operative for either direction of rotation. The oscillator may have a fixed initial bias which is opposed by the applied control potentials ; by this arrangement, the control potential may be arranged to be a maximum at a predetermined frequency difference from exact tune. Specification 407,057 is referred to.

Abstract: 291,471. Coles, S. O. Cowper-. Nov. 20, 1926. Indiarubber, electrodeposition of. - In the electrophoretic deposition of rubbar from aqueous dispersions, the deposition is effected intermittently, to allow of the dispersal of any gas bubbles that have formed. The current itself may be intermittent, or the anode may be removed periodically from the bath, or these methods may be used in conjunction, the current preferably flowing only when the surface is entirely immersed. In addition, the anode may be caused to vibrate or rotate during deposition. Suitable times are. two seconds immersion with a current density of 10 amps. per sq. foot and one second exposure to the air; or two seconds immersion at 20 amps. per sq. foot followed by two seconds exposure. During exposure the deposit may be acted upon by a current of hot air. The process may be carried out by employing rotating drums partly immersed, or by mounting mandrels on a revolving cage, or by mounting the moulds on a reciprocating frame. Numerous other features are claimed in conjunction with the above process. These include, the use of metal moulds such as those of cadmium or zinc or zinc coated iron or aluminium, which may be dipped in adhesive such as gum arabic or gum tragasol, or coated with plumbago, french chalk, etc.; the addition of vulcanizing, colouring, compounding, &c. materials to the latex; the passing of sulphuretted hydrogen through the latex to facilitate vulcanization during deposition; cathodes approximating to the shape of the anode; reducing the ammonia content of the lattex by the addition of acetic acid, and adding further ammonium acetate; coating the article with metal by converting the anode into a cathode in another bath or in the same bath if a metallic solution has been added to the latex; spraying metal dust on to the rubber during the exposed periods; coating two metal plates by immersing them an latex and periodically reversing the current; coating a metal plate by making it an anode and causing a jet of latex from a cathode nozzle to impinge upon it: a depositing cell with a compartment in which rotates a propeller drawing latex from the bottom. and returning it over a weir.
