Title: Improvements in and relating to the manufacture of reinforced side pieces for spectacle frames from thermoplastic material
IPC: B29D12/02
Filed: 1943-06-08
Abstract: 565,160. Moulding spectacle frame side-pieces, tooth picks, &c. POLACSEK, N. June 8, 1943, No. 9213. [Class 87 (ii)] Reinforcing wires to be embedded in the side-pieces are gripped at one end and held in position in the moulding spaces c by a clamping device comprising a bar h and strips i, the device being secured to the lower mould platen a by screw bolts j. The bar h has recesses n in which the wires k are held by projections o on the strips i. When the mould is opened, springs p lift the strips i from the bar h. The clamping device is held against the mould by means of an L-shaped bar s, which is secured to the mould by screws s<1> and has screws s<2> which, acting through a steel packing plate t, force the members i, h against the mould. In use, the platens a, b, being disassembled, are heated, a thin sheet of thermoplastic material is placed on the lower platen, the clamping device is secured in position with the wires resting on the sheet, a second thin sheet is placed on the wires, the upper platen is placed in position, and the mould is pressed in a hydraulic press. The clamping device may be arranged in the centre of the mould and loaded with two sets of wires extending on either side. Cavities may be pressed into the thermoplastic material (to receive the wires) before moulding. The wires may be stuck to the material by adhesive. The material may be cold and the mould hot or vice versa. The mould may be so contoured that tooth picks are moulded at the same time as the side-pieces.

Title: Treating sulphate solutions of thallium and cadmium
IPC: C25C1/16
Filed: 1934-03-23
Abstract: A solution of cadmium and thallium sulphates is electrolyzed, pure cadmium being deposited in the first stage; when the concentration of thallium in the solution has reached one-tenth that of the remaining cadmium, the cathodes are removed and the electrolysis continued with fresh cathodes for deposition of the remaining metals.  The cadmium-thallium deposit is dissolved in sulphuric acid calcined and the calcines dissolved in water. Sodium carbonate is then added to precipitate cadmium carbonate which may be dissolved in spent electrolyte and electrolyzed for cadmium.  Sodium sulphide is added to the thallium solution for precipitation of thallium sulphide which is dissolved in sulphuric acid and the solution boiled to remove excess of hydrogensulphide; traces of cadmium, lead or zinc are removed by making the solution alkaline with sodium carbonate; it is then electrolyzed for deposition of thallium.ALSO:Electro-deposited thallium is removed from the cathode in flakes and kept under water to prevent oxidation.  It is afterwards pressed and melted in graphite crucibles under a cover of oxalic acid and cast into bars.

Title: Improvements in door locks or latches
IPC: E05B65/22
Filed: 1940-05-25
Abstract: 542,763. Door latches. TUGWOOD, R. J. (Daimler-Benz Akt.-Ges.). May 25, 1940, No. 9236. [Class 44] In a latch, particularly for motor-vehicle doors, in which the bolt head has a longitudinal keeper-engaging movement and a transverse tightening movement, the connection between the bolt and door handles is such that one of the movements is completed before the other takes place. As shown the bolt head 34 is connected by arms 30 to a cylindrical part 36 with a pivot pin 39 slidably guided in slots 41, the head being shaped to provide an inclined surface 71 co-operating with a roller 58 carried by a slider 55 which is directly operated by an arm 61 on the spindle 64 of the handles 65, 66. The head 34 is biased to position in line with the slider by spring 43 and to shot position by spring 44 acting on the part 36. The slider is urged to shot position by spring 67 acting on the handle spindle. In use to fasten the door the bolt is retracted by the handle, the door closed, end the handle released. Spring 44 first shoots the head 34 into the keeper 75 as in Fig. 4, spring 67 then continuing movement of the slider so that roller 58 acting on surface 71 moves the head 34 laterally to the tightened position, Fig. 3, urging the door on to its seating. The movements occur in reverse order when the handle is operated to effect release. In a modification the inclined surface is formed on the slider and the roller is mounted on the bolt head. In another form the inclined surface is provided on the lock casing and the slider has a pivoted end-piece carrying the roller, this endpiece being swung laterally and communicating its lateral movement to the bolt head. In further modifications the slider may have two rollers offset or of different diameters so that one engages the casing and the other the bolt head. The roller arrangement may be replaced by a link connection between slider and bolt head, the link being inclined at a small angle to the slider movement during the longitudinal operation and then swinging to a greater angle to move the head laterally on further movement of the slider. Fig. 8 shows an arrangement with the handle spindles 86, 96 out of alignment such that movement of one handle does not affect the other. The slider is operated by a swinging arm 82 connected with arms 87, 97 on the spindles by links 90, 98 pivoted to arm 82 at 89, 102. When handle 65 on spindle 86 is depressed link 90 swings arm 82 clockwise about pivot 102, and when handle 66 on spindle 96 is depressed, link 98 swings arm 82 clockwise about pivot 89, the slider being retracted in both cases. In a modification the links are replaced by pins on the arms 87, 97 having sliding engagement in arcuate slots formed in arm 82. In a further form arm 82 carries a toothed member opposite edges of which are engaged by pivoted toothed sectors which are themselves, respectively, rotated by toothed sectors on the handle spindles. In this form the toothed member on the arm fulcrums on one pivoted sector whilst the other is being operated to rock the arm.

Title: Improvements relating to brakes particularly for vehicles adapted to run on rails
IPC: B61H13/02
Filed: 1924-04-11
Abstract: 227,328. Swiss Locomotive & Machine Works. March 14, 1924, [Convention date]. Hand actuation; compensating for wear. - A device for taking up the slack in the hand-operated brake screw 3, rigging 2 and brake blocks 1 caused by wear of the latter, comprises a screwed spindle 8 parallel and geared to the brake screw 3 by gear wheels 6, 7, the latter acting as a nut to the rod 8 which can move axially but not rotate. This rod 8 carries loosely a member 9 having a bolt 10 co-operating with a fixed rack 11. When the brake is released the rod 8 moves down until the collar 8<1> thereon abuts against the bottom of the member 9 but when the brake is applied the collar 8' rises and, if sufficient wear has occurred, rises sufficiently to carry the member 9 up with it until the bolt 10 takes over the next higher tooth of the rack, thus limiting the stroke of the brake screw 3. When the limit of the device is reached the pin 12 is undone, the rack is swung about the pin 13, the member 9 is returned to its lowermost position and the pin 12 is replaced, the slack being taken up in the rigging itself. The brake may be actuated independently by the hand screw 3 or by a compressed air, or a vacuum brake cylinder 4, neither of which interferes with the other. The fixed point of the rigging is in the screw 3 or at the point 5 according as the mechanical brake 4 or hand brake 3 respectively is used.
