Patent GB-572985-A (GB)
Title: Improvements in or relating to the treatment of plastic surfaces
IPC: C23C18/24
Filed: 1942-02-20
Abstract: The surfaces of objects or masses made from or containing resinous polymerization or condensation products containing an aromatic nucleus are rendered hydrophilic by superficial treatment with liquid concentrated sulphuric acid, furing sulphuric or chlorsulphonic acid or with the vapours of such acids or sulphur trioxide.  Specified resins are phenol-aldehyde resins and polymers of styrene, coumarone and indene and copolymers derived therefrom.  Control of the treatment is effected by variation of time and temperature and by varying concentration of vapour, when used.  Treatment may be applied to the whole surface or to selected areas.  The treated surfaces may be dyed and may serve for anti-misting or deicing purposes, for the deposition of metals from solution or by low vacuum volatilization, as printing-blocks for aqueous inks, for the internal or external surfaces of windscreens, cockpit covers, &c. particularly those sprayed with an anti-freeze solution, and for glueing to other surfaces.  In examples: (1) a sheet of polystyrene is exposed to the vapours of fuming sulphuric acid, washed, dried and cut into discs to form respirator eyepieces; (2) a sheet of polystyrene, treated as in example (1), after washing, is immersed in and gradually withdrawn from a solution of Bismark Brown to form colour wedges; (3) a cast plate of phenol-formaldehyde plastic is surface treated with chlorsulphonic acid, washed, dried and bonded to a wooden panel with hot glue; and (4) a compound screen suitable for use under icing conditions is obtained by securing a sheet of polystyrene, treated as in example (1), to marginal spacing strips of polymethylmethacrylate in turn secured to a sheet of polymethylmethacrylate.

Filed: 1956-01-24
Abstract: 796.831. Drink-dispensing apparatus. STILL & SONS, Ltd., W. M. Jan. 24.1957 [Jan. 24, 1956], No. 2304/56. Class 27 Automatic coin-freed apparatus for dispensing hot beverages comprises a cabinet 10 housing refrigerated containers 12, 14, 16, 18 for various liquids, an electricallyheated hot water container 28, mechanism for feeding cups into a filling position 54, and coin-actuated mechanism serving to close an electrical circuit and thereby effect the cup-feeding and liquid-dispensing operations after the selection of liquids by one or more switches 42. The containers 12, 14, 16, 18 which may contain milk, concentrated liquid chocolate, sugar syrup, and concentrated liquid coffee, respectively, are arranged with solenoid-operated valvecontrolled passages 34, 36, 38, 40 communicating with a common trough 32 which is also connected with delivery spout 30 of the hot water container 28. In operation, switch 42 is moved to one or other of its five positions A, B, C, D, E corresponding to the required beverage, and, upon insertion of a coin in the slot 8, a motor driving the cup-dispensing mechanism is started so that a cup is fed from a stack 58 to the filling position 54. After a short delay, the appropriate solenoid-operated valves are opened, the duration being controlled by cam-operated time switches, and the selected liquids flow into the trough 32 and thence into the cup; after a pre-determined rotation of the cam shaft, which is driven by the cup-dispensing motor, the solenoids are de-energized and the dispensing of the liquid ceases. A float-controlled solenoid operated valve 66 controls the entry of cold make-up water into the hot water container 28, and a switch prevents the continued entry of the cold water after the last cup has been dispensed. The cupdispensing mechanism may be constructed as described in Specification 606,217.

Filed: 1975-01-21
Abstract: 1493532 Making cable harnesses; machine tool control; drilling machines WESTERN ELECTRIC CO Inc 21 Jan 1975 [23 Jan 1974] 2513/75 Headings B3A B3B and B3C [Also in Division H2] A plurality of wires 21 from sources 14 are laid out on a board 12 by a corresponding number of wiring heads 16, each of which in turn is moved over the board while its associated wire is anchored. As shown, a positioning device 17 is traversable vertically by lead screw 54 and horizontally by motors 56, 59 undo the control of a punched tape unit 18. Each head 16 is normally located on a support 11b, Fig. 3, by a spigot and socket 43, and retained by a permanent magnet 42 and feromagnetic insert 16a. Initially, each wire is fed through tension rolls and a tension detector which can stop operations if the wire breaks, through guides 24, 27, round a capstan 28 on the respective head, through guide 29, and is anchored manually on pin 32. To lay out a wire of a wire harness the device 17 is positioned automatically over a lug 16b on the respective head, and secures it by a solenoid or air motor operated pin 44, or by an electromagnet more effective than magnet 42. The postioning device 17 then removes the head from support 11b, winds the wire round achor pin 19a, lays the wire out as required, and then winds it around pin 19a again or another anchor pin 19b as the case may be, and returns the head to its starting place. The wire is then severed between pins 32 and 19a, and between the final anchor pin and guide 29. While the head is travelling, capstan 28 effects a positive feed of the wire in predetermined fashion. On completion of all wiring, the board is removed and replaced, and the harness completed. The positioning device 17 may be replaced by a drill so that the apparatus can be used to make holes for the pins in a board. More than one harness may be laid out at a time.

Abstract: 662,342. Primary batteries. GENERAL ELECTRIC CO., Ltd., and NATTRASS, W. A. Feb. 1, 1950 [Feb. 1, 1949], No. 2772/49. Class 53. [Also in Group V] The annular casings of the cells of a primary battery in which the cells nest one within another as described in Specifications 549,036 and 617,669, are made of a thermoplastic material such as bitumen or wax which is capable of flow in the completed battery so that the joints between the cells are proof against leakage of electrolyte. The casings may be made by dipping a tool shown in Fig. 1 into liquid bitumen or wax. The tool comprises a brass block 1 the lower end of which, is shaped to give the required inside dimensions of the casing which is stripped from the block after it has been removed from the liquid bitumen &c. The lower part of the block is hollow to provide an opening in the bottom of the casing. Cooling water may be circulated through pipes 5, 6 and a closed chamber 3. A zinc plate may be moulded in the bottom of the casing by temporarily attaching it to the bottom of the block by means of a vacuum provided by a pipe 7. The greater part of the under surface of the zinc plate is protected from contact with the bitumen by a spring- pressed pad projecting upwards from the surface of the bitumen.
