Title: Improvements in the production of surface designs on thermoplastic sheet materials
IPC: B29C35/12
Filed: 1947-09-23
Abstract: 642,148. Embossing thermoplastic sheet material. DUNLOP RUBBER CO., Ltd., and HINTON, J. J. Sept. 23, 1947, No. 25786. [Class 87 (ii)] [Also in Groups XI and XVI] A sheet 6 of thermoplastic material, e.g. polyvinyl chloride, polyvinyl acetate, polyvinyl butyrate, &c., is embossed with a pattern by pressing between a metal die 4 and a resilient pad 1 of sponge rubber, and at the same time heating the sheet in a high-frequency electric field applied by connecting the die 4 and metal gauze 3 covering the pad 1 to the poles of a suitable generator. The die 4 and pad 1 are supported by wooden backing members 5, 2. A sheet 7 of glazed linen or other high-loss insulating material, e.g. paper or rubber, may be inserted between the screen 3 and sheet 6. More power may then be used and the heating time reduced without danger of overheating. Instead of a raised or depressed pattern being produced by the die 4, the pressure and time of heating may be so limited that the surface texture only of the thermoplastic sheet in contact with the raised parts of the die may be modified, e.g. roughened or glazed according to the surface texture of the die. A sheet of glossy material, e.g. regenerated cellulose, may be interposed between the die and the sheet 6 and a glossy or semi-glossy design thereby produced on a normally matt sheet of polyvinyl chloride. According to the Provisional Specification, the pad 1 may be of rubber-impregnated fabric fixed to or separate from a wood backing itself fixed to a steel backing and the electrode 3 may be integral with the pad.
Patent GB-258711-A (GB)
IPC: E02F3/48
Abstract: 258,711. Marks, E. C. R., (Northwest Engineering Co.). Aug. 5, 1925. Scraping-apparatus.-In a drag-line excavator, the drag line is caused to act regeneratively to deliver power to the power means when, during paying out of the drag line under the tension of the load or the hoisting-cable, the drag line moves at a speed greater than that used in hauling in the drag line. A shaft 18, driven preferably by an internal-combustion engine, drives through gearing 19, 20, a shaft 21 loosely carrying the hoisting-drum 10 and a sleeve 23 ; the sleeve 23 carries a clutch drum 24 and the gear 20 carries a clutch band 25 which may be operated by an axially-movable spindle 40, bell-crank 34 and toggles, to engage the drum 24 and, through gearing 41, 42, 43, drive the drag-line drum 11 to haul in the drag line 15. By means of a similar band clutch 46, the hoisting-drum 10 may be driven from the shaft 21; a band brake 49 is also provided on the drum 10. The drag line drum has a band brake 51, and also a clutch drum 52 surrounded by a band 53, the ends of the band being connected to the ends of the unequal arms of a bell crank 56, Fig. 7, carried by a loose gear 54, an arm 59 pressed by a spring 60 normally holding the bell crank 56 to free the clutch band 53; when the drum 11, in paying out the drag line, exceeds a given speed, friction on the clutch band 53 causes rocking of the bellcrank lever 56, and consequently engagement of the clutch, the drag-line drum consequently delivering power through the gears 54, 45, and hoist drum shaft 21 to assist the prime power. When desired, the size of the hoisting-drum may be increased by bolting thereto an auxiliary split drum. The rotary table carrying the hoisting and drag line drums is rotated from a shaft 66, Fig. 10, through one of two friction clutches 75, bevel gearing 72, 73, 74 and a pinion 69 engaging a gear 70 fixed on the undercarriage of the machine; the clutches 75 are normally held out of action by springs 76 and are put in action by screws 77 acting through rods 79.

Suitable secondary amines are; those having N-substituents which are C 1-20  alkyl, alkenyl, and aromatic groups; secondary heterocyclic amines having 4-6 ring carbons; or a C 1-4  N-dialkanol or N-alkylalkanol amine. In the examples poly-p-hydroxy styrenes are aminated using formaldehyde (from paraformaldehyde) and dimethylamine, diethylamine, n-dibutylamine, diallylamine, pyrrolidine, piperidine, morpholine, diethanolamine or diphenylamine. The thus treated polymers are then either (a) formed into salts using HCl, H 2 SO 4 , HNO 3 , H 3 PO 4 , HCOOH, CH 3 COOH, CH 2 Cl-COOH or maleic acid; (b) quaternized using CH 3 Br, CH 3 I, allyl bromide, allyl chloride, octyl chloride, octadecyl chloride, benzyl chloride, chlorohydrin, dimethyl sulphate or alphachloro-p-nitrotoluene; or (c) cross-linked with dibromobutane, dibromomethane, dichlorobutane, beta, beta-dichlorodiethyl ether or p-xylylene dichloride. In Examples 39, 40 and 42 copolymers of phydroxy styrene with acrylic acid or acrylonitrile are dimethyl amino methylated and quaternized. In Examples 32 and 33 dimethyl amino methylated poly(p-hydroxy styrene) is quaternized with benzyl chloride and reacted with bisphenol diglycidyl ether to form a crosslinked product. The polymers may be moulded, to produce antistatic products, or coated on to paper.

Title: Improvements relating to flameproof connectors
Inventor: WILLFORD PERCY
IPC: H01R13/527
Filed: 1962-07-05
Abstract: 968,483. Two-part couplings. VICTOR PRODUCTS (WALLSEND) Ltd. July 1, 1963 [July 5, 1962], No. 25915/62. Heading H2E. An electric cable connector in which all the cores of the cable, with the exception of the earth core, are connected each to a contact, e.g. socket 9, has the contacts located in a mass of rigid insulating material 10, e.g. cured phenolic resin, having fitted round it a metal sleeve 12 connected via metal sleeve 21 and rings 16 and 19 (Fig. 3) to the earth core 3 of the cable, all the free space within the connector being filled with a flexible non-porous insulating material 28, e.g. a rubber compound which also extends partly along the sheath 5 and is sealed, e.g. vulcanized, to it. The power cores are screened by a series of copper wires 4 which are clamped between rings 16 and 19. Any spaces, such as 11, between each contact and the resin mass or 13, between the sleeve and the resin mass, are of such dimensions that a spark can not pass along them. The rubber compound fills the second and third sleeves 21 and 27 and ensures that no moisture can pass along the cores of the cable to any of the electrical connections. A projection 25 and a recess 26 are formed on sleeve 21 so as to mate with correspondingly shaped parts on a plug connector. The non- porous material when set is flexible enough to allow bending of the cable relative to the connector, and the rigid insulating material is such that it offers firm support to the metal sleeve. The earthed screening wires or shield may take any form since in all cases the shield can be clamped between rings 16 and 19 to provide earth continuity.
