Title: Process for the production of coated substrates
IPC: C08J3/215
Filed: 1962-11-12
Abstract: Substrates are coated by application thereto of a dispersion which contains synthetic plastics, wherein electrically conductive carbon black is converted with the aid of a wetting agent into a dispersion, the carbon black dispersion is combined with an aqueous dispersion of a synthetic plastics material known per se, and the carbon black-plastics dispersion is applied to the support and is then dried and fixed in known manner, the carbon being present in an amount of at least 5% by weight e.g. 5-30% by weight, based on the weight of the plastics material.  The coating may be produced by the pasting method using a mixture of (a) polyvinyl halides and/or copolymers with predominant proportions of vinyl halide, (b) plasticizers, (c) fillers, stabilizers and other known additives and if desired (d) volatile organic solvents or diluents, wherein an electrically conductive carbon black in the form of an aqueous dispersion containing a wetting agent is introduced into the plastisols or organosols known per se in a proportion such that at least 5% by weight of the carbon black is present based on the weight of vinyl compound, this mixture being applied to one or both sides of the support possibly in several working steps, and dried and gelled by the action of heat.  The substrate may be a woven or knitted fabric, fleece, felts, foil, textile and non-textile flat and web-like support, of natural or synthetic fibres or yarns e.g. polyesters, nylon, cotton, paper, cardboard.  The aqueous carbon black dispersion may consist of 10-30% by weight, e.g. 18-25%, of electrically conductive carbon black, about 2% by weight of a wetting agent, e.g. an anion-active wetting agent, and the remainder consists of water. The carbon black dispersion may be incorporated into the plastisol or organosol slowly and with low shearing stress in quantities up to 1 : 1.  Polyvinyl halides and copolymers specified are homopolymers of vinyl chloride, fluoride or bromide, and copolymers thereof with vinyl esters such as vinyl acetate, propionate, bromopropionate and chloroacetate, vinyl alcohol, vinyl ether and thioether, vinyl chloracetal, vinyl acetylene, acrylic and methacrylic acids and their esters, vinylidene chloride and fluoride, styrenes, acrylonitrile, butadiene, isoprene, chloroprene, isobutylene, ethylene, propylene, maleic and fumaric acid esters.  Examples of suitable extenders, fillers, plasticizers, wetting agents and adhesion promoters are given. The coating may be applied by dipping, casting or brushing.  A primer coat e.g. of polyvinyl chloride, may be present.

Abstract: 1519160 Injection moulding foamed crosslinked articles SUMITOMO CHEMICAL CO Ltd 29 Oct 1975 [30 Oct 1974] 44551/75 Heading B5A Articles of a cross-linked foamed ethylenic polymer are made by plasticizing a mixture of the polymer with a blowing agent and a crosslinking agent without decomposition of either agent, holding the mixture in a holding chamber at a temperature and for a time sufficient for the agents to decompose, but without foaming of the mixture, and finally injecting the mixture into a mould where it foams to form the desired article. It is preferable for the temperature of the plasticizing step to be below the one minute half life temperature of the cross-linking agent plus 20‹ C. and for the holding chamber to be at a temperature below that temperature plus 70‹ C. To obtain cross-linking sufficient to give a gel per cent of greater than 30% in the finished article it is necessary, for the temperature ranges quoted above, for the greatest distance between the wall of the holding chamber and a point inside the chamber to be 25 mm. when the chamber is hollow and 15 mm. when the chamber is annular. The polymer may be a homopolymer of ethylene, a copolymer of ethylene with a comonomer, a mixture of such, or a mixture of such with another, miscible, polymer. The preferred polymer is an ethylene vinyl acetate copolymer. In one embodiment (see Fig. 1A) working material is plasticized by a screw 1 in a heated cylinder 2 and passed through a heated cylinder head 3 into a holding chamber (5) of circular crosssection. The chamber is heated by heaters 4.2 and the foamed material is fed to a mould through a heated nozzle 8 having a spring 6 biased valve needle 9. In a second embodiment (see Fig. 2A), the holding chamber is annular and contains a centrally disposed heated core 4.2A.

Title: Cooking device with proportioning control
IPC: A47J27/00
Filed: 1965-10-21
Abstract: 1,126,050. Cooking apparatus. SUNBEAM CORP. 21 Oct., 1965 [29 Dec., 1964], No. 44633/65. Heading A4D. [Also in Division H2] In a portable cooking enclosure, having an electric frying pan as base and a deep broiling cover containing an electric heating element, the upper and lower heating elements are energized separately through a plug-in control unit. The control unit is adapted to operate either heater continuously or, for baking, both heaters are operated in alternating periods of variable duration. For continuous operation of heater 62, detachably mounted in aluminium broiler cover 52, the upper contacts of micro-switch 312 are held closed by follower 310 riding wholly within clover leaf depression 256e of cam 256. For continuous operation of heater 34, secured to the base of aluminium frying pan 32, the follower 310 rides on the raised rim of cam 256, as shown in Fig. 12. All components, shown in Figs. 12 and 14, except heaters 34 and 62 are housed in the control unit casing (102 ,  Fig. 1, not shown). An electric clock movement 128 rotates cam 230a through one complete revolution in four hours and cam 256 in four minutes. Follower 310 is radially adjusted, on cam 256, by rotating pinion 276 by means of knob (294). At intermediate positions, the rotational movement of the cam imparts an up-and-down movement to follower 310 which accordingly causes alternate energization of heaters 34 and 62 through the operation of switch 312. The clock movement 128 also provides a timer control which opens micro-switch 242, by means of cam 230a, at the expiry of the cooking period. The cam 230a is turned through the appropriate angle, to allow switch 242 to close, at the beginning of the cooking period. The maximum temperature which may be reached during the cooking period is determined by an adjustable thermostatic control, which switches off the heater by opening the contacts 189, 190. The temperature is detected by a probe 172 fitting, with good thermal contact, in a socket in the frying-pan heater mounting. The probe 172 contains a bi-metallic contact operating strip. A pilot lamp L is extinguished when the heaters are switched off. The control unit is detachably connected to the frying-pan and cover by pin and socket connectors of heaters 34 and 62 and the socket holes are covered by plastic diaphragms, having star-shaped slits, which are opened by the passage of the pins. The broiler cover (52) is provided with an observation window (60) and ventilation aperture (68).
