Title: Improvements in method of making closed cell expanded rubber or like thermo-setting composition by internally developed gases
IPC: C08J9/00
Filed: 1938-08-18
Abstract: 518,517. Closed cell sponge rubber &c. EXPANDED RUBBER CO., Ltd. Aug. 18, 1938, No. 24348. Convention date, Aug. 18, 1937. [Class 70] A closed-cell gas-expanded rubber or a thermo-setting material is prepared by mixing rubber &c. with ingredients to generate gas, subjecting the mix to a pressure of inert gas to prevent escape of gas from the rubber when heated, heating to generate gas, and cooling the mix while still maintaining the external gas pressure. On release of the pressure, the material may become further expanded and additional expansion may be obtained by the use of reduced pressure. In the case of a rubber product, vulcanization is completed by further heating. As substances which generate gas may be used a mixture of sodium nitrite and ammonium chloride, which generates nitrogen, or diazoaminobenzene or diazoaminomethane which on heating liberate nitrogen and leave amine compounds which act as anti-oxidants for the rubber. The rubber may be expanded by the vapours generated from an oil such as paraffin, or by hydrogen sulphide generated by the action of sulphur or rubber at 330‹F. or above. Agents which generate chlorine or hydrochloric acid may be used, and in these cases the rubber becomes chlorinated or hydrochlorinated. Charcoal containing occluded gases such as carbondioxide, nitrogen, helium, &c. may be used, and the mix may be heated by a high-frequency current or by the resistance of the mass to an electric current. The process may be applied to phenol formaldehyde, acrylic acid or vinyl resins, and to chlorinated or hydrochlorinated rubber, alone or mixed with rubber. Specification 358,967 is referred to.

Abstract: 296,070. Associated Telephone & Telegraph Co., (Assignees of Stehlik, R. F.). March 14, 1927, [Convention date]. Divided on 287,079. Drawings to Specification. Semi-automatic exchange systems.-One wire of an automatic-manual junction is connected to battery at the outgoing end through a relay which marks the junction busy when ground is connected to the wire at the incoming end. The relay is disconnected from the junction and energized locally when the junction is taken into use. The ground connection is effected in some cases through a winding of the line relay which is unable to pull up in series with the busying relay. The line relay is initially operated over the other wire and subsequently held over both. The busying relay is operated when a fuse blows, when all the call-indicator registers but one available to the junction are busy, when the hunting switch that associates the junction with a register is in motion, when a busying key is thrown by the operator or when the relay group in which the junction terminates is being tested. The system described is identical with that described in Specification 287,079.

Title: Dispersions of fluorine-containing polymers
IPC: C08F6/20
Filed: 1947-09-05
Abstract: Dilute aqueous dispersions of polytetrafluorethylene are concentrated and stabilized by adding a surface-active agent to the dilute dispersion, flocculating the polymer by insolubilizing the surface agent, separating the flocculated polymer from the bulk of the aqueous phase and forming a concentrated dispersion by peptization of the polymer floc.  The surface agent may be ionic or non-ionic. Specified ionic agents are ammonium pentadecane-8 sulphonate, sodium dodecylbenzene sulphonate, C-cetylbetaine, stearyltrimethyl-ammonium bromide, polyammonium styrene/maleamate, saturated long chain alkyl sodium sulphate, dioctyl ester of sodium sulphosuccinate, or a polyglycol ether.  The non-ionic surface agents may be poly-N-vinyl caprolactam, polymethylvinyl ether, or polyethyl vinyl ether.  The flocculating of the polymer may be effected by physical, e.g. salts or a thermal change, or chemical methods such as change in pH. Suitable salts are ammonium carbonate, ammonium nitrite, sodium sulphate, potassium nitrate, trimethylamine hydrochloride, ammonium chloride, and ammonium nitrate.  The flocculated polymer may be separated by decanting, centrifuging or electroendosmosis.  The polymer floc p  can be peptized by addition of acids or alkalis, or, if flocculated by heat, the peptization may be effected by cooling, together with the addition of another surface-active agent. Dispersions of silica, titania, alumina, zirconia, ferric hydroxide, gold or silver may be mixed with the concentrated polytetraethylene dispersion prior to use.  The dispersions may be used for coating wire, fabric, wood, ceramics, carbon, impregnating metal structures and adhesives.  The dispersions are particularly useful for casting unsupported films and sheets of polytetrafluorethylene.

Abstract: 710,375. Electro-plating. WESTING- HOUSE ELECTRIC INTERNATIONAL CO. Oct. 26, 1951, No. 25078/51. Drawings to Specification. Class 41. A process of electro-plating on a base member a metal from the group consisting of copper, silver, zinc, cadmium, tin, gold and alloys in which these metals predominate, utilizes a plurality of cycles of periodically-reversed current, each cycle comprising a plating electrical current for at least 45 seconds to plate metal on the base members, and a de-plating electrical current for a period of time at least 30 per cent of the plating period, the average de-plating current density on the member being less than the average plating current density, and the coulombs delivered by the deplating current being between 30 per cent and 95 per cent of the coulombs delivered during the plating portion of the cycle, whereby a substantial portion of the previously-plated metal is de-plated, the plurality of cycles producing a smooth level deposit of plated metal. In the plating of copper an alkaline cyanide electrolyte containing from .0038 to .57 ozs. per gallon of zinc and from i to 10 ozs. per gallon of thiocyanate as addition agents may be used. The electrolyte and base member may have a relative movement of at least one foot a minute. Examples are given of aqueous cyanide baths for the plating of copper, brass, cadmium, silver and gold, and an acid bath for the plating of copper. Electrotypes and electroforming base members consisting of wax or resinous patterns plated or coated with powdered graphite or precipitated silver may be electroplated by the process claimed, and the electrodeposited metal stripped off. Plating in accordance with the invention may be followed by plating of nickel and chromium by direct current, without need for buffing. Specification 630,165 is referred to.

In a process and apparatus for shelling headless shrimps to produce fantail or butterfly shrimps - each of which has the tail (6th) segment attached to the body or meat - each shrimp, as shown in Figs. 4 and 5, is placed, with the ventral side of its 1st, 2nd, 3rd, 4th and 5th segments facing downwards, in the nip between two rotatably mounted metal rollers 30 and 31 having, for example, sand-blasted or rubber-covered peripheral surfaces. The tail (6th) segment carrying the tail, uropods and telson projects from one end of the nip, where the joint between the 5th and 6th segments is preferably supported by an anvil 35, so that downward pressure can be applied to the tail segment to dislocate said joint. Bars 36 and 37, Fig. 5, are then lowered on to the shrimp, and a ripping or slitting tool, preferably a rotating circular saw 39, is moved along the slot 38 between said bars to make a longitudinal dorsal cut through the shell of segments 1 to 5, thus facilitating their removal, and the removal of the sand-vein. The bars 36 and 37 are then raised and the rollers 30 and 31 are rotated in opposite senses, as by pinion gears, to draw the incised shell through the nip and away from the body or meat. The resulting fantail or butterfly shrimp is then removed from the rollers, e.g. by a jet of water.
