Title: Method and apparatus for swivelling a spray nozzle about a swivelling axis
IPC: E21D11/10
Filed: 1977-05-31
Abstract: The apparatus serves for pivoting to and fro a spray nozzle (6) which is connected to a spray hose (7). With the aid of a pivoting motor (9), the holder for supporting the spray nozzle (6) can be pivoted to and fro about a pivot axis (10). The pivoting motor (9) is connected to working lines (21, 22) in each of which is arranged an overpressure compensation valve (29, 30). These overpressure compensation valves (29, 30) have the purpose of preventing an acceleration of the pivoting movement under the weight of the spray hose (7). As a result of this, an automatic control of the pivoting speed is obtained. A pivot control unit is further provided which optionally serves for automatically or manually controlled pivoting of the spray nozzle (6). With this apparatus, the desired pivoting movement of the spray nozzle (6) can be achieved simply and effectively. A uniform coating with the medium applied is thus obtained. <IMAGE>

Title: Process for improving the stability to heat of shaped polyvinyl chloride and the like
IPC: C08F8/20
Filed: 1938-08-04
Abstract: 517,689. Artificial filaments, films etc.; polyvinyl compounds. GROVES, W. W. (I.G. Farbenindustrie Akt.- Ges.). Aug. 4, 1938, No. 23065. [Classes 2 (ii) and 2 (iii)] The stability to heat of shaped structures of polyvinyl chloride, after-chlorinated polyvinyl chloride, or mixed polymerizates containing polyvinyl chloride is improved by subjecting them to the action of a gaseous halogen or of a solution of halogen in water or another indifferent solvent. Fibres, threads, fabrics, films, bands, hosepipes, rods, or other articles may be treated. Threads of polyvinyl chloride which begin to soften and shrink at 70C. are subjected to treatment with a warm dilute aqueous solution of bromine. The treated threads shrink at 85-90C. Polyvinyl chloride threads are treated with moist chlorine gas. Threads of a mixed polymerizate from vinyl chloride and vinyl acetate or fabrics made of such threads are treated with chlorine gas. After-chlorinated polyvinyl chloride is spun to form threads and. these are treated with bromine water, or moist chlorine gas. Specification 401,200 is referred to.

Title: Improvements in vacuum manometers
IPC: G01L21/04
Filed: 1926-09-20
Abstract: 264,759. Weintraub, E. Sept. 20, 1926. Vacuum gauges.-Comprises a vacuum manometer of the McLeod type in which the level of mercury in the barometric tube is limited by an overflow to a surrounding vessel and thus made independent of atmospheric pressure. The bulb E is in communication with the space in which the pressure is to be measured through passages L, H, B, the valve J being at the bottom of the chamber or passage L. Between the points C, B an overflow passage G is provided, preferably at the same height as the closure of the tube D. When the mercury is raised by raising the cup F, the volume of gas in the bulb E is isolated and compressed into the capillary tube D, the mercury also closing the valve J and rising in the passage K until it overflows at the orifice G, the overflow collecting in the chamber H. The mercury level is therefore the same in this branch for all readings, and the level in the tube D is the only reading to be made. The tube D can therefore be graduated in terms of the pressure to be measured, and the instrument, with the exception of the tube D, may be made entirely of steel, the tube D being made of a thick-walled capillary tube.

Abstract: 1416204 Anti-skid braking systems WABCO WESTINGHOUSE GmbH 17 May 1973 [18 May 1972] 23621/73 Heading F2F In an anti-skid braking system, at least one brake cylinder 5, has a pressure chamber 6 controlled by a regulating valve assembly 1, and a return chamber 58 opposing the pressure chamber and provided with a connection to the pressure chamber via the assembly which is effective during brake release allowing air to pass via the return chamber to atmosphere to reduce noise. Air, from a source 4, is controlled by an actuating valve 9, and, during braking, passes through a passage 25 a restriction 28, a diaphragm valve 21, which is open, a variable restrictor 30, 35, operated by a piston 31, and a line 8 to the pressure chamber 6. When a skid signal is transmitted, a control unit 14 operates a solenoid valve 12 opening communication from the passage 25 to the other side of the diaphragm 21 to close the valve. Simultaneously, a diaphragm valve 51, controlling communication between the pressure chamber 6 and the return chamber 58, which is held closed by air pressure via an inlet 53 communicating with a line 7, is opened by a solenoid valve 13 closing such communication. The size of a passage 56 in the body of the valve 51 is chosen along with a restricted port 61 in the return chamber to atmosphere to optimize noise reduction due to air exhausting. The pressure chambers of a plurality of brake cylinders may be connected to one or more return chambers via such a valve 51.

Title: Process for extraction and separation of metals using liquid cation exchangers

Filed: 1974-05-29
Abstract: 1474944 Recovering metal values G THORSEN 29 May 1974 23792/74 Heading C1A A process for the extraction and separation of metals from a solid raw material, e.g. oxidic ores or alloy scrap, comprised (1) leaching the solid with an organic phase consisting of a solution of carboxylic acid(s) and/or alkyl phosphoric acid(s); (2) separating residual solids from the organic phase containing organometallic complexes; (3) contacting the organic phase with an aqueous metal salt solution in liquidliquid exchange whereby a less basic metal is extracted from the aqueous phase into the organic phase and complexed therein, while a more basic metal passes from the organic phase into the aqueous salt solution; (4) contacting the exchanged organic phase with a mineral acid or gas to strip the less basic metal theregrom. The aqueous metal salt solution may be obtained by (a) leaching the solid residue from step (1) with mineral acid, or (b) leaching the initial raw material with mineral acid, or (c) utilizing an outside source, e.g. waste mine water or pickle liquor. In one embodiment Fe-containing calcined ZnS ore is leached to provide an organo-Zn complex solution which is thereafter used to remove (by liquid-liquid exchange) iron from an aqueous iron and zinc sulphate solution, the iron then being stripped from the resulting organo-Fe complex solution. In another embodiment in which Cu, Zn and Fe are recovered as sulphates from mine water solid CaO is added to a recycled ZnSO 4  solution to form a starting material which is leached with the organic phase to provide an organo- Zn complex solution. This is exchanged with the mine water in stages to produce separate organo-Fe and organo-Cu complex solutions which are then stripped with H 2 SO 4 .
