Filed: 1972-07-10
Abstract: 1385824 Pipe couplings DEMPCO Inc 10 July 1972 [9 July 1971] 32231/72 Heading F2G In a fluid line coupler device having a housing 24 and a piston body 42, an annular piston 45 is actuated by fluid pressure to open the selfsealing valves of both the piston body 42 and a co-operating coupler nipple 26. The fluid is supplied through duct 51, which is covered by an elastic ring 50, acting as a non-return valve. Space 56 is continuously bled via valve (67, Fig. 1, not shown) to reservoir (R), so that if valve (12) is closed the pressure in space 56 drops and valves 34 and 58 close. This enables the coupler fastening to be released safely, while the nipple 26 remains under pressure. In a modification, employing two couplers, valve (67) is closed, ring 50 is omitted and duct 51 is made into a very small bleed duct in the return (low pressure) coupler, thus achieving the same result. A pull on the coupler device is transmitted by members 70, 71, to effect release of the fastening.

Title: New polysaccharide and process for preparing same
IPC: A61K31/715
Filed: 1961-09-11
Abstract: A tumour-inhibiting polysaccharide, viscic acid, or salts thereof is extracted from plant material of viscum album or Loranthus species, especially L. europeus L.  The novel polysaccharide has a pK acid value of 3,9 (C=1,1x10-2 equivalents/l) and a specific rotation of [a ]25= -26,7 DEG  \sB1 DEG . The molecule is composed of galactose, arabinose, rhamnose and a uronic acid, possibly glucuronic acid.  The ultra-violet spectrum contains no absorption bands, while the infra red spectrum shows maxima (in mm ) at 2,95-3,00; 5,74; 6,08, and a shoulder at 7,2 with a maximum at 8,00-8,05.  Viscic acid is isolated by extracting the plants with water, or by expressing the juice, followed by dialysis of extract or juice.  The undialysable portion, is advantageously concentrated or freeze-dried to yield a plant extract enriched in viscic acid or salts thereof.  Pure, free viscic acid or salts thereof may be isolated by, e.g. fractional precipitation with water-miscible organic solvents, particularly ethanol, optionally in presence of absorbents or strong electrolytes; by electrophoresis; or by precipitating contaminants with a quaternary ammonium compound, e.g. cetyl trimethylammonium chloride, followed by dialysis and freeze-drying.  Ammoniumsalts may also be used to precipitate viscic acid in presence of a borate buffer of pH 10.  Free viscic acid may be obtained from salts by, e.g. cation exchange, or dialysis against dilute acid.  Viscic acid or salts thereof may be used for treatment of cancer diseases, e.g. in conjunction with pharmaceutical organic or inorganic vehicles.  The pharmaceutical preparation may be in the form of dry ampoules which may contain preserving, stabilizing, wetting or emulsifying agents.ALSO:Pharmaceutical preparations contain viscic acid, a tumour-inhibiting polysaccharide isolated from Viscum album (mistletoe) or Loranthus species, e.g. Loranthus europeus L. (Group IV (a)).  The preparations may comprise viscic acid and/or a salt thereof in admixture of conjunction with an inorganic or organic carrier suitable for parenteral administration.  The preparations may be in the form of dry ampoules and may be sterilized and may contain preserving, stabilizing, wetting or emulsifying agents, salts for regulating osmotic pressure, buffers or other therapeutically active substances.  The active substance may be recovered from the non-dialysable portion of an aqueous extract or the expressed juice of plants of the Viscum Album (mistletoe) or Loranthus species.

Title: Foam pump system
IPC: A62C25/00
Filed: 1963-08-19
Abstract: 1,049,737. Rotary pumps. CHEMETRON CORPORATION. Aug. 19, 1963 [Aug. 27, 1962], No. 32725/63. Heading F1F. A rotary pump in a foam pumping system for extinguishing fires, comprises a cylindrical casing 23, Fig. 3, eccentrically mounting a rotor 30 having a central boss 34 and spokes 35 forming therebetween hollow spaces 36 to reduce rotor weight and slotted to slidably receive vanes 37a-f, angled as shown (or radial). The casing is surmounted by a manifold 28 having inlet and outlet portions 28a, 28b connected respectively to adjacent pump inlet and outlet passages 25, 26 separated by a wall 27. The inlet portion 28a is connected through a pipe 16, Fig. 1, vented to atmosphere through a predetermined restricted orifice 18 to a valve 15 which proportions the desired amount of water and foam stabilizer from tanks 11, 12 respectively and the outlet portion 28b is connected through a pipe 21 to nozzles 20. In operation, on rotation of the rotor 30 in the direction of the arrow, vacuum is initially created behind the vanes and this vacuum through an operative connection between the pump and the valve 15, opens the valve to supply a water and foam mixture to the pump. A horn-shaped port 51, Fig. 4 (not shown) in one end face of the casing 23 is positioned to suck in air during the intake cycle of the water and foam, and this air is compressed during the discharge cycle of the pump. This is stated to improve the efficiency of the pump, the air requiring less energy to compress than the liquid being introduced when the vanes are in their fully extended position. The air admitted through the orifice 18 in controlled amounts adjusts the initial vacuum in the intake cycle and hence the amount of opening of the valve 15 and the amount of liquid supplied to the pump and consequently the proportion of liquid to air which is varied depending upon the type of fire to be tackled. Instead of air being admitted through the port 51, carbon dioxide, nitrogen, hydrogen or other gases may be used. The pump is driven through reduction gearing. The direction of rotation of the rotor may be reversed, in the case of a rotor with angled vanes this will necessitate the end-to-end reversal of the rotor. The pump may be truck mounted on feet 22.
