Abstract: 1420449 Medicinal iron preparations DEUTSCHE GOLD-UND SILBER-SCHEIDEANSTALT 31 July 1973 [31 July 1972] 36460/73 Heading ASB [Also in Division C3] Agents for the peroral treatment of acute anaemia and/or for the prophylactic treatment of anaemia in warm-blooded omnivores, e.g. piglets, comprise iron salts or complexes of polymers having an average degree of polymerisation of 3-600 and defined in terms of the molar percentages of 5 different types of unit, including essentially units containing carboxyl groups together with units containing aldehyde groups and/or units containing hydroxy groups. Units derived from dicarboxylic acids and units obtained by ring- opening polymerisation of aldehydes are optional. Suitable polymers are (a) a copolymer containing aldehyde groups and carboxyl groups and prepared by oxidising copolymerisation of acrylic acid and acrolein, and (b) a copolymer containing hydroxy and carboxyl groups prepared by subjecting polymer (a) to a Cannizzaro reaction with NaOH. In Example 1, an iron salt/complex of a (b)-type polymer is used per se in the treatment of piglets. The polymers may be used in admixture with other pharmaceutically active substances e.g. vitamins and antibiotics, excipients or other additives, e.g. antioxidants.

Title: Surface chlorination of polyolefine articles
Inventor: OSBORNE ALAN PAUL
IPC: C08J7/12
Filed: 1959-10-30
Abstract: The surface of an article of a polymer of an olefin of at least 3 carbon atoms, is subjected to the action of a chlorine-liberating compound for a time sufficient to cause chlorination and the absorption of uncombined chlorine at the surface. The treatment may be effected in water \sB an organic solvent and is preferably on an abraded surface of the polyolefin. The chlorine liberating compounds specified are dichlorodimethyl hydantoin, di- and tri-chloro-derivatives of isocyanuric acid and alkali and alkaline earth metal hypochlorites, and the polyolefin may be isotactic polypropylene or polybutylene.  The treated polyolefins may easily be dyed, or laminates may be obtained by applying the treated article, e.g. sheet, to an elastomer which on heating becomes vulcanized and bonded to the polyolefin. Applications are conveyer belting, tyres, hose and flexible containers.

Abstract: 1510517 Pipe couplings: valves SHIPOWNERS REFRIGERATED CARGO RESEARCH ASSOCIATION 9 Sept 1976 [9 Sept 1975] 37147/75 Headings F2G F2V [Also in division F1] A coupling for connecting an air conditioning duct with an aperture in the wall of a container (not shown) comprises a first end 1 for connection to the duct and a second end 3 which is displaceable away from the member 1 and includes an annular seal 5 for sealing around the container aperture when so displaced, the ends 1, 3 being interconnected by an annular body 25 connected to at each of its ends to a rolling diaphragm 13 held in peripheral U-section annuli on each of the ends 1, 3, the diaphragms defining inflatable spaces 15 which when supplied with fluid under pressure cause displacement of the member 3 away from the member 1 to engage the seal with the container wall. Inflation tubes 23 are provided for this purpose and the two spaces 15 may be separately supplied if desired, but it is preferred that they are interconnected by passageways 27 through the annular body 25. Only one rolling diaphragm 13 may be provided if desired. The ends 1, 3 are also connected by a pair of scissor hinges 29 comprising plates 31, 33 pivoted about vertical axes to allow a degree of horizontal movement of the end 3 for alignment with the container aperture. A small degree of vertical adjustment is also allowed. Springs 43 provided for extraction of the end 3 on release of the fluid pressure in the spaces 15. The ends 1, 3 are preferably of glass-filled polyester and the annular body 25 of polyurethane foam having a fluid impervious skin to provide the necessary insulation. A butterfly valve 7 is provided in the end 3 which is pivotally mounted on a shaft 47 and connected by a link 47 and pins 51 engaging in a slider track 45 secured to the valve 7 for automatic opening of the valve as the ends 1, 3 move apart, as is disclosed in Specification 1,318,421. However, in the present invention a separate actuating device (Fig. 4) is provided to open or close the valve 7 when desired. In this device there is provided a cylinder 65 in which a piston 73 reciprocates under the action of fluid under pressure applied to an inlet 71, a rolling diaphragm 67 sealing between the piston and cylinder, and a spring 75 providing for return of the piston when the pressure is released. Rotation of the piston is prevented by engagement of axial splines on a projection 81 of the piston 73 with axial splines 77 in a sleeve 76 fixed to the cylinder 65. Helical splines 83 are provided on the inner surface of the projection 81 to engage with similar splines on a housing 85 rotatably mounted in the cylinder 65, so that movement of the piston 78 will rotate a shaft 89 fast with the housing 85, the shaft 89 opening the valve 7. The parts of the actuating device are preferably of acetal resin to reduce friction.

Title: Improvements in or relating to steam generating and superheating installations
IPC: F22G3/00
Filed: 1934-12-31
Abstract: 451,279. Steam superheaters. SUPERHEATER CO., Ltd., and WOOD, J. E., Bush House, Aldwych, London. Dec. 31, 1934, No. 37356. [Class 123 (iii)] To protect a superheater from overheating during pressure raising, steam or water at super-boiler pressure is supplied to a flow inducing apparatus between the superheater outlet and the boiler to induce a flow of steam through the superheater which is then returned to the boiler. An installation comprising two boiler units A, B, each with drum 1 and superheater 2, has an energy converting apparatus 11 connected between the saturated steam range 8 and a return line 20 to the boiler drum, with a pipe 13 leading from a superheated steam pipe 9. Apparatus 11 comprises a converging nozzle 16, a diverging tube 19 with flared inlet and a surrounding chamber 12. With pressure being raised in unit A and unit B on load, valves 7, 10 of unit A are closed and steam from unit B is delivered by pipe 17 to nozzle 16 and thence into tube 19, inducing a flow of steam through the superheater and chamber 12, the steam pressure being raised in the divergent tube above that in drum 1 into which it is delivered. In another arrangement applicable to single unit installations, the steam pipe between superheater and apparatus 11 is branched and a steam pump in the branch pipe withdraws e.g. 10 per cent of the steam for supplying nozzle 16. In a further modification, a pump withdraws water from drum 1 or the feed line for use as the high pressure fluid in apparatus 11. By automatic regulation of valve 18 in pipe 17 or of the pumps in the modified arrangements, the difference between boiler pressure and that at the entrance to apparatus 11 may be controlled to produce the required steam flow through the superheater over the range of boiler pressures from atmospheric to main range.

A variable-speed regulator for a prime mover comprises a centrifugal governor having flyweights 2 loaded by springs 5, a control rod 9 movable axially by the outward movement of the flyweights, a screwed member 10 positioned a predetermined distance from the control rod so as to be contacted and moved thereby after outward movement of the flyweights a predetermined distance, resilient means 15 opposing movement of the member 10, and means for transmitting such movement of the latter member to the distributing mechanism of the prime mover. The flyweights are connected by pivots 3 to a drive shaft 1 and loaded by the springs 5 which are retained on the shaft by threaded spindles 7 and nuts 6, movement of the weights being transmitted to the rod 9 by a pivot 8. The member 10 is provided at one end with a threaded portion engaging a bush 11 pivoted in a forked lever 12 which is secured to a shaft 16 connected through linkage to the fuel supply of the prime mover; one of the pivot pins of the bush 11 extends inwardly into engagement with the threads on the member 10.

In an alternative arrangement, the bush 18 may project into the governor casing for rotation by a nut. In the modification shown in Fig. 5, the member 10 is replaced by a lever 28 having a boss secured eccentrically to a shaft 30 connected by linkage with the engine throttle, the centre position of the shaft 30 being adjustable by a lever 32 in order to vary the distance between the lever 28 and control rod 9; alternatively, the eccentric arrangement for adjusting the lever 28 may be replaced by a link of adjustable length in the linkage between the lever 28 and throttle. The position of the linkage at rest is set by a stop 35, against which the linkage is urged by a spring 34. The governor 2, 5 may be of the kind described in Specifications 691,011 and 798,730.
