Title: Improvements in or relating to totally cementitious pipes
IPC: F16L9/08
Filed: 1966-10-26
Abstract: 1,205,218. Cementitious pipes. JOHN DAVRON Ltd. 19 Oct., 1967 [26 Oct., 1966], No. 47960/66. Heading F2P. A method of manufacturing a totally cementitious pipe, which has an inner concrete surface and an outer layer of aluminous cement reinforced with a non-oxidizable fibrous material comprises the steps of forming separate lengths of concrete pipe, advancing the lengths of pipe, after setting, along a central mandrel and past a revolving head for winding non-oxidizable fibrous material around the pipe, applying the non-oxidizable material in a slurry of aluminous cement to the outer concrete surface of the lengths of pipe, and causing the aluminous cement reinforced by the fibrous material to adhere to the outer concrete surface. Aluminous cements are stated to include those having more than 25% by weight of alumina (Al 2 O 3 ), the reinforcement preferably being glass fibres or synthetic resin, or asbestos, fibres. As shown, a basic concrete pipe 2, mounted upon a mandrel 4, is axially advanced past a revolving head 6 which carries a number of reels 7 each of which delivers a fibreglass roving 8 to a guide 9 where it picks up a slurry of aluminous cement before being wound around the outer surface of the pipe 2. A ring 11, at each side of the head, passes over the corresponding ring of guides 9, and through a slurry tank 10, slurry being applied to the rovings 8 as they pass through the guides 9. In an alternative method a slurry of aluminous cement is applied to the outer surface of the pipe 2 and then the glassfibre rovings, not coated with slurry, are wound around the pipe 2. The outer layer is preferably between 1/16 and 1/4 inch thick.

Title: Devices for regulating the movement of a valve member of a valve  arrangement to control the supply of liquid to a liquid- filled strut of a vehicle suspension system
IPC: B60G17/056
Filed: 1971-10-08
Abstract: 1360990 Adjusting vehicle height AUTOMOTIVE PRODUCTS Ltd 8 Oct 1971 [8 Oct 1970] 47977/70 Heading B7D A levelling valve, which controls the supply of liquid to a liquid filled strut forming part of the suspension system of the vehicle, includes a regulating device which damps movement of the valve spool 20 away from its mean position but allows free movement of the spool 20 when returning to the mean position. The valve includes a body 10 which is mounted on the vehicle body and a spool 20 having a lug 31 which is connected to the axle by a flexible member (not shown). The spool 20 controls the flow of liquid between port 18, which is connected to a liquid filled strut of the suspension, and ports 17 and 19 which are connected to exhaust (e.g. a reservoir) and a liquid supply source respectively. The spool 20 has an extension 29 which is connected to a flexible diaphragm 35 which separates two liquid filled chambers 33, 34. The chambers 33, 34 are connected by a passage 44, the ends of the passage being closed by spring loaded plates 38, 40 when the spool 20 is in its mean position as shown. The passage 44 is also connected to a source of liquid supply 45. The plates 38, 40 have restricted orifices 42, 43 respectively. The arrangement is such that when the spool so moves away from its mean position, e.g. to the left, liquid flows from chamber 34 to chamber 33 via restricted orifice 43 so that the movement of the spool 20 is damped. When the spool 20 returns to its mean position liquid flows freely through the passage 44 because plate 38 is held open by projection 24 on the spool 20 and plate 40 is opened against the action of spring 41 by the pressure of liquid flowing through the passage 44. Thus the return movement of the spool 20 is undamped. Movement of the spool to the right operates the device in a similar manner. In a modification (not shown) the restricted orifices 42, 43 may be replaced by a single restricted orifice in the diaphragm 35.

Abstract: 1,199,536. Making tubular films. ETHYLENE-PLASTIQUE S.A. 11 Oct., 1968 [13 Oct., 1967; 1 Oct., 1968], No. 48415/68. Heading B5B. A device for cooling a tubular film or tubing of a synthetic organic thermoplastic polymeric material immediately after it has left the die through which it has been melt-extruded comprises a flexible slightly resilient porous stationary sleeve or tubular element consisting of a hydrophilic fabric supported only at its ends and which is located immediately downstream of the extrusion die and coaxial therewith and means for applying a cooling liquid to the flexible sleeve or tubular element. A similar sleeve coaxial with the first sleeve may be located downstream thereof in such a manner that any cooling liquid dripping from the first sleeve does not wet the second sleeve, means being provided for supplying a stream of a drying gas to the outer surface of the second sleeve. As shown in the drawing, a tubular film is melt extruded from the annular die of an extrusion head 10 and is cooled by passing through the sleeve 6 in contact with its inner surface. The sleeve may consist of a woven, non-woven or knitted fabric formed of hydrophilic fibres and water or other liquid coolant is supplied at a uniform rate to the outer surface of the sleeve and permeates it to form a thin film of liquid coolant in its inner surface. The space between the tubular film, the face of the extrusion head 10 and the sleeve 6 is either open to the atmosphere or connected by a pipe 11 to a pressure-regulating device. The two ends of the sleeve 6 are held in position by two rigid rings 1 and 2 which expand it slightly and between which it is stretched longitudinally. The upper part of the sleeve is surrounded by and in contact with a thick porous strip 4 of a hydrophilic material such as cotton felt on to which water is sprayed under pressure by a series of nozzles disposed at regular intervals along the inside of an annular manifold 5 coaxial with the extrusion axis. The lower ring 2 is attached to a tray 2 for receiving the liquid coolant flowing down the sleeve 6. A second similar sleeve 7 is disposed between rings 2 and 3 and currents of warm, dry air supplied to an annular chamber 9 surrounding the sleeve impinge on the sleeve and evaporate the water which has been wiped off the tubular film by the sleeve.

Title: Reproduction processes for cellular bodies
IPC: C12N15/873
Filed: 1974-11-11
Abstract: 1486468 Transplanting ova etc; fractionating sperm L L AUGSPURGER 11 Nov 1974 [23 Nov 1973] 48625/74 Heading C6F [Also in Divisions A1 and C5] A process for transplanting ova, or cellular bodies derived from ova, from a female hoofed mammal donor to a recipient foster female for maturation involves receiving ova from the donor, placing the recovered ova in tissue culture medium and storing the recovered ova for a period of time in such a way as to defer normal development of the ova, determining the time of ovulation in the recipient, removing one or more of the individual ova or cellular bodies derived from the stored ova in the culture medium, and transplanting the removed individual ova or cellular bodies to the recipient at a time such that the transplanted ova or bodies reach the blastocyst stage in the recipient at the time the recipient would normally implant a blastocyst had the recipient been fertilized. Male producing cellular bodies are separated from the female producing bodies before transplantation, whereby the recipient may receive only transplants of like sex. The genetic manipulation of the ova and cellular bodies is described in considerable detail. The cellular bodies may be cultured at a temperature between 30 and 38C in a culture medium containing glucose, saline solution, amino acids, vitamins and sodium pyruvate prior to their transplantation. Detailed formulations of suitable culture media are provided. A preferred medium includes lipoic acid, 1-glutamine and vitamin B 12 , and is buffered with HERPES buffer and sodium bicarbonate to pH 7-3-7.4. A gaseous cover consisting of 5 vol. per cent carbon dioxide and 95% air or oxygen should be provided. The ova may be kept under liquid nitrogen in a medium containing sodium pyruvate or sodium oxaloacetate. The spermatozoa are also pre-sexed prior to their use in the fertilizing by fractionation into the X and Y chromosome bearing spermatozoa. This may involve percolating the spermatozoa through cation exchange resins (leaving untrapped the spermatozoa capable of producing female offspring) or anion exchange resins (leaving male producing sperm untrapped). Preferred cation exchange materials are copolymers of carboxylic divinyl benzene, copolymers of methacrylic acid with divinyl benzene, and copolymers of maleic anhydride with styrene and divinyl benzene. Preferred anion exchange resins can be produced by nitration and subsequent reduction of styrene divinyl benzene copolymers. Particularly in the case of cattle sperm, due to the great difference in size the of X and Y spermatozoa. fractionation may be achieved in a counterstreaming centrifuge using speeds between 1000 and 1200 rpm and speeds below 1000 rpm for the recovery of the male and female producing fractions, respectively. The percolation or centrifugation is preferably conducted under a vacuum of 15 to 30 cm. Hg differential from the pressure at which the sperm were obtained. Fertilization of the matured oocytes, or "pseudo-fertilization" by sterile sperm or chemically, may be made in vitro.
