Patent GB-1302127-A (GB)
IPC: B67C3/26
Filed: 1970-02-02
Abstract: 1302127 Container filling device A-T-O Inc 2 Feb 1970 4886/70 Heading B8T In a counterpressure filling device in which the liquid is given a component of centrifugal motion so that it flows down the inner surface of the container, a gas supply tube 70 slidably located in an apertured sleeve 24 mounted in a beverage reservoir 12 has a liquid valve assembly 32 comprising a helically vaned conical member 68, the lower end of which has a resilient closure member 76 seated on the frustoconical wall (94), Fig. 6 (not shown), of a ferromagnetic check valve member 34. This conical wall sits on a valve seat 38. When gas valve 116 is opened to apply counter pressure to the container 22 via the supply tube 70 and a vent tube 80, the bottle pressure acting on the bottom surface of closure member 76 together with the force exerted by a spring 84 causes the member 76 to rise, the check valve member 34 following this movement as it is attracted upwardly by magnets 110. Liquid flowing through the sleeve 24 and round the vanes impinges on the check valve member to force it downwardly, and flows in a spiral path down the sides of the container 22, whilst counterpressure gas flows back through the vent tube 80 and supply tube 70. Gas flow ceases when vent tube aperture (82), Fig. 4 (not shown), is covered, this stopping liquid flow so that check valve 34 is again urged upwardly against closure member 76 to form a liquid and gas tight seal. A snift valve (50) is provided. Constrictions below the vanes increase the velocity of liquid flow.

Title: Combined static and fluid selas
IPC: F16J15/34
Filed: 1971-01-22
Abstract: 1309865 End face seals ENGLISH ELECTRIC CO Ltd 4 Jan 1972 [22 Jan 1971] 2974/71 Heading F2B A seal for the shaft 1 of a gas-cooled alternator, gas circulator or compressor comprises first and second sealing surfaces 25, 13 each cooperating with a common sealing surface 7 of the shaft, means, such as spring bellows 33 and the pressure of the working gas, for urging the second sealing surface towards engagement with the shaft sealing surface, and a pressure fluid system (oil) which is operable when the shaft is rotating to provide a pressure fluid layer 32 between the first sealing surface and the shaft sealing surface while simultaneously preventing engagement of the second sealing surface and which can be made inoperative when the shaft is stationary to destroy the fluid layer and allow the second sealing surface to make a static seal. The second sealing surface is provided by seal ring 13 formed of P.T.F.E., aluminium, silver or synthetic rubber mounted in an annular piston 9, 10, 11. The bellows 33 for urging the piston out of engagement is supported on a ring 34 secured to the housing. The first sealing surface 25 is provided on a seal ring unit 23, 24 sealed to the piston by inner and outer bellows 20, 21. The pressure fluid is supplied through passages 3 and slidable connecting tubes 18 to the space 26 between the bellows where it acts on a surface 40 of the piston to disengage it from the shaft sealing surface 7 and passes through passages 29, 30, 31 to form the fluid layer 32. This escapes radially outwards to a chamber 5 for feed back to the supply system and radially inwards for feed back through a primary drain 35 via holes 35A and space 4, a secondary drain 36 being provided for returning oil which has escaped radially inwards into the clearance gap between the shaft 1 and a gland surface 39. The latter is grooved helically to provide a pumping effect. Upon shut down, the oil pres-  sure is cut off after the shaft 1 has come to rest so that the fluid layer 32 is destroyed and the piston 9, 10, 11 moves under the action of the spring bellows 33 and gas force to engage the seal ring 13 on the shaft sealing surface 7. In a second embodiment, Fig. 2 (not shown), the spring pressure on the annular piston (55) is provided by coil springs (58) instead of a bellows and the seals between the piston and housing and between the piston and the seal ring unit 61, 66 are provided by 0-rings instead of the bellows.

Abstract: 1312622 Air cushion vehicles; elevated railways TRACKED HOVERCRAFT Ltd 10 April 1970 1695/69 Headings B7K and B7L A gas cushion vehicle designed for operation along a concrete track 2 has guide and support gas cushion pads 5, 6 mounted on a vehicle body 10, supplied with air through flexible ducts 13 which transmit part of the vehicle load to the pads, and having resilient connections 20, 25 which provide an increasing resistance to movement as the pads approach the vehicle body 10. The pads comprise a base 16 and outer member 17 with an air cushion supplied and contained by a fluid curtain from nozzle 12. The pads are connected to the body by linkages 20, 32 each composed of two links 21, 22 or 33, 34 pivotally connected together and to the base 16 and body 10 respectively. Linkages 20 are arranged at right angles to linkages 32 so that movement of the pad relative to the vehicle body is prevented. Torsion bars 25 are connected at one end to each link 22 at its pivotal connection 24 to the body 10, the other end of each bar 25 being rigidly attached to the body so that movement of pad 6 towards body 10 causes the bar 25 to twist and increasingly to resist the movement. In order to provide resistance to roll, linkages 32 on adjacent support pads 6 are connected together by torsion bars 30. The vehicle is propelled by two linear induction motors having stators 7 attached to the vehicle and a reaction rail 8 on the track. In a modification, Fig. 8 (not shown), provision may be made for each torsion bar 25 to be rotated by a ram (54) and lever (52) so as to retract the pads in an emergency or when the vehicle is stationary so that it can rest on skids or wheels. In another embodiment, Fig. 7 (not shown), the resilient connections may be air springs (41) which may be individually controllable in accordance with displacement measuring devices (42) to level the vehicle.

Title: Rangefinders
IPC: G01S17/18
Filed: 1971-11-29
Abstract: 1325069 Laser radar BRITISH AIRCRAFT CORP 29 Nov 1971 [10 Dec 1970] 58747/70 Heading H4D A pulsed laser radar is provided with a walking gate and an integrating circuit (R1, C1) receiving any gated echo signals and stopping the movement of the gate when the output of the integrating circuit reaches a predetermined threshold. Such integration is said to increase the signal to noise ratio of the system. A pulse generator 10 provides pulses for the laser 12 (gallium arsenide diode) and also causes the commencement of a fast ramp signal from generator 16 at the instance of transmission of the laser pulse. The amplitude of each fast ramp signal is compared at 18 with that of descending slow ramp signal from generator 20. The "equality" pulse from 18 "walks" through each laser pulse period starting from a maximum range and decreasing to minimum set by limit 30, the walking pulse gate from generation 22 causes the closing of gate switch S1 and the opening of earthing switch S2. This results in that any gated echo signal is based on the D.C. level of the earth. When the gate pulse starts to walk through an echo signal, the predetermined threshold becomes excedeed and switch 83 is operated to remove the positive operating voltage from generator 20. A negative voltage, via high resistance R2 now controls generator 20 and the slow ramp signal very slowly increases to cause the gate pulse to walking back through the echo signal until it is lost and the threshold is no longer exceeded. Switch S3 then reconnects the positive voltage. The gate pulse then walks back and forth through the echo signal. The minimum range signal produced by 30 causes switch 54 to connect the negative voltage to be applied to the generator 20 via a very low resistance R4 such that the slow ramp rapidly "flies-back" to its maximum value.

Abstract: PCT No. PCT/GB92/01511 Sec. 371 Date Jun. 22, 1994 Sec. 102(e) Date Jun. 22, 1994 PCT Filed Aug. 14, 1992 PCT Pub. No. WO93/03710 PCT Pub. Date Mar. 4, 1993.Contaminating protein is removed from a water soluble gum such as alginate by dialyzing a solution of the gum against a solution of a disulphide bond reducing agent. Purifying the gum by removing antigenic protein improves biocompatability of the gum for making biocompatible capsules containing cells such as mammalian cells. The reducing agent is preferably dithiothreitol, dithioerythritol or 2-mercaptoethanol. Dialyzing is preferably carried out for more than 1 hour and more preferably twice, each time for 2 hours. Cells are encapsulated by forming a suspension of cells in an aqueous solution of the gum, forming droplets from the suspension, gelling the droplets with a multivalent cation, contacting the gelled droplets with a polymer containing cationic groups, such as poly-1-lysine chloride, that cross-link with anionic groups of the gum to form a semi-permeable membrane around the droplets, and coating the membrane with a layer of the dialyzed gum. Islets of Langerhans cells can be encapsulated for implanting to produce insulin. In addition to encapsulating cells, the purified gum can be used in making dressings, swabs, sutures, stitches, controlled or sustained release devices and artificial vascular grafts that come in contact with body fluids such as blood.

Abstract: Important intermediates for preparing cephalosporin antibiotics, 7-amino-cephalosporanic acid (7-ACA) and 7-aminodeacetylcephalosporanic acid (7-ADAC), are prepared by a novel bioprocess in which a transformed Penicillium chrysogenum strain is cultured in the presence of an adipate feedstock to produce adipoyl-6-APA (6-amino penicillanic acid); followed by the in situ expression of the following genes with which the P. chrysogenum has been transformed:   1) an expandase gene, e.g., from Cephalosporium acremonium, whose expression product converts the adipoyl-6-APA by ring expansion to adipoyl-7-ADCA; 2) an hydroxylase gene whose expression product converts the 3-methyl side chain of adipoyl-7-ADCA to 3-hydroxymethyl, to give the first product, adipoyl-7-aminodeacetylcephalosporanic acid (7-ADAC); and 3) an acetyltransferase gene whose expression product converts the 3-hydroxymethyl side chain to the 3-acetyloxymethyl side chain of adipoyl-7-ACA. The final product, 7-ACA, is then prepared by cleavage of the adipoyl side chain using an adipoyl acylase. The entire synthesis, accordingly, is carried out using bioprocesses, and is efficient and economical.
