Title: Method of manufacturing a cryogenic conductor assembly on site
IPC: H01B12/14
Filed: 1971-09-03
Abstract: 1341718 Cryogenic connections COMPAGNIE GENERAL D'ELECTRICITE and L'AIR LIQUIDE LIQUIDE SOC ANON POUR L'ETUDE ET L'EXPLOITATION DES PROCEDES GEORGES CLAUDE 3 Sept 1971 [8 Sept 1970] 41297/71 Headings H1A and A4D A cryogenic connection, Fig. 2, comprises conductors 3; an inner fluid tight enclosure 1; a fluid tight heat shield 4 comprising cooling channels 22 in each face, a base portion 29 and a cover portion 19; and an outer fluid tight enclosure 5, pipes 17, 18 being provided to evacuate the space between the heat shield and the outer and inner enclosures respectively. Insulation material 6, e.g. an aluminabased powder is provided and cables 7, 9 support the inner enclosure and heat shield respectively. Polytetrafluoroethylene beads 8, 10 on the cables allow the triangular ducts to expand or contract longitudinally. Projections 20, 21 and ribs, e.g. 26, 27 are provided for strengthening purposes. Spot welding along the flattened margin portions 12, 14 of the enclosures secures the margins of each strip together and a continuous weld 28, 16 along and across the edges of each strip renders each enclosure fluid tight. The cooling liquid flowing through the connection may be as follows: liquid helium along the ducts 30; liquid nitrogen along ducts 22 and liquid helium along the ducts 2, said duct bounded by the surfaces of the conductors and the inner enclosure. The cable is manufactured in situ by forming machines which travel over the metal strips from which the components are made, laid out at the laying location. Firstly the outer enclosure is formed from a flat sheet steel strip into the configuration of Fig. 2 and the base portion of the heat shield is formed from an aluminium strip and suspended within the outer enslosure. The cooling channel in the base of the shield is formed by a "roll-bond" method, ink being applied between the metal layers to prevent welding in that area and then using air-pressure to expand the channel Figs. 11a, 11b, 11c, (not shown). Then the inner enclosure is formed out of a stainless steel strip, the conductors located therein and the enclosure closed and sealed. The top portion of the heat shield is then formed out of aluminium and the inner enclosure with the conductors is suspended therein. The heat shield top is assembled on its base, the insulation added. The vacuum connection pipe is inserted and the outer enclosure is then closed and sealed, Fig. 9.

Title: Method and apparatus for the treatment of organic waste material
IPC: F26B11/04
Filed: 1974-11-25
Abstract: 1493351 Drying sludge J C SOLLINGER 25 Nov 1974 [3 Sept 1973] 41344/73 Heading F4G  The invention relates to a method of and appatatus for drying and sterilizing wet sludge. The apparatus comprises a rotatable kiln 10 having a material inlet end 16 and a material outlet end 18 and along the length thereof a plurality of different agitating devices for controlling the drying of the material. High temperature non-combustible gas is passed through the kiln from the inlet end to the outlet end thereof. The length of the kiln is divided into a plurality of zones by the form of agitating device in each of the zones. The zones are a material reception zone, a transition zone, a granulating zone, a pelletizing zone and a winnowing zone. The agitating device in the reception zone comprises a plurality of linkage 24 formed by chains loosely looped in the zone, the chains when the kiln is rotated pulling the material dumped thereon when the linkages are at the lowest position of the drum in its rotation away from the sides of the kiln and also breaking it into pieces (Fig. 3, not shown). In the transition zone linkage also in the form of chains is used in combination with lifting vanes 34 which are radially extending at their outer ends and angled in the direction of the kiln rotation at their inner ends (Fig. 4, not shown), these vanes without chains passing through the granulating zone. Further vanes 34 telescopically cooperate with the first mentioned vanes 34 such that the length of the granulating zone may be varied (Figs. 5, 10, not shown). The pelletizing zone merely comprises the smooth inner surface of the kiln. The drying gas when it has reached the pelletizing zone has been cooled and the relative humidity is high. Thus the material in the pelletizing zone is moistened such that pelletization takes place. The kiln at the pelletizing zone may be provided with external cooling fins (Fig. 6, not shown). In the winnowing zone lifting vanes of L-shaped section are used, two sets thereof being telescopically cooperable such that the length of the zone may be varied (Fig. 8, not shown). The kiln is rotated at from 2-4 r.p.m. by drive rollers (Fig. 8, not shown). Alternatively the kiln may be mounted on rollers and driven through a gear train by a motor, the gear train meshing with a gear surrounding the kiln (Fig. 9, not shown).

Title: Improvements in and relating to fluid flow control devices
Inventor: BAINBRIDGE WILFRED NICHOLAS
IPC: F15B13/12
Filed: 1964-10-13
Abstract: 1,058,400. Valves. AUTOMOTIVE PRODUCTS CO. Ltd. Dec. 22, 1965 [Oct. 13, 1964], No. 41777/64. Heading F2V. [Also in Division G3] The connection of outlet ports 6, 7 to an inlet port 5 and return ports 8, 9 is effected by a piston valve 27 slidable in a ported sleeve 10 and an adjustable rod 52 with a central biconical land 61; the position of the valve 27 is determined by a nozzle flapper arrangement 45-47 influenced by an electrical input signal. Fluid entering the inlet 5 flows into an external groove 15 in the sleeve 10 from where it can enter outlet port 6 or 7 depending upon the movement of valve 27. The fluid also enters the annular grooves 31, 32 between valve lands 28-30 and flows via radial drillings 33, 34 where it is divided by the rod land 61 before admission to annular chambers 59, 60 between the rod 52 and valve 27; the fluid leaves each chamber 59, 60 by opposite-handed helical grooves 38, 39 to enter chambers 13, 14 connected to nozzles 45, 46, respectively. Movement of the flapper 47 from a neutral position increases the pressure in one chamber and decreases it in the opposite chamber, whereupon the valve 27 is displaced and the flow into each chamber is thereby altered by this displacement relative to the land 61 until the valve 27 reaches a position of equilibrium. The fluid discharge from the helical grooves 38, 39 causes rotation of the valve 27. In a modification, the rod 52 is dispensed with and the valve bore is intersected by a pair of inlets. The helical grooves are associated with chambers at the ends of the valve bore, whereby the effective length of the groove moving into the adjacent chamber is reduced to provide pressure compensation across the valve. The same effect may be realised by forming ports in the valve through which fluid is supplied to the grooves as shown in Fig. 1.

Abstract: 1,096,389. Smallware looms. J. D. RIORDAN and G. C. LIBBY. Oct. 5, 1965 [Feb. 18, 1965], No. 42264/65. Heading D1E. In a smallware loom weft is inserted by an eyed needle 14 and a knitted selvedge is formed on the left hand side of the fabric, a scalloped or looped selvedge being formed on the right hand side by timed rotation of a retainer 80 through which the weft passes. The rotation of the retainer is in forced relation to the reciprocation of the finger 14 so that some portion of the retainer 80 forms an arch over the finger 14 while it moves into and out of the shed. Thus, a length of weft W, extending from the fell around the retainer 80 forms a loop which is later released by clockwise rotation of the retainer. The retainer can be moved axially to vary the length of the loops thus produced.

Title: Preparation of film packs
IPC: G03B42/04
Filed: 1965-10-06
Abstract: 1,090,068. Evacuating film packs. EASTMAN KODAK CO. Oct. 6, 1965 [Oct. 13, 1964], No. 42341/65. Heading H5R. [Also in Division F1] A film pack, comprising a film and intensifying screen in face-to-face relationship within an air-tight flexible envelope, is prepared for exposure by perforating one wall of the envelope and evacuating air from the envelope through the perforation to cause ambient air pressure to collapse the envelope and force the film and screen into intimate contact. The evacuation of air may be maintained during the film's exposure. A selected portion of the envelope may be isolated from ambient air pressure before evacuation of the envelope. The entrained air within the envelope may cause the wall to expand and rupture during evacuation or the wall may be first ruptured, e.g. with a perforating member before evacuation. As shown in Fig. 3 an apparatus for evacuating the film pack after puncturing its envelope comprises a cup-shaped member the rim 31 of which engages with the film pack envelope and a perforating member 40 with its tip disposed behind the plane of the rim of the cup-shaped member and means to evacuate air from within the cup-shaped member, e.g. through connector 19. The perforating member, e.g. a knife blade or point, and the rim may be relatively movable so that the tip stands proud of the plane of the rim. The rim 31 may be resiliently connected to the body of the cup-shaped member. The perforating member may be within a recess, formed by member 52, so that the tip remains out of contact with the envelope wall until the latter is pulled inwardly by suction. The vacuum connector 19, sealed by rubber O-ring seal 22 and located by a set screw in groove 21, may connect via conduit bore 23 to transverse bore 24 in which there is a sliding vacuum valve 25 which connects to the cup-shaped member via hole 43. In other embodiments, not shown: (Fig. 7) the cup (60) is made of rubber and under a pressure applied to cross member (62), the member deflects casing needle (67) to perforate envelope (10); (Fig. 8) the entire cup (60<SP>1</SP>) is made of elastomeric material which may be deformed if necessary so that point (78) punctures the envelope; (Fig. 10) air is evacuated from the cup-shaped member by applying pressure to the cup thus deforming it and disengaging ridge (105) with the underside of the cup at point (106); air escapes past this ridge via channels (103) and (104) and the vacuum created retains the cup in its deformed position; (Fig. 11) the movement of the needle (67<SP>1</SP>) within the flexible cup (60a) in the direction of envelope (10) is restricted by a rigid disc (65<SP>1</SP>). In each of these last four embodiments, the cup is provided with a vent (71) to release the vacuum therein.
