Title: Dual temperature exchange systems
IPC: C01B4/00
Filed: 1972-03-22
Abstract: 1403562 Exchange process DEUTERIUM CORP 22 March 1972 [22 March 1971] 52480/74 Divided out of 1403561 Heading C1A A material exchange system for exchange of two materials between two fluid phases, e.g. for the concentration of deuterium in sea water, comprises a first enrichment section having at least two pairs of hot and cold towers having separate feed supplies for one of said fluid phases and separate outputs connected in parallel to a pair of hot and cold towers of an intermediate enrichment section, the output of which section is passed to a final enrichment section. The tower pairs have means for passing the fluid substances sequentially therethrough in countercurrent and with recycling and (a) one of the tower pairs of the first enrichment section has sufficient exchange elements to ensure that when the volume of enriched fluid withdrawn is reduced (as by bringing in the second tower pair) the reduced quantity of fluid carries at increased concentration the same quantity of material and (b) the final enrichment section has sufficient capacity to produce the desired concentration of product when said quantity is not thus reduced. Where the fluid passed to the intermediate enrichment stage is in gas phase, a heat exchanger may be provided in the first stage to cool the recirculating portion and condense vapours of the other (liquid) phase contained therein. Specification 1,403,562 is referred to.

Title: Combined over-and-under pressure relief valves
IPC: F15B21/04
Filed: 1972-11-16
Abstract: 1393450 Valves DANFOSS AS 16 Nov 1972 [16 Nov 1971] 53004/72 Heading F2V An over- and under-pressure relief valve for use with double acting pistons, comprises a housing 12 formed with ducts 6 and 7 for high pressure fluid and a duct 13 for low pressure fluid; a spring 22 urging two closure members 21 against seats 20; and two closure members 29 co-operating with seats 25. When high pressure fluid from one side of the double acting piston enters the valve housing through duct 7, the right-hand member 21 is lifted off its seat so that the fluid communicates with a drain through duct 13. Meanwhile the associated closure member 29 is urged against its seat 25, whilst the closure member 29 in the left-hand member 21 permits the flow of low-pressure fluid from the duct 13 to the opposite side of the double acting piston. The situation is reversed when highpressure fluid is supplied through duct 6. Passages 31 are prevented from being closed by the members 29 by giving the passage a square cross-section, or by providing suitable projections or a spring ring (32), Fig. 4, not shown, formed with projections.

Abstract: 1506860 Disc brakes AUTOMOTIVE PRODUCTS Ltd 28 Nov 1975 [12 Dec 1974] 53768/74 Heading F2E A caliper 24 of a disc brake is supported for sliding movement on a crescent-shaped fixed support member 16 by means of keys 22, each of which is accommodated in a respective slot 21 in the support member 16 and in a respective slot 23 in the caliper 24 and each of which has a head 25. The caliper incorporates a fluid pressure cylinder 29 in which a piston (31) is slidable to actuate a brake pad 35, an oppositely disposed brake pad 36 being actuable through the caliper 24 by means of a limb 39 thereof secured to pad 36; as pad 36 wears the caliper 24 repositions itself to move limb 39 nearer to the disc 15, and the ends of the slots 23 remote from limb 39 move out of contact with the respective key 22 and the lengths of the slots 23 projecting beyond the heads 25 increases.

Title: Improvements in or relating to Creels for Thread Packages.
Inventor: BARRACLOUGH ERNEST CHARLES
IPC: D01H1/18
Filed: 1967-11-29
Abstract: 1,192,210. Creels of thread packages. E. C. BARRACLOUGH. 27 Nov., 1968 [29 Nov., 1967], No. 54270/67. Heading D1J. A creel for thread packages has a framework 10 on which a block 12 of a package mounting is fixed. A turntable 18 rests on block 12 and is rotatable about post 14. Pegs 20 (22, 24 not shown) provide packing positions for thread packages 16 which have their longitudinal axis parallel. A guide eye 30 for receiving thread from packages 16 projects from a bracket 32 swingably mounted on post 14 and resting on a fixed collar 26. Bracket 32 is braked by the pressure of the adjustably fixed collar 28 on compression spring 34. Due to this braking force guide eye 30 remains stationary while thread is unwound from one package 16 but will move round 14 when the tension in the thread is increased due to a change over to the next package. Turntable 18 can be rotated manually to bring any one of the package positions to a loading and unloading position. A similar mounting may be provided above this first one, differing in that a tube 38 extends vertically between its package positions so that thread from package 16 may be threaded through tube 38. Alternatively the packages could be arranged in a row with a guide eye slidable on a bar above them. Yet again the turntables 18 may be fixed to the supports 14 and 38 and rotate on bearings 12 and 40 which are fixed to frame members 10 and 36 respectively. Thus guide eyes 30, 44 revolve with each package station without any delay so that thread breakages are avoided.

The source and detectors are moved in the X direction relative to the body 2 and can be moved relative to each other in the Y direction by means of telescoping members 11, 14 and 12, 15 so that the point of interest 9 can be scanned over the whole cross-section of the body, and by providing for movement perpendicular to the figure the entire body can be investigated. The scintillators 21 can be divided into segments or a lead disc with a radial slot can be rotated in front of them to investigate variations in scattering in different directions corresponding to various # values. Data representing the direction and energy of the scattered radiation is processed in a computer to determine the location of scattering centres in the body.

Abstract: 1,190,379. Rotational casting of thermoplastic powders. AQUITAINE-FISONS Ltd. 7 Dec., 1967 [8 Dec., 1966], No. 54964/66. Heading B5A. Hollow mouldings of a thermoplastic polymeric material, which are internally lined with a second polymeric material of higher melting point, are moulded by charging both materials to a mould which is heated to a temperature, intermediate the respective melting points, as the mould is rotated about one or more axes so that a reservoir of unsintered particles remain at the lowest point of the mould as an outer continuous skin of the low melting point thermoplastic material is formed by sintering, the mould then being heated to a temperature above the higher melting point to complete the sintering of the particles to form the internal lining. The mould is heated by a hot liquid spray, e.g. of molten salts, or may be jacketed and oil heated. The mould may be heated to above the higher melting point before all the first material particles are sintered whereby bonding between the layers of material is enhanced. The thermoplastic polymeric materials may comprise combinations of a low density polyethylene with polyaminoundecanoamide, polyvinyl chloride with polyvinyl alcohol or a polyamide or a polyethylene. Other materials which may be used are polypropylene, polycaprolactam or cellulose acetate butyrate.

The phosphate content of sludge being recycled in an activated sludge process is reduced by separating aerated mixed liquor into a low suspended solids content first aqueous medium of relatively low phosphate content and a first solids concentrate comprising sludge rich in phosphate-containing-material, acidifying the first solids concentrate to a pH in the range between 4 and 6À5, separating the acidified sludge concentrate into a second low suspended solids aqueous medium and a second sludge concentrate of solids content greater than that of the first sludge concentrate, mixing the second sludge concentrate with a sufficient volume of the first aqueous medium to form a diluted sludge concentrate and separating the diluted sludge concentrate into a low solids content final effluent and a final sludge concentrate of relatively low phosphate content which is recycled. The separations may be effected by settling, flotation, filtration or centrifugation.
