Abstract: 889,995. Flexible pipes. POWER AUXILIARIES Ltd. Oct. 2, 1959 [July 22, 1958], No. 23475/58. Class 99(2). [Also in Group XXXVI] In a flexible conduit having mutually isolated duct passages, an inner flexible conduit element 17 is arranged coaxially in an outer flexible conduit element 1, a fluid path being provided between them by one or more helically wound spacer cables 19. As shown, the outer conduit comprises corrugated metal tubing 1 enclosed by a braided metal sheath 3 and the inner conduit a hose-17 of flexible plastic e.g. polythene enclosed in a braided metal sheath 18, but it may take the same form as the outer conduit. The inner conduit is spaced coaxially from the outer conduit by stranded cables 19 wound helically, on which beads 20 are spaced by lengths of closely coiled wire 21. An electric cable (not shown) may pass through the core of the inner conduit where it may be located by spacer cables.

Abstract: 1431776 Retro-reflector ASSOCIATED ENG Ltd 6 Aug 1973 [8 Aug 1972 17 May 1973] 37022/72 and 23683/73 Heading G2J [Also in Divisions G4 - G6] A reflective sign, for use on road surfaces or vehicles, comprises an array of elements 10 each having a convex focusing front surface 11 and a concave focusing reflective rear surface 12 whose centres of curvature coincide such that incident light is reflected back along its path 14. The rear surface 12 is ranked with alternate reflective and non-reflective bands 17, 18 positioned such that light from an approaching source 15 is alternately reflected and not reflected as its image traverses surface 12. Depending on the position of bands 17, 18 on surface 12, light is reflected with a pulsating effect at a certain predetermined range of source 15: Thus, elements 10 may be placed in an array to provide different pulsating symbols in reflected light as the range of source 15 changes.

Abstract: 1,039,507. Valves. BALZERS PATENTUND LIZENZ-ANSTALT. June 4, 1965 [June 18, 1964], No. 23875/65. Heading F2V. In an ultra-high vacuum tight closure or valve capable of repeatedly broken sealing between a sealing body or valve member 2 and a seat 3, the valve member engages the seat on a narrow band area with such force that the necessary vacuum tightness is established owing to plastic flow of the materials of the valve member and seat. These parts consist of a material, e.g. a heat resistant nickel alloy whose rate of plastic deformation remains substantially constant up to a temperature of 450‹ C., being the temperature for de-gassing when evacuating. The yield point of the material also remains substantially constant.

Title: Improvements in or relating to the production of molecularly modified lard
IPC: C11C3/10
Filed: 1954-08-17
Abstract: <PICT:0774547/III/1> In the removal of spent catalyst and side products from the reaction mixture obtained in the molecular modification of lard by treatment in the liquid phase with an alkaline inter-esterification catalyst, the reaction mixture is continuously passed to a mixing zone and agitated with an added pre-determined quantity of hot water to kill the catalyst, hydrate the side products, mainly soaps, and form an emulsion, and the emulsion is then continuously passed to a heating zone and heated to 160 DEG -180 DEG F. to break it; finally, the aqueous phase containing the impurities is separated from the purified modified lard.  In a suitable plant liquid lard from a tank 11 is preliminarily purified in a tank 14 with diatomaceous earth and charcoal at 180-200 DEG F., filtered in filter 22 and stored in liquid phase in a tank 24.  The lard, after drying in a vacuum drier 30, is then fed to either of the reactors 34, 35 for the interesterification treatment, preferably using sodium methoxide as the catalyst in a quantity of 0.5-1 per cent by weight of the lard. The reaction mixture is kept liquid at 120-200 DEG F. for 2 to 60 minutes with agitation, and then after passing through an air separator 54, is supplied to a high-speed mixer 64 through a rotometer 60 connected to a ratio controller 62, which controls a valve 65 to regulate a quantity of hot water supplied through line 66 to the mixer 64.  A proportion of 5 per cent by weight of water is preferred.  The hot water at 140-150 DEG F. passes through a rotometer 70 also connected to the ratio controller 62.  The reaction mixture and water are vigorously agitated in the mixer 64, and the emulsion formed is then passed to a heating zone 72 and held therein for 1-2 minutes at 160 DEG -180 DEG F., controlled steam heating being used.  The broken emulsion then passes to a centrifuge 80 for removal of the aqueous phase with impurities.  The lard then passes to a washing tank 85, for removal of residual catalyst and soap by adding water at 150 DEG F. and in the proportion of 10 per cent by weight.  Part of the water-lard mixture is passed to centrifuges 96 and part is returned to the tank 85.  The purified lard passes to a vacuum drier 110 and then to a deodorizer 114 for recovery of the purified modified lard at 116.  Specifications 710,001 and 763,299 are referred to.

Abstract: 1529226 Pipes BEKAERT SA NV 24 May 1976 [5 June 1975] 24300/75 Heading F2P Reinforced plastics articles, e.g. pipes, are characterized in that the reinforcing material comprises at least one layer of a combination of glass fibres and steel cord (i.e. at least two wire strands twisted together) with fibres and cords connected in the same direction. The steel cord may be in the form of woven or non-woven fabric or alternatively woven into a fabric with the cord constituting the warp and a synthetic fibre, e.g. nylon, polyester constituting the weft: the cord may itself be a coreless structure of twisted wires or comprise a core strand with a plurality of further wires twisted thereabout. The plastics material may be thermoplastic or thermosetting; examples of the latter being polyester, epoxy phenolic, melamine-formaldehyde, resorcinol-formaldehyde, and ureaformaldehyde resins or polyurethanes as well as thermosetting copolymers, and may in addition contain a dry filler, e.g. inorganic material constituting up to 60% of the total. Several such reinforcing layers may be combined via sheet, preferably separated by a reinforcing substructure comprising at least one glass fibre, e.g. resin impregnated mat layer. In a filament winding process shown for forming a reinforced plastics article as described, parallel resin impregnated glass rovings 1 and non-impregnated steel cords 2 are advanced to a guiding system 3 which moves axially of a mandrel 4 simultaneously laying the cord and glass fibre rovings in axial strips which are helically bound by threads 5 from a winding system 6 which moves with the system to effect the embedding of the cords into the rovings after each strip is layed and bound, the system returns to the initial position and the mandrel is rotated sufficiently to present an adjacent area for receiving a further strip. Alternatively (Figs. 5, 6, not shown) the axial strips may be carried by circumferentially arranged bobbins on a guiding system in the form of a ring like framework and layed simultaneously as the system is threaded down the mandrel. In an alternative process suitable for producing tapered tubes (Fig. 3, not shown) a frustoconical mandrel is employed; the reinforcing layer being shaped to the development of the mandrel surface and sandwiched between a support table and the mandrel which is rotated to wrap the layer thereabout.
