Title: A process and means for preparing textile slivers for dyeing
Inventor: BARLOW RONALD
IPC: B65H54/76
Filed: 1965-12-03
Abstract: 1,117,756. Sliver cans. KEBROYD MILLS Ltd. 13 Jan., 1967 [3 Dec., 1965], No. 51337/65. Heading D1F. [Also in Division B8] In a process of packaging textile slivers to facilitate dyeing, the slivers 7 are first consolidated in a can 1 having a loose bottom 3 whereupon the consolidated sliver is forced into a tubular member 6 closed at one end at 11, which member 6 is then closed at the other end to form a package. As described, a filled can, having stirrups 5A spring urged against a knitted, or reticulated sleeve 6, is conveyed to a position over a pneumatically operated ram 9. whereupon the sleeve 6 is manually knotted at one end at 11. An upper ram 10 is moved downwards and the lower ram 9 moved upwards through the can to lift the base 3 and compress the slivers against the head of the now stationary ram 10. When a predetermined density has been achieved, both of the rams 9, 10 are moved upwards to eject the compressed sliver from the can into the sleeve, which is simultaneously drawn up off the can. After manually inserting skewers (12) through the sleeve 6 along grooves 4 in the top of the base 3, the lower ram 9 and the base 3 thereon are descended, the upper end of the sleeve being gripped in the elevated position by, for example, a cage (4) attached to the upper ram 10 (see Specification 1,117,757). Finally, the sleeve below the skewers (12) is manually gathered, sealed by a detachable plastics disc and severed by a heated blade, after which the skewers are withdrawn and the package manually removed from the upper ram 10. After dyeing and placing the package in a hydro extractor, the slivers are removed from the reticule, dry heated and balled or formed into tops.

Title: Method of operating a gas turbine
IPC: F23R3/40
Filed: 1972-11-09
Abstract: 1415530 Gas turbine plant ENGELHARD MINERALS & CHEMICALS CORP 9 Nov 1972 [10 Nov 1971] 51855/72 Headings F1G and F1L A method of operating a gas turbine comprises partially oxidizing a carbonaceous fuel, which when burned with a stoichiometric amount of air has an adiabatic flame temperature of at least 3300‹F, and then effecting further oxidation of the fuel at a temperature of between about 1500 and 3000‹F whilst the fuel/oxidant mixture undergoes expansion in the turbine. In one arrangement a gas turbine plant comprises a centrifugal compressor 12 supplying air to a region adjacent mixing vanes 22 where a hydrocarbon fuel, e.g. propane or naphtha, is introduced via line 21, the fuel/air mixture then flowing through a pre-heater 25 to a combustion catalyst 30. The latter is of insufficient volume to cause complete oxidation of the fuel but further oxidation occurs as the mixture expands through the nozzles 31 and rotor 14 of a single or multi-stage turbine on its way to exhaust duct 24 and heat exchanger 25. Catalyst 30 is heated at starting by fuel injected through line 38 and ignited by igniter 36, a thermocouple sensing the catalyst temperature. The catalyst 30 and plant fuel may be as described in Specification 1395422 and the plant conditions such as oxidant/fuel ratio, mixture velocity &c. are generally as specified in that Specification or in Specification 1395986. Oxidation in the catalytic zone or in the turbine may take place with or without a flame. In a modification the initial partial oxidation is effected by spraying fuel into the combustion zone without the provision of a catalyst. In this case cooling air may be mixed with the products while avoiding substantial completion of the combustion process before the gases reach the turbine. The products in exhaust duct 24 may be still further oxidized by thermal or catalytic means to reduce atmospheric pollution.

Abstract: 1,125,388. Packaging stockings. "BEGY" SOC. EUROPEENNE DE BAS SANS COUTURE. 7 Dec., 1965 [8 Dec., 1964], No. 51938/65. Heading B8C. In a package for stockings, each individual rolled or folded stocking is enveloped in a wrapper comprising an opaque portion carrying inscriptions and/or designs, and at least one transparent window. The wrapped stockings are then enclosed in separate pockets of flexible transparent material which are detachably joined together in a continuous strip. In the embodiment, a rolled stocking 16 is wrapped in a tubular wrapper 24, made from a paper sheet 26, glued at its longitudinal edges to a transparent cellulose sheet 28. These packages are then either placed in open-ended pockets 14 formed by heat sealing two transparent sheets, or a single folded sheet, together along one longitudinal edge 20 and transversely at 22, the filled package being closed by sealing the second longitudinal edge. Alternatively the packages 24 may be placed between two sheets or a single folded sheet before the welds 20, 22 are made. The transverse welds 22 may be perforated along their mid sections to facilitate separation of individual stocking packs.

Abstract: 1,254,899. Transistor logic circuits. NORTH AMERICAN ROCKWELL CORP. 23 Oct., 1969 [4 March, 1969], No. 52050/69. Heading H3T. [Also in Division H1] In a four-phase logic circuit comprising fieldeffect transistors, a field-effect transistor 13 gates the input to a selectively switched semiconductor capacitor 32. This capacitor comprises a first electrode 15 contacting an n-type region formed in a p-type substrate and a second electrode 7 which is insulated from this substrate by an insulating layer and arranged so that when a voltage is applied to it an inversion layer is created in the substrate under the insulating layer and continuous with the N-type region forming a capacitor comprising electrode 7, the insulating layer and the inversion layer, but when ground is applied to it the inversion layer is eliminated and the capacitor is discharged. Thus it can be arranged that the gating capacitor 32 is not, or is, present according to whether the signal applied to it grounds terminal 7 or not respectively.

The liquid passes down the column in countercurrent to water vapour generated by heating a portion of the stripped effluent with low-pressure steam in heat exchanger 89. The gas recovered from the fractionating column and the throttle stages is cooled, compressed and returned to the isotope exchange process.

Title: Improvement in a phenol-aldehyde dicyandiamide binder composition
Inventor: STALEGO JOSEPH PETER
IPC: C08K5/315
Filed: 1965-12-14
Abstract: A hardenable phenol-aldehyde resin composition which is an aqueous dispersion containing 1 to 50% solids consists essentially of a heat-hardenable phenol-aldehyde resole resin having no more than 3.6% by weight of free aldehyde, and from 10 to 120 parts by weight of unreacted dicyandiamide for each 100 parts of the hardenable phenol-aldehyde resin, on a dry solids basis.  The dicyandiamide is most suitably dissolved in water at an elevated temperature and the resulting solution is mixed with the phenol-aldehyde resin plus any other optional constituents. Suitable phenol-aldehyde resins are phenol-formaldehyde partial condensation products and phenol-amino compound-formaldehyde condensation products.  The composition may be cured by heating during which the dicyandiamide is said to function as a cross-linking agent for the hardenable phenolic resin by reacting with methylol groups.  Optional constituents which may be added to the composition are ammonium hydroxide, ammonium carbonate, gamma-aminopropyltriethoxysilane, a mineral oil emulsified with stearic acid, ammonium sulphate and a natural resin derived from pine wood.  The compositions are suitable for binding glass and other vitreous fibres (see Division D1).ALSO:A mat of bonded, intermeshed glass fibres may be produced by introducing a heat-hardenable phenol-aldehyde resole resin binder composition into a fluid mass of the glass fibres which are being projected towards a collecting surface, depositing the projected fibres in association with the resin binder composition in a wool-like mass and heating the mass to harden and cure the resin binder composition.  The heat hardenable phenol-aldehyde resole resin binder composition is an aqueous dispersion of 1 to 50% solids consisting essentially of a heat-hardenable phenol-aldehyde condensation product having no more than 3.6% by weight of free aldehyde and from 10 to 120 parts by weight of dicyandiamide per 100 parts of the hardenable phenol-aldehyde resin.  The binder composition is suitably sprayed into a forming hood through which glass fibres are projected onto a foraminous conveyor and the wool-like mass so produced is cured at about 450 DEG F under pressure to produce a board like product.
