Title: A method of making tubular bodies of cast synthetic resin
Inventor: PROUD STANLEY HARRY RUSSELL
IPC: B29C33/50
Filed: 1966-04-25
Abstract: 1,139,597. Casting tubular bodies. BRITISH INSULATED CALLENDER'S CABLES Ltd. 24 April, 1967 [25 April, 1966], No. 18013/66. Heading B5A. Tubular bodies of synthetic resin with an open-ended or blind bore are formed by covering a mandrel with a layer of cellular elastomeric material and then optionally with a layer of non-cellular elastomeric material, casting resin around the coated mandrel and removing the formed tube from the mandrel and coating. The foam serves to reduce stresses set up in the tube as the resin sets. The elastomeric foam may be a silicone, butyl or ethylene-propylene rubber and may be applied by helically winding a tape of foam material, applying as a sheet or preformed sleeve or by foaming in situ. The non-foamed layer is preferably applied as a sleeve. Both the mandrel and the outer side of the foam material or its coating may be greased before casting the body, which is preferably formed from an epoxy resin. The cast tube and the foam layer may be removed together from the mandrel and then separated by admitting compressed air to the interface. If a blind tube is formed the foam material should cover one end of the mandrel.

Title: Improvements in and relating to cupola furnaces
IPC: F27B1/08
Filed: 1929-06-12
Abstract: 334,917. Bentley, L. A. June 12, 1929. Cupola furnaces.- In a cupola furnace the air supply is passed around the shaft in counterflow with the combustion gases, and a part is delivered for secondary combustion through a large number of small openings, so that the air enters in such a diffused state that it will not attack the solid fuel of the ' charge. In the furnace shown the shaft comprises three concentric casinos of which the innermost 1 forms the shaft proper while the two outer ones 7, 8 form air heating jackets connected at their upper ends, the air passing upwards through the outer one and downwards through the inner. The shaft 1 is suspended by bolts 3 from overhead supports 2, and by this means the annular tuyere gap between the lower end of the shaft and the metal well can be adjusted to vary the primary air supply, a concertina joint 10 being provided on the outermost casing 17 to permit this adjustment. In the melting-zone the shaft 1 is lined with refractory material 5, and above this zone the shaft is formed with numerous small perforations 30, which preferably increase in number at the higher levels of the shaft. Some of the holes may be formed to receive interchangeable nipples 31 or blanks so that the air supply for secondary combustion may be varied according to conditions. Fins 6 may be carried by the shaft 1 to promote absorption of heat by the incoming air. In modified constructions the two inner casings are formed by H-section members bolted together to form a shaft of rectangular section, or secured by straps when the shaft is circular. Specification 4836/82 is referred to.

Title: Method and apparatus for operating flowing oil wells
IPC: E21B43/38
Filed: 1934-06-20
Abstract: <PICT:0441684/III/1> <PICT:0441684/III/2> <PICT:0441684/III/3> <PICT:0441684/III/4> To increase the production of oil from oil wells, the oil is agitated within the eduction tube to release more gas than is normally released by pressure reduction on the oil flowing into the well; at least part of the released gas may be separated and collected under pressure and then returned to the depleted upper part of the oil sand.  As shown diagrammatically in Fig. 1, oil passes from the oil sands through a gas trap 74 and rises through pipe 79 through one or more gas separating and collecting stages each comprising a series of bells 56 with apertured upper ends and centrifuging elements between the bells comprising vaned wheels 63 rotated by the flowing oil; the oil is agitated in passing through the apertures in the bells while passage through the vaned wheels 63 causes collection of gas in the central lighter column of oil, the heavier outer column of oil passing round the bells to the outlet pipe 28.  At the end of each separating and collecting stage, the central column of oil enters a chamber 51 in which the gas separates and, as its pressure increases, passes through a nonreturn valve 41 to the oil sands.  In Fig. 7, the gas collection chamber 110 is annular, the gas passing through ports 101 past valves 102 and through slots 108 to the oil sand; oil flows out through tubing 112 to which it passes downwardly through semi-cylindrical channels 116 and ports 115.  With this form of apparatus, agitating means may be employed comprising alternate fixed sleeves 145, Fig. 12, with inclined vanes and intermediate rotatable members 150 with oppositely inclined vanes.  In Fig. 10, after each centrifuging stage, a heavier outer column of fluid passes round an upper bell 121 through ports 127 to the next rotor 63, a lighter central column passing through the bell and through ports 125 to points nearer the centre of the rotor.

Abstract: 393,763. Cables. NAAMLOOZE VENNOOTSCHAP HOLLANDSCHE DRAAD-. EN KABELFABRIEK, 10, Hamerstraat, Amsterdam. June 28, 1932, No. 18296. Convention date, Aug. 24, 1931. [Class 36.] An air-insulated cable, particularly for conducting radio-frequency currents, comprises a conductor supported within a screening covering, such as a lead. sheath, by one or more layers of highly open insulating braidings, of which the layer adjacent the conductor is composed of four strands at the most. The strands may be of cotton, silk, hemp, paper cord, or may be in the form of a rubber coated thread. To decrease the resistance of the screening covering, a copper tape may be disposed against the inner wall of the covering. In the construction shown, a twin conductor cable has stranded conductors 1, 8 carried within a lead sheathing 6 having ducts 5, 7 for the separate conductors. Braided strands 2, 3, 9, 10 support the conductors in the ducts. To prevent electrical contact between the conductors and the inner wall of the lead sheathing, the conductors may be coated with rubber before the braiding is applied. In a modified construction both conductors are carried within a common circular lead sheath and a plurality of layers of braidings surround each conductor, the layers being mutually separated by helically wound paper layers.

Filed: 1945-07-17
Abstract: 595,865. Counting-apparatus. TRIPP, G. H. July 17, 1945, No. 18305. [Class 106 (i)] Means for counting articles such as pills into batches and delivering them into receptacles comprises a supply hopper disposed above a horizontal counting plate rotatable about a vertical axis and having groups of holes with a stationary table disposed below having one or more delivery apertures fitted with shoots, but otherwise forming with the said holes pockets to receive the articles such that the articles are discharged into the shoots before the holes again pass below the hopper to be charged directly therefrom. A stationary table 1 has two delivery apertures 24 and two extensions 2 by which it is supported by frame members and upon which is supported a supply hopper 15. An electric motor drives, through a belt, pulley and reduction gearing 9, a vertical spindle 10, which passes through the table 1 and carries a counting plate 13 having four groups of holes 14. Thus, as the counting plate rotates, a group 14 passes alternately through the hopper 15 to be charged with a batch and out over an aperture 24 to deliver it. In order suitably to direct the articles within the hopper, the clearance between the counting plate and side walls 16 is small and fittings 19 may be fixed along their lower edges, while the end walls 17 may be shaped to the curvature of the counting plate or have lining blocks 18 so shaped and presenting an inclined upper surface, a conical baffle plate 20 is fixed to the spindle 10 and the upper part of the hopper may be divided longitudinally by a baffle board 21. Doors 23 may be provided in the side walls 16 and each delivery aperture 24 may be sealed off by a closure plate. Tunnels 27 may be fixed or removably fitted below the table 1 to register the aperture 24 and their outlets, shaped to be appropriate to the receptacles, may be closed by hinged flaps 28 against the action of leaf springs 29. The flaps may be operated by hand or automatically through the action of a cam 33 on rollers 32 carried by spindles 31 with arms 30. The cam is supported by a carrier 34 on the vertical spindle 10 and as each batch is positioned for delivery the cam is so positioned as to permit the flap-control spindles 31 to move inwards and open the flaps 28. Baffle plates may be fitted in the delivery funnels to define the course of flow. The motor, reduction gear and cam may be enclosed within a sheet metal casing 36. A control switch for the motor may be provided .for each operator such that while any switch will stop the machine, they must all be operated to start the motor.

Title: An improved method of and means for effecting the register of plates in multi-colour printing
IPC: G03F9/00
Filed: 1933-06-28
Abstract: 421,823. Printing-surfaces; underlays. MOREMENT, C. E., 180, Cranbrook Road, Redland, Bristol. June 28, 1933, No. 18339. [Class 100 (ii)] A method of accurately positioning a series of printing-plates and overlays for multicolour printing consists in taking a print from the plate, or each plate of the set of plates, for one of the colours, which plates are as usual provided with register marks, arranging the print or prints in the desired position on the top sheet of a pile of sheets held together in coincident relation, perforating the sheets through the register marks on the prints, and using the sheets separately for positioning the plates on mounting blocks or on the machine beds, and the overlays on the platens or impression cylinders. The printing-plates are provided with holes drilled through the register marks and, at the back of the plate, the holes are countersunk. To facilitate positioning the prints, the top sheet of the pile may be ruled with lines at right angles and, if the plates are to be secured to slotted metal mounts or machine beds or mounts comprising spaced wood and metal portions, a full size illustration of the mount or bed surface is also preferably imprinted upon the top sheet. Instead of mounting the prints directly upon the top sheet of the pile, they may be secured to a cardboard or other template which is then positioned upon the pile. When mounting the plates on wood mounts, the perforated sheets are placed upon the mount and headless chamfered register pins are driven into the mount through the perforations in the sheet. If the plates for the second and subsequent colours require slight adjustment to compensate for stretch or shrinkage of the paper after the first impression, this may be effected by driving the register pins into the mount until their chamfered ends lie in the countersunk portions of the holes in the plates. When the plates are to be secured to metal mounts or machine beds, small segments of the plates extending from the register holes to the edges of the plates are cut away and small triangular pieces of metal are secured to the perforated sheets each with an angle coinciding with a perforation. These pieces of metal, after the sheet has been secured to the mount or bed, facilitate sighting the plates into proper position prior to clamping up in the usual way. Overlays prepared from the plates and showing the register marks may have segments leading to these marks cut away to enable them to be accurately positioned upon and to be secured by adhesive to the perforated sheets. These sheets are then secured in proper position on the impression cylinder or platen. To enable this position to be determined, a print may be taken on to the top packing sheet of the impression cylinder or platen from the tops of a pair of register pins on a mounting board properly positioned in the machine.

Title: Pigment dispersions for colouring viscose spinning masses
IPC: C08G14/04
Filed: 1964-05-04
Abstract: Aqueous pigment dispersions for colouring viscose spinning masses contain as dispersing agent a condensation product of (a) a water-soluble adduct of 8-25 mols. of an alkylene oxide per mol. of aromatic amine with (b) a phenol, and (c) formaldehyde, which product may be alkylated.  There are preferably used 0.5-2 mols. of phenol and 1-4 mols. of formaldehyde per mol. of aromatic amine.  Suitable starting materials are ethylene oxide or propylene oxide; aniline, toluidine or b -naphthylamine; and phenol, cresol, butylphenol, a -naphthol, b -naphthol or resorcinol.  Suitable pigments are carbon black, azo pigments, insoluble quinonoid and indigoid vat dyestuffs, phthalocyanines, bisoxazine and perylene-tetracarboxylic acid dyestuffs and quinacridone dyestuffs.  In general 0.5-1 part by weight of the dispersing agent are required per part of pigment.  The condensate may be prepared by adding the phenol and the aldehyde to the molten alkoxylated aromatic amine, followed by an acid catalyst e.g. H2SO4.  For alkylation the mixture is made alkaline and, e.g., dimethyl or diethyl sulphate is added.  On neutralization the condensation product separates in 40-60% aqueous solution from the salt lye.  In examples, pigments are ground in porcelain ball mills for 250-350 hours to give 1m  particles dispersed in a mixture of distilled water containing pentachlorophenol sodium, and a 45% aqueous solution of a dispersing agent obtained from an ethylene oxide-aniline adduct, phenol and a 30% aqueous solution of formaldehyde, and methylated with dimethyl sulphate.  Pigments used are coupling products from diazotized 3-nitro-4-aminotoluene and acetoacetic anilide, diazotized 2:5-dichloroaniline and the 2:5-dimethoxy anilide of b -oxynaphtoic acid, and from diazotized 2:4-dichloroaniline and the o-toluidide of b -oxynaphthoic acid, and copper phthalocyanine.
