Abstract: 362,849. Cylindrical plywood articles. SCHLESINGER, G., 9, Korolingerplatz, Charlottenburg, Berlin. Sept. 2, 1930, No. 26171. Convention date, Sept. 7, 1929. [Class 145 (ii).] In making hollow plywood vessels from veneers, a continuous strip of veneer 1 is attached to a revolving drum 6 by a pivoted bar 26a, and has a second veneer 3<1> laid on it from a reel 4. Adhesive is applied to both faces of the veneer, either from the tank 12 or by strips of adhesive 14. The veneer 3<1> has its grain at right-angles to that of veneer 1 and its length is equal to the circumference of the drum 6 so that after one complete circuit veneer 1 forms the inner ply of a. 3 plyvessel. Knives 8, 11, cut off the lengths as required. The veneers are pressed against the drum by a steel band 17 kept taut by the load 22. The drum 6 and the band 17 are heated to melt the adhesive. To facilitate removal of the finished vessel the drum is reduced in diameter by the hand-wheel 30 moving a conical internal member axially, thus drawing inwards the bars 26b, 26c and 26d. Conical vessel can be similarly formed on a conical drum. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a method of forming a conical plywood vessel from one sheet of veneer by forming a sector 154, Fig. 4 (Cancelled). A method of cutting a veneer from a conical log is described. This subject-matter does not appear in the Specification as accepted.

Filed: 1966-06-14
Abstract: 1,153,001. Colour images; colour screens. GENERAL ELECTRIC CO. June 14, 1966 [July 16, 1965], No. 26439/66. Headings G2C and G2H. [Also in Division H1] Multi-colour images are prepared by imagewise exposing a supported transparent thermoplastic layer through a filter composed of red, blue, green and optionally black areas to break up the image into small areas of primary coloured light which form a charge pattern on the surface of the layer, and heat-softening the layer to form a deformation image composed of ridges and valleys. In the particular embodiments described, the charge image is formed by either (a) exposing a thermoplastic layer (4) (e.g. of polystyrene) containing a photo-ionizable substance (e.g. iodoform) Fig. 1 (not shown); (b) uniformly electrostatically positively charging a thermoplastic layer (13) containing a photo-conductor, exposing, and uniformly electrostatically negatively charging the layer to give a photographically positive image, Fig. 2 (not shown); or (c) uniformly electrostatically charging a thermoplastic layer which is adjacent a photo-conductive layer, and exposing Fig. 6 (not shown). The multicolour image may be broken up into small primary coloured areas by a transparent colour screen composed of small areas of red, green, blue and black Figs. 1-6 (not shown), or by placing Fig. 7 a lenticular screen 36 adjacent the thermoplastic layer 39, and projecting an image through a filter 30 having red, green and blue areas 31 to 33, on to the lenticular screen 36, to expose the underlying thermoplastic layer. The coloured images produced may be viewed using a Schlieren system in conjunction with the colour filter system used to prepare the image. In process (b) above, the charging and exposure may be controlled so that the grooves formed on heat development extend completely through the thermoplastic layer (23, Fig. 3, not shown), and, if the thermoplastic layer is partially opaque, the resulting image may be viewed directly. The colour screens used may be prepared by either (a) dusting a tacky glass plate with a mixture of 13-25Á particles of starch or resin dyed red, blue and green Fig. 4 (not shown), and filling the interstices with graphite or carbon black; (b) laminating sequentially red, green and blue sheets having a thickness of 13-100Á either using a black adhesive or separating each set of sheets with a black sheet Fig. 5 (not shown), and slicing perpendicular to the laminations; or (c) laminating together with black adhesive a series of screens produced as in (b) and then slicing perpendicular to the laminations to give a screen wherein each element is a square or rectangle.

Abstract: 1304976 Composite filaments; fibrillation KANEGAFUCHI BOSEKI KK 19 April 1971 [7 April 1970] 26486/71 Heading B5B [Also in Division D1] A composite filament is made by feeding a first polymer B axially into a conduit, in the form of at least two laminµ extending radially from the centre to the periphery of the conduit, and feeding a second polymer A into each of the segments of the conduit defined between the laminµ and extruding the composite stream through an orifice substantially without disturbing the arrangement of the polymers. The spinneret used may have a distributer block 1 in contact with the upper surface of the spinneret plate 20, the block having slit-like outlet passages 10 which communicate with a polymer supply duct 9 and radiate from the centre line of conduit 21. The block and/or the upper surface of the plate 20 has passages 11 which connect polymer supply ducts 4 and 7 to the conduit 21 at locations between the passages 10. The laminar polymer arrangement is extruded at 22. Passages 10 may alternatively be defined by lines of closely spaced small holes. The block 1 may be linear (as shown) or annular, or each conduit 21 may have a separate circular or polygonal block. An additional passage 10 may radiate from the centre-line of the conduit, but without extending to the periphery. The orifice 22 may be non-circular, e.g. Y-shaped. In an alternative arrangement the ducts 11 define the radiating lamina-forming passages and passages 10 are then a plurality of small holes intermediate the ducts 11. The filaments may be as shown in Figs. 1-6. In examples, the component A is polyethyleneterephthalate and B is polycaproamide, polyethylene oxide, or a copoly - (caproamide - hexamethyleneisophthalamide). Other polymers are listed, the A/B arrangement being preferably such that A is water-insoluble and B is water-soluble, or A and B are soluble in different organic solvents, or A and B are of low compatibility, whereby the composite filament may be fibrillated by dissolving out one component (usually B) or by mechanical working. In Example 3, the copolyamide above is removed using formic acid.

Filed: 1977-06-24
Abstract: 1530860 Collection of gases and fumes emitted by a converter CLESID SA 24 June 1977 [28 July 1976] 26662/77 Heading F4X Gases and fumes emitted by a tiltable converter 1 are collected by an enclosure 5, 8 which is of sufficient dimensions to allow tilting of the converter and to surround at least that part of the converter located above the horizontal plane containing the axis of tilt. The enclosure 5, 8 is provided with doors 6, 7 and is connected in an airtight manner to a fixed suction duct 11  by means of part 8 which, as shown, is removable. The duct 11 leads the gases and fumes via a dust extractor 12 and fan 14 to a flare 13 at which they are burnt. Detectors 16 and 17 detect the pressures of gases in and outside the enclosure and are connected to a regulator 19. The regulator 19 controls a damper 15 so as to adjust the draught in the suction duct for maintaining the difference in the pressures detected by the detectors 16 and 17 (represented by electrical signals) at a first predetermined value (represented by an electrical signal S): When the converter is in a vertical position (e.g. during refining) and at a second predetermined value (represented by an electrical signal S 1 ) when the converter is in a non-vertical position (e.g. during charging). During refining, the emitted gas is rich in carbon monoxide. By adjustment of the value of So, the amount of air which enters the enclosure 5, 8 may be controlled so that only a very low percentage of the gases as they leave the converter is burnt. S 1  may be such that there is maximum draught for sucking away fumes.

Filed: 1925-10-29
Abstract: 266,777. British Celanese, Ltd., and Ellis, G. H. Oct. 29. 1925. Designs, producing.-Effects or patterns are, produced on fabrics made from or containing cellulose acetate by the local application of a substance or substances which modify the delustring action of hot or boiling aqueous media or steam, and thereafter subjecting the printed material to the action of these agencies. The substances to ba applied locally may be mechanical resists such as waxes, resins, gums, pigments &c., or they may be solvents for cellulose acetate or substances which dissolve therein, such as phenols. chlorophenols, aromatic amines or substituted amines, arylhalides, alkylhalides, aliphatic, alcohols and their chloro derivatives, esters, aldehydes, ketones, hydrogenated hydrocarbons and phenols, and cyclic bases. Depending on the conditions these solvents or solutes may in some cases act to conserve, the lustre, whilst in other cases they accelerate the delustring action of aqueous media or steam. The solvents or solutes may be used in the form of aqueous solutions or pastes, or dissolved in non-solvents for cellulose acetate such as benzene or xylene, or dispersed in aqueous media. The process may be applied to dyed or undyed goods; and since the delustred portions show a different behaviour towards dyestuffs, differential effects can be produced by a suitable choice of the latter; thus the delustred material shows a considerably altered affinity with respect to many water-soluble dyestuffs such as Capri blue, whereas delustring does not affect The rate of dyeing when employing the methods described in Specifications 219,349, 224,925, 242,393 and 242,711, [all in Class 2 (iii).

Abstract: 940,470. Fluid pressure apparatus. PARKER-HANNIFIN CORPORATION. July 17, 1962, No.27380/62. Heading F1P. A fluid pressure actuator comprises a piston 14 reciprocable within a bore 12 of a cylinder having closure means 13 provided with a passage 22 for fluid introduced and expelled from the bore, sleeve means 30 of rigid material having a central opening 36 connecting the passage and bore and closable by a part 15 carried by the piston when the piston is near the closure means, and a resilient packing 31 carried by one of said means and having a flexible lip 47 which normally closes a flow path between the passage and bore and is responsive to pressure of fluid from the passage for opening the flow path. The sleeve means is retained with slight and play in a counterbore 27 of the closure means by a circlip 32 and has a pair of flanges 38, 39 spaced with a slight clearance from the counterbore. The packing 31 is located between the flanges and has a pair of lips 47, 48 which normally bear against the sleeve and counterbore. As the piston 14 moves to the right, the part 15 enters the opening 36 in the sleeve to prevent flow from the right-hand chamber 20 of the actuator through the opening, the pressure in the chamber acting to firmly press the lips 47, 48 into engagement with the counterbore 27 and sleeve 30 so that the fluid in chamber 20 can only pass to the passage 22 and port 17 at a rate determined by a needle valve 25 in a by-pass passage 23, 24. When fluid is supplied to the port 17 to move the piston to the left, the fluid, in addition to flowing past the needle valve 25, also passes through an annular passage between the part 15 and passage 22 and a slot 44 in an annular extension on the sleeve to act on the lip 47 which moves from the counterbore 27 to permit the fluid to pass through a gap in the circlip 32 into the chamber 20 so that the piston quickly moves from its cushioned position. In an alternative embodiment, the inner ends of the flanges 38, 39 of the sleeve have holes to permit fluid to flow on the inside as well as the outside of the packing to the chamber 20.
