Title: Improvements in or relating to woven pile fabrics
IPC: D03D15/00
Filed: 1928-03-21
Abstract: 313,992. Shepherd, F. L., and Cords, Ltd. March 21, 1928. Pile fabrics are woven with two or more wefts of different characteristics and affinities for dyestuffs, each weft acting at parts as a ground pick and at other parts as a pile pick so that after treatment in a two colour dye bath, pile portions differently coloured are produced. A weft of viscose artificial silk V for example is floated at certain parts as indicated by rectangles in Fig. 2, and at other parts of the fabric forms ground, a second weft of cellulose acetate artificial silk C being also floated at certain parts and forming ground at other parts, one weft forming ground at those parts of the fabric where the other is being floated. When the pile flats are cut, pile portions of viscose are formed in the part A, pile portions of cellulose acetate at the part B, and plain portions, where neither weft is floated, are formed at the part C. The fabric after being bleached or scoured may be treated in a dye bath of Direct Sky Blue GS, which dyes the viscose but not the cellulose acetate and S.R.A. Orange II, which dyes the cellulose acetate. A weft may also be used which is woven as a ground pick throughout. The wefts may be preliminarily treated in known manner to increase their affinity for or resistance to particular dyestuffs. The Provisional Specification refers to the use of cotton, linen, or wool warps.

Title: Improvements in or relating to tubular containers for electrical condensers or other apparatus
IPC: H01G2/10
Filed: 1944-05-08
Abstract: 586,682. Condensers. SPORING, P. A., and TELEGRAPH CONDENSER CO., Ltd. May 8, 1944, No. 8682. [Class 37] A tubular container 7 for an electric condenser 1 or other apparatus is closed at one or both ends by spinning over the edge 8 to grip a resilient disc 5 between the edge and some portion of the enclosed apparatus. In one example, Fig. 2, the resilient discs 5 bear on discs 9 of, e.g., " Bakelite " (Registered Trade Mark), one of which bears against an internal beading or series of projections 10 and the other against the edge of a ceramic cup 1. The discs 5 are of natural or synthetic rubber, e.g., neoprene, and have central bosses 6 to ensure efficient sealing of wire leads 3. The spun-over edge 8 makes an angle of about 45 with the axis of the tube to enhance the grip of the discs on the wires 3. The ceramic cup has internal and external metallic coatings, only the latter, 2, being visible in the drawing, and the wires 3 are soldered to the coatings, as at 4. In another example, Fig. 1 (not shown), the edges of the container are spun over at right-angles to grip the margin of the resilient discs against a ceramic dielectric plate. In a rolled condenser the wire lead may be formed into a spiral which forms a bearing surface for a resilient disc. The container is preferably made of aluminium in the case of electrolytic condensers, but is otherwise brass &c. which is advantageous when one end of the container is closed except for a small hole in which the wire lead is soldered. If a resilient disc is employed at each'end, one disc may be made conductive by incorporating in it a conductive powder as so to effect electrical connection between the wire and container. The container may be spun over at one end prior to the insertion of the apparatus. The discs may be coloured &c. to distinguish polarity in the case of electrolytic condensers &c.

Title: A method of conching chocolate and the like masses, and a machine for carrying out this method
IPC: B01F27/93
Filed: 1950-04-06
Abstract: 685,149. Mixing-appliances. MIKROVAERK AKTIESELSKAB. April 6, 1950 [April 9, 1949; Nov. 28, 1949], No. 8753/50. Class 86 [Also in Group VI] In conching chocolate and like masses, the mass is set in whirling motion and spread out in a thin film by centrifugal force to obtain a large surface on which air can act. Discs 13, 14, forming two sets, are clamped between spacers 12 on shafts 7, 8 with the discs of one set overlapping those of the other, the edge of each disc 13, 14 respectively being received in a groove 16, 18 in a stationary ring 15, 17 such that the clearance between each disc and the bottom of its groove is just sufficient to allow rotation of the disc. Outlets 19, 20 in the rings 15, 17 are directed towards the shafts 8, 7 respectively. In use the mass enters the jacketed casing 1 at 3, falls on to the uppermost rotating disc 13 near the centre thereof to be spread in a thin film over it and is flung into the groove 16; it then flows through the outlet 19 to hit against the uppermost spacer 12 and drop on to the uppermost disc 14 near the centre thereof, whereupon the mass is again spread out to pass via the outlet 20 on to the next disc 13 until finally, having passed over all the discs, it flows through an outlet 4. Meanwhile air, entering at 5, passes through openings 21 in filling pieces between the rings 15 (or in the rings themselves), over the discs, and through similar openings 22 to an outlet 6. In a modification, Fig. 3 (not shown), the ducts 23, 24 above the air passages 5, 4 are each partitioned into an inlet and an outlet for the adjacent set of discs; the inlets communicate with tubes which are directed towards the shafts 7, 8 and are secured to the rings 15, 17 to extend between the discs, the ends of the tubes being bent round so that the air flows out in the same direction as that in which the mass is moving; the air flows to the outlets through openings in the rings 15, 17. Alternatively air may pass via a single inlet to all the tubes and exhaust through a single outlet. The correct temperature of the mass is maintained by adjusting the temperature of the air current and of the water or steam in the jacket 2. The shafts 7, 8 may be hollow in which case air may be supplied to them to pass through openings in the shaft walls and flow over the discs 13, 14. The discs may be corrugated or waved radially or concentrically to increase their effective surface area, and may have circumferential teeth or the like for crushing and grinding the mass. A single set of discs may be used, each disc being encircled by the upper end of a funnel which discharges on to the centre of the next disc. Alternatively a single drumlike body may be provided with a plurality of radially extending fins over which the mass is successively spread.
