Title: Improvements in, or relating to, sewing machines
IPC: D05B49/04
Filed: 1935-05-24
Abstract: 457,272. Sewing-machines. BRITISH UNITED SHOE MACHINERY CO., Ltd., Belgrave Road, Leicester.-(United Shoe Machinery Corporation ; Paterson, New Jersey, U.S.A.) May 24, 1935, No. 15118. [Class 112] The needle-thread take-up mechanism of a barbed-needle lock-stitching machine travels close to the cover of a stationary casing to prevent the thread from flying off the roll. The mechanism as shown comprises a rotating arm 16 carrying the take-up roll 14 which acts on the needle thread as it passes between the guide rolls 12, 18, to draw out a bight of thread at each cycle. The arm 16 is mounted on a shaft 26 coupled to the crank arm 34 of a driving shaft 34 by a drag link 38, pin 36 and disc 40, to impart rapid movement during the take-up stroke and a slower movement during the paying-out stroke. The guide roll 12 is mounted on a bolt 19 adjustable in a slot 22 in the take-up housing, to vary the amount of thread taken up. The roll 14 operates in a circular housing 42 with a plate 44, Fig. 2. The arm 16 carries a shield or flanged disc 46. The thread is pulled off between the narrow space enclosed between the plate 44 and disc 46, and the risk of its jumping off the roll 14 is thus minimized.

Class 23(1) [Also in Group XXV] A closure for a pressure vessel 1 having an orifice 4 comprises a conical-shaped plug 5 extending to a square-sectioned portion 7 and an integral screw-threaded portion 81 for engagement by a nut 8, a locking-ring 16, a distortable metal sealing-ring 13, and a cover 9. On assembly the plug 5 is positioned in the orifice 4 and the sealing-ring 13 placed thereon, the locking-ring 16 is received in a bayonet socket 17 of a housing-wall 15 and the cover 9 is supported in a recess 11 of the housing. The orifice is closed by tightening the nut 8, the rotation of the plug being prevented by the square-sectioned portion 7 engaging a similarshaped recess 91 in the cover 9, the sealing-ring being forced against the housing-wall 15 by the inclined face 61 of the plug and the packing-ring being relieved of axial pressure. The materials of the plug and the housing are dissimilar, the former having a higher coefficient of thermal expansion which facilitates its release from the housing. In a modification a cover also serves as a nut and has a recessed hexagonal socket to effect tightening. In a further modification the separate locking-ring is omitted and the cover provides an abutment surface for the sealing-ring.

Filed: 1963-04-18
Abstract: A method of producing hot rolled alloy steel bars, e.g reinforcement bars having a carbon content from 0.45-1.00% but preferably between 0.65-0.75% comprises cold stretching the bars in their as-rolled condition to a stress of 70-90% of their ultimate tensile strength in a known manner and stress relieving the bars within a temperature range of 485-1375  DEG F. for from 2 minutes to 6 hours.  After cooling to below 150  DEG F. the bars are removed from the furnace for further processing, e.g. cutting, preparing the ends for threading, and coating. A preferred stress relieving temperature is 600  DEG F. for 4 hours.  The bar material may also contain magnesium and chromium in amounts of less than 2% each, and be cooled to room temperature before removal from the furnace. By limiting the stretching to the figures stated the permanent elongation is said to never exceed 3%.

Title: Improved processes and apparatus for the vacuum flotation treatment of coal, ores and the like
IPC: B03D1/04
Filed: 1947-06-11
Abstract: 633,776. Froth flotation. SUTTON, W. J. June 11, 1947, No. 15394. [Class 82(ii)] In a process for the vacuum flotation-treatment of ores, coal and the like, re-treatment of the waste product, or of the clean or concentrated product, is effected simultaneously with the primary treatment as a continued operation in a single apparatus. The apparatus shown in Fig. 1 comprises a main separation chamber 1 of double conical formation. An overflow trough at the top of upper cone 2 serves to maintain a constant liquid level in chamber 1. Concentrically within the chamber 1 is a cylinder 5 which forms a re-treatment chamber with its upper edge slightly above the constant liquid level in chamber 1 and its lower end joined to a truncated cone 6 which is connected to a cylindrical outlet fitting 7 surrounding a centrally disposed outlet pipe 8 by which clean flotation product leaves the apparatus. The cylinder 5 contains a series of spaced cones 11, 12, 14, Fig. 3, which, with orifices 28 and 29 in cylinder 5, ensure the separate removal of the various products from the apparatus. Orifices 30 ensure constant level of liquid in the cylinder and chamber 1. When applied to the treatment of coal, pulp to be treated is supplied to chamber 1 by supply conduit 32, Fig. 1, branched to distributers 33. Air may be added to the incoming pulp through a diffuser 34. The refuse from this primary treatment is discharged by outlet fitting 36 and pipe 37 and is supplied to cylinder 5 by pipe 17, Fig. 3, having a tangential discharge 18, thus giving the pulp a rotary motion. As the coal-laden froth rises the rotary motion is arrested by baffles 16 and the froth overflows through orifices 26 to compartments 25 of radially-spaced launders 19. from which it is discharged by orifices 29 and pipe 8. Refuse from this re-treatment sinks through cone 14 to cone 12 and passes away by pipe 13. At the same time in chamber 1, outside cylinder 5, and in the spaces between launders 19, coal-laden froth rises and passes over lips 20 of launders 19, Figs. 1 and 5. The froth is directed by angularly adjustable guide plates 23 over screens 22, which are preferably at an angle of 45 degrees to the horizontal, and is freed of a large part of its water content which is removed by compartment 24, orifice 28, Fig. 3, cone 6, fitting 7 and pipe 10. Specification 505.688 is referred to.

Abstract: 690,360. Electric condensers. STRONG, H. V., and EISLER, P. Nov. 18, 1949 [Nov. 11, 1948], No. 15825/51. Divided out of 690,328. Class 37. Dielectric material in sheet form consists of an insulating matrix 12, Fig. 1, in which are embedded particles 11 of high permittivity so that the dielectric consists substantially of portions of the matrix material in parallel with the particles. The particles are preferably ceramic and are long and narrow flakes 16, Fig. 3, so orientated that the sheet can bend about an axis parallel with the flakes. If more than one layer of particles is used, they are substantially in contact, Fig. 2. The particles are preferably of ceramic material and may be produced by rolling on to a base to produce, after firing, a ceramic film which can be crumbled or crushed. If the base is not destroyed by firing, the film is cracked and filled with a resin, an electrode stuck on, and the base stripped off. If the base is destroyed by firing, the particles can be dusted on to sheets of foil coated with linseed varnish or a styrene, isobutylene, silicone resin and passed through heated rollers; two such foils pressed together constitute a condenser. The particles may be suspended in a suitable ink for deposition in required areas by a printing process. In another form, a net of paper, textile, or glass fibre is filled with ceramic material and fired. In this form the material can be rolled into a condenser.
