Filed: 1962-02-23
Abstract: 946,264. Goodyear welt seam construction. V. A. SHERBROOK. Feb. 23, 1962, No. 7164/62. Heading A3B. A shoe construction embodying a goodyear welt seam comprises a welt strip 16 secured to a separate tape sewing rib 12 on the insole 10 and folded over the rib and cemented to the inner part and to the insole, the welt strip completely covering the rib. The upper 14 is connected to the welting by stitching 18. The welt strip is elongated and of considerable width and may be provided in substantially continuous strips of rubber type material or plastic. It is preferably provided with an elongated fabric stripping as at 20, provided with an elongated gutter 22 simplifying the folding over operation. The outsole is cemented to the welt and insole and the bottom cavity is considerably smaller than the conventional cavity, so that a bottom filler is not essential. The welt may have a decorative bead 30 and may be given a decorative rounded look and a flatter surface to which the outsole adheres by laying a cord 60 around the seam before the welt strip is wrapped around over the rib and insole (Fig 8).

Title: Improvements in the production of polyurethanes
IPC: C08L75/00
Filed: 1953-03-19
Abstract: Cross-linked polyurethanes are obtained by reacting bis-chlorocarbonic acid esters and diamines and including in the reaction mix one or more tri- or tetra-functional chlorocarbonic acid esters or amines in such amount that for each functional group forming part of a difunctional reactant there is from 0.005 to 0.1, preferably from 0.01 to 0.05 of a functional group forming part of a tri- or tetra-functional reactant.  Examples of such higher functional compounds are bis-a -amino-ethylamine, g -aminopropyl-o -aminohexylamine, a  - aminoethyl - e  - amino pentylamine, diethylene triamine, bis-N.N1-g -aminopropyl-hexamethylene diamine, N.N1-bis-g  - aminopropyl - para - phenylenediamine and the chlorocarbonic acid esters of glycerine, trimethylolpropane, 1.2.4 - butanetriol, 1.3.5-hexanetriol and pentaerythritol.

Title: Improved Patterning Mechanism for Knitting Machines.
Inventor: WIDDOWSON ALBERT HENRY
IPC: D04B15/66
Filed: 1968-02-16
Abstract: 1,187,911. Knitting-machines. WILDT MELLOR BROMLEY Ltd. 21 Jan., 1969 [16 Feb., 1968], No. 7657/68. Heading D1C. [Also in Division H1] In a circular or twin bed machine having needles or associated jacks bearing pattern butts, the butts are selected electromagnetically by means including selectors held in operative or inoperatives by mutual attraction of a permanent magnet and electromagnetic or electromagnetically influenced means. Each needle jack 17 comprises a spring extension 17c normally flexed outwards so that a lower butt 18 lies in the path of a raise cam 26. Pressers 19 fulcrumed in front of each jack force the butts 18 inwards prior to each selection where they are held by a magnet 30. The upper ends of selected pressers are now urged inwards as they pass the pattern unit, so that the butts 18 spring outwards. The pattern unit comprises a bank of selectors 35 pivoted to swing axially or tangentially relative to the needle cylinder. As shown an extension 35c of the selector forms the core of an electromagnet 38', pulsed by means of a pattern, and is thereby attracted by either one pole or the other of a permanent magnet 39. The electromagnet may be single or double wound, or comprises two axially spaced magnets. In a modification the extension 35c comprises a permanent magnet the far pole of which is selectively attractable by poles of an electromagnet. In one embodiment in which the selector moves tangentially an electromagnet fixed to it is attracted by permanent magnets on either side of it. In a modification the selector comprises the electromagnet core The pattern comprises a photoelectrically scanned punched tape having as many columns as feeds, and groups of rows in which each row corresponds to selectors disposed at a particular height. "Routing" pulses are provided by photoelectrically scanned holes (46a Fig. 7 not shown) in an axial extension of one of the tape drive rollers. The electromagnet is thus influenced either by the coincidence of pattern and routing pulses, or routing pulses only.

Title: Improvements in or relating to cooling systems for intermittently acting absorption refrigerating apparatus
IPC: F25B17/08
Filed: 1933-03-14
Abstract: 409,493. Refrigerating. ELECTROLUX, Ltd., 153, Regent Street, London.- (Assignees of Platen-Munters Refrigerating System Aktiebolag ; 2, Norrmalmstorg, Stockholm.) March 14, 1933, No. 7718. Convention date, March 14, 1932. [Class 29.] Absorption systems.-Intermittent cooling of the generator-absorber 10 or other heatdelivering member of a reversing absorption refrigerating system is effected by an auxiliary liquid or condensing- evaporating circulation system having two limbs, one of which is heated while the refrigerating system is in the generating phase so as to interrupt the circulation of the cooling-liquid. The cooling- liquid system shown in Fig. 1, comprises a jacket 15 within the insulation 22 of the generator-absorber, a riser conduit 16 leading to an air-cooled element 17, and a limb 19, 20 with a seal 21. During the generating phase, heat is imparted to a coil 19 of the limb 19, 20 from a continuation 13 of the flue 12 of the generator, and the weights of the liquid columns being equalized, the circulation ceases. When the heating of the flue is discontinued, the heat of absorption produces a flow in a clockwise direction. The liquid in this system may be paraffin oil or ethylene glycol. In the cooling system shown in Fig. 2, a volatile medium such as benzene or pentane is used, and the downflow limb includes a collecting vessel 26, a pressure vessel 28 and an overflow vessel 30, with connecting-pipes 27, 29, 31. The conduit 14 for vapours expelled from the generator is formed into a coil 33 around the pressure vessel to supply heat thereto during the generating phase. This creates a vapour pressure in the vessel and forces liquid up the pipe 27 and down the pipe 29, and the liquid supply to the vessel 30 is interrupted. The pipe 32 from the vessel 30 is formed as a smallbore coil 23 around the generator-absorber, and in this coil a gas-bubble pump effect may be produced to lift the liquid to the air-cooled condenser element 24 of the cooling-system. Preferably the refrigerating condenser 34 is air-cooled by the same cooling-flanges 17 as the condenser 24, since the condensers are only effective alternately. In modifications, the pressure vessel 28 is replaced by a coiled conduit, or the liquid is returned to the conduit 16 from the supply vessel 26 through a U-tube or a pumping coil adapted to be heated in the generating phase. The insulation for the generator may consist of reflecting aluminium foil. The Specification as open to inspection under Sect. 91, mentions the application of the cooling system to other apparatus in which intermittent cooling is required. This subject-matter does not appear in the Specification as accepted.

Abstract: 696,604. Radiation pyrometers. LEEDS & NORTHRUP CO. April 6, 1951 [April 7, 1950], No. 8068/51. Class 40 (iii). A radiation pyrometer is fitted with an optical system comprising a first optical system for producing an image of an area of the body whose temperature is to be determined, and a second optical element for redirecting energy from a sharply defined proportion of this optical image on to a radiation sensitive detector. In one embodiment, the radiant energy from a small area of a wall passes through an annular opening 13 (Figs. 2, 3) in a diaphragm 14, and is reflected by a concave mirror 11 to focus at S<SP>1</SP> on the rear of 14, covered with magnesium oxide to prevent dispersion. A window 11a in the mirror 11 allows for visual focal adjustment by screwing the mirror holder 19 in the air-tight housing 18. Energy from a small area s<SP>1</SP> of the image passes through an opening 14a in the diaphragm 14 to fall on another concave mirror 16, which focusses the radiant energy from s<SP>1</SP> on the target area 20 of a detector 17. The opening 14a may be of any desired shape, e.g. circular, rectangular, triangular, &c. In a modification the diaphragm 14 is formed as a rim to the secondary mirror 16.
