Title: Improvements relating to elastic fabrics and elastic gores for boots and other apparel or the like
IPC: A43C11/00
Filed: 1937-10-06
Abstract: 503,525. Elastic fabrics for shoe gores &c. DAWES, R. T. Oct. 6, 1937, No. 27081. [Class 142 (iv)] [Also in Group VII] The fabric has elastic strands grouped in greater numbers (shed together) near one or both edges than at and near the centre, so that the margin or margins of the gore offer greater resistance to stretch than the body thereof. Thus the fabric may have groups of two elastic strands 10, Figs. 9 and 10, and one stuffer warp thread at one edge and groups of one elastic 8 and two stuffer warps 26 elsewhere interwoven with parallel sets of weft threads 24, 25, which also interweave with warp threads 27, so that the edge of the fabric serving as the upper edge 7, Fig. 2, of the gore, which is most stretched in use, is more elastic than other parts of the inserted gore. The elastic strands are equally spaced and the fabric is of uniform thickness throughout. The gore may comprise such elastic fabric covered whilst stretched with leather &c. previously scored with parallel lines cemented to the face and also over the free edge 7b, Fig. 6, of the fabric. By arranging the elastic yarns in groups of varying numbers the elasticity may be made to vary progressively from the body portion to a selvage, or as shown in Fig. 16, towards both selvages. The latter fabric may be covered at 65, 66, 67 with leather and be used for gores 58, Fig. 15, having two free margins, or it may be cut as shown in Fig. 18, to form two independent gores. Various forms of gores are referred to. The numbers of warp threads between the grouped elastic threads may vary. Cotton, silk, artificial silk, or wool stuffer warp threads may be used.

Title: A new or improved warning system and/or apparatus for use with automobiles
IPC: B60Q1/50
Filed: 1934-09-20
Abstract: 444,580. Press - button retractive switches. WALKER, F. P., 125, Eyre Court, Finchley Road, London. Sept. 20, 1934, Nos. 27092/34 and 8134/35. [Class 38 (v)] [See also Group XXXVIII] Warning circuits are arranged on a vehicle so that a two position press-button switch controls in its two positions a soft and a loud audible warning, or a visible and an audible warning, the signals controlled in the two positions being determined by a selector switch which may comprise part of the pressbutton switch. The selector and press-button switches may be combined with the vehicle light. control switch. The visible warning may comprise either lighting or dipping the headlamps. As shown in Figs.' 1, 3, 4, 5 (Comp.), the top 2 of the switch is rotatable so that the portions P and Q respectively control the soft horn H1 and the loud horn H2, as shown in Fig. 4 (Comp.), or the headlamps L and dipping mechanism L1 and the two horns H1 and H2, as shown in Fig. 5 (Comp.). If the switch is in the position shown in Fig. 4 (Comp.), when the top 2 is depressed the raised portion P is first effective to sound the horn H1, resistance to movement being provided by spring S1. If the top is still further depressed additional resistance is supplied by spring S2 and the portion Q becomes effective to complete the loud horn circuit. With the switch turned into the positions shown in Fig. 5 (Comp.) the first depression lights and dips the headlamps and the second sounds both horns. Figs. 1 (Prov.), and 2 (Prov.), show a switch for controlling the vehicle lamps as well as providing the circuits of the invention. The switch can be rotated to any one of the positions D, N1, N2 and N3 and in positions N1, N2 and N3 the contact disc 22 which is fixed to the top 2 by studs (not shown), operates the side and tail lamps, the side, tail and head lamps and the side, tail and head lamps and the dipping mechanism respectively. The top 2 is depressed for signalling, contact rings in the base 1 being of varying heights so that in the first depressed position, when the resistance is supplied by spring 20 and surface 14 is stopped by spring plate 21, either the soft horn, the head lights or the dipping mechanism is effective whilst when the top is pressed down further against the resistance of spring 21, brush 29<1> contacts with ring 9<1> to sound the loud audible signal. As shown, when the switch is in position N3, the headlamps are normally dipped and the first depression position is ineffective but an additional high level contact ring could be arranged in this position so that the first depression operates a relay to cut out either headlamps or dipper.

Title: The preparation of a biodegradable detergent
IPC: C07C2/30
Filed: 1961-07-27
Abstract: Hydrocarbons of formula <FORM:0936882/III/1> wherein Ar is an aromatic hydrocarbon group of which the nucleus is directly linked to the quaternary carbon atom, R is predominantly straight-chain C3-6 alkyl and R1 is predominantly straight-chain C5-8 alkyl, are produced by dimerizing in presence of an aluminium alkyl catalyst one or more C5-8 predominantly straight-chain alpha-olefins containing on their non-ethylenic carbon atoms on the average less than 0,5 equivalent side-chain methyl groups and alkylating an aromatic hydrocarbon (e.g. benzene or toluene) with the dimers.  The C5-8 olefin feed stocks may be obtained from (a) low severity steam cracking of wax, petrolatum or a paraffinic gas oil, (b) liquid phase thermal cracking of a paraffinic feed stock at 800 DEG -1000 DEG F., (c) high conversion steam cracking of gas oils at 1250 DEG -1500 DEG F. or (d) an ethylene growth process in presence of aluminium alkyls.  The preferred catalyst for dimerization is an aluminium trialkyl (e.g. triisobutyl) but a dialkyl aluminium chloride is also mentioned; additional catalysts such as nickel, cobalt, palladium and platinum may be used, particularly where it is desired to isomerise internally double bonded olefins in the feed stock.  Preferred catalysts for the alkylation step are AlCl3, HF, BF3, AlBr3, polyphosphoric acid, H2SO4 and aluminium chloride hydrocarbon complexes. In the example, dimerization of hexene-1 with Al(n-hexyl)3 gave a C12 olefin containing 82% 2-n-butyl-octene-1, which was used to alkylate benzene in presence of AlCl3 to give the corresponding dodecylbenzene. Specification 770,310 is referred to.ALSO:The invention comprises biodegradable detergent compounds of formula <FORM:0936882/IV(a)/1> wherein Ar is an aromatic hydrocarbon group of which the nucleus is directly linked to the quaternary carbon atom, R is a predominantly straight-chain C3-6 alkyl group, R1 is a predominantly straight-chain C5-8 alkyl group and X is a nuclear-attached sulphonic acid group or water soluble salt thereof.  The extent of branching R and R1 is such that on the average less than 1,0 (preferably less than 0,6) equivalent methyl groups, in addition to the two terminal methyl groups, is present.  Such compounds are produced by dimerising in presence of an aluminium alkyl catalyst one or more C5-8 predominantly straight-chain alpha-olefins containing on their non-ethylenic carbon atoms on the average less than 0,5 equivalent side-chain methyl groups, alkylating an aromatic hydrocarbon with dimers and sulphonating the alkylated aromatic hydrocarbon.  The preferred product is the sodium sulphonate of 2-phenyl-2-n-butyloctane.  Specification 770,310 is referred to.

Title: Improvements connected with photographic apparatus
IPC: G03B17/53
Filed: 1928-09-22
Abstract: 323,199. Hana, G. H. Sept. 22, 1928. Automatic and coin-freed apparatus; cameras with connected action between s h u t t e r and changing- mechanism.-A camera for taking a series of photographs on a strip of roll film comprises (1) a spindle 15 driven by a handle 14 or by a motor and carrying a cam 16; (2) levers 18 and 19 actuated by the cam 16 and operating electric lighting and counting mechanism respectively; (3) coin-freed or other mechanism for locking the cam 16; (4) a spoked wheel 38 geared to the spindle 15 and operating a lens shutter, film changing mechanism, and a knife for severing the exposed strip of film. On placing a coin in the shoot 24, Fig. 1, the locking lever 17 is overbalanced and its notched end 21 lifted clear of the cam 16. When the spindle 15 is turned, the cam 16, acting on the nose 21a, gives the lever 17 a further movement, so that the coin reaches a wider part of the shoot and slips past the pin 22. The movement of the cam 16 also releases the lever 18, which then moves under the tension of the spring 28 and operates the lighting switch 31. The spindle 15 carries a bevelled wheel 34 adapted to drive the shaft 36 of the spoked wheel 38. The first spoke operates a shutter lever 41a, and immediately afterwards engages a spoke on a further spoked wheel 39 to which a film sprocket wheel is attached, the film being thus moved to bring a fresh section before the camera lens 65. At this stage the plunger 64 on the handle 14 enters the first of a series of eight holes 63, and the attendant can then request the sitter to change his position. The wheel 39 has eight equally spaced spokes, and the wheel 38 has ten holes in its circumference into eight of which spokes are fitted, leaving two holes next to each other. Further rotation of the spindle 15 causes a series of eight exposures to be completed. The wheel 38 having then reached such a position that the treble space is opposite the shutter lever 41<a> and wheel 39, its rotation causes a wiper 51 to actuate the lever 52 and knife 55 for cutting off the exposed strip, which is removed and developed by the attendant in the light-proof chamber 69. 'The cam 16, having now returned to its original position, lifts the levers 18 and 19, thus switching off the light 68 and operating, through the cable 32, the counting mechanism 33, which is so placed as to be photographed with the sitter, and is finally locked by the coin-freed mechanism.

IPC: H01L49/02
Filed: 1963-07-10
Abstract: 1,083,575. Resistors; capacitors. MARCONI CO. Ltd. April 28, 1964 [July 10, 1963], No. 27325/63. Headings H1M and H1S. A microminiaturized circuit module of the kind wherein a circuit component, e.g. a resistor or a capacitor electrode, is constituted by a thin film of a conductive material, e.g. nickelchromium alloy, deposited on an insulating substrate, e.g. glass or ceramic, has at least a portion of the thin film deposited on the outer corrugated surface of a layer of insulating material deposited on the substrate. By " corrugated surface" is meant any surface shape which departs materially from the smooth. As shown in Fig. 2, a layer 4 of insulating material, preferably silicon monoxide, is deposited on the substrate 1, the upper surface of the layer 4 having a pattern of corrugations 5. Upon these corrugations, a thin film 6 of nickelchromium alloy is deposited to form a resistor. If a capacitor is required, a thin layer of insulat. ing material is deposited on the thin film 6 and a second layer of conductive material on the insulating layer. A capacitor with both electrodes corrugated is thus obtained. The use of a corrugated surface provides a substantial increase of effective area for the deposition of conductive material from a substrate of given dimensions, and consequently a greater range of resistance or capacitance values is possible.

Abstract: 640,291. Cathode-ray tubes. GENERAL ELECTRIC CO., Ltd., and MOORE, R. C. Oct. 13, 1947, No. 27419. [Class 39 (i)] An electrode or electrode system is supported from a cylindrical wall part of a cathode-ray tube by projections 2, 4, Fig. 1, lying in two different transverse planes, and by a resilient metal strip 6 engaging the wall between the projections, the arrangement being such that when the strip 6 engages the wall it forces the projections 2, 4 against the tube wall. In Fig. 1 the electrode 1 is a hollow metal cylinder with annular flanges 3, 5 to each of which are attached two metal discs 2, 4, each pair of discs being spaced apart by about a third of the periphery of cylinder 1. After insertion the electrode 1 is fixed in position by fusing the glass wall to strip 6 or by fusing low melting- point glass between the glass wall and strip 6. The arrangement allows for exact electrode alignment even though the envelope crosssection is not truly circular, e.g. is elliptical. Two electrodes spaced apart may both be supported in this manner with their projections aligned. In a modification, Fig. 3 (not shown) the pairs of projections 2, 4 are each replaced by a single projection. In a further modification, Fig. 4 (not shown), the discs 2, 4 are replaced by two members which extend along the electrode cylinder between the two transverse planes. In all forms the projections and/or the resilient metal strip may be formed integrally with the electrode or may be separate members fixed thereto. The cylindrical electrode 1 forms part of an electrostatic lens. The Provisional Specification describes a form similar to Fig. 1 but in which the projections are secured directly to the electrode cylinder wall.
