Title: Garment strap material and method of making the same
IPC: A41F15/00
Filed: 1969-10-13
Abstract: 1,236,504. Straps. C. M. OFFRAY & SON Inc. 13 Oct., 1969 [25 Oct., 1968], No. 50203/69. Heading A3V. [Also in Division D1] A strap material comprises a fabric web (10) folded inwards from both sides so that the parallel side marginal edges (13), (14) are in opposed relation to each other, preferably abutting at the centre of the strap, an adhesive 21 securing the two layers thus formed together, and a flocked layer 25 which is attached by the adhesive so as to conceal the marginal edges, while preferably not covering the whole width of the strap. The method of making the strap material comprises advancing a web of porous fabric substrate material and folding it to form a double layer at the folding station (11) before the adhesive is applied at the adhesive station (20). The flocked layer is then applied at the flocking station (24), the adhesive then being cured to bind the two fabric layers and the flocked layer at the drying station (26).

Abstract: 1,132,447. Travelling-band filter. AMERICAN AIR FILTER CO. Inc. 26 Nov., 1965 [21 Jan., 1965], No. 50391/65. Heading BIT. In a travelling band filter in which a filter web of glass fibre is wound progressively across a fluid duct from a supply roll to a take-up roll, the chambers 3, 6 housing the said rolls are provided each with a plurality of roll-insertion/removal doors 31 and with web-feeler members adapted to bear on the rolls. The feeler member 18 in the supply chamber 3 (Fig. 2 not shown) is biassed by a spring (28) to engage the roll 7 and operates switch (16), at a predetermined amount of web remaining on the roll, to give an alarm and stop the web take-up motor 9 (Fig. 4, not shown). Spring (28) and the pivot mounting of feeler 18 are such that, with front door 31 wide open, feeler 18 may be moved out until spring (28) urges it on to the door, away from the web. A similar arrangement applies to web hold down bar (36) (Figs. 5, 6, not shown) in take-up chamber 6. The glass fibre is wound on the rolls in a compressed state, but expands while in the duct, and bar (36) serves to recompress the web before it is wound on to the take-up roll. The chambers may have a front, rear and side door each, and the rolls are wound on spools (Fig. 3, not shown) whose ends engage slots 17.

Abstract: 1334553 Motor driven mechanical switches HELMUT BALZ GmbH 3 Nov 1971 [19 May 1971] 51025/71 Heading H1N Power-operated positioning apparatus, particularly for mechanical valve control, comprises a housing 1 with a spindle 4 therein connected to a member 2 (such as the valve) to be controlled. A motor 8 drives the spindle 4 through gears 7, 6 and the threaded end 5 of the spindle screws into a threaded hole 3 in the member 3 to move it rectilinearly. When the member engages an abutment such as the stop 2<SP>1</SP>, the spindle in continuing to turn moves axially so that a ring 15 on the spindle 4 moves a bearing 13, which is slidable in a cup 17, to frictionally engage a sleeve 24 between inner bearing parts 13a, 12a. The sleeve 24 rotates with the bearing parts and cams 25, 260 thereon operate one set of microswitches 26, 28 or 27, 29 to interrupt the motor circuit. When moving in the other direction the member 2 can engage a stop (not shown) so that a ring 14 moves the bearing 12 to frictionally clamp the sleeve 24 which then operates the other set of microswitches 27, 29 or 26, 28. The bearings 12, 13 are biased apart by a U-shaped spring 270 having bifurcated ends engaging the bearing parts 12b, 13b. The cams are arranged for sequential operation of the micro-switches.

In a weighing machine the output voltage, e.g. 0.7654 V from the weigh balance 2 (Fig. 1) is first fed via amplifier 14, the gain of which is set at 1 to an analogue/digital converter with display units 18-21, the most significant digit 7 of the displayed signal being used to manually position selector switches 10, 28. The switch 10 sweeps a tapped potentiometer 4 so that a voltage 0.0654 V representing the weight less the most significant digit is fed via amplifier 14, the gain of which is set to 10, to the analogue/digital converter, the three next most significant digits then being displayed on units 18-20. The most significant digit is displayed on unit 24 under the control of switch 28. The least significant digit display unit 21 is cut out by a relay R opening contact r2, the relay also changing over via relay contact r1 the gain of the amplifier. The analogue/digital converter used only needs a resolution capacity of one-tenth that of the balance 2. By including an additional unit 24 and an amplifier with a gain of 1 and 100, an analogue/digital converter of one-hundredth the resolution capacity of the balance may be used.

The inner and outer surfaces of a pressure vessel 7 and a nut 12 are formed with helical grooves 15, 16 positioned opposite each other to define a helical passage in which is disposed a hollow resilient member 17. The width of a clearance space which is provided between the outer peripheries of the member and the surfaces of the grooves decreases progressively along the length of the member in the direction of an applied load tending to move the nut axially with respect to the vessel. The nut presses a thrust washer 13 on to an enlarged portion 10 of the cover 9. The pitch diameter of the grooves in the nut or vessel may progressively increase in the direction of the applied load, or the cross-section of the member 17 may progressively increase in the direction of the applied load, or the grooved surface of the nut or the vessel, or both, may respectively increase or decrease in diameter in the direction of the applied load. The member 17 may be in the form of several springs, segments of tubes, or members which are C-shaped in cross-section and strung on a wire or rod which extends along the helical path formed by the grooves.

Abstract: 1,205,405. Oxirane compounds. HALCON INTERNATIONAL Inc. 20 Nov., 1967 [23 Nov., 1966], No. 52591/67. Heading C2C. Oxirane compounds are prepared by catalytically reacting an olefin with an organic hydroperoxide to form a by-product alcohol, at least part of the catalyst being removed from the reactor effluent before the by-product alcohol is recovered from the effluent. The catalyst is preferably removed by treating the effluent with a basic material, e.g. a hydroxide, carbonate, bicarbonate or oxide of an alkali or alkaline earth metal or a basic organic compound, which may be used in the presence of water. The olefin used as starting material may carry a substituent, e.g. a hydroxy group, an ether group, a carboxy ester group, a ketonic group or a halogen. It may, for example, be an oil or a polyolefin. Preferred catalysts are the naphthenates and carbonyls of molybdenum, titanium, tungsten, vanadium rhenium, niobium, tantalum, selenium, chromium, zirconium, tellurium and uranium. Examples are given of the oxidation of propylene with ethylbenzene hydroperoxide to give propylene oxide and α-phenyl ethanol.

Abstract: 1,200,305. Compression moulding. W. R. GRACE & CO. 23 Nov., 1967 [24 Nov., 1966], No. 52738/66. Heading B5A. [Also in Division B6] A method of shaping thermoplastic material includes the step of pressing an ultrasonicallyvibrated tool against the material to soften it, the material being simultaneously shaped by the tool itself or by a subsequent compression step using the tool itself or a non-vibrated, preferably cooled, tool. Articles may be moulded from blanks by this method or the surface configuration of already existing articles modified. In the embodiment, illustrated in the Figure, a blank to be shaped is moved upwardly into co-operation with a stationary ultrasonically vibrated shaping tool 29, 30, by a platform 32 actuated by a piston 34. The tool is vibrated through a velocity transformer 27 by means of a magnetostrictive or piezo-electric device 26 located in a cooling bath 23, and may be itself cooled by a conduit 30. In an alternative embodiment (see Fig. 2, not shown) a blank is located in a crown cap and is compressed to a liner by a reciprocable upper vibrated tool. The above method and apparatus is particularly useful with thermoplastic polymers such as butyl rubber, an ethylene-vinyl acetate copolymer, low density polyethylene or a mixture of these. Alternatively plasticized P.V.C., rigid P.V.C. or polymethyl-methacrylate may be used.
