Title: Yarns
IPC: D02G3/24
Filed: 1971-04-19
Abstract: 1349680 Forming bulked composite yarns; false-twisting O-B RASMUSSEN 19 April 1971 [3 March 1970 2 April 1970] 27251/71 Headings DID D1F and D1W A yarn comprises a bundle of filamentary structures held to one another by polymeric material that surrounds the bundle at bonding zones spaced along the length of the yarn, the bundle being substantially free of the surrounding polymeric material in the intervening zones between the bonding zones and being in a generally bulky state in the intervening zones. The bundle may consist of a transversely compacted film, each pleat of which constitutes a filamentary structure of the bundle, or it may consist of filaments, staple fibres, fibrillated film, ribbons, non-woven fabrics &c or combinations of these. Fibre mixtures may be used such that heating of the yarn after solidification of the polymer gives rise to differential shrinkage of the fibres between the bonding zones. Alternatively, mixtures of elastomeric and stiffer fibres, monocomponent and crimped bicomponent fibres, or bicomponent fibres of differing crimp may be used. The polymer at each bonding zone may saturate the bundle or, preferably, be bonded to the outermost portion only of the bundle. In apparatus for producing the yarn, untwisted filamentary material 11 is delivered by feed rollers 13, 14, 15 to false twist rollers 16, 17 each of which comprises four outer sections which are reciprocated as the rollers rotate so that a twisting motion is imparted to the filamentary material where it passes tangentially through a semi-circular groove 32 in a roller 25 rotated at a speed corresponding to the linear speed of the material. The polymer is fed from an extruder 26 to radial channels opening at the bottom of the groove 32 whereby rings 24 of polymer are deposited on the filamentary materials. The rings are water cooled between the roller 25 and rollers 16, 17, and the yarn after it leaves pull-rollers 36, 37, may be heated. To avoid squeezing the rings 24 the sections of the rollers 16, 17 may be coated with soft rubber or provided with grooves spaced to correspond with the spacing between the rings. The yarn may be cut between the rings into short lengths for use as filling for pillows &c.

Abstract: 737,674. Filing papers. DEFINAC SYSTEMS, Ltd. Jan. 28, 1954 [Oct. 31, 1952], No. 27386/52. Class 146(1). A posting tray A or trays is or are used in combination with a posting stand B, each tray A comprising a base a and side walls c but no front or rear walls, and a compressing device, for use when the tray is to be stored, such as removable cross-bars g spring-loaded or slotted at f into the sides c of the tray or a pivoted U-shaped member, each tray being adapted to be supported from rails k on the stand B in fixed positions for consultation of the cards contained therein. Each tray A is formed with legs d and the base a is slotted at b to receive lugs on metal dividing and supporting plates h, the outer ones of which, in conjunction with the bars g, hold the papers securely when not in use. Handles e are provided on the trays and they may be formed separately or by folding, as shown in Fig. 1, of the upper of the sides c. The stand B comprises end plates i and the rails k secured to legs m which may be equipped with castors for easy handling. Lugs l are screwed to the rails to leave spaces equal to the length of the handles e which are placed over the rails. Alternatively, recesses may be provided in the rails for locating pins provided on the handles e. Dowels p at each end assist in preventing tilting of the trays. The trays are therefore fixed in position and, with the bars g removed, the cards and supporting plates h are splayed out, the end plates h resting against each other or the end plates i of the stand or against a cross-bar g placed across the rails when there are less than the full number of trays on the stand. Distance pieces h<SP>1</SP> may be provided on these end plates h which abut each other and reduce the angle from the vertical of the plates. Rods n may be provided, which serve to brace the stand and on which trays A may be suspended when not in use. For use on a desk, the stand has shortened legs n and no cross rods n, or a bench may be equipped with the pairs.of rails k.

The body portion 30 may comprise a sleeve 16 which is releasably secured, e.g. by friction, on the portions 12 and 20. Alternatively the sleeve may be formed integrally with the portion 12 (Figs. 7 and 8, not shown). In a further embodiment the filtering and absorbent materials are enclosed between a stem portion and a cigarette receiving portion which are screwed together (Fig. 11, not shown). The stem portion may include a cavity in which is inserted an element 25 comprising a bar 26 provided with short branches 27 to provide a tortuous smoke passage and a tar collection chamber. In use the cigarette receiving portion 12 is immersed in water prior to smoking a cigarette so that the water absorbent material becomes charged with the water.

Abstract: 788,934. Sound reflecting devices. CARLSSON, S. Sept. 27, 1954 [Oct. 2, 1953], No. 27784/54. Class 13. [Also in Group XXXIX] In a sound reproducing system comprising a reflecting plane or two or three reflecting planes at approximately right angles to each other and a sound-reproducing apparatus disposed at one side of said plane or planes, the reproducing apparatus is arranged to radiate low frequency sounds near the plane or planes, and high-frequency sounds markedly more distant and omnidirectionally enough to cause part to be transmitted by way of reflections from the plane or planes. Loud-speaker 1, Fig. 1, which may be placed on the floor, or on a ceiling with legs uppermost, includes a low-frequency loud-speaker in opening 3, a middle frequency loud-speaker 5, and highfrequency loud-speaker 6-9. Opening 4 is the port of the resonator. Loud-speaker, Fig .  3, uses a single loud-speaker mechanism and the whole of the frequency range is radiated via opening 13 and reflector 14.

Abstract: 1,245,575. Inductive or leakage signalling. A. SADLER. 11 Sept., 1968 [16 June, 1967], No. 27868/67. Heading H4U. A portable low-frequency transmitter provided with spaced electrodes is carried by a person and is used to locate the person if buried by snow. The co-operating receiver is provided with an input socket to which initially a 20 metres length of insulated search wire is connected, the receiver being placed on the ground and the wire being arranged radially therefrom over the ground. The wire is then moved around a circular area centred on the receiver until a signal is received. When the signal has maximum intensity the movement of the search wire is stopped and it is disconnected from the receiver and replaced by a lead connected to a metal probe. The rescuer then moves along the deployed search wire inserting the probe in the ground at intervals until a maximum signal is achieved indicating that the buried person is below the probe. As described, the operating frequency is 10KHz and the receiver includes a multivibrator operating at a slightly different frequency whose output beats with the incoming signal to provide an audible tone. It is stated that by the use of a frequency of around 10KHz the transmitter sets up an electrostatic field when buried in snow.

Title: Process for improving the resistance of asphaltic bitumen surfaces
IPC: C08J7/18
Filed: 1960-08-17
Abstract: The solvent, wear, weathering and fire-resistance of an asphaltic bitumen surface are improved by contacting it with a monomer of the formula: R1C(H)=C(R2)X in which R1 and R2 are hydrogen or hydrocarbyl radicals and X is an electronegative radical, or a mixture of such monomers, under exposure to light for a time sufficient to form a film of polymerized monomer grafted to the surface of the bitumen. Monomers specified are acrylamide, methacrylamide, acrylic acid and its methyl and ethyl esters, methyl and monochlormethyl methacrylates, acrylonitrile, acrolein, vinyl acetate and vinyl chloride.  The monomer may be used in the form of an aqueous emulsion or solution.  The bitumen surface to be treated may be that of a body of bitumen or a thin coating of bitumen, as on roofing paper.  The light used to polymerize the monomer may be sunlight or ultra-violet light.  The asphalt is stated to act as a photo-initiator for the graft polymerization.
