Title: Improvements in cigarette paper
Filed: 1944-10-10
Abstract: 583,149. Cigarette paper. MATTHEWS, R. E., and HARRISON, W. D. Oct. 10, 1944, No. 19510. Convention date, Nov. 25, 1943. [Class 96] The burning rate of cigarette paper, e.g., made from flax fibre and containing calcium carbonate filler, is increased, the tendency of its ash to flake off is reduced, and the wet-strength of the paper increased, e.g., 10 per cent., by impregnation with ammonium sulphate and phosphate, e.g., after the sixth drying roll 11, and heating, ammonia being liberated. 1.57 lbs. of sulphate, 1.26 of mono-, and 0.31 of di-ammonium phosphate may be dissolved in 50 gallons of water for treating 500 lbs. of paper. The solution is pumped at 16 to a trough 13 and applied by a roller 19. Overflow and drainage through a strainer 22 are returned to the supply tank 17.

Vaporizers, external.-Relates to improvements in carburettors of the type described in Specification 129,963, and consists in (1) dispensing with the petrol carburettor and the shut-off cock, (2) providing a three-way cock 10 to admit light or heavy fuel from 11, 12 to the single float chamber g, (3) replacing the screwed needle valve which controls the water supply by a sight feed T within reach of the driver (4) providing return springs 5 to the throttle and air valves 2, 2, and (4) varying the shape of the retort a and vaporizer b. Air enters at i, the nozzle is at f, exhaust gases pass through pipes d, e and the lower of the throttle valves 2 controls secondary air. The throttle and air valve levers 3 are pressed by a spring 5 against a rod 4, the spring being connected to the two levers at different distances from the valve spindles so that as the valves are opened, the spring is stretched and therefore tends to return the valves to closed position. The rod 4 may he adjustable in length to vary the relative positions of the valves.

Filed: 1974-05-06
Abstract: 1460787 Extruding variegated soap COLGATE-PALMOLIVE CO 6 May 1974 19827/74 Heading B5A [Also in Division C5] A plodded striped or marbled soap bar e.g. of rectangular section, Figs. 6 and 7, is produced by injecting a coloured liquid into a stream of the soap during its extrusions at locations disposed transversely of the stream and downstream of the plodder worm, and from which the stream flows through a tapering passage 22 to an extrusion passage of smaller cross-section than the barrel. Radially extending coloured stripes 44 of the same or different colours are produced, but a marbled appearance may also be produced by disrupting the stripes by stationary frames, or baffles, within the tapering passage 22. A soap billet, severed from the extruded bar, may be pressed laterally of the direction of extrusion, or in the direction of extrusion to spread the stripes transversely into a flower like pattern. The liquid, which is preferably insoluble in the soap, is injected into the soap from a plurality of openings 43 provided along the downstream ends of a plurality of hollow radially extending spider arms 29, to which the liquid is delivered from a circumscribing annular spider chamber 42 which may be supplied with the same liquid at a single location 46, or with the same liquid at diametrically opposed locations or with liquids of a different colour at separate segments of the chamber 42 which each delivery to a separate one of the arms 29. The openings 43 may each be provided with a compression spring loaded ball valve, to prevent reverse flow of the soap. The arms 29 have streamlined exteriors, Fig. 4 (not shown). The spider is retained in the extruder barrel 19 between snap rings 26, and has a tubular hub 27 which rotatably receives a stub shaft 28 on the end of the plodder worm 18. The plodder is supplied with the soap at a vacuum chamber inlet, into which the soap is delivered as strands cut a plurality of outlets.

Second conveyers 9 are used to discharge the flowable cargo from the hold.
Patent GB-1538475-A (GB)
Title: Fuse-element for electric fuses
IPC: H01H85/08
Filed: 1976-05-17
Abstract: In the case of the melting conductor it is intended that the fuse be capable of being stressed continuously up to the limit of its rated load capacity without any instabilities occurring in the melting material in this limiting-load region. In the case of relatively high currents in the lower overload region, the fuse is, however, nevertheless intended to be capable of burning through in a short time. In order to achieve this object, the fuse has a plurality of sections (14) of narrowed cross-section. In this case, at least one of these sections (15) is placed on a part along the melting conductor where the operating temperature is in the relatively low temperature range of the operating temperature distribution (17) along the melting conductor, and the cross-section of this section (15) is smaller, but its length is in contrast greater, than in the case of the other sections (14). <IMAGE>

Title: Improvements in or relating to finishing machines for trousers and the like

Filed: 1951-08-30
Abstract: 712,119. Ironing. FORDYCE & CO., Ltd., D. S. Nov. 28, 1952 [Aug. 30. 1951], No. 20523/51. Class 138 (2) A finishing machine for trousers and the like comprises a frusto-conical perforated garmentreceiving head 5 provided with a garment clamp 6, and control means for automatically supplying steam and then heated air for predetermined times to the interior of the head. The clamping plate 6 is pivoted at its centre to levers 7 pivoted at 8 to a bracket 13 secured to a cabinet 2 In operation the waist portion of a pair of trousers, with the upper button thereof secured, is applied over 'the head 5 and the plate 6 lowered by depression of a handle 10 on cam levers 11 pivoted at 12. The cabinet 2 houses an air blower T (Fig. 3) driven by a'motor M. A pipe 3 supplies steam to a steam heated radiator U and to a perforated baffle member N by way of a valve S. Automatic control means. By depressing a foot pedal, a valve A is opened and releases pressure from one side of a piston in a two-way valve B, thus causing air from a supply pipe 4 to pass to the lower end of a cylinder C and by way of a regulator valve D to a pressure vessel L. The piston in cylinder C is moved upwardly to open the steam valve S, thus supplying steam to the head 5. During this time a flap valve 14 of the air blower T has been kept closed due to pressure in the lower end of a cylinder G. When the vessel L is filled with air it operates a valve E which allows release of air from the opposite end of valve B, thus reversing the flow and supplying air to the top of cylinder C and shutting the steam valve S. The time .of steaming can be controlled by means of a screw adjustment on the regulator D. Operation of valve E also releases pressure at one end of a two-way valve F, allowing air to pass to the opposite end of cylinder G, thus opening the flap valve 14 and allowing air to be passed by the blower T over the radiator U into the head 5. Air flows through a regulator valve H into a pressure vessel K and finally operates a valve J which releases pressure at the opposite end of the valve F thus cutting off the supply of heated air to the head 5, and leaving the mechanism ready for a new cycle of operations.

Title: Improvements in or relating to synthetic fibres for blending with natural fibres
IPC: D02J1/22
Filed: 1958-06-26
Abstract: Synthetic filaments which are to be stapled and blended with fibres of lower tenacity (see Group IX) are produced by drawing continuous filaments of a linear condensation polymer capable of existing in a highly oriented and highly crystalline state, e.g. polyamides, such as polyhexamethylene adipamide or polycaproamide, or polyesters, to impart a high degree of orientation thereto, and heating the oriented filaments for a time and at a temperature such that the product of the time in seconds and the temperature in degrees Centigrade is 1000-6000 while maintaining them under a tension which allows them to shrink, if at all, by not more than 4% of their length, so that the orientation is retained.  Stapled fibres are stated to have a load-bearing capacity of at least 2,1 g. per denier at 7% elongation and not more than 6% shrinkage after boiling, both properties being measured after nine days ageing without tension at 78 DEG F. and 72% relative humidity.  In the operation of drawing apparatus, Fig. 1 (not shown), multiple ends of undrawn filaments from a bank of spinning machines or from a creel are combined into a heavy denier, e.g. 63,000, tow, and enter the apparatus as a flat band or ribbon which passes around a series of feed rolls running at the same or different peripheral speeds, thence in a zig-zag path around two or more snubbing pins, over and in contact with an elongated, heated plate, and around a series of draw rolls running at the same or different peripheral speeds in excess of that of the feed rolls.
