Title: Improvements in and relating to vehicles for transporting goods
IPC: B61B1/00
Filed: 1930-02-10
Abstract: 348,186. Transferable containers for loading vehicles. CAREY, W. L. DE M., 52, Norfolk Square, London. Feb. 10, 1930, No. 4405. [Class 78 (iv).] A transporting system comprises one or more low trolleys adapted to run longitudinally above a power driven vehicle, either on the surface of the vehicle or else on fixed rails running either side of it, the driver of the vehicle being provided with controls for adjusting the positions of the trolleys. As shown, the trolleys run on rails r disposed longitudinally on the vehicle f, and are provided with transverse rails b adapted to be brought into alignment with fixed rails g carrying the wheeled containers k<1> which are to be transferred to the trolleys. Each trolley is brought into position by an endless rope driven by the engine through a clutch mechanism or otherwise, and the exact alignment of the rails b, g is effected by a pivoted latch h, carried by the trolley and controlled by a spring h<1>, which rides over one of the wedges i, Fig. 5, which are mounted beneath the track g, and engages the slot i<1> between them. The latch h simultaneously strikes a pivoted catch and disengages it from a pin k on the wheeled container k<1>, thereby allowing it to pass by gravity on to the trolley. The latch h is pivotally mounted in a frame u which slides within a spring frame t, and is automatically drawn out of engagement with the wedge i by means of a rope u<1> connected to a lever u<2> operated by the container k<1>. The latch h normally hangs clear of engagement with the wedges i, but is brought into the engaging position by elevating the sprung bell crank v by means of a wire o. Mechanism similar to that described may be provided at the other end of the trolleys for unloading purposes, the latch h‹ being mounted in a frame similar to t which moves laterally with respect to the trolley against the action of springs when the latch is brought to rest, the relative movement causing a projection on the latch to trip a pivoted catch m and allow the container k<1> to move off the trolley.

Abstract: 495,853. Expanding-pulley belt gearing. ORTMANS, E. Feb. 15, 1937, Nos. 4510 and 4511. Void. Convention dates, Feb. 14, 1936 and Aug. 18, 1936. Addition to 453,330. [Classes 80 (i) and 80 (ii)] A threaded control-shaft 46, which is turned by a handle 51 to cause axial movement of thrust-sleeves 21, 44 for simultaneously expanding one set of V-grooved pulleys and contracting another coacting set, acts on the thrust-sleeves in either direction through springs 69, 70 which are of such strength that they do not yield when the control shaft is turned during running, but which yield to the greater resistance if the control shaft is turned whilst the gear is stationary. In the latter case, the actual adjustment of the pulleys will be effected by the particular stressed spring 69 or 70 as soon as the gear is started. The springs 69, 70 are arranged between an axially movable block 45 fast to the thrustsleeves 21, 44, and a nut 67 mounted on the screw-thread of the control-shaft 46 and prevented from rotation by a feather 68. The springs abut on washers 71 so as to act singly in either direction. Single or double grooved pulleys may be used, and the driving and driven shafts may be parallel, or, as shown, a countershaft 28 is employed. A driving pulley a has fast halves 3, 4, feathered to the internal driving shaft 1, and movable halves 5, 6 secured together by spacer bolts 7 and bearing in the thrust-sleeve 21 through taper-roller bearings. The fast and movable halves 14, 15 and 11, 12 of a coaxial final driven pulley d are similarly connected respectively to a final driven sleeve 16 and the thrust-sleeve 21. The pulleys a, d are connected by pairs of trapezoidal belts with countershaft pulleys b, c respectively, the movable halves 33, 34 and 37, 38 of which are carried in ball-bearings in the thrust-sleeve 44. The gearing is enclosed in a casing, and is cooled by air sucked in at a central opening 86, Fig. 2, and expelled at one or other outer openings 87, 88 by centrifugal force and the movement of the belts. Several gears may be arranged in series and be controlled by a single threaded shaft. The application to planing and milling machines, air-compressors, fans, blowers, printing and cigarette-making machines, and spinning and twisting spindles and fliers, is referred to.

Title: Improvements in or relating to the manufacture of mouthpiece cigarettes
IPC: A24C5/52
Filed: 1953-02-19
Abstract: 741,175. Cigarette-making machines. MOLINS, D. W., and MOLINS MACHINE CO., Ltd. Feb. 1, 1954 [Feb. 19, 1953; March 30, 1953], Nos. 4734/53 and 8738/53. Class 130. In the formation of a composite filler consisting of alternate tobacco portions and stubs for the production of mouthpiece cigarettes by a continuous rod process, a tobacco stream is passed through an enclosed passage at the outlet of which it is cut at intervals, the outlet being blocked after each cutting operation so as to hold up the uncut stream to allow the cut length to move away on a conveyer moving at substantially the same speed as the tobacco stream to form a gap into which a stub is inserted. In Fig. 1 the tobacco stream is carried by a tape 1, over which a steel band 3 runs at higher speed, into a passage 7 the upper wall of which is formed by the band 3 and the interior walls of which are all highly polished. At the outlet of the passage 7 the stream is periodically cut by a rotating sector knife 10, Fig. 2, the cut length being carried forward by a cigarette paper band 12 while the uncut stream is blocked by the knife so that a gap is formed into which a stub is inserted and correctly positioned by the devices 15, 24, described in Specification 709,197. In a modification, Fig. 3, the tobacco stream passes through a passage 105 with highly polished walls and is cut by a vertically reciprocating flexible knife 108 which flexes as it moves down over the sloping outlet of the passage 105, whereby the cutting edge of the knife is given a forward movement in its cutting stroke substantially equal to the distance travelled by the stream during cutting to obtain a straight cut. The knife 108 is actuated by a cam so that it blocks the outlet of the passage 105 to allow the formation of a gap into which a stub is inserted by the mechanism of Fig. 1. Specifications 646,746, 709,203 and 709,260 are referred to.

Title: An improved method for the production of sheets and boards
IPC: B29C70/50
Filed: 1944-03-15
Abstract: 587,191. Compound fibrous sheet materials. GATES, W. E. F., and' IMPERIAL CHEMICAL INDUSTRIES, Ltd. March 15, 1944, No. 4795. [Classes 96 and 140] [Also in Groups V, XI, and XXIII] Laminated material is made by feeding an assembly of superimposed synthetic resin-containing sheets 8 between a portion of the total length of each of two continuous metal bands 1, said portions travelling in substantially the same direction and at the same speed, the assembly being heated by a high frequency electric field applied from the metal bands, and being subjected to pressure applied to the surfaces of the metal bands remote from the material being laminated. The pressure may be applied to the bands by sets of rollers 9, by means of stationary pressure shoes, or by means of two series of track elements which move in the same direction and at the same speed on either side of the two metal bands, each track element presenting a flat face to the metal band with which it is in contact, and pressure being applied to the metal bands through the track elements by means of rollers acting against the side of the track elements remote from the bands. The members which apply pressure to the bands are made from, or supported by, electrically insulating material such as phenolformaldehyde laminated material or polythene, and similar insulation is necessary for the rollers 2, 3, 4, and 5 carrying the metal bands. Connection of the bands 1 to the high frequency generator is by metal rollers 3 and 5 and conductors 6 and 7. The bands may be smooth or figured to produce corresponding surfaces on the laminated material. Thin sheets of thermoplastic synthetic resin may be welded to form thick sheets, e.g.; thick sheets of polyvinyl resins for shoe soles, which may be reinforced with sheets of fibrous material, or thick sheets of polymethyl methacrylate for optical purposes. Sheets of fibrous material such as paper, wood, fabrics, and asbestos may be united using synthetic resin adhesive applied as an impregnation, coating, or interposed sheets. Wood veneers may be united by phenolformaldehyde resin, and fibrous sheets such as asbestos paper or cloth by dispersions of polyvinyl resins in a non-solvent plasticizer or in water. Light boards for heat and sound insulation are made from superposed layers of comminuted fibrous material such, as cotton flock, linters, clippings or segments, or asbestos wool, which are impregnated with or contain a resin such as phenol-formaldehyde, or polyvinyl resin dispersion. The boards may be'simultaneously or subsequently coated with wood veneer or synthetic resin. Fillers, plasticizers, pigments, or dyes may be added to the synthetic resins used. Specifications 500,298 and 554,176, [Group XI], are referred to.
