Title: Production of cigarette filters
IPC: C08J9/30
Filed: 1966-03-23
Abstract: 1,145,484. Tobacco smoke filters. CELANESE CORP. 23 March, 1966 [29 March, 1965], No. 12743/66. Heading A2C. [Also in Division D2] Cigarette filter tips are made by using a gas to foam an aqueous slurry of cellulose fibres containing a surfactant and a vinyl acetate polymer emulsion, draining liquid from the foam to form a porous sponge the pores in which are coated with a vinyl acetate polymer film, then wrapping the sponge with paper to hold it in the form of a rod having a density of not greater than 0.14 g/cc. The sponge may be initially cast into a sheet which is then sliced into strips to be compressed into the rods, or the sponge can be formed directly into a rod shape. The gas may be air, carbon dioxide or nitrogen. The drained foam may be heated to increase the size of the cells in the sponge. The fibres may be natural or man-made cellulose fibres. The surfactant may be sodium lauryl sulphate containing free lauryl alcohol, long chain sulphonic acids, long chain alkybenzensulphonic acids, long chain alkanol-amides and long chain quaternary ammonium compounds. The polymer may be vinyl acetate homopolymer or copolymers of vinyl acetate and dibutyl fumarate, ethyl acrylate, methyl methacrylate, vinyl alcohol or dibutyl maleate. The amount of polymer in the dry sponge can be 10-20% wt. of the cellulose present. The filters may also contain charcoal ferric oxide, triacetin polyethylene glycol, triethyl aceate, dimethyl phthalate and dioctyl phthalate.

Abstract: 858,973. Capacitors. LONDON ELECTRICAL MANUFACTURING CO. Ltd. April 23, 1959 [April 23, 1958], No. 12894/58. Class 37 A capacitor is made by cutting along line 16 of a stack (Fig. 1) consisting of dielectric layers 11, 14, 15 and metal foil layers 12, 13 forming the electrode the latter projecting from opposite sides of the stack as shown. The stack is then treated to effect adherence between the layers by heating and pressing, a thermoplastic adhesive being first used to coat the layers if necessary. Alternatively, (Fig. 2) the electrodes may be formed as metallised areas 18 19 on a mica plate 17 between mica plates 20, 21 each of said areas extending round one edge of the plate as shown. The stack is heated and pressed as before. More than one metallised plate may be used (Fig. 3, not shown). A machine for making a stack as shown in Fig. 1 is shown in Fig. 4. Dielectric tapes 27, 28, 29 and wider metal foil tapes 30, 31 displaced in opposite directions from the dielectric tapes are interleaved and brought together to pass between heated rolls 32, 33 which heats and presses them. The dielectric tapes may for example be of orientated polystyrene which will adhere to the metal tapes when heated or either the metal or dielectric tapes may be coated with a thermoplastic adhesive. The capacitors are cut from the stack by a cutting wheel 36 entering a slot 35 in a reciprocating guide block 34, a grinding wheel 37 grinding the cut edge to adjust the capacitors. Wheels 36, 37 are supported as a block 38 which reciprocates with block 34. The Provisional Specifications refers to silver paint as forming the metallised areas on the mica sheets and to a cylindrical capacitor formed by winding the interleaved tapes on a core of plastic tape.

Abstract: 894,157. Magneto-strictive devices. PHILIPS ELECTRICAL INDUSTRIES Ltd. April 17, 1959 [April 22, 1958], No. 13176/59. Class 40 (4). The windings 5, 6 of magneto-strictive transducer elements 7, 8 mounted beneath a vessel 9 are energized by a polarizing alternating current Io of mains frequency and by an ultrasonic frequency current I modulated at the same mains frequency, the polarizing current Io leading in phase on the modulated current I so as to improve the efficiency. As shown, the mains frequency current source is connected to transformers 3 and 12 which provide modulating and polarizing outputs respectively, the modulating output being applied to the output stage 1 of an oscillator-amplifier 2. The leading phase angle of the polarizing current may be of the order 10 to 20 degrees, and is established by using either a choke 14 in the primary circuit of transformer 3 or by a capacitor (represented by dash-lines) in the primary circuit of transformer 12. Alternatively, a coil or capacitor may be connected in the secondary circuit of the respective transformer, or both components may be employed together.
Patent GB-131841-A (GB)
IPC: B25B23/10
Abstract: 131,841. Russell, F. W. Sept. 16, 1918. Screws, inserting.- Screwdrivers for power operation are fitted with a screw-supporting device comprising a sleeve slidable on the spindle and carrying pivoted jaws which are normally locked in position to support the shank of the screw during driving and are automatically unlocked when the screw is nearly home. The screw-supporting device may be constructed as described in Specification 131,761 in which the jaws are pivoted to a spring-controlled slide on a sleeve on the spindle and locked by engagement with the end of the sleeve, or by a. cone on the sleeve engaging their rear ends, until released by relative displacement of the slide on the sleeve due to the head of the screw when nearly home acting on the jaws. In a modification. Fig. 3, the jaws 32 are slotted to engage the pivots 33 carried by the sleeve 30, and locked by a coned part 37 engaging the rear ends of the jaws until the screw is driven in sufficiently far for the head to carry forward the jaws, against the action of springs 34, 35, so that they clear the part 37. In a further modification, the jaws are pivoted to a spring-controlled slide on the sleeve and exterior shouldered faces are engaged and locked in position by pins on the sleeve until the screw head causes their descent, wlien the shoulders pass clear of the pins to release the jaws. In another modification, Fig. 5, the jaws 48 pivoted to the sleeve at 49<1> are held locked by a cone 45 on the screwdriver spindle until the upper end of the cone passes clear of the jaw ends as the screw is driven in, or the cone may be formed on a spring-controlled sleeve which is depressed to release the jaws by a collar fixed on the spindle. The sleeve is held against rotation by bearings which permit of the necessary longitudinal movement for release of the jaws.

Abstract: 1450028 S.T.O.L. aircraft HAWKER SIDDELEY AVIATION Ltd 5 May 1972 [5 May 1971] 13247/71 Heading B7G An aircraft with STOL capability has propulsion engines 11 mounted below the level of, and formed of, the wings 10 so as to discharge their effluxes into the forward ends of diffusers 19 which are slung under the wings 10, and in which the engine effluxes are mixed with cooling ambient air entering the diffusers 19 around the engine nozzles 13, the diffusers 19 in turn discharging their effluxes toward the undersides of slotted wing flaps 18. The diffusers 19 are in the form of augmentor boxes that can, at least in part, be folded or retracted for conventional flight. In one embodiment, the side walls of the augmentor boxes are formed by fixed vertical walls 15 of aerofoil section to give minimum drag in conventional flight, while the upper wall of each box is the undersurface of the wing 10. The bottom walls 16 are in the form of doors which, for conventional flight, are retracted into the vertical walls 15. When the doors are lowered for the STOL flight mode each first drops vertically, as indicated at 24, and then swings inward and upward while its outer or hinge end continues to drop, in a path that avoids the door entering the jet efflux. The augmented and cooled exhaust mixture issuing from the rear end of the augmenter boxes is diffused over the span of the slotted flap system and a substantial percentage of the impinging flow is deflected downwards, as at 20, to give a vertical lift component. A smaller percentage of the flow is directed through the slots 21, 22 and over the flap upper surfaces to induce a further lift component. In an alternative embodiment (Figs. 6 to 8, not shown),-the top wall of each augmenter box is formed by a movable element that retracts upwardly into the underside of the wing.
