Abstract: 869,210. Combined mechanical and magnetic filtration. SOMMERMEYER, H. July 17, 1959 [Dec. 12, 1958], No. 24684/59. Class 46. [Also in Group XXVIII] Liquid to be filtered enters at 1, Fig. 1, a chamber 2, whence it passes through a slot 3 into the region between a housing 4 and a jacket of filter material 6 in which closelyspaced needles 7 are embedded. The jacket 6 surrounds one or more magnets 5, and the needles project on the outside of the jacket and lie inductively against the magnet 5 on the inside. A suction effect is created by the shape of the outlet slot 3<SP>1</SP>. The apparatus may be disposed in a suction or pressure pipe of a liquid circuit. In Fig. 3 (not shown), the magnet 5 is in the form of a flat plate and the jacket 6 is arranged above it ; no housing is shown. In Fig. 4 (not shown), spaced layers of filter material or felt, without needles, are arranged above a flat plate magnet. Fig. 5 shows a plurality of such filters arranged in parallel. In Fig. 6, (not shown), steel shavings rest on a flat plate magnet. In Fig. 7 a filter belt 6 provided with needles 7 moves in a counterclockwise manner around a flat plate magnet 8. Liquid to be filtered flows from left to right (or transversely of the belt) and impurities are blown, sucked, rinsed, brushed or shaken off the belt 6 in the region of one of the rollers 10. In Fig. 8 (not shown) the plate 8 is omitted and one of the rollers 10 is replaced by a rotating cylindrical magnet. The material 6<SP>1</SP> may be synthetic plastic, e.g. cellulose acetate butyrate. When such materials are used an electrostatic filtering effect also is produced.

Title: Improvements in or relating to electrical counting apparatus

IPC: H03K21/08
Filed: 1952-10-02
Abstract: 743,528. Frequency measuring. CINEMATELEVISION, Ltd. Oct. 2, 1953 [Oct. 2,1952], No. 24693/52. Class 37. In each counting period a pulse counter circuit delivers a voltage proportional to the number of pulses counted into an output meter and the latter always exhibits the count iast made, i.e. zeroizing the counter does not zeroize the meter. In Fig. 1 a gate 2 opened by timer 7 allows pulses from source 1 to be counted in counter 3 and displayed on meter 6 via switch 4 and capacitor 5. The detail of 4, 5 and 6 is shown in Fig. 2 as comprising three cathode followers 8, 12, 16 and at the end of a counting period timer 7 closes gate 2 and momentarily operates relay 10 so that cathode load 9 charges proportionately capacitor 11. The timer 7 then resets counter 3 and opens gate 2 so that a fresh count commences but capacitor 11 feeds into valve 12 and cathode load 13 therefore holds the previous count voltage and co-operating meter 14 continues to display the previous count. The sensitivity and zero of meter 14 can be adjusted by resistor 15 and potentiometer 18 respectively. If meter 14 is centre zero the cathode potential of valve 16 is adjusted by potentiometer 18 so that cathode of valve 12 takes a potential midway between potentials reached by the cathode of valve 12 for counts of 0 and 9. In a second embodiment, Fig. 3, for measuring frequencies up to 1 megacycle/sec. (at terminal 24) six decade units 25- 30 at the end of 10 second periods respond to operating of relay 31 and deliver their count voltages simultaneously to actuate indicators 38-43 through storage capacitors 32-37. The 10 second timer comprises a six decade counter 21 fed from a 100 kc./sec. supply 20 and feeding a pulse at 10 second intervals into a control unit 22 which opens gate 23 and then closes gate 23 when operating six-contact relay 31. When the latter reverts the timer counter 21 and measuring counter 25-30 are reset to zero and gate 23 again opens whilst meters 38-43 continue to indicate the frequency in the previous 10 seconds. The counting periods may be one second or less. The switch means as at 4 in Fig. 1 may be designed for selective manual operation so that an indication of the total count recorded at any desired instant may be obtained. Also additional switching means may be provided whereby the storage capacitor S may be removed from circuit so that a continuous indication of the count is obtained.

Class 120(2) A cross-winding machine in which the number of cross-overs is reduced periodically solely by varying the rate of rotation of the package spindle 8, is provided.with a spindle drive comprising side-by-side trains of gears each train consisting of three wheels 18, 31, 9; 19, 32, 10; 20, 33, 11; 21, 34, 12; 22, 35, 13; 23, 36, 14; the first two of each train being in constant mesh, and being mounted in a common carrier 25, 28, preferably weighted at 37, for simultaneous movement so that one pair after another they come into mesh with the third wheel of their respective trains, the duration of their in-mesh position representing the time of winding between the one change in the number of cross-overs and the next. The wheels 18...23 are keyed to a driving shaft 7 driven by an electric motor 3 through V-belts 16a and a double grooved pulley 16, 17. As the package grows in size, the traverse cam box 6 actuates a lever 43 to remove a stop 44 thereon from engagement with one after the other of stops 39 positioned at different radial distances from the axis of rotation of the carrier 25, 28 to permit the carrier to move to bring into mesh the next gear train. Lubricating guides 30b are provided for the gear trains. The carrier may be re-set after completion of a wind by a treadle-operated rod 42 and chain 41. An oil dash-pot system is connected to the cam box 6 and thread layer 47a, the operation of a valve releasing the oil, after completion of a wind, to permit the thread layer 47a to fall back into contact with a new package to be wound.

Abstract: 1519493 Radiation curing of coatings ENERGY SCIENCES INC 10 June 1975 [9 Dec 1974] 24822/75 Heading B2E [Also in Divisions B5 and Dl]  A process for electron-beam curing of a coating comprises passing the coated substrate along a predetermined path, directing electron strip beam radiation through an electronpermeable window at a preselected region of the path with the radiation extending linearly along the path, accelerating the radiation in a direction substantially perpendicular to the path, adjusting the radiation within energy limits of from 50 to 30 KeV and with doses of 0.5-8 megarads in dependence of the thickness and materials of the coating and substrate so that a maximum amount of electron beam energy is concentrated in the coating to cure the coating, with minimum beam energy concentration in the substrate. The method may be used to apply a pressuresensitive adhesive to paper, vinyl, vinylasbestos, cork, wood, cotton, polystyrene, nylon, urethane film and leather. The method is also particularly suitable for application of coatings to strand-like substrates such as wires, cables, filaments, strings, yarns and threads. A reflector may be positioned behind the substrate to reflect the radiation back onto the coated substrate. In an embodiment the coating is first applied to release sheet, cured by radiation, a tie coat is applied to the first coat and the substrate applied to the tie coat.

A double-drive hammer comprises a reciprocable main frame 1 carrying a first die 9 and providing a differential cylinder 2 containing an operating ram 5 carrying a second die 6 and a free piston 7 subjected on one side A to liquid pressure and on the opposite side B to air pressure. The main frame 1 is reciprocable vertically in guides 3, 4. High-pressure liquid is supplied through passage 12 to the space A between the ram 5 and piston 7 to raise the ram and the frame 1 into their upper positions as determined by bolts 20. Compressed air from one of several air cylinders operating at different pressures, is then supplied through passage 13 and passage 22 into space C to hold up the frame 1 whilst the liquid is partially drained from space A to permit the ram 5 to fall against a key 23. To perform a working stroke the air is released from space C whereby housing 1 falls by gravity until radial ports 14 communicate with space B. The compressed air thus acts below piston 7 to move it upwardly and also to accelerate the downward movement of the frame 1. Liquid trapped in space A thus causes the ram 5 also to move upwardly. Towards the end of the working stroke, annular projections 16, 17 on the ram and piston co-operate to cushion the movement and reverse the motion of the piston 7 before impact occurs.
