Title: A process and a machine for moulding bodies out of plastic material
IPC: C06C7/02
Filed: 1921-11-04
Abstract: 172,287. Grossmann, R. Nov. 27, 1920, [Convention date]. Rolling-machines; cleaning ; delivery; processes. -Relates to the production of bodies from plastic material by feeding the material in plastic form between a pair of oppositely-rotating discs provided with mould cavities, and consists in leading the plastic material in the form of a continuous string between a pair of discs rotating in a horizontal plane. As shown, a pair of discs 1, 2 rotate in opposite directions in peripheral contact and are provided with complementary mould cavities 3. The discs are mounted on shafts 4, 5 carrying intermeshing gears 7, 8 driven through a pinion 10 on a shaft 9 carrying a cord pulley 14. The moulded articles are stripped from the discs by brushes 17, 18 on shafts 15, 16 which are connected by a crossed cord 21 passing around grooved pulleys 19, 20 and are driven from the pulley 14 through a cord 23 and pulley 22 on the shaft 15. To maintain peripheral contact between the discs, the shaft 4 is supported by an eccentrically-mounted bush 24 acted upon by a spring 27 and lever 25.

Abstract: 1,100,998. Masted lift trucks. F. JUNGHEINRICH. 30 June, 1966 [3 July, 1965], No. 29516/66. Heading B8H. The load support of a masted lift truck is movable vertically by an electric motor which is energized and controlled by a pulse control system. As shown, the electric motor drives a winch, the cable 8 of which extends over a pulley 11 on the fixed mast section 5 and passes around pulleys 12, 13 on the movable mast section 6 to an anchorage on the load support 7. The mast assembly is mounted on a carriage 14 which is movable forwardly and rearwardly on the chassis 1. In a second embodiment, Fig. 2 (not shown), the load support is movable on a non-telescopic mast by a screw and nut mechanism driven by an electric motor.

Title: Electro magnetic relay devices

Filed: 1954-10-13
Abstract: 759,723. Electromagnetic relays; electromagnetic interrupters; contact-members for switches. SIGMA INSTRUMENTS, Inc. Oct. 13, 1954 [Oct. 19, 1953]; No. 29539/54. Class 38(5) A relay comprises two non-magnetic frame-members 23 secured to lugs 22 on a base plate 19 and held together by screws 32 to clamp therebetween magnetic yokes 50 and lamination plates 52 and a pair of coils 56. The iron circuit 50, 52 is in two parts separated by a pair of permanent magnets 54 which may be connected at their lower ends by a magnetic piece 55, the magnets 54 being magnetized transversely so that the pair of pole pieces 57 of one part of the iron circuit have one polarity and those of the other part have the opposite polarity, Fig. 3. The armature and contact assembly 14 is secured on the magnet assembly 12 by screws 78 engaging ears 72, 74 of the armature assembly frame 70. A bore 86 in the frame 70 slidably receives a plug 90 having screwed thereon a nut 94 with a conical undersurface supported by the conical upper surface of a split ring 98 which rests on the frame 70. Thus the vertical position of the plug 90 in the bore 86 may be roughly adjusted by turning the nut 94 and be finely adjusted by a screw 101 engaging lugs 102 of the ring 98. The upper end of an armature-supporting spring 114 is clamped against the bottom of a recess 104 in the plug by a bracket 110 held by a screw 112 passing through the bracket and a hob 116 in the spring. The lower end of the spring 114 is clamped by a screw 120 in a slot 82 in a bracket 80 extending from the underside of the frame 70 and lying between the pole pieces 57. The armature 130 is clamped between the legs of a bracket 132 by a screw 136 and passes through a slot 122 in the spring, the bracket being fixed to the spring enlargements 126 by screws 138. The armature ends may lie centrally in the air gaps 53 above the magnets 54 when the coils 56 are not energized, the centralizing force being adjustable by the vertical adjustment of the plug 90, and in such an arrangement the device may function as a resonator, in another arrangement the armature is biased to a side position by turning the plug 90 in the bore 86, for which purpose an arm 144 of the bracket 110 extends through a wider slot 148 in the frame 70 and is engaged on one edge by a spring 150 which biases the arm 144 against an adjusting screw 156. Contacts 142 on the armature end 140 operate between a pair of fixed contact faces 192, each face being formed on a bow-shaped damper spring 186. The spring 186 is integral with spring loops 180 riveted to a part 176 of a screw plug 174, the reverselybent ends of the spring 186 engaging the end face 190 of the part 176 to produce a frictional damping effect without a wiping of the contacts. The plugs 174 are adjustably screwed in opened-sided apertures 172 in plates 164 insulatingly secured to the frame 70. The relay may be hermetically sealed by a cylindrical shell (Fig. 1, not shown) having an insulating lining and secured, to the base plate 19 by pins snapping under spring fingers 28.

Title: Improvements in or relating to magnetic structures and methods of manufacturing same
IPC: H01F1/22
Filed: 1933-10-27
Abstract: 427,639. Inductances. STANDARD TELEPHONES & CABLES, Ltd., BUCKLEY, S. E., and HALLETT, L. W., Connaught House, Aldwych, London. Oct. 27, 1933, No. 29862. [Class 37] Magnetic dust cores, especially for band-pass filters, tuning-circuits, oscillator coils, and coupling coils, after their formation, are coated by surface impregnation with cellulose acetate to increase their mechanical strength by the deposition of a tough film and also to lower their radio-frequency losses. The low-loss dielectric coating serves for efficiently spacing the winding from the core. Polystyrol or a cellulose derivative may be employed for insulating the magnetic particles, while a highgrade varnish, benzyl cellulose, polystyrol or a condensation product of formaldehyde or of urea may be employed for the coating. Iron dust mixed with a solution of phenol-formaldehyde condensation products in alcohol is tumbled to dryness in air and oven-heated, moulded at a pressure exceeding 60 tons per square inch, baked and coated with a solution of cellulose acetate in acetone. Moulding at one ton per square inch may be effected after preliminary heat treatment at about 110‹ C. Magnetic oxides may be used instead of iron dust including such materials as natural magnetite, precipitated ferroso-ferric oxide or hydroxide, ferrous oxide, ferric oxide after heat-treatment with another oxide which is afterwards removed, ferric oxide prepared by decomposing a ferrite, the double oxides of the type Ro.Fe3O3 where Ro represents some other metallic oxide. Alloys such as nickel-iron with insulators such as chromic acid, sodium silicate and talc or clay, sodium silicate and milk of magnesia may be employed. Wax-type insulators such as ceresin, paraffin, superla and chlorinated naphthalene may be employed. The final coating may be produced by dipping the formed core and an initial coating by oxidation or acid treatment may be given.

Abstract: 1,087,233. Circuits employing magnetic storage elements. ENGLISH ELECTRIC COMPUTERS Ltd. July 14, 1966 [July 14, 1965], No. 29903/65. Heading H3B. A plurality of binary words may be separately written and sensed in a single row of a magnetic storage matrix. A column of word locations is defined by series connected column wires which together form a word group such as WG1-1,  WG2-1 and so on. A selected word is read out in column digit lines D1-1, D1-2 . . . D1-n by applying a positive half-current pulse to the associated word group line which is followed by a delayed and overlapping positive halfcurrent pulse in the appropriate row line Y-Y4. For writing a word in a given location, negative half currents are applied simultaneously to a word group line and to a row line Y1-Y4, all the cores in the word group being switched except for those which are simultaneously magnetized by a positive half current inhibit pulse in selected column digit lines D1-1, D1-2, and so on, the digit lines corresponding to the same location in each word group being interconnected. The arrangement may be applied to a three-co-ordinate store, Fig. 4 (not shown). A sense-inhibit circuit is described, Fig. 5 (not shown), in which the digit lines such as D1-1 D2-1 corresponding to the same locations in two different word groups are interconnected through a centretapped transformer (62), the output winding of the transformer being connected to a gated sense amplifier (63). A further transformer (61) connected in the common circuit of the two lines extending from the centre tap provides a coupling from an inhibit source (55) through which inhibit pulses are applied to both lines. The centre-tapped transformer arrangement reduces spurious outputs.
