Title: Improvements in or relating to lifts
IPC: B66B17/12
Filed: 1945-04-27
Abstract: 590,976. Lifts. EXPRESS LIFT CO., Ltd., and DIXIE, W. A. April 27,1945, No. 10654. [Class 78(ii)] The cage of a lift has means for the ready attachment to its under side of one or more weights, so that the amount the counterweight exceeds the weight of the' empty cage can be reduced and the lift thereby adapted for faster running on light loads. As shown, the weight 4 normally rests on supports 16 at the foot of the liftshaft, and can be picked up by the cage 1 by bringing it below the lowest level served and into contact with stop buffers 20. In this position, a fixed cam 24 depresses a rod 21 on the cage to unlock a trap-door 19 giving access to a control lever 10 by which pivoted stirrup members 7, 8 are rocked to engage bosses 17 on the weight. 'One or more further weights may be disposed alongside the weight 4 to be simultaneously picked up by further pairs of stirrups similar to 7 and 8 and connected for operation with them. The speed of the lift is automatically controlled according to whether or not the weights are attached. For this purpose the control lever 10 carries an apertured plate 34 controlling movement of spring actuated plungers 31, 39 having cams 35, 36 and 42, 43 for actuating low and high speed switches 37, 38 and 44, 45 alternatively. In Fig. 5, the lever 10 is positioned for disengaging the weight, and an aperture in the plate 10 registers with plunger 31 which is moved by its spring /32 to release cams 35 and 36 from switches 37, 38 which accordingly close the circuit for low-speed running. In the other position of the lever, in which the stirrups are engaged with the weight, plunger 31 is retracted to break the low-speed circuit and plunger 42 operated to close switches 44, 45 for the high-speed drive. In intermediate positions of the lever, both switches are open and the lift cannot operate. The control circuit is also broken by a switch 29 when the trapdoor 19 is open.

Title: A method of coating minute, liquid-containing polymeric capsules
IPC: C08L81/00
Filed: 1967-03-08
Abstract: 1,141,300. Microcapsules. NATIONAL CASH REGISTER CO. 8 March, 1967 [4 April, 1966], No. 10913/67. Heading B8C. [Also in Division B2] Liquid-containing capsules having walls of hardened polymeric material are coated by preparing a slurry of the capsules in a liquid in which the capsule wall-material is swellable but not soluble, adding to the slurry a finely divided solid particulate material which is insoluble in the liquid of the slurry, draining the free liquid from the slurry causing the solid particulate material to deposit on and around the swollen capsules, and drying the mass of capsules by evaporation of the residual liquid to shrink the capsule walls which thereby partially entrap the adherent solid particulate material. The capsules are prepared from a liquid dispersion of the capsule wall forming and nucleus materials. The capsules may contain a curable liquid resin e.g. a polysulphide resin, and the solid particulate material may be a curing agent for the resin e.g. at least one of manganese dioxide, tellurium dioxide, antimony trioxide and lead dioxide. In Example 1 the capsules are prepared from a liquid dispersion of acid-extracted pig skin gelatine and gum arabic as capsule wall-forming material and liquid polysulphide resin as nucleus material hardened with glutaraldehyde, and manganese dioxide is added to a slurry of the capsules in water. In example 2 the capsules contain a liquid viz. toluene which does not co-react with the applied material viz. magnesium silicate.

Patent GB-637185-A (GB)
Title: Improvements in the production of pre-stressed reinforced concrete sleepers and similar beams
IPC: B28B23/06
Filed: 1947-04-24
Abstract: Moulds for concrete sleepers or similar beams, which may have slotted removable end plates, as described in Specification 572,387, are successively assembled around reinforcing wires stretched above each of one or more production lines, which may be low brick or concrete walls, and slid along the lines either on a track, e.g., a roller track, or on the reinforcing wires until the lines are full.  As each mould arrives at its position it is supported if necessary on wedges or adjustable feet.  After tensioning the wires the moulds are filled with concrete from a hopper or bucket carried by an overhead travelling crane having a transverse bridge which extends across all the lines.  During and/or after filling each mould is vibrated by an electrical or mechanical vibrator manually applied to the mould. After hardening, which may be accelerated by the process described in Specification 602,024, the wires between the moulds are cut and the crane used to remove the sleepers, with or without the moulds. The last mould is then hauled along each line to stretch new lengths of wires above the lines, the wires running off reels on vertical shafts at one end of the production lines.  When the moulds are slid along the wires the end plates have to be closed before moving the moulds and the moulds and end plates may have wheels, hooks or the like to engage the wires and facilitate the movement.  Specifications 572,385 and 572,390 also are referred to.

Title: Data storage
Inventor: CHAIMOWICZ JEAN CLAUDE ADAM
IPC: G03G19/00
Filed: 1960-03-29
Abstract: 995,234. Ferromagnetic devices. RANK XEROX Ltd. June 28, 1961 [March 29, 1960], No. 11053/60. Heading H3B. [Also in Division H1] A data storage device comprises means to apply a potential across a photo-conductive layer on a layer of ferro-electric or ferromagnetic material and means for positioning a spot of radiation on the photo-conductive layer to effect storage within an elemental area of the ferro-electric or ferromagnetic material. In Fig. 2, a transparent ferro-electric layer 6 consisting of triglycene sulphate lies between a transparent conducting stannic oxide film 4 and a photo-conductive layer 2. A conducting plate 3 and glass plate 5 support the assembly. A given elemental area of layer 2 may be rendered conductive by a narrow beamed light pulse so that a part of ferro-electric layer 6 may be polarized by a potential applied between electrodes 3 and 4. The stored charge can be read by applying a " reading pulse " of opposite polarity in conjunction with a light pulse the material then reverting to its initial state. A ferromagnetic film may be used in place of the ferro-electric layer, and current passing through the elemental area in response to the application of a light spot and a potential, results in magnetization of an annular region around the elemental area. Destructive reading out is accomplished as for ferro-electric material. To restrict the cross-sectional area of the current region, an additional film of anistropic resistivity, or an elongated form of electrode 3 may be provided, or electrode 3 may be made of aluminium with a sputtered gold annulus encircling the whole area which results in the balancing out of lateral currents.

Title: High frequency electric synchroscope
IPC: G01R25/00
Filed: 1931-04-15
Abstract: 377,211. Wireless transmitting systems. COMMUNICATION PATENTS, Inc., 60, Broadway, New York, U.S.A. April 15, 1931, No. 11139. Convention date, July 25, 1930. [Classes 39 (i) and 40 (v).] Phase synchronism between two high-frequency sources of the same frequency is determined by generating light waves from each source, causing said light waves to interfere, and detecting such interference. In the arrangement shown, lines 12, 13 (which may be replaced by directional antennµ systems of any well known type) transmit the carrier frequencies of two broadcasting stations A, B, which operate on the same frequency and are to be maintained in phase synchronism, to transformers 14, 15 connected through amplifiers 16, 17 to a neon tube 20, provided with two anodes 24, 25 and with a single cathode. The light rays from the anodes are projected through a triangular prismatic lens 28 and superimposed on a semitransparent medium 29. The light passing through the latter is reflected back from a mirror 33 having such a curvature that alternate dark and light areas are produced on the medium 29 by the interference of the reflected and transmitted light from either source. The elements of this interfering light system are so adjusted that the light areas produced from one source are superposed on the dark areas of the other when the impulses producing the light rays are in phase, thereby producing uniform illumination on the medium 29. Any fluctuations of light intensity produced by phase displacement between the sources are detected by a photo-electric cell 35, the output of which is amplified at 37 and transmitted to an intensity meter 38 calibrated to indicate the phase shift. By locating the synchroscope at one station, the frequency at this station may be automatically adjusted, by temperature variation of a crystal or magnetically, by means controlled by the photoelectric cell, in order to maintain it in phase with the frequency at the other station. Specification 367,915 is referred to.
