Title: A selective logical memory apparatus
Inventor: ELLIOTT ANTHONY CHARLES
IPC: B65G47/49
Filed: 1965-05-27
Abstract: 1,101,607. Data storage. M.E.L. EQUIPMENT CO. Ltd. 28 Feb., 1966 [27 May, 1965], No. 22580/65. Heading G4C. [Also in Divisions A4 and B8] A binary memory apparatus includes a main store R and an auxiliary store S, the main store having a first input into which information may be written from outside and a second input into which information may be written from the auxiliary store, and having a first output from which information may be read-out and a second output from which information may be transferred to the auxiliary store, in which each store comprises a plurality of sections into which information is written and further includes two movable markers, a tail marker 22, 23 arranged to mark the section of the store into which the information is next to be written and a head marker 21, 24 arranged to mark the section of the store from which information is next to be read out, the markers being arranged to circulate successively through the store as information is written in or read out of the memory apparatus. The memory is associated with a conveyer belt (1, Fig. 1, not shown) carrying articles to a loading point (8). As the articles pass a photo-electric cell (11) data concerning them is entered into the cell in store R determined by the tail marker 22 and the tail marker is moved to indicate the next storage space. The articles are moved towards the loading station until they pass a second photoelectric cell (13). If the article is to be loaded, then it passes to the station and its data is removed from the memory. If it is not to be loaded (if for instance a van is conveying articles to a specific shop and the present article is intended for a different shop) then it is transferred to a feed-back conveyer (14) and its data is taken from memory R via the head marker 21 and read into the S store via the tail marker 23. When the articles on the feed-back loop pass a third photo-electric cell (16) they are entered on to the main conveyer belt and their data is taken from memory S via head marker 24 and entered into memory R via tail marker 22. An operator (9) controls the entry of articles from the feed-back loop to avoid collisions.

Title: Operation of rail car couplings
IPC: B61G7/04
Filed: 1975-05-23
Abstract: 1477590 Operating rail car couplings SOUTHERN PACIFIC TRANSPORTATION CO 23 May 1975 [16 Aug 1974] 22796/75 Heading B7T Apparatus 10, Fig. 4, for ensuring that the pivoted knuckle 3 of a coupling 1 is substantially fully open prior to a coupling operation, comprises an arm 21 which carries an electromagnet 23 and which is supported on a baseplate 11 for pivotal movement about vertical and horizontal axes. The arm 21 is normally stored in a lowered out-of-use position in which it rests on a cradle 31, Fig. 7, but when an oncoming rail car passes between a light source 38 and a photo-electric cell 39, a motor 15, Fig. 7, and solenoid 33 are actuated and the arm 21 slides along a guide bar 28 to an upright position. An electromagnetic coil 23a of the electro-magnet 23 is energized and the electromagnet 23 engages the knuckle of the oncoming rail car. The rail car carries the electro-magnet 23 with it and causes the arm 21 to slide along the guide bar 28 such that the electromagnet 23 pivots about a vertical axis and moves laterally away from the centre of the rail track. The electro-magnet 23 finally slides off the coupling knuckle and the arm 21 is returned to its lowered out-of-use position. The solenoid 33 may be replaced by an hydraulic cylinder. Instead of using the above-described photo-electric system to detect an oncoming rail car, a switch 52, Fig. 9, actuated by a wheel 51 of a rail car, may be utilized. The electro-magnet 23 may be replaced by a permanent magnet.

Aug. 15, 1932, No. 22866. Convention date, Aug. 15, 1931. [Classes 39 (i) and 40 (iii).] In a television, picture - telegraph, or like receiver, a cathode-ray tube 1, Fig. 2, is provided with a luminescent screen 5 maintained at a high potential relatively to the cathode 7, coils 33 or plates deflecting the ray to explore the screen 5, and, between the coils 33 and the cathode 7, a ray-focussing and modulating electrode 17 and an apertured accelerating anode 11. The electrode 17 varies the area of the anode 11 on which the ray is focussed and so the intensity of the ray passing through the aperture 13. This modulating action may be supplemented by a control grid 10 varying the number of electrons in the original ray. The electrodes 10, 17 are biassed negatively and positively, and are connected to a resistance or transformer circuit 25 forming a push-pull signal input so that they operate cumulatively. The anode 11 may comprise also a tube 15 with further diaphragms 12, 14. A coating 29 inside the tube 1 is connected to the screen 5. Particular voltages of the electrodes are specified. In a modification, the anode 11 is a single apertured diaphragm extending across the tube 1 and having a tubular extension, and a space-charge electrode or anode is mounted between the electrodes 7, 17, the grid 10 being omitted. In another arrangement, Fig. 3, the electrode 17 is replaced by an electrode 39 at a fixed positive bias focussing the electrons on the aperture 13 and modulation is effected by an electrode 38 robbing a varying number of electrons from the ray. The electrode 38 is so biassed positively that the tube operates on a steep negativelysloped part of the curve connecting the current to the screen 5 with the voltage on the electrode 38. The Specification as open to inspection under Sect. 91 comprises also the replacement of the electrode 17 by a solenoid coaxial with the ray. This subject-matter does not appear in the Specification as accepted.

Title: Improvements relating to metal vapour valves
IPC: H02M7/51
Filed: 1931-08-17
Abstract: 383,667. Converting. AKT.-GES. BROWN, BOVERI, ET CIE, Baden, Switzerland. Aug. 17, 1931, No. 23159. Convention date, Sept. 2, 1930. [Class 38 (ii).] The reserve conductors for continuous current power transmission are utilized as condensers with or without initial voltage to extinguish the arcs of metal vapour valves which serve the purpose of converting continuous into alternating three-phase current. In Fig. 1, 1, 11 are the main and 2, 12 the reserve conductors and the valve 4 with its cathode 5 feeds the outgoing three-phase network 6 through the transformer 3. The reserve conductors are connected through the switch 8 to the casing of the valve from which the cathode 5 is insulated, and may also be connected through the resistance 10 and battery 9 to the cathode side of the valve. The capacity between the reserve conductors and the cathode which is connected to earth is represented by the condenser 7. Upon occurrence of overload in the threephase network the switch 8 is automatically closed and the potential of the casing becomes lower than the potential of the cathode. This results in transference of the arc for sufficient time to allow the cathode to cool and the working arc is interrupted. In the absence of a battery 9, similar conditions occur, since, owing to the lack of potential difference between the casing and the cathode, the are is transferred to the casing and charges up the condenser 7 so that the arc is interrupted. In Fig. 2 (not shown) an auxiliary valve acts as a switch for disconnecting the continuous current conductors, the arc being extinguished in fundamentally the same manner as in Fig. 1.

Abstract: 822,107. Photo-electric systems. DU PONT DE NEMOURS & CO., E.I. July 23, 1957 [July 26, 1956], No. 23297/57. Class 40 (3). [Also in Group XXXVI] A device for producing mechanical movement in accordance with incident electromagnetic radiation consists of a condenser with one movable plate and one plate transparent to the said radiation, a steady potential being applied between the plates and the dielectric material between the plates being such that its permittivity varies with variation of the incident radiation. The Fig. 1 embodiment shows a fixed conductive layer 3 of tin oxide mounted on a transparent rigid place 2, and adjacent to layer 4 which contains photo-dielectric particles dispersed in a light-transparent dielectric medium. A partially movable resilient plate 5 co-operates with the layer 3 to form a condenser across which a potential is applied from a suitable D.C. source 9. Changes in the electrostatic forces between plates 3 and 5 due to changes of the dielectric constant of layer 4 cause the plate 5 to move. In Fig. 2 (not shown), the movable plate 5 is mounted on a flexible diaphragm and the voltage applied across the plates is from a generator and may be A.C. If a D.C. potential is applied and if the incident light has an audio-frequency modulation an audible sound is produced. If the frequency of the said A.C. voltage is in the audio range the output of the device will be intensity modulated sound. The photo-electric substances may be, for example, zinc sulphide or cadmium sulphide and the dielectric medium (and also the transparent plate 2) may be any of such substances as beeswax polystyrene, polymethyl methacrylate, ethylcellulose cellulose nitrate, or plasticised polyvinyl chloride.
