Filed: 1956-12-28
Abstract: 849,267. Fluid-pressure servomotor control systems. GARRETT CORPORATION. Dec. 28, 1956 [Jan. 6, 1956], No. 39421/56. Class 135. A fluid-pressure regulator comprises a valve controlling fluid flow through a conduit and connected to a movable wall having one side exposed to valve inlet pressure and its other side to atmospheric pressure to open the valve and means including a second valve operable on a predetermined increase in valve outlet pressure to expose said other side to valve outlet pressure and move the first mentioned valve towards closure to regulate the valve opening. As shown, a spring-loaded diaphragm 20 connected to a valve element 27 controlling fluid flow through a conduit 13 divides a housing 16 into upper and lower chambers 17, 18. The chamber 17 is connected to the conduit upstream of the valve through a duct 64 controlled by an electromagnetically operated valve 66 or to the atmosphere through a duct 68 controlled by a second electromagnetically operated valve 67 whilst the chamber 18 is connected to atmosphere through a duct 50 and an orifice 48 controlled by a needle valve 52. The valves 66, 67 aie operated by a single switch 72 so that when the switch is closed the valve 67 is closed and the valve 66 opened to admit inlet pressure to the chamber 17 to fully open the valve element 27. The pressure in the chamber 17 is maintained at a predetermined value by a spring-loaded diaphragm 32 and a ball element 35. The needle valve 52 is formed on the depending stem of a diaphragm-actuated valve 51 the diaphragm 58 of which is urged upwardly by a spring 63 and downwardly by valve outlet pressure. On outlet pressure reaching a predetermined value the valve 51 is unseated and the needle valve 52 closed so that outlet pressure is directed to the chamber 18 which together with a spring 28 opposes the inlet pressure in the chamber 17 to regulate the opening of the valve element 27 and maintain the outlet pressure constant.

Abstract: 1501952 Linear induction motors KRAUSSMAFFEI AG 30 Sept 1975 [3 Oct 1974] 39910/75 Heading H2A A linear induction motor has a primary member 1 at one side of a reaction rail 2, member 1 having a lamination stack 3 with coils 4 extending in slots 8 perpendicular to the motor longitudinal axis and arranged in that surface of stack 3 which face rail 2, and a damping cage formed by damping rods 5 and by longitudinal electrical conductors 6, 7 connected electrically to the rods 5, the slots 8 in their regions adjacent the sides of the primary member 1 being shaped to allow the conductors 6, 7 to be arranged immediately adjacent respective sides of the lamination stack 3 and each at a respective one of the two ends of each rod 5, such ends facing the reaction rail 2. The slots 8 may each have a horizontal central part 8a and linearly rising end parts 8b, 8c, the in-slot coil portions following the slot shape allowing the longitudinal conductors 6, 7 to be located under the lateral coil parts 4b, 4c whereby the consequential reduction in the primary member width B<SP>*</SP> allows the latter width to be less than the reaction rail width A, thereby improving lateral stability, without increasing the reaction rail width. The lamination stack 3 has a lower part 3a formed with the slots 8 and an upper part 3b positioned after insertion of the coils 4, parts 3a, 3b adjoining one another at a plane parallel to rail 2. The invention is applicable to singlesided motors, as shown, or to double-sided motors having a primary member with two halves each as in Fig. 2.

Title: Data-carrier for a time-of-use checking apparatus
IPC: G07F7/00
Filed: 1974-09-16
Abstract: 1446262 Time-of-use checking apparatus SCHULTE-SCHLAGBAUM AG 16 Sept 1974 [17 Sept 1973 24 May 1974] 40249/74 Headings G4V and G4T A date-carrier which is arranged to be coded and read in a time-of-use checking apparatus, the data-carrier comprising a disc provided with a ring of angularly spaced separately magnetizable zones, a zero mark for identifying an angular starting position for successively coding or reading the zones, and a free mark for distinguishing one face of the disc to the other. Numeral 9 denotes a data-carrier coin that can be used in the apparatus, a bathing establishment, of Fig. 1. A user inserts a monetary coin into slot 4. A data-carrier coin 9 is released from hopper 6 into shoot 5 and thence to coding unit 7 and withdrawal tray 8. Unit 7 puts such information as the entry time on to coin 9. The coin is subsequently used in entry lock 10 and deposit lock 12. When a user wants to leave he puts the coin 9 into slot 15 whence it is read by a device 16. The device 16 operates gate 14 possibly with an automatic refund of overpaid money, or an indication is made that more money must be paid before the gate can be opened. Unit 17 is an erasing unit. Coin 9 is of non-magnetizable material, e.g. plastics, having magnetically polarized zones formed by magnetic cores 18 to 25, which can be polarized in unit 7 in a combination representing a particular time. A central core 28 can be polarized to classify the coin, say, for a child or an adult. A supplementary magnetic core 29 is for free-marking the coin. Perforation 30 is used to zero mark the coin, Unit 7 polarizes the cores so that core 29 is always constantly polarized, viz. the same pole is always at the same face of the coin. Reading device 16 receives a pulse from core 29 for correct reading. If a coin is inserted in a turnedover position core 29 switches the reading process so that interrogation takes place in a reverse direction with the polarization of the cores to be read in reverse. The supplementary core could be positioned circumferentially with the other cores and is polarized so that the addition of its North pole to the North poles of the other cores, which lie on the same face of the coin, produces an even number. Face marking could be in a mechanical manner. Figs. 5 and 7 show a coin which during coding and reading is moved relative to a magnetic head. A coin passes through slot 119 and rests on support 120. It is adjacent a rotatable axially fixed thrust bearing 121. Slidable plunger 123 is moved to engage a hole in the coin. This centralizes the coin and lifts it free of support 120 which is moved to one side. During rotation of the coin double-tracked magnetic head 124 produces a coding track C with information I to I 6  on face 9<SP>1</SP> in the form of magnetic fields. An inner timing track T is also formed. The reading station may have two opposed double-tracked magnetic heads to cope with a coin inserted in a reverse position.

Abstract: 1481903 Tyre trimming tool B & J MFG CO 2 Oct 1975 [11 July 1975] 40378/75 Heading B5A A hand held tool for trimming flash from moulded tyres comprises a handle 10 and a steel blade 12 having a cutting edge 14 facing the handle. The handle comprises a rod bent generally to a U-shape and having a grip portion 16 covered by a non-slip PVC jacket and a pair of slotted ends 18 into which the edges 22 of the blade are inserted. The rods are urged into engagement with the blade edges by a slip ring 28 movable along diverging sections 24 of the handle. The blade is longitudinally corrugated and is defined by ridges 40 and webs 48 joined by walls 50. The cutting edge is formed with projections coincident with the ridges 40 and recesses 60 coincident with the webs 48. The underside of each web at the cutting edge of the blade is chamfered to form the bounds of each recess 60 with a sharp cutting edge 62, 64, and the ends of the ridges and walls at the cutting edge are so shaped to form a blunt portion 54 leading through a sloping portion 44, perhaps rectilinear (see Fig. 10, not shown) or curved as shown, to the cutting edge. In a second embodiment a cutting edge is formed at both ends of the blade to render it reversible to extend its life. In a third embodiment (see Fig. 13, not shown), a cutting edge is formed not only on the webs but also on the ridges of each end to give a blade having four cutting edges.

Title: Charge coupled devices
IPC: H01L29/10
Filed: 1975-10-03
Abstract: 1528946 Charge coupled devices PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 3 Oct 1975 [8 Oct 1974] 40572/75 Heading H1K A semi-conductor layer 3 of a bulk CCD has its thickness and doping level chosen so that in use of the device a depletion zone induced by an electric field can be obtained throughout the layer. In operation, layer 3 is isolated from its surroundings so that majority charge carriers transported by a system of capacitively coupled electrodes 10, 11 are confined to layer 3. As shown, isolation is achieved by reverse biasing a P-N junction 4 between a supporting substrate 22 and layer 3 and reverse biasing a P-N junction between a surface zone 5 and layer 3. Charge carriers of opposite sign to the majority carriers are drained during operation by producing inversion regions 19 between regions 13 of opposite conductivity type to layer 3 and zone 5 which lies partially beneath the electrode system 10, 11. Charge may be introduced into the device either by absorption of incident radiation or by introducing electrons into a highly doped zone 7. The charge can be read out from a further contact zone 9. The semi-conductor layer may also be formed on a spinel or sapphire substrate, Fig. 8 (not shown). In a further embodiment the surface regions 13 may project from beyond the edge of the overlying electrodes, Fig. 9 (not shown). The devices of the invention may also be assembled as an orthogonal array to provide a system of coupled shift registers, Figs. 4 to 7 (not shown).

Filed: 1971-09-02
Abstract: 1360047 Purifying gas streams CARRIER CORP 2 Sept 1971 [4 Sept 1970] 41086/71 Heading C1A [Also in Division C7] Oxidizable impurities are removed from a gas by contact with an aqueous acid medium containing an electrolytically regenerable oxidizing agent comprising cobalt, chromium, manganese, cerium or silver in ionic form, thus transferring the impurities to the acid stream and destroying said impurities by action of the oxidizing agent, which results in a decrease in the valence state of the oxidizing agent, and subsequently regenerating the oxidizing agent to the higher valency state by electrolysis of the acid medium containing the agent acid and recycling the regenerated acid stream. The acid medium may be sulphuric or phosphoric acid. Impurities which may be removed include organic compounds containing O, S, N, P or Se, alcohols, ketones, aldehydes, carboxylic acids, amines, ethers, pyridine, sulphur dioxide, hydrogen sulphide, thiocyanates and carbon disulphide. In the electrolytic cell the anode may be of lead dioxide or platinized titanium; and the electrodes may be connected to power lines by resin-coated copper connectors. The electrodes may be of sheet form, grid or mesh; and may be formed by concentric tubes. The waste gas stream may be filtered of solid matter using a mesh screen, electronic precipitator or acid wash. Contact between the oxidizing-agent-containing medium and the waste gas may take place in a packed bed of polypropylene, polyethylene or ceramic packing.

Abstract: 1,004,434. Dish washing machines. F. BEERLI. Nov. 17, 1961 [Nov. 18, 1960], No 41263/61. Heading A4F. In a dish washing machine, washing is by flat sheet-like jets of water emerging under pressure through long slits in a pair of conduit pipes. Dishes are mounted in the tray 29 in the washing chamber 2 and are moved up and down past the jets 13 and 14 by the motor 33 and pulley 32 assembly. Water passes through the rough filter 3 and the fine filter 4 into the pump 7 and thence via the pipe 8 to the conduits 9 and 10 and so to the jets 13, 14 described below. The washer is closed by the lid 35, hinged at 36. Hot or cold water enters through the sprinkler ring 22, which may be used for rinsing, and goes to drain through the valve 27. The machine is heat insulated, and may contain a heater and automatic timing device. Two jets are described. In one, Fig. 6, water flows along the horizontal channel in the upper part of the conduit 11, and then down past the vertical baffles 51 and out through the jetforming gap 6. This gap is formed between the side 41 of the conduit 11 and a rubber or similar strip 38. This strip is bolted to the part 37a of the conduit 11, and is pressed down, to give the required jet width, by the end 46 of the bar 43. This bar is hinged at its ends, 44, and may be rotated by the rod 47 and screw 50 mechanism (with handle 18, Fig. 1). In the other arrangement described, Fig. 7, the jet is formed between the sheet 64 attached to the outside of the conduit 9 and the rubber strip 38. This rubber strip is held between the bar 40 and the side 65 of the conduit 9, and is pressed towards the sheet 64 by the bar 67, to form the jet. This movement is effected by a rod and pivot mechanism, which allows both sets of a pair of jets to be opened together, one jet to be open and one closed, and both jets to be opened fully when the carrier 29 is fully raised, thus washing out the jets. The mechanism is such that the jets are self-adjusting in that the gap for the jet is automatically the same size at each end.

Filed: 1974-10-01
Abstract: 1490722 Luminescent materials and uses thereof GENERAL ELECTRIC CO 1 Oct 1974 [1 Oct 1973] 41269/74 Heading C4S A method of exhibiting phosphorescence comprises marking an object with an alkali metal tungstate phosphor comprising water soluble crystals of formula M 7 EuW 10 O 35 .xH 2 O where M is an alkali metal ion (e.g. Na or K) and x is an integer of 1 to 24, exposing to predominantly 2537 radiation to produce orange red emission. Small stoichiometric deviations such that substantially the same phosphorescence is produced are allowable. A marking ink comprises a liquid dispersion of the phosphor (e.g. in amount 1-5% by wt.) which may be used with a photodetector. The ink may include an adhesive binder system, colourants for immediate visual detection, components to promote bodying, absence of foam and pH control, and reduces abrasion. Detailed examples are included of compositions and rise times. The phosphor may be prepared by boiling ammonium paratungstate in aqueous sodium hydroxide solution to form the Na salt, the pH adjusted (e.g. with acetic acid) to #7, a hot solution of Eu salt at pH of 5-6 added and further heated to produce the phosphor. Significant phosphorescence is not produced under higher wavelength radiation and applications include indicia marking on postal mail, packages, magazines, paper money and cheques, for example. Additional different phosphors may be included for use in photo detection systems which may include more than one radiation source and/or more than one photodetector. Automated systems are discussed including a photodetection sorting system modified to apply the phosphors and additional luminescent materials either sequentially or simultaneously for direction to some other location.
