Title: Centrifugal coin sorter
IPC: G07D3/02
Filed: 1973-11-08
Abstract: 1425359 Sorting and counting coins UNIVERSAL MACHINE CO Inc 8 Nov 1973 [20 Nov 1972] 51787/73 Heading G4X In a centrifugal coin sorter, coins of random denomination are deposited in bulk through a hopper 26 on to the central portion 16 of a rotatably driven disc assembly, an outer annular portion 38 of which has sorting means for arresting the outward movement of coins under centrifugal force at different radial positions depending on the coin denomination. In the embodiment described, the sorting means comprise radial, tapered channels 46 cut in the underside of the annular disc portion 38 which revolves with the central portion 16 above a stationary table assembly 4, 60. A sector of the table has apertures at different radial and angular positions to receive coins of different denominations and transmit them through shoots 110 into receptacles 112. A stationary cam 70 lifts coins over a barrier ring 50 and is located with respect to the sector of the table 4 having the coin shoot apertures (78) (Fig. 2, not shown) so that only one coin is directed into a channel 46 per revolution of the disc. Coins are deflected from the channels 46 by fingers 82 and are counted by a photo-cell when a light beam is interrupted. Each aperture (78) has two coin receptacles with means for directing coins to one or the other as the count reaches a desired number (Fig. 5, not shown). Coins are prevented from piling up on each other by a shear ring 30 and weighted rods 130 adjacent the barrier 50 which allow a single layer only to reach it. The cam 70 is lowered by an eccentric cam arrangement 75, 76 when the speed of rotation is not high enough for coins to reach their correct position in a channel 46 before the channel crosses the appropriate table aperture (78) for that coin, e.g. during starting and stopping.

Abstract: 1,171,970. Separating olefins. IMPERIAL CHEMICAL INDUSTRIES Ltd. 28 Oct., 1968 [15 Nov., 1967], No. 51949/67. Heading C5E. Mixtures of branched and unbranched olefins are separated by contact with a disproportionation catalyst to effect oligomerization of the branched olefin, the oligomer then being separated. At least some of the unbranched olefin may be disproportionated. Suitable catalysts are oxides of Re, Mo and W supported on Al 2 O 3 , SiO 2  and/or MgO; preferred is a mixture of CoO and MoO 3  on Al 2 O 3 . The process is particularly suitable for separating isobutene from butene-1 and/or butene-2 (diisobutene being separated as such from other oligomers), and the separation of isobutene from propylene is also exemplified. After the above process the remaining olefins may be dimerized, or (preferably after removal of any ethylene and propylene) disproportionated, in either case to obtain a C 6-8  olefine feedstock for the oxo process.

Abstract: 1,129,542. Automatic focusing; fibre optics. GENERAL AMERICAN TRANSPORTATION CORP. Dec.20, 1965 [March 1, 1965], No. 53963/65. Headings G2A, G2J and G3R. [Also in Division H4] In a method and apparatus for automatically focusing on an object within a field of view, first and second mechanisms scan an image, spaced a predetermined distance in front of and behind respectively the focal plane of the optical imaging system, of a small portion of the field of view which includes the area of contrast of the light intensity of the object, corresponding first and second electric signals are generated, related to the intensity of light received by the respective scanning mechanisms, and the inequality of amplitudes thereof operate a motor to adjust the imaging system to focus the object on to the focal plane. The embodiment is a twin-lens reflex camera (Fig. 1) the main (12) and viewing (13) lens being arranged to be moved relative to the photographic film (18) so as to focus the object thereon; part of the light through the main lens system is diverted by parallel inclined mirrors (31, 21) to an optical fibre bundle 51 Fig. 3 having its inlet behind focal plane 20 and to a second optical fibre bundle 61 having its inlet in front of that plane, the magnitude of the separations of the inlets of the bundles from the plane 20 being equal. Member 47 is rotated by an electric motor 55 thereby causing scanning by the inlets of the bundles over parallel circular paths of the same radius. A photo-electric detector 70 receives light from the exits 53, 63 of the bundles. A stationary semi-circular mask 80 with a horizontal upper edge 81 is added. The electric circuit (Fig. 4) includes a transistor amplifier (110) connected to the output of the photo-detector (70), the amplifier output being fed via a fixed contact (136) to a switch(131) having semi-circular plates driven by gearing from the aforementioned motor. The signals arising from the two bundles 51, 61 are thereby separately rectified (140, 150), the rectifier outputs being transistoramplified (160, 170). A polarized differential relay (180) operates on the difference of the rectifier outputs and controls the direction of rotation of an electric motor (91) which is mechanically coupled to the mountings of the lenses which are thereby moved until equal light intensities are scanned at the planes 54, 64, Fig.3.

Filed: 1971-11-30
Abstract: 1375419 Spray carburetters H MORGENROTH 30 Nov 1971 55635/71 Heading F1B A carburetter comprises a fuel-air mixture outlet 6, Fig. 1 discharging into a fuel mixing region 7 which has upstream thereof a throttle valve 8, a contoured metering rod 1 extending into a fuel metering orifice 2 fed by a fuel level holding device, the rod and valve being coupled so that the rod is displaced axially when the valve is rotated. The coupling means comprises a lever 10 with three linkage points, the third linkage point 15 being adjustable so that changing its position also changes the axial position of the metering rod and the flow area of the metering orifice. The linkage point between the lever (10), Fig. 3 (not shown) and spring plate (19) is offset so that the resulting couple tends to tilt the rod 1 towards the orifice wall. Fuel from duct 25 passes through an emulsion chamber 3 to orifice 6. The rod section 34 reduces the flow area of orifice 6 at idle and low engine load. In modifications the air bleed 4 spans into a small auxiliary Venturi (4a), Fig. 5 (not shown) and the orifices are spaced farther apart to co-operate with a rod having a cylindrical section (52) Fig. 4 (not shown) which maintains a constant flow area at the emulsion orifice 6 in the idle range. The straight taper on the rod may be replaced by a profiled taper to achieve a desired fuel/air ratio at each throttle position. The carburetter is arranged to maintain the correct fuel/air ratio at full throttle low speed conditions by use of a variable spring-bias load on diaphragm 22A. At full throttle the second spring 31 is inactive and only a constant bias spring 30 keeps the inlet valve 26 open until a fuel column (representing fuel pressure 'c') overcomes the spring 30 and pushes down the diaphragm to close the valve. In the part-load position of Fig. 1 an extension 32 of rod 1 activates spring 31 to cancel part of the  pressure of spring 30 to lower the fuel level (pressure 'b'). In a modification the spring 31 is replaced by a spring (41), Fig. 6 (not shown) attached to the side of the chamber.

Abstract: 1280194 Cryogenic recovery of ammonia and hydrogen MESSER GRIESHEIM GmbH 18 Nov 1969 [19 Nov 1968] 56382/69 Heading B1L [Also in Division F4] In the cryogenic recovery of ammonia gas and hydrogen enriched gas from a pressurised stream of gas emerging from a catalytic ammonia synthesis reaction the refrigeration required is obtained from internal heat exchanges. The feed gas, which also contains nitrogen, argon and methane, is passed through line 10 to be cooled in heat exchanger 11, and thence via manifold 13 and valves 14, 15 to heat exchangers 16, 17 for further cooling to condense the ammonia which is separated and recovered through valve 20. The remaining cold gas passes via pipes 21, 22 to an expander 23. The then partially expanded gas passes through the heat exchanger 16, to provide part of the refrigeration required in the process, and then via pipe 25 to one of the adsorbent beds 27A, 27B to remove any residual ammonia. The emergent gas is further cooled in heat exchanger 30 to condense most of the methane and argon which is collected in separator 32. The condensate is then depressurised in line 33 and the resultant vapour passed through heat exchangers 30, 11 to transfer its refrigeration to the counterflowing gases. The thus warmed gas is then either discharged via line 43 or used in part to strip the adsorbent beds 27A, 27B, being heated in exchanger 36 on the way, or recovered for use as a fuel gas. The gas remaining in separator 32 passes to heat exchanger 46 to condense remaining argon and nitrogen. The condensates are then depressurised in line 49 and passed as a vapour through heat exchangers 46, 30, 11 to utilise its refrigeration. The hydrogen enriched gas in separator 48 passes via line 51 to expander 52 and then through heat exchangers 30, 11 to utilise its refrigeration and is collected via line 54. In a modification, Fig. 2 (not shown) line 49 connects with line 33 so that the nitrogen, argon and methane fractions are taken off together, and the hydrogen, rich gas is recycled through heat exchanger 46 after expansion and before passing through heat exchanger 30.

Abstract: 1409924 Stabilizing polymers STAMICARBON BV 7 Dec 1972 [10 Dec 1971] 56631/72 Heading C3P A process for stabilizing particulate polymers comprises mixing the particulate polymer with one or more fusible stabilizers while the particulate polymer is at a temperature above the melting point of the stabilizer(s) and below the temperature at which the polymer normally agglomerates or sinters. The polymer may be a polymer or copolymer of an alkene, vinyl chloride, vinylidene chloride, styrene, α-methyl styrene, methyl methacrylate, methyl acrylate, acrylonitrile or methacrylonitrile; or a polyamide, polyester, polycarbonate or polyoxymethylene; and may be in the form of powder, fibres or granules. Other conventional additives may be incorporated with the stabilizer or during mixing, and catalyst residues in the polymer may be simultaneously deactivated by treatment with a gaseous alcohol or water vapour. Mixing is preferably effected without shearing, e.g. in fluidized beds or mixing drums. Many suitable stabilizers are listed and examples describe the stabilizing of polyethylene powder with n-octadecyl 2-(4-hydroxy-3,5-di-t-butylphenyl) propionate and dilauryl thiodipropionate.

Abstract: 1458206 Controlling foam plastics extrusion ALUMINIUM CO OF AMERICA 10 Dec 1973 [18 Dec 1972] 57168/73 Heading B5A [Also in Division C3] A foamed polymer of predetermined density is made by extruding a molten expandable polymer composition, e.g. containing a heat decomposable blowing agent, into air at atmospheric pressure where the polymer foams and then into a liquid quenching bath to stop foaming and to set the polymer and wiping or pressing against the quenched polymer in the bath and regulating the residence time of the composition in the air as a directly proportional function of the amount of bubbling appearing from the composition during the wiping or pressing to control the density of the foamed product. In the example a vinyl chloride homo- or co-polymer with vinyl acetate together with dioctyl phthalate, calcium carbonate or clay titanium dioxide, a calcium zinc stabilizer and azoclicarbonamide or an N- nitroso compound is extruded as a melt from extruder 1 (see Fig. 1) via strainer plate 2, die adapter 4 and die 6 into the atmosphere where the extrudate 11 foams while it is being passed over a roller mechanism 7 which can be adjusted in the direction of arrows A. The foam then passes into a water bath 13, which stops the foaming and sets the polymer, and is then wiped against a bar 20 causing release of gas 21 which can be collected in hood 22 and pass into flowmeter 23, the flow rate being transduced to an electric signal in transducer 24 whose output signal is compared in comparator 25 and deviations from the preset signal used to move roller mechanism 7 by means of a motor 26. The wiped foamed polymer can be passed over reversing rollers 8, to increase the path length in the bath, before leaving the bath to an air/wipe bar 9 and then being wound up on winder 19. The foamed polymer may be polyvinyl chloride having open-cells and of density 0À67-0À72 g./c.c. and may be used as a liner for a container closure.

Abstract: 1293573 Digital data storage systems; selective signalling PLESSEY CO Ltd 27 Nov 1970 [28 Nov 1969] 58406/69 Headings G4C and G4H A data storage system comprises a main store containing items of data at locations which are accessed by an arrangement including a keyboard and a microfilm display unit. Operation of the keyboard causes a corresponding frame of the film to be displayed. The data on the frame consists of a list of words (e.g. names of customers), each word, or name, corresponding to an item of data in the main store. The words appear aligned with push-buttons, and by operating that button which is adjacent a chosen name a signal is passed to a central processor which, in response to this signal and to a signal indicating the sequential position of the selected frame, accesses the corresponding item in the main store. In the embodiment described the names on any one frame have the same initial letter and are in alphabetic order with respect to their second letter, the list of names being continued on the next frame if necessary. By operating keys on the keyboard corresponding to the first and second letters of a required name a circuit, Fig. 6 (not shown), causes the microfilm to be scanned until the frame carrying the name is presented on the display. Each frame carries a binary code in photo-electrically or magnetically readable form, the code indicating a letter which is either the initial letter of the names on the frame or is the second letter of the first name on the frame. The code also indicates whether it represents an initial letter or a second letter. The group of frames carrying customer names having the same initial letter may be followed by a group of frames carrying names of suppliers, followed by a group carrying names of products, the customer, supplier, and product names all having the same initial letter. To prevent the wrong frame being located in such a case, the operator can indicate whether the required name is that of a customer, supplier, or product, the circuitry causing the relevant frame to be displayed. When the frame has been located circuitry (not described) passes to the processor a signal indicative of the ordinal number of the frame, and this signal, with that from the operated button adjacent the required name on the display, causes the processor to access the required data in the main store. The microfilm is prepared from the data in the main store, circuitry (Fig. 7, not shown) sensing the initial and second letters of names in the store and causing the appropriate code to be recorded on each frame.
