Title: Counter
IPC: G06M1/36
Filed: 1963-09-30
Abstract: 1,055,148. Counter. ADDRESSOGRAPHMULTIGRAPH CORPORATION. Sept. 30, 1963 [Feb. 20. 1963], No. 38482/63. Heading G4D. A counter, e.g. for use with an automatic printing or duplicating operation, comprises a rotor 47, reversible drive means whereby the rotor may be driven either in a counting direction or in a setting direction, and digit preselector means comprising a plurality of stops 105 (Figs. 1, 2, 3 and 6, not shown) each stop being movable from a retracted position into an extended position (Fig. 6, not shown) within the range of abutment means 51 mounted on the rotor. As illustrated in Figs. 1 and 2 (not shown) a reversible motor 79 drives gear 77 meshing with gears 27 which through friction clutches 29 drive shafts 21 for each digit counter. To start the motor 79, switch 169 (Fig. 9, not shown) is operated which allows the motor to rotate in the direction of arrow C and places the counter in condition for operation. Whenever the controlled apparatus 177 performs the operation to be counted the switch 173 is closed and opened which sends a pulse via conductors 170, 179 through solenoid 73 of the units assembly thereby permitting one tooth of rotor 47 to escape in the counting direction. Transfer operation.-At one portion of the units shaft 21, a units pin 91 (Figs. 2 and 8, not shown) coacts with switch 81 to close same and there is an overlap in which switches 81 and 173 are closed during which a pulse via conductors 181, 187 and lens solenoid 73 allows tens rotor 47 to escape one tooth. Control (Fig. 9, not shown).-When the tens shaft reaches its " 0 " or control position, the tens pin 91 will also close tens switch 93 (Fig. 8, not shown) and hold it closed. The units counter will continue to decrease until it reaches " 0 " or oontrol position, whereupon units switch 93 is closed by units pin 91. With both switches 93 closed, a control circuit is completed which energizes solenoid 191 to trip the controlled apparatus 177. Setting (Figs. 1 to 6, not shown).-If a number, e.g. 12 is to be set in the counter, button 1 of the tens counter and 2 of the units counter are depressed and held in the depressed state by latch 111. The ends 106 of the buttons are then within the range of abutment 51 such that when manual set button 159 (Fig. 9, not shown) is depressed, the motor 79 and thus rotors 47 rotate in the direction of arrow S. The rotors will be stopped when abutments 51 engage ends 106 and thereafter the drive slips at clutches 29. When button 159 is released the motor will reverse to the count direction C. The ends 106 do not interfere when the rotors are operating in the count direction since abutments 51 idle past them. The push-buttons may be set by solenoids receiving their signals from any convenient source.

An apparatus for flushing out and lubricating the bearings of a spinning and twining spindle comprises a lubricating head 4; a tube 19, carried by the head 4 and reciprocably displaceable therein between an operative position, when the tube 19 is fitted on a foot bearing 23 and an inoperative position, when the tube 19 is removed from the foot bearing 23; a fresh-oil inlet 30 and a used-oil outlet in the lubricating head 4, controlled by the tube 19; and a used oil-storage compartment 12 which empties when the tube 19 reaches its non-operative position. In an embodiment, a mobile oil tank 3, having fresh- and used-oil containers 1, 2, supplies fresh oil through pipe 5 which is connected to the inlet 30 in the head 4 and receives used oil through a pipe 6 which is connected to the outlet in the head. The fresh-oil container 1 is charged, through a safety valve 7, with compressed air and the used-oil container 2 has air-vents 8 therein. The head 4 has a hollow grip 11 screwed on to a distributer 10 and a space 12 in the grip 11 is limited in the downward direction by a tubular member 14 which is housed in a bore 13 of the distributer 10. The member 14 has two horizontal bores 15, 16, and vertical grooves 17, 18, connected therewith, which connect the space 12 with the interior of the tube 19 and connect the bore 20 of the member 14 with the bore 13. The member 14 receives the upper closed end of the tube 19 and is pierced so that the bore 20 communicates with the space 12. The tube 19 has a horizontal bore 22 at its upper end; is open at its lower end; is limited in movement by a ring 24, which is engageable with the lower limit of the bore 13 and with the member 14; and has a number of internal grooves 25 therein which allow passage of the lubricant when the pipe is in the operating position, Fig. 1 (not shown). Packings 26, 27 surround the pipe 19 and are held by bushings 28, 29 and, in the operative position, the packing 27 is bridged by the grooves 25 and lubricant flows to a bearing 35 and into a sleeve 36 from where it passes to the foot bearing 23, having a groove 37 therein. The lubricant is then forced through a sump 39 and through a bore 38 in the foot bearing 23, then surges upward through the tube 19 and passes, through the bores 22, 16 and the groove 18, into the space 12 until the air therein is compressed sufficiently to stop the flow of oil. On removing the head 4 from the spinning and twining spindle, the pipe 19 is returned by the spring 21 and the used lubricant flows from the space 12 and passes through the bore 15 and the groove 17 to the outlet which leads to the used-oil container 2, via the pipe 6.

Abstract: 1,008,728. Magnetic erasing heads. TELEFUNKEN PATENTVERWALTUNGS G.m.b.H. Oct. 17, 1962 [Oct. 17, 1961], No. 39231/62. Heading G5R. A two-track erase head has two two-gap sytems 1, 2, Fig. 1, separated by a Z-form screen 10, the head geometry being such that the gaps 3, 6 extend to the centre-line of the tape, while the gaps 4, 5 extend sufficiently to erase standard half-tracks 1a, 2a. Where a tape has previously been used for full-width recording, the arrangement ensures that there is no central unerased band to cause interference on a misaligned stereo playback head. The wider gaps 3, 6 are also longer in the direction of the tracks than are the gaps 4, 5, it being found, in practice, that the order of meeting the gaps having neligible effect on the erasing efficiency. The members 9, Fig. 2, are preferably relieved at 12 to accommodate the windings 11 while permitting the compact assembly of Fig. 1.
Patent GB-395124-A (GB)
Abstract: 395,124. Colour photography. I. G. FAR,BENINDUSTRIE AKT.-GES., Frankfort-on-Main, Germany. April 28, 1932, No. 12264. Convention date, May 2, 1931. Drawings to Specification. [Class 98 (ii).] Three-colour photographic or kinematographic negatives are produced on a pack comprising a lenticular film superimposed on a smooth film, the lenticular film being nearer the objective, with which a two-colour selecting filter of the kind usual in lenticular-screen colour photography is associated. The films are so sensitized and the filter colours are so chosen, that two component colour-record images are produced on the lenticular film, and the third component on the smooth film, the latter being either in continuous tone or in broken tone. Positives are printed from the negatives by any known process, such as that described in Specification 353,121, and may be projected additively. In one example, a green-sensitive lentioular film is superimposed on a red-sensitive smooth film with a red or yellow filter separating the two films, and the pack is exposed in a camera in which a colour filter having blue and yellow areas is associated with the objective, so that blue and yellow records are produced on the lenticular film, and a broken-tone red record is produced on the smooth film under the blue record on the lenticular film. In a modification, the blue area of the filter is replaced by purple, and although the films record the same colours as before, the red record is continuous in tone, being produced under both the blue and the yellow lenticular records. Specification 10611/09, [Class 98 (ii), Photographic processes &c.], also is referred to. The Specification as open to inspection under Sect. 91 states that the three records may be printed on a single lenticular film. This subject-matter does not appear in the Specification as accepted.

Abstract: 847,690. Making gratings; casting composite articles. VEREINIGTE LEICHTMETALLWERKE G.m.b.H. Dec. 19, 1957 [Dec. 20, 1956; July 5, 1957; Oct. 1, 1957], No. 39538/57. Classes 83 (1) and 83 (2). A metal article having an open-work honeycomb structure is made by continuously casting ingots with a number of heat-resistant non- metallic inserts in strip, band, or plate-form, which remain mechanically-separable from the ingot-metal and capable of disintegration under pressure so as to form in the ingot at least three equidistant parallel, staggered rows of separating zones 95, subjecting the casting to a non-cutting shaping operation such as rolling or extrusion, and mechanically separating the casting along said zones by pulling opposite sides of the casting so as to form the open-work structure. The separating elements may be of mineralwools such as slag and glass-wool, asbestos, glass &c. fibres or graphite, and networks of such materials may be used to produce a network of separating-zones. The inserts may be coated with a heat-resistant coating such as silicone, dry graphite powder, or a slurry of graphite in water. The casting may be carried out in a vacuum, or inert atmosphere, or under an inert liquid or salt melt. Reference has been directed by the Comptroller to Specifications 784,484 and 799,700.

IPC: D06M13/364
Filed: 1966-04-15
Abstract: 1,177,503. Shrinkproofing wool. I.W.S. NOMINEE CO. Ltd. 4 April, 1967 [15 April, 1966; 6 Sept., 1966], Nos. 16742/66 and 39835/66. Heading DIP. Wool fibres are rendered resistant to shrinking by a continuous process in which they are impregnated with an aqueous solution containing at least 1% by weight of an alkali metal chlorocyanurate, e.g. the sodium and potassium salts of dichloroisocyanuric acid, and having a pH of 5-7, continuously transferred to a residence zone where they are kept for a period of at least half a minute and then treated with a dechlorinating agent, e.g. an aqueous solution of an alkali metal sulphite or bisulphite or a mixture thereof or of hydrogen peroxide. The fibres are preferably exposed to the atmosphere during their time in the residence zone either by passing them over or through a succession of guides disposed in air between the impregnation zone and the dechlorinating zone or by allowing the fibres to collect on a suitable support or empty container between these two zones. The pH of the solution of the chlorocyanurate which may contain a wetting agent may be adjusted by the addition of formic, acetic or lactic acid and the fibres may be immersed in this solution for up to 10 seconds, the solution being maintained at 15‹- 35‹C. The proportion of solution remaining on the fibres when they leave the impregnation zone may be 25-200% by weight. Raw wool, combed or carded skeins, yarns, woven fabrics, knitted goods and articles made therefrom, e.g. blankets, may be treated, the wool fibres optionally being in admixture with other fibres, the proportion of wool in these mixtures being at least 30% by weight.

Title: Data transfer apparatus
IPC: G11C19/08
Filed: 1962-10-23
Abstract: 997,492. Circuits employing thin magnetic films. INTERNATIONAL BUSINESS MACHINES CORPORATION. Oct. 23, 1962 No. 40007/62. Heading H3B. Two thin magnetic films 1 and 2, Figs. 1 and 2, coupled together by a stripline 3 have the coupling between the film 1 and film 2 higher than the coupling between film 2 and film 1. The directional dependence of the coupling is shown to be due to the rectangular shape and different orientations of the films 1 and 2 and to their different permeabilities. The distance between the two conductors of the stripline 3 is made proportional to the width of the stripline 3 in order to keep the characteristic impedance of the stripline independent of position. In the shift register shown in Fig. 6 the controlling element is formed by two thin films 14 and 15 whereas the element controlled by these films is formed by thin films 16, 17 connected in parallel with respect to stripline 10. For the purpose of transferring information to the next stage these films 16 and 17 are connected in series with respect to stripline 10<SP>1</SP>. In the shift register of Fig. 14 the rectangular thin films 51-55 are arranged with their easy axis of magnetization at a small angle e to the axis of a stripline 45 carrying a rectangular pulse current i. Stripline 60 carries a constant bias current i 2  so that the effect of currents i 1  and i 2  together is to produce magnetic fields alternately tending to switch the A elements 51, 53, 55 and the B elements 52 and 54 from the easy direction to a hard direction. As an A element is switching to the hard direction the B elements are returning to the easy direction so that the pulses induced in the striplines 61-65 and having a polarity indicative of the data stored in the A elements influence the choice of the easy direction by the B elements. Because of the directional dependence of the couplings the B elements always respond to the information stored in the A element to their left. During the next half cycle information is transferred from the B elements to the A elements to their right. The shift register may be formed by producing a thin copper layer 50 on a glass substrate the other components being mounted thereon with silicon oxide insulating layers between. The copper layer 50 may form the return conductor for the strip lines.

Abstract: 403,593. Time switches. SPILLANE, M., 3, Southern Road, Cork, Irish Free State. July 29, 1933, No. 21348. [Class 38 (v).] The hour hand 6 of a clock makes contact with telescopic arcuate contact segments 3, 4 to complete a circuit for a given period from terminal 2 through the clock mechanism, hand 6, segments 3, 4 and terminal 19. The period is adjusted by means of clamping screws 13, 14 slidable in slots 11, 12 in the clock face, the segments 3, 4 being insulated from the clock. In order to ensure that the circuit is only completed once in twenty-four hours, the contact 4 is separated from terminal strip 19 and the gap is bridged by contacts on one arm of a rotatable insulating cross head 5. As the hand 6 leaves the segment 4 it turns the crosshead through a right angle to break the circuit at 4, 19 so that when the hand again contacts with segment 3 circuit is not made. Circuit is prepared at 4, 19 when the hand leaves segment 4 again and the circuit is made again after twenty-four hours. Specification 390,630 is referred to.
