Title: Method of and apparatus for winding into a cross-wound cone yarn fed at constant speed from a work station
IPC: B65H59/38
Filed: 1975-11-01
Abstract: 1516370 Winding yarn CENTRALNY OSRODEK BADAWCZO - ROZWOJOWY MASZYN WLOKIENNICZYCH "CENTMATEX" 1 Nov 1975 45595/75 Headings DID and D1T To wind a cross-wound cone, yarn is fed at constant speed from a work station, the cone is rotated by a friction drive element, the running yarn is continuously and temporarily stored in a receptacle, the amount of yarn filling the receptacle is measured, and the speed of winding is controlled in accordance with deviations from the filling of the receptacle. Yarn is fed from spinning chamber 2, Fig. 1, through delivery rollers 1 into evacuated chamber 4 where the yarn is laid into adjoining loops, Fig. 2, between openings 7. The yarn then passes through yarn brake 11 and cleaner 12 and is traversed by guide 13 onto conical package 15 rotated by point contact with one of a succession of conical sections of common shaft 14, Fig. 3. Package 15 is mounted on spindle 17 carried by arm 19 pivotable upwards on shaft 20. Spindle 17 is carried on arm 19 by slider 18 reciprocable by pneumatic ram b. A change in the amount of yarn stored in chamber 4 is sensed by pressure sensor 8, or by two capacitor plates (Figs. 4 and 5, not shown), or by a light source and photo-element (Figs. 6 and 7) not shown, which control the air supply to pneumatic ram b to thereby move the contact point of the package with a conical section of shaft 14 to speed up or slow the package. Alternatively, Fig. 3, when the amount of yarn in chamber 4 increases, pneumatic pulses are not delivered to chamber 24 from b, and pressure in ram chamber 28 pivots lever 38 about pivot 36 to remove brake 40 from spindle 17. Lever 38 then contacts belt 42 and lever 37 is pivoted downwards so that the package is rotated. If the amount of yarn decreases, pressure pulses sent periodically to chamber 24 pivots lever 38, applies brake 40 and pivots lever 37 upwards so that the package is not rotated.

Title: Providing a measure of cross-sectional area of an object
IPC: G01B7/12
Filed: 1971-09-30
Abstract: 1351964 Measuring dimensions electrically STIFTELSEN INSTITUTET FOR MIKROVAGSTEKNIK VID TEKNISKA HOGSKOLAN I STOCKHOLM 30 Sept 1971 [30 Sept 1970] 45673/71 Heading G1N The cross-sectional area of a wire, girder, tube &c is determined by inserting it in a micro-wave cavity resonant at two distinct frequencies and detecting the resultant shift in the two resonant frequencies. The cavity may be in the form of a right circular metallic walled cylinder provided with holes at each end for the passage of a wire and dimensioned to be resonant at a first frequency for TM110 oscillations and a second frequency for TE111 oscillations. Increases of the cross-sectional area cause the first frequency to increase and the second frequency to decrease when the cavity is swept by a variable frequency oscillator. The cavity output voltage is detected and processed to give the difference in the two frequencies as a measure of the area. The thickness of a dielectric layer on a metal wire is determined by pressing the uncoated wire through a first micro-wave cavity and then after coating through a second micro-wave cavity, the difference between the two measurements giving the thickness of the layer.

An oil-bearing formation penetrated by a well is consolidated by injecting from the well at a temperature of 93 - 260C a mixture of steam, condensed steam, and air for a period adequate to convert oil in the formation to coke bonding the particles of the formation into a strong permeable mass. The mixture is injected for at least 8 hours, and the initial temperature of injection may be less than 93 C. The injection of the mixture may be followed by an injection of steam to make the well produce. Where the formation contains no oil fraction suitable for coking, a heavy, readily cokable, oil is injected into the formation prior to the injection of the mixture.

Title: Method of making precision-shaped internal surfaces on glass vessels
IPC: C03B5/167
Filed: 1965-10-28
Abstract: A method of making a precision shaped internal surface on a glass vessel comprises inserting a pre-shaped mandrel having a gold-rich surface composed of a gold-platinum alloy into a glass vessel, heating the glass vessel to at least a soft condition and shaping the internal surface thereof on the mandrel to the contour of the mandrel surface, permitting the glass vessel to cool and then removing the vessel from the mandrel.  The method is particularly applicable to the manufacture of rotameter tubes wherein a tube of borosilicate glass is fitted over the mandrel, heated to softening point and then vacuum collapsed on to the mandrel to become precision shaped, allowed to cool and then removed.  The mandrel comprises a stainless steel or molybdenum base having a tapered end portion which is first coated with fused aluminia or zirconia.  A thin sleeve of a platinum-rhodium alloy (90%-40% Rh) is then accurately machined on to the coated mandrel. Then a thin layer of platinum is electro-plated on to the mandrel followed by a thin layer of gold also by electro-plating.  The composite mandrel is then heat treated so that the platinum and gold interfuse to give a gold-rich surface.ALSO:A method of making a precision-shaped internal surface on a glass vessel comprises inserting a pre-shaped mandrel having a gold-rich surface composed of a gold-platinum alloy into a glass vessel, heating the glass vessel to at least a soft condition and shaping the internal surface thereof on the mandrel to the contour of the mandrel surface, permitting the glass vessel to cool and then removing the vessel from the mandrel.

Filed: 1965-10-29
Abstract: 1,110,923. Character recognition. INTERNATIONAL STANDARD ELECTRIC CORPORATION. 29 Oct., 1965 [5 Nov., 1964], No. 45868/65. Heading G4R. In automatic character recognition apparatus, photo-cells feed first bi-stables via AND gates controlled by second bi-stables controlled by the first bi-stables. Signals obtained from a vertical column of photo-cells (1) past which a character moves horizontally are passed via amplifiers and threshold devices (3) to respective AND gates (4), one per photo-cell, which sample selected ones during each column position, the samples from a given AND gate passing via a respective first bi-stable (5), and then a respective second bi-stabie (6) enabled by clock signals in alterna. tion with the AND gates, to a store. Each AND gate is controlled by one or more of the second bi-stables directly or via an OR gate, so that a 1 (black) signal arriving at a given AND gate will be passed (a) if the corresponding second bi-stable is currently storing 0 (Fig. 2, not shown); or (b) if it and the two adjacent second bi-stables are all storing 0 (Fig. 5, not shown); or (c) if any one of these three bistables is storing 0 (Fig. 4, not shown); or (d) if either no second bi-stable or the respective second bi-stable and that above it or the respective second bi-stable and that below it is/are storing 1. The above alternatives variously thin vertical lines to one column width, improve recognition of poorly printed rounded corners, and/or remove part of horizontal lines. Remaining parts of horizontal lines may, if desired, be eliminated in the following recognition circuitry on the grounds of depth, or by grouping the photo-cell outputs via resistors before feeding the AND gates so a given AND gate only receives a 1 signal if black is encountered in several adjacent horizontal rows.

Abstract: 1411827 Infra-red imagery ELTRO GmbH GES FUR STRAHLUNGSTECHNIK 3 Oct 1973 [13 Oct 1972] 46145/73 Heading H4F In an airborne infra-red scanner, improved signal to new ratio is achieved by scanning a line of detectors 4<I>-4<VI> over the terrain along a direction 3 transverse to the direction 2 of movement of the aircraft, and integrating the outputs of each detector resulting from the same element 8 of terrain. The output of each detector 4<I>-4<VI> is connected to corresponding contacts I-VI of VI synchronous rotary switches 7<I>-7<VI>, the rotating pick-off contacts of which are connected to storage capacitors 6<I>-6<VI>, and are progressively delayed by one contact from switch to switch. The changes on the capacitors are fed to respective contacts I-VI of a contra-rotating switch 7<VII> providing the output signal 9 from its pick off contact. Thus when a terrain image element 8<I> is on detector 4<I>, a corresponding charge is fed to capacitor 6' via contact I of switch 7<I>. Movement of the image element 8<I> from detector f detector is followed by the movement of the rotating contact of switch 7<I> from contact to contact and the accumulation of the VI signals due to element 8' on capacitor 6<I>. After the accumulation, the rotating contact of switch 7<VII> reaches contact I and the accumulated signal. Discharge contacts VII are provided.

Title: Coin-freed mechanism for use with petrol pumps
IPC: G07F13/02
Filed: 1963-11-23
Abstract: 1,058,778. Coin-freed petrol pumps. A. B. GREEN. Nov. 23, 1963, No. 46343/63. Addition to 940,203. Heading G4V. In a coin-freed petrol pump which dispenses one gallon at a time to avoid demands in excess of actual need, a coin mechanism has a manually driven gear train displaced by a given amount on the insertion of a coin which couples the manual drive with the gear train, a manually operated switch to operate the petrol pump motor being blocked until a maximum number of coins has allowed the gear train to be displaced to a switch operating position, and a stop being provided to prevent acceptance of coins beyond the maximum number. The gear train is coupled to the quantity mechanism of the pump to set the mechanism while coins are being accepted but the gear train is decoupled by disconnection of a clutch to allow the quantity mechanism to be reset while the pump motor switch is operated and petrol is being dispensed. A split coin drum, one half of which is fast with a finger wheel and the other half of which is fast with the gear train, is presented with coins delivered down a shoot so that when slots in each half of the drum are put into alignment a coin enters the drum and couples the two halves which are then rotatable by the finger wheel. Once the drum is turned away from its normal position a cam controlled plunger couples the two halves of the drum and the coin is discharged. At the end of one revolution the cam releases the plunger and the drum returns to its split condition. A ratchet ensures that the drum rotates in one direction only. The gear train rotates cams which, after the appropriate number of revolutions of the coin drum, displace a lever blocking the motion of a manual plunger which switches on the pump motor and engage a stop associated with the plunger so that the train cannot be advanced further until the plunger has been pressed home. If it is desired to discontinue use of the pump under control of the coin mechanism, a dog clutch may be disconnected to sever the driving connection between the quantity mechanism and the gear train. The gear train may also carry a cam to initiate the dispensing of change from coin storage tubes.

Abstract: 1,169,648. Coaling method and apparatus. GILLETTE CO. 13 Oct., 1967 [14 Oct., 1966], No. 46735/67. Headings B2K and B2L. The sharpened edge of a length of razor blade Strip is coated by forming the strip into a coil such that only the sharpened edge is exposed at the face of the coil, rotating the coil about its axis, and spraying coating material on the sharpened edge by moving the spray along a path parallel to said face. A holder 58, carrying a flat coil 128 of razor blade strip with its sharpened edge disposed outwardly in a vertical plane, is rigid with a horizontal shaft 290 journalled in a carrier 280 slidably mounted on horizontal bars 218, 220 for movement, imparted thereto by drive means 228, into and out of a spray booth 212. When carrier 280 is in operative position within the latter, a gear 292, rigid with shaft 290, meshes with a gear 300 rigid with a shaft 301 journalled in a structure 302 pivoted on a shaft 314, gear 3C0 being in constant mesh with a gear 312 rigid with shaft 314. A pulley 316 on the latter is driven by a belt 318 for rotating holder 58 when carrier 280 is in the operative position. Lugs 310 on structure 302 are biased against collars 286 on carrier 280 by a spring 306. A spray gun 132, directed downwardly by 5 degrees, is mounted on a bracket 266 rigid with a carrier 268 slidable on a vertical bar 270 and in screwthreaded engagement with a screwed-shaft 272, rotation of which serves to move gun 132 along a vertical path intersecting the axis of rotation of carrier 58. A supply tank (250) for spray material is moved synchronously with carrier 268. The speed of rotation of shafts 272 and 314 is varied by control means to maintain a substantially constant relationship between the angular velocity of the portion of the coil currently being coated and the effective transverse speed of the gun 132.

Abstract: 1,116,212. Determining vehicle wheel alignment electrically. SPERRY RAND Ltd. Feb.15, 1965 [Nov. 29, 1963], No.47210/63. Heading G1N. Apparatus for measuring the "toe-in" or "camber" of vehicle wheels during rotation, while mounted on a roller test stand, comprises a pivoted carriage carrying rollers 5, 6 (Fig. 2) which in use bear against a wheel near the ends of a horizontal or vertical diameter and an inductive pick-off which senses the angular position of the carriage with respect to a datum and produces a signal representative of the said "toe-in" or "camber". The carriage includes a beam 3 pivoted on a bearing 4 and a rotary inductive pick-off 8 on a bracket 7 carried by the bearing 4. The pick-off rotor carries an arm 9 which rides against a roller 10 fixed to the beam 3 and is urged against the roller 10 by a spring biased second roller 11. Movement of the beam 3 about the axis of bearing 4 thus causes angular rotary motion of the rotor. The bearing axis is vertically disposed when measuring "toe-in" and arrangements are described whereby it can be horizontally disposed when measuring camber. In Fig. 3 the pick-off 8 is energized from a transformer 25 and its output is fed via an autotransformer 26 to a demodulating circuit comprising transistors 28, 29, 30, 31; the filtered output of which is fed to a meter 35. (The filter C37, R36, R38 removes signal components, due to eccentricities of the wheel tyre, at the rotational frequency of the wheel, during the test). When measuring toe-in, the pick-off may be adjusted to give zero output when the axis of the rollers 5, 6 is parallel to the longitudinal axis of the vehicle. A centre tapped potentiometer 34 supplies a biasing component of A.C. to the demodulator circuit and is pre-set in accordance with the required "toe-in" angle, such that it will exactly neutralize the pick-off output and the meter will indicate zero when the wheel is adjusted to the required "toe-in" (or camber). One carriage may be provided for each front wheel and a similar circuit 40 is associated with the other carriage, the potentiometers being mechanically linked. Alternatively the biasing component from the potentiometer may be omitted and the meter arranged to read actual values of toe-in or the pick-off set to give zero output at the required toe-in, toe-out or camber.
