Title: Improvements in and relating to means for determining angular acceleration
IPC: G01P15/03
Filed: 1934-02-08
Abstract: 433,306. Fluid - pressure brakes. SMITH, D. M., 37, Church Street, Stretford, Manchester, and ASSOCIATED ELECTRICAL INDUSTRIES, Ltd., Crown House, Aldwych, London. Feb. 8, 1934, No. 4247. [Class 103 (i)] [See also Groups XIX and XXVI] A device for indicating and controlling the angular acceleration of a rotating body comprises a helically coiled tube 1 rotated about its axis x-x at a speed corresponding to that of the rotating body and having its ends 2, 3 arranged along the axis so that the inertia of a body of liquid contained in the tube causes the axial displacement of the liquid when acceleration or deceleration takes place. The coil may vary in radius and may be limited in length to form only part of a single complete coil. The liquid may act upon pressure-sensitive devices embodying either a bellows moving a toothed sector, or a coiled tube tending to straighten out under increase of pressure. By placing one end of the tube at a greater radius from the axis of rotation than the other end, a device sensitive to both speed and acceleration is obtained. The displacement of the liquid may be used to control the acceleration of a body, for example, in the brake governor gear described in Specification 392,252, wherein the inertia governor may be replaced by the coiled tube device.

Title: Gearboxes
IPC: G05G5/02
Filed: 1973-01-27
Abstract: 1410892 Change-speed control BRITISH LEYLAND UK Ltd 28 Jan 1974 [27 Jan 1973] 4267/73 Heading F2D A gear lever striker arm, connected to a selector shaft by a yoke (not shown), has an end 22 movable in three planes corresponding to 1st and 2nd, 3rd and 4th, and 5th and reverse ratios, and is prevented from being moved directly from the 1-2 plane to select 5th ratio by a stop 13 turned up from a plate 12 welded to a plate 11 which is slidable between guides 15. The striker end 22 operates in an aperture in the plate 11 which aperture is formed with a narrow portion 23 so that whenever the gear lever is returned to neutral in the 1-2 plane the plate is returned to the position shown in which the stop 13 is positioned so that the gear lever cannot be moved to the 5-R plane to select 5th ratio. The lever may, however, be lifted to clear the stop 13 and a reverse stop 24 to select reverse. When the lever is operated in the 3-4 plane the end 22 coacts with an enlarged part of the opening in the plate 11 providing lost motion so that when the lever is returned to neutral from 3rd or 4th ratio the plates 11, 12, and consequently the stop 13, remain displaced from the position in which movement into the 5-R plane is prevented. Cam surfaces 25 cause the plates 11, 12 to be centalized on movement of the striker end 22 into the 1-2 plane. In a modification, a pivoted, slotted plate takes the place of the assembly 11, 12, 13.

Filed: 1925-02-16
Abstract: 229,352. Two-Tone Corporation, (Assignees of Mijer, P.). Feb. 14, 1924, [Convention date]. Stencils and stencilling.-Designs are produced on textiles and the like by applying colour through a stencil prepared by securing shrinkable fabric to a frame, subjecting the fabric or a portion thereof to treatment to shrink it, and blocking out the design by means of an impermeable, material. The colour preferably consists of a mixture of gum tragacanth and dyeing materials, and the impermeable material of beeswax or " slow size," the latter consisting of boiled linseed oil with sufficient driers to complete the drying action in forty-eight hours. Complementary stencils may be applied in succession to produce a composite design. A piece of bolting cloth 1 is attached, as by sewing, to a border 2 of shrinkable material such as muslin, the border is tacked on to a frame 4 and is moistened to shrink it, and white lead paint is applied to the margin 5 to bind the muslin in position. The frame is now immersed in water and dried to shrink the cloth 1 and so cause it to be tightly held in the frame 4. The design being blocked out, colour is forced through by means of a spatula, the fabric being supported on a table covered with layers of felt, oilcloth, and muslin.

Patent GB-848190-A (GB)
Title: Process for separating hydrocarbons
IPC: B01D53/12
Filed: 1959-02-09
Abstract: Normal hydrocarbons are separated from mixtures with non-normal organic compounds by passing in the vapour phase over a 5   molecular sieve and eluting the adsorbed normal hydrocarbons with a vapour stream comprising one or more normal hydrocarbons the highest boiling of which contains in the molecule a number of carbon atoms at most equal to and differing by no more than two from the number of carbon atoms per molecule of the lowest boiling hydrocarbon to be separated from the feed.  Where the eluent is of the same degree of saturation as the adsorbed hydrocarbon it may contain one or two carbon atoms less, where the eluent is less saturated the number of carbon atoms is two less and where the eluent is more saturated the number of carbon atoms is the same or one less.  Normal hydrocarbons may be separated from branched aliphatics, naphthenes, aromatics, heterocyclics, secondary straight chain alcohols, mercaptans, nitriles and halides, branched chain ethers, thioethers and secondary amines.  In one embodiment a C5-C10 fraction is passed through a molecular sieve until C8 normal hydrocarbons appear in the effluent thereby obtaining a mixture containing C5-C7 normal hydrocarbons but none higher.  The adsorbed hydrocarbons may then be recovered using as eluent a normal heptane or hexene. Adsorption and desorption may be at subatmospheric pressure to 1,000 p.s.i.g., 25 DEG -360 DEG  C. and 0,-40 vols./vol./hr., desorption temperature preferably being within 50 DEG  C. of that for adsorption.  An inert gas may be mixed with the feed and/or eluent, e.g. helium, nitrogen, hydrogen, methane or carbon dioxide, and the sieve may be purged after adsorption and/or desorption.

IPC: G07F17/24
Filed: 1959-02-09
Abstract: 845,347. Parking meters. BLOCTUBE CONTROLS Ltd. April 30, 1959 [Feb. 9, 1959], No. 4523/59. Class 27 In a modification of the parking meter of Specification 775,509, in which a coin gate carrier 3 must return fully to rest position after insertion of a coin so that a lever 11 is moved to a position freeing a governor wheel, the full return of the carrier is prevented if a coin is inserted of a size other than that of the coin or coins that the mechanism is designed to take. If a sixpence or a shilling is inserted to raise the coin gate carrier 3 for connection of a pawl 8 with a drive link 7 loaded by a spring 10, a pin 31 on the carrier rides up the face of a cam unit 20 rockably mounted at 21 and pressed against a stop 29 by a spring 28. A sixpence moves the pin up to rest momentarily on the inturned edge 32 of an inner spring element 26 and, when the sixpence has passed the gate 2, the carrier returns and the pin moves back along the same path over the face of an outer spring element 24. A shilling moves the pin up to the outermost edge of a lug 33 above a V-notch 27 and, on return of the carrier, jumps across the V-notch to return along the outer spring element 24. If, however, a coin of intermediate size is inserted, the pin 31 moves into the V-notch and the spring 28 rocks the cam unit so that the pin bears on the apex of the notch. As the carrier returns, the pin rides inside the inner spring element 26 until it meets a lug 32. The carrier is thus prevented from returning fully and a lug 40 on a trigger member 12 cannot move into a recess 44 in the coin gate carrier 3 and engage a lug 43 on a trigger lever 41 so as to move the lever 11 to release the governor wheel. On subsequent insertion of a coin, the incorrect coin will be discharged into a collecting box and the pin 31 will ride up between the elements 24, 26, the element 24 flexing to allow the pin to pass out into its normal path.

Title: An improved device for the periodic opening or closing of electric circuits
IPC: H04M19/02
Filed: 1936-02-18
Abstract: 462,773. Electromagnetic interrupters. SIEMENS BROS. & CO., Ltd., and HUMPHRIES, H. E. Feb. 18, 1936, No. 4881. [Class 38 (v)] [Also in Group XXXIX] To effect the periodic opening and closing of an electric circuit or circuits such as the impulsing circuits in automatic telephone systems, a self-restoring electromagnetic relay is employed which has an operating winding connected in series with a control contact across a source of supply and a retarding winding connected in series with a capacity across the operating winding, the control contact being opened as the relay operates and closed as a consequence of the release of the relay. As shown in the Figure, the self-restoring relay Y is provided with two windings (I) and (II), the latter being in series with a capacity comprising condensers CA and CB and a resistance R. When switched into circuit by an external switch x current flows over the make-before-break contact y to the two winding circuits, the charging current through the winding (II) causing this winding to oppose the operation of the winding (I) and delay the effective operation of this winding. On operation of the contacts the winding circuits are broken and a circuit to a controlled line PW completed. In the restoring movement, the condensers discharge through the two windings in series in such directions that the two windings assist each other in maintaining the flux already existent and thus retard the restoring movement. The retardation effect may be increased by connecting additional condensers between linked points TA, TB or may be varied by variation of the value of the resistance R.
