Title: Improvements in and relating to coin freed lock and like mechanism
IPC: G07F17/14
Filed: 1934-06-27
Abstract: 434,844. Coin - freed door lock. LEGGOTT, R. B., Silens Works, East Parade, Bradford, Yorkshire. June 27, 1934, No. 18926. [Class 27] Coin-slit closing-devices.-In a coin-freed lock of the kind such as is described in Specification 162,827, [Class 27], in order to prevent jamming by the insertion of a second coin while the first coin is in position to release the lock, a spring or gravity controlled piece A, Figs. 1 and 2, is pivoted to the tail piece 131 of the bolt B which carries a projection B<2> to receive the thrust of the coin when this is moved by a similar projection on a slide moved by the outside handle. Coin action, mechanical-connection; registering.-A coin in position between the projections engages the tail A<2> of the piece A and moves its top A<1> to close the coin-slit S. When the lock is provided with a counter C as shown, the projection B<2> is on a separate sliding piece T which acts against the tail B <1> of the bolt and allows the bolt to be moved by shutting the door without actuating the counter. In this case the coin-slit closing piece A is carried by the additional piece T. When the piece T is moved by the outside handle after insertion of a coin an incline T<2> thereon operates a lever C<1> of the counter C. Coin-discharging mechanism.-A Spring pawl or catch F engages indents or teeth T<3> on the piece T and retains this and the bolt in their actuated positions until the outside handle returns its actuating slide to normal position. A projection Fx on this slide trips the pawl F to allow the piece T and bolt to return to initial positions. A slight lost motion between the actuating slide and the piece T allows the coin to drop, a member fixed on the casing acting to force the coin downwards.

Title: Photographic transfer process
IPC: G03C8/40
Filed: 1973-04-19
Abstract: 1454271 Photographic transfer process KODAK Ltd 19 April 1974 [19 April 1973] 19026/73 Heading G2C A photo-sensitive heat-processable photographic material comprising a sensitive layer, the layer containing a binder and, as part of an image-forming system, a light-insensitive reducible metal salt of a straight-chain fatty acid having at least 10C is imagewise exposed, heated to develop a first image by reduction of the metal salt and to release fatty acid, and contacted with a receiving sheet whilst at a temperature above the melting point of the fatty acid so that fatty acid-containing material transfers from the developed areas to the receiving sheet to produce a transfer image. The imageforming system may comprise a compound which is decomposed to form a reducing agent on exposure to actinic radiation, or a reducing agent which is destroyed by actinic radiation, the sensitive layer being exposed to a negative of the desired image in the latter case. The material may contain an organic reducing agent, as part of the image-forming system, and a photo-sensitive compound, e.g. silver halide, capable, on exposure to actinic radiation of forming centres which catalyze the thermally induced oxidation/reduction reaction of a metal salt and reducing agent to form the first image. The layer may contain a binder which softens at the temperature at which the layer is held so that binder as well as fatty acid transfers to the receiving layer and a visible image is obtained (see Ex 1-3). The receiving sheet may have a hydrophilic surface and the fatty acid transferred to it may provide an oily ink-receptive lighographic printing image (see Example 4-7).

Title: Improvements in or relating to the coating of press-buttons and the like with colouring liquids
IPC: B05B13/02
Filed: 1938-06-27
Abstract: 502,850. Coating press-buttons &c. with liquids. MAGENER, W. June 27, 1938, No. 19037. Convention date, July 17, 1937. [Class 95] Press-buttons D, of magnetizable metal, spread upon a fixed iron plate 1 and held thereto by magnetism induced therein by an electric current, are coated, on their top surface, by spraying with a colouring liquid. This coating is dried, and, by means of a change-over switch, magnetism is now induced into the iron plate 2 which has been moved by a lever H through 180‹ to a position parallel with the plate 1. The press-buttons, now attracted to the plate 2, are carried therewith back through 180‹ and the uncoated surfaces thereof, now facing upwardly, are coated by spraying. The plate 2 is now de-magnetized and tilted, the buttons being collected in a storage container.
Patent GB-437638-A (GB)
Title: Improvements in matrix composing and line casting machines
IPC: B41B11/72
Filed: 1935-07-03
Abstract: 437,638. Type-bar-making machines. INTERTYPE, Ltd., 215, Farnham Road, Slough, Buckinghamshire. July 3, 1935, No. 19058. Convention date, Nov. 5, 1934. [Class 100 (iii)] In a matrix-composing and line-casting machine, the cast slug is ejected from the mould and stands upright upon one end on a shelf which is provided with side walls and from which it is pushed off by a sliding motion sideways, when it falls vertically into a shoot provided between the shelf and the galley. The galley 23 is mounted on a bracket 21 so as to be inclined downwardly and forwardly at a relatively acute angle and the galley shoot is made as short as is practicable in order that slugs stacked in the galley with the type faces uppermost may be readily inspected by the operator without removing them from the galley. The slugs are delivered from the mould 1 by an ejector blade 3 and pass between the trimming knives on to a shelf 6, upon which the slug is supported on its end with one side face against a wall 7. The wall 7 is pivoted at 10 so as to be movable laterally to push the slug sideways off the shelf 6 into the shoot, and normally the wall occupies the position shown in Fig. 3. Upon the advance of the mould wheel, a tappet 17 is pressed forward and swings a bell-crank lever 13 against the action of a spring 14 ; the lever 13 carries a link 12 pivoted to the wall 7 so that, upon the forward movement of the mould wheel, the wall is swung into the position shown in Fig. 1. As the mould wheel retreats, the wall 7 moves to the position shown in Fig. 3, and at the same time an extension on the bell-crank lever 13 projects through a slot in the wall 7 and engages the slug 5 so that the latter is both pushed forwardly and deflected laterally into the curved shoot 31, down which it drops by gravity, being guided throughout this movement by the curved shoot walls, such as the wall 20, which is adjustable with the trimming knife 2<a> to deal with slugs of different thickness. By this means, tipping of the slug is prevented. The usual slug stacker 24 is provided, operated by a lever 25, pivoted at 26 and moved by an arm 27 on the mould wheel support 28. The galley shoot may be straight and the wall 7 may be other than pivotally mounted. Specification 14582/90, [Class 100], is referred to.

Title: Electrical calculating circuits employing transistors
Inventor: WILLIAMS FREDERIC CALLAND
IPC: H03K19/084
Filed: 1952-07-28
Abstract: 748,546. Digital electric calculating-apparatus. NATIONAL RESEARCH DEVELOPMENT CORPORATION. July 13, 1953 [July 28, 1952], No. 19063/52. Class 106 (1). An adding circuit for producing " sum " and " carry digit signals in response to three binary digit signals A, B. and CD which are first combined to form a signal having four possible magnitudes, comprises an arrangement of transistors. The input signals A, B and CD are applied to the left-hand diodes of three double-diodes D6, D7; D8, D9 and D10, D11. A signal of - 2 volts represents binary " 0 " and +2 volts represents binary " 1 ". The effect of a binary " 1 " signal is to change over the 2 MA (one unit) of current flow from the lefthand to the right-hand diode of the doublediode concerned. One unit of current passing through the emitter El of transistor T1 will cause the transistor to trigger on in the manner described in Specification 747,606, " bottoming " on the knee of the characteristic curve, and an output signal will be obtainable at the point S. The changing over of two of the double-diodes provides two units of current at the common point P of the two emitters El, E2. Since the transistor T1 is unable to absorb this amount of current, the voltage at the point P rises by an amount sufficient to trigger the transistor T2, the point B2 of which moves from a potential of +1 volt, held by a diode D2, to a potential of - 1 volt, hold by a diode D3. This cuts-off the transistor T1 in which B1 is held at 0 volt by a diode D1. When signals appear on all three lines A, B and CD simultaneously, the three doublediodes D6, D7; D8, D9 and D10, D11 are changed over and the three units of current appearing at the point P is sufficient to cause both transistors T1 and T2 to be triggered on simultaneously. The output at C will normally be fed to the input CD of an adding circuit in the next higher denomination or through a delay circuit back to the lead CD shown. Means for bringing the output at C to the correct voltages for this purpose are described (Fig. 3, not shown).

Patent GB-906753-A (GB)
Title: Improvements in chucks
IPC: B23B31/18
Filed: 1961-05-26
Abstract: 906,753. Chucks. WOODWORTH CO., N. A. May 26, 1961 [June 2, 1960], No.19186/61. Class 83 (3). A chuck for gripping internally or externally comprises a plurality of rocker arms 28 each carrying (or each pair carrying) a jaw 112 at one end and engaged by means 86 at the other end for moving the jaw radially against a workpiece, the inner ends of the arms all being enclosed within a housing 14 which may form a lubricant chamber. The arms are mounted in a detachable housing plate 18 by integral or attached ball joints 42, and are operated by the toggle links 86 pivoted to a sleeve 90 moved by a draw-bar 104. A scale 126 indicates the toggle power-ratio and amount of jaw movement. Each jaw 112 is secured to its arm by a bayonettype joint 118, 119 and is secured tightly or with a degree of freedom by a screw 116. The degree of freedom to allow the jaw to accommodate itself to a workpiece is limited by a conicallyended screw 121 engaging a recess in the jaw. Since the jaws pivot slightly rearwardly as they are closed, the work is held firmly against end-stops 122 which locate the work and also act frictionally as work-drivers. The jaws can be reversed when the leading portion becomes worn or they may have separate gripping portions 161, Fig. 4, to adapt them to rough and finished work as they are reversed. The modified jaws 161 are mounted on flexible arms 165, Fig. 5, and the rocker arms 160, Fig. 4, are also flexible. The flexibility allows the toggles to lock overcentre. The jaws are operated by an air-operated piston 146. In a further modification, the toggle links 182, Fig. 6, have cam ends 184 engaging abutments 180 to cause the jaws 127b to grip the work as the draw-bar 104b is moved to the left against the force of return springs 198. Instead of pivoting the toggle links together, they may engage each other by teeth 202, 212, Fig. 7. For gripping workpiece 254, Fig. 10, by two sets of jaws 250, 252, the jaws are carried on bell-cranks 292, 294 and are moved to grip the work by springs 274 acting through pistons 266, 268. The pistons can be moved together by fluid-pressure to allow springs 300, 302 to open the jaws. In a final modification, a cover plate 322, Fig. 11, can be replaced by a plate having its ball-joints lying on a smaller circle so that smaller workpieces may be held.

Title: Combined electromagnetic and hydraulic dynamometer
IPC: H02K49/00
Filed: 1951-08-21
Abstract: 687,462. Hydraulic and electromagnetic brakes. SCHENCK MASCHINENFABRIK DARMSTADT GES., C. Aug. 21, 1951 [Aug. 28, 1950], No. 19724/51. Class 103 (i). [Also in Group XXXV] A dynamometer combines a hydraulic brake having a driving member 3 and a driven or braking member 4, which would normally be a stator, with an electric brake in which the member 4 acts as the rotor and carries an armature winding 6 braked by a fixed housing 7 carrying pole members 8. The unit may be made to operate as a hydraulic brake only by engaging a bolt 12 in one of the plates 5 of member 4. As an electro-hydraulic brake the electrical parts are excited and the hydraulic part is filled with fluid to the required degree. As an electro-dynamic brake only, the hydraulic parts act merely as a coupling between the shaft 1 and member 4. It is stated that depending on the excitation of the electrical parts, the rotor 4 can be made to rotate either in the same or reverse direction to the brake shaft 1. If it rotates in the reverse direction a relative rotation between members 3 and 4 of 1600 r.p.m. may be obtained with a speed of only 100 r.p.m. on the brake shaft. The range of regulation is therefore considerably extended at lower speeds. By supplying current, the electrical part may act as a motor for starting up an engine to be tested or when driven may supply current to a circuit. The member 4 may be arranged to be braked frictionally by a band-brake 20 operated from outside the housing as shown in Fig. 3.
