Title: Improvements in coin-freed mechanism
IPC: G07F11/18
Filed: 1925-10-17
Abstract: 261,526. Val Automatics, Ltd., and Cullimore, C. Oct. 17, 1925. Coin action, mechanical-connection; fraud, preventing.-A drawer or slide A is normally prevented from being pulled out over a stationary table B by a vertically - sliding catch G, controlled by a spring g<1> and adapted to engage abutment strips D on the underside of the drawer. A coin K inserted through a slot a' into a shoot C carried by the drawer, rests on pins H extending laterally from the catch and, when the drawer is pulled out, its upper edge engages an incline E on the underside of the table B so that it is depressed and thereby depresses the catch G out of the path of the strips D. After the drawer is pulled out sufficiently to release the catch, the coin is moved off the pins H and drops to a money-box. A member L carried by the shoot C extends under the catch G, when the drawer is locked, and prevents it from being depressed by the insertion of a wire or the like.

Abstract: 1470454 Optical range finding SOC DE FABRICATION D'INSTRUMENTS DE MESURE 12 June 1974 [29 June 1973] 25984/74 Heading H4D To determine the range D=MO<SP>1</SP> of a punctiform object M visibly contrasting with its background, two images I 1 , I 2  of the object are formed on the target 3 of a detector by means of an optical system arranged symmetrically around the perpendicular bisector 3<SP>1</SP>0<SP>1</SP>3 of the base line 0 1 0 2  and comprising a first pair of mirrors M1 and M2, inwardly directing the rays from the object towards the bisector 31013 and a second pair of mirrors M3, M4 receiving the directed rays and reflecting them through a focusing means 2. The distance D is related to the distance d between images by the formula where: f = focal length of means 2; D 1 = range for which d=0; L=length of base line. The distance d is determined by scanning the target of the detector (which may be a television camera) in a series of lines at right angles to the line X, X<SP>1</SP> joining the images, to produce a video signal having pulses when the images are encountered, the first pulse starting a counter and the second pulse stopping the counter, such that the count represents d. The Formula (1) is non-linear, but may be rendered linear by the intervention of optical deflecting means-e.g. prisms P 1 , P 2 -or by computer processing of the count.

Abstract: 706,834. Linear-dimension gauges. GLEASON WORKS. Oct. 16, 1952 [Oct. 17, 19511, No. 26021/52. Class 106 (2) An apparatus, Fig. 1, for rotating a test part D beneath the feeler of an indicator gauge 15 comprises a spindle 17, Fig. 2, for supporting the part D, radial thrust bearings 21, 22 and axial thrust bearings 27 for supporting the spindle 17, means 16 for rotating the spindle 17, and means 37 for moving the spindle 17 axially away from the axial thrust bearing 27. To avoid damage to the axial thrust bearing 27, the part D is applied to and removed from the spindle 17 only when the spindle 17 is displaced from the axial thrust bearing 27. A lamp 58, Fig. 1, may be lit automatically when such a displacement has been effected. The apparatus may include a power operated mechanism for tapping the parts D into position whilst they are being arranged on the spindle 17 with means for rendering said mechanism inoperative when the spindle 17 is engaged with the axial thrust bearing 27. The means 37 for causing a vertical displacement of the spindle 17 comprises a jack ring which normally rests on stationary bearing buttons 41. Fig. 6 shows a plane development of the jack ring 37 on the bearing buttons 41. When the jack ring 37 is rotated, cam lobes 42 on the bottom of the jack ring ride up on the buttons 41 to displace the jack ring to the position shown in broken lines in Fig. 6 and thereby lift the spindle 17 from its axial thrust bearing 27. By means of a lever 43, Fig. 1, the jack ring 37 may be coupled when desired to a ring gear 31, Fig. 2, meshing with a shank pinion 32 to which the hand wheel 16 is secured. The jack ring 37 may thus be turned through the desired amount by the hand wheel 16 to raise the spindle 17 from its thrust bearing 27. The apparatus includes means 66 for locking the spindle 17 against rotation, withdrawable means 57 for stopping the rotation of the jack ring 37 when it is resting on the buttons 41 and means for locking the lever 43 in position when in use.

Title: Improvements relating to electric signalling systems particularly telephone systems
IPC: H04Q1/446
Filed: 1929-08-28
Abstract: 335,035. Siemens Bros. & Co., Ltd., and Moore, A. T. C. Aug. 28, 1929. Exchange systems. - In a transmission system in which signalling is effected by alternating current of a frequency within the range (e.g. voice range) normally transmitted over the circuit, arrangements, controlled by a balanced alternating current bridge circuit coupled to the line, are made to nullify the effect of the frequency when received together with other frequencies. Signals received over the line L pass via amplifier A to a transformer, the secondary II of which comprises two equal impedances which form two arms of an alternating current bridge, the other arms consisting respectively of a resistance R and an inductance and capacity LC. LC is arranged to resonate at the signal frequency, at which frequency the bridge is balanced. When the signal frequency is received it passes via S to rectifying valve VS whence it energizes AR to light lamp SL. If frequencies other than the signal frequency arrive the bridge is unbalanced and a voltage will be impressed on the grid of valve VC producing a pulsating anode current in BT. This current is rectified by CR and so lowers the grid bias of VS that if the signal frequency is received with the other frequencies, the anode current of VS will be insufficient to energize AR. Condenser K delays the cessation of the control current during the reception of speech frequencies. To prevent disablement by supervisory tones of frequencies other than the signal frequency, break contacts x of the relay controlling supervisory tones may be inserted in the bridge balance circuit. Systems in which the bridge is connected directly to the line and in which the signal and control circuits (VS, VC) energize respectively (a) relays with make and break contacts in the circuit of SL and (b) opposing windings of a differential relay controlling SL are also described.

IPC: G11B3/095
Filed: 1947-09-30
Abstract: 643,680. Automatic gramophones. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Sept. 30, 1947, No. 26364. [Class 40 (ii)] In an automatic record-changing mechanism in which a member, which normally moves after a record has been played, may be obstructed by a spring-urged stop to cause repeat playing of a record, the stop is normally held out of obstructing position by a latch which may be released manually and is returned automatically. In Fig. 1, record-changing mechanism of the kind described in Specification 617,864 comprises a record-feeding sleeve 1 angularly movable by levers 4, 5, 6 under the control of a face-cam 2 co-operating with a pin 7, on lever 6, held against the cam by a spring 23. Normally at the end of the playing period cam 2 is rotated once by the driving motor (not shown) to oscillate sleeve 1 and feed a fresh record but release of a latch 12 at any time during playing of a record permits a bar 9 to move under the action of a spring, not shown, into the path of a pin 8 on lever 5 thereby preventing the oscillation of sleeve 1 so that the record is repeated. Release of latch 12, which is normally held against a lug 15 on bar 9 by a spring (not shown), may result from the operation of a mechanical or electrical push-button (not shown). A pin 17, rotated through gearing 3, 18 with cam 2, engages bar 9 and removes it from the path of pin 8 after initiation of record repetition so that bar 9 is re-latched and there is no further repetition unless the push-button is operated again.

Filed: 1946-09-04
Abstract: 654,631. Photographic material and processes. GEVAERT PHOTO - PRODUCTEN N.V. Sept. 4, 1946, No. 26570. Convention date, March 20, 1941. [Class 98 (ii)] Photographic material comprises at least two layers, one a light-sensitive silver halide emulsion layer and the other a receiving layer containing development nuclei or a substance capable of producing such nuclei. After processing, the emulsion layer is removed by melting, stripping, or chemical treatment, leaving a reversed image in the receiving layer. The substance incorporated in the receiving layer may be colloidal silver or silver nuclei, other colloidal metals, silver sulphide, sulphur, phosphorus, or sodium thiosulphate, and may be precipitated therein. A barrier layer, which may also serve as a stripping layer, may be disposed between the emulsion and receiving layers. The substance causing diffusion may be incorporated in the support. The barrier layer binder may be a hydrophilic colloid such as starch or methyl cellulose or a vary thin layer of hydrophilic colloid (e.g. nitrocellulose) which may be coated so as to dry porous. The emulsion may be untanned or contain additions such as ammonium carbonate or potassium thiocyanate preventing hardening. The emul. sion layer containing the negative image may be transferred to a glass support during stripping so that it may serve as a negative. In example 1, paper is coated with a composition containing gelatine, silver nitrate, and formaldehyde, and after thorough drying an untanned silver halide emulsion is coated thereon. A colour film diapositive may be printed on to the material, which is then developed in a developer containing hypo, squeegeed on to a glass plate, the emulsion layer washed off in warm water, and the transferred positive print toned in a selenium toning bath. In example 2, paper is coated with a composition containing gelatine, sodium sulphide, and silver nitrate, then with a gelatine-starch composition, and then with a contrasty silver halide emulsion. The procedure is as in example 1. Specifications 614,155 and 654,630 are referred to.
