Title: Improvements in or relating to coin separators
Inventor: HAVERSTICK MERRAL P
IPC: G07D3/14
Filed: 1953-10-19
Abstract: 738,244. Testing and sorting coins in coinfreed apparatus. NATIONAL REJECTORS, Inc. Oct. 19, 1953, No. 28788/53. Class 27. A coin separator tests the weight, diameter, peripheral configuration, thickness and electrical conductivity of coins and is particularly adapted to test a special serrated or toothed coin 104 by means of a toothed runway 22 along which the coin rolls past the field of a permanent magnet 32. Coins inserted at 94 are first tested by spaced lugs on a pivoted counterweighted cradle (not shown) and larger coins of proper weight and size are directed to a runway (not shown) where they are tested for electrical conductivity by a permanent magnet 106. Smaller coins pass through the lugs and are directed by a surface 98 into a passageway between the separator frame 10 and a hinged wall 16, where oversized coins are held up by a projection 19 appropriately spaced from the frame. Below the projection 19, a feeler pin 28 on an elongated spring 26 is pressed aside by a coin of proper weight but if the coin has a hole or pronounced surface deformation the feeler will hold it up. The feeler pin also acts on coins which, while resting at the top of the runway 22 fixed to the hinged wall 16, are too small for their top edge to rest against the top edge of an opening 54 and ejects them to a reject shoot 53. A coin that has passed the initial tests will start rolling down the runway 22 but, if it does not have teeth at its periphery, it will ride on the points of the runway teeth and be held up by the end of a scavenging lever 58 or, if it is too thick, it will not enter the narrow passageway between the frame and the magnet 32. If the coin does not have the correct number of teeth of the correct size and configuration or if it does not have the required electrical conductivity, it will either not roll along the runway or its speed will be such that it will fall, either directly or by rebounding from a stop 101, on to the right hand side 38 of a divider having a hinged part 40 at its apex and thence into a reject shoot 52. The speed of correct coins will be such that they fall to the right of the divider, into an accepted shoot 50. Clearing apparatus. Any coins held up in the separator are cleared by depressing a pressure plate 66 so that the scavenging lever 58 is rotated counter-clockwise by a bar 74 pivoted on the plate, the wall 16 is rotated on its pivot 14 by a lever 84 having a roller 86 bearing on a cam plate 78 on the bar 74 and a wall 92 is rotated on its pivot 90 by a pin 97 on the pressure plate engaging a cam surface 96. Tokens of special form. The special coin 104 has teeth in the form of a gear and is chamfered to prevent the edges of the teeth catching on the upper edge of the opening 54 as the coin rolls along the runway 22. The value represented by the coin may be in excess of the value of coins in general circulation, in order to avoid the necessity. for the insertion of a large number of coins when vending higher-priced articles.

Title: Improvements in or relating to television systems
IPC: H04N11/18
Filed: 1954-10-06
Abstract: 773,078. Television. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Oct. 6, 1954 [Oct. 8, 1953], No. 28790/54. Drawings to Specification. Class 40 (3). In a " compatible " colour television system successive lines are transmitted in one of three component colours and simultaneously therewith in alternate ones of the other two colours. As described, the " blue " signals of successive lines are transmitted with a band width of 200 to 300 kc/s. on an auxiliary carrier (and may be multiplexed with accompanying sound signals) and the " red " and " green " signals, which occupy a band width equal to that required for black/white reproduction, are transmitted alternately on a main carrier, each for the duration of a single line. At a colour receiver the " red " and " green " signals are supplied alternately to suitable colour imagereproducing devices (e.g. separate red and green colour tubes or a single dichromatic tube or to two " guns " of a tri-gun three-colour tube) and the " blue " signals to a separate " blue " colour tube (or to the third gun of the threecolour tube) the images being optically combined when separate tubes are employed and colour filters interposed in the optical paths if tubes producing monochromatic images are employed. At a black/white receiver (which is tuned to the frequency of the main carrier) the " red " and " green " signals are effective to produce a monochromatic image. The alternately transmitted signals may correspond to images of a " stereoscopicpair" or to different and unrelated pictures, the receivers in either case being suitably modified.

Abstract: 391,144. Gaseous mixtures; gas producers. POWER-GAS CORPORATION, Ltd., RAMBUSH, N. E., and GRISENTHWAITE, A. T., Parkfield Works, Stocktonon-Tees. Oct. 17, 1931, No. 28887. [Classes 55 (i) and 55 (ii).] A gaseous fuel for use in heating retorts, or for distribution, is obtained by mixing with distillation gas a poor gas containing a larger proportion of carbon monoxide to hydrogen than water gas, and of lower calorific value. The poor gas may be obtained by using the " blow " gases produced towards the end of the blow period in a water-gas generator, or by adding air to the steam during the steaming period, or by adding steam to the air during the part of the blow when the air is supplied at a relatively low rate. Water gas may also be added to the gaseous mixture. A large main may be used for the blow proper, and a smaller one for the producer gas blow. More than one water-gas unit may be employed to obtain a constant supply of the poor gas necessary. A gas producer suitable for use in the process is described in Specification 353,522.

Abstract: 983,530. Rolling gear teeth. KENT-OWENS MACHINE CO. July 23, 1963, No. 29184/63. Heading B3M. A method of forming a gear-tooth on a region of a gear-blank comprises supporting the blank and repeatedly rocking a cam-shaped, profiled, tooth-forming tool across the blank, the tool performing a rolling motion. A gear-blank 50, to be rolled by a tool head 18, is mounted in a frame 12 which is vertically movable in guides 14. The head 18, which supports a number of planetary tools 80, is driven by a motor 20 about a shaft 16, the motor also driving gearing to give rotational and vertical indexing of the workpiece. The blank is given intermittent rotation by a bevel gear 26, driven from the shaft 16 by a chain 24, a Geneva dog 30 and star-wheel 32, Fig. 2, bevel gears 40 and 42, and a shaft 46. Similarly, a clutch 60, which is engageable with either of bevel gears 54 or 56, both of which engage with an internally screwed nut 62, produces intermittent upward and downward movement of the frame 12 holding the workpiece. Variations in the feeding motions can be made by suitably altering the gear ratios in the gear trains. Each tool 80, Figs. 3, 4, is mounted on a shaft 78 which is rotated about the spindle 16 and also about its own axis by the co-operation of a planetary gear 76 with an internally toothed fixed ring 74. The working surface 86 of each tool is arcuate, the centre of radius of the arc being between the axis of the shaft 16 and the shaft 84. In the above system the blank is fed upwardly after each contact of a tool with the workpiece, but, if desired, the blank can be fed upwardly after each complete rotation of the blank. This is effected by a pneumatically operated piston which causes a partial rotation of the screw 64, by means of a ratchet driven worm-wheel, at every revolution of the gear 42, the gear 42 being supplied with a detent which trips the pneumatic circuit (Fig. 8, not shown). The travel of the piston can be controlled by a profiled cam to alter the rate of feed during the working of a blank. In place of rotating tools 80, oscillating tools of a tapered sectarial form may be used, the position at which the tool contacts the workpiece, during oscillation of the tool, being adjustable to give compensation for wear in the tool.
