Title: Improvements in coin delivering apparatus
IPC: G07D1/00
Filed: 1932-03-31
Abstract: 403,935. Money-delivering apparatus. COINCHANGER VALENTIN & CO., 9, Vattugatan, Stockholm. March 31, 1932, No. 9314. Void [Abridged as open to inspection under Sect. 91 of the Acts, April 8, 1932]. [Class 116.] In a key-operated money-delivering apparatus, which may deliver change corresponding either to the value marked on a key or to the difference between this and a fixed value, each coin-ejector 20, Fig. 1, is linked to one of a series of rotatable rock-shafts 5-15 and the latter are rotated in combinations appropriate to the sum to be ejected by the corresponding key, by levers 38 which are linked at 39-41 to the key-levers 4. The coins are housed in removable tubes 23 contained in guides 202 provided with slots through which protrude the ejectors 20. Each of the latter has a coin-engaging head 21, a transverse guiding-member 24 and a notch 20a which engages a wall 201 of the guide 202 under the influence of a spring 26 when the coin-tube is removed, thus locking the keys. Each ejector is pivoted at 19 to a lever 17, itself pivoted at 16 and having a double extension, one portion 29 of which is connected to a returning-spring 31 and the other 30 of which is linked to the appropriate rocking-shaft of the series 5-15 which is divided into two sets by the shaft 3 on which the key-levers are pivoted. The key-levers may be linked to the upper set by the arrangement 38a, 44, shown in Fig. 3, and it is also stated that the connexion to the lower set may be varied ; the connexion of the key-lever to the appropriate link is in every case effected by means of a broad-headed pin operating within an elongated slot. The ejection slots are of adjustable height and are provided with U-shaped springs to prevent accidental ejection ; further, the shoot 28 and other parts with which the coins come into contact during ejection may be of perforated sheet-metal or of wire-net. The device may be housed in a cover having a roll-top 52.

Title: Improvements in electric impulse generator systems suitable for use in range-findingsystems
IPC: G01S7/28
Filed: 1940-05-28
Abstract: 582,360. Pulse generating circuits radiolocation. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., KEMP, R. J., and FEWINGS, D. J. May 28, 1940, No. 9363. [Class 40 (v)] In a range-finder of the radio reflection type with the transmitted and received impulses indicated on a cathode-ray tube, the impulse generator produces a first component followed by a second component of opposite sense as shown at WA, Fig. 2, the first being applied to a saw-tooth generator to control fly-back, and the second being applied either to the radio transmitter, or to a second impulse generator. The impulse WA is produced at the anode of a valve A of a multi-vibrator pair AB, Fig. 1. The grid leak ag of the valve A, and the condenser bc connecting the grid of A to the anode of B, are of considerably lower value than the other corresponding pair of elements. The later negative component of the impulse WA is applied by the lead LM to the radio transmitter and the earlier positive component to the grid of a valve C which in conjunction with a condenser CC and a resistance lr forms a relaxation oscillator for supplying time-base voltages WC to the cathode-ray tube indicator. These voltages are amplified and applied in opposite phase by the leads X, X<1>. At the anode of the valve B of the multi-vibrator, a negative pulse WB occurs at the same moment as the positive component at the anode of valve A. The pulse WB is used to extinguish the cathode ray during fly-back by applying it to the cylinder of the cathode-ray tube. The transmission of the radio impulse may be further delayed by applying the negative component of WA through a variable resistance to a second multi-vibrator similar to that shown in Fig. 1, thus producing a delayed double pulse similar to WA. The second or negative component of this delayed pulse is applied to the radio transmitter, Fig. 3 (not shown).
