Title: Coin or token testing system
Inventor: DENNESS ANTHONY CHARLES
IPC: G07D5/00
Filed: 1967-07-17
Abstract: 1,246,622. Coin testing. MARS Inc. 17 July, 1968 [17 July, 1967; 19 Feb., 1968; 15 June, 1968], Nos. 32672/67, 7967/68 and 28608/68. Heading G4V. A coin or token to be tested passes down a runway 19 to actuate a photo-electric transistor 27 applying a signal to a circuit determining whether the time taken by the coin to pass the photo-electric transistor lies within predetermined limits. A coin inserted in shoot 14<SP>1</SP> falls past a magnet 20 (which retains ferromagnetic coins until manually released to fall to the bottom of the device) on to the runway 19 where it is held by a catch 23 and actuates a photo-electric transistor 26 releasing the catch after a predetermined delay. A magnet 28 induces eddy currents in non-ferrous coins as they roll down the runway to brake them. Outputs from photo-electric transistors 26, 27 trigger monostable circuits 37, 38 and 39, 40, respectively, providing outputs the duration of which correspond to the upper and lower time limits for genuine coins to travel between the photo-electric transistors 26, 27 and pass photoelectric transistor 27 alone. The outputs from the monostable circuits and the photo-electric transistor 27 are applied to coincidence gates 41-44 energizing memory circuits 45-48 if the times taken lie within the aforementioned limits. Three identical circuits are provided for penny, threepenny and sixpenny pieces, the outputs from the circuits energizing corresponding counters 50-53 and acceptance solenoid 29 withdrawing guide track 30 to deposit a genuine coin in a coin box. In an alternative embodiment, Fig. 4 (not shown), an inserted coin is deflected against wall (63) by pin (62) whereby the coin starts down an inclined track (61) from rest. A magnet (64) slows coins of acceptable resistivity so that they fall into a vertical shoot (65) past a photo-electric transistor (67) and on to a vertically displaceable anvil (68) connected to a transducer (69). The displacement of the anvil and the time taken by the coin to pass the photo-electric transistor are compared with standards characteristic of genuine coins by means of circuits identical to those of Fig. 3 except in that the signal from the transducer (69) alone is passed to a bi-stable circuit (76) which provides a signal corresponding to the duration of displacement of anvil (68). Clearing apparatus.-The apparatus may be cleared of a ferromagnetic coin &c., retained by magnet 20 by hinging front member 14 away from back member 12 about pin (16), Fig. 2 (not shown), magnet 20 being moved away from back member 12 by lug 22 on front member 14 engaging with the end of pivoted magnet mounting lever 21.

Title: Automatic jack device for automobiles
IPC: B60S9/04
Filed: 1938-10-03
Abstract: 506,319. Jacking-appliances on vehicles. MINICONI, H. J. Oct. 3, 1938, No. 28667. [Class 79 (iii)] A pivoted segment 1, adapted on engagement with the ground to be rocked to raise a vehicle wheel by slight rearward movement of the vehicle, is normally maintained by yielding -locking means, such as a spring-pressed bolt 8, Fig. 5, in the inoperative' position shown in which it is clear of the ground whilst the tyre is inflated but engages the ground on deflation, being then responsive to rearward movement of the vehicle to raise the wheel. The bolt 8, carried by the supporting bracket 4 clamped to the axle, is pressed into a V-shaped recess 10 in the face of the hub 7 of the segment, yielding to the movement of the vehicle when the segment is in engagement with the ground and serving to restore the segment to its inoperative position when the segment is thrown back by forward movement of the vehicle after tyre or wheel replacement. The segment, which is of metal, is formed with peripheral serrations and a reinforcing bulge 6.

Abstract: 1,073,776. Heatingand cooling buildings; air conditioning. SULZER BROS. (LONDON) Ltd. July 15, 1964 [July 19, 1963; May 1, 1964], Nos. 28777/63 and 18241/64. Headings F4U and F4V. [Also in Division F2] In an air-conditioning unit a heat exchanger 90 for heating or cooling the air has an inlet which is connectable selectively to a heating fluid supply pipe 86 or to a cooling fluid supply pipe 82 by means of a valve 88 controlled by a thermostat sensitive to local air temperature, and an outlet which is connectable selectively to a heating fluid return pipe 87 or to a cooling fluid return pipe 83 by means of a valve 89 controlled by a thermostat sensitive to the temperature of the fluid leaving the heat exchanger. As shown, the heating and cooling fluid is water circulated by pumps 85, 81 through a heater 84 and a cooler 80. The valves 88, 89 have a lost motion connection between the valve elements and the thermostats so that at a certain air temperature the valve 88 will close both supply pipes, and at a certain temperature of fluid leaving the heat exchanger 90 both return pipes will be open. In this condition the quantity of liquid circulating in each circuit is maintained approximately equal by balance tanks 92, 93 connected to the return pipes so that an increase in the liquid level in one tank, and hence in back pressure is caused by an increase in fluid quantity in either circuit. An overflow connection 94 prevents excessive build-up of back pressure in either circuit and float-operated valves 95 admit make-up water. The air may pass through air filters, humidifiers or de-humidifiers 97, 98, 99 before being blown by a fan 96 over the heat exchanger 90 to be heated or cooled before passing into a room.

Title: Improvements in the process of producing compound sheets or plates of glass and celluloid
Filed: 1926-11-15
Abstract: 261,425. M³hlig-Union Glass-Works Co., Ltd. Nov. 16,1925, [Convention date]. Compound sheets.-Relates to the production of compound plates of glass and celluloid by treating one or more sheets of celluloid with a solvent such as alcohol, acetone, or amyl acetate, and uniting them with glass plates by pressure. According to the invention, before treatment with the solvent, both sides of the celluloid are prepared, by coating or rubbing, with a substance which penetrates only slowly or sparingly into the celluloid and prevents excessive absorption of the solvent. Substances suitable for this purpose are esters obtained from glycerine and the lower fatty acids, (e.g. triacetin), esters obtained from the higher fatty acids and the lower alcohols, (e.g. methyl or ethyl oleate), and the higher alcohols used alone. The esters used need not be chemically pure. The glass plates or celluloid sheets may be coloured or patterned.

Title: Scutching machine for automatically scutching bast fibres
IPC: D01B1/30
Filed: 1927-10-29
Abstract: 280,198. Etrich, I. Nov. 8, 1926, [Convention date]. Breaking and scutching apparatus; grip-chain and like arrangements for feeding, holding, and conveying fibrous materials.-In a machine for treating bast fibres, such as flax, in which the material is held centrally by a pair of feed bands and is moved past a pair of scutching-devices, which treat one end, and is then transferred to a second pair of bands, which are slightly displaced laterally, and is moved past a second pair of scutching-devices, which treat the other end, the pairs of feed bands are pressed one against the other by a pneumatic device. The pairs of feed bands 3, 4, Fig. 6, are of rubber, leather, &c. and are grooved and ribbed to fit one another. The lower band 4 runs in a groove 24 in the frame. The upper band 3 is guided in the frame 25 and is pressed against the band 4 by a series of rollers 26, mounted in pairs in frames 27 so as to be capable of vertical movement. A pneumatic tube 28 is accommodated in the frame 25 and supplied with air under pressure to grip the material between the bands. The rotating scutching-devices operate in pairs and comprise blades mounted on radial arms 10, Fig. 4. Perforated shields 37 are carried by the arms to prevent the fibre winding round the blades. The blades are reduced at the ends and secured to a disc 35, which embraces a flanged ring 36 fixed in the frame to prevent fibres wrapping round the bearing of the shaft 8. The outer face of the flange lies flush with the outer face of the disc 35. The material is fed transversely by a series of rollers 1, Fig. 1, on to the feed table 2 and is moved into the grip of the bauds 3, 4 which carry the material past the scutching-devices 5, 6. The material is then passed to a second pair of bands 11, 12 and carried past the scutching devices 13, 14. At the changing point the pulleys carrying the pairs of bands are mounted coaxially and are spaced apart laterallv. A blast of air from a nozzle 34 may keep the material straight as it passes from one pair of bands to the other.

Abstract: 1311303 Fluid-pressure servomotor systems BARRY WRIGHT CORP 15 June 1970 [16 June 1969] 28937/70 Heading G3P Pressure-responsive pneumatic means for adjustably supporting a platform 14, Fig.1, includes a sensor 86 responsive to deviations in the position of the platform, a valve 44 operable by the sensor for conducting pneumatic fluid from a pressurized source 45, Fig. 4, to the pneumatic means, and a pressure regulator 63 to maintain a constant difference in pressure between the pressure acting on the pneumatic means and the pressure of the conducted fluid from the source. The table is mounted on four legs 11 each having anairspring 21 comprising a plunger 26 enclosed by a cup shaped diaphragm 25 in a cylinder 22 communicating through an adjustable needle valve 42 with a damping chamber 43. A port 47 in the valve 44 is connected to the inlets 37 of the air springs, and through a passage 78 with an adjustably spring-loaded piston 67 of the pressure regulator 63 which controls communication between the pressurized source 45 and an intermediate pressure chamber 56 separated from the source by a spring-loaded valve 53 opened only by abnormal downward movement of the platform. Normal downward deviation causes a tube 81 to open a second spring- loaded valve 57 so that air is supplied from the intermediate chamber 56 to the springs and to the intermediate chamber through the regulator 63. An upward deviation separates the lower end of the tube 81 from the valve 57 and connects the air springs to a vent 48 through the tube bore 88 and a radial hole 84. To prevent undesirable build up of pressure in the chamber 56 a bleed hole 60 on a valve seat of predetermined roughness is provided. The sensor 86 is made from music wire or a filament of stainless steel to accommodate any lateral deviation of the table.

Class 93 [Also in Group VIII] Decorated synthetic resin objects are made by colour-printing on cellulosic paper that has been impregnated to give high wet-strength, impregnating the printed paper with a thermosetting synthetic resin and at the same time removing any air contained in the paper, partly condensing the resin, supplying moisture, e.g. as water vapour, to remove brittleness resulting from the condensation, placing the paper with its printed side in contact with further partly condensed thermosetting synthetic resin material, and hot-pressing the assembly., The wet-strength impregnant may be degraded starch, or a melamine resin which may be added as a powder or an aqueous solution to the pulp from which the paper is made, and dried or partly condensed on the paper. Aluminium powder or fibres may be incorporated in the paper. The paper may be heated by a high frequency field after printing. The impregnant for the printed paper which may be phenol-, urea-, or melamineformaldehyde, is applied by immersing the paper in the impregnant in a cointainer in which vacuum and pressure are produced alternately. The resin-impregnated paper may be creped before drying. A condensation catalyst, e.g. formic acid, may be added to the water vapour used for re-moistening the dried, resin-impregnated paper. The colouring matter should be free from fat in order that it may not repel the subsequently applied resin,
