Title: Improvements in or relating to coin freed vending machines
IPC: G07F11/24
Filed: 1928-09-14
Abstract: 319,139. Avery, Ltd., W. & T., and Bradley, L. C. Sept. 14. 1928. Delivery of articles stored in piles; filling storage receptacles.-Coin freed apparatus for vending articles of a cylindrical or other rounded shape in which the lowermost articles are supported on rotatable members operated by the weight of the asticles, have the members intergeared with a pinion and escapement wheel controlled by a lever adapted to be tripped to free the wheel by the inserted coin. Articles stored in the compartments 7 are supported by the rotatable members 13 mounted on spindles 14. Pinions 16, fixed to spindles 14, are intergeared with one another and drive a pinion 17 on a rotatable shaft 18 to which is fixed an escapement wheel 19. The notches 19<a> engage the end 20<a> of the arm 20 which is tilted to free the notches after the insertion of a coin. Thus, when the wheel 19 is freed the members 13 rotate owing to the weight of the column of articles until the end 20<a> engages the next notch 19<a>. 'The members 13 are arranged to deliver one article at a time, and in a modification, can be fixed on independent common spindles. The casings 8 are hinged to give access to the compartments 7 for recharging. Coin action, weight.-A coin inserted in the chute 22, after passing a testing device, falls on to the arm 20b of the detent 20 to disengage the escapement wheel 19 after which it falls into the cash box. Coin-slit closing-devices.-The extensions 23<a> of the arms 23 depend into the cut away sections 7<b> of the casing and tend to project through the compartment 7 under the influence of the counterweights 24. The arms 23, interconnected by a common linkage, co-operate with a lever 25a and a rod 25 the upper end of which is attached to a cover plate. When a compartment 7 is empty the extension 23, urged by the weight 24, enters and the cover plate is moved to cover the coin chute.

Title: Improvements in or relating to distribution means for hydraulic gears
IPC: F16H61/40
Filed: 1936-09-29
Abstract: 482,309. Hydraulic gears ; fluidactuated valves. HEERDT, O., and PITTLER WERKZEUGMASCHINENFABRIK AKT.-GES. Sept. 29, 1936, No. 26435. [Classes 69 (ii) and 135] A valve device for use with hydraulic gears comprising a reversible pump part and a motor part is arranged between two pipes connecting the pump to the motor and a third pipe connected to the reservoir, and is so arranged that, whichever connecting pipe is under pressure, the pressure closes the valve between that pipe and the third pipe and opens the valve connecting the third pipe to the return connection between motor and pump. In the form shown in Fig. 1, the two connecting pipes 2, 3 lead to chambers housing opposed lift valve members 5, 6 biassed towards their seats by springs 15. The valves are guided by fluted guides 7, 8 sliding in the casing, which guides are bored to form cylinders housing abutting plungers 9, 10 each subject on its outer face to the pressures existing in the conduits 2, 3. When for example the conduit 3 is under pressure the valve 6 is held against its seat while pressure admitted through passage 14 acts on the plunger 10 which in turn acts on the plunger 9 to open the valve 5, so connecting the passages 2 and 4. In the system shown in Fig. 2, the two connecting conduits adjacent the pump are connected through a valve device 1 as described above and a conduit 4 with an oil reservoir B while the conduits adjacent the motor are connected with the oil reservoir through a similar valve device 1<1>. Oil is supplied to the pump through one or other of the valves in the first mentioned valve device and is returned in part to the reservoir, after passing the motor, through one or other of the valves of the second valve device. The other part of the return flow returns direct to the main pump. In a modification non- return ball valves are inserted in the conduits to cause the whole of the return flow to pass to the reservoir. An auxiliary pump 19 connected to the conduits 2, 3 through non- return valves 30, 31 supplies oil to the hydraulic circuit to ensure the presence of sufficient oil to lubricate the pump P when it is rotating without delivering oil. The system is fitted with relief valves at various points discharging into the reservoir.

Title: Improvements in automatic slack adjusters for vehicle brake rigging
IPC: B61H15/00
Filed: 1952-10-22
Abstract: 702,447. Brake slack adjusters. SVENSKA AKTIEBOLAGET BROMSREGULATOR. Oct. 22, 1952 [Oct. 22, 1951], No. 26555/52. Class 103(1) In an automatic slack adjusting mechanism for rail vehicle brake rigging of the type comprising a two part rod made up of members 2 and 3 linked at each end to the brake rigging and normally fixed in length by means of coupling and feed or adjusting nuts 5 and 8, but releaseable on excessive slack in the rigging by the action of collar 23 on rod 24 engaging an arm 31, so as to move the tubular casing member 9 thus compressing spring 15 and freeing the coupling nut 15 for rotation on the quick pitch threaded rod 3, special provision is made to. permit the length of the twopart rod to be manually adjusted when in released condition. The hand adjustment mechanism comprises an arm 29 that may be rocked to and fro by handle bars 30 accessible at each side of the vehicle so as to rotate a sleeve 27 coaxial with the tubular rod 2. A coiled spring 25 provides a one-way clutch device between sleeve 27 and end piece 14 so that reciprocatory movement of the handle bars 30 produces a uni-directional rotation of casing 9 which through end piece 11 and its friction seat 10 causes a rotation of the feed nut 8 to adjust the length of the two-part rod. So that the rod may not be unintentionally adjusted by rotation of casing 9 by service shocks or vibrations the spring 9 is arranged to seat directly on end member 14 to provide torsional resistance. Two modifications in which the coupling nut 5 is largely relieved of the force transmitted from spring 15 on to member 9 are described.

Abstract: 1434766 Semiconductor devices; printed circuits WESTINGHOUSE ELECTRIC CORP 5 June 1973 [20 June 1972] 26664/73 Headings H1K and H1R A method of producing a high resolution mask on a substrate 10, e.g. a semiconductor wafer or a GRP circuit board, includes: defining thereon a desired pattern in a radiation sensitive layer 12, preferably by using an electron beam and removing irradiated layer parts; depositing a layer 17 of etchable material on layer 12 and the exposed substrate surface 15, followed by the deposition of an etch resistant layer 18 on layer 17 Fig. 3; dissolving layer 12 and thereby removing the parts of layers 17 and 18 thereon; partially etching the remaining layer part 17<SP>1</SP> to form a pedestal structure, Fig. 5; depositing a third layer 21 of etchresistant material, over the exposed substrate surface and the layer 18<SP>1</SP>, Fig. 6; and finally etching the layer 17<SP>1</SP> and thereby removing overlying layers 18<SP>1</SP> and 21<SP>1</SP> to leave a pattern accurately defined in layer 21 on the substrate, Fig. 8. The layer 17 may be of aluminium, silver, gold, platinum, nickel, palladium, tungsten or silicon and may be deposited by evaporation or sputtering. Layer 18 may be of titanium or chromium, deposited by evaporation or sputtering, and is oxidized following deposition to enhance etch resistence and prevent the formation of an electrical couple with layer 17 during etching. Layer 21 may also be of titanium deposited by evaporation or sputtering and is also oxidized to aid etching accuracy. In an alternative method, layer 17 is deposited on the substrate, the radiation sensitive layer being formed thereover, the manufacturing steps following deposition of layer 18 and removal of layer 12 being similar to those above. The pattern eventually formed in layer 21 may be covered with photo-cathode material, e.g. palladium, gold, platinum, aluminium, barium, copper or cesium iodide to produce an electromask for subsequent component forming operations.

Abstract: 444,579. Roads ; brushing- machines. FEDI, J. A. H., 12, Rue Abel, Paris. Sept. 20, 1934, No. 27078. Convention date, Sept. 21, 1933. [Class 107] Concrete roads containing large stone aggregate are given a roughened surface by ramming or packing the concrete to bring the stones into close contact, then rolling it to provide a smooth surface in which the stones are exposed, and finally, when the cement has set but before it has completely hardened, treating the surface by means of a brushing machine adapted to remove the cement from between the stones. The machine employed preferably comprises one or more plane circular brushes each mounted on a vertical shaft which can be adjusted to vary the pressure of the brushes upon the road surface. The brush bristles may be of metal or piassava. In operation, the machine is moved to and-fro until sufficient cement has been removed from the road surface. The Specification as open to inspection under Sect. 91 describes one form of brushing machine suitable for the purpose. As shown, the brush shafts 11 and the machine itself are driven by a motor 4 mounted on the machine frame 1. The transmission gear to the brush shafts consists of bevel wheels 9, 10, a horizontal shaft 7, and a helical gear 12. The brush shafts are urged downwards by springs 28 and are journalled at 7a and 7b in a small platform 30 which is hinged at 31 to the frame 1. This platform is normally secured to the frame 1 by a locking device 32, 33, which can be readily released to enable the platform to be swung upwards when access to the brushes 29 is desired. Theadjusting mechanism for the brushes consists of a bifurcated hand lever 23 the limbs of which are pivoted to brackets 24 on the platform 30 and the free end of which carries a looking member engaging with a fixed quadrant 25. Each limb carries a rotatable screwed shaft 18 operated by a hand wheel 20 and each shaft carries a nut 18a connected to the free end of a lever 15 pivoted at 16 to uprights which carry the bearings 7a. The levers 15 have pin-and-slot connections with collars on the shafts 11. In operation, the shafts 11 are raised and lowered individually by means of the hand-wheels 20 and simultaneously by the hand lever 23.
