Title: Improvements in or relating to coin freed vending machines
Inventor: DEAN HARRY
Filed: 1959-12-18
Abstract: 938,151. Testing coins in coin-freed apparatus. DEAN BROS. (ENGINEERS) Ltd. Aug. 25, 1960 [Dec. 18, 1959], No. 43190/59. Class 27. A coin-testing device for a vending machine comprises a pair of slightly spaced plates 1, 2 which are hinged together at the top and disposed in an inclined plane, and a separate testing member 4 which is formed with upper and lower coin-testing track surfaces 4d, 4e and mounted for close association with the stationary plate 1 and for movement away from this plate when the plate 2 is opened by a press-button or like control 7 to allow gravitational rejection of incorrect coins. The member 4 is mounted on the hinge pin 3 connecting the plates 1, 2 and extends into an inner recess in the plate 2. A channel-like recess 4a is provided in the member 4 bounded by the track surfaces 4d, 4e and continues below the track 4d as a thinner recess 4b. The width of the recesses is adjusted by a screw 5 in the member 4 bearing against the member 1. A second screw 6 is provided in the member 4 and projects into the recess 4a, and an aperture 1a provided in the member 1 registers with the recess 4a. The movable plate 2 is formed with an inclined lead-in 2c and a lower track 2d at the same level as the lower track 4d. In operation, an inserted coin may become jammed between the tracks 4d, 4e, fall into the recess 4b, stop against the screw 6, fall through the aperture 1a, or pass straight through depending whether the coin is respectively too large, too thin, too thick, too small or the correct coin. Coins which are stopped by the member 4 may be recovered by depressing a button or the like which, through the member 7, causes the plate 2 to swing away from the plate 1 and, after it has swung through a predetermined angle, acts upon an abutment 4c on the member 4 to cause the latter member to swing away from the plate 1, thus allowing the coin to fall into a rejection cup.

Abstract: 1469640 Collapsible trolleys R N SAXBY 13 Sept 1974 [14 Sept 1973] 43315/73 Heading B7B A trolley comprises end frames 12 and 48 and a bottom 30 which fold into adjacent planes when a handle 62 is pivoted in the direction of the arrow 84 about the top 14 of the end frame 12. The bottom 30 is pivotally mounted on a rod 20 which forms the bottom of the end frame 12. Links 66 and 68 connect the handles 62 to the bottom 30 so that the bottom swings up as the handle swings down. Side members 58 and 60 pivoted to the end frames ensure that the end frame 48 follows the bottom to a position against the end frame 12. A hollow bolt sliding within the handle 62 fits over a projection on the end frame 12 to lock the handle in the erect position. The trolley wheels are carried by square section members 96 which are pivotally mounted on the uprights of the end frame 12. When the trolley is erect, the wheels are held in position by the action on the members 96 of extensions 104 of the trolley bottom. As the trolley is collapsed, reaction with the ground swings the wheels about the frame uprights into a plane parallel with the end frame 12. As the trolley is erected, the extensions 104 exert a camming action on the square-section members 96 to swing the wheels back into their illustrated position. The trolley may be used in its illustrated form for the direct carriage of loads. Alternatively, a shopping bag can be slung from the frame 12 and may be large enough to contain the collapsed trolley. The trolley can support a golf bag or a baby seat having a folding frame.

IPC: G03C1/485
Abstract: 443,245. Photographic silver halide emulsions. GROVES, W. W., 30, Southampton Buildings, Chancery Lane, London.- (I. G. Farbenindustrie Akt.-Ges. ; Frankforton-Main, Germany) Aug. 27, 1934, No. 24644. [Class 98 (ii)) In the manufacture of emulsions which will yield direct positives by ordinary exposure in a camera or under a positive followed by development, the emulsion is exposed to the action of R÷ntgen rays before casting, preferably while molten and with vigorous stirring, until an emulsion layer formed from it, when developed without preliminary exposure, is blackened up to the apex of its gradation curve. Bromide, iodide, or iodo-bromide emulsions may be so treated. In an example, an emulsion is prepared by adding ammonium bromide and potassium iodide to a weak gelatin solution, mixing this rapidly with an ammoniacal solution of silver nitrate at 43‹ C., and ripening the emulsion at 45‹ C. Shredded gelatin is then stirred in, and the emulsion is digested and worked up in the usual manner. A layer of this emulsion 5 cm. thick is exposed for about 2 hours to X-radiation of defined character, and is thereafter cast. Specification 405,642 is referred to. Reference is also made to a known process of treating emulsion layers with R÷ntgen rays after they are coated and dried.

Filed: 1963-11-21
Abstract: 1,040,620. Photographic processing apparatus. OPTOMECHANISMS Inc. Nov. 21, 1963, No. 45949/63. Heading G2A. A photographic processing apparatus comprises at least two treatment stations, each having an inlet and outlet passage for processing fluid, a cover plate for the apparatus having an opening at each station into which openings respective pedestals project, a sealing gasket round each opening and standing slightly higher than the top surface of the pedestal, so that when a film is pressed face downwards against the gasket, the space between the film face and the pedestal forms a channel through which the processing fluid can be passed to act on the film. As shown, the film F receives a photographic exposure at A, and is then conveyed by sprockets S<SP>1</SP>, S<SP>2</SP> over the processing head 10, in intermittent frame-by-frame movement. The form shown has three processing stations 12, 13, 14 for developing, fixing, and washing respectively, formed as cavities in a base member 11. In each cavity is a pedestal (17, 18, 19) together with inlet means 22 and outlet means 23 for the respective fluids. Secured to the top surface of base 11 is a cover plate 39, having openings 41, 42, 43 therein, corresponding to the three processing stations. Each opening is provided with a gasket 50, which seals all joints between the cover plate and the base, and between the base and the pedestals. Each gasket also has two upstanding V-section ridges in rectangular configuration (51a, 51b), one within the other, surrounding the openings 41, 42, 43. The film F is traversed across the tops of these ridges, and is pressed against them by a spring-urged presser plate 65. The space between the underside of the film and the tops of the pedestals, determined by the height of the ridges 51a, 51b, forms an enclosure which is filled by the processing fluid as it flows from the inlet 22 to the outlet 23. At the first two stations, the fluid flows longitudinally of the film, and in a direction opposite to the film movement or feed, the ridges 51c, 51b also having a wiping effect on the film as it moves forward. At the third (washing) station, the fluid flows cross-wise of the film. The third pedestal 19 is of transparent material, with a lamp L below and a projection lens 63 above so that the image on the film may be visually inspected at this stage. If the times for developing and fixing are different, this may be allowed for by suitably proportioning the lengths of the processing stations, as in Figs. 9 and 10, (not shown) in which the developing station is 1<SP>1</SP>/ 2  times the length of the fixing station (the relative processing times being 3 seconds and 2 seconds).
