Title: An improved method and apparatus for continuously processing a web of photographic light-sensitive material
IPC: G03D5/00
Filed: 1962-02-08
Abstract: 990,183. Photographic processing apparatus. EASTMAN KODAK CO. Feb. 8,1962 [Feb. 8, 1961], No. 4861/62. Heading G2A. Light-sensitive material in strip form is processed by applying to it a layer of viscous developer, transporting it into a constant temperature developing zone, then into a zone where a fixing solution is applied, and then into a washing zone. In the form shown, the apparatus is housed in an upper cabinet 3 and a lower cabinet 11. The web 4 of photographic light-sensitive material passes into the upper cabinet through an opening 13, and is then carried over various rollers and guide members till it reaches a hopper 26. (The roller 16 is mounted on a vertically movable carrier 17, so as to maintain constant tension in the web as the length varies.) The hopper 16 contains the developer material in the form of a viscous liquid (produced by adding a thickening agent to a normal developer), and kept at 100F. by a water-jacket. This is applied to the full width of the web as it passes between the hopper and roller 27. The web now enters a developing chamber 28, maintained at 100F. by a hot-water jacket. The chamber is also maintained at 100% relative humidity, i.e. constant wet bulb temperature,by a jet humidifier 32 through which water at 100F. is sprayed. On leaving the developing chamber, the web passes through a hopper 37,where the developer is washed off by a spray 38. The stop solution is applied by allowing it to drip from a tube 40 down a sheet 42 of a flexible porous material such as fibreglass under which the web 4 passes. The bleaching and fixing mixture is similarly applied from a distributor 45 which drips it on to an endless belt 43 passing round rollers 44,the web passing downwards in contact with the belt, whose speed is about 25 times that of the web. The bleach-fix is washed off by water from a tube 48, and the web passes over roller 47 and down into the lower cabinet 11 for washing and drying. Here the web is conveyed in a looped path by a number of rollers 49, 51,the paths being separated by sets of endless belts 52. These belts are in contact with the web, and pick up washing water from a tank 54. After leaving the last wash belt, the web is treated with stabiliser by passing against a fibreglass screen 64, down which the stabiliser liquid runs from a distributor 65. After passing round a heated drying drum 9, the web leaves the cabinet over rollers 71, 72, and is finally wound on a take-up spool 69.

Title: Improvements relating to vacuum brake apparatus for railway and like vehicles
IPC: B60T13/46
Filed: 1924-02-28
Abstract: 234,196. Gresham, H. E., and Kiernan, G. Feb. 28, 1924. Valves controlled by pilot or relay values.-A vacuum regulating device for vacuum brake apparatus comprises the combination with the train pipe i of a main valve h and a pilot valve a both normally closed, the pilot valve being opened when the train pipe vacuum exceeds a predetermined maximum and admitting air to act upon a diaphragm or piston l whereby the main valve is opened or allowed to open to admit air to the train pipe through a filter screen k. The pilot valve is loaded by a weight b and communicates through a small bore d with the train pipe. When the vacuum in the latter becomes too high the pilot valve is lifted and air is admitted through a pilot o and chamber c to the lefthand side of diaphragm e the other side f of which is open to atmosphere via passage g and screen k. The diaphragm thereby moves to the right and the main valve lifts to supply air to the main pipe until the vacuum falls sufficiently to close the pilot valve. The small bore d prevents air passing direct from chamber c to the train pipe. In a modification the pilot valve is loaded by an adjustable spring, the diaphragm is replaced by a piston, and the construction is such that one air inlet serves for both valves.

Title: Improvements in railway trucks
IPC: B61F5/12
Filed: 1948-02-23
Abstract: 666,855. Rail-vehicle trucks; hydraulic shock-absorbers. GENERAL STEEL CASTINGS CORPORATION. Feb. 23, 1948 [Oct. 31, 1938], No. 5317/48. Class 103(vi) 'and 108(iii). A railway truck with wheels, axles, journal boxes, springs supported from the journal boxes, and a frame having wheel pieces supported by said springs, includes swing hangers suspended from the frame, springs supported by the swing hangers, a bolster supported on the last named springs, and a shock absorber at each side of the truck connected at its opposite ends directly to the bolster and to the adjacent portion of the truck frame, whereby the action of the bolster supporting springs due to violent and sudden vertical forces exerted between the frame and the bolster is checked. The truck frame comprises wheel pieces 6 slidably supporting, by means of springs 5, the axle boxes 3 and longitudinally spaced transverse transomes (not shown). Suspended from the transomes are pairs of pivotally mounted swing hangers 9 slotted at their lower extremities to support longitudinal bars 11 which in turn support transverse members 12. The extremities of the members 12 support coil springs 14 on which rest a bolster 15, metal to metal contact being prevented by rubber discs and rings 16 and A. Removal of certain parts of the truck is facilitated by the provision of a plate 17 having welded thereto a tube 18 and nut 19 to enable the spring 14 to be compressed by a bolt 20. The bolster ,15 is provided with arms 21 which extend downwardly and outwardly beneath the wheel pieces 6 and terminate in brackets 22 to support the inner element of a cylindrical hydraulic dashpot 24. The outer element of the dashpot is attached to a bracket 23 extended from the wheel pieces 6. In order to eliminate rolling caused by differential movement of the dampers on opposite sides of the truck, transverse torsion bars are mounted in bearings 32 on the wheel pieces 6 and are provided with cranked arms 33 pivotally connected by rubber bushes to the upper ends of links 34, of which the lower ends are pivoted to the arms 21. 'The Specification 'as open to inspection under Sect. 91 comprises also a description of the dashpot 24. The outer element 40 is attached to the bracket 23 by a rubbermounted rod which carries at its lower end a piston 42 over which slides the inner element 41 attached by a rubber mounting to the bracket 22. The piston 42 is formed with large ports 44 and smaller ports 45 of which the former are masked by a vertically floating disc 43 so that during downward movement of the bolster relative to the truck frame the disc 43 is thrust away from the piston 42 to permit relatively free sliding movement between the members 40, 41, whereas on the return stroke the disc 43 seats on the piston to close the ports 44 and create a damping effect by leaving the ports 45 only exposed. This subject-matter does not appear in the Specification as accepted.
