Title: Photographic exposure control
Inventor: POWELL FREDERICK WALLACE
IPC: G03B7/083
Filed: 1968-09-05
Abstract: 1,236,257. Photographic shutter exposure control. EASTMAN KODAK CO. Sept. 5, 1968 [Sept.5, 1967], No.42330/68. Heading G2A. A shutter is opened by energization of a coil L 1  and closed by de-energization of the coil, the exposure time being determined by the light energy incident upon photo-cell PC 1 . A capacitor C 4  is charged through resistor R 11  by depression of a switch S 4 , on release of the switch to its rest position the capacitor discharges through R 4 , R 5  to ground thus causing a potential rise on the gate electrode of silicon controlled rectifier SCR 1  which is turned on to energize the coil L 1  . At the same time a negative pulse is coupled through SCR 1  and capacitor C 5  to ensure that a second silicon controlled rectifier SCR 2  is turned off. The low anode voltage of SCR 1  is coupled through resistor R 7  to the base of a transistor Q 1  which is rendered non-conducting, and the potential on capacitor C 6  rises at a rate determined by the current through voltage divider R 25  and photo-cell PC 1 . After a time delay, the potential across the capacitor C 6  reaches the firing potential of uni-junction transistor UJT, which conducts and applies a positive potential through resistor R 23  to the gate electrode of rectifier SCR 2 . The firing of SCR 2  lowers the potential on capacitor C 5  and couples a negative pulse to the anode of SCR 1  which is switched off and de-energizes solenoid L, to terminate the exposure. The exposure control system is used in the exposure of high contrast photographic film in apparatus for copying line original documents.

A printing unit for use with a packaging machine is pivoted on the machine frame and comprises a horizontally reciprocable heated die block attached to a member 7 and mounted on a bracket 1 carrying a cylinder 9 containing a fluid-actuated piston, movement of the rod 8 of which actuates the die block and controls the feed of a printing foil 18, control means being provided for synchronizing the movement of the piston with intermittent movements of the packaging machine. The printing is effected on a bag of thermoplastic material formed on a tubular cylinder A before the bag is filled with free flowing goods and the engraved die block is heated by an electric cartridge element. Guide rods 12 which are secured to the member 7 to prevent its rotation, pass through a stationary plate 23 and carry a plate 24. A rod 26 is screwed into the plate 23 and passes through a tube 27 and carries lock stop nuts 29. The movement of the rods 12 is adjustable by altering the position of the nuts 29 or by the movement of plate 24 by adjustment of the nuts 25. The supply of fluid to the cylinder 9 is controlled by a five-port valve 30, the ports being operated in sequence by a control lever 34 actuated by a cam 35 on a shaft 36 driven from the main shaft of the packaging machine. Printing foils.-The foil 18 in the form of a pigmented film is drawn between the block and the bag from a spool 19 by rollers 20 and is then fed to a spool 37. An adjustable pivot on one rod 12 provides linear motion on reciprocation for a rod 15 connected to a lever 16 mounted on a clutch fixed to a feed spindle for the foil. The movement of the rods 12 is therefore adjusted according to the width of the legend on the dies so that the amount of foil drawn upwardly corresponds to that required for each printing operation.

Abstract: 961,841. Jet propulsion and direct lift of aircraft. BRISTOL SIDDELEY ENGINES Ltd., and S.I.A.I. MARCHETTI S.p.A. Dec. 20, 1961 [Dec. 21, 1960], No. 43974/60. Heading B7G. An aircraft comprises port and starboard gas turbine engines 14 with propulsion nozzles 20 supplied with air from the engine compressors and propulsion nozzles 23 supplied with turbine exhaust gases, the nozzles being adjustable to vary their discharge between a downward and a rearward direction, and has ducts 17, 18 for conveying air compressed by a starboard engine to a further nozzle 15 located outboard of a port engine, and air compressed by a port engine to a further nozzle (not shown) outboard of a starboard engine. Each engine, supported from its wing by a pylon, may have one or two air nozzles 20, and may be as described in Specification 881,662. The nozzles 15 may be adjustable with nozzles 20, 23, to discharge either in a rearward or a downward direction, and may include guide vanes as in Specification 910,693. Asymmetric thrust on failure of one engine is thus reduced, especially if fuel is burnt in combustors 16 just upstream of nozzles 15. Nozzles 20 and 23 may be rotatable to produce braking forces. Air for the ducts 17, 18 is tapped from the low pressure compressors of the engines 14, and these ducts may be simple cross-over ducts. As shown, however, these ducts extend from a pressure-equalizing chamber 39 fed from compressor bleed pipes 21 through valves 40, 41, each of which automatically closes when its associated engine fails. Valves 45a and 45b in ducts 18 and 17 are operable by a spring 48 on failure of pressure in engine bleed ducts 49, 50, so that when the starboard or port engine fails, the port or starboard nozzle 15 is isolated, respectively.
