Patent GB-1295204-A (GB)
IPC: G03B15/05
Filed: 1971-04-19
Abstract: 1295204 Control systems for flash apparatus FRANKE & HEIDECKE GmbH [trading as ROLLEI-WERKE FRANKE & HEIDECKE] 19 April 1971 [11 March 1970 13 March 1970 14 March 1970] 26893/71 Heading H2H Apparatus for producing a luminous flash in a gas discharge tube comprises a plurality of capacitors which are charged simultaneously together with switching means for sequentially discharging the capacitors into the discharge tube, the switching means being controlled by a photo-electric device responsive to reflected light so that only those capacitors necessary to produce a required flash intensity are discharged into the discharge tube. Capacitors 5, 6, 7 are charged simultaneously from a supply lead 8 by way of diodes 9, 10, 11 respectively, the capacitors then being discharged through a gas discharge tube 1 to produce a luminous discharge therein. The discharge is initiated by a trigger signal from the synchronizing contacts of a photographic apparatus, the trigger signal being applied to the starting electrode 2 of the tube 1 whereupon the capacitor 5 discharges through the tube by way of a diode 12. As the capacitor. 5 discharges, capacitors 15 and 17 are charging by way of capacitor 16 and resistor 19; and capacitor 18 and resistor 20 respectively, the time constants of these two circuits being different. Towards the end of the discharge of capacitor 5, capacitor 15 is charged sufficiently to break down a trigger diode 21 thus turning on a thyristor 13. Capacitor 6 now discharges through the tube 1 and near the end of its discharge a diode 22 breaks down turning on thyristor 14 so as to discharge the capacitor 7 through the tube 1. This action carries on for as many capacitors as 5, 6, 7 which may be provided. A photo-electric device is provided which is made responsive to the amount of light reflected from an object being illuminated by the tube 1. When the object has received sufficient illumination the photo-electric device produces a signal which when applied to a trigger electrode 4 of a glow tube 3-or a thyristor. The discharge current through the tube 3 causes a volt drop across resistors 27, 28 which render thyristors 25, 26 conductive so as to short circuit capacitors 15, 17, thus terminating the discharge of the capacitors 6, 7 through the tube 1. Various other embodiments are disclosed in which the reflected light is sensed by a phototransistor, the signal from which may be fed direct to the trigger electrodes of the thyristors 25, 26 or may be fed thereto by way of a transformer. In certain cases the glow tube 3 may be omitted.

As shown the stirrer shaft 17 is driven through cooperating serrated members 52, 57 which override when the viscosity of the mix rises. Freezing the mix causes the stirrer shaft assembly including members 52, 57 to rise and lift blade 50, to open switch 61. In alternative arrangements the blade 59 may be a bi-stable spring removed to the "off" position by the axial movement of element 57 or over-ride, and returned manually to the closed position; or the switch 61 may be a finger switch. The mixing container may be divided into compartments by a movable partition (10).

Abstract: 1310440 Contact printing frames OZALID CO Ltd 20 Dec 1971 [21 Dec 1970] 60583/70 Heading G2A A photo-copying machine comprises a cabinet 10 containing a light source e. g. fluorescent lamps 11, a plurality of flat bed vacuum printing frames 13, which can be individually slid from an initial preparation position into the cabinet for exposure, a timing mechanism 34 associated with each frame which controls means for retaining the frame in the cabinet for a preset time and then causing automatic return of the frame to its initial position and means for connecting each frame to a source of vacuum as it moves into the cabinet and disconnecting it from the vacuum source as it moves out of the cabinet. Each printing frame comprises a base plate 18, a transparent cover 19 and a resilient blanket 25 surrounded by a rubber sealing strip 24 which defines a suction channel 25. The channel 25 is connected to a suction duct 26 which is connected via a valve 27 and tube 28 to a vacuum reservoir 29. While the frame is at the preparation station A the valve is closed by a push-rod 30 co-operating with a fixed stop 31. As the frame moves into the cabinet along rails (14) the rod 30 is released, the valve opens under the influence of a spring and the vacuum pulls cover 19 on to the blanket 25. The vacuum also pulls down pins 22 which are provided for locating copy paper on the blanket. The timing mechanism energises a solenoid 35 which coacts with a core 36 mounted on the frame to retain the frame in the cabinet. After exposure the solenoid de-energizes and the frame returns to station A under the influence of a cable 15 and counterweight 17. In alternative embodiments the core is mounted on the cabinet together with the solenoid 35 and operates a latch to retain the frame. Also the rails (14) may be sloping so that after exposure the frame slides back to station A under gravity.

Abstract: 1349505 Ships' tanks MITSUI SHIPBUILDING & ENG CO Ltd 26 May 1972 24909/72 Heading B7A A tank 1 of a ship for carrying liquefied gas, of the type wherein the tank contains an unloading pump 7, is divided into sections interconnected by valves to facilitate the replacement of the liquefied gas and its vapour by fresh air in only one of the sections and thus to allow maintenance work to be carried out more quickly. In one embodiment (Fig. 2) the tank 1 is divided into a central section (I), an intermediate section (II) and an outer section (III). I and II are connectible by valves 33 and 36 and II and III by valves 52, 56. A liquefied gas main 4 and a vapour main 10, to which shore lines 24, 23 may be connected respectively, are connected to each section and the unloading pump 7 in I is able to unload liquefied gas from all three sections. Also connected to each section are lines from an inert gas inlet 21 and a fresh air inlet 22. If maintenance is to be done in I, the liquefied gas is unloaded from all three sections. III is now isolated from I and II and the vapour in I and II is replaced by inert gas. I and II are now isolated from each other and the inert gas in I is replaced by fresh air. Thus the vapour in III and the fresh air in I, which could together form a dangerous mixture, are separated by the inert gas in II. In another embodiment (Fig. 3), not shown, the tank is divided into only two sections. If work is to be done in one of them, they are isolated from each other and the vapour in one of the sections is replaced by inert gas which is then itself replaced by fresh air. The valves at top and bottom of the partition between the sections may be provided with additional series valves for safety in this case.

Title: Lining a tubular member with an elastomeric liner
Inventor: MCMILLAN JIM S
IPC: F16L55/165
Filed: 1992-01-21
Abstract: A method and apparatus are shown for lining a tubular member with an elastomeric liner having an outside diameter which is initially greater than the inside diameter of the tubular member. A series of downsizing rollers reduce the outside diameter of the liner a preselected amount. A series of shaping rollers form the downsized liner into an ellipse, thereby allowing the downsized liner to be guided around bends and turns into the interior of the tubular member. After insertion, the liner is allowed to expand to substantially its original outside diameter to secure the liner within the tubular member.

Title: Solid composition releasing chlorine dioxide
Inventor: MARZOUK YOSEF
IPC: A61L2/20
Filed: 1992-07-23
Abstract: A solid composition capable of releasing chlorine dioxide in water comprises (a) a water soluble chlorite salt, (b) an oxidizing chlorine-releasing agent in the form of sodium- and/or potassium- dichloro-s-triazinetrione(s) and/or trichloro-s-triazinetrione(s), and (c) a proton-donor serving as a water soluble agent capable of lowering the pH of an aqueous solution to less than 3. The chlorite salt (a) is advantageously a sodium or potassium salt. The proton-donor is advantageously sodium- and/or potassium-hydrogen sulphate(s) and/or pyrosulphate(s), or alternatively citric acid and/or malic acid. The stoichiomolecular ratio of the various components in the composition should be chlorite salt : oxidizing chlorine-releasing agent : proton-donor = 4 : 1 : 3, but a slight excess of the proton-donor may be advantageous. The solid compositions may safely be manufactured, stored and transported. Aqueous solutions in which the solid composition has been dissolved release chlorine dioxide quite quickly and almost quantitatively, and find use wherever chlorine dioxide is employed in industrial and water-treatment installations and processes. The solid compositions are also useful in antiseptic and sanitizing preparations.
