Title: Improvements in and relating to photographic cameras and flashlight apparatus
IPC: F21K5/12
Filed: 1966-09-01
Abstract: 1,140,137. Photographic flash apparatus. AGFA - GEVAERT A. G. Sept. 1, 1966 [Sept. 2, 1965], No. 39126/66. Heading G2A. An electrical flashlight apparatus, for attachment to or inclusion in a photographic camera, comprises a plurality of rotatable sockets for a corresponding number of flash cubes, the mechanical and electrical arrangements being such that only one flash cube at a time is included in the ignition circuit, complete use of one flash cube automatically switching in the next flash cube until all the flash cubes have been used. A manual override is provided to allow of more than one flashbulb being fired simultaneously. The cubes are either all rejected manually, or else each cube is automatically ejected when it has been fully used. As shown, flash cubes 4, 5 fit into cruciform apertures in wheels 37 in a camera housing. Insertion of the flash cubes depresses ejectors 39 and compresses springs 41, the ejectors being depressed sufficiently so that by slight rotation of the cubes, lugs 39c, 39c' engage annular surfaces adjacent recesses 43. A spring 48 pushes up a clutch plate 49 and prevents further manual rotation of the cube 4 which is rotated by the plate 49 with each film advance. During the fourth film advance, the lug 39c is again aligned with the recess 43 and the spring 41 raises the ejector 39 to eject the cube 4. Upward movement of the ejector 39 causes a spring 48' to push up a clutch plate 49' and a push rod 51, an arm 54 of which changes over a switch 55 to switch the cube 5 into the ignition circuit, the cube 5 now being held against manual rotation by the plate 49'. Cube 5 will similarly be automatically ejected after four further exposures. Assuming there is still an available bulb in the cube 4, if an exposure is required to be made using two flash bulbs, a lever 51a is rotated through 90 degrees clockwise (as seen), to close a switch 56 to bring the cube 5 into the ignition circuit also. In another embodiment Figs. 1-3 (not shown), the apparatus comprises a housing (1) having an attachment foot (8) to attach the apparatus to a camera. Either of two flash cubes (4), (5) is rotated by a friction wheel drive (12), (13) and reduction gearing (9-11), the drive being coupled to the film advancing mechanism of the camera concerned. As before, two bulbs may be fired simultaneously. In a further embodiment Figs. 4, 5 (not shown), the apparatus accommodates three flash cubes (33-35) each positioned on rotatable wheels (24-26) which are driven by an endless belt (27), which in turn is manually driven.

IPC: G01L11/00
Filed: 1957-12-17
Abstract: 842,037. Pressure gauges. VICTORY ENGINEERING CORPORATION. Dec. 17, 1957, No. 39157/57. Class 106 (2). [Also in Group XXXVIII] In a pressure measuring device of the hypsometer type, two thermistors 15, Fig. 1, are located at one end of a fibreglass wick 13, the other end of which extends into a mass 12 of glass wool packing saturated with a liquid having a stable high boiling point, e.g. methylcyclopentane, and a heater element 14 around the wick is energized from a D.C. source 26 to boil the liquid, a control thermistor 20, disposed around a constricted portion 18 of the elongated container 10 which holds the saturated glass wool, being connected in the heater circuit to vary the heater output in accordance with changes in the temperature of the liquid. Liquid without glass wool packing may be used in suitable cases. The lower portion of container 10 is encased in a housing 21 and surrounded by a heat-insulating material; if the latter is selfsupportingly rigid, as is e.g. " Styrofoam " (Registered Trade Mark), the housing 20 may be dispensed with. The upper portion of container 10 provides a cool surface on which the vapour from the wick 13 may condense. A shunt resistor 24 for connection to the control thermistor is fixed to the housing 20 or the insulation 22; alternatively, several control thermistors, with or without shunts, may be used. Fig. 3 shows a D.C. bridge circuit into which either thermistor 15 may be connected by a switch 30, the bridge output being applied to a modulation circuit 32. Alternatively, the thermistors may be connected directly into a suitable modulation circuit.

Abstract: 987,398. Stoppers. WICANDERS (GREAT BRITAIN) Ltd. Feb. 2, 1962 [Nov. 16, 1960], No. 39402/60. Heading B8T. A replaceable bottle closure, e.g. of polythene, has a milled skirt 2 with a bead 3 for engaging around the bottle neck, and a plug portion 5 with a flat base 5 and a lower wall 7 of greater thickness than that of an upper wall 6. Sealing fins 8 for engaging the bottle neck interior are provided. An increase in pressure within the bottle causes the plug to decrease in length and provide an improved sealing. In a modification, instead of fins, a slot 9 provides plug flexibility.

Filed: 1970-08-17
Abstract: 1,261,667. Air intakes for jet engines. MESSERSCHMITT-BOLKOW-BLOHM G.m.b.H. Aug. 17, 1970 [Sept. 2, 1969], No.39621/70. Heading F1G. An air intake duct 1 for a jet propulsion engine is provided with a double-walled auxiliary intake door 4 which opens into the duct. The door comprises an inner door 5 which is pivotally mounted at 6 to the wall of the intake duct and which in its closed position conforms to the inner contour of the duct, and an outer door 8 which is pivotally mounted at 9 to the inner door and which in its closed position conforms to the outer contour of the wall of the intake duct. The inner door 5 is formed with perforations 11 and a tension spring 10 is connected between the two doors. In Fig. 1 the auxiliary intake is closed by the inner and outer doors, this being the position when the aircraft in which the engine is mounted is moving above a certain minimum speed, the pressure within the intake duct being communicated through the apertures 11 to the space between the doors and so acting to close the outer door. When the engine is stopped and the aircraft is stationary no differential pressure exists and the outer door abuts against the inner door due to the action of the tension spring 10 but the inner door remains in the closed position against the abutment 12 due to the action of the tension spring 7. When the engine is running and the aircraft is stationary the inner door 5 pivots inwardly due to the suction pressure in the intake duct and the outer door 8 remains in contact with the inner door due to action of the tension spring 10, and air-flows in through the auxiliary intake as shown.

Abstract: 1348347 Filters H H BURKHARDT H M KURTZ and M KURTZ [trading as HERMANN FINCKH METALLTUCH - UND MASCHINENFABRIK] 25 Aug 1971 [16 Aug 1970] 39876/71 Heading BID Apparatus for filtering a suspension of solid material in a liquid comprises a housing having an upper part 24' having a liquid inlet 28' and detachably mounted on a lower part 10 having a filtered liquid outlet 12. The housing has inner and outer filter screens 22, 44 mounted non-rotatably in parallel therein and a pair of rotor members carrying vanes 38' which are rotated by motor 14 adjacent the inner surfaces of the two filter elements. The housing upper part has a separated dirt collection channel 32' with outlet 34'. The outer filter basket 44 has larger apertures than inner filter basket 22 and has at its base even larger apertures 46 which effectively provide a by-pass for the outer filter basket. Suspension to be filtered enters at 28' and then divides-part being filtered by outer element 44 and then flowing up over the rotor cross arm 36' and down to outlet 12 whilst the remainder by-passes the outer element and passes through apertures 46, around baffles 48 and is filtered by inner element 22. In another embodiment (Fig. 2 not shown), the two filter baskets 22, 44 are arranged in series, the by-pass apertures 46 being absent and the top of inner basket 22 being closed by a plate (60). The interior of the filter housing is vented by ventilation valve 40'. In the Fig. 2 embodiment the interior of the inner filter element is separately vented by a valve (64).
