Abstract: 1186143 Flash apparatus; flash-bulbs TOKYO SHIBAURA ELECTRIC CO Ltd 30 Jan 1968 [31 Jan 1967] 4693/68 Headings G2A and G2L A Piezo-electric element 4 is arranged to be impacted simultaneously with the shutter release, the resulting potential difference being utilized to fire a flash-bulb. The mechanism is supported in a frame 3 attached to the camera by means of a bracket 10. A push member 11 is secured to a plate 14 biased downwardly by springs 15. Member 11 is linked to an impact member 8 by means of a pin-and-slot connection 19, 20. The member 8 is supported from the frame 3 by a pair of toggle springs 22 which are more powerful than springs 15. Members 11 and 14 are pulled upwards against springs 15 until a spring-loaded catch 18 latches behind the bent-over end of member 11, and holds it there. Movement of member 11 also entrains upward movement of impact member 8, which is then sprung into its raised position (as shown) by the toggle springs. On pressing the cable release 26, catch 18 is pushed so as to release member 11. This is pulled downward by the springs, to strike the shutter release button 12. At the same time the impacter 8 is entrained again, and when it passes its dead centre position it is snapped strongly down by the toggle springs to impact the end 7 of the Piezo-electric element 4. A flash-bulb, Fig. 5 (not shown) containing shredded zirconium or aluminium foil, with an oxygen filling, has a discharge gap 103 formed between the bent-over ends of the lead-in wires 104 supported within the bulb envelope by a glass bead 105. The bent-over ends are covered by a coating of an ignition agent or primer bead 106. The glass bulb itself may have an explosionproof coating.

Title: Improvements in or relating to photographic exposure meters
IPC: G01J1/42
Filed: 1962-02-08
Abstract: 938,927. Photographic exposure meters. EASTMAN KODAK CO. Feb. 8, 1962 [Feb. 13, 1961], No. 4863/62. Class 40 (3). [Also in Group XX] The invention relates to an exposure meter which indicates the level of illumination of a surface to be photographed in a document photographing apparatus, and comprises a photo-conductive cell for measuring light reflected by the surface, means for irradiating the cell with a substantially constant flux of radiant energy to maintain the cell in a stable condition and means rendering the irradiating means ineffective when the cell is measuring the light reflected by the surface. In the embodiment shown the photoconductive cell 39 is connected in a bridge circuit with a further cell 43 used as a reference, a galvanometer 65 being used to indicate balance of the circuit. The cells are mounted in separate compartments of a metal block of a housing (Figs. 3 and 4, not shown) in order that they may be maintained at substantially the same temperature during measurement, the cell 39 having a neon lamp 41 mounted adjacent to it in its compartment and cell 43 having a neon lamp 45 similarly mounted. A switch 89 is connected across the lamp 41 and is operated in conjunction with a switch (not shown) which operates lamps 21 (Fig. 1, not shown) which illuminate the surface to be photographed, so that when the lamps 21 are illuminated, the lamp 41 is extinguished. The light from the lamps is reflected by the surface and sensed by the cell 39 as indicated by the arrows 91. The circuit components are selected and adjusted so as to balance the bridge when the surface to be photographed is correctly illuminated by the lamps to a level at which correct exposure will be made. In operation a surface to be photographed is placed in position and the illuminating lamps are turned on. This simultaneously extinguishes the lamp 41 and the level of illumination on the surface is sensed by the cell 39 the lamp 45 remaining illuminated throughout the operation. The brilliancy of the lamps is then adjusted for instance by a rheostat, until the galvanometer indicates balance of the bridge circuit at which time the surface is correctly illuminated for the photograph to be taken. A colour correction filter (Fig. 4, not shown) is placed over the end of the compartment in the housing containing the cell 39 to match the spectral response of the cell 39 to the light reflected from the surface to be photographed.

Title: Improvements in or relating to Stand-by Lubrication Systems
IPC: F16N29/02
Filed: 1968-01-31
Abstract: 1,167,692. Lubricating. LINDE A.G. 31 Jan., 1968 [3 Feb., 1967], No. 4865/68. Heading F2A. A stand-by lubrication system for a pressure-lubricated machine has a lubricant-containing reservoir 18 having an outlet connected through a level-responsive cut-off valve 23 to a main feed-line 3, via an oil-feed line 22; and has control means 8 responsive to a fall in pressure in the main feed-line 3 to connect the upper part of the reservoir 18 to a pressurized-air supply. In use lubricant is pumped by a pump 2 to a main feed-line 3, via a check-valve 3a, is fed to lubrication points 4, and is returned through a back-pressure valve 5 and a line 6 to a main reservoir 1. Pressurized fluid is also pumped by the pump 2 through a pipe 7 so as to force a valve spool 9 of the control means 8 against a spring 10. If the pump 2 should fail, the pressure in the line 7 falls and the spool 9 is urged by the spring 10 so that the top of the reservoir 18 is connected to a pressurized-fluid supply 11, via a connection 12, a change-over valve 13 and a line 17. The lubricant is forced through the cut-off valve 23 and the line 22 into the main feed-line 3, the valve 23 closing before the full amount of lubricant has been discharged from the reservoir 18. When the pump 2 recommences pumping, the pressure in the line 7 rises, the spool 9 is forced against the spring 10, the connection 12 communicates with an air-bleed line 13a and the pressurized-fluid line 11 is shut off. Lubricant is simultaneously forced into the reservoir 18, via the line 22 and the valve 23; and air is forced out of the top of the reservoir 18 to atmosphere, via the line 17, the valve 13, the connection 12, the control means 8 and the line 13a. When the reservoir 18 is full of lubricant and a diaphragm 14 in the valve 13 is raised by the lubricant, an air-bleed outlet 15 of the valve 13 is closed and a quantity of lubricant is passed through a throttle 20, an inspection glass 21 and a line 19 to the main reservoir 1.
