Title: Improvements in or relating to photographic cameras
Inventor: BARHAM PETER MILTON
IPC: G03B7/085
Filed: 1960-08-18
Abstract: 922,016. Photo-electric exposure control. MINISTER OF AVIATION. Nov. 16, 1961 [Aug. 18, 1960], No. 28645/60. Class 40 (3). [Also in Groups XX and XL (c)] Automatic aperture control means comprise a plurality of devices responsive to light from respective parts of a field of view and arranged to increase and/or decrease the aperture when any of them receives too little or too much light respectively. Four photo resistors E1- E4, Fig. 1, are arranged around the " format " F in the focal plane of the camera lens, and are in series with actuating windings of respective relays R1-R4. When photo resistors E1- E4 receive illumination satisfactory for exposure, the relays are as shown with no contacts made. The upper contacts of relays R1-R4 are in parallel so that if any one of photo resistors E1-E4 receives less than a predetermined level of illumination the corresponding upper contact closes to energize a winding O of a motor M to open the aperture. Since the lower contacts are in series, every one of photo resistors E1-E4 must receive more than a predetermined illumination before winding C is energized to close the aperture. The predetermined levels are adjusted by switch S which controls the current in bias windings of relays R1-R4. In modifications, slave relays may be employed, and connections may be such that one photo resistor may initiate closure of the aperture but all are necessary to open it. In a second embodiment, Fig. 3 (not shown), the photo resistors are connected in series with ohmic resistors, the junctions being connected through diodes to the base of a transistor which, acting as an emitter follower, controls the motor.

Abstract: 461,805. Making metal flooring &c. by welding. ROBERTSON CO., H. H., YOUNG, J. H., and BLACK, G. E. Oct. 22, 1936, No. 28747. [Classes 83 (ii) and 83 (iv)] In making cellular metal building units, such as flooring units, the component members, one at least of which has flat longitudinal corrugations, are assembled and the web portions intermediate the cells are welded along paths so close to the side walls that closed cells are formed. The member 22 may be corrugated as shown in Fig. 3, and the member 20 may be corrugated as shown, or may be flat with edges projecting in the manner shown. The members are assembled and passed between a number of pairs of feed and positioning rolls 24, 26, adjustable by screws 62 through springs 58, geared together at 68, 70 and driven by bevel gear 52, 50 from a shaft 48 rotated either continuously or intermittently by a motor 32 through adjustable belt gear 34 and worm gear 35. The continuous, drive is effected by belt gear 40 and hand-operated clutch 46 from the shaft 36, and the intermittent drive is effected from the shaft 36 by belt 78, adjustable crank 80, link 84 and ratchet gear 82. Four sets of electric welding rolls may be used spaced longitudinally and laterally from each other so that welding is effected successively at different joints adjacent the side walls and edges of the assembly in order to prevent overheating. Each welding unit may comprise two pairs of water-cooled discs 12, 13 carried in yokes 14, 15 on rods 16, 17 and floatingly mounted by levers 102, rods 104 and hydraulic cylinders 105, so that the sheets are not forced from normal position by the welding pressure due to flattening of the discs. Springs 106 are provided between the cylinders and collars 108 on the rods 104. The upper electrodes of each unit are connected to the opposite terminals of a separate transformer, the return circuit being via the lower pair. One of the levers 102 of each unit carries a switch member 150 so that current is cut off when the work has passed through the electrodes. For welding with an intermittent feed the shaft 48 may carry a cam engaging a bell-crank lever carrying the movable element of a further switch. The electrodes may be mounted on spindles offset from the rods 16, 17.
