Title: Improvements in photographic cameras with photo-electric exposure meters
IPC: G03B7/04
Filed: 1937-07-01
Abstract: 500,188. Controlling exposures in photographic cameras. TONNIES, H. July 1, 1937, No. 18301. Convention date, July 1, 1936. [Class 98 (i)] A photographic camera is provided with a photo-electric exposure meter consisting of a light-sensitive cell, a galvanometer, and an electrical or optical device for controlling the cell current coupled to a displaceable part of the shutter or diaphragm, the galvanometer including relativety adjustable members carrying scales of photographic factors and a mark with which the galvanometer needle registers when the shutter or diaphragm is correctly set. The device may consist of a uniform or non- uniform resistance in the circuit of the cell or of a diaphragm or screen arranged in front of the cell. In the form shown in Fig. 1, the diaphragm of the camera lens 2 is adjusted by a slider 4 moving over a resistance 5 in the circuit of a cell 6 and galvanometer 8. The latter carries a scale 24 over which the galvanometer needle moves and a ring 16 graduated in degrees Scheiner which is adjustable over a fixed scale of exposure times and carries a mark 12 moving over the scale 24. An additional ring 18 carrying scales of exposure times and film speed values and additional scales on the ring 16 may be provided as shown in Fig. 2 for use when the resistance 5 is put out of the circuit by moving the slider 4 to the extreme end. In a modification, a plate carried by the shutter adjusting ring or geared thereto is moved in front of the light-sensitive cell, the resistance being omitted. In place of a uniform resistance a tapered resistance may be used. The light-sensitive cell may also be of tapered shape. Alternatively, two cells with grids for screening indirect light may be arranged on opposite sides of the objective of the camera as shown in Fig. 8.

Abstract: 497,970. Type-printing telegraphy. CREED & CO., Ltd., and SALMON, R. D. July 2, 1937, No. 18435. [Class 40 (iii)] [Also in Groups VIII and XVI] Keyboard combinationselecting mechanism for telegraph transmitters, statistical card or tape perforators, &c. comprises identical setting bars associated with the keys, a set of identical selector members controlling impulse transmission or card &c. perforation and intermediate selecting elements, all of similar formation, which determine the code by their preset disposition relative to the setting and selector bars. Individually constructed parts for the different combinations are thereby avoided. As shown, each key lever A-I operates longitudinally movable bars A<1>-I<1> formed with identical sets of projections 13 engaging the arms 16 of bell-crank selecting elements 14 which are pivoted on supports 3-7 and have their other arms 17 engaged in slots in identical selector bars 8-12 longitudinally movable in the supports 3-7. In the case, as shown, where it is required that a key bar should move a combination of selector bars up or down in Fig. 1, bell-cranks are disposed at the intersections of the key-bar with the required bars 8-12 to the right or left of them, the bell-cranks being identical except for the pivoted portions which embrace the supports 3-7. When it is required that the selected bars S-12 should move in one direction only, the bell-cranks are all on one side of the bars and are strictly identical. The bell-cranks are readily detachable.

Abstract: 726,795. Valves. MAGNESIUM ELEKTRON, Ltd. July 21, 1953 [July 23, 1952], No. 18616/52. Class 135. In a valve more especially for vacuum apparatus the actuating stem 18 is sealed where it passes through a bearing 14 in a cover-plate 11 by a round-section packing ring mounted in a chamfer or groove 16 and pressed by a plate 19 into engagement with the stem. A sealing ring 36 within a groove in the stem passes into the bearing 14 to form a seal when the valve is fully open, so that the packing ring 17 may be removed and replaced without loss of vacuum. The closure member 30, which is secured to a head 43 of the stem by a plate 44, is held open by engagement of a pin 35 on the stem with a fixed hook 37. Closure of the valve, after the stem has been pushed inwardly to engage a threaded part 25 at the upper end thereof with a threaded boss 21 on the plate 19, is effected by rotation of a hand-wheel 24. The valve may, alternatively, be of the kind described in Specification 726,796.

Title: Improvements in or relating to x-ray apparatus
IPC: H05G1/40
Filed: 1929-06-17
Abstract: 334,639. Cox, S. June 17, 1929. R÷ntgen-ray apparatus.-Means for controlling time exposures in X-ray photography include a pointer and a dial having markings to indicate different parts of the human body. The dial and pointer are rotated relatively to each other until the pointer coincides with a desired marking on the dial, the time of exposure then being such as is required by the part of the body indicated at the selected markings. In one form, the dial 1 has, for each part of the body, three markings distinguished by different colours, lengths or thicknesses and positioned according to the exposures necessary for a child, normal person and heavy person. The circuit for the X-ray tube is completed through the contacts 9 and 11 and the switch 15 which is normally open. The dial 1 is mounted on the spindle 6 of a gear wheel carrying a projection 7 which in the rest position opens the switch 9, 11. In operation, the dial is rotated clockwise until a selected marking is opposite the fixed pointer 12, the spring 5 being tensioned and the dial being retained in the set position by a pawl 19 carried by a freely-mounted wheel 20 which is prevented from rotation by the catch 17. To start the exposure, the press button 13 is moved to close the switch 15. The catch 17 is simultaneously withdrawn, and the dial 1 rotates anticlockwise until the projection 7 breaks the circuit at the contacts 9, 11. Alternatively the dial may be fixed, and the pointer mounted on the spindle 6. The contacts 9, 11 may be dispensed with, and the projection 7 adapted to release the press button 13 to break the circuit.

Abstract: 498,142. Cables. CALLENDER'S CABLE & CONSTRUCTION CO., Ltd., HILL, H., and ROSE, T. B. July 8, 1937, No. 19008. [Class 36] A conductor of non-circular shape for an electric cable comprises a number of component conductors which are formed by stranding wires together and have shapes such that when they are assembled together they enclose a duct extending longitudinally of the conductor and fit into each other in a self-supporting manner so that no internal supporting hollow core member is required. In the Figure, the conductor has a duct 5 and is built into an elliptical shape by means of components A B C and D. The components are made by stranding together wires (which may be of different diameters) and they are held together by the layer 2 of wires applied helically, or by a single wire. The component conductors may lie parallel with the axis of the conductor or they may be stranded together, and they may be prespiralled before being stranded together with a lay equal to the stranding lay, Three such conductors with their insulation may be combined in one sheath and the component conductors may be prespiralled with a lay equal to that of the cabling lay. Specification 474,695, [Group XXII], is referred to.
