Title: Photographic apparatus for use with flash lamp assemblies
IPC: G03B15/04
Filed: 1971-06-29
Abstract: 1346255 Photographic flash apparatus POLAROID CORP 29 June 1971 [29 June 1970] 30436/71 Heading G2A Photographic apparatus for supporting a percussive flash-cube 10 comprises a dual carriage assembly, the outer carriage 32 of which is formed with gripping members 64 which releaseably engage indentations 24 of an inserted flashcube, and the inner carriage 74 of which has a post 76 over which the stem 18 of an inserted flash-cube 10 fits, thereby coupling the two carriages together for anti-clockwise Fig.3 rotation. On removal of an inserted unit, the inner carriage 74 is rotated clockwise by a spring (90) Fig. 2, (not shown), until a tab 84 assumes a position 84' abutting a stop 96. Sequence of operation The apparatus can be operated by a reciprocatory motion derived from the operation of a photographic shutter. Depression of the shutter release button causes a camming flange (106) Figs. 4-6 (not shown), to take up a position engaging the tip 60 of a tab 50 of the outer carriage 32. The appropriate bulb is fired and the flange (106) moved to the right, thereby rotating the carriages and flash unit anticlockwise to an over-ride position (Fig.4). When the shutter button is allowed to rise, the override is terminated, allowing the flange (106) to return latching element 40 to engage a stop member (112), thereby correctly positioning the flashcube for the next exposure. As the carriages 32, 74 rotate during a succession of exposure cycles, the tab 84 rotates from its dotted line position 84' to its solid line position. When the latter position is reached, further rotation of the carriages and flash-cube is prevented, and a further exposure is also prevented. The flashcube may be finally arrested at a position about 45 degrees out of proper alignment.

Title: Photographic recording of television pictures
Inventor: GRIFFITHS LESLIE HAROLD
IPC: H04N5/84
Filed: 1958-09-26
Abstract: 859,030. Television. BRITISH BROADCASTING CORPORATION. Oct. 22, 1959 [Sept. 26, 1958], No. 30877/58. Class 40(3). Relates to apparatus for recording television pictures produced on a cathode-ray tube screen 11, Fig. 1, with the aid of an intermittent motion film camera 10 which has a pull-down time greater than the television field blanking interval, the camera shutter being timed so as to open at a time subsequent to the start of each field, as illustrated in Fig. 2 at (a) and (b), and the tube screen having a persistence such as to permit recording of that part of field which is scanned before the shutter opens. According to the invention, the variation in picture intensity in the frame scan direction due to fading, which at the instant of opening the shutter takes the form shown in Fig. 2(c), together with the variation due to differing exposure times of those parts of the image scanned after opening the shutter, are compensated by the provision of an optical filter 18 graded in density in the frame scan direction in the manner shown in Fig. 2 (d). The filter may be placed against the tube screen, as illustrated, with the interposition of an optical cement or liquid 19 having a refractive index intermediate those of the glass face of the tube and the filter material. Alternatively the filter may be located inside the camera close to the image on the film. The camera pull-down operation is correctly timed with the television fields by means of a drive unit 15 which is fed with field synchronizing pulses and pull-down indication pulses. For recording interlaced television pictures the pull-down is arranged to occur during every alternate operation of the shutter, i.e. once for every two television fields.

Title: Improvements in cameras provided with photo-electric exposure meters
IPC: G03B7/06
Filed: 1939-11-30
Abstract: 539,450. Photographic exposure meters. THIEMANN, W. H. A. (Henriksen, P. E.). Nov. 30, 1939, No. 31167. [Classes 97 (i) and 98 (i)] In a camera having an exposure meter formed by a photo-electric cell and a moving- coil meter the pointer of which is aligned with a mark for obtaining the correct exposure, the meter is angularly adjustable about the axis of rotation of its coil in accordance with preselected exposure factors, thus varying the current flow necessary to align the pointer with the mark in accordance with these factors, and the current flow is adjusted by electrical or optical means coupled to a member which simultaneously adjusts a further exposure factor to a value appropriate to the brightness of the scene and the pre-selected exposure factors. In the kinematograph camera shown in Figs. 1, 2, and 3 the meter casing 7 is rotatable by means of a knob 9 to bring an index 12 upon it opposite one of a series of graduations 13 on the side of the camera, and the pointer 6 co-operates with an index mark 10 on the viewfinder lens 3. A rotatable disc 19 is turned to adjust the mechanism to expose the desired number of frames per second, as indicated by a scale on it co-operating with a fixed index 25, and a disc 15 is set so that the correct emulsion speed on a scale carried by it is indicated by an index 21 on the disc 19. An index 17 on the disc 15 then indicates the graduation on the scale 13 to which the index 12 on the meter casing is to be adjusted. The pointer 6 is then brought to the index mark 10 by adjustment of an iris diaphragm 28 which controls the amount of light passing to the photo electric cell 26, a corresponding adjustment of the lens diaphragm being effected through gear segments 31, 32. In a modification, the meter is arranged with its axis horizontal and coincident with that of the setting discs 15, 19, which are on the front of the camera. In the form shown in Fig. 12, a disc 48 is adjusted to set the frame speed, as indicated by a scale on it, and carries a further scale 52 indicating emulsion speeds and co-operating with fixed graduations 13". A knob 45, which rotates the meter casing, is then adjusted so that an index 47 on it is opposite the graduation 13<SP>11</SP> corresponding to the emulsion speed. The cell and lens diaphragms 28, 34 are then adjusted simultaneously, as in the form first described, until the meter pointer 6 is opposite a fixed index mark 10. The arm 57 by which the diaphragms are adjusted may also serve, when moved inwardly, to start the spring motor; alternatively, the angular movement of the arm may control the motor and the in-and-out movement of the diaphragms. When an electric motor is employed the controlling switch may be carried by the arm.

Abstract: 520,710. Conveyers for bottles. DOBRENTEY, A., and BRITISH MILLER HYDRO CO., Ltd. Oct. 29, 1938, No. 31297. [Class 78 (i)] In bottle-washing machinery the bottles delivered in an upright position along the conveyer 11 are transferred laterally to the pockets 10 of another conveyer in which they are supported in inverted position, and the transfer device moves in unison with the last conveyer during the transferring process. Initially, the bottles are spaced along the conveyer 11 by the star wheel 31 shown in plan in Fig. 4. This wheel is rotated intermittently by friction with the belt 11 and by pressure of the bottles, whenever the toothed wheel 34, Fig. 2, on the lower end of its shaft 32 registers with a space 35 on the notched wheel 33 rotated continuously by the camshaft 21. The spaced bottles are moved laterally into pivoted carriers 12, Fig. 3, by pushers 25 actuated by linkage 26, 29 from the cam 27. The carriers 12 are then rotated about the pivot 13 through 90 degrees to lay the bottles flat by the linkage 16, 17 operated from the cam 20. This movement allows the skeleton bottle-holders on the carrier to pass bottleholding tables 42, Fig. 5, carried by arms pivoted at 48. When these arms are raised by linkage 50, 51 operated from the cam 49, the bottles are picked up from the carriers, upended over the'pockets of the conveyer 10 and gradually lowered into the latter. At the same time a roller arm 56 depending from the arms moves relatively to a cam 55 to swing the arms about the axis 54 so that they travel with the conveyer 10 during the transfer. The cam 55 is reciprocated from the cam shaft 21. Forks 45 operated by cams 70 engage the bottle necks during this last transfer and are gradually lowered to release them as they enter the cups.
