Abstract: 1,234,814. High-speed photography. RHEINMETALL G. m. b. H. June 28, 1968 [July 28, 1967], No.31158/68. Headings G2A, G2E and G2J. In a method of photographing rapidly moving bodies, the moving body is imaged on to a filmstrip 2, moving in the opposite direction to the body, by means of multiple pivotally mounted lenses 11-15 whose optical axes 71-75 intersect the trajectory of the body at intervals which determine the picture frequency. The lenses are carried in control heads 22 at different levels to give a staggered image array across the film width, and their convergence is controlled by a worm-gear connection between each head 22 and a common manually rotatable shaft. Each worm and gear has a pitch chosen to provide a symmetrical convergence of axes 71-75. Interchangeable image slits 40 removably fit dovetails 42 in heads 22. Film 2 passes from reel 32, through apertures 38 and over guide surfaces 24 in heads 22, to take-up reel 28 rotating in a damping cylinder 30.

IPC: B07C3/06
Filed: 1949-12-06
Abstract: 700,674. Escapement mechanism. POSTMASTER GENERAL. April 2; 1951 [Dec. 6, 1949], No. 31314/49. Class 80 (4) Stepped rotation of the driven member 11 of a uni-directional coupling from a continuous driving member 4, particularly for operating oscillating vanes 33 of a postal sorting machine of the type described in Specification 675,556, [Group XL (b) ], through gears 23, 26 and a crank 29, is obtained by controlling the drive through the coupling by a double star-wheel member 17, 18 carrying disengaging projections 16 for the rollers 15 of the coupling and cooperating with the armature 20 of an electromagnet. The star-wheel 17, 18 is rotatably mounted on a hub 12 of the driven member 11 of the coupling and when held by the engagement of a tooth of its upper or lower wheel with the armature 20 disengages the rollers 15 so that no drive is transmitted from the member 4. If the armature 20 is then moved out of engagement with one star wheel into the path of the teeth of the other star wheel the projections 16 release the rollers 15 under the action of their springs 19 so that the coupling is effective to drive the member 11 and star-wheel 17, 18 until the next tooth of the operative star wheel engages the armature 20 to disengage again the rollers 15 and bring the member 11 to rest. Thus successive steps of one-eighth of a revolution of the driven member is obtained, if an eightpointed star-wheel 17, 18 is used, on successive operations of energizing and de-energizing the electromagnet. A pawl 25 co-operating with a toothed wheel 24 secured to the gear 23 is provided to prevent back-running.

Abstract: 377,532. Controlling aircraft engines. TAMPIER, R., 1, Rue de Bellevue, Boulognesur-Seine, France. Nov. 12, 1931, No. 31360. Convention date, Nov. 12, 1930. [Class 4.] A hand-lever for controlling t h e throttle of the carburetter works in conjunction with a series of cams or stops 7, 8, 9 corresponding to predetermined throttle openings, a catch 18 on the lever being raised to different positions by a handle portion 20, so as to evade some or all of the stops. When the catch is raised sufficiently to pass over all the stops 7, 8, 9, the lever then contacts with limiting stops 13, 14 comprising adjustable cams or eccentrics. The stops 7, 8, 9 are carried by arms adjustable about the axis 2 of the lever, and are fixed by nuts 24 on pins 23 moving in a slot 25 in a fixed sector 6. The handle 20 is formed with slots 22, Fig. 4, engaging a pin 21 and of lengths corresponding to the heights of the cams 7 8, 9, so that by rotating the handle until the pin 21 comes into one or other of the slots, the desired amount of lifting of the catch 18 is ensured.

Title: A method of and apparatus for continuously coating one side of a metal band in a fluidised powder bath
IPC: C23C24/00
Filed: 1964-08-04
Abstract: <PICT:1013334/C6-C7/1> A metal strip is continuously coated on one side with a sinter coating by conducting the strip via guide rails over a fluidized powder tank so that the strip seals the open top of the tank between the two guide rails and the level of the fluidized bed is elevated into open top shafts of the tank above the level of the strip only during the actual coating process.  As shown, in Fig. 1 the tank 2 has two open shafts 5, guide rails 8 and 9 through which the metal strip 10 is continuously drawn, and compressed air is admitted via pipe 3 through perforated floor 4.  The strip 10 is passed through an induction heater and then through the tank 2, and the powder level in the tank is raised by inflating the bladders 13 so that the heated strip 10 is coated with the powder. Alternatively the powder level may be raised by lowering solid bodies into the powder or by expanding the perforated floor of the tank which may be a filter cloth.

Title: A cinematograph film for producing colours subjectively
IPC: H04N11/00
Filed: 1954-11-10
Abstract: 755,194. Subjective colours in kinematography. NAGLER, sen. J., and NAGLER, jun. J. Nov. 10, 1954 [Nov. 11, 1953], No. 32591/54. Classes 97 (1) and 98 (2). A kinematograph film is provided with contrasts of light and dark, as between successive frames, whereby a subjective colour impression is produced by the Fechner-Benham effect. Thus, Fig. 7 shows a film in which three adjacent frames of each sequence of seven are blackened, the first of the remaining four being shaded. This gives a red impression. If the last of the four frames is shaded the impression is blue and if the central pair are shaded the impression is green. If the shading is by parallel lines as shown, the lines of the " red," " blue " and " green " frames are relatively staggered. Also the lines of successive frames corresponding to any one colour may be staggered. The shading shown produces a colouration of the whole frame. To produce a coloured image of an object the shading is limited to the image of the part of the object required to be of the colour which the particular shading produces. A film of a natural scene may be produced by exposing the four frames in each sequence of seven through red, green (two) and blue filters in sequence.
