Patent GB-123786-A (GB)
Title: Improvements relating to Polychrome Cinematography.
Inventor: HAMBURGER ARON
IPC: G03C7/22
Filed: 1917-12-03
Abstract: 123,786. Hamburger, A. Dec. 3, 1917. Colour photography; toning and after-treatment; trays, dishes, and containers for lengths of film.-Kinematograph films in colour are produced by dyeing or otherwise colouring practically simultaneously both sides of a doubly sensitized film which has been printed and developed. The dyeing may be effected by means of endless absorbent bands, the bands passing. with the film between them, between rollers which press them on to the film, and afterwards between perforated rollers through which dry steam is emitted on to the bands to fix the dye. Means are provided for saturating the bands with dye before they reach the pressure rollers, and the rollers are preferably mounted on vertical axes. Dyeing may alternatively be effected by means of frames g, Fig. 4, which form closed tanks in conjunction with the film, as described in Specification 128,787, the frames being mounted to form endless chains which pass round spring-pressed polygonal rollers l. The frames g carry frames h, Fig. 7, securing rubber strips i which seal against the film, and also carry glass plates j, which are perforated to permit the passage of dye through inlet and outlet passages k. The frames are connected to form chains by links m, and are provided with holes which engage projections p on the roller l. The frames may be closed on to the film 'by means of a spring, and may be separated by a simple linkage when, after a section of the film has been dyed, it is desired to move on the chains to dye the next section of the film. Spigots n on each frame engage holes in the opposing frame to position the frames relatively to one another. Dye is fed to the frames from tanks which are connected to them, the tanks being raised for this purpose and being afterwards lowered to alow the dye to run back into them; alternatively, the dye may be circulated through jets on to the film. The invention may also be carried into effect by bleaching the images on the film and colouring them in one operation. Carbnn paper or dye gelatine paper is soaked for a time. say five minutes, in a solution of copper sulphate, 4 oz.; potassium bromide, 1400 grains; potassium bichromate, 180 grains; and hydrochloric acid, 80 minims, in 40 oz. of water, and is passed between pressure rollers in contact with the film. The silver images while in contact with the treated carbon or dye gelatine papers are bleached, coloured, and hardened, and the soft gelatine is afterwards dissolved in hot or cold water, the papers floating away and leaving the coloured images free on the film.

Title: Improvements in and relating to electric motor control systems
IPC: H02P3/08
Filed: 1935-06-28
Abstract: 450,790. Control of D.C. motors. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London. June 28, 1935, No. 18589. Convention date, June 30, 1934. [Class 38 (iii)] A control system for a motor 10 in which braking is effected by plugging the motor, comprises forward and reverse contactors 13, 14, plugging resistance 17 and accelerating resistances 18, 19 connected between the plugging resistance and the motor, relays 24, 25 for controlling the short-circuiting of the plugging resistance, circuit connections controlled by the contactors 13, 14 for selectively energizing the relays in dependence upon the direction of energization of the motor, and a rectifier 27 which prevents energization of the relays in response to the voltage drop across the motor and accelerating resistances when the motor is plugged, but allows operation of one of the relays after reversal of the polarity of the voltage drop as the counter voltage of the motor decreases. To start the motor in the forward direction, a master switch 23 is moved to its first forward position, whereupon the contactor 13 closes and connects the motor to the lines 11, 12 through the whole of the resistances. At the same time, the relay 24 is energized through auxiliary contacts on the contactor 13, and prepares an energizing circuit for the plugging contactor 20, which circuit is completed when the switch 23 is moved to its second position. The contactor 20 then closes and short-circuits the plugging resistance 17. The accelerating contactors 21, 22 are controlled by relays 38, 39, the coils of which are respectively connected across the resistances 17, 18. These relays are preferably of the type described in Specification 175,815, [Class 38 (iii)], and have a delay action, so that the relay 38 does not close its contacts until a time interval has elapsed after the closing of the contactor 20. If the switch 23 is now in its third position, the response of the relay 38 energizes the contactor 21 which cuts out the resistance 18, and after a further interval the relay 39 energizes the contactor 22 which cuts out the resistance 19. If it is desired to plug the motor to rest, the switch 23 is thrown to the full reverse position, thereby de-energizing the contactors 13, 20, 21 and 22, and the relay 24, reinserting the resistances 17 ... 19, and energizing the contactor 14 to connect the motor to the line in the reverse direction. The relay 25 is prevented by the rectifier 27 from operating to energize the plugging contactor 20 until the speed and counter voltage of the motor have fallen sufficiently to cause the potential of the junction point 26a to become negative with respect to the potential of the point 26 on the line side of the motor. When this takes place, the relay 25 is energized and the contactor 20 shortcircuits the plugging resistance.
