Abstract: 758,573. Colour photography. HICKETHIER, E. A. May 28, 1954 [June 19, 1953], No. 15865/54. Drawings to Specification. Class 98 (2). Colour separation records stated to be colourcorrected are made from a multilayer image having yellow, magenta and cyan part images by printing each pair of the three part images in turn on to an appropriately sensitized multilayer material, converting the latter into a twocolour print which is equal but negative to the pair printed, and printing through the original multilayer image in register with each of the two-colour prints. In a modification appropriately sensitized single layer materials may be used for production of the two-colour print, such single 'layer materials being combined with each other after conversion into single colour prints. The printing pair sequences using lights and two emulsion layer materials of corresponding sensitivity may be (1) blue and green with yellow filter between the two layers, (2) blue and red with yellow filter placed similarly, and (3) green and red with yellow filter overlying both layers; or printing sequences may be effected on to a sensitive material similar to that used for making the original multicolour image, with use of yellow, magenta and cyan filters. Processing may be by colour development with colour formers in the layers or in solutions. The final printings through the registered multilayer image and two colour image pairs (1), (2) and (3) may be by red, green, blue or white light on to materials of appropriate sensitivity and a screen may be interposed to result in half-tone separation records.

Title: Means for automatically obtaining variation of the output of a dynamo operating in conjunction with a storage battery
IPC: H02J7/32
Filed: 1925-06-19
Abstract: 237,881. Bossu, P. July 30, 1924, [Convention date]. Systems of charging galvanic batteries.-A resistance in the field circuit of a dynamo charging a storage battery is automatically inserted by a relay and the dynamo voltage is thereafter prevented from reaching its maximum when the normal charging current is exceeded. The relay is polarized either by a winding in the dynamo field circuit or by a permanent magnet armature controlling the effect of the action of the relay armature proper. The invention is applicable to any dynamo but is described as applied to a variable speed dynamo having auxiliary brake regulation and to a reaction dynamo of the Rosenberg type. The former is shown in Fig. 1, the polarizing shunt winding e<1> and the series windings e<2>, which is connected so as to carry the battery current only, assist each other when the battery is charging and above a certain rate of charge the resistance g, which may be adjustable, is inserted into the field circuit. The winding e<2> is designed to be unable to open the switch h when the dynamo is not running. According to Fig. 2, the switch h is actuated by a series coil c<2> only and a permanent magnet m (which may be spring controlled) forms part of an auxiliary switch h<1> and prevents the insertion of the resistance g by the switch h when the battery is discharging. The arrangements described permit the increase of dynamo output directly the external circuit d is brought into use bv instantaneously increasing the dynamo excitation to a maximum. Since the relay is controlled by the battery charging current a sulphated battery is desulphated, since it must always take its normal charging current before the relay operated to limit the charging voltage. In the Specification as open to inspection under Sect. 91 (3) (a) the resistance was stated to be introduced into the field circuit periodically or otherwise. This statement does not appear in the Specification as accepted.

Filed: 1936-06-09
Abstract: 476,573. Forging - press. EVANS, W. E. (Hydraulik Ges.) June 9, 1936, No. 16131. [Class 83 (iv)] [Also in Group XXIX] In an hydraulically-operated forging- press of the pump piston type with fluid control, electrically actuated drive to pump and variable pressure between pump and working cylinder, the return stroke cylinders are under the constant pressure of an accumulator connected with the pressure pipe between the working plunger and pump plunger through hand-operated valves. As shown, the working cylinder 1 is connected by a pipe 9 with the pump cylinder 10 having a plunger 12 driven from a shaft 11, which also operates a plunger 15 of a cylinder 16 connected by a pipe 17 to a valve casing 22. A valve casing 31 with a non-return valve 32 has handoperated valves 33, 34, 35 and is connected at 30 to the pipe 9, which is connected by a pipe 37 to an accumulator and by a pipe 38 to a tank 24. An accumulator 20 is connected by a pipe 41 to the return stroke cylinders 5, the pipe 41 being also connected to the pipe 37. A spring pressed plunger 27 works in a cylinder 26 connected by a pipe 25 to the accumulator and is attached to a valve 21. A non-return valve 19 controls connection to the accumulator. With the valve 33 closed, the piston 2 remains uniform in stroke. With the valves 33, 34 open and the valve 35 closed, water flows into the pipe 9 for lowering the press tool on to the work. Thereupon, when the driving shaft operates by starting a motor or throwing in a clutch in the driving mechanism, the piston 2 makes a working stroke regulated by the position of the throttle valve 33 in conjunction with the valves 34, 35.

Title: Improvements in or relating to apparatus for determining variations in width of travelling transparent birefringent film
Inventor: LINSLEY-HOOD JOHN LAURENCE
IPC: G01B11/04
Filed: 1962-04-27
Abstract: 956,636. Electric selective signalling. BRITISH CELLOPHANE Ltd. March 28,1963 [April 27, 1962], No. 16253/62. Heading G4H. Apparatus for determining variations in the width of a travelling birefringent film 2, Fig. 1, comprises two edge detecting heads 1 and 1<SP>1</SP>, one for each edge of the film, and a signal integration 8 for summing signals received from both heads, each detecting head, Fig. 2, including a light source 9, a first polarising means 11, for plane polarising light emitted from the light source, a second polarising means 19 so orientated that it extinguishes light passing directly from the first polarising means, at least two photo-electric cells 13 capable of being activated by light passing through the second polarising means, and spaced apart in a direction transverse to the direction of travel of the film 2, the first and second polarising means being separated to provide a passage way through which a film edge may travel and intersect the light passing from the first polarising means to the second polarising means and each photo-electric cell being connected to the integrator so that when the cell is activated by light a signal is conveyed to the signal integration. In the embodiment shown four festoon-type lamps are used as the light source and thirty-two photo-electric cells are used, arranged in eight rows of four, transverse to the direction of travel of the film, with each row staggered (Fig. 3,) with respect to adjacent rows. Each photo-electric cell is connected between positive and negative voltage sources 21 and 22 Fig. 4, via a load resistor 23. Each load resistor controls the grid potential of a gas filled triode trigger valve 20, each valve having its cathode connected to one end of a recording ammeter 8. As the film 2 passes between the source and the cells it causes the light passing through it to be elliptically polarised, which light is then passed by the second polarising means 19 to activate a number of cells representing the degree of insertion of the film into the detector heads. Each cell so energized causes a potential rise across its load resistor 23 and trigger its associated valve 20. A current is thus passed through, and recorded by the ammeter 8, representative of the width of the film 2. Specification 627,228 is referred to.
