Title: Printing machine for talking picture films
IPC: G03B27/10
Filed: 1930-04-25
Abstract: 359,916. Photographic printing apparatus. DEBRIE, A. L. V. C., 111, Rue St. Maur, Paris. April 25, 1930, No. 12811. Convention date, May 2, 1929. Void [Published under Sect. 91 of the Acts]. [Class 98 (ii).] Consists in apparatus for printing an optical sound record and kinematograph pictures simultaneously on a single film in a single operation, either from separate negatives or from a combined sound and picture negative film, the printing of the pictures being effected by a device past which the films are moved intermittently, and the printing of the sound record being made by a device past which the films are driven at a uniform speed. In the apparatus shown in Fig. 1, a combined sound and picture negative 1 and a positive print film 3 are driven together, the films being drawn with intermittent movement (by mechanism not shown) through the gate 7 of a device for printing the pictures, and thence passing with uniform movement through a gate 9 where the printing of the sound record occurs. This uniform movement is effected by a continuously-driven drum 11. Instead of arranging the sound-printing gate where shown, it may be so arranged that the sound record is printed during the passage of the films over the drum 11. Fig. 2 shows a modification wherein separate picture and sound negative films 18, 22 are printed on to a common positive film 3. The toothed filmdriving drums 19, 24, 28 may be arranged on the same shaft.

Title: Improvements in or relating to lamp black and like material
IPC: C09C1/60
Filed: 1941-10-10
Abstract: 551,862. Lamp black &c. CHAMPION & CO., Ltd., C. H., and KOPPEL, L. Oct. 10, 1941, No. 13082. [Class 90] Lamp black &c. is consolidated for convenience in handling by withdrawing the air from between the particles and bring- ing them into intimate contact with one another, optionally by applying pressure. The lamp black is charged intc a cylinder 1 fitted with a piston 3 carrying a flexible connection 4 to a vacuum pump. The entrainment of lamp black into this connection is prevented by a baffle 6 attached to the piston and spaced apart from it and having a small clearance 8 between it and the cylinder walls. As the chamber is evacuated the piston falls pressing the carbon particles into contact. Subsequently a hydraulic ram may be applied in place of the handle 16 and the lamp black further compressed into a cake, which is discharged after removing the bottom 13 of the chamber. Alternatively it may be discharged in small pieces by passage through a wire screen substituted for the bottom of the chamber.

Abstract: <PICT:0420668/III/1> In an apparatus for coating flexible sheet or strip material with adhesive or other liquid, embodying a coating roll 14 and guiding devices 24, 36 which bear upon a workpiece 84 respectively before and after it contacts with an area at the upper part of the roll and which allow of lateral introduction of the work, a drag is imposed upon the workpiece, as it is drawn through the apparatus by reason of its being lightly clamped, before it reaches the roll, at a point adjacent the end, nearest the roll, of a work table 20, over the surface of which it is drawn.  The clamping may take place between the table 20 and the member 24, the latter being carried by a pivoted arm 26.  The area of contact with the applying roll may be varied by adjusting the member 36 in the slot 40 of a pivoted bracket 38.  The edge 33 of a plate 32 serves to strip surplus adhesive from the work and also to spread evenly the coating which has been applied, while fingers 28 prevent the work, if slackened, from being drawn down into the trough 12.  Treadle devices are provided to lift the members 24, 36 while the work is being introduced, and to drop the member 24 before the member 36 is lowered.  Specifications 953/11, [Class 140], 302,958, [Class 95], and 385,975 are referred to.

Abstract: 1,089,805. Tunnel diode circuits. COMMISSARIAT A L'ENERGIE ATOMIQUE. March 29, 1966 [April 2, 1965], No. 13896/66. Heading H3T. [Also in Division G4] In a tunnel diode memory cell, the tunnel diode 4, whose anode is earthed and whose cathode is biased so that the diode has two stable states, is connected to the input 3 of the cell and also to the output 5 of the cell through two series-aiding diodes 8, 10, the common point of the diodes being connected through a charge storage diode 12 to an energization circuit for the cell. Such cells may be used to construct a ring counter or a shift register. When tunnel diode 4 is in its low-voltage state, representing " 0," a positive energization pulse at A is insufficient to render diodes 12, 8 conductive, and the cell is unaffected. When diode 4 is in its high-voltage state, representing " 1," a positive pulse at A renders diodes 12, 8 conductive and passes to diode 4 to switch it to its low-voltage state. Diode 12 stores charge from positive pulse 14 so that the negative pulse which immediately follows the positive pulse passes through diodes 12 and 10 to the succeeding cell to switch it from the " 0 " to the " 1 " state. Each cell may be provided with an output circuit 26-30 to indicate the state of that cell. Fig. 3 (not shown) depicts a device for testing the resolution time of one such cell. The device includes a pulse generator (36) the pulses from which pass to a pulse doubler (40) which produces, from the single pulse, a pair of pulses separated by a variable time interval. The pair of pulses pass through an impedance transformer (44) comprised of a number of coaxial cables and including a pulse shaper (46) and thence to the energization circuit of the cell.
