In an electrostatic copying machine an original is fed between arcuate guide members 74, 78 to a first of three pairs of driven rollers 50-51, 52-53, 54-55 defining a horizontal path. After passing through the roller pair 52-53, the original enters an area 36 illuminated by a lamp 118 and a 1:1 image of the original is projected on to a photoconductive copy sheet from roll 168 by means of an adjustable mirror 130 and a lens system 156. The leading edge of the original engages a switch 294 disposed in the horizontal path to energize the copy sheet feeding mechanism and then subsequently a switch 302 which prepares a circuit for actuating a copy sheet cutting mechanism the circuit being completed by the restoration of the switch 294 after the passage thereover of the trailing edge of the original. By this means the length of copy sheet can be made equal to that of the original. The severed copy sheet is fed by vertically disposed pairs of rollers 100-101, 102-103, 104-105 at the same speed as the original, passing through a charging station 108, exposure station 38, developing bath 48, drying area 230 to emerge at exit slot 236.

Title: Film Oxide Resistive Layers.

Filed: 1966-11-03
Abstract: 1,166,285. Resistors. SOC. D'ELECTRONIQUE ET D'AUTOMATISME. 3 Nov., 1966 [8 Dec., 1965], No. 49348/66. Heading HIS. [Also in Division C1] An oxide film resistance element comprises a layer of non-stoichiometric tin oxide bonded to an insulating substrate, the resistivity of the material of the film decreasing continuously from the substrate surface outwards either to a point intermediate the surface of the film and the substrate (after which the resistivity may increase) or to the film surface. The film is formed by spraying solution from containers 1 and 2 through an atomizing jet 4 on to a heated substrate carried on plate 7 (which may be rotated) in an oven 6 maintained at a predetermined temperature (550-600 C.). Container 1 holds an oxidizing reagent (zinc oxide), tin chloride and a doping impurity (aluminium chloride) in distilled or de-ionized water mixed with hydrochloric acid. Container 2 contains a similar solution without the oxidizing reagent. To begin only the solution from container 1 is used the mist produced forming a high resistivity tin oxide layer on the substrate by pyrolytic dissociation. Mixer cock 3 is then moved so that an increasing quantity of solution from container 2 with a correspondingly decreasing quantity from 1 is delivered to jet 4 to produce a progressive reduction in the resistivity of the oxide deposited on the substrate. The resistivity is arranged to fall from a peak at the substrate surface to a low level at the surface of the finished film or at a point within the film from which it may increase to another peak which may be at the film surface. The solution is forced from containers 1 and 2 by air pressure under control of cock 11. Switch 13 controlling a motor 12 operating cock 3 may be linked mechanically to cock 11. The rotation of motor 12 or of cock 3 may be controlled in accordance with a required programme.

Title: Improvements in or relating to high-speed cameras
Inventor: HUSTON ALEXANDER EDWARD

Filed: 1966-11-03
Abstract: 1,143,444. High speed television camera; staircase waveform generating circuits. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 19 Oct., 1967 [3 Nov. 1966], No. 49402/66. Addition to 1,016,930. Headings H3P and H4F. Relates to a waveform generations circuit for the high-speed camera described in the parent Specification, the waveforms which are generated being applied to two pairs of deflector plates 3 and 4 in the camera so that an electron image of a phenomenon is swept across an aperture plate 2 by deflector plates 3 to produce a shutter action and the electron image which passes through the aperture is swept in the opposite direction by plates 4 (compensating plates) to immobilize the image. The waveform generating circuit comprises a parallel resonant circuit formed by inductors L1 and L2 connected in series by a thyratron 6 constituting a triggerable switch, and capacitors C1 and C2 connected in series, their junction being connected to a reference potential (earth). The capacitors are charged symmetrically via high-value resistors R1 and R2, and the voltage across C1 and C2 in series is applied directly to shutter plates 3, and with opposite polarity to the compensating plates 4, resistors R3 and R4 providing the necessary small phase displacement between the shutter and compensating waveforms. To take a sequence of photographic frames, thyratron 6 is triggered and C1 and C2 discharge through L1 and L2 in series. The resonant circuit goes into damped oscillation, and the oscillatory voltage is applied to the deflector plates to provide shutter and compensating action as described in the parent Specification. Only the first few cycles e.g. eight cycles for sixteen frames, are used for shutter action, by which time the maximum stepwise shift of the beam has been applied by plates 5 as described in the parent Specification. The stepwise shift " staircase " waveform is derived by means of a circuit including tetrode 8, the grid of which is DC biased beyond cut-off via resistor R6, and a winding L3, coupled to L2, is connected to apply a signal between grid and cathode via the D.C. blocking capacitor C7. When thyratron 6 is triggered, a sinusoidal voltage is induced in L3 whose positive halfcycles are sufficient to overcome the bias on tetrode 8 and bring it into conduction. During each conducting period the anode voltage falls and the cathode voltage rises by a constant amount, providing a push-pull staircase waveform which eventually reverses the D.C. voltages initially applied to the shift plates 5 via resistors R9 and R10, thereby progressively displacing each successive pair of frames across the screen.

Abstract: 1,199,788. Disc brakes. BUDD CO. 2 Nov., 1967 [2 Dec., 1966], No. 49881/67. Heading F2E. In a ventilated disc brake for a railway vehicle wheel 16 having a braking disc 17 constructed of vanes 31 between two plates 27, 29 so as to cause outward flow of cooling air when the disc is rotated, the air flow is controlled by a cylindrical shutter 43 which is movable axially by an actuator 45 between a first position (Fig. 1) in which it blocks the flow and a second position (Fig. 2) in which it allows the flow. On applying the brake pads 21, 22 to the disc 17 air is admitted via input fitting 81 of the brake actuator 25, air line 77 and rotary fitting 79 to cylinder 57 so that the shutter 43 is moved axially to allow cooling air to pass through the disc 17. When the brakes are released a delay valve 83 delays the return of the shutter 43 to the closed position so that cooling air continues to pass through the disc. The shutter 43 is returned by springs 71 to the closed position after braking so as to avoid power loss due to the cooling arrangement.
