Class 100(2) [Also in Group XX] A xerographic printing process comprises covering the image surface of an electromatically charged and exposed photoconductive plate with a light-excluding screen, placing the non-image surface of the screened plate on a flat metal earthed member resiliently supported in a printing box, placing an image-recording sheet over the screen, closing the lid of the box to exclude light, at least one resilient pad on the lid contacting the screen and removing the screen to allow contact between the recording sheet and the image surface, pressure between which causes image transfer. A metal support 1, Fig. 1, having a film 2 of selenium deposited thereon is mounted in a frame 3, where it is charged, exposed and developed, being then recharged in the dark, an opaque screen 6 then being pushed through a slot 4 and along channels 5 so as to protect the film from light. A printing box comprises a base 7, Fig. 2, supporting a layer of resilient material 9 covered with a sheet 10 of metal, which is or can be earthed through a lead 11, and a secured lid 12 carrying four resilient pads 13 hinged to the base. The assembly 1, 2, 3, 6, Figs. 1 and 3, is placed on the plate 10, a metal image recording sheet 14, e.g. a lithographic printing plate, is placed on the screen 6, and the lid is closed. The screen is then pulled out, the pads 13 forcing the sheet 14 into contact with the film 2 to receive a print therefrom

As shown, the capsule consists of a bottom tube 1 and a closure part 2 having an axial plug 4 which is screwed, at 7, into the tube 1 to form the cavity 3 in which the emitter 6, consisting of a radioactive isotope, is inserted, an annular groove 5 being formed between the assembled parts 2, 3. A longitudinal groove passes through the threads of the plug and extends from the cavity 3 to the annular groove 5, the longitudinal groove and the cavity 3 being filled with an organic substance which is permanently solidified by the emitter 6, or by a separate emitter, to seal the parts 1, 2 together. The part 2 has a tapped hole 9 which serves for the detachable fixing of a capsule carrier, and the part 1 has flats 8 adapted to be engaged, e.g. by a spanner. An example of an organic sealing substance is given as a mixture of trichloromethylsilane, dichloromethyl-silane, and precipitated silicon dioxide.

Title: Improvements relating to digital-to-a-nalogue converters
Inventor: FLOOD JOHN EDWARD
IPC: H03M1/00
Filed: 1958-12-23
Abstract: 867,394. Electric selective signalling systems. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Dec. 22, 1959 [Dec. 23, 1958], No. 41563/58. Class 40 (1). A digital-to-analogue converter comprises an individual capacitor for each digit of a binary code, means for distributively applying incoming digit pulses to charge the capacitors proportionately to the significance of their associated digits, and means actuable subsequently to the receipt of all the pulses to connect the capacitors so that a resultant analogue output is proportional to the sum of their charges. A binary digit represented by the presence or absence of a negative voltage is applied to a normally grounded input tm as a further negative potential is applied to a normally grounded input t. The diodes G1m, G2m are "backed off" to allow a condenser Cm to charge to a potential - Vm (through a resistor Rm and a diode R#1m from a negative supply line l) where it is held by a diode R#2m conducting. Similarly other digits are represented by charges on other condensers e.g. Cn; the charge on each condenser is arranged to be proportional to the denomination of its associated digit. The application of a pulse to an input tx " opens " the transistors TRm, TRn . . . to produce a voltage at o representative of the binary input. The condensers are discharged by applying a pulse to an input td to " open " a transistor TRd to earth. The pulses may be applied simultaneously or successively to the inputs tm, tn . . . , the signal on input t being adjusted accordingly. In a modification the maximum charge on a capacitor is partially governed by charges upon higher denominational capacitors to produce an output which may be some prearranged function of the binary input.
