Title: Printer input queuing arrangement for latent image printers
IPC: B41J5/44
Filed: 1972-06-15
Abstract: 1389060 Printers STANDARD TELEPHONES & CABLES Ltd 15 June 1972 28171/72 Heading G4H A latent image printer 4 has an electronic queueing store 2 and a tape store 6, the two stores having a common input terminal 1, data items from 1 normally passing immediately through the queueing store 2 to the printer. 4, but after a break in availability of the printer, data items are taken from the queueing store 2 only, if the number of items which arrived during the break did not exceed its capacity, while if the number did exceed its capacity the excess first arriving items are taken from the tape store 6 and the other items are taken from the queueing store 2. Each data item from 1 is entered into both stores 2, 6, that entered into store 2 passing to the left-most vacant position, the tape 6 normally being taut with a storage capacity of N 0  data items, the capacity of store 2 being N 0 +Ns where Ns is zero or a positive integer. An item is read from store 6 as each new item is entered, to keep the tape taut .but this iten read out is not normally passed to the printer 4. If there is a break is availability of the printer, read out from store 6 will be stopped after read out from it of N 0  data items after the start of the break (assuming the break is at least that long). Store 2 is not read out during the break at all. If store 2 fills up completely during the break, the full state of the right-most stage 2a is detected at 22 to cause the contents of the left-most stage 2z to be deleted (so that-other contents move leftwards), After the end of the break, store 6 feeds the printer with all the items (if any) thus deleted from store 2, then store 2 feeds its contents to the printer. These operations are controlled by counters 7, 8, 9 counting respectively Np (the number of data items passed to the printer), Nq (the number of items put out from store 2), Nr (the number of items put put from store 6), and difference units 10, 11 measuring the differences Nq-Np and Nr-Np respectively. However, the counters 7, 8 are kept equal, e.g. at 0, by unit 29 as long as stage 2z of store 2 is empty, and counter 8 is kept N 0  greater than counter 9, by unit 30, e.g. by holding counters 8, 9 at 0, -N 0  respectively, as long as stage 2z is empty and the tape. 6 is tight. The printer 4 prints by recording a latent image on a first surface then developing it and transferring it to a second surface where it is fixed. The process may be ferrographic or electrographic.

Title: Improvements in or relating to processes for the manufacture of light sensitive layers for colour photography
IPC: G03C7/26
Filed: 1929-09-17
Abstract: 340,278. Plates and films for colour photography. HEIDE, E. WOLFF-, 16, Kopenhagenstrasse, Berlin. Sept. 17, 1929, No. 28206. [Class 98 (ii).] Light-sensitive negative material for subtractive work comprises a single light-sensitive layer which is treated so as to divide it into three colour-sensitive regions from the bottom surface to the top. An ordinary emulsion layer is treated with a colloidal solution of pinaflavol or other green sensitizer for a time sufficient to allow the dye to penetrate to the intermediate portion of the layer. After drying, the layer is treated with a colloidal solution of pinacyanol or other red sensitizer, for a time sufficient to allow the dye to penetrate into the surface portion only. After drying again, the whole layer is treated with an orange dye which will absorb blue and green rays but will transmit red rays. The colloidal sensitizing solutions penetrate into the emulsion layer with difficulty, and the duration of application to achieve the necessary depth of penetration is determined experimentally as by exposing trial plates. The intensity of the orange staining may be graded, so that it decreases from the top of the layer to the bottom, as by using an aqueous solution of a mixture of rapid filter yellow and rose Bengal, which penetrates into gelatine very slowly. On exposing the layer through its support to a coloured object, the blue is recorded in the lowermost portion of the layer, but is prevented by the orange filter from penetrating further. The green rays penetrate further than the blue, but are prevented by the orange filter from reaching the uppermost portion of the layer, and green is therefore recorded in the intermediate portion. The red rays pass right through the layer, and are recorded mainly in its uppermost portion.

Regulating transformers.-An appliance for electrotherapeutic treatment comprises a casing enclosing a self-induction coil in circuit with an interrupter, and fitted with externally operated means for varying the frequency and intensity of the current impulses communicated to a series of studs on the casing forming electrodes arranged in separate series of opposite polarity. Handles or other movable electrodes may also be connected to the casing by flexible conductors. In the form shown, a metal casing 1 is formed with a separate base member 2 of insulating material through which project a number of metal studs or electrodes 46, 47 of opposite polarity. The casing contains an electromagnet comprising a coil 6 (see diagram, Fig. 14) and a core 7 coacting with a pivoted armature 10 controlled by a spring 11. The moving contact 16 of the interrupter is mounted on a spring 18, which in engaged by an adjustable nut 24 on a rod 23 carried by the armature 10. The leads to the electrodes 46, 47 and to a pair of detachable electrodes 50 are connected to binding posts 42, 43 connected respectively to the interrupter contacts 16, 17. The speed of the interrupter is varied by turning a button 31, the stem of which carries a cam 35, Fig. 14, which bears against the armature 10 to limit its movement away from the core 7. The intensity of the current impulses in the electrode circuit is varied by turning a button 54 which is connected to a contact 57 travelling on a rod 60 and engaging a coil 53 of thick wire which surrounds the inductance winding 6 and is wound in a direction opposite thereto. The induced current in the coil 53 sets up, through the medium of its own magnetic field, a counter current in the inductance winding which serves as an impedance which may be regulated by more or less short-circuiting the coil 53 by adjustment of the contact 57. The primary circuit of the electromagnet is connected through a socket 14 on the casing and a plug terminal, Fig. 12, to a battery and is controlled by a press-button switch 30 on the casing.
