Title: Facsimile Apparatus
IPC: H04N1/00
Filed: 1966-07-12
Abstract: 1,159,402. Signalling over telephone circuits.; copying by scanning. XEROX CORP. 12 July, 1966 [14 July, 1965], No. 31353/66. Headings H4F and H4K. Facsimile apparatus for transmission and reception is coupled acoustically to a telephone line for transmission over the hand set of a substation circuit, signals being transmitted as tones. Whereas the coupling for transmission over the handset is acoustic the coupling for reception may be acoustic or inductive. A connection over the telephone system is obtained by dialling in the normal manner and the subscribers, by agreement, couple their handsets to their facsimile transmitter/receivers, one being set to receive and the other to transmit. Since, in comparison with a leased line, the connection is charged according to the length of time employed, and since with typewritten documents the spaces between lines contain no information, the transmitters are arranged to step over entirely blank scans at high speed and, when a scan encounters information, to step at a slower speed: this feature being described in Specifications 1,154,531 and 1,159,401. The unit for coupling with the handset may be separate from or integral with the facsimile transmitter/receiver when these are combined in a single casing. As shown in Fig. 2 a document to be reproduced is fed between rollers 25, 26 and 27, 28, to pass a slit 33 illuminated by lamps 31. A mirror 38 scans the slit and projects a beam through lens 40 and apertured screen 41, 42, to a photomultiplier tube 43 which generates the signals for transmission. The mirror scans at a fast rate and the receiver copy merely advances without movement of the marking head until a line containing information is encountered when the line is scanned at normal speed with the mirror working in synchronism with the marking head at the receiver. The receiver has a marking head 53 and the paper is fed over the top of drum 51 and emerges from a slot 15 beneath the drum. The paper may be securely wrapped as an endless web about the drum 51 and the transmitter document transport and the recording drum may be driven by a single motor, Fig. 3, not shown. The transmitter document transport and the receiver document transport may be combined and use a single drum such as 5 1 . The transport carriage carries a lamp, lens and photomultiplier for transmission and has a marking pen for reception: Fig. 4, not shown.

Title: Ternary recording and reproducing apparatus
IPC: G11B5/02
Filed: 1964-08-04
Abstract: 1,060,250. Recording and reproducing ternary data. STANDARD TELEPHONES & CABLES Ltd. Aug. 4, 1964 [Aug. 2, 1963], No. 31493/64. Heading G4C. In an arrangement for recording ternary data, a " 2 " is represented by a reversal of magnetization in one direction, a " 1 " by a reversal in the opposite direction, and a " 0 " by the absence of reversal. As shown in Fig. 3, for recording ternary data on a magnetic surface shown as a drum 7, although a tape may be used, a three-level ternary input signal at 2 is sensed at 1 to produce a positive pulse on a lead 3 to represent a " 2," a positive pulse on a lead 4 to represent a " 1," and no output to represent a " 0." The signals on leads 3, 4 are gated by clock pulses read from a clock track 8 on the drum, the " 1 "- and " 2 "- representing pulses so produced being effective to set or reset respectively a flip-flop 12 which is triggered by an input 13 to the opposite state half a digit period later if a " 1 " or " 2 " is to be recorded, the recording being effected by an amplifier 21. If a " 0 " is to be recorded, the flip-flop 12 is not set or reset in response to the input digit, and the trigger input at 13 is inhibited by a monostable circuit 15. There is thus no change in the magnetization state when a " 0 " is recorded. Recorded data is read by a head 25, the positive and negative signals read amplified, discriminated and squared to produce corresponding outputs on leads 31, 32, these outputs being gated by clock pulses read from the clock track 8 to produce " 2 "- and " 1 "-representing signals at 41, 42 respectively. The occurrence of neither positive nor negative output from the drum, together with a clock signal, is detected by an AND gate 35 to produce a " 0 "-representing output at 43.

Abstract: 1510785 Spacing sheet material METAL BOX Ltd 15 July 1975 [19 July 1974] 32033/74 Heading B8B Apparatus for varying the spacing of sheet material moving along a conveying path comprises fast and slow endless conveyers which meet at a junction and carriage means movable to displace the junction and so effect a more rapid transfer of sheets from one conveyer to the other. As shown a more rapidly moving set of conveyer belts 4 forms the upper run of a conveyer assembly up to point 6 on a reciprocable carriage 8 whilst a slower set of belts forms the upper run downstream of point 6. Carriage 8 normally moves downstream synchronously with belts 2 but upon detection of the arrival of a sheet at point 6 the carriage is rapidly moved upstream to effect transfer of the sheet and then resumes its synchronous movement downstream. The sheets are thus spaced from one another by a desired constant interval which depends upon the stroke of the carriage. In an alternative form (Figs. 1-3, not shown) the provision for moving the carriage synchronously with the slow belts is dispensed with and sheets are transferred from slow belts to fast belts so as to increase the spacing therebetween to a valve dependant upon the stroke of the carriage.
