Title: System for analysing and storging telegraph characters received on several lines
IPC: H04L12/52
Filed: 1973-12-14
Abstract: 1450428 Telegraphic exchanges INTERNATIONAL STANDARD ELECTRIC CORP 14 Dec 1973 [21 Dec 1972] 58017/73 Heading H4P In a telegraphic switching centre, e.g. an automatic exchange comprising an independent and separate transition detector and character reconstituting (or line) block in which characters are then stored in a waiting queue together with identity of the line, and which are subsequently read by a CPU which reconstitutes messages, analyses their content and addresses, and which are stored in a memory for retransmission on an appropriate outgoing line, load is taken from the CPU by an additional and separate unit which analyses and stores the received characters. The unit (or character block) is arranged between a CPU and one or more line blocks from which characters in the queue are read and then stored in buffer stores, analysis being made during the transfer. A sequence unit, provided with memory accessing, also write in and out means, take a character and line identity from the queue, address one of a plurality of line memory cells to gain access to a designated buffer store and place therein the character for action by the CPU. A line block BL periodically examines states of incoming lines lg, each transition causing particular processing aimed at reconstituting characters CAR which are stored together with line identity in a memory cell, e.g. fa of waiting queue FAR. The character block BC reads out and analyses the content of CAR to detect if it belongs to a significant message part, e.g. a heading, for which purpose a memory cell MLX is consulted. In this cell are stored an indicator PH and an address ACMT allotted to the line NL. PH and CAR address a translator TR which provides a new position PH<SP>1</SP> and a possible SIG signal which is stored in a memory cell of waiting queue FASR accompanied by NL. In other respects BC stores CAR in a cell of MT defined by address ACMT. Simultaneously BC replaces PH by PH<SP>1</SP>, also the ACMT address is indexed before being re-stored in MLX. BC can now read out another character from queue FAR. Signals resulting from analysis determines switching operations concerning message routing towards outgoing lines hence central processing unit BC is freed from analysis and sequential storage operations. More detailed operation of circuit parts is described with reference to Figs. 2-10 (not shown).

Abstract: 1357629 Electrostatic printing MITA INDUSTRIAL CO Ltd 29 Dec 1971 [29 Dec 1970] 60530/71 Heading G2H [Also in Division B6] Electrostatic printing is carried out by forming an electrostatic image on a surface 4, suitably by electro-photographic means, and developing it with a toner 6 whose particles have a charge of the same polarity as that of the latent image, then contacting the surface 4 with an imagereceiving member 7 with electrical properties so chosen as to be able to receive the toner image without dissipation or disturbance of the latent image, which can be redeveloped for making of a second toner image. A charged insulating surface 4 may be exposed to a light image, and simultaneously subjected to a corona discharge which either is A.C. or of the opposite polarity to the charge previously given to the surface at 13. Then the entire surface is exposed to light 16, and a latent image is formed.

Title: Cinematographic reproduction apparatus
IPC: G03B1/56
Filed: 1970-12-21
Abstract: 1339907 Cinematographic control devices AGFA-GEVAERT A G 21 Dec 1970 [20 Dec 1969 (2)] 60671/70 Heading G2E A cine projector for use with films having leader and/or tail sections whose transparency differs markedly from the remainder of the film incorporates switching device(s) operating in response to the change of transparency between the leader or tail sections and the remainder of the film. As shown the projector 1 receives a cassette 2 from which film strip passes to take up reel 5. Above the picture gate 13, aperture 15 permits light from source 4 to fall on a light sensitive device viz photo-resistor 17 after passing through the film. Leads 18, 19 connect the photo-resistor 17 to control device and leads 22, 23 connect the latter to electromagnet 21. The differences in transparency between the lead and tail sections and the remainder of the film define two mutually exclusive ranges of signal acting on the photo-resistor 17, Fig.2, 3 (not shown) disclose respectively transistor and thyristor switching circuits whereby the electromagnet 21 is energized when the lead in or tail section of the film is over the aperture 15. Energization of the electromagnet 21 pushes rod 25 against the compression spring 27 so that lever 33 is pulled under the action of spring 34 to place drive wheel 36 in direct contact with the spool 5 so that the film passes through the picture gate at a high speed. When the remainder of the film is over the aperture 15 the electromagnet is de-energized and the rod 25 moves from the position shown so that a projection thereon abuts the stop 28. As a result lever 33 moves drive wheel 36 to contact wheel 39 and hence drive spool 5 via wheels 40, 48 at a second-slower speed (i.e. for projection), projection 30 causes film transport claw 41 to be moved into its operative position, projection 31 moves the arm 45 about its pivot 46 so that drive wheel) contacts the film, intermediate lever 48 connected to arm 45 removes the objective cover 49 and moves film pressure plate 14 into contact with the film. In another embodiment, Fig.4, 5, 6 (not shown) a retarding circuit incorporating a mechanical film sensor delays the change in film transport speeds so that the change is co-ordinated with the change of film transparency opposite the picture gate rather than occurring immediately. The control mechanism of this embodiment includes a circuit which is able to cause reversal of the film and switching off of the light source 4 when the toil section of the film passes between the source 4 and the photo-resistor.
