Patent GB-1374974-A (GB)
Title: Device for recording images
IPC: H04N1/29
Filed: 1970-10-30
Abstract: 1374974 Facsimile-type system AGFAGEVAERT 28 Oct 1971 [30 Oct 1970] 51779/80 Heading H4F Successive lines of a television-type video signal are recorded on an insulating recording paper (moved by a step motor) by means of a linear array (e.g. 600) electrostatic recording electrodes, each elemental video signal corresponding to an elemental image area being stored in a respective memory unit, the sampling being effected by means of a shift register. In this manner the voltages corresponding to the elemental video signals from a line are applied to the recording electrodes for a television field scanning period (this enables an interlaced television signal to be recorded). The video signal may be converted into a digital signal before it is sampled and each sample stored.

Abstract: 1,086,663. Selective signalling; mask matching. WESTERN ELECTRIC CO. Inc. Dec. 23, 1964 [Dec. 24, 1963], No. 52204/64. Headings G4H and G4R. A character or pattern is selected from an array of characters or patterns by energizing the appropriate combination of a seriesarranged set of birefringent crystals to there by project a beam of light upon the selected character or pattern. In one embodiment characters selected by the output signals from a computer are recorded upon photographic film. In a second embodiment the patterns on a mask are sequentially projected on to an unknown pattern so that by photo-electrically sensing the amount of light not blocked by the unknown pattern that pattern which provides the best match can be determined.

Title: Time-monitoring device
IPC: G07F17/24
Filed: 1973-11-09
Abstract: 1409212 Parking meters VDO ADOLF SCHINDLING AG 9 Nov 1973 [21 Nov 1972] 52218/73 Addition to 1390143 Heading G4V The coin freed time monitoring device of the main patent, such as for a parking meter, has an additional locking arrangement 34 to prevent fraudulent action by the insertion of perforated coin-like objects or tokens, comprising a locking element 35 operatively connected directly or through a locking lever 30 with the double-armed lever and a sensing pin 36 movable in direction B out of the coin transport path and also pivotable about an axis 44 transverse to this path. As shown, the locking element 35 is mounted on a leaf spring 38 attached to the guide plate 13 and projects through an aperture 37 in the plate 13 to engage the locking lever 30. The spring 38 also mounts a shaft 41 which is bent to form the pin 36. When a non-perforated coin is inserted, pin 36 is deflected along B, element 35 releases the locking lever 30 which can then pivot as the coin moves onward to release the feeler pin 26 and set a time period as described in the main patent. If a coin or token with a hole is inserted, the leaf spring 38 snaps back as the pin 36 enters the coin hole and the element 35 prevents pivoting of lever 30. As the perforated coin or token is carried on the guide plate 13, the shaft 41 rotates about the axis 44 against the force of a returnspring 43 to release the pin 36 from the hole in the coin or token without disengagement of the locking element 35 and without setting a time period.
