Patent GB-340281-A (GB)
Abstract: 340,281. Ticket-printing machines. ERICSSON TELEPHONES, Ltd., 67, Kingsway, London, and ENGBLOM, J. F. T., Villa Temoana, Elm Avenue, Beeston, Notting- hamshire. Sept. 21, 1929, No. 28647. [Class 100 (iv).] Relay type-wheel actions.-An electrically-operated ticket-printing machine incorporates electromagnetic mechanism which is adapted to operate until wipers associated therewith reach a position in their contact banks marked by a manually operable switch to select a character corresponding to said position, characterized in that any one of a plurality of positions in said banks can be marked over a group of line conductors less in number than said plurality by means of a coding system. The arc F carrying printing characters is fixed by arms E, E to the shaft A which has fixed to it the ratchet B rotated one step at each actuation of the electromagnet J through the armature K and pawl L. Also fixed to the shaft A by the arms G is the arc H carrying characters one of which, corresponding to the character on the arc F in the printing position, is observed through the window P in the casing Q. The shaft A is returned to zero by the action of a restoring spring on actuation of the pawl R by the release electromagnet M. Fixed to the shaft A are the wipers C which sweep over the contacts D, D. For a one-digit scheme of printing characters there are four wipers and four arcs of eleven contacts each shown at C1, C2, C3, C4 and ADM1, ADM2, ADM3, ADM4, respectively in Fig. 3. Depression of one of the keys 0 to 9 connects an earth potential E to one or more of the line conductors 1, 2, 3, 4 thus actuating over the normally closed contact A1, the electromagnet ADM shown at J in Fig. 1, which rotates the ratchet B, arcs F and H, and wipers C1 to C4 step by step until the wipers arrive at a set of contacts, corresponding to the key depressed, such that the circuit between the potential E and the electromagnet ADM is broken. The mechanism is restored to normal by a release key REL over a circuit earth, REL, electromagnet RM shown at M in Fig. 1, B to earth. The condenser resistance circuits P, Q and C, R are spark-quench circuits. The mechanism described can be duplicated for a two-digit scheme &c. The keys 0 to 9 may have numbered thereon or adjacent thereto corresponding numbers, which may be illuminated by lamps adjacent to the keys, or by small lamps enclosed in the bodies of the keys and adapted to show through transparent material in the heads of the keys. In the above construction the marking of the required set of contacts depends upon the absence of electrical potential thereon: it can, however, be made to depend upon the presence of potential, e.g. the mechanism could be arranged to hunt until all its wipers found an earth potential, when a relay or relays could operate to disconnect the electromagnet.

Abstract: 426,505. Television. TEDHAM, W. F., 267, Woolwich Road, Abbey Wood, London. Dec. 6, 1933, No. 34346. [Class 40 (iii)] An image of an object 15 is continuously projected, as by a lens 14 and mirror 13, onto a mosaic screen of photo -electric elements 6, and the screen is scanned by a light spot preferably derived from the movement of a cathode ray beam 10 over a fluorescent screen 9. The scanning beam causes saturation emission of electrons from each element 6, which pass to the anode 7, bringing each element 6 to the potential of the anode, e.g. 20 volts. When an element 6 is illuminated by the light from the object only, the electron emission decreases and the electrons leak through a semi - conducting layer 5, e.g. aluminium oxide, to the plate 4. The current through resistance 17 produced by the scanning action provides the output for amplification and transmission.
