The oscillator 1 is switched off by a switch 13 which disconnects the supply 16 from the oscillator, and connects it, via line 15, to charge integrator capacitor 18 to a potential which will cause varactor 7 to tune the oscillator to a frequency lower than the natural frequency of the transducer.

A display tube comprises a cold cathode including a plurality of P-N junctions 21b, 21c, 21d each with an exposed edge in the form of a character or a part thereof which emits electrons when energized, conductors for selectively energizing the junctions, a fluorescent screen and an electron optical system for projecting an image of the junction on to the screen; The cathode of SiC or GaP comprises a P-type layer produced by diffusion or epitaxial growth on a layer 19 comprising N-type regions 25a, 25b separated by high resistivity regions 23a, 23b formed by diffusion of accepter impurities into layer 19. Grooves 27a, 27b divide the layer 17 and with regions 23 result in a matrix of isolated junctions.

Abstract: 1340200 Mould closing device MASCHINEN-FABRIK UND GIESSEREI NETSTAL AG 23 Dec 1970 [23 Dec 1969] 61246/70 Heading B5A The movable platen 8 of an injection moulding press is displaceable, along the bars 2, towards and away from a fixed platen 3 over a mould closing distance a, by means of a crank connection 6b, 6a, 5b actuated by a rotary piston drive 7 within a housing 5a, and a mould clamping force is applied to the platen 8 over a distance M1 by a linearly displaceable double acting differential piston 4b which acts on the housing 5a. The piston drives 7, 4b, are of adjustable stroke. The distance M1 is set, e.g. from 0À1 to 0À2 mm., by an electrical contact E1 which is actuated by the platen 8 to cause switching from the hydraulic drive 7 to hydraulic drive of the piston 4b, and when the mould clamping force is released by retracting displacement of the piston 4b over a distance R, a switch E4 is actuated to cause switching from the hydraulic drive of piston 4b to the hydraulic drive 7 to effect mould opening displacement of platen 8. The rest position of housing 5a is determined with respect to a plane X by a pair of opposed springs 13a, 13b, mounted on a positionally adjustable rod 64, which act on a cylindrical member 11 connected to the housing 5a at an arm 9. If closing movement of the platen 8 is obstructed over the distance M1, the crank drive 6b, 6a acts to displace the housing 5a instead of the piston 5b over a distance M2 so that the spring 13a is compressed and one side of a cam 10 carried by the arm 9 halts the drives 4 and 7 by striking a locking valve 14a which also actuates a contact E2 which discontinues the supply of hydraulic fluid to the locking valve 14a. If the mould closing movement of the piston 4b occurs over too great a distance, the housing 5a is displaced around member 5b and consequential damage to the apparatus is avoided by the spring 13b being compressed, over a distance M3, so that cam 10 acts through a locking valve 14b and switch E3 to cause the hydraulic fluid supply to the drives 4 and 7 to be similarly discontinued.
Patent GB-631626-A (GB)
Abstract: 631,626. Ticket-issuing machines. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd., MASON, R., and PIGGOTT, J. Aug. 20, 1947, No. 23055. [Class 106 (iii)] A machine for printing tickets, labels, stamps, &c. includes mechanism for automatically perforating, scoring or otherwise weakening the paper strip or band along lines of ultimate severance and a member arranged to grip the strip during this operation and after the issue of the printed detachable portion so as to enable a single ticket or the like to be readily detached. A cam 5 on the same shaft 4 as the printing drum co-operates with a roller 6 and a projection 15 on a spring-urged carriage 7 pivoted about a point 8. When the printing drum and cam 5 rotate, the roller 6 is forced out of a notch 13 in the cam, rocking the carriage 7 downwards and lowering a serrated knife 21 out of the path of the ticket strip 2 which is, subsequently, printed and issued. When the projection 15 snaps over the edge 14 as the rotation of the cam 5 is completed, the serrated edges of the knife 21 pierce the ticket and a resilient block 22, normally flush with the edge of the knife, clamps the strip against a pressureplate 17. The ticket can then be torn along the perforations or, if required, further tickets may be issued in a continuous strip. Rotation of a cam 23 to engage a roller 25 and rock the carriage 7 clockwise moves the serrated knife 21 clear of the ticket strip and, releasing a locking device, allows the front plate 10 to be swung down (shown dotted) for insertion of a fresh roll of paper &c.

Title: Video signal processing for interlaced television display
IPC: H04N7/01
Filed: 1978-08-07
Abstract: Video information elements which relate to individual picture elements of an image, e.g. a radar image, of 2m rows each of n picture elements and which are stored at individual locations in a store are repetitively read out and fed to an interlaced field display device in such manner that information elements of the row corresponding to the line being scanned at any time and those of the rows on either side of this row become available simultaneously. The elements of the first-mentioned row contribute to the display uniquely unless they are such as to give rise to zero brightness, in which case they are replaced by a combination of the corresponding information elements of the two adjacent rows. This subjectively reduces the flicker of a bright area on a given displayed line if the portions of the adjacent displayed lines adjacent it would otherwise be dark, and facilitates line-infill if the number of active displayed lines is larger than 2m.
