Title: Horizontal tabulation apparatus for office machines
IPC: B41J21/08
Filed: 1974-06-05
Abstract: 1428640 Typewriters ING C OLIVETTI & C SpA 5 June 1974 [12 June 1973] 24964/74 Heading B6F Tabulation mechanism comprises a plurality of sensing elements such as 28a, 28b individually settable to first and second positions to define collectively a tabulation position of a typewriter carriage, a plurality of cams such as 101-104 arranged to be driven in sympathy with the carriage, the cams being arranged in groups successively driven at a submultiple of the speed of the preceding group, the cams of each group defining in cyclic sequence a succession of code combinations, the sequence being the same for all groups, the sensing elements being associated in groups corresponding to the groups of cams and the elements of a group defining a selected one of the code combinations, and the sensing elements co-operating with the cams and controlling a stop mechanism so as to stop the carriage when the code combinations of the sensing elements and the cams match. Each sensing element 28a &c. is positionable by a respective electromagnet 3a, 3b ... to co-operate with one of a pair of complementary cams 101, 102; 103, 104; .... Further electromagnets 3g, 3i, (3h, Fig. 3, not shown), control the direction of tabulation, the start of a tabulation cycle, and a rectifying displacement of the carriage to one side or other of the tabulation position defined by the sensing elements 28a, 286 ... respectively. Energization of electromagnet 3i couples a shaft 13 with a driven shaft 15, whereby a face cam 22 is rotated. A spring 20 thereby tries to urge the sensing elements 28a ... into recesses in the selected respective cams 101 ... , but no movement occurs until the cams are all positioned in the necessary code combination. Simultaneous energization of electromagnet 3g acts to couple a sleeve 74, and thereby a driven shaft 86, with either of two gears 81, 82 to determine the direction of drive of the cams 101 ... and of a shaft 41 which drives the typewriter carriage. When the cams are positioned such that the sensing elements 28a ... can all move rightwards simultaneously, a sleeve 32, 33 on shaft 41 is displaced leftwardly to couple one of two pins 38 in a barrel 40 fixed to sleeve 32, 33 with a shoulder 55 or 55a on a slide 42. The slide 42 acts on a bail 65a to rock the sleeve 74 out of engagement with gear 81 or 82 and thereby disconnect the drive to the carriage. The shaft 13 continues to rotate, resetting the sensing elements 28a ... and also through a cam 122 or 123 turning the shaft 41 and thereby displacing the carriage by a rectifying amount in a direction determined by the position of a sleeve 136 set by the rectifying electromagnet (3h).

Title: Slow wave circuit and tubes using same
IPC: H01J23/24
Filed: 1966-06-08
Abstract: 1,145,070. Slow wave structures. S-F-D LABORATORIES Inc. 8 June, 1966 [11 June, 1965], No. 25585/66. Heading H1D. A microwave tube apparatus comprises a slow wave circuit formed by an array of conductive vanes 2 projecting from a conductive wall structure and having free front and side portions, which define an array of cavity resonators, together with one or two conductive members, e.g. 9 and/or 11, overlying and spaced from the side edge portions of the vanes and which form the ground plane of the circuit, and a cathode 5 which produces an electron beam adjacent the front edge of the vanes for cumulative interaction with an r.f. wave in the slow wave circuit. The spacing between the cathode and vanes is greater than the spacing between the conductive member and the side edges of the vanes, and the conductive member either extends only over a part of the side edges of the vanes as shown in Fig. 7, or are closer to the vanes over this part than over those parts nearer the roots of the vanes, e.g. Fig. 14 (not shown). Thus the spacing between the cathode and the vanes may be fixed at its optimum distance and the slow wave circuit capacitance to be increased and particularly controlled by the conductive members to provide an increased forward fundamental mode electronic band width at lower operating voltages. The conductive members 9, 11 may be spaced from the vanes by dielectric slabs or may be conductively supportd from the vane support 12 and may be L-shaped in cross-section. Fig. 20 illustrates a C-band crossed-field amplifier in which the L-shaped conductive members 9, 11 are copper annuli brazed to the support 12 to which is also attached a partially annular array of T-shaped vanes 2. The emitter is a cold cathode 5 coated with beryllium copper and disposed coaxially of the vane array. Two waveguides 32 separated by a metallic sector provide input and output connections to the slow wave circuit and the matching network couplings may be coaxial-line, in which the central conductor is connected to an end vane at its mid-height, or may be strip-line, in which the end vane, provided with a mid-height notch forming an H-plane power divider, is extended to conductively interconnect the conductive members 9, 11, Figs. 16-19 (not shown).

Abstract: 983, 776. Magazine tapes; rewinding. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. June 28,1963 [July 3,1962], No.25819/63. Heading G5R. To prevent an over-sized tape-mouse 9 from being slammed against a tape-magazine mouth, whatever the state or speed of rewinding, a tape mask 8 or 22 actuates stop means automatically followed by restart means in the spool-drive so that the final rewind is slow. In Fig. 1, an actuator 1, started by rewind switch 2 engages a drive transfer to the reel until a foil 8 bridges contacts 6 to short-circuit the actuator 1. A slow-to-release relay 5 then opens contact 4 and its inertia provides a sufficient delay to allow the tape to stop, with or without automatic brake assistance. The foil 8 having passed the contacts 6, the eventual closure of contact 4 restarts the drive. In Fig. 2, a transparent leader 22 allows the illumination of a photo-resistor 17 to apply a trigger pulse to a previously-immobilised multivibrator 10, whose relaxation period switches current off and on again through an actuator 13 engaging the drive-transfer to the reel, rewinding having been started by switch 12. Contact means in the magazine, opened by the arrival of the mouse 9 may be arranged in series with the switches 2 or 12 to disconnect the drive when rewinding is completed.
