This machine is the same as that described in the parent Specification 1,167,362, but the claims are directed to a method of data processing by printing on a copy sheet e.g. a record card, 13, Fig. 3, from a master sheet 5 and also providing machine readable data e.g. punched holes P by means of a punching device 17, comprises producing a typed copy and machine readable original 1 which is sensed by reading devices 9 which controls, via a store 18 and a decoder 151, the data punched, attaching the master sheet 1 on to a duplicating machine 12, 15, and printing parts of the master sheet on the same card 13. Typewriters.-A typewriter 150 for producing the original 1 and the master sheet 5 has typelevers 3, Fig. 2, and between them and the platen and between the original 1 and master sheet 5 is a carbon sheet 4. A minor script is produced on the back of sheet 5 by a dye sheet 6. The characters may be of known CMC 7 script readable by magnetic heads or two machines coupled together may be used, one typing in ordinary characters and the other magnetic data. Duplicating machine.-The process employs known rotary duplicating machines in which the master sheet 5, Fig. 4, is attached to a printing cylinder 12 and a counter pressure roller 15 is selectively operated from a keyboard so that one, two or more lines are printed on to the copy sheet 13. The mechanism rotating the printing cylinder 12 also feeds the copy sheets 13 and also drives the sensing heads 9, 9a, 9b, in a reader unit which senses the machine readable data on the original sheet 1, which is, as shown, mounted on a flat plate 7. For accurately aligning the lines to be read, illuminated slots 10 are provided over which the original sheet 1 is clamped. A second readable sheet 1a may also be provided to control printing by a separate mechanism on the cylinder immediately in front of the printing master sheet 5. In a further embodiment (Fig. 15) the original sheets 1, 1a are clamped on a cylinder (153) arranged adjacent to and driven in synchronism with the printing cylinder. In each of these embodiments the sensing heads are moved in letter-spacing direction by a helical groove and follower and stepped for line-spacing by racks and pawls. The sensing devices may be magnetic or optical readers. Selectable data on printing cylinder.-The printing cylinder 12 may have selectable matter controlled by magnetic sensing of marks on the original sheet 1a.

IPC: H03C3/32
Filed: 1943-08-12
Abstract: 592,929. Magnetrons; frequency modulation. WESTERN ELECTRIC CO., Inc. Aug. 12, 1943,_No. 13106. Convention date, May 1, 1942. [Classes 39 (i) and 40 (v)] In a magnetron of the type in which the anode surfaces 18 are backed by a number of resonant cavities 14, Fig. 1, coupled together by end-spaces 26, 28, tuning is effected by moving a conductor, such as an end-plate 36, 38, within the end-space so as to vary the magnetic or electric coupling between the resonators. A screw 58 may be used to effect permanent adjustment of the end plates which have flexible edge connections 40, or a moving coil 64 in conjunction with permanent magnet 68 may modulate the frequency in accordance with signals. The leads 22 to the cathode 20 are brought out across the mid-plane of a resonator so as to minimize coupling between the leads and the resonator field ; energy is taken off by loop and coaxial line 48. The discharge space is closed by discs 32. The effect of moving the end-plate, which, operates mainly by varying the cross-section of the magnetic flux 56 coupling adjacent resonators, may be enhanced by attaching to it curtains of metal which hang down nearly to the block face between alternate resonators. In a modification which acts more upon the electric coupling between adjacent faces of the anode slots 16, an annulus 74, Fig. 4, may be moved axially by rod 76 and flexible joint 78 toward or away from the region of the slots 16. The annulus may be slit as shown to allow it to pass the lead 22 and is connected at 80 to the anode block. The whole device may be enclosed in an evacuated vessel. The cathode may be self-heated during operation.

Patent GB-134200-A (GB)
IPC: G03F7/20
Abstract: 134,200. Schulze, A. May 18, 1918, [Convention date]. Cheques and the like.-A method of producing guilloches and like designs, more especially for currency-note engraving, consists in causing a luminous spot, or several spots, to describe an orbit corresponding to the desired pattern, and photographing the orbit. The negatives obtained are used for producing photomechanical printing- surfaces. The luminous spot or spots may be formed by openings 17 in an opaque screen 16 behind which is an illuminated translucent plate 15, all mounted in a casing 11. This casing is moved laterally on a rotating platform 10 by a rotated crank 13 and a slot in the casing 11. The movements are obtained from clock-work 6 with gearing 3, 9. The width of the lines of the pattern traced are varied by altering the size of the openings 17, and broken lines are obtained by intermittingly cutting off the light or periodically obscuring the luminous spot. Alternatively, the design may be produced by moving the lens or sensitive plate of the camera A. For producing stereoscopic effects and thereby increasing the safety of the note, arrangements may be made for photographing the luminous spots by stereoscopic lenses, and for imparting a second relative motion to them in the direction of the optical axis. The two stereoscopic images thereby formed will give a solid effect and may be printed in different colours.
