Title: Character input and display apparatus for a printing device
IPC: G06F17/24
Filed: 1965-12-17
Abstract: 1,085,859. Photographic type-composing. OLYMPIA WERKE A.G. Dec. 17, 1965 [Dec. 24, 1964], No. 53624/65. Heading B6W. Characters selected from a keyboard 2 are transferred from a permanent character store 3 to a working store 4, the contents of which appear visibly on a screen 5, while a separate record is made on a cassette in a text store 6. A visible mark also appears on the screen following the text under control of horizontal and vertical counters 8, 10. After each line, an end-of-line key in a function keyboard 1 is pressed, the last line is transferred to an intermediate store 11. justified by a margin alignment device 12 and returned to the working store. For corrections, the visible mark is moved by keys controlling the counters 8, 10 to the character or line to be erased, and a character, line or complete text is erased by one of three erase keys in the keyboard 1, the erasure being determined by the position of the visible mark. The corrected text on the screen 5 is photographed with or without the interposition of an optical system to produce printed copies 16. Alternatively, the cassette can be removed and used in a copying-apparatus. A numerator 14 is stepped each time a correction is made to indicate on the screen image the number of the last correction.

Title: Printing units
IPC: H01F7/16
Filed: 1969-11-03
Abstract: 1,220,769. Selective printing. PHILIPS ELECTROLOGICA G.m.b.H. 3 Nov., 1969 [2 Nov., 1968], No. 53704/69. Heading B6F. [Also in Division H1] A selective printer having an array of printing needles is characterized in that magnetic drive means for each needle comprises two magnets, one magnet arranged to move its respective needle against the force of a spring into a non- operational position, the other magnet arranged to move the same needle with the force of the spring into an operational position to effect printing. The moving type carrier of the printer comprises a holding plate (14, Fig. 1) mounted on a carriage 1 for the magnetic drive means 2 and a needle guide head 24 resiliently mounted to the carriage 1 by a pair of leaf springs 23 to allow for a degree of relative movement between the holding plate (14) and the needle guide head 24. The holding plate and the guide head are arranged to be driven along the printing line by separate but synchronous drives comprising band 44 and 25 respectively. This drive system allows the needle guide head to be stopped very accurately and independently of the large inertia of the holding plate (14) carrying the magnetic drive means. Wear of the printing needles is compensated for by moving the holding plate (14) relative to the carriage 1 against the force of a spring 22 with the aid of a cam 19 on a shaft 18 rotated by a knurled knob 20. Electromagnets.-Each electromagnetic drive means (Fig. 3) comprises a housing (34) containing two axially spaced solenoid coils (35a, 35b), yoke parts (36a, 37a) and (36b, 37b) and core parts (38a and 38b). The yoke parts extend into the coils and thus each magnet core is movable only within the space between the two yoke parts. A small diameter brass tube (39) is passed through both solenoid coils and the printing needle 33 is fixed in the tube. The cores (38a and 38b) are fixed to the tube. The cores are cone-shaped, the apices pointing in opposite directions. The tube (39) is mounted in a disc (40) and is fastened at one end to a spring (41). The spring (41) is firmly clamped between the yoke part (36b) and a ring (56).

Abstract: 1,198,878. Cross-linked olefin-vinyl ester copolymers. LEUNA-WERKE " WALTER ULBRICHT " VEB. 18 Nov., 1968, No. 54612/68. Headings C3C, C3P. Copolymers of an olefin and a vinyl ester are cross-linked by mixing and heating at 60- 250‹ C. with a cross-linking agent which has the formula Me(OR)x, wherein Me denotes a metal of valency x, which is 2-5, and R is an aliphatic or cycloaliphatic group. Suitable crosslinking agents are methylates, ethylates, propylates or butylates of beryllium, magnesium, calcium, zinc, titanium, zirconium, tin, antimony or iron. Higher alcoholates, such as stearylates, palmitylates or cyclohexyl alcoholates, may be used and the esters formed in such cases may be left in the cross-linked copolymer to function as a softener. The cross-linking agent may be added as a master batch i.e. in the form of a mixture of the copolymer with surplus alcoholate, or as a mixture of the alcoholate with a material inert respect to the alcoholate i.e. an olefin homopolymer. In the examples, (1) polyethylene and a copolymer of ethylene and vinyl acetate are blended arid heated with aluminium isopropylate; (2) as (1) except that dicumyl peroxide is added prior to or simultaneously with the alcoholate to permit selective cross-linking of the polymer; (3) a copolymer of vinyl acetate and ethylene are blended and heated with aluminium tripolmitylate, aluminium ethylate, titanium propylate, methanolic magnesium methylate, aluminium isopropylate (the evolution of isopropyl acetate foams the copolymer) or titanium octylate (in the presence of glass fibres); (4) a master batch of polyethylene and aluminium isopropylate is prepared, and is added to a copolymer of vinyl acetate and ethylene, with heating, whereupon isopropyl acetate escapes as a vapour and causes foaming of the copolymer; and (5) as (4) except that the master batch is prepared by reacting a copolymer of vinyl acetate and ethylene with aluminium isopropylate. The cross-linked copolymer, containing glass fibre filler is formed into slabs of high stability.

Title: Frequency Stabilization of Tunable Lasers
IPC: H01S3/08
Filed: 1967-12-04
Abstract: 1,180,139. Lasers. LOCKHEED AIRCRAFT CORP. 4 Dec., 1967 [28 Dec., 1966], No. 55146/67. Heading H1C. [Also in Division G1] In order to tune a laser which generates an output signal having two opposite circularly polarized axial modes of oscillation the two modes of oscillation are detected and their intensity magnitudes compared to obtain an error signal from which a control signal is derived which is used to alter the separation of the mirrors of the laser optical cavity. A xenon/ helium or neon/helium gas mixture is positioned in tube 14 with a pair of partially transmitting mirrors 16, 18, one of which, 16, is mounted on a piezoelectric element 22. If the mixture includes xenon the laser operates at the 2.65 micron atomic transition which is split to give two axial modes of oscillations V n , V n+1 , Fig. 2, by passing a current through coil 20 to produce an axial magnetic field. By suitably choosing the axial magnetic field a difference in intensity of the two oscillations V n  and V n+1  is produced which oscillations 32, 38 are oppositely circularly polarized and have a frequency separation different to that of the cavity resonances. The two modes of oscillation pass through mirrors 16, 18 to quarter-wave plates 26, 28 and then to analysers 30, 36 which pass vertical 38 and horizontally polarized 32 light, respectively. The two waves 32, 38 representing the V n  and V n+1  frequencies pass to photo-detectors 34, 40 which produce signals indicative of the intensities of the oscillations V n  and V n+1 . In the Figures the lower frequency V n  has the greatest intensity since the distance B from the centre of the atomic transition is greater than that of V n+1  so that the signal from photodetector 34 is greater than that from 40. The two signals are differenced in circuit 42 to produce an error signal which is fed to summing circuit where it is combined with a preselected value of D.C. bias from variable D.C. source 58 to produce a signal which is amplified at 52 and then fed to piezo-electric element 22. Mirror 16 is thus moved towards or away from mirror 18 to change the length L of the cavity and thus the frequency of oscillation, the spacing between the oscillating mode frequencies remaining fixed. The D.C. bias could be replaced by devices in lines 44, 46 which vary the magnitude of the signals from the photo-detectors for fine tuning. Integrators may be placed in the feed-back circuits to eliminate steady state frequency error. Both oscillating signals may be taken out through either 16 or 18 and then separated.
