Title: Improvements in or relating to sheet-delivery mechanism of printing machines
IPC: B65H29/34
Filed: 1921-03-23
Abstract: 181,151. Linotype & Machinery, Ltd., Stern, C. L., and Bugler, A. V. March 23,1921. Delivery apparatus.-Relates to sheet-delivery mechanism for printing machines of the kind comprising a reciprocating carriage on to which a sheet is delivered by tapes during the outward travel of the carriage, and from which the sheet is swept on to the delivery board during the inward travel of the carriage by fingers projected between the bars of the carriage, these fingers being carried by a rock-shaft supported in brackets adjustably fixed to bars located at the side of the machine by means of ping insertable into holes in the brackets and holes along the side bars, and consists in obtaining a finer adjustment of the finger rockshaft by providing a plurality of holes in the brackets spaced apart by a distance differing from the intervals between the holes in the side bars. As shown, the fingers 7 are carried by a rock-shaft 8 supported above the path of the reciprocating carriage 3 by brackets 9, 10, adjustable along side bars 11, series of holes 29 being provided along the brackets closer together than the holes 30 in the side bars so that for almost every possible position of the brackets one of the holes 29 registers with one of the holes 30 in a manner resembling the graduations of a vernier scale. Pins 31 secure the brackets in position. The shaft 8 is rocked by means of an arm 12 provided, as already proposed, with a non-radial slot 13 engaged by a stud 14 on one arm 15 of a bell-crank lever, the other arm 16 of which is connected by a rod 18 to a cam lever 20 actuated by a roller 22 on the carriage to lower the fingers 7 into position between the bars 1 of the carriage ready to sweep off the sheet on to the delivery table 32. As the carriage approaches the limit of its inward travel, the roller 22 strikes against a curved lever 24 having a projection 25 bearing against the arm 15 of the bell-crank, thus raising the fingers 7 out of the way of the next sheet delivered from the tapes 4 on to the carriage.

Title: Improvements in and relating to the transmission and reception of ultra high frequency electromagnetic energy
IPC: H01J17/04
Filed: 1955-03-28
Abstract: 765,645. Waveguide switches. BRITISH THOMSON-HOUSTON CO., Ltd. (General Electric Co.). March 28, 1955, No. 9009/55. Class 40 (8). A transmit-receive switch for a pulse-echo system comprises means for rotating the plane of polarization of energy above a certain intensity level whilst not affecting the polarization of energy below this level. Verticallypolarized TE11 waves are propagated from a transmitter (not shown) along a circular waveguide. 10 in the direction indicated by the arrows. The energy level of these waves is sufficient to cause ionization of the gas within two hollow dielectric tubes 13, 14 which are arranged to lie along the inner surface of the guide in a helical surface which has a total angle of rotation of 90 degrees. The effect of the tubes is to rotate the plane of polarization of the transmitted energy which is thereupon radiated from an antenna as a horizontallypolarized wave. The echo (received by the same antenna) is also horizontally polarized but has insufficient energy to cause ionization within the tubes 13, 14 so that the waves pass unchanged along the waveguide 10. They are, however, prevented from entering the transmitter by a wire screen 16 having a configuration such that it forms a short-circuit for horizontally-polarized waves but does not affect the propagation of vertically-polarized waves. The screen 16 is positioned approximately onequarter wavelength away from a window 5 through which the horizontally-polarized waves are coupled into a rectangular guide 11 leading to a receiver. In theory there should be no radiation of the vertically-polarized transmitted energy into the rectangular guide 11. In practice, however, some radiation occurs and in order to prevent this reaching the receiver a low-power TR cell is formed between the window 5 and a further window 7 in the rectangular guide 11. In a modification of the rotating device (Fig. 2, not shown), a number of empty tubes of the same shape as the gasfilled tubes 13, 14 are arranged with the tubes 13, 14 to complete the symmetry of the device. In a further modification (Fig. 4), the rotating device comprises a number of short gas-filled dielectric tubes 33-37 lying at right-angles to the axis of the guide 10 in a helical surface.

Title: Improvements in or relating to colour-television image-reproducing apparatus
IPC: H01J29/56
Filed: 1953-04-07
Abstract: 729,685. Colour television tubes. PHILIPS ELECTRICAL INDUSTRIES, Ltd. April 7. 1953 [April 10, 1952], No. 9394/53. Class 39 (1), [Also in Group XL (b)] In a colour television system in which the receiving cathode-ray tube screen is comprised of a repeating series of red, green and blue strips scanned in the direction of the strips, the cathode-ray beam is arranged to exhibit astigmatism whereby, with a change in the tube focus, the spot on the tube screen may be arranged to change in shape as shown at 10, 11 and 12 in Fig. 2. With the spot as shown at 10 three colour strips are embraced and white is produced. With the spot as shown at 12 only one strip is covered and a fully saturated colour is produced. With intermediate shapes of spot, such as 11, varying degrees of saturation are produced. The system operates with signals conveying information of image brightness, degree of saturation and colour which are applied respectively to the tube modulator, focus coil and an auxiliary frame deflection coil employed to position the scan on the correct coloured strips. As an alternative, the colour signal may be combined with the sawtooth in the normal frame deflection coils. The astigmatism may be produced: (1) by energizing the line or frame deflection coils in parallel with deflection current and in series with direct current, Fig. 5 (not shown); (2) by a flattened or elliptical shaped coil energized with direct current and disposed around the tube between the focus coil and screen, Fig. 4 (not shown); (3) by an electron-optical system comprising a tubular electrode of elliptical section; or (4) by maintaining the mean potential of deflecting plates (when electrostatic deflection is employed) different from the voltage of the final anode. To prevent variations in the beam current causing variations in focus, a voltage derived from the brightness signal may be applied as a converting voltage to the focus coil.
