Title: Improvements in or relating to the photo-mechanical production of half-tone printingplates
IPC: B41M9/00
Filed: 1953-03-19
Abstract: 726,846. Local copying by scanning. HELL, R. March 19, 1953 [March 20, 1952], No. 7609/53. Drawings to Specification. Class 40 (3). A half-tone printing plate is produced by a cutting tool operating on a blank which is " scanned" in synchronism with a picture original, the tool being electro-mechanically controlled by pulses at the desired picture-point frequency which are modulated in time and amplitude, both the time modulation and the amplitude modulation corresponding to functions of the brightness values photo-electrically obtained from the original. The pulses are obtained by adding a saw-tooth waveform of the relatively high picture-point frequency to the amplified output from the photo-electric cell and passing the result through a threshold circuit (Fig. 2, not shown) such that the output comprises triangular pulses varying in amplitude and length (Fig. 4, not shown) according to the photo-electric control. The original picture and printing-plate may be respectively secured to cylinders rotated on a common shaft driven by a synchronous motor (Fig. 1, not shown), and the picture-point frequency may be automatically synchronized by deriving the saw-tooth waveform from the motor supply by frequency multiplication. The picture original is illuminated via an optical system including a very high frequency rotary shutter and the photoelectric current, after amplification, is rectified before combination with the saw-tooth waveform. By suitably shaping the leading and trailing edges of the pulses in relation to the shape of the engraving tool the latter is made to enter and leave the plate at the same rate and the elements cut out from the printing plate have a length equal to their width. This is said to produce much clearer engraving and avoid the appearance of a preferential direction in the dot-pattern. Since printing practice prefers plates in which the pattern is inclined to the edge of the picture the original picture and the printing plate may be mounted at an angle on their carrying cylinders (diagonal cutting), or the engraved points of each line may be " staggered " with respect to the points on the preceding line and parallel cutting employed. Examples of diagonal cut, using a wedge-shaped burin, and parallel cut, using a spoon-shaped burin, are given in Figs. 7 and 8, respectively (not shown). The former system is preferred as the point of the tool does not leave the plate for brightness above 50 per cent, and it is shown that the peaks of the pulses may be limited to the 50 per cent brightness value without any effect on the pattern produced.

Title: Improvements in or relating to Electric Motors.
Inventor: WAURICK GERHARD
IPC: H02P1/26
Filed: 1968-02-16
Abstract: 1,186,144. Control of A.C. motors. G. WAURICK. 16 Feb., 1968 [20 Feb., 1967], No. 7613/68. Heading H2J. An induction motor 2 is started by closing switch 9 so that the mid-points 8 of a delta capacitor network are connected to supply lines 4, the capacitors 5 being arranged in parallelpairs in each arm of the delta. After the main switch 10 has been closed, a large leading current is drawn by the parallel branch circuit 3 to compensate for the lagging current taken by the motor. The switch 9 is opened when the motor reaches full speed, so providing a pair of series-connected capacitors in each arm of the delta network. The magnitude of the leading current is now reduced to compensate for the smaller lagging current drawn by the motor. A relay is connected between the terminals of the motor and is associated with the switch 10 to prevent restarting while the motor is still selfexcited.

Abstract: 454,005. Projectile fuzes. BIRKIGT, M., Rue du Capitaine Guynemer, Bois-Colombes, Seine, France. March 13, 1936. No. 7615. Convention date, Jan. 18. [Class 9 (i)] Relates to fuzes, especially intended for small-calibre pro. jectiles fired from rifled guns, and comprising a firing-pin locked by balls surrounded by a wall having apertures equal in number and size to the balls, means being pro. vided for preventing access of the balls to the aperture until the shot is fired. Accord. ing to the invention, an annular closed rotating path concentric with the axis of the projectile is formed for the balls to rotate in until they have acquired the rotation of the projectile and gathered sufficient centrifugal force to escape through their respective apertures. In the form shown, a firing-pin 7, provided with a head 11 behind a closing disc 10, is formed with a shoulder 12 supported by the balls 13 resting in a concave annular conical seat at the end of a fixed thimble 14. The apertures for the ball 13 might be in a fixed wall and closed by a partition of paper or thin sheet easily torn by inertia or centrifugal force ; but in the preferred form shown, the apertures 15 are formed in a split sleeve 17 held by friction in the forward position until the shot is fired, when the sleeve sets back, bringing the apertures opposite the balls. These then escape in due time through the apertures and ride up a conical wall 19 to an enlarged groove 18, leaving the firing-pin free to operate.

Abstract: 1,089,711. Brushes for rolling mills. LOEWY ROBERTSON ENGINEERING CO. Ltd. Feb. 17, 1966 [Feb. 22, 1965], No. 7640/65. Heading A4K. A cylindrical drum (1) of a steel wire rotary brush 2, for cleaning the surface of a working roll in a rolling mill, is driven by an internal hydraulic motor (5) of the impeller type. The motor is rigidly mounted on the end of one stationary shaft (3) of the brush. Preferably, a relatively slow axial oscillation of the brush is simultaneously effected, by means of a planetary reduction gear 26, carried on a non- rotatable axially movable sleeve 23, keyed to the other stationary shaft 4. The rotation of the brush 2, on the bearings 24, is imparted to the input shaft 27 of gear 26, so that the output shaft 30 drives link 34 around its eccentric bearing 37. The varying inclination of the link produces oscillatory axial motion of the parts 30, 26, 27, 29, 23, 25 (1) and 2.
