Title: Improvements in or relating to rotary printing machines
IPC: B41F13/02
Filed: 1945-07-20
Abstract: 598,118. Feeding webs. JONES, K. W. July 20, 1945, No. 18629. [Class 100 (i)] In a web-fed rotary printing machine comprising one or more printing-units each comprising a stereo cylinder 1 and an impression roller 2, and means for maintaining tension on a web 3 as it passes through the units, a suction roller 7 either following or preceding the couple is provided constituting a master control cylinder effective to coordinate the draw of the web with the requirement of the cylinder 1 and maintain accurate register, the roller 7 being driven from the cylinder 1 or roller 2 by gearing co-related with the respective diameters to maintain constant the predetermined relation of the peripheral speeds of the roller 7 and the cylinder 1. The use of a suction roller is said to preclude slip between the web and the roller, any variation in the feed of the web due to variations in the diameter of the stereos being adjusted when gaps between the plates release the web. The roller 7 may be a perforated roller, e.g., as described in Specifications 559,388 and 570,795, or a non-perforated roller in a suction box 9 as described in Specification 598,148. By means of an intermediate gear 8, the roller 7 is driven from the roller 2 at a speed which may allow for known stretch of the web in travelling from the couple 1, 2 to the roller 7. Tension on the web is maintained by a brake on a supply roller 4 or by a suction bar or a suction roller 11 having a peripheral speed less than that of the couple 1, 2, the suction being such that the web can slip. Where the roller 7 precedes the couple, a roller 11 driven faster than the couple follows the latter, the suction allowing slip. A two-colour machine is described, the couples being connected by a gear between the impression rollers. Each couple of a multi-colour machine may have its own rollers 7 and 11.

[Class 39 (i)] A cathode-ray tube is provided with an electron-optical system comprising first and second lens systems having an apertured diaphragm therebetween, the first lens system being so adjusted that in the absence of the second system a maximum constriction of the cathode ray beam would occur in the region in which are positioned the second lens system and the deflecting elements, and the second lens system being so adjusted that there is produced on the image screen of the tube a reproduction of the aperture in the diaphragm. The cathode 2 of the tube is provided with a Wehnelt cylinder 4 having a diaphragm 4<1> and provided with a rim 4<11> of a width of the order of the radius of the cylinder 4, and serving to produce a weak preliminary concentration of the beam, the rays of which are thus rendered approximately parallel. The electrons are accelerated by a first anode 5, and the voltage applied to a cylindrical member 6 forming the first lens is adjusted to give a narrow beam in the neighbourhood of the main anode 9 and the deflecting plates 10, 12. A cylindrical member 8 which screens the beam between the parts 6, 9 from interfering fields is provided with a diaphragm at its end remote from the cathode and cooperates with the anode 9 to form the second lens by means of which an aperture in a diaphragm 7 is reproduced on the screen. The diaphragm 7 may be operated at a potential between that of the anodes 5, 9 or may be connected directly with the anode 9. The potentials of the cylinders 6, 8 may be positive or negative relatively to the cathode ray traversing them and relatively to the apertured diaphragms 5, 7. The distance between a pair of deflecting plates is preferably somewhat larger than twice the diameter of the ray in that region and the deflecting potentials applied to the plates are in reverse phase. Dimension and operating potentials are given in the Specification. Specifications 440,087, 452,650, 456,717, and 470,496 are referred to.

Title: Turning or tilting device for rolled products
IPC: B21B39/24
Filed: 1972-04-24
Abstract: 1382088 Rolling mill manipulator MOELLER & NEUMANN GmbH 24 April 1972 [24 April 1971] 18891/72 Heading B3M  A manipulator for turning over elongated rolled products comprises a pair of rollers 1, 2 supported on holders 4 and 6, the holders being carried on a guide 8 which is rotatable about a transverse axis (to tilt the rollers) and which is simultaneously movable vertically. The guide 8 is supported in a rockable casing 9 which, is supported by trunnions 12 and 14, Fig. 2, in a frame 16, the guide being rotatable about the axis of the trunnions by a rock 18. The guide has an inverted U-shaped section, Fig. 2, which encloses hydraulic cylinders 10 and 11 for moving the holders (and hence the rollers) towards and away from each other. To generate vertical movement of the rollers as they are tilted about the trunnion axes, the frame 16 is supported by wheels 26 and 28 on fixed rails 29. The wheels are coupled to the housing by pivoted arms 22 and 24, the arms being linked together by cranks 36, 38 and a link 40 for rotation in unison. The arm 24 is coupled by a normally fixed-length hydraulic ram 32 to the casing 9. When the casing 9 is tilted in an anticlockwise sense by the rack 18, the upper end of ram 32 follows the path 35 to the point 34<SP>1</SP>, and the pivots of the arms move to points 20<SP>1</SP> and 21<SP>1</SP>. The whole assembly is thereby raised. By releasing the ram 32, the assembly falls under its own weight, and the rollers 1, 2 drop below the level of a roller table. 42.

Title: Improvements in radio receiving systems
IPC: H03D11/02
Filed: 1924-08-09
Abstract: 229,938. Cachemaille, A. S., (Westing- house Electric & Manufacturing Co.). Aug. 9, 1924. Thermionic heterodyne receivers.-Damped signals are received by a process which consists first in applying a local heterodyne frequency which converts the incoming energy into a modulated high-frequency wave. This is then applied to a super-regenerative receiver of the type described in Specification 182,135. The aerial 2, 3, 11 is tuned to the damped spark signal frequency corresponding to a wave-length of say 360 metres. Local oscillations frcm a generator 9 are fed into the aerial so as to give a rectified beat frequency corresponding to a wave-length of say 3,000 metres, which is in effect an undamped wave modulated by the damped and spark signals. This intermediate frequency is applied through a transformer 14 to the superregenerative receiver 21, the detected and amplifield signal component being then passed through a final amplifying stage 31 to the phones 32. Owing to the fact that the aerial is tuned to a frequency very different from that of either the heterodyne or super-regenerator circuits, oscillations occurring in the latter cricuits are effectively prevented from energizing the aerial and so causing local interference.
