Title: Improvements in or relating to processes for producing photomechanical printing plates
IPC: G03F7/04
Filed: 1925-06-09
Abstract: 236,532. Sachsisches Serumwerk Akt.-Ges., and Galetzka, A. July 1, 1924, [Convention date]. Photo-mechanical printing-surfaces.-In preparing printing-surfaces which may be used for letter-press or screen pictures or both combined, a sensitive layer which is exposed and treated to form the printing surface is coated on an elastic ink-repellant non-sensitive layer, and the parts of the printing surface not functioning for ink or colour transfer are removed, exposing thereat the ink-repelling layer. The base may be of any character (e.g. metal, glass, cellon or stone), and is preferably first coated with a thin coating of gelatin, waterglass and chrome alum. The intermediate ink-repelling layer is preferably water-absorbent, and conveniently of gelatin which is just sufficiently hardened to prevent any absorption of moisture during the short drying period after sensitizing, but allowing absorption of water during the subsequent developing in cold water. The water during development penetrates through the unexposed parts of the sensitive layer and swells the intermediate gelatin layer, raising the exposed parts evenly, and the layer forms a resilient backing behind the printing layer. A very thin sensitive layer may be used, in which case a substantially flat printing surface is obtained, or the sensitive layer may be thicker in which case a letter-press type of printing surface is produced.

[Class 12 (iii)] A lubricating system comprises a main constant-pressure pump 12, shown as a vane pump, delivering through a metering pump 19, which is short-circuited for priming when starting up, the short circuit being closed automatically after a predetermined time lag. The pump 19 is short-circuited by a priming valve 25 having a piston moved by oil from a servovalve 31 connected to metering pump 19a, the rate of delivery from pump 19a determining the time lag. When the servo-piston 32 is depressed, oil from pump 12 flows by pipes 29, 35, 36 and the waisted portion 34 of piston-32 to the piston of valve 25.

Abstract: 1341744 Corrugating REICHE & CO 17 May 1971 [5 June 1970] 15331/71 Headings B3E and B3Q Apparatus for corrugating a tube 1, Fig. 1, comprises a plurality of tool rings each having a plurality of shaping tools 5 movable radially to cause their working faces to form corrugations in the tube wall, and a member having a control face 10 which moves the shaping tools of the tool rings radially upon a relative axial movement between the control face and the tools, the configuration of the control face and the construction of the tools being such that zones of varying yield strength to longitudinal compression loads can be formed along the length of the tube, zones of high yield strength being formed by moving the tools of at least two rings simultaneously by the control face, with the shaping tools of one tool ring leading. The simultaneous movement of two rings to cause a localized thinning of the tube wall is effected by making the axial length a, Fig. 3, of the control face larger than the thickness of the parts of tools 16-19 adjacent the control face. The thickness b of tools 21 and 22 equals the length a so causing only one ring at a time to be moved which results in the thickness of the tube wall remaining constant. Return movement of the tools is effected by the movement of a bar 13 in the direction of arrow 15 so that elbow 14 in the bar engages faces of the tools within apertures 12. In another embodiment, Fig. 4, the simultaneous movement of two rings is effected by having recesses 24 between the tools 26 such that the width c of the recesses is less than the stroke h provided by the control face. Movement of the rings one at a time is effected by making the width d of recesses 25 equal to the stroke h. In another embodiment (Fig. 5, not shown) a pressure ring has two control faces having different axial lengths, each face engaging a different surface in the rings.
