Title: Method of making a printing plate from a porous substrate
IPC: B29C59/02
Filed: 1975-04-25
Abstract: 1502299 Printing plate LOGETRONICS Inc 25 April 1975 [2 July 1974] 17327/75 Heading G2C A printing plate is formed by bringing into contact with a blank plate of open cell thermoplastics material a layer of coating material which either absorbs or reflects radiant energy, causing the coating material to adhere to the plate in selected areas, removing the remaining coating material, and applying radiant energy to the coated plate, whereby the coated and uncoated areas are differentially heated with differential collapse of the open cell structure and formation of a relief image. The thermoplastics material may be of polypropylene or nylon. Heat-absorptive coating material may be a carbon/nitrocellulose mixture supported by a radiation transparent cover sheet, e.g. of polyethylene terephthalate (which is removed before the radiant heating). The selective adherence of the coating material may be effected during the application of vacuum or an electrostatic charge by scanning with a modulated laser beam or by impact (e.g. with a typewriter). The coated plate may be heated in an oven to just below its transition temperature before the radiant heating. Contrast may be increased by (a) passing the radiant energy through a filter in the form of an air-cooled rotary disc of the same material as the plate, (b) scanning with radiant energy using feedback to increase the intensity where the absorption is high and vice versa, or (c) carrying out the radiant energy heating in two steps, the coated plate being subjected to vacuum during the second step to draw cooling air through the non- collapsed areas.

Filed: 1926-07-12
Abstract: 268,610. Druppel, E., and Wery, G. July 12, 1926. Reaping - machines. - In apparatus for cutting papyrus and similar reeds, a cutter capable of being lowered beneath the water for the cutting operation is carried by a pivoted framework on a boat or moving vehicle provided with suitable means of propulsion, the cutter after severing the reeds being raised to perform a combing-like action on the reaped stalks which float astern and are gathered by gripping rolls into a conveyer, whence they pass either into the boat itself or to a separate lighter. As shown a bolt 1 carries, by means of arms 17 pivoted at 18, a cutter comprising a fixed comblike blade 23 with which co-operates a similarly shaped blade moved transversely across the fixed blade for the cutting operation by means of gearing in watertight casings 30. The gearing which comprises worm and bevel gearing is operated by flexible shafts 40 from gearing 41 operated by a motor and transmits motion to a spur wheel with interrupted teeth gearing through a second spur wheel with a rack on the movable blade carrier. This carrier is provided with rollers engaging tracks on the casing 20. At the ends of the traverse due to the interrupted gearing the movable blade of the cutter stops. In the automatic stop motion shown in Fig. 5, a shaft 46 driven by worm gearing 48, Fig. 1, from the motor shaft carries a pulley 44 loose and an arm 49 fixed on it. The arm carries a spring-pressed pivoted rod with projections 53, 56 the former engaging a stop 54 on the loose pulley 44 to rotate it until the latter is forced aside by engaging a roller 55. The rotation operates the cable 7 to raise the cutting mechanism, which drops again under its own weight when the pulley is freed, the fall being limited by a projection 57 meeting a spring stop 58. A hand-operated winch 8 may be employed to adjust the depth. A sheet iron casing 60 rendered buoyant by an air chamber serves for deflecting the cut reeds to the gathering apparatus shown in Fig. 8. The gathering apparatus may be attached to a lighter 70 following the boat and comprises an outwardly tapering buoyant member 71, a series of paddles 82 on a shaft 81. a series of pairs of spring-pressed rollers 74. and an inclines 87.
