Title: A method of and a plant for the manufacture of corrugated building sheets
IPC: B28B1/52
Filed: 1967-02-16
Abstract: In a corrugating machine (see heading B5A), a pair of lifting devices 18 and 17, actuated by hydraulic cylinders 100 and 101, are carried by a cylinder 70 which is reciprocable over a horizontally disposed fixed piston 71. The cylinder is provided with brake chambers 81 and 82 each of which communicates, via throttle valves 85 and 86, with the chambers 76, 77 respectively (77 not marked) located either side of the piston. The brake chambers are connected to the cylinders 100 and 101 via non-return valves 95 and 96 and the chambers 76 and 77 via braking valves 85 and 86. In operation, the cylinder is moved to the left by introducing fluid into chamber 76 via hollow piston rod 74 and apertures 72, this movement being braked when the apertures 73 become located in brake chamber 82 and the exhaust fluid has to pass from chamber 77 via throttle valve 84 to the piston rod 75 and thus out of the system. When the end point has been reached, the fluid supplied to chamber 76 flows through valve 93 and actuates the cylinders 100 and 101, the exhaust from the cylinders passing through conduit 99 valve 96 and conduit 90 to the brake chamber 82 and thus out of the system. The reverse movement of the cylinder is initiated by introducing fluid into chamber 82 and exhausting it from 76. The fluid initially passes from chamber 82 around conduit 90 and through valve 92 to chamber 77 and then passes directly to chamber 77 when aperture 73 are clear of chamber 82.

Title: Shaped articles from insoluble hydrogels and method of manufacturing same
IPC: C08F6/00
Filed: 1970-06-06
Abstract: Substantially water-insoluble, water-swellable crosslinked hydrogels are prepared by polymerizing monomeric material consisting predominantly of acrylonitrile in aqueous salt solution containing zinc chloride as the main component, in absence of added crosslinking agents. The concentration of acrylonitrile is in the range of about 20 to about 40% by weight, related to the weight of the polymerization batch as a whole 100%. The process is carried out by partially hydrolyzing the primary gel thus obtained which consists of polyacrylonitrile plasticized with the aqueous salt solution, whereafter the zinc ions are removed from the gel by treating it with a dilute aqueous solution of at least one electrolyte forming an insoluble precipitate therewith. The partial hydrolysis may be carried out either by increasing the acidity of the solution or temperature or both. Insoluble crosslinked hydrogels are prepared in the form of shaped articles, preferably in either closed or open molds, or in raw castings such as sheets or plates from which the final shaped articles can be manufactured by mechanical processes such as by cutting.

Title: In-line electron gun
IPC: H01J29/48
Filed: 1973-01-05
Abstract: The three co-planar beams of an in-line gun are converged near the screen of a cathode ray tube by means of two plate-like grids transverse to the beam paths and having corresponding apertures for the three beams. The three beam apertures of the first grid are aligned with the three beam paths. The two outer beam apertures of the second grid are offset outwardly relative to the beam paths to produce the desired convergence. The three sets of apertures also provide separate focusing fields for the three beams. The second plate-like grid is formed with a barrel shape, concave toward the first grid, to minimize elliptical distortion of beam spots on the screen due to crowding of the adjacent focusing fields. Each of the two outer beams is partially shielded from the magnetic flux of the deflecting yoke by means of a magnetic ring surrounding the beam path in the deflection zone, to equalize the size of the rasters scanned on the screen by the middle and outer beams. Other magnetic pieces are positioned on opposite sides of the path of the middle beam, to enhance one deflection field while reducing the transverse deflection field for that beam.
