Title: Method of Stretch Forming a Hollow Thermoplastic Article at a Temperature below the Crystalline Melting Point thereof
Inventor: COFFMAN PAUL MAHONEY
IPC: B29C67/00
Filed: 1968-12-12
Abstract: 1,184,647. Deep drawing. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. 12 Dec., 1968 [14 Dec., 1967], No. 59155/68. Heading B5A. Hollow articles having a controlled uniform or non-uniform wall thickness are made by deep drawing a peripherally clamped billet using a male plunger, the portion of the billet engaged by the plunger being provided with a weakened region of less area than the contacting area of the plunger. This weakened region enables material more readily to flow from under the plunger into the side walls of the drawn article. The weakened region may be provided by a reduction in thickness by heating the region to a higher temperature, and thus plasticity, than the surrounding area or by providing a blank comprising an annulus of one material superimposed upon a disc of the same or a different material. The flow of material off the plunger may be enhanced by reducing the friction of the plunger by lubricants or by layers of, e.g. nylon. In the illustrated example a blank having a thin central portion is drawn by a plunger into a female die, over which it is clamped by a ring.

Title: Production of half tone facsimile separations with optional screen angles
IPC: H04N1/52
Filed: 1979-06-25
Abstract: A method for producing half-tone printing blocks having an optional screen angle and screen line spacing by line-wise scanning of an original and recording by means of a recording element displaced over a recording medium is described. The recording medium has co-ordinated with it an UV co-ordinate system directed in the line direction and and XY co-ordinate system turned through the screen angle, both co-ordinate systems being subdivided into areal elements from which the picture elements or half-tone dots to be produced are collated. Notwithstanding the screen angle  beta , screen threshold values are associated with the areal elements of a limited scanning pattern range which corresponds to at least one mesh element of the screen which is to be recorded, as a function of their XY locus co-ordinates. During the recording operation, the UV locus co-ordinates of the areal elements momentarily traversed by the recording element are registered on the recording medium, are recalculated in the form of the corresponding XY locus co-ordinates of the limited screen scanning range under consideration of the screen angle, and the screen threshold values associated with the XY locus co-ordinates determined are "called up". A control signal which determines whether the areal element in question is or is not recorded on the recording medium as part of a screen element, is generated for the recording element by current comparison of the screen threshold values called up with the image signal obtained by scanning an original. <IMAGE>
