Patent EP-0432423-A1 (EP)
Inventor: FEISTKORN WERNER DR DIPL-ING
IPC: B29C48/92
Filed: 1990-10-25
Abstract: For the axial, preferably biaxial stretching of tubular films laid flat after their production on a blown film extruder line, the said films are inflated again to form a tubular film bubble (4) or are expanded to form a film tube. In the inflated or expanded state, these then run through an oven (11), from which they are drawn off, with renewed flattening (12), at a rate which is increased with respect to the running-in rate by an amount corresponding to the desired stretching ratio. In order to ensure that the stretched tubular films have a substantially equal thickness distribution over their circumference, the film thickness of the stretched tubular film emerging from the oven (11) is measured over its circumference before or after its flattening (12) and the thickness distribution over the circumferential profile of the tubular film produced on the blown film extruder line is set according to the measured thicknesses of the circumferential profile in such a way as to compensate substantially for deviations from the average film thickness brought about in the oven during stretching on account of uneven heating and possibly other disturbing influences.

Abstract: A method for hydroentangling nonwoven fibrous sheet material to significantly increase the strength thereof at low latex add-on values employs small diameter jets of high-pressure water in the form of coherent streams that concentrate the hydraulic energy over a distance equal to approximately the diameter of the fibers being entangled. While fiber entangling water jets have been utilized heretofore, the present invention employs a relatively lower pressure for the fiber rearrangement along with a synergistic effect of wood pulp and long polyester fibers coupled with small amounts of latex to achieve the unexpectedly high strengths within these light weight materials. The resultant sheet material possesses excellent uniformity of fiber distribution and improved strength characteristics over those typically obtained from prior art water jet entanglement processes requiring 300-2000% the entanglement input energy employed in this process.

Abstract: This invention relates to an involute interpolation speed control system for making involute interpolation by applying tool correction for machining in a numerical controller or the like. The system instructs a rotating direction of a first involute curve (In1) as an actual machining shape, the coordinates (Pee) of an end point, the center position of a basic circle (C) as viewed from a start point (Pss), the radius (R) of the basic circle (C), a feed speed, a tool diameter offset direction and the radius of the tool (Rofs). An offset vector of the tool is generated from this instruction and an equation of a second involute curve (In2) connecting its start point (Ps) and its end point (Pe) is calculated. The radius of curvature of the second involute curve (In2) is determined and a feed speed override value is determined from the tool offset direction and the radius of curvature. The second involute curve (In2) is interpolated by the speed as the product of the feed speed and the feed speed override value. This interpolation is made so that the cutting speed (Fp) in the tangential direction of the outer periphery of the tool generating the actual machining shape becomes constant.

Abstract: Families of antagonist-agonists and opiate narcotics are produced from norhydrocodeinone. In a preferred embodiment, norhydrocodeinone is refluxed with sulfosalicyclic dimethylketal and delta-6-enol ether derivatives and is then converted entirely to the ether by the addition of dry tetrahydrofuran simultaneously with the removal of the thus produced ether. The ether is then reacted with methanesulfonic acid and N-bromoacetamide to form the hydrobromide salt of the 7-bromodimethylketal derivative. From this derivative, a variety of products can be derived, including the novel further intermediate 14 hydroxynorcodeinone. The present invention enables derivation using a starting material which, unlike the starting materials of prior art processes, is available in the natural (-) or synthetic (+) form. Thus, the method of the present invention provides the only known route for the synthesis of (+) forms of various derivatives and intermediates, such as (+)-7-bromo-dimethylketal nordihydrocodeinone.

Abstract: The invention relates to an electrical connector (20) for telecommunications, consisting of a flexible electrical lead (21) which contains a plurality of conductive cores (22) and consists of connecting elements (24, 30) at the ends (23, 25) of the lead. It is intended to make contact with the second connecting element (30) in an initial socket (10) which has a retaining body for making contact with a flat cable (11) without stripping the insulation. The retaining body (16) has a flat-cable cross-section with a retaining space matched to the flat cable and can move linearly up with respect to the contact blades of penetrating contacts which are positioned in the initial socket. In order to simplify the production and assembly of the electrical connector, it is proposed to provide an insert (30) consisting of insulation material for the retaining body (16) instead of the second connecting element at the end (25) of the lead, the insert (30) having an external profile which is matched to the flat-cable cross-section and, in the interior of the insert, has a hollow profile consisting of a plurality of parallel holes. The holes are arranged in the grid of the contact blades of the penetrating contacts in the initial socket, and the hole width is matched to the core cross-section of the flexible lead (21). The cores (22) of the lead (21) are inserted into these holes. <IMAGE>
