Patent DE-3472919-D1 (DE)
Title: Method and apparatus for extruding a plastic pipe with controlled wall thickness
Inventor: BORGER JACOBUS BERNARDUS
IPC: B29C48/395
Filed: 1984-12-21
Granted: 1988-09-01
Abstract: A pipe of thermoplastic polymer, e.g. polyvinylchloride is extruded.The wall thickness of the pipe is controlled in order to obtain a pipe of a substantially even wall thickness. For said control the wall thickness of the extruded pipe is measured at 360 points equally distributed over the circumference and moreover the average is determined in eight measuring sectors comprising 45 measuring points per sector. The average of the measuring values of one measuring sector is compared with the circumferential average of the 360 points, the deviation of the desired wall thickness in said one sector being counter balanced by the action of the heating elements.The apparatus of the invention for executing the method of extrusion of a pipe of thermoplastic polymer comprises an extruder with an extrusion die 2 having a moulding end part 2a and heating elements 11, 11' located about said end part 2a, and a wall thickness measuring device 7 being rotatably about the circumference of the pipe. The wall thickness measuring device 7 is transmitting measurement data to a signal processing unit 9. A comparator element 10 is provided for comparing two values of measurement values averaging operations and said comparator element 10 acts upon the temperature control device 8 controlling the temperature of the heating element 11 in a temperature control sector located in the axial extension of a measuring sector as compared with the average of the total circumference of the pipe.

Inventor: HOLZ EMIL
IPC: D21F1/60
Filed: 1984-09-29
Granted: 1988-09-15
Abstract: The strips run at least approx. in the peripheral direction and are placed on edge in the radial direction. Straight and corrugated strip sections follow each other in the axial direction and the straight sections are connected to each other through the corrugated sections, whose outer radial edges feature recesses. The roll periphery is formed by a coating fabric, which rests at least on the corrugated strip sections. Between the fabric and the strips, on the connecting points in the area of the radial outer edges of the corrugated strip sections, the invention incorporates passages permitting a throughflow in the peripheral direction. The corrugated strip sections feature additional recesses on their radial outer edqes approx. in the middle between the connecting points. The covering fabric lies directly on at least the corrugated strip sections.

Title: A chair back with adjustable lumbar support
Inventor: RONNHULT JOHN
IPC: A47C7/46
Filed: 1984-07-23
Granted: 1988-11-10
Abstract: The vehicle seat back comprises a support part suspended in a frame with two long side components extending along the back and joined by union components which are maintained stretched.  To each side component corresponds a tension component connected to their two end parts. The tension component can expose the side pieces to so great a breaking strain that they bend outwards arc-fashion, with the centre part of the arc pointing forwards.  A sway support is thus formed when the tension unit is activated by a regulator which varies the extent of outward bending.

Abstract: Microstructured surfaces currently in use and the processes used to make them have one or more shortcomings. Some have wide variation in the size distribution or aspect ratio of the microstructure. This variation renders the properties of the microstructured surface difficult to specify, making the surface a poor candidate for optical uses such as absorption or reflectivity. Some microstructures are peculiar to specific substrates, many of which are subject to corrosion. Some microstructured surfaces are opaque to electromagnetic radiation. This limitation precludes their use with transparent media. This invention provides an article comprising a substrate bearing a microlayer which comprises uniformly oriented, crystalline, solid, organic microstructures and a method for preparing said article. The microstructures may be mono- or polycrystalline. In the preferred embodiment, the microstructures are of uniform shape and size. The articles can be prepared by (1) depositing a vapor of an organic compound as a thin, continuous film onto a substrate to provide a composite, and (2) annealing the composite in a vacuum sufficiently such that a physical change is induced in the orginal deposited film to form the microstructures. The microlayer can be overcoated with other materials to provide desired properties to the article. The articles of this invention are useful for many forms of light trapping, energy absorption, imaging, data transmission and storage, and gradient index applications.

Abstract: A multilayer electronic circuit comprising at least three electronic circuit layers electrically interconnected by means of at least one interposed connecting layer which is conductive only in the Z-axis. Desirably at least four circuit layers are provided in two circuit layer pairs. Each pair comprises an insulating layer having opposing surfaces and having a circuit pattern on each of the opposing surfaces of the insulating layer.

The thus formed pairs are connected to each other the connecting layer interposed between one such pattern frome each of said pairs. The connecting layer comprises an electrically insulating resin containing electrically conductive particles. The quantity of the particles is statistically selected so as to be sufficiently dispersed to prevent electrical conduction along the X and Y axes of the connecting layer and sufficiently concentrated and of a size to insure electrical contact through the Z-axis of the connecting layer between conductive portions of the circuit layers which are in contact with the connecting layer and directly opposite each other through the connecting layer. The invention further includes a method for making the multilayer electronic circuit.
