Patent DE-3377779-D1 (DE)
Title: Laminating method and apparatus for manufacture of reinforced film
Inventor: OSBORN PAUL VICTOR
IPC: D04H3/04
Filed: 1983-02-09
Granted: 1988-09-29
Abstract: A fibre-reinforced composite film sheet is produced having fibres lying in both machine and transverse directions sandwiched between a pair of sheets. A warp of machine direction fibres is produced by converging and aligning fibres from supply bobbins. The warp is overlaid with a planar lap of transverse fibre produced by passing a single fibre from a supply bobbin continuously between a pair of horizontally diverging chain assemblies, equipped with rotating spindles about  which the fibre is stretched and makes 180 deg. loops. A tubular film is drawn from a supply and cut into a pair of sheets by edge cutters. The sheets are sepd., turned through 90 deg. by turning bars above and below the fibre plane, laterally expanded by expander rolls and brought into contact with the fibre to form a sandwich at a convergence assembly, the edges, inwards of the transverse fibre loops being immediately heat sealed. The loops are then removed from the spindles by a cam operated loop pick-up assembly, the laminate is smoothed and flattened, and entirely bonded by passage between heated rollers. It is then wound up. The film is a coextrusion of high density and low density polyethulene, the low density polyethylene being disposed adjacent the fibres and comprising 25 wt.% of the film. The fibres can be monofilaments or polypropylene tapes. A flexible reinforced plastic sheet material is produced having lower basis wt. and higher strength than previously existing materials. The composite sheet is partic. suitable for producing high volume sacks for bulk materials. The composite can be produced at faster prodn. rates.

Abstract: The present invention provides translation circuitry, which in one mode of operation acts to encode variable length data words into fixed rate data coded words for use with a communication channel, or a recording means, such as a magnetic recording medium and which in another mode of operation acts to decode the coded words to data words. The translation circuitry functions such that in an encoding operation, the second and third bits of a three-bit coded word, respectively, have the same binary values as the first and second bits of the data word, which the coded word represents and the second and sixth bits of a six-bit coded word, respectively, have the same binary values as the third and fourth bits of the data word which the coded word represents.

Title: Device with a variable impedance filter for the treatment of hydrocephalus
Inventor: SAINTE ROSE CHRISTIAN
IPC: A61M1/00
Filed: 1984-01-05
Granted: 1988-10-13
Abstract: To treat hydrocephaly, an intracranial catheter is implanted in the head. It is connected to a tube fitted with a non-return valve and serves to divert the flow of cephalo-rachidian liquid to the peritoneum or to the right auricle of the heart. In accordance with the invention a hydraulic filter of non-linear variable impedance is connected in the tube in series with the valve. The filter maintains an average flow rate of the cephalo-rachidian liquid close to the physiological flow rate, but prevents sudden rushes of fluid flow, thereby permitting the intracranial pressure to vary in the short term in the normal manner over a characteristic period of about one second, while preventing said pressure from rising slowly in the long term, e.g. over a characteristic period of about one minute. This is done by a bead (160) which is housed in a cavity (161) extending between a proximal orifice (111) and a distal orifice (136). The distal orifice constitutes a leaky valve seat for the bead.

Abstract: A coherent bond is formed for thin metallic sheets by hot press welding an auxiliary deformable material to the sheets to be bonded together. During application of a force to the deformable material, the oxide layer on the metallic structural elements is physically moved by the deformation of the auxiliary deformable material. In this manner, the auxiliary deformable material is directly bonded to clean metal and is built into the crystalline lattice structure of the thin metallic elements to thereby produce a coherent bond.

Abstract: The density of the energy that is conducted within a fiber-optic waveguide is increased by means of an energy coupler at the input end of the optical fiber. This energy coupler comprises a fused or ground lens at the input end of a silica-based fiber. A second lens, preferably a plano-convex lens, focusses a large collimated laser beam to a point source. The lens at the end of the fiber is located at a distance greater than the focal length of the second lens, so as to receive light from the point source and couple it into the fiber.

Abstract: A magnetic field enhanced single wafer plasma etch reactor (60) is disclosed. The features of the reactor include an electrically-controlled stepped magnetic field for providing high rate uniform etching at high pressures; temperature controlled reactor surfaces including heated anode surfaces (walls and gas manifold) and a cooled wafer supporting pedestal/cathode (70,72); and a unitary wafer exchange mechanism (74) comprising wafer lift pins (79) which extend through the pedestal and a wafer clamp ring (78). The lift pins and clamp ring are moved vertically by a one-axis lift mechanism (140) to accept the wafer from a co-operating external robot blade (76), clamp the wafer to the pedestal and return the wafer to the blade. The electrode cooling combines water cooling for the body of the electrode (70) and a thermal conductivity-enhancing gas interface between the wafer and electrode for keeping the wafer surface cooled despite the high power densities applied to the electrode. A gas feed-through device (114, 175, 176) applies the cooling gas to the RF powered electrode (72) without breakdown of the gas. Protective coatings/layers (81,83) of materials such as quartz are provided for surfaces such as the clamp ring and gas manifold. The combination of these features provides a wide pressure regime, high etch rate, high throughput single wafer etcher wich provides uniformity, directionality and selectivity at high gas pressure, operates cleanly and incorporates in-situ self-cleaning capability. <IMAGE>
