Title: Laser oscillator
IPC: H01S3/0975
Filed: 1988-04-28
Granted: 1993-03-24
Abstract: A laser oscillator which establishes r-f discharge by applying an r-f voltage to a plurality of discharge regions via a dielectric member in order to realize laser oscillation. The laser oscillator consists of a DC power source (16) and r-f power sources (18, 19, 20, 21) that convert a DC voltage into an r-f voltage. The DC power source (16) and the r-f power sources (18, 19, 20, 21) are coupled together via a filter (30). The filter (30) prevents r-f components from being fed back from the r-f power sources (18, 19, 20, 21), thus keeping the laser oscillator from unstable operation due to parasitic oscillation. Means is further provided to prevent interference between the r-f power sources and the DC power source.

Abstract: A sheathing material is disclosed for superconducting wires deformed by stretching or a similar process during their manufacture, and of which the superconducting material is composed of an oxide the superconductivity of which deteriorates following their deformation, necessitating recovery by annealing at temperatures above 940° in order to restore and further improve the original superconductivity. The sheathing material generally used for such wires is silver. Recovery by annealing is generally carried out at about 900°C. Research has shown that the optional temperature range for recovery by annealing lies between 940° and 1030°C approximately. These temperatures are higher, however, than the melting temperature of silver in an oxygen-containing atmosphere. The purpose of the invention is to provide a sheathing material having the same advantageous properties as silver, but which melts only at a temperature above the optimal temperature for recovery by annealing. A silver alloy having a melting temperature higher than the melting temperature of pure silver is proposed as sheathing material.

Title: Process and device for regulating the air feed in an internal combustion engine, in particular during idling and coasting
IPC: F02D41/16
Filed: 1988-11-23
Granted: 1991-04-03
Abstract: A process and a device are useful for metering the air during idling and coasting in an internal combustion engine. During idling, a PI regulator (203, 204) regulates the internal combustion engine on the basis of a set engine speed. At the same time, the volume of air (60) required is measured and stored in a memory (304). During coasting, the air flow rate is regulated on the basis of this stored value. In addition, a series of auxiliary values is used for the regulation, which facilitates regulation in each mode of operation.

Abstract: The invention provides for detection of changes in a nucleotide sequence based on the determination of the nucleotide sequence over the region of interest. The first step of the process involves obtaining an amplified DNA sample in which at least one attachment moiety has been introduced into at least one strand of a target polynucleotide by a modified polymerase chain reaction. This can be accomplished by synthesizing DNA using the target nucleic acid polymer as a template and using at least one amplification primer, which includes an attachment moiety bonded to the oligonucleotide. The resulting amplification mixture is repeatedly cycled between a polymerization condition and a denaturation condition occurs for a number of cycles sufficient to produce copies of the target nucleic acid polymer in a quantity suitable for use in a DNA sequencing procedure to form an amplified sample comprising copies of the target nucleic acid sequence bonded to the attachment moiety. After amplification, the strands of target nucleic acid polymer carrying an attachment moiety are captured using a solid matrix coated with an attachment site to which the attachment moiety or a modification thereof can bind. In this way, the strands of target nucleic acid become bound to the solid matrix and can be readily separated with the solid matrix from unbound reactants for sequencing.

Abstract: In a softpack-type cigarette packet, a pile of cigarettes is forced into a rectangular parallelepipedal wrapper (15) consisting of a composite foil cut-out whose edges overlap to form envelope folds and are bonded together by heat sealing. For ease of opening, an essentially U-shaped line of weakness (16, 16', 26) is provided in the wrapper material. Said line bounds a region of the wrapper in the vicinity or on the edge of the opening face (18) of the wrapper and is located on the surface of the smaller lateral face (17) of the wrapper parallel to the longitudinal direction of the cigarettes. A preferably self-adhesive opening tab (19, 23-25, 28), permanently bonded to the wrapper (15), is located inside the region bounded by the line of weakness (16, 16', 26). To open the packet, the edge of the opening tab (19, 23-25, 28) is pulled, thereby rupturing the line of weakness (16, 16', 26). The packet can be temporarily reclosed by replacing the opening tab (19, 23-25, 28) in its original position. A thinner wrapper material can be used, if it consists of a composite film (31) comprising two layers (16, 16', 26) connected to the larger lateral faces (34) of the wrapper only along the lines of weakness (16, 16', 26).

Title: Hydrostatische hilfskraftlenkung
Inventor: FASSBENDER ROLF
IPC: B62D5/06
Filed: 1990-11-07
Granted: 1994-08-31
Abstract: In hydrostatischen Hilfskraftlenkungen treten Synchronisationsfehler zwischen einer Drehbewegung am Lenkhandrad und der Bewegung der gelenkten Räder dadurch auf, dass innerhalb des Lenkventils Leckagen entstehen. Der eine Handpumpe verlassende Ölstrom steht also nicht vollständig im Servomotor zur Verfügung. Das fehlende Lecköl lässt sich nur durch zusätzliches Drehen am Lenkhandrad ersetzen. Die Leckage im Lenkventil entsteht hauptsächlich zwischen den an den Servomotor angeschlossenen HD-Nuten (24; 25) und den zum Behälter führenden ND-Nuten (22 bzw. 23), zwischen welchen beim Lenken ein hohes Druckgefälle entsteht. Man sieht deshalb zwischen den HD-Nuten und den ND-Nuten sogenannte Drucksperrnuten (42 bzw. 43) vor. Nach der Erfindung sind diese Drucksperrnuten über Kanäle (48 bzw. 50) an die Stirnseiten einer Bohrung (51)angeschlossen. In die Mitte der Bohrung (51) mündet ein an eine P-Nut (21) der Pumpe (14) angeschlossener Kanal (53). Die Bohrung (51) enthält einen Kolben (52), der in seinen beiden Endlagen den Kanal (53) mit der Drucksperrnut (42 oder 43) verbindet. Bei einer Lenkbewegung kann daher immer die Drucksperrnut (42 oder 43) der druckführenden HD-Nut (24 bzw. 25) mit dem Hochdruck der Pumpe (14) beaufschlagt werden. Durch diese Massnahme lassen sich die Drücke in der HD-Nut (24; 25) und in der benachbarten Drucksperrnut (42 bzw. 43) nahezu auf gleicher Höhe halten. Ein Durchsickern von Lecköl aus der HD-Nut (24; 25) zur ND-Nut (22 bzw. 23) kann somit unterdrückt werden.

Abstract: A helical drive system (10) reads tracks (18) on a storage medium (12), including tracks which appear as distorted tracks. Each track (18) comprises a plurality of blocks of data, with each block having unique block-identifying information. A track-following servo system (84) causes a read head (16C) to traverse predetermined original azimuthal paths (P0) across the storage medium (12) for reading the blocks recorded along each of the original azimuthal paths (P0). A controller (50) uses the block-identifying information to determine whether any blocks expected to be read during the traversal of the original azimuthal paths (P0) were not read. If expected blocks were not read, the controller (50) repositions the storage medium (12) and directs that the medium (12) be re-read with the head (16C) positionally offset until the expected blocks are actually read. During the re-read attempts, the read head (16C) is positionally offset to traverse sets of modified azimuthal paths (P1, P2, P3, . . . P10 ). Each set of modified azimuthal paths (P2, P3, . . . P10) is offset with respect to the original azimuthal paths (P0) relative to a direction of medium travel (15), thereby providing opportunities to read blocks which would not otherwise be read due to distortion of the tracks (18). In one mode of the invention, the controller (50) dynamically selects from among a plurality of offset degree values based on the historical success rate of the differing offsets in reading blocks which formerly were missing blocks.
