Title: Filin resistant a la rupture a lignes multiples
Inventor: FORWARD ROBERT L
IPC: B63B21/50
Filed: 1997-04-22
Abstract: L'invention concerne un filin (Fig. 6) présentant la caractéristique technique spéciale de posséder plusieurs lignes porteuses primaires (601, 603) et lignes secondaires (605, 603) à relâchement normal. Ces lignes primaires et secondaires sont reliées par des lignes de connexion sans noeud, sans décrochement, de telle sorte que le filin garde une résistance élevée et que certaines des lignes puissent être coupées sans qu'il y ait rupture du filin lorsque la coupure se fait près de la dernière charge de rupture de la matière dans laquelle il est réalisé. Ce filin peut en toute sécurité supporter (Fig. 31) des charges durant des périodes cent fois plus longues que les filins déjà existants, dans des environnements hostiles où un filin à ligne unique est soumis à un risque important de rupture. Le concept général de la présente invention concerne également les applications industrielles spécifiques d'un système de filin électrodynamique destiné à désatelliser des satellites et d'un système de transport par filin à partir d'une orbite basse vers une surface lunaire.

Patent EP-0906778-A1 (EP)
Inventor: WILLIAMS TERRELL J
IPC: B07B1/50
Filed: 1998-09-23
Abstract: A pair of cylindrical composite rollers formed of a metallic drum having a
thick outer elastomeric layer are mounted transversely in a rectangular frame
of a drilling mud separation unit over which a wide endless-loop chain-link belt
is driven in a continuous loop moving along the longitudinal axis of the frame.
The drive roller has a plurality of axially spaced circumferential rows of radially
extending teeth that are machined in the surface of the elastomeric material.
The endless belt is formed of a plurality of laterally adjacent jointed links hinged
together by transverse rods. As drilling mud or drilling fluids are conducted
onto the moving belt, liquids and particles smaller than the openings in the belt
pass through the openings and liquids and particles larger than the openings
are transported on the moving belt and are discharged off of one end as the
belt completes its path. The teeth of the drive roller are sized and spaced to
receive and engage the plurality of laterally adjacent jointed links of the wide
belt and are of sufficient length to protrude slightly beyond the outer surface of
the links as they pass around the front drive roller to dislodge gumbo and other
large solids which may otherwise stick in the openings of the links and clog the
belt. The elastomeric roller surfaces and teeth reduce wear and prevent
metal-to-metal contact and sparking.

Abstract: A method for removing a contaminant from a fluid feed stream containing the contaminant. The method includes the steps of providing a feed stream and heating it in a first step to at least partially remove some of the contaminants and recover energy from a concentrate and distillate generated. Further heating the feed stream in a second heating step in a heated separator generates a saturated vapor fraction and a concentrated liquid contaminant fraction. The vapor fraction may be compressed to generate a temperature differential in the reboiler exchanger with the vapor fraction being passed into contact with a reboiler exchanger to provide a stream of condensed vapor from the reboiler. The stream may be circulated through the reboiler exchanger and the heated separator to maintain from about 1% to about 50% by mass vapor in the stream. The apparatus includes a unique configuration of a vapor compressor, heated separator in combination with a forced circulation circuit to generate the decontamination result.

Title: Position indicator
Inventor: DOHNAL DIETER
IPC: H01H9/00
Filed: 1998-01-09
Abstract: A position indicator for a motor drive for actuating a step switch, tap changer, or dipping coil, has a display board having front and back faces and a first circular array of symbols on the front face corresponding to individual switching phases traversed during changeover of the motor drive from one operational position into another neighboring operational position. A first shaft extending through the board centrally of the first array and defining a first axis carries a pointer at the front face rotatable about the first axis through positions aligned with the symbols. A second circular array of symbols on the front face is associated with individual possible stationary operational positions of the step switch, the tap changer, or the dipping coil. A second pointer shaft projecting through the board centrally of the second array and defining a second axis carries a second pointer at the front face rotatable about the second axis through positions aligned with the symbols of the second array. Respective trailing pointers pivotal on the second axis and not driven by the second shaft flank the second pointer and have entrainment formations engageable therewith. Thus as the second pointer moves and engages either of the pointers it displaces same. A gear mechanism on the back face connects the second shaft to the first shaft for movement of the second pointer angularly codirectionally with the first pointer between adjacent symbols of the second display on rotation of the first pointer through 360°.

Abstract: Magnetronentladungen werden gepulst betrieben, um das sogenannte "arcing" zu vermeiden. Bei mit Wechselstrom gespeisten Magnetronentladungen ist das Verfahren auf geringe Leistungen der Energieeinspeisung aufgrund der Belastbarkeit der notwendigen elektrischen Bauelemente begrenzt. Werden die Magnetronentladungen mit Gleichstrom gespeist, verschlechtert sich durch die Bedeckung der Anodenflächen mit Schichtmaterial deren Wirkungsweise. Mit dem neuen Verfahren soll die Einspeisung hoher Leistungen ermöglicht und das "arcing" verhindert werden. In Magnetronentladungen mit mindestens zwei Magnetron-Elektroden wird die Energie derart zugeführt, dass mindestens je eine Magnetron-Elektrode Katode bzw. Anode ist und eine Anzahl n1 von Gleichstrompulsen in dieser Polung eingespeist wird. Anschliessend erfolgt ein Polwechsel mindestens je einer Magnetron-Elektrode und es wird eine Anzahl n2 von Gleichstrompulsen in dieser Polung eingespeist. In diesem Sinn wird das Verfahren fortgeführt, wobei die Frequenz der Gleichstrompulse grösser als die der Polwechsel ist. Dadurch wird die Wirksamkeit der Energieeinspeisung verbessert. Mit dem Verfahren und der Einrichtung lassen sich Schichten unterschiedlichster Eigenschaften z.B. für die Glas-, Verpackungs-, Elektronikindustrie oder den Maschinenbau herstellen.

Abstract: A relaxation oscillator, such as a voltage controlled oscillator (VCO), with automatic swing control feedback which dynamically monitors the voltage swing across a capacitor and adjusts the oscillator threshold voltage, at which reversal of the polarity of the charging/discharging current occurs, to maintain the effective voltage swing at a constant level.
