Abstract: The invention concerns the radio transmission of chronometric information. It relates in particular to a device comprising an antenna to which there are coupled on one hand a generator generating a signal to be sent and on the other hand a reception processing circuit capable of working on a received signal. According to a general aspect of the invention, the signals exchanged have the same carrier frequency. The device of the invention then comprises sequencing means able to define separate time segments with successive random positions. Transmission is enabled only during these time segments, whilst reception is enabled outside these segments, which makes it possible to use the time markers of the signals without any effect of recurrent masking of the reception by the transmission.

Granted: 2005-01-04
Abstract: A system for controlling front and tail end gauge of a continuous hot rolled product in a rolling mill includes first and second individually driven roll stands arranged successively along said pass line in advance of a group of roll stands. A controller adjusts the operating speed relationship between the first and second individually driven roll stands to achieve an increased level of tension in the front and tail end segments of the product passing between the first and second individually driven roll stands. The increased level of tension results in the decrease in product cross sectional area sufficient to compensate for the lack of cross sectional area reduction resulting from the absence of interstand tension experienced by said front and tail end segments while being rolled in the group of roll stands. To control the gauge of the front end of the continuous hot rolled product, the controller commands a decrease in the speed of the first roll stand as front end approaches the second individually driven roll stand, which is located adjacent to and downstream of the first individually driven roll stand. The reduction of the speed of the first roll stand below a nominal rolling speed establishes the increased level of tension of the product between the first and second roll stands when the front end enters the second roll stand. When the front end has passed the first roll stand, the controller commands the speed of the first roll stand to return to the nominal roll speed to roll the segment of the product between the front and tail ends. To control the gauge of the tail end of the product, the controller commands a decrease in the speed of the first roll stand as the tail end approaches the second individually driven roll stand.

Title: Reconfigurable air supply arrangement of an air-conditioning system for below-deck areas of a passenger aircraft
Inventor: MARKWART MICHAEL
IPC: B64D13/00
Filed: 2000-08-24
Granted: 2008-10-21
Abstract: The below-deck space of an aircraft may be selectively configured as a freight hold or alternatively as a passenger sleeping cabin space by arranging a sleeping cabin container therein. An air conditioning system for this below-deck space provides air in a supply air main line, which branches off to at least one supply air delivery line. A first flange is provided at the end of the supply air delivery line, and a seal collar seals the end relative to the freight hold wall. When a sleeping cabin container is to be arranged in the below-deck space, a flap door is pivoted into an open position, and the flange at the end of a ventilation duct of the sleeping cabin is connected directly to the flange. When the sleeping cabin container is removed from the freight hold, the flap door is pivoted into a closed position, in which it covers the mouth opening of the flange, and allows an air flow into the freight hold only through the smaller restricted cross-section of an air throughflow opening in the flap door. The air supply arrangement can be easily adjusted to meet the different air flow requirements of the sleeping cabin configuration and the freight hold configuration without requiring any recalibration of the air-conditioning system itself.

Abstract: A cut-resistant combined yarn is described that includes a wire component.  Kinking and knotting of the wire component resulting from stretching of the wire component during knitting is avoided by encasing the wire component within a cut resistant combined yarn that has a higher stretch resistance than the wire component. The combined yarn includes at least one strand of stainless steel, at first non-metallic strand of an inherently cut-resistant material, and a second non-metallic strand of a cut resistant material, a non-cut resistant material or fiberglass. The non-metallic strands are air interlaced with each other to form intermittent attachment areas along the lengths of the strands. At least one or the other of the strands is a multi-filament strand. During air interlacing operation, the two non-metallic strands encase the stainless steel strand in the non-metallic strands at least in some of the zones. A  composite yarn may be formed by wrapping at least one cover strand wrapped about the combined yarn in a first direction. A second cover strand may be wrapped about the combined yarn in a second direction opposite the first direction.
