Title: Moteur a turbine dote d'une turbine a refroidissement par air
Inventor: LIU XIAOLIU
IPC: F02C7/12
Filed: 2002-10-18
Abstract: L'invention concerne un moteur à turbine (10), dans lequel l'air à basse température est dévié d'une partie à basse pression de la partie compresseur du moteur en vue de refroidir la turbine à haute pression du moteur. L'air à basse pression est dévié de la partie compresseur et sa pression est, par la suite, augmentée. La pression est augmentée dans une cavité intermédiaire (80) du moteur, où l'énergie de rotation de l'air dévié est transformée en pression statique par le biais d'une obstruction (88) qui convertit la charge dynamique de l'air dans la cavité en pression statique.

Title: Gap sealing means
Inventor: RIEDERER RUDOLF
IPC: B60J1/00
Filed: 1990-02-26
Abstract: ABSTRACT     In a vehicle body, the aperture for the pane or window comprises a mounting flange stepped towards the interior of the vehicle. The pane or window is adhesively fixed to that mount-ing flange along a peripheral edge portion. Along the edge of the mounting flange remote from the aperture for the pane or window a gap sealing member is adhesively fixed to the stepped portion of the mounting flange. The gap sealing member is an endless hollow profile member corresponding in size to the perimeter of the pane or window and is elastically deformable.          The use of such a gap sealing member is much less expensive than known sealing members of this kind, offers good appearance and may be easily mounted while it effectively seals the gap between vehicle body and pane or window against dirt and moisture.

Title: Intake device for multi-cylinder internal combustion engine
IPC: F02B27/02
Filed: 1990-05-28
Abstract: In an intake device for a multi-cylinder internal combustion engine, comprising a pair of resonance chambers and a pair of resonance passages, the resonance chambers and the resonance passages are disposed in parallel in a V-space in the internal combustion engine with a dividing wall interposed therebetween, thereby providing a compact intake system.  In the intake device, the resonance chambers are defined in one of upper and lower assembly box portions, while the resonance passages are defined in the other assembly box portion, and an on-off valve capable of changing suction characteristics of the internal combustion engine is provided in a plate-like valve unit separating and joined to the opened surfaces of the two box portions.  This enables a reasonable layout of the on-off valve.  Further, in the intake device, the resonance chambers are capable of communicating with each other through a communication chamber having a predetermined volume.  This ensures both a resonance supercharge effect and an inertia supercharge effect.

Title: Method of and apparatus for measuring the mean concentration of thoron and/or radon in a gas mixture
Inventor: LUCAS HENRY
IPC: G01T1/178
Filed: 1990-07-31
Abstract: Abstract of the Disclosure A method of and an apparatus for detecting and accurately measuring the mean concentrations of 222Rn and 220Tn in a gas mixture, such as the ambient atmosphere in a mine, is provided.  The apparatus includes an alpha target member which defines at least one operative target surface and which is preferably fabricated from a single piece of an alpha particle sensitive material.  At least one portion of the operative target surface is covered with an alpha particle filter.  The uncovered and filter covered operative surface is exposed to the gas mixture containing the 222Rn and 220Tn.  In the radioactive decay series of these isotopes the maximum kinetic energy emitted by the alpha decay of 222Rn is about 1.1 MeV less than the maximum kinetic energy emitted by the alpha decay of a 220Tn.  The alpha particle filter has a predetermined mass per unit area of the covered portion of the operative target surface that prevents penetration of alpha particles which originate from 222Rn decay, but which allows passage therethrough of the maximum kinetic energy alpha particles from 220Tn decay.          Thus, a count of the alpha particle tracks in the uncovered portion of the target member is proportional to the mean concentration of sum of 222Rn and 220Tn in the gas mixture, while the count of alpha tracks in the target member under the filter is proportional to the concentration of only the 220Tn in the gas mixture.

IPC: H04B7/22
Filed: 1990-11-09
Abstract: ABSTRACT          A meteor scatter communications system for communicating between a master station (10) and one or more remote stations (11).  In one exemplary embodiment, a broad beam transmitter probe signal (30) is reflected from a meteor ionization trail to a remote station which then transmits a return data signal to the master station.  The master station receiver has a plurality of antennas (27-I ... 27-N) and a receiver beam forming network (28) which forms a plurality of narrow beam receive signals (32-I ... 32-N), one of which (32-X) has a high gain and corresponds to the narrow beam signal which illuminates the meteor trail and contains the reflected return data signal from the remote station.  The master station processor (12) selects such one narrow beam signal for processing the data therein.  The transmitter at the master station, if desired, can then transmit a further narrow beam message signal containing a message to the remote station using a transmit beam forming network (36) to provide a selected narrow beam transmit signal for reflection from the meteor trail to the remote station.

Title: Byte wide elasticity buffer
Inventor: HAMSTRA JAMES R
IPC: G06F5/06
Filed: 1990-11-13
Abstract: Abstract BYTE-WIDE ELASTICITY BUFFER A network station's elasticity buffer includes a memory core together with write and read pointer logic.  The memory core includes a START area and a CONTINUATION area which is a cyclic buffer.  Under normal conditions, the read pointer follows the write pointer cyclically in the CONTINUATION area. However, upon detection of a start delimiter or upon station reset, the pointers recenter to the START area.  Separate synchronizing logic is provided for each of the two recentering modes to reduce metastability problems caused by asynchronous sampling of data.  A delay-by-one mechanism is built into the start delimiter mode synchronization scheme so that, under certain conditions, the read pointer is held in the CONTINUATION area for an additional read so an early sample of the read-start signal by the station's local clock while the read pointer is well behind the write pointer will not drop the last character of the previous frame when that frame is not separated from the next start delimiter by a sufficient interframe gap.  A look-ahead-look-current detector insures that the there is not too much initial separation between the write pointer and the read pointer.  A delay-GO mechanism is built into the reset mode synchronization scheme to prevent irregular dropping of line state characters when the local byte clock is trapped within the metastability window while clock drift is infinitesimal.  The read pointer logic also includes a mechanism for preventing the delay-GO mechanism from creating too much initial separation between the write pointer and the read pointer.

Title: Method for implanting large volumes of cells on polymeric matrices
Inventor: VACANTI JOSEPH P
IPC: A61F2/02
Filed: 1990-04-25
Abstract: The present invention is a method and means whereby large volumes of cells having a desired function are attached to, and, optionally, proliferated, on a biocompatible degradable, non-degradable or combination degradable-non-degradable scaf-folding and transferred with mininal trauma and blood loss into a patient at a site appropriate for attachment, growth and func-tion to produce a functional organ equivalent in the absence of vascularization of the implanted cell mass. In the preferred em-bodiment multiple cell-matrix structures are implanted between folds of the mesentery. The method is particularly well suited for growth of endocrine structures, including liver, pancreas, and adrenal gland, as well as other tissues. The preferred material for forming the matrix or support structure is a biodegradable artificial polymer.  Materials such as angiogenesis factors can be incor-porated into degradable matrices for use in preparing the implantation sites prior to, or at the time of, implanting the calls. The function and viability of the attached cells can also be manipulated by treatment or coatiing of the matrix structure to increase the number of attachment sites.
