Title: Telephonic telemeeting system
Inventor: PILLET MICHEL
IPC: H04M3/60
Filed: 1992-05-13
Granted: 1996-05-14
Abstract: A telemeeting system comprises a terminal connected to the telephone network by telephone lines attributed to participant telephone sets. A console connected to the telephone set of one of the participants acting as organizer assists the latter in reflecting remarkable operations carried out by the terminal. These operations are indicated in a display board of indicator lights on  the  console  and  can  be  the  result  of  commands transmitted by the organizer telephone set, such as a calling of a participant, inaccessibility of a line or the programming of a terminal operating mode, and of signallings such as the seizing or releasing of a line by a participant. The system also permits  transmission  of  indications  from  each  of  the participants to the organizer, even if the participant does not have the right to speak, consultation of call number lists and time  intervals  of  telemeetings  in  the  terminal  from  the organizer, and automatical setting-up of participant calls for a telemeeting from the terminal.

Title: Assay method utilizing induced luminescence
Inventor: ULLMAN EDWIN F
IPC: G01N33/542
Filed: 1992-05-21
Granted: 2007-07-31
Abstract: Methods are disclosed for determining an analyte in a medium suspected of containing the analyte.   One method comprises treating a medium suspected of containing an analyte under conditions such that the analyte, if present, causes a photosensitizer and a chemiluminescent compound to come into close proximity.  The photosensitizer generates singlet oxygen and activates the chemiluminescent compound when it is in close proximity. The activated chemiluminescent compound subsequently produces light. The amount of light produced is related to the amount of analyte in the medium. Preferably, at least one of the photosensitizer and chemiluminescent compound is associated with a surface which is usually a suspendible particle, and a specific binding pair member is bound thereto.   Another method comprises providing (1) a medium suspected of containing the analyte, (2) a label reagent comprising a first specific binding pair (sbp) member associated with a photochemically activatable chemiluminescent compound wherein the first sbp member is capable of binding to the analyte or to a second sbp member to form a complex related to the presence of the analyte. This method further comprises photochemically activating the chemiluminescent compound. The amount of luminescence generated by the chemiluminescent compound is detected. The amount thereof is related to the amount of analyte in the medium.   Compositions and kits are also disclosed.

Inventor: WALTZ ALBERT J
IPC: G05B11/32
Filed: 1990-11-02
Granted: 2001-01-16
Abstract: Un moyen permet de commander un processus caractérisé par une multiplicité de mesures dépendantes d'un paramètre du processus, de sorte que seule la mesure la plus restrictive détermine le processus, la performance de chaque dispositif individuel de commande sélectionné étant équivalente à leur performance dans les cas où seul un dispositif de commande commande une seule mesure, celle de la variable la plus restrictive. Le moyen de commande règle le processus de façon à éviter qu'une mesure à l'intérieur de limites restrictives du processus ne dépasse excessivement ces limites restrictives du processus lorsque des projections montrent qu'elle les dépasserait si un réglage de correction n'était effectué.

Title: Plasma accelerator with closed electron drift
Inventor: ARKHIPOV BORIS A
IPC: H01J27/14
Filed: 1992-10-20
Granted: 1998-12-22
Abstract: Internal and external magnetic screens made of magnetic permeable material are added between the discharge chamber and the internal and external sources of magnetic field, respectively.  A longitudinal gap is maintained between the screens and their respective internal and external poles, that does not exceed half the distance between the internal and external poles.  The exit end part of the internal magnetic screen is placed closer to the middle point of the accelerating channel than the internal pole.  The walls of the exit end part of the discharge chamber are constructed with an increased thickness, and extend beyond the planes that the poles lay.  The magnetic screens can be located with a gap relative to the magnetic path if connected by a bridge between the screens.         The discharge chamber, the anode, and the magnetic system are symmetrically designed relative to two mutually perpendicular longitudinal planes.  Thus, the external pole and the external screen are made into four symmetrical parts relative to the planes; and the external sources of the magnetic field are made with four magnetic coils, each coil connected with one part of the external pole.  The discharge chamber is connected to the external pole with a holder at its front part.  The holder, with the exception of the locations of attachment, is situated with a gap relative to the discharge chamber and the external pole.

Title: Methods for the production of hybrid seed
Inventor: CROSSLAND LYLE D
IPC: A01H5/00
Filed: 1993-09-22
Granted: 2005-06-14
Abstract: The present invention provides a dual method for producing male-sterile plants. Two genetically transformed plants, parents 1 and 2 are crossed to obtain male-sterile offspring. Parent 1 is transformed with an expression cassette comprising a nucleotide sequence encoding an anther-specific promoter which is operably linked to a nucleotide sequence encoding a transactivator. Parent 2 is transformed with an expression cassette comprising a target nucleotide sequence, which is capable of being activated by the transactivator, operably linked to a nucleotide sequence which encodes RNA or a polypeptide which will disrupt the formation of viable pollen. Therefore, crossing parent 1 with parent 2 results in male-sterile offspring. The male-sterile plants are useful for producing hybrid seed. The invention also provides compositions and methods for high level expression of a coding region of interest in a plant.

Title: Three-axis stabilized, earth oriented satellite and corresponding sun and earth acquisition device
Inventor: SURAUER MICHAEL
IPC: B64G1/36
Filed: 1992-09-04
Granted: 2002-11-12
Abstract: A three-axis stabilized, earth-oriented satellite has an attitude control system with regulators, actuators, an earth sensor that carries out measurements along two axes and a sun-sensor arrangement that also carries out measurements along two axes. The field of view of the sun-sensor arrangement covers the round angle on a plane of the satellite-fixed coordinate system. Only the sun-sensor arrangement and the earth sensor act as measurement transducers. A sun and earth acquisition process for such a satellite has the following steps: seeking the sun; setting the sun vector in a first direction of reference; setting the speed of rotation of the satellite around the sun vector at a constant value; setting the sun vector in a second direction of reference, so that by rotating the satellite around the latter the optical axis of the earth sensor sweeps over the earth; and picking up the earth. Special regulating rules are disclosed.

Patent CA-2131668-C (CA)
Inventor: GALLI CAROL
IPC: H01L21/76
Filed: 1994-09-08
Granted: 1999-03-02
Abstract: A shallow trench isolation structure is formed by a process having a reduced number of steps and thermal budget by filling trenches  by  liquid  phase  deposition  of  an  insulating semiconductor oxide and heat treating the deposit to form a layer of high quality thermal oxide at an interface between the deposited oxide and the body of semiconductor material (e.g. substrate) into which the trench extends.  This process yields an isolation structure with reduced stress and reduced tendency to develop charge leakage.   The structure can be readily and easily planarized, particularly if a polish-stop layer is applied over the body of semiconductor material and voids  and  contamination  of  the  deposited  oxide  are substantially eliminated by self-aligned deposition above the trench in the volume of apertures on a resist used to form the trench.
