Abstract: Procedure and apparatus for the purification of air, flue gases or equivalent, in which procedure the air, flue gases or equivalent are directed into a duct or equivalent, in which procedure the air, flue gases or equivalent are ionized, and in which procedure the charged impurity particles (7) present in the air, flue gases or equivalent are attracted by one or more collector surfaces (2) by virtue of a difference in the states of charge, causing the particles to settle on said surface. The air, flue gases or equivalent are ionized by means of one or more ionizing electrodes (5) directed at a collector surface. The distance between the ionizing electrode,or equivalent and the collector surface as well as the difference between the states of electric charge of the collector surface and the charged impurity particles are so adjusted that the impurity particles will be carried by an ion beam essentially directly towards the collector surface and settle on it.

Title: Vial locator and sensor
Inventor: PENNATTO SAMSON
IPC: B01L9/00
Filed: 1991-02-07
Granted: 2001-06-12
Abstract: An analytical instrument sample vial positioning and sensor device. A radius or cone-shaped body portion extending below a surface contacts a loosely held sample vial having a flexible septum thereon. The shaped body portion is biased downward resulting in the relative movement between the sample vial and shaped body portion tending to center the flexible septum under the shaped body. A longitudinal bore extending through the shaped body permits the insertion of a syringe needle for the removal of a sample to be analyzed.      The pre-positioning of the sample vial prevents syringe needles from being bent or broken due to inappropriate alignment with respect to the septum. A sensor is incorporated with the shaped body to detect the presence or absence of a sample vial.

Granted: 1999-05-11
Abstract: A hybridoma cell line is provided which is capable of producing a monoclonal antibody which binds to a unique determinant site on the surface and in the cytoplasm of human breast carcinoma cells and carcinoma cells of other adenocarcinomas and does not bind selectively to the surface of normal human breast epithelial cells except in instances of high concentration of the antibody in the testing fluid.  The cell line of the invention was developed by immunizing mice with a select group of immunogens and a conventional myeloma cell line for fusion with the murine splenocytes harvested.  The monoclonal antibody is identified as the BrE3 monoclonal antibody.  The BrE3 mononclonal antibody binds to an antigen which is characterized as high molecular weight mucin-like glycoprotein complex having a molecular weight exceeding 400,000 daltons that is bound by a disulfide bond to a protein of 69,000 daltons.  The BrE3 mononclonal antibody is especially useful for diagnostic detection, prognostic, and possible therapeutic applications in human breast cell carcinoma.

Granted: 1997-05-27
Abstract: An apparatus (10) and method for facilitating the respiration of a patient are disclosed which are particularly useful in treating mixed and obstructive sleep apnea and certain cardiovascular conditions, among others, by increasing nasal air pressure delivered to the patient's respiratory passages just prior to inhalation and by subsequently decreasing the pressure to each exhala-tion effort. The preferred apparatus (10) includes a patient-coupled gas delivery device (14) for pressurizing the patient's nasal passages at a controllable pressure, and a controller (20) coupled with the delivery device (14) having a pressure transducer (700) for monitoring the nasal pressure and a microcontroller (802) for selectively controlling the nasal pressure. In operation, the con-troller (20) determines a point in the patient breathing cycle just prior to inhalation and initiates an increase in nasal pressure at that point in order to stimulate normal inhalation, and subsequently lowers the nasal pressure to ease exhalation efforts.

Granted: 2002-04-16
Abstract: In a combination tool bit and tool bit holder or chuck, rotary entrainment members (6, 7) extending over different circular arcs are formed in the tool bit holder for transmitting torque to the tool bit shank (8). Corresponding rotary entrainment grooves (9, 10), also extending over different circular arcs, are formed in the tool bit shank (8). Locking members (4) axially retain .the tool bit in the holder. The locking members (4) can be displaced radially into or out of the recesses (11, 12) in the tool bit shank (8). The recesses (11, 12) are laterally closed. Due to the different configurations of the rotary entrainment members (6, 7) and the corresponding grooves (9, 10) it is possible to transmit higher torques while avoiding detrimental cross-sectional weakening of the tool bit shank (8).

Granted: 2000-02-22
Abstract: Appareil et méthode pour effectuer un essai de pressurisation à basse pression servant à évaluer l'intégrité et à mesurer le taux de fuite dans un bâtiment hermétique. Après avoir pressurisé de quelques kilopascals 1e bâtiment et un volume de référence contenu dans un réseau de tubes arborescents dans le bâtiment, le volume de référence est isolé puis l'évolution de la pression différentielle en fonction du temps entre les deux est mesurée à l'aide d'un manomètre différentiel. Le réseau de tubes est fait de tubes de cuivre soudés les uns aux autres et dont le volume d'air de chacune de ses sections reproduit à l'échelle le volume de la zone du bâtiment où il est situé de façon à ce que la variation de la pression différentielle entre l'intérieur du bâtiment et le réseau soit nulle malgré une variation de température survenant dans le bâtiment. Un réseau d'échantillonnage de l'air permet de surveiller la pression partielle de certains gaz, comme par exemple la vapeur d'eau, afin de pouvoir, si nécessaire, corriger les données de la pression différentielle. L'appareil et la méthode s'applique notamment au bâtiment d'une centrale nucléaire dont le réacteur fonctionne à capacité maximale durant l'étude.

Granted: 2005-11-22
Abstract: In addition to virions, herpesvirus-infected cells produce non-infectious particles, termed L-particles, which consist of tegument surrounded by envelope but lack the nucleocapsid.      L-particles of a herpesvirus can be prepared substantially free of infectious virions, e.g. by allowing an appropriate temperature-sensitive mutant to replicate at its non-permissive temperature, and such L-particles are useful as a component of a vaccine against the herpesvirus. They can also be prepared to contain a foreign protein or peptide, by use of a recombinant herpesvirus.

Abstract: Oxygen is separated from air by pressure swing adsorption in plant 2. The oxygen is passed through an ozone generator 4. The resulting ozonated oxygen is passed upwardly through a contactor 6 countercurrently to the flow of a side stream of water to be treated with ozone. The side stream containing dissolved ozone flows from the contactor 6 to a mixer 8 in which it is mixed with a main stream of water. The effluent gas from the contactor 6 contains air displaced from the water and undissolved oxygen.      It is divided into two parts. One part flows to the pressure swing adsorption plant 2 and is separated therein with the air. The other part is dried by temperature swing adsorption in drier 20 and the resulting dried gas is ozonated in the ozone generator 4 with the oxygen from the plant 2.
