Title: Cellule de memoire dynamique adressable par le contenu
Inventor: LINES VALERIE
IPC: H01L27/108
Filed: 2000-03-30
Abstract: L'invention concerne une cellule de mémoire dynamique adressable par le contenu (CAM) permettant de construire des matrices de mémoires CAM relativement rapides et de capacité relativement importante, pouvant stocker des données binaires et ternaires. Ladite cellule comprend une paire de dispositifs de stockage, des moyens de comparaison et une paire de dispositifs d'accès mémoire. Au cours d'une opération de comparaison, les moyens de comparaison couplent une ligne de concordance à une ligne de décharge pour les cas où une paire de bits de recherche complémentaires véhiculés sur une paire de lignes de recherche et une paire de bits de données complémentaires stockés dans la mémoire ne coïncideraient pas. Lors d'une opération de lecture ou d'écriture, la paire de dispositifs d'accès est activée par un ligne de travail de manière à coupler les condensateurs de stockage à une paire de lignes de bits. Un bit utile '0' ou '1' est mémorisé lorsque les deux condensateurs de stockage véhiculent des charges complémentaires. Un état 'ignorer' est mémorisé lorsque les deux condensateurs sont déchargés.

Abstract: A vehicle seat assembly having a molded foam cushion body (14) and a pair of molded foam bolster bodies (20, 22) covered by a cover member (28) which is bonded to the cushion body and the bolsters during molding. The cushion body foam (24) is poured in place onto a portion of the cover member (28) and the foam (26) for the bolster bodies (20, 22) is poured in place adjacent the cushion body (14) preferably at the same time.

Title: Radial immunodiffusion and like techniques
Inventor: BRADWELL ARTHUR R
IPC: G01N33/559
Filed: 1990-04-25
Abstract: ABSTRACT       RADIAL IMMUNODIFFUSION AND LIKE TECHNIQUES         In a known method of immunodiffusion, a sample containing a first agent such as an antigen is introduced into a well  in a lamina of agarose gel containing a second agent such as a complementary antibody.   The first agent diffuses through the gel and becomes releasably bound to the second agent and, when the concentrations of agents are optimal,  the agents form an extended matrix incorporating light-scattering aggregates.  The size of the visible matrix enables the concentration of one of the agents to be assessed when that of the other agent is known.  Each aggregate comprises very large numbers of the molecules of the agents.   The invention provides an improved method in which the second agent is attached to  carrier means in the gel (3) so that the carrier means constitutes part of the visible aggregations.   The carrier means may constitute the gel itself and/or it may constitute particulate material such as polystyrene particles.

Title: Bispecific and oligospecific mono- and oligovalent receptors, the preparation and use thereof
Inventor: BOSSLET KLAUS
IPC: C07K19/00
Filed: 1990-06-21
Abstract: The invention relates to bispecific and oligospecific, mono- and oligovalent receptors which are prepared by gene manipulation by fusion of DNA coding for F(ab) fragments of antibodies of two or more different specificities by means of suitable linkers. In this connection, one specificity is preferably directed either against an epitope, which is located on the cell membrane or in the interstitium, of a tumor-associated antigen (TAA) or against an epitope in the tumor endothelium (TE), while the other specificities relate to highmolecular or low-molecular weight ligands and react, for example, with the Komplexons ethylenediaminetetraacetate and diethylenetriaminepentaacetate in Y90 complexed-form (EDTA-Y90 and DTPA-Y90 respectively). In a particularly preferred embodiment, the binding with the Komplexons takes place on the Komplexon receptor arm via fos-jun interaction (or else avidin-biotin interaction). Other preferred specificities have catalytic properties.

Abstract: SUMMARY      Abstract The invention concerns an adjustable drive, specifically for a printingpress, with an electric driving motor, linked via a reduction gear to an adjusting shaft and via a drive unit to a position indicator.   This invention is intended to produce an adjusting drive which in terms of different setting requirements offers a variable, simple solution based on compact design that will match the adjusting drive requirements in each case.   To this end, the reduction gear (4) and/or the drive unit (5) are equipped with two parallel bearing shafts (53, ... 58, ...).  On each of these, reduction gears (65, 70) of a given number and/or diameter, consisting of a pinion (67, 71) non-rotatably connected to a spur gear (66, 69), are mounted interchangeably in such a way that the pinion (67, 71) and spur gear (66, 69) can mesh with reduction gears (65, 70) mounted on different bearing shafts (53, ... 58 ...).

Abstract: As-mined, naturally water-wet oil sand is mixed at the mine site with hot water, air and NaOH to produce a slurry.  The slurry is pumped through a pipeline at least about 2.5 kilometres in  length  and  is  fed  directly  to  a  conventional  gravity separation vessel.   In the course of being pumped through the pipeline, sufficient coalescence and aeration of bitumen occurs so that, when subsequently retained in the vessel under quiescent conditions,  a desirable amount of  the  bitumen  floats,  forms froth, and is recovered.

Title: Modular higher density communications coupling system
Inventor: ROBINSON SCOTT T
IPC: H01R24/62
Filed: 1991-01-14
Abstract: A modular higher density communications coupling system including a universal platform for supporting multiple connectors from a single outlet hole is disclosed. The platform includes a main body member having a registration ridge extending forward of the main body member for extending into a standard sized outlet hole. A pair of apertures adjacent to each other extend through the main body member and are generally surrounded by the registration ridge. A pair of connector housings are attachable to the sear of the platform in alignment with the apertures for housing connectors. A pair of retaining members on two sides of the apertures hold the connector housings in position. A pair of support members extend rearwardly from the main body of the platform on the other two sides of the apertures. A termination plate is mounted in the support members, the termination plate having a plurality of electrical couplings for connecting the wire from a wall to the connector. A grounding screw mount provides easy access from the front, side or rear. The relationship between the retaining members, apertures, and support members facilitates a higher density of electrical couplings than previously possible in the prior art. Telecommunications apparatus of the type identified within the specification, in combination with the aforesaid, is contemplated as coming within the scope of the present invention.

Filed: 1991-01-17
Abstract: A method of and apparatus for roller expanding an insert inside the damaged inlet end of a parent tube uses spacers between the stops on the mandrel and on the tapered rod of the roller expander. The spacers prevent the tapered rod from expanding the insert more than a pre-set amount, thus preventing over or under expansion  of  the  insert.  The  relative  stopping positions of the stops on the mandrel and on the tapered rod are adjusted so that the tapered rod is slidable into the mandrel no further than is required to  expand  the  insert  to  an   inner  diameter substantially equal to the inside diameter of the parent tube less the thickness of the insert.

Abstract: METHOD AND APPARATUS FOR VERIFICATION OF PASSWORDS                 Abstract of the Disclosure Methods and apparatus for verifying the acceptability of a password proposed by a user of a secure system.  The system stores a compressed version of a group of unacceptable passwords in a table of indicators.  A mapper assigns indicators to passwords, such that more than one password may be mapped to a indicator.  To initialize the system, an initializer applies the mapper to each unacceptable password of the group, and sets the indicators of the table that are assigned to each unacceptable password.  Subsequently, a verifier applies the mapper to a proposed password and checks whether the indicator assigned to the proposed password is set.  If the indicator is not set, it is determined without error that the proposed password is not in the group of unacceptable passwords, and may thus be assigned privileges in the secure system.
