Abstract: The present invention is directed to a novel polymodal asymmetric elastomeric block copolymer and a pressure sensitive adhesive and tape made therefrom. The novel block copolymer comprises from about 4 to about 40 percent by weight of a polymerized monovinyl aromatic compound and from about 96 to about 60 percent by weight of a conjugated diene. The block copolymer has the general formula Q n Y where Q represents an individual arm of the block copolymer and has the formula S-B; n represents the number of arms and is at least 3; and Y is the residue of a multifunctional coupling agent.  Furthermore, S is a nonelastomeric polymer segment endblock of a polymerized monovinyl aromatic homopolymer, there being at least two different molecular weight endblocks in the block copolymer. The number average molecular weight of the higher molecular weight endblock (Mn)H  is in the range of from about 5,000 to about 50,000, and the number average molecular weight of the lower molecular weight endblock (Mn)L is in the range of from about 2,000 to about 10,000. The ratio (Mn)H/(Mn)L is at least 1.25. In addition, B is an elastomeric polymer segment midblock which connects each arm to a residue of a multifunctional coupling agent (Y) and comprises a polymerized conjugated diene or combination of conjugated dienes.

Abstract: The present invention provides a method for identifying or selecting from a population of eukaryotic cells cultivated on or in a medium containing at least one compound, cells which have a metabolic advantage as a result of having being transformed, wherein: (i) the cells are transformed with a nucleotide sequence or a co-introduced nucleotide sequence one of which comprises a region which: (a) encodes a protein which is involved in the metabolism of the compound, and/or (b) regulates the activity of the protein; and (ii) the compound is mannose or xylose or a derivative or a precursor of these, or a substrate of the protein, or is capable of being metabolized by the transformed cells into such a substrate, with the proviso that the compound is not mannos when the proteine is mannose 6 phosphate isomerase. The invention also includes a method according to the preceding paragraph wherein the compounds are are not so limited with the proviso that an agent which reduces the toxicity to the cells of the compound is added to the medium. It is preferred that where a toxicity-reducing agent has been added to the culture medium, the compound is mannose and the nucleotide or co-introduced nucleotide sequence encodes mannose-6-phosphate isomerase.

Title: Field replaceable connector for seismic instrument
Inventor: CHAMBERLAIN DONALD G
IPC: H01R31/06
Filed: 1995-09-28
Granted: 2001-04-03
Abstract: A removable connector operable to be inserted between a main cable carrying seismic information and a box connector of a remote acquisition module. The removable connector is adapted to isolate any forces arising in the main cable from the box connector of the module. The removable connector is removably secured to the remote acquisition module by a pin which extends through the housing of the removable connector and a bracket mounted to the module. The pin transfers the cable forces to the remote acquisition module and substantially isolates the box connector from such forces thereby extending the life of the box connector.

Abstract: A multiple phase stethoscope has a chest piece with a plurality of diaphragms and an equal plurality of sound compartments.  Sound is carried from each of these compartments through a separate lumen, the plurality of lumens making up a tube assembly.  The lumens are at least partially separated from each other by a flexible membrane which serves as a transducer to convert acoustic energy into mechanical motion, thus allowing the sound in the lumens to be combined.  One of the lumens is open to the atmosphere through ear pieces, while the other lumen is sealed with a material and/or pressure different from the ambient environment.  The geometry of the diaphragms, the second compartments, and the lumens; the materials used for the flexible membrane in the lumens; and the pressure of the material in the lumens are all selected to enhance and/or attenuate at least a part of a frequency spectrum of the sounds.  If two outer lumens are provided and are different around branches leading to the separate ear pieces, a stereophonic effect is created.  This effect can be obtained by altering materials or geometry, e.g., by spiraling the outer lumen around the branches at different angles.

Title: Automated wireless-call completion using a paging network
Inventor: GAULKE DAVID ALAN
IPC: H04B7/26
Filed: 1996-12-10
Granted: 2000-12-05
Abstract: In a cellular telephone system (FIG. 1), a pager (122) is associated with a cellular phone (121) that is normally kept turned off and thus not drawing power from its battery (513). When an incoming call for the cellular phone arrives at a cellular exchange (103) and the exchange determines that the cellular phone is not registered with a base station (107-109), a paging system (105) is caused to transmit an incoming-call-indicative paging signal to the pager. Receipt of this paging signal at the pager either causes the user of the pager and the cellular phone to turn on the cellular phone, or causes the pager to turn on the cellular phone automatically via associated circuitry (502, 515). Activation causes the cellular phone to register with a base station, whereupon the cellular exchange extends the incoming call to thecellular phone through that base station. If the incoming call is not answered, or when the incoming call is completed, the paging system is caused to transmit a second paging signal to the pager. Receipt of the second paging signal at the pager leads to the cellular phone being turned off again. The cellular phone can therefore normally be turned off without fear of missing incoming calls. Battery power of the cellular phone is thus conserved.

Granted: 2007-05-15
Abstract: This invention is directed to an efficient cryopreservation package desgin of harvested mammalian tissues and living cultured tissue equivalents made by in vitro technology. The invention involves immersing a mammalian tissue or cultured tissue equivalent in a cryoprotectant solution, agitating the cryoprotectant solution and the immersed tissue to achieve effective penetration of the cryoprotectant solution into the tissue, and then freezing the tissue at a very slow freezing rate. In the freezing step, extracellular ice formation is initiated by seeding. The cryopreserved tissue may be stored for indefinite periods of time prior to use. The cultured tissue equivalent is an in vitro model of the equivalent human tissue, such as skin or cornea, which, when retrieved from storage can be used for transplantation or implantation in vivo or for screening compounds in vitro.

Filed: 1996-03-28
Granted: 2005-03-22
Abstract: La présente invention concerne un appareil et un procédé d'extraction du signal d'horloge pour horodateur synchrone à temps résiduel (SRTS). L'appareil comprend essentiellement un générateur pilotable de signaux d'horloge (37) au noeud de destination, tel qu'un oscillateur à commande numérique, un bloc (36, 38, 40) servant à produire une valeur locale relative à l'horodateur à temps résiduel (RTS) à partir de l'horloge (37) du noeud de destination et de l'horloge (10) de référence du système ainsi qu'un comparateur (50) qui compare la valeur d'entrée liée à l'horodateur à temps résiduel et la valeur locale liée à l'horodateur à temps résiduel afin de fournir un signal de rétroaction d'erreur ou de commande, qui est utilisé pour régler le générateur d'horloge pilotable (37). Si on le souhaite, il peut y avoir dans la boucle un filtre (52) qui filtre le signal d'erreur. Avec la boucle de réaction selon l'invention, quand l'horloge (37) du noeud de destination est plus rapide que l'horloge source, le signal d'erreur a pour effet de ralentir l'horloge (37) du noeud de destination, et vice-versa.

Title: Article support
Inventor: GOYETTE PAUL D
IPC: A47B96/18
Filed: 1998-01-28
Granted: 2007-06-26
Abstract: An article support such as a shelf or a table top has a frame that, in its heated state, slidably receives a glass or plastic planar sheet into grooves along two opposing edges of the frame, until an end of the sheet abuts a third edge of the frame that joins the two opposing edges. The edges of the frame have lips that rest on a portion of the top surface of the sheet. When cooled, the frame contracts such that the edges of the sheet are tightly engaged within t:he grooves of the frame and the lips tightly abut the top Surface of the sheet, thereby creating an article support that resists spills around its periphery. The frame may be reheated to expand the material of the frame, permitting removal of the sheet from the frame. Thus, the frame and the sheet may be recycled.
