Abstract: The preparation and isolation of biodegradable superparamagnetic MR imaging contrast agents for the vascular compartment is described. These aggregates are comprised of individual biodegradable superparamagnetic metal oxide crystals which aggregates have an overall mean diameter less than about 4000 angstroms. The preferred vascular imaging contrast agent is comprised of aggregates of iron oxide crystals having an overall mean diameter less than about 500 angstroms. These contrast agents may be associated with a macromolecular species, which assist, among other things, in the preparation of these extremely small materials, and may be dispersed or dissolved in a physiologically acceptable medium. Preferred media also stabilize the materials against further aggregation even under harsh sterilization conditions. The autoclaved biodegradable superparamagnetic iron oxides of the invention are ideally suited for a pharmaceutical preparation and enjoy several advantages over prior intravascular imaging contrast media including low osmolality, low effective dose requirements, high relaxivities, long blood lifetimes, rapid biodegradability, and versatility with respect to a wide range of applicable MR data acquisition parameters.

Abstract: The present invention relates to an apparatus and method and uses a thin, yet strong plastic film (1) as the intermediate layer for the waterproofing material and the film has a plurality of perforations (2) therein. The film is highly resistant to crack propagation, and acts as a barrier to crack propagation between adjacent asphalt layers (5, 6), thus providing superior protection from the elements. The asphalt layers are interconnected with each other through the perforations in the polyester support layer. Because of the strength of the polyester film, only a very thin layer of polyester is necessary and this results in a substantial cost savings. As an alternative to coating, it is possible to extrude or laminate the asphalt onto the PET film. Also a layer of asphalt may be applied only to one side of said film and extruded through the perforations with heads on the columns (8) so formed to attach the asphalt to the film.

Abstract: The invention comprises the use of a memory in which each virtual circuit is allocated a location containing a context (CT), defining the conditions for evaluating the bit rate of this virtual circuit, and provides, upon the reception of each cell, for the reading of the context of the virtual circuit to which this cell belongs. A clock is set aside in order to supply a current time associated with this virtual circuit. 
<??>A measurement interval start time indicator is recorded in the context (CT) of a virtual circuit, upon the arrival of a first cell of this virtual circuit. Upon the arrival of a following cell of this same virtual circuit, the context is read and from the current time (hc) is subtracted the measurement interval start time. The time difference is compared with a specified duration of measurement interval and the number of cells already received is incremented. This number of cells already received is supplied as a measure of the average bit rate of the virtual circuit, when the said time difference is equal to or greater than the duration of measurement interval. The context is then reinitialised.

Abstract: A retinal blood flow velocimeter projects an illumination beam through a steering system onto a retinal vessel, and forms a separate tracking image back through the steering system. A fast tracking loop detects motion of the tracking image and moves the steering system to null image motion and keep the illumination beam centered on the vessel. The beam is reflected from the vessel, picked up by detectors at two fixed angles, and processed by spectral analysis. In one preferred embodiment the illumination beam and the steering system follow entirely separate paths through the steering system. Fiber optics translate the collected Doppler light without dispersion while preserving phase relationships, and absolute dimensions are determined from the image tracking electronics. A processor then computes volumetric blood flow which it compares with normative data.

Abstract: This system makes use of a tape cassette helical scan tape transport and 3480-type magnetic tape cartridge as the data storage media. The merging of these two incompatible elements is accomplished by the use of a novel interface that implements a "virtual tape cassette" using a tape cartridge in a manner that makes this media compatible with the tape transport. The virtual tape cassette is implemented by providing a takeup reel positioned with the magnetic tape cartridge in a relationship that substantially matches the format of a magnetic tape cassette. A short tape threading arm is used to retrieve the leader block from the tape cartridge and thread the magnetic tape over a short tape threading path to the takeup reel. Once the tape is affixed to the takeup reel, the helical scan tape guide arms transport the length of tape that is now exposed between the tape cartridge and the takeup reel to the rotary heads.

Abstract: Recombinant host cells are obtained that comprise (A) a heterologous, polypeptide-encoding polynucleotide segment, stably integrated into a chromosome, which is under transcriptional control of an endogenous promoter and (B) a mutation that effects increased expression of the heterologous segment, resulting in enhanced production by the host cells of each polypeptide encoded by that segment, relative to production of each polypeptide by the host cells in the absence of the mutation. The increased expression thus achieved is retained in the absence of conditions that select for cells displaying such increased expression. When the integrated segment comprises, for example, ethanol-production genes from an efficient ethanol producer like Zymomonas mobilis, recombinant Escherichia coli and other enteric bacterial cells within the present invention are capable of converting a wide range of biomass-derived sugars efficiently to ethanol.

Abstract: The automated library system stores and retrieves media cartridges for an associated plurality of media drives. Within this system, a virtual robot is implemented to create multiple virtual media libraries within the single automated cartridge library system. This capability enables the use of a plurality of types of media within the single automated cartridge library and a corresponding plurality of drive elements within the library. Thus, each drive element has associated therewith a number of object storage locations within the library which contain media of a form and content that matches the drive element. The automated cartridge library system manages the correspondence between object storage location, media type, designated drive element in an automated manner such that the single library appears to the user as multiple independent libraries. This enables the user to transition to another media on an incremental basis, since a single drive element can be added to the library and associated media added as needed without displacing the embedded base of installed robotic media handling equipment or requiring significant modification to this equipment. Furthermore, the automated library system provides a media management capability to define media subsets media elements which have consistent mechanical and electrical characteristics, can vary in data management attributes.

Abstract: In a housing, there is formed, in series, a first end cavity, a first cylinder cavity, a pressure cavity, a second cylinder cavity and a second end cavity. The cavities are separated by walls which include orifices. Two identical valve members are located in the housing. The first valve member has a piston and a valve plug in the first end cavity and a valve plug in the pressure cavity. The second valve member has a piston and a valve plug in the second end cavity and a valve plug in the pressure cavity. Pressure in the pressure cavity acts on the confronting ends of the two valve members. A two position control rod, in a first position, connects pressure to the piston in the first end chamber and connects the second end chamber to return. The piston has a larger area than the second end of the valve member, creating a force differential which moves the first valve member endwise inwardly. Pressure acting on the second end of the second valve member moves it endwise outwardly. The same control rod, in it's second position, connects the second piston with pressure and the first piston with return. Pressure acting on the second end of the first valve member moves it endwise outwardly. Pressure acting on the second piston moves the second valve member endwise inwardly. Such movement of the valve members moves the valve plugs to open and close orifices in the separator walls, to switch pressure and return between two paths leading from the valve assembly. <IMAGE>
