Title: Dispenser package.
Inventor: GOULD JEROME
IPC: B65G59/10
Filed: 1983-01-10
Abstract: A dispenser package for stacks of nested tapered cups that serves as a shipping container, and as an apparatus for dispensing cups. The problem associated with cup dispensers, is that it is not always practicable to mount the dispenser in every desired location. The present system provides a plurality of containers containing the cups stackable upon one another to be used in a variety of locations, and positions. The dispenser package (11) holds a stack of nested tapered disposable cups (25) for dispensing them individually. The dispenser package (11) has a generally circular opening (18, 118) in the top wall (12, 112) through which the bottoms of the tapered cups protrude surrounded by a series of flexible tabs or yieldable segments (23, 119) around the periphery allowing a cup to be pulled through the opening, but which function to restrain the cup immediately below. Slits or knife cuts (26, 122) in the top wall (12, 112) of the dispenser package (11) extend from the opening (18, 118) in the top wall (12, 112) to each of the sidewalls (14, 15, 16, 17) at the mid point of each sidewall to permit loading a stack of cups (25) through the top opening (18, 118) of the dispenser package (11) without tearing of the top wall (12, 112). An opening (19) may be provided in the bottom wall of each package with radial slits (21) extending outward a distance sufficient to permit stacking of the individual packages (11) into a compact, multiple unit bundle of package (10) for shipping and display.

Patent EP-0292487-A4 (EP)
IPC: H04J1/02
Filed: 1987-01-27
Abstract: Système de transmission à spectre élargi, dans lequel plusieurs signaux à spectre élargi sont multiplexés par division des fréquences en décalant d'une fraction de l'espacement de lignes spectrales des signaux les fréquences centrales ou les fréquences des porteuses des signaux à spectre élargi. Ceux-ci sont produits en modulant une porteuse avec un signal codé de pseudo-bruit (PN). Lorsque les signaux arrivent à un récepteur, le démultiplexage est effectué en mélangeant (42) le signal multiplexé reçu avec plusieurs fréquences (43) d'oscillateurs locaux, lesdites fréquences étant décalées les unes des autres de la même façon que les fréquences centrales ou les fréquences des porteuses des signaux multiplexés à spectre élargi. Les signaux mélangés sont ensuite à nouveau mélangés (45) avec les signaux codés de PN produits (47) correspondants à ceux utilisés pour produire les signaux multiplexés à spectre élargi. La durée de chaque signal codé de PN produits est ensuite avancée ou retardée en réponse au signal de commande de la durée respectif (48) produit par l'unité de commande respective (46). Après mélange (45), on fait passer les signaux à travers des filtres à bande étroite respectifs (49), afin de sélectionner les signaux de bande de base devant ensuite alimenter les unités de commandes respectives (46) permettant la production des signaux de commande (48) des durées. Lorsqu'elle est appliquée à un système de localisation d'un véhicule en déplacement, la présente invention utilise plusieurs récepteurs espacés.

Title: Biodegradable superparamagnetic materials used in clinical applications.
Inventor: GROMAN ERNEST V
IPC: C08J9/14
Filed: 1987-07-01
Abstract: This invention relates to materials exhibiting certain magnetic and biological properties which make them uniquely suitable for use as magnetic resonance imaging (MRI) agents to enhance MR images of animal organs and tissues. More particularly, the invention relates to the in vivo use of biologically degradable and metabolizable superparamagnetic metal oxides as MR contrast agents. Depending on their preparation, these metal oxides are in the form of superparamagnetic particle dispersoids or superparamagnetic fluids where the suspending medium is a physiologically-acceptable carrier, and may be uncoated or surrounded by a polymeric coating to which biological molecules can be attached. These materials are administered to animals, including humans, by a variety of routes and the metal oxides therein collect in specific target organs to be imaged; in the case of coated particles, the biological molecules can be chosen to target specific organs or tissues. The biodistribution of the metal oxides in target organs or tissues results in a more detailed image of such organs or tissues because the metal oxides, due to their superparamagnetic properties, exert profound effects on the hydrogen nuclei responsible for the MR image. In addition, the dispersoids and fluids are quite stable and, in the case of the fluids, can even be subjected to autoclaving without impairing their utility. Furthermore, the materials are biodegradable and, in the case of iron oxide compounds, can eventually be incorporated into the subject's hemoglobin, making them useful in treating anemia. Thus, the materials are well-suited for in vivo use.

Title: A file system for a plurality of storage classes
IPC: G06F12/08
Filed: 1989-04-19
Abstract: A file system for managing data files for access by a plurality of users of a data processing system that includes internal storage for buffering, external storage, and a file user interface by which the plurality of users request access to data files. A first level, coupled to the file user interface in the internal storage allocates the internal storage for temporary storage of data to be accessed by the plurality of users, and generates requests for transactions with external storage in support of such allocations. A second level is coupled to the first level and the external storage and responds to the request for transactions with the external storage for managing the transactions for storage of data to, and retrieval of data from, the external storage. The second level defines a plurality of physical storage classes which are characterized by pre-specified parameters that allocate data files subject of transactions to locations in external memory. In response to requests for transactions, the second level identifies one of the plurality of storage classes assigned to the data file subject of the transaction and carries out the transaction with the appropriate locations in external memory. At least one of the plurality of storage classes provides for utilization of a plurality of access paths in parallel for transactions involving data files assigned to such storage class. Further, at least one parameter pre-specified for storage classes identifies a level of reliability desired for the subject data files.
