Title: Preparation of rhenium phosphonate therapeutic agents
Inventor: PIPES DAVID W
IPC: A61P35/00
Filed: 1990-03-12
Abstract: ABSTRACT The process of the present invention includes prepar-ing a first aqueous solution of rhenium in the form of rad-ioactive perrhenate, wherein the concentration of rhenium in said solution is within the range of about 5 x 10-6 M to about 2 x 10-3 M, and then reducing and complexing the rad-ioactive perrhenate by mixing a second solution or lyophil-ized solid with the first solution. The second solution or lyophilized solid comprises a ligand which complexes with the radioactive perrhenate and a reductant wherein the re-ductant is present in the second solution at a concentra-tion in the range of about 0.005 M to about 0.020 M and the ligand is present in the second solution at a concentration in the range of about 0.01 M and about 0.15 M. The pH of the resultant solution is within the range of about 1.5 to about 5.5.

Filed: 1992-07-31
Abstract: A process for creating segments out of an arbitrary string of handwritten alphanumeric script is described, in which the contours of the image are defined by the path a ball or pointer follows when allowed to roll from the top and bottom of an image, down or up either side. From the contours, the initial image cut points are determined. The pointer is provided with a capability to measure ink density in the nearby pixels. A grey scale threshold control is provided which operates in conjunction with the pointer as it rolls or moves, to define ink density above the threshold as a white pixel wherein no image content is present; and ink density below the threshold as a black pixel wherein image content is present.

Abstract: A generally rectangular shelter with a readily assembled frame mounted on a base and covered with a flexible sheet material secured to the frame and base is provided.  The base is normally of wood and is placed on the ground or other planar surface   Spaced at a desirable distance along each side of the base are pivotal and adjustable supports fixed to the base.  To the supports are connected a series of assembled frame ribs transverse to the length of shelter.  The frame ribs are normally assembled in an arcuate shape from several pieces of tubing coupled together by a special coupler.  The tubes are adapted to receive other tubes by having pin receiving tabs welded to them in appropriate places.  Purlins or other spacers are connected between the frame ribs so that all the frame ribs may be drawn up from an assembled horizontal position to an upright position as a unit.  Cross bracing is placed between the frame ribs as required and a cover formed of several panels of flexible sheet material is then placed over the erected frame to form a basic shelter. The several panels are generally insulated fabric and are secured to the frame ribs by having all edges carrying a single continuous draw cord.  The panels overlap with the overlapping side edges carrying the draw cord partially wrapping each panel side edge around an adjacent frame rib covered by each panel in a sealing and securing relationship when the panels are tightened by the pivotal and adjustable supports.  The ends of the panels include grommets that receive fasteners that are imbedded in the base for total securement of the panels.  Front and rear basically semi-circular panels are each secured to an end rib and the base in a similar manner and are placed against front and rear end wall posts of front and rear end walls which are assembled before or after pivoting and are connected to the base and an end frame rib.  The total cover or the basic shelter cover is tightened by vertically adjusting all the pivotal and adjustable supports fastened to the base each carrying a bottom end of a frame rib.

Inventor: SKIBO MICHAEL D
IPC: C22C32/00
Filed: 1991-07-12
Abstract: A cast composite material is made from particles and a matrix alloy preselected composition that is difficult to wet to the particles. A wetting alloy having a composition that readily wets the particles is first mixed with the particles under conditions that wet the wetting alloy to the particles. The wetting alloy is selected so that it has no alloying elements in excess of that in the preselected matrix alloy, and preferably with wettability inhibiting elements reduced. After wetting and mixing have been achieved, the remaining alloying ingredients are added to the melt to adjust the matrix to the desired composition. The approach is applicable to cast composite materials containing both reactive and nonreactive particles. Also described is a cast composite material formed from about 5 to about 35 volume percent of particulate reinforcement, e.g. silicon carbide, embedded in an aluminum alloy matrix having from about 8.5 to about 12.6 weight percent silicon. This silicon-containing composite material is particularly well suited for use as a foundry alloy for remelting purposes.

Title: Asynchronous switching node and routing logic means for a switching element used therein
Inventor: PAUWELS BART J G
IPC: H04L12/56
Filed: 1993-11-17
Abstract: Abstract The routing logic means (RL) first selects, based on a route reference number included in the internal routing label (RCA,TCP) and associated to a cell to be routed by it, at least one set including a number of routing groups each of which itself includes a number of outlets. The routing logic means then secondly selects one routing group per selected set of routing groups and finally also selects from each such selected routing group an outlet to which a copy of the above mentioned cell is transferred.           In this way a distribution of (copies of) cells to arbitrarily chosen output ports of a switching node including such a routing logic means can be effected both for point-to-point as for multicast connections.           In a particular embodiment, the first selection is done via a routing memory (RM) whose memory locations (MSK) are addressed via the route reference number. The content of this memory location is then interpreted by a selection mean (SEL) which identifies the routing groups included in the set and performs the second selection randomly selecting any one of the groups included in the set.
