Title: Flash tube reflector with arc guide
Inventor: THOMAS BRADLEY SCOTT
IPC: F21V7/00
Filed: 1999-02-26
Granted: 2002-07-30
Abstract: A combined reflector and arc guide for use with a xenon flash tube comprises a reflector structure having a reflecting surface that is adapted to be placed in a predetermined orientation with respect to the flash tube. An electrically conductive arc guide is carried by, and is preferably integral with, the reflector structure for controlling the arc in the flash tube. The arc guide comprises an elongated ridge that projects outwardly from the reflecting surface of the reflector structure, and extends in a direction substantially parallel to the longitudinal axis of the flash tube. An electrical terminal is carried by the reflector structure and has an electrical connection to the arc guide for allowing an electrical potential to be applied to the arc guide. The reflector structure is preferably made of an electrically conductive plastic material, thereby providing continuity between the electrical terminal and the arc guide without the need for a separate conductor. An area of modified reflectivity, preferably in the form of a plurality of grooves, may be provided in the reflective surface of the reflector structure to spread out the intensity peak of the flash tube. The disclosed reflector is simple and inexpensive to manufacture, and is suited for use in automated hematology systems in which a pulse of light from the flash tube causes dyed blood cell layers in a capillary tube to fluoresce so that a complete blood count can be obtained by optical imaging techniques while the blood sample is being rotated in a centrifuge.

Title: Protein stabilized pharmacologically active agents, methods for the preparation thereof and methods for the use thereof
Inventor: LOUIE LESLIE
IPC: A61K47/42
Filed: 1997-09-24
Granted: 2007-05-08
Abstract: In accordance with the present invention, there are provided compositions and methods useful for the in vivo delivery of substantially water-insoluble pharmacologically active agents (such as the anticancer drug paclitaxel) in which the pharmacologically active agent is delivered in the form of suspended particles coated with protein (which acts as a stabilizing agent). In particular, protein and pharmacologically active agent in a biocompatible dispersing medium are subjected to high shear, in the absence of any conventional surfactants, and also in the absence of any polymeric core material for the particles. The procedure yields particles with a diameter of less than about 1 micron. The use of specific composition and preparation conditions (e.g., addition of a polar solvent to the organic phase), and careful selection of the proper organic phase and phase fraction, enables the reproducible production of unusually small nanoparticles of less than 200 nm diameter, which can be sterile-filtered. The particulate system produced according to the invention can be converted into a redispersible dry power comprising nanoparticles of water-insoluble drug coated with a protein, and free protein to which molecules of the pharmacological agent are bound. This results in a unique delivery system, in which part of the pharmacologically active agent is readily bioavailable (in the form of molecules bound to the protein), and part of the agent is present within particles without any polymeric matrix therein.

Abstract: A high pressure fluid seal assembly is shown and described. The seal assembly includes a seal carrier having a bore through which a reciprocating pump plunger may pass, the seal carrier having a first annular groove concentric with the bore, and carrying an annular seal. The seal carrier further includes an integral annular guidance bearing positioned in a second annular groove of the seal carrier, the second annular groove and guidance bearing contained therein being axially spaced from the first annular groove and seal contained therein. An inner diameter of the guidance bearing is smaller than an inner diameter of the seal carrier in a region between the seal and the guidance bearing. The seal is therefore supported directly by the seal carrier, although the seal carrier is spaced from the reciprocating plunger by the guidance bearing. Frictional heating in the region of the seal is therefore reduced, thereby increasing the life of the seal. Materials for the plunger, seal and guidance bearing are selected to minimize friction between the plunger and seal and between the plunger and guidance bearing. Furthermore, the seal assembly is manufactured by pressing the guidance bearing into the seal carrier, and then machining the bore in the guidance bearing and in the seal carrier in the same setup, thereby improving the alignment of the elements and simplifying manufacturing.
