Title: Site-selective reinforced catheter and methods of manufacturing and using the reinforced catheter
Inventor: MOOREHEAD H ROBERT
IPC: A61M25/00
Filed: 1992-02-27
Abstract: ABSTRACT OF THE INVENTION    The present invention is directed to novel methods and apparatus for a reinforced catheter which can be employed to withstand the damaging stresses experienced by catheters implanted in bodily tissues, particularly catheters implanted in the compressed area between the clavicle and first rib of a patient.  The reinforced catheter is made from a nonmetallic inner tubular sleeve comprised wholly of a compliant material that is inserted selectively within a catheter.    The reinforced catheter can be manufactured by immersing a portion of a catheter in freon which causes the immersed portion to swell.  Thereafter, a reinforcing sleeve, having an outer diameter greater than the inner diameter of the pre-immersed catheter, but having an outer diameter smaller than the inner diameter of the immersed catheter, can be advanced site-selectively to a position within the catheter.  Finally, the portions of the exposed catheter are allowed to return to their normal size around the inserted reinforcing sleeve.    Alternatively,   the   reinforced   catheter   can   be manufactured  by  advancing  a  reinforcing  sleeve  site-selectively to a position within the catheter by introducing pressurized gas within the catheter.   As the reinforcing sleeve is moved to the, opening of the catheter, a hollow rod, connected to an air pump, forces air ahead of and around the reinforcing sleeve, increasing the diameter of the catheter surrounding the reinforcing sleeve so that the reinforcing sleeve may be advanced.  After the reinforcing sleeve is in position, the rod is removed and the catheter returns to its normal position surrounding the reinforcing sleeve.

Abstract: Photoplethysmographics Using Phase-Division Multiplexing Abstract First and second carrier signals, distinguishable by phase, are respectively applied to infrared and red energy emitters.  A detector receives the sum of the energy after modulation at the infrared and red wavelengths.  The sig-nal received by the detector is then demultiplexed into its original first and second components, thereby allowing determining of both the infrared and red modulation compo-nents.  The first and second carrier signals may comprise time-varying periodic signals with identical frequency and frequency spectra, such as a pair of sine waves which are indistinguishable except by phase and amplitude. A 90° phase difference is preferred, but any phase other than 0 or an integer multiple of 180° is workable.  A carrier frequency which avoids excessive interference from ambient light is preferred.

Title: Preterminated fiber optic cable
Inventor: NILSSON RICHARD C
IPC: H02G15/08
Filed: 1992-04-03
Abstract: ABSTRACT OF THE DISCLOSURE    A preterminated optical fiber cable has a main trunk cable comprising a plurality of optical fibers disposed therein and multiple drop cables spliced to the trunk cable at various branch points, the preterminated fiber optic cable being completely assembled at the time of manufacture and is easily installed thereafter.  At each branch point an optical fiber cable splice closure is utilized for protecting the optical fibers and splices from moisture and mechanical damage, providing a strong anchoring point for the optical fiber drop cable, and insuring that the minimum fiber bend radius is not violated.  The splice closure is cylindrical in shape and has a cavity providing room for the splices and for excess optical fiber storage.  Because the splice closure is relatively small (an outer diameter of no greater than 4 inches and a length of no greater than 7 inches), the preterminated fiber optic cable, after manufacture, may be wound in reels for installment without incurring cable or fiber damage and, further, may be deployed within standard PVC piping having a 4 inch inner diameter.  The preterminated fiber optic cable may also be preconnectorized.

Title: Methods for treating diseases using oxidized lipoproteins
Inventor: FOSSEL ERIC T
IPC: A61K31/02
Filed: 1990-10-04
Abstract: The present invention relates to treating disease states in a living patient using oxidized lipoproteins, preferably low density peroxidized lipoproteins. Methods and apparatus are provided for preparing the oxidized lipoproteins. It has been discovered that diseased cells, characterized by an increased number of lipoprotein receptors or an enhanced ability to take up lipoproteins are more susceptible than healthy cells to the cytotoxic effect of oxidized lipoproteins. Oxidized lipoproteins are used to treat disease states such as cancer, malaria and viral infections such as acquired immunodeficiency syndrome (AIDS). Proton and carbon-13 NMR  spectroscopy is used to measure the degree and effect of treatment with oxidized lipoproteins.

Abstract: ABSTRACT                   FUSION PROTEINS            Relatively inactive fusion proteins are activatable by enzymes of the clotting cascade to have fibrinolytic and/or clot  formation  inhibition activity.    For example,  a fusion protein comprising two hirudin or streptokinase molecules, linked by a cleavable linkage sequence,  may be cleaved to yield anti-thrombotic hirudin or fibrinolytic streptokinase by thrombin or Factor Xa.  Fibrinolytic or clot formation inhibition activity is therefore directed to the site of clot formation.

Title: Spark duration control for a capacitor discharge ignition system
Inventor: MCCOY STEVEN R
IPC: F02P9/00
Filed: 1991-11-01
Abstract: Abstract of the Disclosure Spark Duration Control for a Capacitor Discharge Ignition System An apparatus is provided for controlling ignition in an internal combustion engine having N cylinders and a capacitor discharge ignition system. The capacitor discharge system includes an ignition capacitor (18) which is maintained at a predetermined electrical potential by a charging circuit (14).  N transformers (24a-f) are provided, each having a primary coil (26a-f) and a secondary coil (28a-f). The primary coils (26a-f) include first and second terminals (30a-f, 32a-f) and the secondary coils (28a-f) are electrically connected in parallel with the spark gap (22a-f) in an associated one of the cylinders.  Selector switches (34a-f) are connected between the ignition capacitor (18) and an associated one of the primary first terminals (30a-f).  The selector switches (34a-f) are normally biased open and are adapted to close in response to receiving cylinder select signals.  The cylinder select signals are produced in response to a desired ignition sequence and for a period of time corresponding to a desired spark duration in an associated cylinder.  A modulation switch (52) is connected between the primary coil second terminals (32a-f) and a source of low electrical potential.  Control circuitry is provided for operating the modulation switch (52) while a selector switch (34a-f) is closed such that the current flowing in an associated primary coil (28a-f) initially rises to a first threshold sufficient to cause a spark to arc an associated spark gap.  Thereafter the current is modulated between the first threshold and a second threshold lower than the first threshold to maintain the spark.  The spark is maintained in this manner until the associated selector switch (34a-f) is opened.
