Title: Radar tomography
Inventor: MURPHY QUENTIN M
IPC: A61B5/05
Filed: 1990-04-18
Abstract: ABSTRACT OF THE DISCLOSURE            A radar tomography method and apparatus generates a plurality of radar pulses in a transmitter and projects them with an antenna toward a patient.  Radar pulses reflected from the patient are picked up by the antenna and conducted to a receiver.  Predetermined radar pulses are selected from among the received pulses by a timer/gate circuit connected to the receiver.  The selected radar pulses correspond to a predetermined area of interest within the patient.  A representation of the predetermined area within the patient may be displayed with known display apparatus.  The antenna may also be moved relative to the patient, in order to produce three-dimensional information.  Synchronizing the transmitter, the timer/gate device, and the movement of the antenna may be effected with a synch processor, and a matrix filter may be used to focus the emitted radar pulses and to reduce noise in the return radar pulses.

Abstract: A conveying member is used in a conveying system for a recording medium in an ink recording apparatus that effects recording by the use of ink. The conveying member bears against the surface of the recording medium after printing and is rotatable.  The peripheral surface of the  member is of a shape in which it continuously bears against the recording medium, and the region of the member which contacts with the printing surface of the recording medium makes the bonding force with respect to the ink small relative to the bonding force between the recording medium and the ink and the cohesive force of the ink itself, thereby preventing the adherence of the ink to the continuous peripheral surface.

Filed: 1991-05-17
Abstract: HIGH PRESSURE PISTON PUMP FOR FLUENT MATERIALS            ABSTRACT A pump assembly especially adapted for pumping viscous and/or abrasive materials is comprised of a pair of opposed single acting piston pumps operated alternately by an interposed reciprocal actuator, and a static chamber interposed between each pump and the actuator; each pump comprising a pumping chamber having aligned inlet and outlet check valves in its peripheral wall and defining a straight line path of fluid flow diametrically through the chamber, a piston having its periphery spaced from the peripheral wall of the pumping chamber and having a relatively short stroke to maintain the straight line path of fluid flow through the chamber, and an annular seal extending from the peripheral wall of the pumping chamber toward the piston and bridging the gap between the periphery of the piston and the peripheral wall of the pumping chamber, the piston having sealed engagement with the seal throughout its reciprocal path of movement; the static chambers isolating the two pumps and the actuator from one another so that fluid leakage from any of them will not adversely affect the others.  The pump assembly facilitates pressurized or forced feeding of fluent material to the two pumps, and therefore, the pumping of extremely viscous fluent materials, and utilization of the assembly in a wide variety of systems applications.

Title: Detection of delta-bilirubin
Inventor: WU TAI-WING
IPC: C07K16/18
Filed: 1991-06-10
Abstract: ABSTRACT           A novel  method  for the  determination of authentic delta-bilirubin is provided.   This method utilizes a novel monoclonal antibody produced using hybridoma technology and directed specifically against delta-bilirubin rather than against bilirubin that is synthetically or chemically linked to albumin.   The antibody is able to distinguish between delta-bilirubin and other forms of bilirubin by recognition of the specific covalent linkage present between bilirubin and albumin  in delta-bilirubin.   Detection of delta-bilirubin is important in the diagnosis of various hepatobiliary disorders and in the early prognosis of liver transplant patients.  As a result, an immunoassay kit for delta-bilirubin detection is also provided.

Inventor: JACKSON ARTHUR
IPC: C07B61/00
Filed: 1990-04-04
Abstract: A potassium salt useful in the production of certain N-substituted alkyl or arylalkyl thionitroethenamines is produced by the reaction of the dipotassium salt of a 2-nitrodithio aliphatic acid such as 2-nitrodithio acetic acid with branched chain primary alkylamines, secondary alkylamines, arylalkylamines or heterocyclic alkylamines such as dimethylamine, pinacolylamine, benzylamine or piperonylamine, thereby converting one only of the KS-groups to an alkylamine group. The resulting monopotassium salt may be alkylated or arylalkylated to produce an N-substituted alkyl or arylalkyl thionitroethenamine. This compound may be reacted with a suitable amine to produce compounds containing the pharmaceutically active grouping -NHC( = CHNO2)NHX, wherein X represents an alkyl, arylalkyl or heterocyclic alkyl group.

Abstract: A beam (12) of continuous wave ultraviolet light having a wavelength that is absorbed by an organic solid (20) is focused to a spot (18) on a surface of the organic solid (20).  Relative motion is imparted between the beam (12) and organic solid (20) at a rate that defines, together with a dimension of the spot (18), an effective pulse width.  Within prescribed ranges of the wavelength, power density and effective pulse width, a new cutting regime was discovered whereby organic solids can be cut at rates and with a quality of cuts previously requiring pulsed ultraviolet laser sources.

Title: Muffler and method for fabricating the same
Inventor: PRESLICKA A J
IPC: F01N1/08
Filed: 1991-11-05
Abstract: A vehicular exhaust system muffler including a reversing unit sub-assembly having spaced apart internal panels; and flow tubes that extend between the internal panels and that have their ends mechanically locked within flanged apertures in the internal panels. A sheet metal wrapper is formed around the peripheries of the panels so that the wrapper is in contact with but is metallurgically unbonded to the panels and so that ends of the flow tubes are adjacent to the side edges of the wrapper.      End cap sub-assemblies are assembled onto each end of the reversing unit sub-assembly and wrapper.      Each end cap sub-assembly includes an end panel having an aperture surrounded by a flange that projects from one side surface of the end panel, and an end tube that extends through the end panel flanged aperture. One end of each end tube has an outer diameter selected such that the one end may be loosely, telescopically and overlappingly fitted within the adjacent end of the adjacent flow tube.      The overlapped ends of the end tubes and the flow tubes are mechanically locked together by a circumferential skewed bead formed in the overlapped ends, where the plane of the skewed bead is at an angle less than ninety degrees with respect to the central longitudinal axis of the overlapped ends.      This mechanical locking maintains the relative axial positions of the overlapped ends and resists relative movement between the overlapped ends and between the internal panels and the wrapper due to the application of torsional and axial forces that the tubes experience during the assembly of the muffler. The end tubes are also mechanically locked within the end panel apertures. This mechanical locking includes a continuous, circumferential bead that is formed in the part of the end tube adjacent to side surface of the end panel opposite its flanged aperture and whose plane is at an angle of ninety degrees with respect to the longitudinal axis of the end tube; and a series of spaced apart, circumferential aligned elongated deformations in the overlapped portion of the end tube and the end panel flange, where the plane of these deformations is at an angle of ninety degrees with respect to the longitudinal axis of the end tube and where the major axes of the deformations are aligned with the plane of the deformations.
