Title: Detection of antibodies in body fluids for diagnostic testing
Inventor: THIEME THOMAS R
IPC: G01N33/548
Filed: 1990-01-25
Abstract: A method for detection for screening and diagnostic purposes of antibodies in a body fluid by means of an antibody-binding protein covalently bound to a porous matrix trapped within a transparent column. A test fluid containing antibody is contacted with the protein-bound matrix whereby the protein reacts with to immobilize any antibody present in the test fluid. A biotinylated antigen of interest is contacted with the immobilized antibody whereby the biotinylated antigen binds to the immobilized antibody. Avidin covalently linked to an enzyme is contacted with the immobilized biotinylated antigen-immobilized antibody-protein bound matrix complex whereby the enzyme-labelled avidin binds to the immobilized complex. This immobilized complex is contacted with a substrate solution wherein the enzyme linked to avidin catalyzes a reaction of the substrate and produces a detectable reaction product which correlates to the presence of the antibody to be detected.

Title: Global positioning system receiver digital processing technique
Inventor: LORENZ ROBERT G
IPC: G01S1/00
Filed: 1992-02-12
Abstract: A Global Positioning System (GPS) commercial receiver is provided with a digital processor that can utilize to advantage P-code modulated L1 and L2 satellite signals which have been modulated with an unknown security code. Integration of the L1 and L2 signals, after demodulation by locally generated carrier and P-code signals, is repetitively accomplished over a duration that is estimated to be the period of the modulation code. The C/A-code L1 signal, which is not modulated with the unknown security code, is also used in locking the locally generated carrier and P-code generators in phase with the received L1 and L2 satellite signals. A interpolative technique is used for adjusting the phase of the locally generated carriers and code in increments much smaller than the period clock sources. Those locked phases can then be utilized to determine position, distance, time, etc., as is done in GPS receivers not utilizing the anti-spoofed signals but with increased accuracy and resolution. A novel structure of the GPS receiver radio frequency and intermediate frequency sections, having a specific combination of demodulating frequencies, is also disclosed.

IPC: B23B51/00
Filed: 1992-02-20
Abstract: In a combination tool bit and tool bit holder or chuck, rotary entrainment members (6, 7) extending over different circular arcs are formed in the tool bit holder for transmitting torque to the tool bit shank (8). Corresponding rotary entrainment grooves (9, 10), also extending over different circular arcs, are formed in the tool bit shank (8). Locking members (4) axially retain .the tool bit in the holder. The locking members (4) can be displaced radially into or out of the recesses (11, 12) in the tool bit shank (8). The recesses (11, 12) are laterally closed. Due to the different configurations of the rotary entrainment members (6, 7) and the corresponding grooves (9, 10) it is possible to transmit higher torques while avoiding detrimental cross-sectional weakening of the tool bit shank (8).
