Abstract: A biochemical procedure for identification and characterization of cells in a biopsy or sample of a body fluid. The procedure is based on the isolation and analysis of the components of a specific subcellular protein fraction referred to as the "nuclear matrix". The nuclear matrix includes proteins and nuclear matrix associated DNA specific to different cell types. These proteins and nucleic acids are altered or new ones expressed as a result of viral infection, genetic defects or malignancy. The method can be used to determine cell type, i.e. epidermal, neuronal; tissue of origin, i.e, breast tissue, liver tissue; and degree of abnormality. The procedure can also be used to make antibodies and hybridization probes to detect cell or tissue specific antigens and nuclear matrix associated nucleic acids in cellular material and body fluids.

Title: Enzyme amplification method and compositions for its implementation
Inventor: GIESE ROGER W
IPC: C12Q1/68
Filed: 1987-04-14
Granted: 1992-04-21
Abstract: ABSTRACT     A method for amplifying enzyme activity is disclosed. Enzyme amplifica-tion is achieved by covalently bonding enzyme to a supporting material via a molecular chain which is a substrate for the enzyme, then introducing a small amount of enzyme in the free state to this system, causing release of a large amount of bound enzyme. In an alternative embodiment, complementary enzymatically inactive fragments of an active enzyme, which fragments can recombine to form active enzyme, are covalently attached to separate support materials by a molecular chain material which is a substrate for the active enzyme, and these two fragment-support conjugates are connected in series. Upon application of free enzyme or free complementary enzyme to one of these fragment-support conjugates, followed by application of the resulting product mixture to the second fragment-support conjugate, a large amount of free enzyme is ultimately produced. In a second alternative embodiment, two different active enzymes are each attached to separate supporting materials by different leashes, in which the leash for the first enzyme only is cleaved in the system by the second enzyme, and the leash for the second enzyme only is cleaved in the system by the first enzyme. These two materials are connected in series, and upon application of the second enzyme to the first enzyme-support conjugate, followed by application of the released first enzyme to the second enzyme-support conjugate material, ultimately a large amount of released active second enzyme is produced. Also disclosed are molecular conjugates of enzyme material on supports, required for the enzyme amplification. As a prototype enzyme amplification system the S-peptide and S-protein fragments of ribonuclease S (RNase S) have been immobilized onto separate. Sepharose gels via a polycytidylic acid (poly C) substrate leash. Each of these gels releases its RNase fragment when treated with the complementary enzyme fragment or with RNase A.  Also the released fragments recombine to give RNase S activity. Thus this system provides more enzymatic activity from the system than is applied. A 100 pg sample of Nase is amplified by 1.9 x 104 in 20 hours to yield activity equivalent to 1.9 µg of RNase, by applying it to the S-peptide gel followed by combination of the released S-peptide with excess S-protein. Also, application of 1 ng of RNase A to a three-stage amplification system in which each stage consists of a pair of S-peptide and S-protein gels produced cumulative amplifications of 4.9, 52, and 25x after each of the stages, respectively. Only 1-2 mg amounts of each gel are used per stage in these experiments, reflecting the significant production of RNase S activity.

Title: Probe for the determination of gas concentration in molten metal
Inventor: DUBE GHYSLAIN
IPC: G01N33/20
Filed: 1987-05-28
Granted: 1990-11-13
Abstract: The invention provides a new immersion head probe for use in apparatus for the determination of the concentration of gas dissolved in a molten metal. Such determinations are needed to facilitate removal of the gas, which can cause bubbles in the solidified metal and subsequent processing difficulties. The apparatus circulates an inert carrier gas through the probe in gas exchange contact with the molten metal to entrain dissolved gas until an equilibrium mixture is obtained; the concentration of the dissolved gas in the mixture then is representative of its concentration in the molten metal. The head consists of a monolithic or integral body of a porous gas-permeable material of sufficient mechanical strength at the temperature of the molten metal and of sufficient porosity, pore size and permeability to permit the necessary gas diffusion in a reasonable period of time. The body of the probe preferably is thin in one direction to minimize the path length for the gas to diffuse therein, and is provided with a carrier gas inlet and outlet suitably spaced apart to ensure that the gas diffuses throughout the body. If the test is to be carried out in a stationary body of molten metal, the probe may be vibrated or the metal may be stirred to increase the probe/metal contact, both decreasing the time required for the gas mixture to reach sufficient equilibrium.

Title: Fast tuning control for a television system
Inventor: WRIGHT WORTLEY A JR
IPC: H04N7/16
Filed: 1987-06-02
Granted: 1991-01-08
Abstract: FAST TUNING CONTROL FOR A TELEVISION SYSTEM          Abstract of the Disclosure A fast tuning subsystem includes a tuner for selecting a channel, with a voltage controlled oscillator having a control input for determining the channel frequency the tuner selectively receives.  A predictor supplies a selected predicted voltage signal from memory to the control input of the oscillator to slew the channel frequency at a rapid slew rate to the frequency corresponding to the selected predicted voltage signal.  An error detector generates a tuning error signal indicative of the tuning error of the tuner off the frequency for the selected channel.  The tuning error signal is combined with the selected predicted voltage signal to provide a control signal for adjusting the channel frequency to reduce the tuning error.  The subsystem also similarly controls the amplitude of the received channel.  The tuning subsystem automatically and from time to time changes the signals stored in the memory for respective channels to signals corresponding to the control signals applied after long term feedback.  The feedback provides successively a correction mode and a station-keeping mode.  The correction mode provides correction of any error in tuning of an acquired channel fast enough that the correction is substantially imperceptible to the eye and any residual error is substantially imperceptible to the eye.  The station keeping mode operates slowly enough to filter out noise and spurious signals and maintain any residual error below a predetermined limit over long periods of time.

Abstract: ABSTRACT OF THE DISCLOSURE    A rotating member such as a sprocket to be coupled with a shaft is formed with a fitting bore which extends on the center axis and opens at at least one of its axial end portions.  The rotating member is arranged in and rotatably held by a case such that its fitting bore opens toward the outside of the case.  The shaft is inserted into and coupled with the fitting bore held in the case such that it can rotate integrally with the rotating member.  This rotating member is formed with an air communication portion for providing communication between the inside and outside of the fitting bore and equipped with a valve for opening or closing the air communication portion.  The valve may be opened in response to the rise or drop in the internal pressure of the fitting bore, by the pressure of the shaft or by a centrifugal force.  With the valve being closed, lubrication oil in the case is prevented from leaking.  When the valve is opened, on the other hand, the air in the fitting bore is released, or the atmospheric air is introduced into the fitting bore. As a result, the insertion or extraction of the shaft is prevented from being obstructed even with fluctuations in the internal pressure of the fitting bore.

Title: Optical reading of quantum well device
Inventor: BAR-JOSEPH ISRAEL
IPC: G02F1/015
Filed: 1987-12-04
Granted: 1991-01-08
Abstract: Abstract:     Optical apparatus is disclosed wherein narrow line width light from a source is directed through the substrate of a semiconductor structure and reflected from the gate electrode of a field effect transistor element fabricated on the surface of the semiconductor structure.  A quantum well layer serves as the current channel for the field effect transistor, and charge carriers from a doped semiconductor layer provide high mobility carriers in the quantum well layer.  Changes in the potential between the gate and source electrodes of the field effect transistor causes the normal pinchoff of carriers in the quantum well layer thereby causing changes in the absorption characteristic presented by the quantum well layer. By directing light from the source at the gate electrode through the substrate of the semiconductor structure, a photodetector can be positioned so as to detect a change in light which has passed twice through the quantum well layer, thereby detecting a change in the electrical state of the field effect transistor.
