Title: Reversible agglutination mediators
Inventor: TARNOWSKI THOMAS L
IPC: G01N33/553
Filed: 1988-05-18
Granted: 1993-09-07
Abstract: ABSTRACT OF THE DISCLOSURE    Compounds and methods are disclosed for reversibly aggregating particles suspended in a liquid medium.  The method comprises combining the liquid medium containing the particles with a polyionic polymer capable of aggregating the particles under conditions suitable for such aggregation.  Thereafter, the particles are contacted with a chemical reagent capable of cleaving the polyionic polymer under conditions sufficient to reverse the aggregation.  Optionally, magnetic particles are added to the liquid medium in the present method under conditions for non-specific binding and the medium including the aggregates is subjected to a magnetic field gradient to separate the aggregates from the medium.  The compounds of the present invention are polyions.  The aggregation of the particles is reversible upon contact with chemical agents which cleave at least some of the bonds within the polyionic polymer.

Granted: 1992-11-17
Abstract: ABSTRACT OF THE DISCLOSURE       An improved circuit for controlling the output power level of a radio frequency (RF) amplifier is disclosed.  The circuit samples the output of an RF amplifier.  The sample is amplitude modulated at a preselected modulation frequency and is passed to a detector.  In response to the amplitude modulated signal, the detector produces a signal whose amplitude is indicative of the RF amplifier's output power and whose frequency is the modulation frequency.  The amplitude of the signal produced by the detector is then compared to a reference amplitude and the difference (error signal) is used to control the gain of the RF amplifier.

Abstract: AN APPARATUS AND METHOD FOR PRODUCING A         DOUGH ROLL BY ROLLING UP A DOUGH PIECE          Abstract An apparatus and method is provided for  producing a dough roll by rolling  up  a  dough  piece . The  apparatus  comprises  a moving means(4)  that includes  a holding  roller (10)  and an endless belt supply device (8), and a rolling up mechanism (8) having upper and lower endless belt devices (14, 16). The belt of the  upper endless  belt device  moves rearwardly,  and the belt of  the lower  endless belt device  moves forwardly  at a speed higher than that of  the upper endless belt device. When a dough piece is fed  to the  apparatus the leading end begins to  be rolled  at the upstream ends  of the  upper and  lower endless belt devices while its  trailing end stays between the belt of  the endless  belt supply device  (8) and  the holding roller (10). Therefore, the leading end moves at a speed which equals  the difference  between the  speeds of  the upper  and lower endless belt devices while the trailing end moves at the same moving  speed as  that of  the belt  of the  endless belt supply device. By  controlling the  relation of  the speeds of these endless  belt devices  (8,  14,  16),  the dough  piece is stretched to have a  desired length  in the feeding direction.          When the dough piece is rolled,  a dough roll having a desired numb  er of layers can be produced.

Abstract: The present invention resides in the discovery of a new test means for detecting the presence of an ion in an aqueous test sample and determining its concentration. The test means comprises a porous carrier matrix substantially uniformly incorporated with a) a homogeneous hydrophobic mixture containing three principal ingredients: an ionophore capable of forming a complex with the ion, a hydrophobic vehicle, and a reporter substance capable of interacting with the complex of ionophore and ion to produce a detectable response; and b) a buffering substance capable of providing a pH in the range of from about 5 to 10. A test device comprises the test means affixed to one upper flat face of an elongated support member. In use, the aqueous test sample is contacted with the test means or device. The presence and/or concentration of the ion in the test sample is then determined by observing any detectable response produced. The test means and device of the present invention provide rapid results, sufficient detectable response forming in most instances in at least a few minutes.
