Title: Multiplex immunoassay system
Inventor: BLOCK MYRON J
IPC: C12Q1/68
Filed: 1990-07-20
Granted: 2001-10-09
Abstract: Disclosed is a method of an apparatus for assaying, in assay apparatus, for an analyte in a sample by specifically binding the analyte to a ligand having a detectable tag to form a complex, the presence of which can be determined quantitatively by measuring the amount of tag. In one embodiment, the sample is contacted in that apparatus with a test body of ligands so as to effect the specific binding. The body has at least two differently tagged different ligands in a predetermined ratio, at least a first of which tagged ligands being that which will specifically bind to the analyte. The second tagged ligand is one which will not specifically bind to the analyte or to other moieties in the sample. The relative non-specific binding characteristics of those ligands with respect to said apparatus are in a known or predetermined relationship. Quantitative measurement of those tags coupled to bound quantities of the ligands is then made substantially simultaneously. From the known proportion of ligands in the test body, the known ratio between the non-specific binding characteristics of the ligands to the apparatus, and the quantitative measurement of the bound tags, one can relatively accurately determine the specific binding of the first ligand to the analyte.

Each of the switch groups (SCH) contains a memory (DS) with several independently readable memory outputs (SA1 to SA4), through which the storage area can be accessed.  Each of the part signals of each memory address can be connected with a data output of the switch group through selectors SEL1 to SEL4.  The reading is controlled by a connecting memory (VB1 to VB4), which is assigned to a memory output (SA1 to SA4) and a selector (SEL1 to SEL4).            The coupling field may be composed of switch groups arranged in columns and lines, as required.  The data inputs (DE1 to DE4) of the switch groups (SCH) in one line are in parallel with one input of the coupling field.  Each of the data outputs of one switch group (SCH MN) is connected to a connection input (VE1 to VE4) of the following switch group.

Title: Interferometric signal analysis with modulation switching
Inventor: FERRAR CARL M
IPC: G01C19/72
Filed: 1991-06-11
Granted: 2001-01-09
Abstract: In a fiber optic rotation sensor, two phase modulators are symmetrically offset with respect to the center of an optical fiber loop and alternately excited by a waveform whose frequency alters the differential phase between counter-propagating light waves in the loop to maintain a fixed intensity signal at a detector upon loop rotation. The difference between the waveform frequencies is proportional to the speed of sensor rotation while the mean value of the waveform frequencies equals the frequency value in the absence of sensor rotation. In the alternative, a single modulator is excited by a waveform whose polarity is reversed at intervals of time.

Abstract: A swirling-flow burner is provided herein having an improved design including an outer, peripheral burner tube and a central oxidizer supply tube concentric therewith, to define an outer annular fuel gas channel. A fuel gas injector having a particular shape is connected to the outlet end of the fuel gas channel to provide an unobstructed flow of fuel injected toward the common axis of the fuel gas injector. A central oxidizer injector having a particular shape is connected to the outlet end of the central oxidizer supply tube. A cylindrical bluff-body having a particular shape is coaxially arranged within the oxidizer injection chamber. A swirler is installed on the bluff-body between its upstream end and its downstream end, the swirler having static swirler blades extending to the surface of the oxidizer injector. By this construction, the oxidizer supplied to the oxidizer injector is injected into a downstream combustion zone in a swirling flow by means of the bluff-body and the swirler, and is directed toward the common axis of the injectors and the combustion zone after having passed through the fuel gas injector. The oxidizer is mixed in a high temperature inner region of the combustion zone with fuel gas which was supplied to the fuel gas injector and was injected into the combustion zone in an inwardly flow direction towards the common axis of the combustion zone after having passed through the fuel gas injector. The combustion products which are in a low temperature outer region of the combustion zone have an external, recirculation flow direction.
