Abstract: A competitive enzyme-linked immunosorbent assay (ELISA) for the detection of antibodies is disclosed. This ELISA technique is more sensitive, more specific, and more accurate than known ELISA techniques. The com­petitive ELISA of this invention is particularly suited to the detection of human T-cell leukemia-lymphoma virus type III (HTLV-III). An improvement of the ELISA technique represented by the present invention lies in the use of a reaction buffer which suppresses non-­specific adsorptive reactions between the test substrate and the test antigen. Furthermore, the ELISA technique is improved by removing contaminants from the target atnigen preparation.

Abstract: According to the method, a glare-inducing light (15) is shined in the subject's eyes. A series of visually-perceivable patterns of varying apparent sizes, each pattern arranged around the light, is presented to the subject. Each pattern comprises a sequence of alternating light and dark segments (45,46). The pattern is preferably in the form of a broken outline of a circle (40) centered on a window (30) through which the glare-inducing light passes. 
     For each pattern presented, the subject is asked to indicate which if any dark segments (46) he perceives. The subject may also be asked how many dark segments (46) he sees and in what locations. 
     The smallest pattern whose dark segments (46) can be perceived by the subject indicates the size of the subject's glare-induced vision blockage.

Abstract: A magnetic read/write head (14) is mounted on a carriage (28) having a semi-circular recess (40) therein. A threaded lead screw (20) is partially surrounded by the recess (40). A partial nut (44) having an arcuate front surface (50) with two male thread segments (52) thereon engages the lead screw (20). The partial nut (44) is supported on the carriage (28) so that rotation of the screw (20) causes movement of the carriage (28) relative to the screw (20), in a direction parallel to the longitudinal axis (58) of the screw (20). The partial nut (44) is biased into engagement with the screw (20) by a coil spring (64) which extends between the partial nut (44) and a cap (60) which is spaced from the rear surface (48) of the partial nut (44). The spring (64) applies a constant, predetermined force on the partial nut (44). The direction of the spring force is substantially parallel to the longitudinal axis (56) of the spring (64). Thus, the head (14) can be precisely positioned by the rotation of the lead screw (20). Also disclosed is a method of positioning the magnetic head (14).

Abstract: To provide for energy-efficient non-polluting heat treatment of workpieces (W) which, during heat treatment, emit oxidizable or combustible substances, hot gases are generated in a hot gas generating chamber (2) by a jet burner (5) emitting a flame jet. The hot gas generating chamber (2) is connected through a hot gas outlet (7) with a processing chamber retaining the workpieces, and a recirculating inlet (8) to receive the gases from the processing chamber, after they have been contaminated or received polluting combustible components. The hot gas generating chamber is, additionally, in communication through a duct or gap (4) with an after-burner chamber (3). The process is so controlled that the temperature in the after-burner chamber is maintained sufficiently high to provide for complete combustion of any oxidizable components, and the volume of the after-burner chamber, including the gas passed thereto, is so controlled that a dwell time of the gases therein will obtain which is sufficiently long to provide for said complete combustion. Typical dwell times are 1-2 seconds. A closed gas circulating loop (9) between the hot gas generating chamber (2) and the processing chamber (1) is established, the throughput to which can be controlled, for example by a throttling arrangement (13, 130), based on sensed temperature by temperature sensors (12, 15) which then control the throughput of hot gases in the closed loop and the fuel and air supply to the burner.

Abstract: The enzyme-labelled molecular probes are used to detect biomolecules by an enzyme reaction. The method for detecting biomolecules comprises the biomolecules, which are in solution or contained in gels or bound to a solid phase I, being recognised by a molecular probe coupled to an enzyme, the enzyme which is coupled to the molecular probe or has been cleaved off being reacted with a substrate in the presence of a cosubstrate, and the reacted substrate being detected on a solid phase II or III. The molecular probes are particularly bound to aminoglucoside phosphotransferases and can be used, in particular, in molecular biology, genetics, genetic engineering, medicine, biology, agriculture, phytopathology and veterinary medicine. The detection method has distinctly shortened working out times and a considerably higher amplification factor, and the detection on a second solid phase makes it possible to employ the biomolecules in a plurality of identical or different detection methods.

Abstract: A fast and flexible data decompressor decodes data, such as that encoded by CCITT Group 4 facsimile machines, to produce display data. In the decompressor, a microprocessor controlled by microcode evaluates variable length codes each representing a series of data cells, each data cell in a series having a single value assigned thereto. The variable length codes have a first code type, such as vertical codes and pass codes used in two-dimensional coding schemes, are decoded by the microprocessor. The variable length codes having a second type, such as one-dimensional horizontal codes, are decoded by a pair of look-up tables in read only memories (ROM's). One ROM determines the length of the code and the other determines the run length of the series of data cells represented by the code. A shifter which receives encoded data is shifted by the length of the code, whether determined by the code length ROM or the microprocessor. The microprocessor generates an intermediate code indicating the run length and the single value to be assigned to each of the data cells in the series of data cells, using the run length from the run length ROM if the code is of the second type. The intermediate code is sent to a bit generator which generates a series of bits corresponding to the data cells.
