Abstract: A homogeneous specific binding assay device, a method for its preparation, and a method for its use in determining a ligand, such as antigen, hapten, or antibody, in, or the ligand binding capacity of, a liquid sample. The test device comprises a solid carrier member, such as a fibrous web matrix, e.g., paper, or a polymeric film or gel, incorporated with reagents for a homogeneous specific binding assay system which produces a detectable response, usually an electromagnetic radiation signal, that is a function of the presence or amount of the ligand in or the ligand binding capacity of the sample. Useful homogeneous specific binding assay systems include those involving enzyme substrate labels, enzyme prosthetic group labels, and enzyme labels. The detectable response preferably is a luminescent, fluorescent, spectrophotometric, or colorimetric response, which is measurable by visual observation or instrument means.

Abstract: In railroad operations, a method and apparatus for optimizing on-board rail lubrication for both curved and tangent track. The apparatus is mounted on the car body of the last locomotive of a locomotive consist behind the last axle. A lubricating device applies two different lubricants, one on the crown of the rail and the other on the gage side.      The amount and type of the crown lubricant are chosen such that the crown lubricant is totally consumed by the passage of the train wheels. The amount of application of the two lubricants is controlled by a microprocessor. A new sensor has been devised which measures degree of rail curve and estimates the angle of attack of the wheel on the rail by converting lateral displacement into either of the two quantities. This value is provided to the microprocessor.      Other sensors measuring speed, temperature, humidity, etc. provide input signals to the microprocessor. This invention not only reduces the friction coefficient between the wheel flanges and the rail but also reduces the forces between the wheel flanges and the rail. Both rail and wheel wear are reduced while simultaneously also reducing the fuel consumed in the train.

Title: Removal of hydrogen-containing silanes from organosilane mixtures
Inventor: BOKERMAN GARY N
IPC: C07F7/12
Filed: 1990-09-20
Granted: 1995-12-05
Abstract: The instant invention is a process for the removal of hydrogen-containing silane impurities from organosilanes with similar boiling points. In the instant invention, the hydrogen-containing silane is reacted with a hydrogen halide to replace the hydrogen on the silane with a halide and create a modified silane.  The substitution of the heavier halide for the hydrogen, increases the boiling point of the modified silane.  This increase in boiling point facilitates separation by distillation of the modified silane impurity from the desired organosilanes.

Abstract: ABSTRACT          A meteor scatter communications system for communicating between a master station (10) and one or more remote stations (11).  In one exemplary embodiment, a broad beam transmitter probe signal (30) is reflected from a meteor ionization trail to a remote station which then transmits a return data signal to the master station.  The master station receiver has a plurality of antennas (27-I ... 27-N) and a receiver beam forming network (28) which forms a plurality of narrow beam receive signals (32-I ... 32-N), one of which (32-X) has a high gain and corresponds to the narrow beam signal which illuminates the meteor trail and contains the reflected return data signal from the remote station.  The master station processor (12) selects such one narrow beam signal for processing the data therein.  The transmitter at the master station, if desired, can then transmit a further narrow beam message signal containing a message to the remote station using a transmit beam forming network (36) to provide a selected narrow beam transmit signal for reflection from the meteor trail to the remote station.
