Title: Phased array antenna
Inventor: HIRATA TOSHIKIYO
IPC: H01Q3/26
Filed: 1989-10-31
Abstract: Abstract of the Disclosure A phased array antenna used for radio communications which, when any of a multiplicity of power supply systems to antenna elements becomes faulty, can prevent the influences of the faulty power supply system from being exerted on the other systems and can obtain desired performances with use of the remaining normal systems.  The phased array antenna comprises means for detecting the presence or absence of a trouble or troubles in a necessary part of each block, in which power supplied to trouble one or ones of power supply systems having the trouble occurred therein is cut off or power supplied to the trouble system or systems is consumed at their predeter-mined terminating resisters on the basis of results obtained by the trouble detection means, thereby preventing the exten-sion of the trouble influences to the other normal power supply systems.

Title: Fixing device for cladding elements
Inventor: KURMANN BRUNO
IPC: E04F13/08
Filed: 1990-01-16
Abstract: ABSTRACT OF THE DISCLOSURE    A freely-movable fixing device is proposed for compensating for longitudinal changes in cladding elements caused by moisture and by fluctuations of temperature.  The fixing device includes telescopically-adjustable and fixable brackets, which are placed between the external wall of a building and a fixing frame run-ning parallel to the external wall of the building, the brackets being slidably secured to the fixing frame.  The brackets are slidably guided in a common plane which is positioned vertically to the external wall of the building.  In order to be able to support the fixing frame, movement of the brackets in the fixing frame is confined by an abutment.  By the use of this fixing device, the constructional tolerances are correctable by adjustment.

Title: Blended gasolines and process for making same
Inventor: WILSON EWERT J A
IPC: C07C7/20
Filed: 1990-06-20
Abstract: BLENDED GASOLINES AND PROCESS FOR MAKING SAME                   Abstract Blended gasolines are produced by the mixing of a butane-pentane  rich  component,  a  natural  gasoline component, and at least one octane-enhancing component. The mix is weathered during the blending operation to remove light-weight hydrocarbons comprising two, three and   four-carbon   components.      The   light-weight hydrocarbons, which preferably constitute less than 3 percent of the blended gasoline, can be recovered to generate power to run the process.  The liquid gasoline mixture is formulated to produce a desired octane rating, an environmentally acceptable vapor pressure, and a mix which, when burned in an internal combustion engine, produces a minimum amount of pollutants.

Title: Batch process control using expert systems
Inventor: SKEIRIK RICHARD D
IPC: B01J19/00
Filed: 1990-04-05
Abstract: Batch process (700) control is improved by defining a step endpoint condition (702) in an expert system (900) knowledge base;  using the expert system (900) to monitor for the occurrence of the endpoint in the batch process; and triggering a change in a batch process condition when the endpoint is found. Preferably, the expert system (900) and the batch process condition change are implemented as modules which execute under control of timing and sequencing functions in a supervisory control system, and the change affects a setpoint (or other control objective) in a continuous control system. Multiple instances of modular expert systems allow parallel process units to be easily controlled.

Title: Method of non-destructive inspection for resinous automotive bumper beams
Inventor: SATO SHOJI
IPC: G01M17/007
Filed: 1990-12-21
Abstract: ABSTRACT OF THE DISCLOSURE     A method of non-destructive inspection for resinous automotive bumper beams comprises applying flexural load to the center of a bumper beam by a pressing jig in a state that the both ends of the bumper beam have been pivotably sup-ported to gradually bend the bumper beam, measuring or determining the bending strain and energy absorption of the bumper beam upon the application of the flexural load, said energy absorption being calculated from said bending strain and flexural load, and judging the bumper beam to be good in quality only when the energy absorption of the bumper beam reaches at least a control value of the energy absorption, which is set up in advance, in a state that the bending strain of the bumper beam is at most a control value of the bending strain, which is set up in advance.  The control value of the energy absorption is determined by correcting the value of energy absorption upon destruction of a bumper beam, which has been found in a standard destructive test.          The control value of the bending strain is determined by cor-recting the bending strain in the standard destructive test.          These corrections are performed on the basis of the correla-tions between a plurality of data as to the energy absorption and bending strain in the standard destructive test and a trial destructive test, respectively.
