Title: Antenna system having azimuth rotating directive beam with selectable polarization
Inventor: TSUDA GEORGE I
IPC: H01Q15/24
Filed: 1989-12-06
Abstract: ANTENNA SYSTEM HAVING AZIMUTH ROTATING DIRECTIVE      BEAM WITH SELECTABLE POLARIZATION                       ABSTRACT      A rotating reflector is used to provide a beam scan throughout a predetermined angle such as 360`.  A circular polarizer is coupled with the reflector and converts  received  linearly  polarized  energy  into circularly  polarized  energy.     A  fixed  feed  is configured   to   receive   the   reflected   circularly polarized energy and converts such energy to linearly polarized energy.   The antenna system can receive the same linear polarization of energy throughout its 360` scan angle without polarization mismatch or orthogonal polarization losses.   The relative orientation of the two  polarizers  may  be  adjusted  to  receive  any orientation of linear polarization of energy throughout the scan angle.   For example, they may be oriented so that the antenna system receives vertically polarized energy,  slant  45`  linearly  polarized  energy,  or horizontally polarized energy.

Title: Turbine blade arrival time processor
Inventor: KOCH KARL C
IPC: G01H11/02
Filed: 1989-12-21
Abstract: ABSTRACT OF THE DISCLOSURE         An apparatus for detecting turbine blade passing time  includes a sensor for producing an input signal each time a blade passes the sensor.  Automatic gain control circuitry including a digital multiplier, peak detector and error amplifier regulates the amplitude of the input signal.  A zero-crossing detector produces an output signal each time the input signal crosses a reference axis.  A pre-trigger comparator produces a gating signal coinciding with the expected arrival time of the blade at the sensor. A gating device is responsive to the gating signal for conducting output signals which occur during the expected arrival time of the blade at the sensor.  A monostable vibrator produces a digital pulse coinciding with the time at which the blade passes the sensor.

Patent CA-2010303-A1 (CA)
Inventor: RICCI ANTONIO
IPC: B01L7/04
Filed: 1990-02-19
Abstract: The apparatus of the present invention can be used to measure sedimentation rate of samples. The samples are placed in a sample rotor and are rotatable about a sample rotor axis.      The sample rotor axis can be moved into two positions. In one position the sample rotor axis is substantially horizontal and in the other position the sample rotor axis is substantially vertical. Rotation of the sample rotor axis about the sample rotor axis causes stirring of the samples when the sample rotor axis is horizontal. When the sample rotor axis is substantially vertical settling of the samples occur. Step rotation of the sample rotor brings the samples to a reading means in order to analyze the samples. An optical signal sensor moves long the sides of the test tubes for measuring the sedimentation rate.

Patent CA-2013668-A1 (CA)
Title: Method for input output configuration in a programmable logic controller
Inventor: SEXTON DANIEL W
IPC: G06F13/14
Filed: 1990-04-02
Abstract: ABSTRACT OF THE DISCLOSURE     A   method   is  provided   for   configuring   a programmable  logic controller (PLC) wherein the  PLC verifies that the actual I/O hardware configuration of the PLC matches an I/O configuration specified by  the user  prior to running a control program on  the  PLC. The   I/O  configuration  supplied  by  the  user   is collected in a configuration information  file.   The match   test   between   the  actual   I/O   hardware configuration and the configuration file is  performed both before the control program is run on the PLC  and continuously  during  the  execution  of  the  control program.  Depending on whether or not the user has set a  fatal fault flag, if a mismatch occurs at any  time between the actual I/O configuration and the requested I/O  configuration  in the  configuration  information file,  then the PLC either issues a halt or  continues to   execute  the  control  program  while   providing diagnostic/error  message  information  to  the  user. Advantageously,  any  memory space in the  PLC  memory which  is  not needed to fill the demands of  the  I/O request in the configuration information file  remains free for other PLC tasks.

Title: Apparatus and method for asynchronously delivering control elements with a pipe interface
Inventor: BONEVENTO FRANCIS M
IPC: G06F5/06
Filed: 1990-09-19
Abstract: A microprocessor system which includes a processor unit with system memory and a separate buffer memory, one or more subsystem adapter units with memory, optional I/O devices which may attach to  the  adapters,  and a bus interface.  The memory in the processor and the memory in the adapters are used by the system as a shared memory which is configured as a distributed FIFO circular queue (a pipe).   Unit to unit asynchronous communication is accomplished by placing control  elements on the pipe which   represent   requests,    replies,    and   status information.  The units send and receive control elements independent of the other units which allows free flowing asynchronous delivery of control  information and data between units.   The shared memory can be organized as pipe pairs between each pair of units to  allow full duplex operation by using one pipe for outbound control elements and the other pipe for inbound control elements. The control elements have standard fixed header fields with variable fields following the fixed header.   The fixed header allows a common interface protocol to be used by different hardware adapters.  The combination of the pipe and the common interface protocol allows many different types of hardware adapters to asynchronously communicate, resulting in higher overall throughput due to lower interrupt overhead.
