Abstract: TITLE "Aromatic Polysulfone Compounds and their Manufacture"                              INVENTORS   Michael D. Guiver Oleh Kutowy ABSTRACT OF DISCLOSURE          This invention relates to aromatic polysulfone compounds and their manufacture.  More particularly, this invention relates to functional group containing aromatic polysulfones, and their manufacture by metalation with organo-lithium compounds, of halogenated (e.g. brominated or chloromethylated) aromatic polysulfone compounds.  The degree of halogenation of the starting material determines the sites that may be metalated, and the degree of metalation determines how many of these sites will be metalated.  At least one of the metalated sites may be treated with an electrophile so that the lithium at that site is replaced by a residuum of the electrophile.

Title: Extended process for a multiprocessor system
Inventor: BISHOP THOMAS P
IPC: G06F15/16
Filed: 1987-12-18
Granted: 1991-07-30
Abstract: EXTENDED PROCESS FOR A MULTIPROCESSOR SYSTEM             Abstract In a multiprocessor system, a program's execution that is controlled by controlling an extended process that spans a plurality of processors. The extended process comprises an user process on one processor for executing object code of the program and stub processes each on an individual one of said remaining processors for accessing system resources required for execution of the program. Each stub process gives the extended process access to the resources associated with the processor executing the stub process. Further, a stub process is unique to one particular extended process. Each stub process is interconnected to the user process by an individual virtual communication channel. The virtual communication channels are identified in each process by a port table that is unique to an individual process. When the user process accesses a local file, the access is through a user file table, a system file table, and an inode table. When the user process accesses a remote file, the access is through the port table, over the virtual channel identified from port table to astub process, and then through the stub process' user file table, system file table, and inode table.

Granted: 1991-03-26
Abstract: TRIP RECORDER   ABSTRACT    A system for monitoring, recording and displaying vehicle operating parameters is described, which is capable  of  simultaneously providing operating data for the driver, an on board summary of critical trip parameters,   and   storage   of  monitored  vehicle operating data for  subsequently  generating reports off-line which  describe in detail the selected trip information.    The  system  consists  of  a Vehicle Mounted Unit [VMU]  which  accepts  inputs  from a variety of sensors.   Using  these  inputs,  the VMU continuously  computes  the  various  parameters  in order to provide the operating data  as well  as the on  board  trip  summary.   Detailed data are simul-taneously stored in the  VMU  memory  for subsequent processing by an off-line computer.  The contents of the VMU memory may be transferred to the computer in a variety  of ways.  A direct connection can be made between the VMU in the vehicle and the computer; the VMU can be removed from the vehicle and subsequently connected  to  the  computer;   or  an  intermediate device,  such  as  the  optional Data Transport Unit [DTU] described, may be used to transfer VMU data to the computer.

Abstract: Abstract of the Invention A fluid motor having a gerotor gear set includes a first member having internal teeth and a second member having external teeth.  The second member is rotatably and orbitally mounted within the first member.  The teeth of the first and second members cooperate to define a plurality of variable volume working chambers.  Some of said working chambers expand and other of said working chambers contract upon relative rotatable and orbital movement between said first and second members.  A plurality of electrically controlled valves are provided, each working chamber having an associated valve.  Each valve selectively communicates, in one condition, its associated working chamber with an inlet passage, which is, in turn, connected to a source of pressurized fluid, or, in a second condition, its associated working chamber to an outlet passage, which is, in turn, connected to a reservoir.  Each of the valves is responsive to a respective electrical control signal for placing the valve in the first or second condition.

Filed: 1988-09-13
Granted: 1993-06-08
Abstract: IMPROVED SORTATION CONVEYOR          Abstract of the Disclosure An improved lever arm for a tilt tray sortation conveyor has formula defined unlatching and tipping cam sections.  The tipping cam section imparts a constant angular acceleration of about 20 radians/sec.2 to the tray during positive tipping.          Such angular acceleration produces a maximum tangential acceleration for any article on the tray, approximately equal to or less than the acceleration of a free falling body.  An improved tray latch or index plate has an inclined cam resisting rebound of the tray after initial tipping.  Integral shock absorbers disperse impact forces in tray tip-up apparatus and resist elongation of tip-up mounting pin holes.  Methods are claimed.

Abstract: An  acceleration  sensor  comprises  a housing having a magnetically permeable element, such as a steel washer,  secured  thereto  proximate with an end  of a cylindrical passage formed therein; a magnetic sensing mass in the passage which is displaced in response to acceleration of the housing from an initial position within  the  passage proximate  the  steel washer  to  a second  position  within  the  passage  when  such acceleration overcomes the magnetic bias of the sensing mass towards the steel washer; a pair of electrically conductive  rings  encompassing  the  passage so as to provide magnetic damping for the sensing mass during the displacement  thereof;  and  a  pair  of  beam  contacts projecting from the housing into the passage so as to be bridged by the sensing mass when the sensing mass is displaced to the second position within the passage. The  accelerometer  further  comprises  a  pair  of oppositely-wound  electrical  coils  encompassing  the passage proximate the initial position and the second position  of  the  sensing  mass  therein,  respectively. Upon the delivery of a direct current to the coils, the sensing  mass  is  magnetically  biased  to  the  second position within the passage, whereby the beam contacts are bridged  by  the  sensing  mass  to  confirm  the operability of the sensor.

Abstract: A novel system for remote detection and imaging of underwater objects is presented.  In accordance with the present invention, a laser is used to generate short pulses of light with pulse widths on the order of nanoseconds.  The laser light is expanded by optics and projected down toward the surface of the water and to an object.  Intensified CCD (charge coupled device) cameras (preferably two) are electronically shuttered after a time delay corresponding to the round trip propagation time and from to the object.  This timing eliminates light scattered by the water from in front of and behind the object.  As a result, the veiling luminance of the water is greatly attenuated and faint target signatures can be seen.  The resulting gated images (displayed on a CRT) have sufficient spatial resolution to classify and/or identify the object.  The imaging lidar system of the present invention takes advantage of the fact that all opaque targets will cast a shadow.  The exposure of the two cameras in the system are timed such that one camera gives an image of the object against the backscattered light from the water while the other camera gives an image of the shadow of the object against the backscattered light.  These two images are then subtracted to improve the detectability of the object.

Abstract: An initialization or synchronization method in which at least a predetermined number of synchronization messages are sent out over a two-way communication line.  The receipt of a synchronization message is awaited before terminating the transmission of synchronization message.  After the transmission of synchronization messages has been terminated the receipt of a non-synchronization message will complete the synchronization process.  However, certain conditions may cause synchronization to be restarted such as a predetermined number of consecutive error messages, failure to receive any message in a predetermined number of clock signals, receiving more than a predetermined number of synchronization signals, or a reset command.
