Title: Rotary piston machines with a bearingless power train and stressless sliding parts
Inventor: WILLIMCZIK WOLFHART
IPC: F01C3/06
Filed: 1994-05-19
Abstract: ABSTRACT OF THE DISCLOSURE     This invention relates to rotary piston machines with a positive displacement  principle,  pressure-tight  work  chambers  and  a strong  and  friction-less  actuating  mechanism, or power train without power transmitting bearings. This absolute oil-free ope-rating  principle converts fluid or gas power directly and fric-tion-lessly  into  a rotating mechanical force and vice versa at high performances and with a high efficiency.          The  main  parts are two interengaging rotors, namely: a compact cylinder-rotor,  and a piston rotor as the only performance part without  co-rotating  bearings. Work chambers are defined by pi-stons  or plungers operating in cylinders with an axis of symme-try  in  any given direction, ergo are axial and radial machines included.  The  work  chambers  defining  elements  rotate along neighboring  orbits.  This  creates a useful short stroke motion between  the  piston  and cylinder but only in a co-rotating sy-stem. Therefore, and in spite of a reciprocating movement, these machines  have  no oscillating mass power. Furthermore, this in-vention  solves  the friction problem by a complete balancing of all  sliding  parts, that is, by eliminating any burdensome con-tact pressure.          A  machine  of  this  type can be made in any size and for every usable parameters, such as pressure, displacement volume, speed, and  performance.  The sum of all attributes of machines of this type  makes it ideal for a whole scale of oil-free applications, such as water hydraulic motors, oil-free power units, high pres-sure  water  pumps, vacuum pumps, metering pumps, dry running or water-sealed  compressors, and much more. Combinations of two or more  machines in one housing, and with one shaft only, are pos-sible,  for  instance a motor and a pump for energy recovery sy-stems etc. All these machines are not only able to work completely oil-free and friendlier environmentally, but also at highest performances combined with a high efficiency.

Filed: 1994-10-28
Abstract: SYSTEM AND METHOD FOR EXCHANGING COMPUTER DATA        PROCESSING CAPABILITIES Abstract of the Disclosure A system and method for exchanging data processing capabilities between computers. The computers exchange capabilities so that data transfer between the computers may be made in the most efficient data format possible for the two computers. A first computer, which will receive a data file, sends a list of data processing capabilities to a second computer, which will transmit the data file to the first computer. The transmittting computer examines the capabilities list of thereceiving computer as well as its own capabilities list and determines the most efficient data format for the transfer. The transmitting computer may process the data file into an intermediate format for efficient data transfer so that the receiving computer will process the intermediate data file into the desired data format. The capabilities list can be cached for future communication between the computers. The system can update the capabilities list and inform other computers whether theircached capabilities list is current. Capabilities can also be forwarded from onecomputer to another so that a third computer can determine the capabilities of the first computer from the second computer or the capabilities of the second computer from the first computer. The system is readily applicable to facsimile machines wherecustom and application data processing capabilities can be exchanged.

Title: Assay for determining sensitivity to activated protein c
Inventor: SCHWARZ HANS-PETER
IPC: C12Q1/56
Filed: 1994-11-30
Abstract: An improved assay for determining sensitivity to activated protein C in test samples has been developed to ensure rapid and accurate evaluations. This assay is based on measuring the conversion, by activated factor VIII within a test sample, of added factor X to an activated form. The activated protein C sensitivity of the test sample is determined by the relative inhibition of factor X conversion as compared to a control. A test sample that has decreased sensitivity to activated protein C will show relatively low inhibition, and vice versa.

Title: System for controlling a vehicle to selectively allow operation in either an autonomous mode or a manual
Inventor: PETERSON JOEL L
IPC: B60W30/00
Filed: 1995-08-10
Abstract: A system for controlling autonomous operation of a vehicle in response to speed and steering angle request signals from a navigator allows manual operation of the vehicle. The system includes a machine control module, an engine control module, and a transmission control module. An auto/manual select signal indicates to the machine control module whether operation should be in a fully autonomous mode or a manual mode. In the autonomous mode, a navigator produces a speed request signal and a steering angle request signal for the vehicle. The machine control module receives the speed and steering angle request signals from the navigator. From these inputs, the machine control module produces an engine RPM (revolutions per minute) control signal for the engine control module, a transmission control signal for the transmission control module, a brake control signal, and a steering angle control signal. In the manual mode, the machine control module will not interfere with normal, manual (i.e., manned) control of all vehicle systems.
