Patent CA-2018342-A1 (CA)
Inventor: RUPPERT PAUL W
IPC: G01L11/00
Filed: 1990-06-05
Abstract: The hypsometer comprises an open boiling vessel consisting of a vessel flask containing the measuring fluid and of a vessel neck attached to said vessel. An electrical heating resistor plunges into said measuring fluid. A temperature sensor measures the boiling temperature of said measuring fluid. The hypsometer comprises an adaptive control system for stabilizing the position of condensation zone in the vessel neck which adjusts the heating capacity to a command value corresponding to the specific boiling temperature involved. In the simplest case, such control is realized by using, as heating resistor, a thermistor having a negative temperature coefficient. In this way, the heating capacity is adjusted, over the whole pressure range, to the specific needs. Thus, on the average, less heating capacity is needed, resulting in a considerable reduction of the battery weight.

Title: Molded composites
Inventor: WEAVER WILLIAM R
IPC: B29L9/00
Filed: 1990-06-19
Abstract: ABSTRACT       Molded composites, useful for manufacturing for example entry way doors, furniture components, building decorative or structural components, etc., are produced by a process in which a substrate and surface finishing film are placed in a mold, the mold is closed, and reactive polymeric precursors are injected between the substrate and the surface finishing film.  The injection pressure and the autogenous pressure incident to the curing of the reactive polymeric precursors deform the surface finishing film into intimate contact with a surface of the mold cavity, and simultaneously the polymeric precursors chemically bond to the surface finishing film.

Title: Bus master command protocol
Inventor: SCHMENK DAVID S
IPC: G06F3/06
Filed: 1990-11-02
Abstract: Abstract A bus master interface command protocol for use with a computer system having an intelligent mass storage disk array subsystem, including a bus master and microprocessor controller.  The command protocol permits the computer system to issue disk array commands to the controller at a logical level without having to issue disk specific commands.   The  disk  array  subsystem microprocessor controller reads the logical commands, translates the commands into smaller disk specific commands, and queues the  disk  specific  commands  for  processing.   Upon completion of the logical  command,  the bus master controller asserts control over the computer system bus and manages the transfer of data to or from the computer system memory.  The management of the disk array subsystem and the transfer of data is effectively off-loaded from the system processor permitting more efficient use of the processor.
