Title: Process for coating particles with metal compounds
Inventor: SANG JEAN V
IPC: C04B41/45
Filed: 1990-01-12
Abstract: ABSTRACT    Process for coating discrete particles (preferably ceramic particles) with metal compounds, namely metal oxides and metal nitrides.  The process comprises forming a solution of an organometallic compound in a substantially anhydrous solvent that is substantially immiscible with water at ambient temperature, coating the particles with the solution and maintaining the particles substantially separate from each other while removing the solvent from the coating solution, e.g. by atomizing a slurry of the particles and the solution into a volume of heated gas.  The resulting particles coated with the organometallic compound are then heated to a temperature at which the organometallic compound is converted to the corresponding metal oxide.  If the final coating is to consist of a metal nitride, a carbon precursor (e.g. petroleum pitch) is also dissolved in the anhydrous solvent before the particles are coated, and then the oxide formed in the heating step is converted to the nitride by further heating at high temperature in the presence of nitrogen or a nitrogen precursor.  The process is capable of producing ceramic particles coated with a uniform, continuous, non-porous layer of metal oxide or nitride suitable for use, for example, as reinforcements for ceramic or metallic composite materials.

Title: Flexible intervertebral stabiliser, and process and apparatus for the determination or control of its tension before placing it on the spine
Inventor: BREARD FRANCIS H
IPC: A61F5/02
Filed: 1990-02-02
Abstract: The present invention relates to an inter-vertebral stabilizer having one or more flexible ligaments. Each flexible ligament can be engaged with two respective vertebrae and/or associated with two retaining elements, such as screws, each of which is suitable for being implanted in a respective vertebra. The present invention also relates to a process, and the associated apparatus, for determining or verifying the tension of such an inter-vertebral stabilizer before it is put into place on the spinal column. This process includes implanting, in each of the vertebrae concerned, a corresponding rigid rod extending outside the patient's body. The rods in each pair of adjacent rods are immobilized in an initial position. If the pain which is to be removed by the stabilizer persists, the process includes modifying the distance between the rods, then in immobilizing the rods in their new relative positions and in repeating the pain test. This cycle of operations is repeated, if necessary, until the pain disappears. The length to be allocated to the ligament is deduced from the distance then attained between the two rods.

Title: Polymerization of liquid crystalline monomers
Inventor: LITT MORTON H
IPC: C08F220/30
Filed: 1990-04-19
Abstract: Abstract of the Invention Polymeric compositions exhibiting superior physical properties, useful in the fabrication of composites and other applications, are prepared by the polymerization of thermotropic, monomeric materials having orderable molecular structures.  The monomers comprise molecules containing mesogen groups with side chains on either end thereof terminated with reactive groups, the reactive groups being separated from the mesogens by spacer atoms.  The monomers are polymerized in their crystalline or liquid crystalline state, or under conditions which assure that at least part of the monomeric molecules are in an ordered state. The reactive groups which are consequently in proximity with each other, are thereby capable of interaction without molecular diffusion, allowing substantially complete polymerizations to be achieved despite the increasing conversion and glass transition temperatures of the polymers being formed.

Title: Leak detector for containers
Inventor: LANGSDORF JOHN W
IPC: G01M3/36
Filed: 1990-08-17
Abstract: ABSTRACT      A leak detection apparatus and method provides uniform pressure application for leak testing of irregular containers.  The leak detector utilizes compressed air at a regulated low pressure and includes timing and pneumatic valve components for providing a timed pressure application and release cycle and an inflatable shroud which envelopes the container and applies substantially uniform pressure thereto.  Leak detection is accomplished by visual inspection of the container during and immediately after the pressure application cycle.  An alternate embodiment detector provides semi-automated testing.  Fill and vent valves are controlled by a microprocessor which receives data from a pressure transducer.  A read only memory stores one or more selectable decay functions and the microprocessor compares the pressure decay rate of the shroud and the container under test with an appropriate stored function to determine whether the container is leaking and provides a two-state (Accept-Reject) output.

IPC: H01H9/16
Filed: 1990-08-20
Abstract: Abstract of the Disclosure A  microcomputer  repetitively  samples  a  signal representative of the instantaneous state of an electrical contact  and  initiates  a  count  in  response  to  the  first sample which  indicates  a  contact  state  different  from  a stored status of the contact,  The microprocessor counts up for samples indicating an active state of the contact and down  for  inactive  samples.   If  the  count  increases  to  a predetermined  count  representing  a  certain  net  count  of active  samples  when  the  stored  status  is  inactive,  the stored status is changed to active.   Similarly, the stored status  is  changed  from  active  to  inactive  if  the  count decreases  to a predetermined  count representing a certain net count of inactive samples.  The time of the first sample which indicates a contact state different from the stored status of the contact is stored as a temporary time.  If the stored contact status is changed, the stored temporary time is saved as the valid time of the change in status.   The microcomputer maintains lists of contacts having an active status and those having an inactive status, and keeps track of a separate sample count for each contact monitored.

Filed: 1990-08-29
Abstract: METHOD AND APPARATUS FOR MODEL-BASED CONTROL           OF AN OPEN-LOOP PROCESS   Abstract of the Disclosure A method and apparatus For controlling a model based open-loop process and more specifically, the concentration of a drug delivered intravenously to a patient as a function of the rate of infusion. A three-compartment pharmacokinetic model is preferably used to determine the plasma drug concentrations corresponding to two arbitrarily selected rates of infusion. Based upon the linear relationship between corresponding data pairs, each pair comprising a rate of infusion and a corresponding plasma drug concentration, an interpolated rate is determined by a microprocessor (100) as a function of a specified plasma drug concentration, in accordance with program steps stored in a read only memory (ROM) 104. The actual infusion rate of the drug during successive time intervalsis repetitively used to compute the plasma drug concentration at the end of eachtime interval. In each successive iteration, state variables from the previous computation of the plasma drug concentration are used to determine the next interpolated infusion rate. Any interruptions in the output from an infusion device (112) and variations from the interpolated value of the infusion rate arecompensated. Using this open-loop control method and apparatus, the specified plasma drug concentration is rapidly achieved.
