Title: Multiple pintle rocket nozzle propulsion control system
Inventor: MORRIS JOSEPH W
IPC: F02K9/97
Filed: 1994-11-04
Abstract: A rocket motor assembly is provided with multiple pintle nozzles 6 and a controller for adjusting the pintle 16 position in the nozzle to generate a thrust differential for directional controls, while maintaining the combustion pressure at equilibrium pressure by maintaining the sum of the throat areas of all of the pintle nozzles constant, for example. In this manner, proportional thrust control and very high response times are achieved. The controller also includes a pressure correction circuit that senses any difference between the actual combustion chamber pressure and the selected equilibrium pressure upon which the thrust differential was based, converts that to an error value, and sends a command signal to each pintle actuator so that each pintle position is adjusted an equal amount to compensate for the sensed pressure difference and maintain the combustion chamber pressure at the selected equilibrium pressure.   <IMAGE>

Title: Method and apparatus for parallel processing in a database system
Inventor: HALLMARK GARY
IPC: G06F9/46
Filed: 1994-09-09
Abstract: The present invention implements parallel processing in a Database Management System. The present invention provides the ability to locate transaction and recovery information at one location and eliminates the need for read locks and two-phased commits. The present invention provides the ability to dynamically partition row sources for parallel processing. Parallelism is based on the ability to parallelize a row source, the partitioning requirements of consecutive row sources and the entire row source tree, and any specification in the structured query language (SQL) statement. A Query Coordinator (802) assumes control of the processing of an entire query and can execute serial row sources (804, 806). Additional threads of control, Query Servers, execute parallel operators. Parallel operators are called data flow operators (DFOs). A DFO is represented as SQL statements and can be executed concurrently by multiple processes, or query slaves. A central scheduling mechanism, a data flow scheduler, controls a parallelized portion of an execution plan, and can become invisible for serial execution. Table queues are used to partition and transport rows between sets of processes. Node linkages provide the ability to divide the plan into independent lists that can each be executed by a set of query slaves. The present invention maintains a bit vector that is used by a subsequent producer to determine whether any rows need to be produced to its consumers. The present invention uses states and a count of the slaves that have reached these states to perform its scheduling tasks. <IMAGE>

Title: A particulate matter concentrator
Inventor: GORBUNOV BORIS
IPC: B01D49/02
Filed: 1996-11-15
Abstract: A particulate matter concentrator 1 for separating particles from a fluid comprises a surface 8 on which the particles are deposited, and an element 13 for heating the surface after deposition has taken place in order to evaporate the deposited particles. There may be an additional surface 7 spaced from the first surface 8, forming a path 6 for fluid flow between the surfaces. Surface 7 has a heating element 11 that may heat the surface to a temperature greater than that of surface 8, causing particles in the fluid to move by thermophoresis toward the cooler surface and be deposited thereon. Other separation methods such as using electromotive forces, magnetic forces, photophoresis, diffusion, electromagnetic forces or inertial forces may be employed instead of or in addition to thermophoresis to cause deposition on surface 8. The fluid is preferably air, but gases and liquids may also be used as the fluid medium. A pump means 5 may create a constant fluid flow rate through path 6. Each heat element preferably has a temperature control unit, and the surface 8 may have a cooling element. The heat element may be a halogen lamp and the surfaces 7, 8 may be of glass, aluminium or copper. The period of time for which the surface is at the evaporation temperature or greater is less than the deposition time.

Title: Jet engine hydromechanical fuel control system with variable delivery pump
Inventor: REUTER CHARLES E
IPC: F02C7/232
Filed: 1997-05-24
Abstract: The fuel pressures on either side of a fuel metering window 132, are ported to corresponding sides of a spool of a pump control valve 208. The position of the valve spool controls the fuel flow to either side of a pump control actuator 108, whose movement varies the displacement of pump 104. A bypass fuel flow, via line 188, upstream of the fuel metering valve, is also ported to the pump control valve. During steady-state pump operation, a relatively small and constant value of fuel flow is bypassed through the pump control valve and back to the pump inlet (via line 220). However, upon increasing or decreasing pump speed transients, the bypass fuel flow is increased or decreased in a proportional amount. In this way, improved control of the pump during transient conditions is achieved.

Patent GB-2330097-A (GB)
Title: Tool mount
Inventor: FRYER PAUL CHALFONT
IPC: B23Q17/09
Filed: 1997-10-07
Abstract: A tool 20 for machining a work piece 30 is mounted on automated machinery 50 using a multi-part sleeve 52. The parts 54, 56 of the sleeve 52 are ordinarily coupled together, but the parts are separable if a sheer or bending force is generated in the sleeve 52. Thus, if movement of the machinery 50 in the direction of the arrow results in the tool 20 colliding with step 28 in the work piece 30, the parts 54,56 de-couple, exposing cabling 58 which controls the tool 20. The de-coupling enables the positioning of the tool 20 to change, reducing the risk of damage to the tool, and the cabling 58 prevents the tool 20 dropping onto the work piece 30. Once the step 28 is removed, the parts 54,56 are coupled back together to enable further machining of the work piece. Preferably, the tool mount further comprises sensing means (100, figure 5B) to sense whether the parts 54,56 are coupled together, each part 54,56 including electrical contacts which are connected when the parts 54,56 are coupled together, and disconnected when the parts 54,56 are separated. The sensing means may then provide a warning signal to the operator or may automatically shut down the power to the tool 20. The parts 54,56 are preferably coupled together using interfitting profiles, which may be a snap-fit mechanism (figures 5A to 9B). Alternatively or additionally, the coupling between the parts 54,56 may be biassed by a resilient member (90, figures 8A,B; or 96, figure 10) urging the parts together. Alternatively, the coupling between the parts 54,56 may comprise magnetic or adhesive means.
