Title: Tunable electrorheological fluid mount
Inventor: DUCLOS THEODORE G
IPC: B60K5/12
Filed: 1987-08-11
Granted: 1991-05-07
Abstract: ABSTRACT OF THE DISCLOSURE            The mount has variable volume fluid chambers interconnected by fluid passageways and containing electrorheological fluid. Valves are arranged in series with a plurality of the passageways. Each valve has a flow area greater than that of the passageway in series therewith. Energization of a valve generates an electrical field effective to so increase the apparent viscosity of the fluid within the valve as to prevent fluid flow through the passageway in series with it. Selective energization of the valves, by suitable control means a associated therewith, varies the frequencies at which fluid inertia forces cause the mount to undergo abrupt changes in dynamic stiffness.          The valves may be located upon opposite sides of a central mount section through which the chamber connecting passages extend. Electrode elements of the valves are preferably so shaped as to minimize fluid drag and electrical concentra-tion. In one embodiment the passageways all communicate at one end wish a common variable volume chamber, while com-municating at their opposite ends with respective ones of a plurality of different chambers.

Title: Method and apparatus for implementing multiple lock indicators in a multiprocessor computer system
Inventor: GILLETT RICHARD B JR
IPC: G06F9/52
Filed: 1988-04-29
Granted: 1992-07-07
Abstract: Abstract A memory node in a computer system having multiple processors interconnected by a pended bus provides exclusive read-modify-write operations employing multiple lock bits.  A processor generates an interlock read command which is trans-mitted as a transfer over the pended bus to the memory node. Acknowledge confirmations are transmitted by the memory back to the processor two bus cycles after each bus cycle of the proces-sor transfer.  The processor transfer, including an interlock read command, is stored in a input queue in memory and processes in turn by the memory.  A first interlock read command to a specified memory location causes a lock bit to be set for that location and a first type of response message including the con-tents of the specified location to be generated by the memory and stored in an output queue.  The memory obtains access to the pended bus through an arbitration process and transmits a re-sponse message including the contents of the memory location specified in the interlock read command at an unspecified time after initiation of the interlock read command.  A subsequent interlock read command from the processor to the same memory lo-cation will result in a denial of access to the specified loca-tion and in the generation of a second type of response message by the memory which indicates that the specified location is locked.

Granted: 1993-03-30
Abstract: ABSTRACT OF THE DISCLOSURE      A ceramic article having good fractured toughness comprising substantially spherical ceramic particles, which may be a ceramic oxide such as zirconia or zirconia combined with yttrium oxide. The ceramic particles are compacted and sintered to a density greater than 90 percent of theoretical density.  The article is characterized by a substantially uniform chemical composition and a substantially inclusion-free, homogeneous microstructure, which may be a metastable crystalline phase with less than 10 volume percent monoclinic crystalline phase.  The article is produced by dissolving, such as in water, a soluble compound containing a metal, e.g. zirconium, to form a solute.  A precipitation agent, such as sodium hydroxide or ammonium hydroxide, is combined with the solute to precipitate a hydrophilic colloid of the metal hydroxide, such as zirconium hydroxide.  The precipitate is formed into particles which are rapidly solidified while pre-venting agglomeration thereof.  The particles are dried, com-pressed to increase density and reduce size, calcined to convert the metal hydroxide to oxide, e.g. zirconium oxide, and then the particles are compacted and sintered to form a dense ceramic article.

Granted: 1992-01-07
Abstract: ABSTRACT    The arithmetic operations performed for floating point  format  numbers  involve  procedures  having  a multiplicity of major steps.  In the performance of the   effective   subtraction   operation,   the determination  of absolute value  of  the  difference between  the  operand  exponent  arguments  must  be obtained in order to determine the correct procedure.          In  the  present  invention,  a  difference  between  a subset  of  the  operand  exponent  arguments  is calculated and the result of this calculation is used to  anticipate  the  correct  procedure.   By  careful selection of the anticipated correct procedure, when the selection  is  erroneous,  the  correct  result  is immediately  available.   The  availability  of  the correct result is achieved by selecting the subset of operand exponent arguments so that, in the event that the result is erroneous,  the correct difference is such that the associated operand fraction (i.e., to be  shifted  by  the  amount  of the  difference)  is shifted completely out of the operand fraction field (stored in a register).

Abstract: Selective bromination of alkylarenes to the alpha dibrominated derivative is desirable as a precursor for the selective production of, for example, the corresponding aromatic aldehyde.  Improvements in the extent of selectivity of the product and/or its rate of production can be obtained by employing a photolytic reaction between the substrate, hydrogen peroxide and hydrogen bromide using mole ratios of H2O2:substrate of about 2.8:1 or higher, preferably 3.2:1 to 3.5:1 and of bromide:substrate of over 2.5:1, preferably about 2.8:1 to 3.2:1 and progressive controlled introduction of the H2O2, the reaction being carried out in the presence of a substantial amount of an organic solvent, and preferably more than 5.5 volumes per volume of substrate, whilst irradiating with light preferably having principal emissions in the range of 250 to 600 nm.  The reaction mixture is preferably maintained at 50 to 60C.  The reaction often takes from 5 to 12 hours, of which period hydrogen peroxide is introduced progressively into the reaction mixture during preferably the first 3 to 5 hours.  The process is especially suitable for deactivated alkylarenes, such as o-nitrotoluene.

Abstract: ELECTRODE CASTING SYSTEM      ABSTRACT            A system for casting electrodes includes a row of stationary, adjacent, plate casting molds flanked by a launder containing molten metal and a walking beam conveyor. One or two travelling carriages straddle the molds, launder and conveyor.  A travelling carriage comprises a pair of rotary dippers, a pair of tipping dispensers and electrode lifting means.  Each dipper scoops a predetermined amount of molten metal from the launder and,  while rotating, discharged it into a dispenser.  When filled, the dispensers simultaneously tip to fill a mold from both sides of a mold centre line over substantially the full length of parallel sidewall portions of the mold,  whereby wave action is dampened and molten metal solidifies with even thickness and without flash.  The bottom of the mold is water-cooled during casting.  While an electrode is cast in one mold, the lifting means lifts an electrode from an adjacent mold and transfers it onto the conveyor which then moves electrodes over a distance equal to that between electrode centre lines. The operation of the travelling carriage, dippers, dispensers, water sprays, lifting means and conveyor are carefully timed,  sequenced and concurrent where possible.     Using two travelling carriages over a row of 20 molds, a production rate of about five electrodes per minute is achieved.
