Title: System for synthesizing field programmable gate array implementations from high level circuit descriptions
Inventor: CANTONE MICHAEL R
IPC: G06F17/50
Filed: 1994-06-20
Abstract: A SYSTEM FOR SYNTHESIZING FIELD PROGRAMMABLE GATE ARRAY  IMPLEMENTATIONS FROM HIGH LEVEL CIRCUIT DESCRIPTIONS          Abstract:     A system is disclosed for synthesizing field programmable gate array (FPGA) implementations from high level circuit descriptions.  A designer may describe circuits using a textual language or a graphics tool.  The system will compile such circuit descriptions into technology mapped descriptions for use with FPGA's.      The system will support both random logic circuits and data path circuits.  The system uses advanced optimization techniques to produce efficient FPGA implementations.  Thus, the system produces high quality results while providing users with a high level of abstraction in design, and thus frees the user from architectural details of the target FPGA.
Patent CA-2126365-A1 (CA)
Inventor: FELMAN STEVEN W
IPC: C07C51/47
Filed: 1994-06-21
Abstract: This invention provides an improved process of recovering citric acid from an impure process stream such as fermentation broth by the addition of a strong acid or salts thereof to a concentrated solution of the citric acid. The process provides for essentially one step purification without the waste disposal problems or large capital investment required by either lime sulfuric or solvent extraction recovery processes. The recovery may be further improved by treating the mother liquor remaining after separation of the citric acid crystals to obtain an additional yield. The preferred strong acid is sulfuric acid and the preferred mother liquor treatment is an ion exclusion resin column. While the improved process is particularly advantageous when used as a one-step purification process for nitric acid directly from fermentation broth, it may also be used in conjunction with the various impure process streams generated by the lime sulfuric or solvent extraction recovery processes.

Title: Methods for providing homogeneous reagents
Inventor: CLARK FREDERIC L
IPC: B01L3/00
Filed: 1993-03-24
Abstract: 2129367 9320444 PCTABS00027 A method for modifying a liquid assay reagent to provide prolonged homogeneity thereof, particularly where the liquid assay reagent comprises microparticles for performing a heterogeneous immunoassay, is provided wherein the addition of an inert material to a liquid assay reagent achieves neutral density to thereby prolong the homogeneity thereof for extended periods of time. A method for the automated agitation of assay reagents to maintain the homogeneity thereof with an automated, continuous and random access analytical instrument is also provided. The automated mixing is accomplished by a back and forth motion of a carousel onto which assay reagent containers or packs are mounted with asymmetric pauses which can be completed within a short period of time. The carousel acceleration, velocity, distance moved, and pause-asymmetry are optimized to provide rapid assay reagent resuspension without foaming or bubble formation. Accordingly, periodic removal of assay reagent packs by an operator in order to mix the reagents is not necessary.

Title: Orthopedic casts
Inventor: STEWART RAY F
IPC: A61B19/00
Filed: 1993-04-28
Abstract: Orthopedic casts which comprise a casting polymer of melting point Tm which is preferably from 40 to 60 ·C. The casting polymer is preferably coated onto an elastically deformed fabric, so that the cast recovers when heated to a temperature above Tm. The cast preferably has an air flow permeability of 10 to 35 %  resulting from the presence of apertures of area 0.01 to 0.08 cm2, so that it can be rapidly heated by means of a hot air gun.  Preferred casting polymers comprise a side chain crystallizable (SCC) polymer, particularly one containing units derived from styrene or another high Tg monomer. The addition of certain other polymers, e.g. an ethylene/vinyl acetate copolymer, and/or certain inorganic fillers, e.g. calcium carbonate, wollastonite and talc, results in improved balance of tensile strength and elongation.

Title: Control device for drilling a bore hole
Inventor: LIW LARS
IPC: E21B7/06
Filed: 1994-11-22
Abstract: The invention relates to A rock drill guide tool. A sleeve arrangement (8) is placed around a tubular drill tube (9) which rotates during a drilling operation and through which drilling liquid is supplied under pressure during drilling intervals. The sleeve arrangement includes a plurality of support units (15, 16) which can be projected out into contact with the wall of a drill hole and which are placed circularly in the sleeve arrangement. The support units are intended to he moved out into engagement with the wall of a drill hole during drilling intervals, so as to prevent the sleeve arrangement from rotating during a drilling operation. The support units (15, 16) are adapted to be held against the drill hole with a frictional force which is sufficiently low to enable it to become overcome in an axial direction by downward pressure of the drill tube during a drilling operation and sufficiently high to latch the sleeve against rotation by the drill tube as the drill tube rotates. The support units (15, 16) are placed in at least two ring sections of the sleeve arrangement and are provided with elements (19; 20) which project out against the wall of a drill hole. These elements engage the rock so as to cut grooves into the wall of a drill hole as the drill is moved down during a drilling operation. The outwardly projecting elements of all shoulder ring sections are placed mutually sequentially in an axial direction along straight lines, so that the outwardly projecting elements that are located behind the foremost elements in each line of elements as seen in the drilling direction will move in grooves cut in the rock by the foremost elements as the drill moves downwards.
