Patent CA-1329536-C (CA)
Inventor: CIPRIANO ANTHONY P
IPC: C23G3/02
Filed: 1987-08-26
Granted: 1994-05-17
Abstract: ABSTRACT OF THE DISCLOSURE          A system for pickling hot rolled carbon steel strip with hydrochloric acid completely and uniformly in optimum time.  The system consists of a series of cells made up of a number of section modules, each having a straight narrow passageway with monolithic top and bottom walls through which the strip and pickling liquor travels and a pair of cooperative conduits in the top and bottom walls for introducing the fluid into the passageway.  A wringer roll assembly with motor driven wringer rolls push the strip through each cell and consists of a housing having walls closely spaced to the rolls and a sealing element in the walls for the concentration of acid in each individual cell.  The rate of pickling on the strip is increased due to the turbulence of the circulating pickling liquor within each ell, the higher temperatures, and the high concentration in each cell; the latter two of which are due to the design of the section modules.

Patent CA-1330115-C (CA)
Title: Method and apparatus for iterated determinations of sensed speed and speed governing
Inventor: ADAMS LARRY L
IPC: G01P3/489
Filed: 1987-11-17
Granted: 1994-06-07
Abstract: ABSTRACT OF THE DISCLOSURE Methods and apparatus, preferably carried out with the aid of a programmed digital computer for iteratively determining the actual speed of an engine and iteratively updating a fuel rate command signal so as to govern and correctively remove any errors from the set point speed.  Jumps to a program subroutine are triggered by sensing the engine crankshaft to generate a predetermined number Q of pulses during the span of one revolution (where Q is an integer greater than 1), and each pass through the subroutine determines the actual engine speed as an average over the last whole revolution of the crankshaft.  There are thus Q iterations per revolution but each interation signals the speed over one whole revolution.  This results in wholly eliminating torsionally induced speed fluctuations, or the like, from the determined speed signal.  Each pass through the program subroutine also determines the speed error and updates the fuel rate command signal as a PID function of such error. Because this iterated updating occurs, not at a regularly timed rate, but at intervals which vary inversely with speed, the instructions of the subroutine program can be made very short and simple while nevertheless causing effective automatic tuning adjustments of the integral gain, stability and compensation factors.

Granted: 1992-09-15
Abstract: ABSTRACT Compositions of matter based on the reaction product of a dioxime compound and a polyisocyanate compound, made by reacting the compounds in an inert organic liquid in such a proportion that the ratio of oxime groups to isocyanate groups in the reaction is greater than 2:1,  and is preferably about 2.5:1.  The reaction product may be used in an adhesive composition which further includes an elastomer with a degree of unsaturation of greater than two mole percent,  which  is preferably an ethylene-propylene-diene terpolymer,  and which may further include a film-forming adjunct,  an inert filler material,  and an inert solvent. The adhesive composition, which does not require an oxidizing  agent,  may be made  into a  liquid adhesive composition by mixing with an inert organic liquid. The liquid adhesive composition may be used to bond rubber to metal, producing useful bonded and laminated articles, by coating at least one of the substrate surfaces to be bonded with the composition; bringing both substrate surfaces into contact with the composition layered therebetween; and maintaining contact under sufficient conditions of time, temperature,  and pressure to effect bonding.  Both cured and uncured rubbers may be bonded.

Title: Flutter exciter
Inventor: REED WILMER H III
IPC: G01M7/00
Filed: 1988-06-27
Granted: 1993-07-27
Abstract: ABSTRACT OF THE DISCLOSURE        A flutter exciter induces vibration either for actual aircraft flight testing or for wind tunnel model testing.  The basic flutter exciter unit is a pair of rotatable concentric cylinders mounted on either a fixed vane or an aircraft wing or a tail surface.  Each cylinder has a slot which allows the air flow to pass therethrough. By rotating the cylinders together, oscillating air pressure are induced on the fixed vane or the aircraft surface in which the cylinders are attached.  The cylinders may be mounted at  a trailing edge of either the fixed vane or the aircraft wing, to any tail surface, or on any other lifting surfaces of the aircraft itself.  Thus, because the flutter exciter can be made as a completely self-contained unit, it may be simply mounted to any suitable hard point on either the test model or the aircraft.  The power required to rotate the slotted cylinders is minimal, thus allowing the use of a low wattage motor.

Abstract: Screening methods to obtain suitable antibodies for use in immunoassays for analytes not ordinarily susceptible to detection by this means involves in vitro screening of panels of cells secreting a representative selection of antibodies.  An application of this method also permits the preparation of specific mimotopes which mimic the immunological activity of the desired analyte, which mimotopes can then be used as competitors in the immunoassay or can be used to immunize subject mammals in order to improve the specificity and affinity of the antibodies.  Methods to identify a particular analyte by its pattern of binding strength to a panel of related antibodies and to match an arbitrary analyte with an immunoreactive member of a panel of candidate antibodies are also disclosed.
