Patent CA-2009851-A1 (CA)
Title: Aiming mine equipped with an optical target detector
Inventor: PAECH JOACHIM
IPC: G01S17/02
Filed: 1990-02-12
Abstract: ABSTRACT     An aiming mine includes an optical target detector (12) having at least one laser range finder.  In order to be able to automatically detect and attack targets over a large azimuth angle range, the optical target detector rotates during the search process.  The ranging values obtained from the at least one laser range finder are processed in a control and evaluation circuit (60) and are compared with measured values from an earlier time to obtain a firing signal.  The corresponding reflection profiles are preferably also compared.

Patent CA-2013348-A1 (CA)
Inventor: FLING RUSSELL T
IPC: H04N5/10
Filed: 1990-03-29
Abstract: A detector for vertical synchronizing pulses comprises a nonwrapping up/down counter and a comparator. The counter samples the level of a composite synchronizing signal at a sampling rate.  The counter has a numerical output which increases responsive to detection of said level during a sample interval and decreases responsive to nondetection of said level during a sample interval.  The comparator generates a vertical sync detection pulse when the numerical output of the counter is greater than a reference value.  In order to provide hysteresis, the numerical value is alternately one of first and second numerical reference counts, the first reference count being greater than the second reference count.  The comparator initiates the vertical sync detection pulse when the numerical output of the counter rises above the first reference count and terminates the vertical sync detection pulse when the numerical output of the counter falls below the second reference count.  The numerical reference supplied to the comparator is changed at times corresponding to initiation and termination of each vertical sync detection pulse.  A pulse shaping circuit may comprise a latch for sampling the output of the comparator and generating a vertical synchronizing signal.

Patent CA-2024786-A1 (CA)
IPC: F01D9/04
Filed: 1990-09-06
Abstract: Docket No. 0639-IR-TH     ABSTRACT OF THE DISCLOSURE      The nozzle has a full complement of blades, for use, for example, in a compressed-air turbine. However, a pair of peripheral walls, at opposite sides of the nozzle platform block nozzle blade groups.  The walls prevent fluid flow through those blade groups and, consequently, the nozzle has limited power.  The method teaches the machining away of as much of the walls as is necessary to enhance the power of the nozzle by exposing more of the nozzle blades to free fluid flow therethrough. By providing such walled, fully bladed nozzles, and removing portions of the walls, one can meet any power requirement, from full power to any practical minimum; by removing the walls entirely, or removing only a minor portion of each, respectively.

Abstract: ARTICLE, TEST KIT AND SANDWICH ASSAY FOR THE DETECTION OF BACTEROIDES, INTERMEDIUS, BACTEROIDES GINGIVALIS OR ACTINOBACILLUS ACTINOMYCETEMCOMITANS            Abstract of the Disclosure One or more serotypes of any of the microorganisms Bacteroides intermedius, Bacteroides gingivalis and Actinobacillus actinomycetemcomitans can be sensitively and selectively detected in a sandwich assay.  This method comprises contacting a specimen containing antigen extracted from the microorganism with a microporous membrane having reactive antibodies affixed thereto as a water-insoluble reagent, and contacting the same antigen with detectably labeled antibodies thereby forming a immunological sandwich complex bound to the membrane.  After unbound materials are washed away, the bound complex can be appropriately detected.  The water-insoluble reagent is composed of particles to which the antibodies are bound.  The particles are substantially on the surface of the membrane as opposed to being embedded therein.  This assay enables detection of the microorganism without significant cross-reactivity with related organisms.
