Patent CA-2019782-A1 (CA)
Inventor: MERSCH STEVEN H
IPC: G01B11/14
Filed: 1990-06-26
Abstract: An apparatus or method determines the gap (11) between an assembly (12) of a tube (13) and a cylindrical float (14) located substantially concentric to the tube. An elliptically polarized light beam (A) at the wavelength for which the materials of the tube and the gap are transparent or translucent is along an optical axis (C). The index of refraction of the tube and float materials are greater than the index of refraction of the gap material. Means translates and rotates the assembly along and about its longitudinal axis (F) producing an illumination (B). A light filtering means (21) along the optical axis beyond the assembly blocks light of the illumination (B) reflected by the assembly and refracted by the tube (13), the gap (11) between the tube, and the float (14) and the float and transmits light of the illumination (B) refracted by the tube and the gap between tube and float. Light detection means (15) receives transmitted light and signals a signal processing means (16). The method has steps of transmitting the monochromatic beam of elliptically polarized light along the optical axis to the assembly, focusing the beam of light, translating and rotating the assembly through the light, producing an illumination, filtering the illumination by blocking illumination reflected by the assembly and refracted by the float, the tube and the gap between the tube and the float and transmitting the illumination refracted by the tube and the gap between the tube and the float.

Title: Selective detection of vapors
Inventor: ACHTER EUGENE K
IPC: G01N33/22
Filed: 1990-07-09
Abstract: ABSTRACT OF THE DISCLOSURE    A highly selective, sensitive, fast detection system and method are disclosed for detecting vapors of specific compounds in air.  Vapors emanating from compounds such as explosives, or stripped from surfaces using heat and suction from a hand-held sample gun, are collected on surfaces coated with gas chromatograph (GC) material which trap explosives vapors but repel nitric oxide, then are desorbed and concentrated in one or more cold spot concentrators. A high speed gas chromatograph (GC) separates the vapors, after which specific vapors are decomposed in two pyrolyzers arranged in parallel and the resulting nitric oxide is detected.  A low temperature pyrolyzer with silver produces NO from nitramines or nitrite esters; a high temperature pyrolyzer decomposes all explosives vapors to permit detection of the remaining explosives.  Also disclosed is a series arrangement of pyrolyzers and gas chromatographs and an NO detector to time-shift detection of certain vapors and facilitate very fast GC analyses.  The use of hydrogen as a carrier gas, plus unique collectors and concentrators, high speed heaters, NO detectors, and very fast, temperature-programmable GC's enhance selectivity, sensitivity and speed of detection.   3118d

Title: Method and apparatus for the production of bricks and the like
Inventor: MAULE ALEXANDER
IPC: B28B3/26
Filed: 1990-09-06
Abstract: In the production of kiln fired bricks and hollow structural tiles a substantial loss (about 3.5%-7%) occurs during drying and firing, principally in the bottom layers adjacent the kiln car deck. This can be minimized by reducing the size of the core holes in the bottom rows of bricks, large holes being maintained in the upper layers to reduce the load on the bottom bricks, economising in fuel and clay. The method and apparatus involve use of a longitudinally movable core plug for each hole produced the downstream end portion of which produces small holes while an upstream portion produces large holes, the shape being such that in cooperation with the extrusion nozzle uniform flow and compression are maintained to equalise final column swell sizes as much as possible for both large and small core hole brick preforms. The pressure of the clay flow can move the plug to the position for the production of large core holes, while an automatic controlled motor means move the core plugs to the position for the production of small core holes, the core plug can be moved to the position in which the smaller core hole size becomes zero for the production of solid "paver" bricks.

Abstract: FITTING ASSEMBLY FOR A COMPOSITE STRUCTURE          Abstract of the Invention An apparatus and method for securing fittings to composite structures such as those composites formed out of resin-embedded fibers is disclosed. The invention includes the use of support structures wrapped around the fittings such that the support prevents the fitting from movement when a compression load is applied thereto. The support serves to transfer the force of the compression load into the entire body of the composite structure so that the force will be absorbed by the structure. In one embodiment of the invention, the support structure comprises a composite fiber tow formed of high tensile strength fibers impregnated with a matrix material. The composite fiber tow is fibers wrapped around the fittings to form suspension strands. As the matrix material cures thecomposite fiber stiffens to hold the fitting in place against the composite structure.
