Patent CA-2211051-A1 (CA)
Inventor: BRADY DANIEL F
IPC: D06F33/37
Filed: 1997-08-04
Abstract: A dispensing system for dispensing chemical products to a plurality of utilization points utilizes a multi-port valve to selectively deliver use dilutions from a mixing apparatus to selected utilization points.      The multi-port valve utilizes a position sensor to provide positive proof-of-delivery by detecting the angular position of a rotor relative to a stator in the valve. The position sensor includes opposing annular arrangements of detectable elements and proximity detectors which rotate relative to one another about a common axis in response to rotation of the rotor such that detectable elements are oriented in proximity to a unique combination of proximity detectors at each of a plurality of predetermined angular positions. As a result, unique codes are output from the proximity detectors to positively identify positioning of the rotor at the predetermined angular positions.

Title: Method and apparatus for noninvasive determination of a disease state of a human eye
Inventor: KANDEL GILLRAY L
IPC: A61B3/06
Filed: 1996-06-05
Abstract: To determine a cataract or the degree of cataractogenesis in an eye of a patient, the patient views two lights juxtaposed, wherein each light comprises a mixture of two different wavelength lights. One of the lights is a fixed reference mixture, while the mixture of the other non-fixed light is varied until the patient observes a match between the two light mixtures in terms of hue, brightness and saturation. The luminance levels of the light components of the non-fixed mixture for providing the match and the proportionate levels of the two components are then determined. The shorter wavelength light of the non-fixed mixture is then substituted with a new wavelength light and the new mixture varied again until the patient observes a match as before. Alternatively, a polarization state of the shorter wavelength light is altered before determining a new mixture for obtaining a match. The luminance levels of the light components of the new mixture are then determined and another proportion obtained representative of the proportionate levels thereof. The first and second proportions are then compared to respective proportions of a standardized group. Deviations between the proportions of the patient and the standardized group indicate the existence of a cataract and/or the degree of a cataract precursor formation.

Inventor: PREIKSCHAT EKHARD
IPC: G01N11/00
Filed: 1998-02-06
Abstract: A hub assembly with improved sealing and anti-clogging properties comprising a housing body with a central, longitudinal aligned bore.  In the embodiment described herein, a rotating shaft unit on a consistency transmitter is disposed inside the central bore.  A flow cavity is formed on the distal end of the housing body which directly communicates with the central passageway of a pipeline containing flowing fluid material.  The flow cavity is sufficient in size so that fluid material inside the pipeline may freely flow therein during use.  Located around the distal opening of the housing body is an inner bushing made of graphite material.  Located immediately adjacent to the inner bushing is a compressible bellows seal which imparts a force against the adjacent, outer surface of the inner bushing.  The bellows seal which rotates with the rotating drive unit, has a smooth silicone-carbide end surface which is pressed tightly against the end surface on the stationary inner bushing thereby forming a tight seal.       A protective shroud is disposed over the bellows seal to adjustably hold the bellows seal on the outer drive shaft and to prevent fluid material from leaking between the drive shaft, the bellows seal, and the inner bushing. Formed on the outer surface of the shroud is a spiral groove which induces an outward flow of fluid material located within the flow cavity on the housing body towards the back side of a low drag coefficient impeller attached to the distal end of the outer drive shaft.

Title: Single step synthesis and densification of ceramic-ceramic and ceramic-metal composite materials
Inventor: DUNMEAD STEPHEN D
IPC: B22F3/10
Filed: 1996-10-02
Abstract: Ceramic-ceramic and ceramic-metal composite materials are disclosed which contain at least two ceramic phases and at least one metallic phase. At least one of these ceramic phases is a metal boride or mixture of metal borides and another of the ceramic phases is a metallic nitride, metallic carbide, or a mixture of metallic nitride and a metallic carbide. These composite materials may be made by a combustion synthesis process which includes the step of igniting a mixture of at least one element selected from titanium, zirconium, hafnium, vanadium, niobium, tantalum, chromium, molybdenum, tungsten, aluminum and silicon, or a combination of two or more thereof, at least one boron compound selected from boron nitride, boron carbide, or a combination thereof and an ignition temperature reducing amount of a metal selected from iron, cobalt, nickel, copper, aluminum, silicon, palladium, platinum, silver, gold, ruthenium, rhodium, osmium, and iridium, or a mixture of two or more thereof, provided that at least one of the aforementioned elements is different from at least one of the aforementioned metals. This process permits a high degree of control over the microstructure of the product and relatively low pressures are required to obtain high composite material density. A densified product having high density and a finely grained microstructure may be obtained by applying mechanical pressure during combustion synthesis. The composites have improved hardness, toughness, strength, resistance to wear, and resistance to catastrophic failure.
