Title: Improved method and reagent composition for performing leukocyte differential counts on fresh and aged whole blood samples
Inventor: MALIN MICHAEL J
IPC: G01N33/49
Filed: 1996-05-13
Granted: 2001-06-21
Abstract: The present invention provides an improved reagent composition and method to perform white blood cell differential counting and subpopulation analysis using both fresh and aged blood samples with accuracy and precision. The invention is particularly applicable for the analysis of aged blood samples that have been stored at room temperature for over a day, thereby allowing accurate and useful information to be obtained from samples that are normally considered to be suboptimal. The improved reagent composition and method are particularly related to the peroxidase method of white blood cell differential determinations. One aspect of the invention includes an improved aqueous reagent composition for carrying out the peroxidase method of differential counting. Another aspect includes the use of a rinse cycle and rinse solution devoid of hemolytic surfactant to alleviate the adverse effects of rinse carryover and to streamline and economize the analytical process, particularly when the analyses are performed on automated hematology analyzers and flow cytometry systems. The composition and method of the invention provide clinically useful data for the differential analysis of whole blood samples.
Patent CA-2005972-C (CA)
Title: Duplex communications method and system
Inventor: BEESLEY GRAHAM E
IPC: H04W88/02
Filed: 1989-12-19
Granted: 1994-03-29
Abstract: ABSTRACT         A method of establishing a digital time-division duplex radio communication link between one of a plurality of portable units and a base unit in a cordless telephone system.   Transmissions from the base unit are allowed only on a ping-pong basis with transmission bursts from all the active transmitters in the base unit being synchronised with one another. This prevents blocking of receiver sections due to co-sited transmitters transmitting at the same time on a different channel.   The difficulty of synchronising the transmission bursts of the active portable units with their respective transceivers within the base unit is overcome by allowing the portable unit to make an initial continuous call comprising multiple identical sequences of data containing units small enough to be completely received within the limited reception windows of the base unit.   After the initial call has started communication, an exchange of signals takes place on a ping-pong basis to establish synchronism between the portable unit and base unit.   Finally, if all is well, the system reverts to speech mode.

Abstract: A composition for separating out volatile pollutants from gases and exhaust gases comprising calcium hydroxide and water-soluble salts of sulfur-containing compounds, e.g., mercaptans, sulfides, polysulfides, polythionates and thiosulfates or elementary sulfur which are used in combination with surface-active substances. Possible ways to produce the composition include adding the sulfur-containing compounds to quicklime during slaking, to the slaking water or, subsequent to slaking, to calcium hydroxide. The compositions are used for removing the volatile heavy metals, particularly mercury, arsenic, cadmium, thallium, antimony and lead, at temperatures ranging from 0 ° C to 400 ° C. For this purpose, the composition is blown as powder into the exhaust gas stream, and the resultant products are separated out at fabric filters. Upon addition of surface-active substances, volatile organic pollutants are removed simultaneously with the afore-mentioned inorganic pollutants.

Granted: 2002-10-08
Abstract: A seal is provided comprising two parts and is made of synthetic material. An upper part has an internal thread, a continuous surface area and an axial external cylinder section. A valve tube is positioned above the cylinder section and is held in place by means of a conical intermediate piece. A lower part has an external thread, a continuous surface area and an axial internal cylinder section. A sealing bulge faces the external cylinder section and a valve pin held in place above it by means of connecting bars. By turning the upper part in relation to the lower part, the upper part is displaced axially in relation to the lower part. A sealing piece is fitted axially to the upper end of the valve pin. As the seal is screwed down, the sealing piece blocks the upper opening of the upper part. Its upper end is flush with or rising above the upper part, and the valve pin is enclosed by the valve tube. When the seal is screwed down on entirely the valve pin will be located outside the valve tube. A rib at the lower part and a baffle at the upper part cooperate to limit the rotation of the upper part in relation to the lower part to less than a full revolution.

Inventor: LACOSTE MARC
IPC: B32B18/00
Filed: 1992-02-17
Granted: 2000-11-21
Abstract: The anti-oxidation protection is achieved by forming an intermediate layer devoid of the element silicon between the surface of the silicon compound ceramic, such as SiC, and a silica based vitreous outer layer, such as SiO2, to be subsequently deposited. The intermediate layer is made of alumina (Al2O3) or an alumina precursor, so as to constitute a reaction barrier between the silicon compound and the silica outer layer on the one hand, and trap any amount of silica that may be formed by an oxidation of the silicon compound. There is thus achieved an anti-oxidation protection that is effective under both an active oxidation condition and a passive oxidation condition for the silicon compound.          A mullite interphase may also be formed between the silicon compound ceramic and the intermediate layer and/or between the intermediate layer and the vitreous outer layer.

Title: Well screen having a protective frame for a horizontal or high-angle well
Inventor: NAGAOKA TADAYOSHI
IPC: B01D29/15
Filed: 1992-07-31
Granted: 1996-11-12
Abstract: A well screen for a horizontal or high-angle well includes a screen main body and a protective frame.   The screen  main  body  has  screen  rods  arranged  in  the circumferential direction of the well screen and a screen wire wound on the screen rods.   The protective frame includes protective rods located outside of the screen wire in the circumferential direction and extending in the axial direction of the well screen, annular rod holding members spaced at intervals in the axial direction for holding the protective rods, and a protective wire wound about the protective rods. When the well screen passes through a bent section of the well, the protective frame slides in contact with the wall surface of the bent section thereby protecting the screen wire.  A gap of a predetermined value is formed between the protective rods and the outer surface of the screen wire of the screen main body so that, by adjusting this gap suitably, the screen wire will pass through a bent section of the well without contacting the protective rods.  Even if the screen wire contacts the protective rods, the screen wire will not receive a damaging force from the protective rods.

Granted: 1996-03-19
Abstract: An apparatus and method for reducing nitrogen oxide emissions from the products of combustion is provided in which a vortex  generator introduces natural gas, or other fluid fuel into the upper portion of a combustion device.  The fuel introduced forms vortices, such as vortex rings, and the fuel reacts with the nitrogen oxide in the combustion products to form ammonia-like compounds, hydrogen cyanide and similar compounds, and nitrogen.  The ammonia and cyanide-like fragments react with additional amounts of nitrogen oxide in the combustion products to form nitrogen gas, water vapor and carbon dioxide.  The vortex rings can be controlled and will maintain their integrity longer than puffs or simple jets of fuel.
