Title: Supplying fluid
Inventor: BOUCHER ROBERT FRANCIS
IPC: G01F1/20
Filed: 1992-02-26
Granted: 1996-08-20
Abstract: A package burner has a fan rotatably driven at constant speed.  Air from the surrounding atmosphere is induced by the fan through an open end of a conduit which guides the air to the fan from which the air is propelled down an outlet passage to mix as combustion air in a chamber with fuel gas from a gas supply nozzle so that flames issue from the chamber.   A valve in the conduit or outlet passage can be set to regulate how much air is supplied as combustion air.  A fluidic oscillator has an inlet open to the atmosphere and has an outlet open to the interior of the conduit.  The observed frequency of the fluidic oscillator is a function of the flow rate of air through the fluidic oscillator and is also a function of the flow rate of air along the conduit.          Therefore the measured frequency of the fluidic oscillator can be used to calculate the amount of combustion air being supplied along the conduit in unit time.

Title: System for monitoring normality of operation of atm cross-connecting apparatus
Inventor: TANIGUCHI IKUO
IPC: H04L12/26
Filed: 1992-06-15
Granted: 1997-09-30
Abstract: A system for monitoring an ATM cross-connecting apparatus by rewriting a VPI conversion table to various values, inputting a test cell, and examining the test cell after the test cell passes through the ATM cross-connecting apparatus. Entries of a VPI conversion table are accompanied by traffic flags indicating whether or not the corresponding entry is occupied for use for user's signals. First, the traffic flags are examined. Each entry not occupied for user's signals can be freely rewritten. Each entry  occupied for user's signals is not rewritten. The examination of the test cell is carried out by comparing the test cell output from the ATM cross-connecting apparatus, with a reference cell which is expected from a normal operation of the ATM cross-connecting apparatus. The virtual path identifier converted in the ATM cross-connecting apparatus and contained in the output test cell, is expected corresponding to the above rewriting operations, and is contained in the reference cell.
Patent CA-2073855-C (CA)

Filed: 1991-01-18
Granted: 2007-04-24
Abstract: The invention is directed to the control of cellular autophagy, cellular agglutination and the immobilization of motile cells. Such control is useful in, for example, the treatment of cancer, contraception, termination of pregnancy, removal of pathogenic organisms and removal of any abnormal cellular growth (malignant or otherwise); as a diagnostic and analytical tool whereby cell structure can be studied and testing could be undertaken for the presence (and subsequent analysis) of pathogenic and non-pathogenic organisms; and in the manufacture of biochemicals whereby certain cells must be destroyed or otherwise contained. From surface analysis of normal and abnormal cells, specific receptors on abnormal cells which are either not present on normal cells or are only present insignificantly reduced numbers can be identified.  Alkaloids and other pharmaceutically acceptable compounds are preferentially recognised by the abnormal cells, and which bind thereto and subsequently destroy.
