Title: Method and device for measuring gas transfer time inside an enclosed space, particularly in a shaft furnace
Inventor: FRANSSEN ROGER
IPC: C21B7/24
Filed: 1998-10-13
Abstract: The invention concerns a method for measuring gas transfer time inside an enclosed space, such as a blast furnace, which consists in injecting a gas, called tracer gas, in a point A or A' of the enclosed space, for example a nozzle, and in tapping in a point B of the same enclosed space the gas present therein, the point A or A' being different from point B; in detecting the presence of the tracer gas in the gas tapped in B, and deducing therefrom the time required by the tracer gas to travel from point A or A' to point B on the basis of the data supplied by the detection system. The method also consists in carrying out at least one in-situ measurement of the response time, that is a calibration, of the tapping system in B. The calibration consists in injecting at the tapping point, concerning the equipment to be calibrated, an amount of a predetermined gas and in measuring the time separating said injection and the detection of said gas in the tapping and detecting equipment. Various methods are described two of which use tapping pipes with coaxial tubes and one with a single tube pipe. In case a rare gas, such as helium, is used as tracer gas, the blow-down gas can be nitrogen and the calibrating gas can be a helium-nitrogen mixture.

Title: Enzyme-amplified assay utilizing chemoreceptor recognition sites
Inventor: HALLOWELL SUSAN F
IPC: G01N33/53
Filed: 1989-11-28
Abstract: ABSTRACT OF THE DISCLOSURE         The  disclosed  in-vitro  assay  method  can  test  for a  wide  variety  of  drugs,  toxic  substances,  etc.  which  have affinity  for  a  chemoreceptor  of  a  living  organism.  The chemoreceptor  is  provided  in  vitro  as  the  recognition  site for the drug, toxin, etc. in the analyte or sample to be assayed. Before  bringing   the  analyte   into  the  presence  of  the chemoreceptor,  a  known  amount  of  enzyme-labelled  ligand  for the chemoreceptor is provided,  and the binding of the ligand to the chemoreceptor inactivates or inhibits the enzyme "label" of the enzyme-labelled ligand.   Accordingly,  when the analyte contacts the chemoreceptor, a competitive situation is created; the ligand and the analyte are now in competition for the binding sites  of  the  chemoreceptor,  and  at  least  some  of  the previously-bound,  enzyme-labelled ligand becomes excluded from the binding sites, resulting in an increase of observable enzyme activity  in  the  system.   Determination  of  this  increase  in activity provides  a  detection or quantitative measure of the presence  of  drug,  toxin,  etc.  in  the  analyte.   If  desired, several drugs, toxins, etc. can be tested for at the same time in this method; moreover, even novel or unknown toxins or drugs can  be  detected  and  their  concentration  quantified.   Stated another way,  this assay combines the "enzyme-multiplification" effect of the enzyme-multiplied immuno technique ("EMIT")  with the biological sophistication of a receptor-based assay.

Title: Communication system
Inventor: MESTDAGH DENIS J G
IPC: H04L12/56
Filed: 1990-06-22
Abstract: This system includes a main station (MS) and a plurality of substations (SX/SZ) which include each a transceiver and are all connected in parallel to first (UL) and second (DL) unidirectional links on which recurrent first and second cells of fixed length are transmitted in opposite direction.  Each of these cells contains a plurality of signalling channels smaller than the number of substations.          When a substation has to transmit data it starts an allocation procedure wherein the substation cooperates with the main station and by which a channel is allocated to it.  Afterwards prior to transmitting the data the substation transmits a request signal in the allocated channel and starts transmission after having received from the main station a grant signal in the homologous signalling channel of a second cell.  De-allocation of a channel occurs as soon as the latter is no longer needed.
