Patent CA-2101082-A1 (CA)
Inventor: WONG JACOB Y
IPC: G01J1/18
Filed: 1991-11-25
Abstract: A gas sample chamber (10) for use in a gas analyzer consists of an elongated hollow tube (21) having an inwardly-facing specularly-reflective surface (22) that permits the tube to function also as a light pipe for conducting radiation from a source (20) to a detector (16) through the sample gas. A number of apertures (24) in the wall of the elongated hollow tube permit the sample gas to enter and exit. Particles of smoke and dust of a size greater than 0.1 micron are kept out of the chamber by use of a semi-permeable membrane (28) that spans the apertures in the hollow tube. Condensation of the sample gas components is prevented by heating the sample chamber electrically to a temperature above the dew point of the component of concern.

Patent CA-2129102-A1 (CA)
Inventor: CHU PETER L
IPC: H04R3/02
Filed: 1993-01-08
Abstract: An improved echo cancelling device (18) for reducing the effects of acoustic feedback between a loudspeaker and microphone in a communication system. The device includes an adjustable filter (50) for receiving a loudspeaker signal and generating in response thereto an echo estimation signal. The device subtracts (54) the echo estimation signal from the microphone signal to produce an echo corrected microphone signal. During periods of time when the microphone signal is substantially derived from acoustic feedback between the loudspeaker and the microphone, the device adjusts (58) transfer characteristics of the filter (52) to reduce the echo corrected microphone signal. The improvement includes estimating from the adjusted transfer characteristics an energy transfer ratio representative of the ratio of the energy of the microphone signal to the energy of the loudspeaker signal. The device compares the microphone signal to the energy transfer ratio multiplied by the loudspeaker signal to identify periods of the time when the microphone signal is substantially derived from acoustic feedback between the loudspeaker and the microphone.

Abstract: A system for detecting the presence of bacterial growth in a plurality of sample vials incorporates a single test station moveable along each of the plurality of sample vials. In one embodiment, the sensor station is movably mounted on a rod, and that rod is movably mounted on a pair of spaced rods. The rod which carries the test station may move along the spaced rods to change the location of the test station in a first dimension and the test station is moveable along its rod to change location in a second dimension. In this way, the test station may be moved through two dimensions to move serially to the location of each of the plurality of sample vials. In another aspect of this invention, a bar code is associated with each of the sample vials, and the test station makes a reading of that bar code concurrent with a determination being made as to whether there is any bacterial growth in the sample vial. In this way, it is ensured that the results of the evaluation of whether bacterial growth is ongoing will be associated with the proper sample vial. 1n a third aspect of this invention, the sample vial incorporates a plurality of distinct types of bacterial sensors. Thus, the advantages of each of several types of bacterial sensors may be incorporated into a single sample vial.

Patent CA-2139609-A1 (CA)
Title: Roller dispenser machine
Inventor: FIELDING RANDY L
IPC: A23G3/20
Filed: 1995-01-05
Abstract: A roller dispenser includes a pair of counter-rotating cylindrical grid die rolls disposed adjacent a bottom opening in a hopper containing material to be dispensed. The grid die rolls have openings therein which assist in separating the material within the hopper prior to depositing the material on receiving articles or products passing therebeneath. Within the grid die rolls are shields or deflector plates which prevent the material entering the grid die rolls through openings in the upper surface of the grid die rolls from completely filling up the interior of the grid die rolls. Pin rolls within the grid die rolls push the material beneath the shields or deflector plates out through openings in the lower surface of the grid die rolls, making the grid die rolls self cleaning. An agitating bar assembly within the hopper keeps the head pressure or weight of the mass of the material within the hopper from forcing the material between the grid die rolls and allowing the grid die rolls to separate the material at a controlled rate.

Title: Disposable endoscope sheath
Inventor: REISDORF DENNIS
IPC: A61B1/00
Filed: 1994-07-21
Abstract: The disposable endoscope sheath (10) includes a low-profile sleeve member (12) that cooperates with the endoscope shaft (36) to establish a relatively narrow irrigation space (86) between the sleeve member (12) and the endoscope shaft (36). The sleeve member (12) is intentionally shorter than the endoscope shaft (36) to accommodate a variety of different endoscope lengths that are longer than the sleeve. In various embodiments of the invention, the sleeve member (12) can be positioned to establish a predetermined distal gap (100) between the terminal end (94) of the sleeve (12) and the viewing end of the endoscope shaft (36). Irrigation fluid can thus flow across the viewing end of the endoscope flushing away any surgical debris from the viewing end
