Patent CA-2089633-A1 (CA)
Inventor: BARTLETT DAVID W
IPC: F25B49/00
Filed: 1993-02-16
Abstract: An over-pressure control apparatus for a refrigeration system provides for non-atmospheric venting of an evaporator during over-pressure conditions.  The control apparatus includes a sensor for indicating evaporator pressure, a storage vessel for receiving liquid refrigerant from the evaporator, and a controller responsive to the sensor.  The controller acts in response to the reading of the sensor to selectively open and close at least one control valve coupling the storage vessel to the evaporator and condenser of the refrigeration system. Liquid refrigerant is vented from the evaporator to the storage vessel in response to a detected over-pressure condition.            The over-pressure control method hereof acts to vent liquid refrigerant from the evaporator at a predetermined pressure above normal operating pressure, but below the pressure where emergency venting of refrigerant vapor from the evaporator to the atmosphere is required.  The liquid refrigerant vented from the evaporator can be returned from the storage vessel to the refrigeration system after the evaporator is restored to normal operating pressure.

Patent CA-2095805-A1 (CA)
Inventor: SMITH DON W
IPC: F23J3/00
Filed: 1993-05-07
Abstract: A self-adjusting joint packing for a sootblower of the type having a stationary feed tube gland with an overfitting lance tube which is moved within the combustion device to emit a blowing medium for cleaning purposes.  The joint packing gland mechanism causes the axial loading on the joint packing which forms a seal between the lance tube and the feed tube to be automatically adjusted upon each sootblower actuation cycle. The joint packing gland includes an actuator which engages the sootblower  frame  upon  actuation  of  the  sootblower  causing relative rotation between the actuator and lance tube.   A friction clutch is interposed between the actuator and a threaded gland to transmit rotation only when a packing preload force is below a predetermined level, thus adjusting packing force when needed.

Patent CA-2096454-A1 (CA)
Title: Method for tachycardia discrimination
Inventor: BAUMANN LAWRENCE S
IPC: A61B5/0452
Filed: 1993-05-18
Abstract: A cardiac discrimination method in which feature values of a heart related signal (e.g., cardiac biopotentials) determined to be non-baseline are compared with feature values of a heart related signal determined to be normal baseline. The feature values are extracted on an event-basis (a periodically), for obtaining feature values of a complex. For each complex, the feature values form a sequence with the value having the largest absolute value for the sequence given special identity as a fiducial point. The normal baseline complexes' characteristic sequence and a non-baseline complex's sequence are aligned according to the fiducial points, and unoccupied positions on the ends of the sequences resulting from the alignment are filled with zeros to create normal baseline and non-baseline vectors. The similarity value and dissimilarity value of the normalized non-baseline vector with respect to the normalized normal baseline vector are determined. The type of tachycardia (VT or non-VT) and consequently the selection of appropriate therapy are determined by the location in a discrimination plane of a discrimination point, the coordinates of which are equal to the similarity and dissimilarity values. In addition, the location of a similarly generated hemodynamic discrimination point can be used to discriminate hemodynamically stable and unstable tachycardias based on the features derived from events in hemodynamic related

Title: Optical illumination and inspection system for wafer and solar cell defects
Inventor: POLLARD HOWARD E
IPC: H01L21/66
Filed: 1994-03-10
Abstract: ABSTRACT OF THE INVENTION            An embodiment of an optical inspection system for detecting  cracks  in  a  silicon  wafer  or  in intermediate layers of a solar ceil is disclosed including a laser for providing a coherent light beam.  The laser may be a typical HeNe laser.  A video camera sensitive to near infrared frequency light is disposed co-linear with the laser and includes a macro-zoom lens.  The solar panel that is to be inspected is located in a test plane and in the field of view of video camera.  The laser is used to aid in directing the camera onto the solar panel.   A first quartz-halogen collimated light source is projected through and filtered by a long pass filter which passes wavelengths of 1.0 micron. The filtered collimated light from the light source is projected onto the surface of a white paper panel.    The source of the white paper contains irregularities on the same order as the 1.0 micron wavelength  of  the  light  through  the  long pass filter.    These  irregularities  cause  the  light reflected from the white paper to diffuse.   The white paper is positioned such that the diffuse light reflected therefrom falls upon the surface of the solar panel in the test plane.   Because the light rays reflected from white paper are diffuse they strike the surface of the solar panel at a plurality of various angles.   As the light rays pass through the solar cell layer interfaces will be reflected in the direction of the camera. Those rays which fall in the path of the field of view of the camera, become the object image from which a real  image  is created and may be viewed on a control monitor.  Cracks in the solar cell silicon layer or glass  covers  can  be  observed  on the control monitor, and printed by a video graphics printer  or  stored  via  a  VCR  for  permanent documentation purposes.
