Abstract: An alarm for sensing different conditions of an ambient air presents a housing for an alarm circuit, the housing having  lobes  for  first,  second  and  third  circuit  sensors surrounding a single circuit alarm.  The alarm circuit delivers the current to a logic chip which produces a current for sounding the alarm in different patterns according to the sensed air condition.  The configuration of the housing depends the alarm below the housing proper so as not to interfere with the alarm sound.    The  housing  allows  the  installation  of  three  air condition sensors at one selected location.

Title: Method and apparatus for improved photoplethysmographic perfusion index monitoring
Inventor: POLOGE JONAS A
IPC: A61B5/026
Filed: 1997-04-02
Abstract: An improved method and apparatus for the monitoring perfusion of the tissue of apatient by arterial blood is provided. An optical path length change is calculated for a number of digitized samples of a received light intensity signal generated by a photo detector that received light directed into a patient's tissue by one or more light emitting diodes or laser diodes. The optical path length changes are summed over a predetermined time such as one half cardiac cycle or other set interval to generate a perfusion index. An average perfusion index value may also be generated. In calculating the perfusion index spectral content compensation may be employed to compensate for the variety of center wavelengths associated with the spectral contents of various emitters.

Title: Combined brush seal and labyrinth seal segment for rotary machines
Inventor: CROMER ROBERT HAROLD
IPC: F01D11/00
Filed: 1997-05-22
Abstract: A brush seal is comprised of arcuate seal segments having ends cut in a radial direction with bristles "canted" at an approximate 45° angle relative to radii of the segments, leaving triangular regions adjacent one end of each segment devoid of bristles at the segment interfaces. The brush seals are retrofit into conventional labyrinth seals with the backing plate for the bristles comprising a labyrinth tooth profile extending fully 360° about the seal, including those areas where bristles are not present. The sealing capacity is not substantially degraded, while affording significant sealing improvements over conventional labyrinth seals. Additionally, when retrofit into labyrinth seals with radial movement, the individual labyrinth seal segments are free to move radially independently of one another during transients.

Patent CA-2207135-A1 (CA)
Title: Nox sensor
Inventor: HASEI MASAHARU
IPC: G01N27/407
Filed: 1997-06-05
Abstract: A stable sensor designed to detect accurately the total NOx concentration under 100 ppm in terms of the NO gas concentration is made up of a first cell and a second cell with a gas diffusion aperture provided between the two cells. The first cell has a partition wall of a substrate of oxygen ion conductor containing zirconia as the main component and permitting a gas to be detected to  enter  the  zirconia  substrate;  oxygen  pumping electrodes are also formed on the first cell substrate which functions to expel oxygen in an atmosphere of the first cell to the outside and to reduce NO2 of the NOx gas to be detected to NO gas.  While NO gas entering through a gas diffusion aperture between the two cells flows into the second cell, a measurement is made of an electromotive force between a NO detection electrode formed in the second cell and a counter electrode also formed therein or a counter electrode formed on the reverse side of the zirconia substrate,  since such electromotive force corresponds to the level of the NO gas concentration and thus provides the total NOx concentration.
