Title: A method and apparatus for remotely and portably measuring a gas of interest
Inventor: RYAN FREDERICK M
IPC: G01N21/35
Filed: 1990-04-19
Abstract: A remote gas measuring apparatus and method utilizes the optical absorption line characteristics to determine an amount of gas of interest as may exist in an area under study. The remote gas measuring apparatus includes a source of electromagnetic radiation that can be projected toward the area in question and a light collecting arrangement. The light signal received is coupled to a fast light switch modulator which modulates the light signal to a first frequency. A second modulating arrangement modulates the light signal to a second frequency and includes a birefringent etalon device having a periodic spacing equal to the periodicity of the absorption lines of the gas of interest. The second modulating means is further effective such that, when an electric field is applied thereto the transmission spectra associated with the light signal is shifted between spectra which coincide with the absorption lines and spectra which fall between the absorption lines. The light signal from the etalon device is then conditioned and input to a detector configuration which distinguishes between the light signal at the first frequency and the light signal at the second frequency in order to determine at least a quantity of the gas of interest.

Title: Method for reclassifying pcb transformers
Inventor: HORNECK CRAIG W
IPC: H01F27/14
Filed: 1990-05-24
Abstract: The present invention is directed to a method for reducing PCB concentration in an electrical induction apparatus containing a dielectric fluid with greater than 500 ppm PCB to a level of less than about 50 ppm PCB. Dielectric fluid containing greater than 500 ppm PCB is drained from an electrical induction apparatus, and the drained apparatus then is filled with tetrachloroethylene as a first interim dielectric fluid.  The  apparatus is then electrically operated with the first interim dielectric fluid so as to attain about an equilibrium PCB concentration in the first fluid.  The first interim dielectric fluid then is drained from the apparatus and replaced with fresh tetrachloroethylene as a second interim dielectric fluid. The apparatus then is electrically operated with the second interim dielectric fluid so as to attain about an equilibrium PCB concentration in the second fluid. The second interim dielectric fluid then is drained from the apparatus and replaced with a silicone fluid as a permanent dielectric fluid.  The apparatus filled with permanent dielectric fluid is electrically operated and the permanent dielectric fluid is filtered through a carbon filter, so as to attain a PCB concentration in the permanent fluid of less than about 50 ppm.

Patent CA-2019075-A1 (CA)
Title: Release for closure panel pull down mechanism
IPC: E05B47/00
Filed: 1990-06-15
Abstract: A vehicle body compartment is closed by a closure panel movable between an open position and a closed position.  A latch assembly mounted on the panel has a latch bolt spring biased to an unlatched position and normally maintained in the latched position by a detent lever.  A pull down mechanism includes a housing mounted on a vehicle body and a striker mounted thereon by a motorized vertically reciprocating drive unit for moving the striker between extended position and a retracted position.  When the panel is moved toward the closed position, the latch bolt engages with the extended striker to interconnect the panel with the striker.  The drive unit is energized and retracts the striker, thereby pulling the panel to its fully closed position.  To open the panel, the operator energizes the drive unit to move the striker from the retracted position to the extended position.  A plunger is mounted on the latch assembly and engages with the vehicle body so that progressive opening movement of the panel by the extension of the striker permits a spring to extend the plunger.  A cam device acts between the plunger and the detent lever of the latch assembly to cam the detent lever to the position releasing the latch bolt, thereby disconnecting the panel from the striker and freeing the panel for movement to the open position.

Title: Method and system for dispensing precise amount of fluid with automatic set reset
Inventor: LAMOUREUX ALAIN
IPC: G05D7/06
Filed: 1991-03-05
Abstract: METHOD AND SYSTEM FOR DISPENSING PRECISE        AMOUNT OF FLUID WITH AUTOMATIC SET RESET                   Abstract A method and an automatic control system for dispensing a desired precise amount of a fluid from a reservoir by automatic control of a pump.  The fluid is discharged through an operator actuable dispensing mechanism which is operated by a user.  More particularly, but not exclusively, the system is associated with a gas pump apparatus.  The system detects a slow-down or a stoppage in the discharge of the fluid by sensing a signal at the output of a counter which is provided with the gas pump.  These signals actuate the controls circuit to sense parameters of the counter whereby to initiate a slow rate of discharge of the fluid from the pump during a predetermined time period before a preset integral amount and after the slow-down or after the reactivation of the actuable dispensing mechanism if a stoppage of the mechanism was detected.  After the integral amount is reached, the pump is shut off during a shut off period of time after which shut off period of time, the pump is re-activatable by actuation of the actuable dispensing mechanism.  Accordingly, this system greatly facilitates the dispensing of a precise volumeric or cost amount of a fluid, such as gasoline.

Abstract: A photoconversion  device  comprises  a  plurality  of cells 1  each having a bipolar type sensor element T, the base of which is connected to a reset switch FET M and   is   also  capacitively  coupled  to  a  control electrode.  The device is  read  out  by  providing  a positive pulse to the base of the sensor T through the control  electrode,  and  is  refreshed  by  a   first operation  in  which the base is set to a preset level through the FET M and a second operation in which  the base-emitter  junction  of  the  sensor  T  is forward biased.  A control terminal 19 provides a  high  level reset  voltage to a main electrode region of the FET M through an emitter follower arrangement 18 to turn the FET  M  on  for  the  first  reset  operation  without providing a negative pulse  on  the  horizontal  drive line  2 which is connected both to the gate of the FET and  the  capacitively  coupled  control  electrode.          This permits a relatively high voltage read out signal to be provided on the horizontal drive line 2  without subjecting  the  line  to  an  excessive total voltage swing.

Abstract: An improved rectilinear building structure using diagonal tension members to resist racking to improve the tolerance of transitory transverse loads such as those that  are  produced  by  seismic  occurrences.    The improvement  comprises  placing  a  resilient  pad  in compression between at least one end of a tension member and a structural member whereby the resilient pad is compressed when the tension member is under tension so that  the  resilient  pad  deforms  under  the  transitory transverse load thereby increasing the ductility of the structure before fracture of the tension member occurs.
