Title: Electrode water ring
Inventor: CARLYLE ROBERT A
IPC: F27D11/10
Filed: 1990-08-03
Abstract: ABSTRACT OF THE DISCLOSURE     In an electric arc furnace corrosion and consumption of the graphite electrodes can be reduced by spraying water on the region above the molten bath.  This can be more effectively done by the present application which provides a water ring mounted on the electrode holder and substantially surrounding the elec-trode having nozzles which direct the spray of water onto the electrode.  The water ring has in inlet and an outlet so that there is a constant flow of water in excess of that required to emit a spray from the nozzles thereby providing cooler water and control pressure and avoiding vaporization of the water in the ring and enabling better control of the water spray.

Title: Expert system tester
Inventor: OSBORNE ROBERT L
IPC: G06F11/34
Filed: 1990-11-16
Abstract: 55,307 ABSTRACT OF THE DISCLOSURE             The present invention is an expert system test system which has the capability of exercising all combinations of data input types using specialized data test sets.  The specialized data test sets include a set of sensor values for each level of an operating system.  In this way all levels of diagnosis can be tested without testing every possible sensor value and combination of sensor values.  The test sets can be combined to produce various orders of testing allowing complex relationships between sensors and rules to be tested.  the system includes a test plan which is used by the testing system to iteratively apply the normal and specialized test data to the expert system.  Changing the sensor values produces outputs for each iteration which are compared to expected results or to a baseline.  Each test produces a log file which can be examined by the knowledge engineer for execution details.  More importantly, if exceptions are produced, the system produces and exception report which allows the knowledge engineer to determine whether the exception is abnormal or unexpected.  An output log is also stored as historical data and used with future tests to obtain a complete test regression comparison using conventional database comparison tools.  The system includes a test language which allows the user to formulate a test plan without the need for complicated programming associated therewith by 55,307 designating the rulebase to be used, and by defining the order of the test and the tests performed therein, along with exceptions which include exceptions which include simple, set and sufficiency type exceptions.

Title: Nested container holders
Inventor: LORENCE BRIAN S
IPC: B60N3/10
Filed: 1990-11-20
Abstract: NESTED CONTAINER HOLDERS                 ABSTRACT OF THE DISCLOSURE         This invention provides concealable cupholders (3, 5) with several beneficial aspects.  Conveniently, the cupholders may be activated by actuating a push-to-release catch (24, 25) so that the cupholders move outwardly in a controlled manner from a housing with the appearance that it is being driven by an electric motor.  The cupholders overlap one another in a compact manner within the housing.  When moved out of the housing the cupholders may be maintained in the overlapping position such that they jointly support a single beverage or, alternatively a release mechanism (30) may be activated, by the use of, for example, a kick-out spring (10) to permit the secondary cupholder (5) to pivot to a position substantially disposed away from the primary cupholder (3) such that both cupholders may support different containers.

Title: Combined boots/turnout pant
Inventor: ALDRIDGE DONALD
IPC: A62B17/00
Filed: 1991-05-07
Abstract: COMBINED BOOTS/TURNOUT PANT  Abstract of the Invention A combined turnout pant and boot provide an effectively continuous moisture barrier.  Each pant leg includes a moisture barrier liner and may include a first cuff.  To fasten the boot to the liner, a second cuff, which may be attached to the top of the boot, is pulled up to the bottom of the moisture barrier liner and first and second corrugated connections are sealed together.  The corrugated connections may be at one end of the second cuff and at the bottom of the first cuff; at the other end of the second cuff, with the second cuff being an extension of the liner and the first cuff, and at the top of the boot, or at both ends of the second cuff and at the first cuff and at the top of the boot.  Excess material on the second cuff permits the second cuff to fold down, tending to fall over the boot with the liner extending down over the boot with it, thereby providing a substantially complete moisture barrier between the pant and the boots.

Abstract: ABSTRACT OF THE DISCLOSURE A timer controlled flow valve which is characterized by a closure member which is biased in an open position wherein the flow of fluids through the flow passage is unrestricted.  An actuator is connected to a power supply such that when power is supplied the actuator causes the closure member to move from the open position to a closed position.  A bypass switch is provided to cut off the power supply to the actuator thereby maintaining the closure member in the open position when a flow of indeterminant time duration is desired.
Patent CA-2046834-A1 (CA)
Title: Underdrain for liquid purification systems
Inventor: WALTER THOMAS P
IPC: B01D24/46
Filed: 1991-07-11
Abstract: ABSTRACT             An underdrain lateral  for a  liquid purification system is described.  The lateral has three chambers, a primary chamber, a compensating chamber, and gas chamber.   Turbulence is minimized during cleansing of the purification media by isolating the gas from the liquid and the backwash liquid. This is accomplished by feeding gas into the gas chamber so that the chamber is occupied by gas only during cleansing.  Orifices in the wall between the primary and compensating chambers and in the baffle between the compensating and gas chambers provide compensation for even distribution of liquid in the lateral. The design also enables the use of cut outs in the gas chambers to equalize gas pressures and flow among the  laterals  and throughout the system bed and cut outs in the primary chambers to equalize liquid pressure and flow among the laterals and throughout the system bed.  Nozzles with threaded stems having gas inlet orifices may be used and the levels of the entrances to the nozzles adjusted by rotating the  stems to equalize backwash liquid flow among the nozzles.   To minimize liquid pressure for greater gas flow during cleansing, an insert in the stem, adjacent the gas inlet orifices, may be added.

Abstract: An air bag firing circuit comprises a firing path which  includes  redundant  acceleration  sensors,  i.e.,  two sensors of like threshold connected in parallel.  Each sensor comprises normally-open switch means operated by an inertial mass and shunted by a resistor.  A battery maintains a known voltage across the firing path while a microprocessor checks the integrity of the firing path by periodically reading and comparing the voltages achieved at various points thereabout.          The microprocessor further tests each sensor individually by electromagnetically biasing the sensor's inertial mass in a manner  so  as  to  close  the  switch  means  thereof  while determining  the  effect  of  such  testing  on  the  voltages achieved about the firing path.   Upon the detection of a sensor failure, the microprocessor electromagnetically biases the sensor's inertial mass in a manner so as to maintain the switch means  thereof  in  its  open  position,  whereby  the malfunctioning sensor is functionally removed from the firing path without  impairing the  function of  the other  sensor connected in parallel therewith.
