Title: Process for manufacture of ashing containers
Inventor: REVESZ ROBERT N
IPC: G01N1/44
Filed: 1992-02-25
Abstract: ABSTRACT OF THE DISCLOSURE:           Ashing containers which are useful for ashing analytic samples in microwave heated furnaces or muffle furnaces, and which are heat resistant, walled, light in weight, microwave transmissive and porous, are manufactured by a process in which quartz microfibers are suspended in water, deposited on a foraminous form to produce a container shape, dried, using vacuum and heating, removed from the form and sintered to final form retaining shape.          The ashing containers made are capable of being used repeatedly in ashings effected at temperatures of about 1,000°C.  The ashing containers, being light in weight, facilitate accurate weighings of ash produced, and the containers heat up and cool down quickly.          Additionally, they can be used for analysis of flours, in which ethanolic solutions of magnesium acetate are flamed, without necessitating separate flaming operations to avoid explosive combustions and losses of sample or ash.  The invented processes can also be used to make similar containers of borosilicate glass useful as containers for materials to be heated to relatively high temperatures.

Patent CA-2072831-A1 (CA)
Inventor: HILL KENNETH O
IPC: G02F1/225
Filed: 1992-06-30
Abstract: Efficient, narrow-band rocking filters have been made in polarization-maintaining monomode optical fiber by photoinducing periodic birefringent gratings along the length of the fiber. These gratings, fabricated with a period chosen to provide synchronous coupling between the two principal states of polarization of the LP01 mode at a preselected wavelength, gently rock to and fro the principal polarization axes of the fiber. To photoinduce the grating, the fiber is exposed periodically along its length to a U.V. light beam which is incident at right angles to the geometrical axis of the fiber and is directed .pi./4 radians with respect to the principal axes. Efficient polarization mode conversion at 1.3 µm with the fiber gratings are obtained.

Title: Control system for diesel particulate trap regeneration system
Inventor: STIGLIC PAUL M
IPC: F02D9/04
Filed: 1990-06-26
Abstract: A control system for regenerating a particulate trap in the exhaust system of a diesel engine includes control logic which controls the air/fuel ratio of the engine by operating a backpressure valve in the engine exhaust system to provide a proper amount of excess oxygen to permit efficient combustion of the particulate content of the trap, but to avoid rapid and damaging combustion rates. Actual engine air/fuel ratio is compared to a commanded air/fuel ratio, and the position of the backpressure valve is adjusted accordingly. The commanded air/fuel ratio is ratcheted upwardly or downwardly once in a predetermined time period in response to a temperature error signal between exhaust gas temperature sensed in the engine exhaust manifold and a predetermined commanded temperature. An override is provided to permit the vehicle operator to override regeneration when power is required from the engine, and a low power cut-off is provided to suspend regeneration when the engine is operated for a period of time at low power conditions where regeneration is inefficient.

Title: Pivoting multiple loop bipolar cutting device
Inventor: PARINS DAVID J
IPC: A61B17/32
Filed: 1992-07-22
Abstract: A PIVOTING MULTIPLE LOOP BIPOLAR CUTTING DEVICE   ABSTRACT OF THE DISCLOSURE    An electrosurgical cutting instrument with bipolar electrodes integrally formed into a pivoting ceramic working head.   The ceramic head is pivotable about a pivot point by selectively retracting a substantially rigid wire internal to a working element which is slidably and rotatably received within an introducer and connected to a point on the ceramic head offset from a longitudinal axis.  Radial incisions are induced into a prostate gland during a transurethral resectioning of the prostate gland (TURP) by applying an RF energy across the bipolar electrodes from an external power source and drawing the electrodes across prostate gland tissue.          The pivotal head can be selectively reciprocated to approximately a 90° angle relative to a longitudinal axis of the introducer to effectively cauterize tissue during surgery to perform resectioning of the prostate.   Increased maneuverability  of the instrument allows a surgeon to more quickly and effectively complete a TURP.          The electrodes may be formed in various shapes out of ductile tungsten alloy to withstand high operating temperatures depending upon the nature of the cutting desired.  The cutting instrument is suitable for other surgical procedures as well performed using an endoscope.

Title: Battery management system
Inventor: ALBRIGHT CHARLES D
IPC: H02J7/14
Filed: 1993-01-14
Abstract: BATTERY MANAGEMENT SYSTEMS                 ABSTRACT OF THE DISCLOSURE   A battery management system maintains a charge on at least one auxiliary battery by switching the auxiliary battery automatically into parallel with the main battery charging circuit or with the auxiliary load.  The system uses the AC component of the charging signal of a vehicle or boat charging system to trigger switching circuits coupled to operate relays or similar switching means which couple the auxiliary battery to the main charging circuit.  When no charging signal is present i.e., when the vehicle or boat engine is turned off, the auxiliary battery is switched automatically out of the charging system and is charged and in condition for use.  A delay circuit can be provided for providing non-shorting operation, especially for use with more than one auxiliary battery which batteries are charged in parallel and loaded in series, whereby the combined series voltage of the auxiliary batteries would exceed the vehicle or boat supply voltage.   The timing circuits open the circuit from the auxiliary batteries to the vehicle or boat charging system prior to switching the batteries into a series configuration for use with a load requiring a voltage higher than the rated voltage of the charging system.   The timing circuits thereby prevent momentary large currents upon changes of state.
