Title: Apparatus for the intermittent storage and controlled feeding of volatile gasoline components into the intake manifold of an internal combustion engine
Inventor: BUCHALLA HARALD
IPC: F02M25/08
Filed: 1992-01-06
Granted: 1999-06-08
Abstract: Apparatus for the intermittent storage and controlled feeding of volatile fuel components present in an unfilled space of a fuel tank into the intake manifold of an internal combustion engine, having a vent conduit which extends between the unfilled space and the intake manifold, includes an absorption element and is closable by a servo-valve positioned in series after the absorption element.  The vent conduit is further provided with a first sensor which is positioned in series before the absorption element and detects a gas flow through the vent conduit.  A vacuum actuated valve which is positioned in series before the servo-valve is provided with a second sensor which detects its actuation.  The first and second sensors are connected for signal transmission with a diagnosis block which compares the two signals of the sensors for error diagnosis with a servo-valve control signal.  With the apparatus, a controlled feeding of the fuel volatiles is achievable without using complex sensory systems in addition to the sensors already used in the control of the operating conditions of the internal combustion engine.

Title: Method and apparatus for preventing motoring while braking
Inventor: BACKSTRAND JON E
IPC: B66C13/22
Filed: 1992-11-06
Granted: 1996-12-10
Abstract: The inventive method and machine are improvements in aspects of a material handling machine (such as an overhead travelling crane) having an electrically-powered traverse drive, e.g., a bridge drive.  Such machine has (a) regenerative motor braking and (b) a manually-applied hydraulic brake, both for retarding the machine.  The invention prevents the bridge drive motor from "driving through the brake" when the hydraulic brake is being applied to result in significant retarding torque.  When the hydraulic brake is pedal-applied, an electrical contact closes at a predetermined hydraulic pressure and other devices, relays and the like, are actuated to modify operation of the controller and prevent "motoring" simultaneous with hydraulic braking.   Regenerative braking is likely to be set for a retardation rate less than results from application of the hydraulic brake. The invention prevents the drive motor and hydraulic braking system from "fighting."  With the invention, the motor control unit is disabled at some predetermined pressure in the brake hydraulic line.  Thereafter, the machine is retarded solely by application of the manually-operated brake until the machine reaches a very slow speed.

Title: Sensor probe for measuring hydrogen concentration in molten metal and method for measuring hydrogen concentration
Inventor: KOIDE KUNIHIRO
IPC: G01N27/30
Filed: 1992-11-26
Granted: 1996-09-03
Abstract: On the inner surface of sensor element made of proton conductive solid electrolyte with perovskite structure and enclosed at its lower end, a reference electrode constituted of porous electrode is formed, and a measuring electrode constituted of porous electrode is formed on the outer surface thereof.  And, the reference electrode and the measuring electrode are gas-tightly separated by sealing material.  The sensor prove is inserted into ceramic sensor holding cup and both are fixed in such a way that a part of the measuring electrode extrude into said holding cup.  Then, by dipping the holder into molten metal by facing its opening part downwards, a space contacting with molten metal is enclosed in the holding cup.     Thereby, reduction of solid electrolyte constituting the sensor element can be prevented, and hydrogen concentration in molten metal can be accurately measured without direct dipping the sensor element into molten metal.  Thereby, it is possible to provide a sensor probe and a method for measuring hydrogen concentration in which hydrogen concentration can be continuously measured for long period and an apparatus with smaller size can be made.

Title: Dispersion compensating devices and systems
Inventor: ANTOS ANTHONY JOSEPH
IPC: G02B6/02
Filed: 1992-12-01
Granted: 2005-01-25
Abstract: Disclosed is a family of dispersion compensating optical fibers that are adapted for use with conventional single-mode transmission fibers that are optimized for zero dispersion operation at a wavelength in the range from 1290 nm to 1330 nm to form a transmission link suitable for low dispersion operation in the 1520-1565 nm wavelength window.      The dispersion compensating fibers are capable of providing a dispersion more negative than -20 ps/nm-km and attenuation less than 1 dB/km at wavelengths in the 1520-1565 nm region.      Certain of the dispersion compensating fibers also exhibit a dispersion versus wavelength relationship having a negative slope in the 1520-1565 nm region, to compensate for the dispersion versus wavelength slope of the trandsmission fiber. The dispersion compensating fiber can be advantageously combined with a fiber amplifier to form a compensator that is adapted to overcome attenuation introduced into the system by the dispersion compensating fiber. In one embodiment, the dispersion compensating fiber is also a distributed fiber amplifier.

Abstract: A shirred casing article is composed of a cut length of fibrous casing and must be soaked prior to stuffing.  A loop is attached at one end of the cut length for hanging the casing after stuffing. However prior to stuffing, the loop is extended longitudinally about the shirred casing article to maintain the integrity of the shirred casing during soaking. Thus the loop which functions as a means to suspend the casing after stuffing, functions before stuffing as a means to restrain longitudinal expansion of the shirred article.

Title: Folding machine
Inventor: FISK DWIGHT R

Filed: 1993-12-14
Granted: 2002-09-03
Abstract: A folding machine includes a vacuum conveyor and a plurality of flip folders spaced along the length of the conveyor. A length of sheet material is fed down from the conveyor to position the lead end of the sheet in clamp members at a first flip fold. The end is clamped and rotated downstream and up above the remainder of the sheet which is continuously fed down the conveyor. The clamps are released to allow the lead end to fall over the trailing edge of the sheet, thereby completing a first fold which reduces the length of the sheet 50 percent. Successive lead ends of the sheet are folded by second and third flip folders to reduce the length of the sheet to 1/8 the length of the original sheet and increase the thickness of the sheet to eight plies. The final folded bundle is fed to a tuck folder which further reduces the length of the package 50 percent forming a folded package 1/16 the length of the original sheet and having 16 plies.

Title: Removing waste ink from capping station
Inventor: DIETL STEVEN J
IPC: B41J2/165
Filed: 1994-06-06
Granted: 1998-08-18
Abstract: A process and apparatus for removing waste ink from a capping station on a low cost integral capping, priming and wiping station for a thermal ink jet printer. In particular, the prime operation is repeated so that the scanning carriage (containing the ink jet printhead) travels past the capping position which breaks the vacuum seal and causes waste ink in the cap volume to be released into the pump chamber, thus cleaning the cap volume of excess ink. The additional prime cycle does not remove ink from printhead orifices because the scanning carriage travels away from the capping position as vacuum is applied.

Filed: 1994-06-20
Granted: 1998-10-13
Abstract: A compression/decompression method for image data allows addition of a code amount control amount in units of data of one block without necessitating an excessive header capacity.  In compression, a quantization conversion coefficient of a quantization conversion coefficient set is replaced with a code amount control amount, and a resulted quantization conversion coefficient set is coded, whereafter a quantization coefficient of a quantization coefficient set corresponding to the code amount control amount of the quantization conversion coefficient set is changed to 0.  In decompression, the quantization coefficient set is extracted, and coded data are decoded in units of data of one block.  Then, the code amount control amount is extracted from the quantization conversion coefficient set of the decoded data.
