Title: Device for measuring a mass flow rate of a particulate material
Inventor: ZWEIFEL YVES
IPC: G01F1/86
Filed: 2006-01-27
Granted: 2012-12-18
Abstract: A device for measuring a mass flow rate of a flow of particulate material which moves in a predetermined direction. The device includes a weighing cell, a first apparatus, a second apparatus, and a third apparatus. The weighing cell includes a tubular wall and is disposed to be passed through by a flow of particulate material. The first apparatus weighs the weighing cell and the quantity of particulate material contained in the weighing cell and produces a first signal. The second apparatus measures the speed of flow of the particulate material which flows through the weighing cell and produces a second signal. The third apparatus calculates the bulk density of the particulate material, calculates the mass flow rate of particulate material which flows through the weighing cell, and produces a third signal representing the mass flow rate of particulate material which flows through the weighing cell.

Title: Blocked isocyanate crosslinker solution
Inventor: GARNER ARCHIE W
IPC: C08G18/80
Filed: 2004-12-10
Granted: 2010-10-12
Abstract: A low viscosity blocked isocyanate solution can be made by reacting together a polymeric isocyanato compound and propylene glycol, or a polymeric primary or secondary amine and propyl carbonate. The resulting beta-hydroxypropyl urethane polymer can be combined with propylene glycol monomethyl ether as a reducing solvent to form a pourable high-solids solution with good flow properties at room temperature. The solution has lower viscosity than is obtained using ethylene glycol as a blocking agent or using several non-HAPS  reducing solvents that are similar to propylene glycol monomethyl ether. The solution can readily be combined with electrodepositable paint ingredients to form a curable coating composition.

Abstract: An apparatus for sensing mis-alignment between an aircraft inertial reference frame and a reference frame of an attached sensor is disclosed. The apparatus includes a first laser mounted on the sensor and in the center of and normal to a first measuring surface; and, a second laser also mounted on the sensor perpendicular to the first laser and in the center of and normal to a second measuring surface. A first reflector is mounted to and aligned with the inertial reference frame of the aircraft and is disposed for reflecting a beam of light from the first laser, whereby misalignment in roll and yaw between the sensor and the aircraft is reflected on the first measuring surface. In a similar manner, a second reflector is mounted to and aligned with the inertial reference frame of the aircraft and perpendicular to the first reflector, and is disposed for reflecting a beam of light from the second laser, whereby misalignment in roll and pitch between the sensor and the aircraft is reflected on the second measuring surface. The misalignment bias may later be read manually or electronically, and then used by the aircraft's or sensor's computer system to compensate for the misalignment bias.

Granted: 2014-06-03
Abstract: Fiber Bragg gratings were written in pure silica photonic crystal fibers and photonic crystal fiber tapers with 125 fs, 800 nm IR radiation. High reflectivites were achieved with short exposure times in the tapers. Both multimode and single mode grating reflections were achieved in the fiber tapers. By tapering the photonic crystal fibers scattering that would otherwise have occurred was lessened and light external to the fiber could reach the core effectively to write a grating.

Title: Expandable flow control device
Inventor: BROOME JOHN T
IPC: E21B43/08
Filed: 2006-06-01
Granted: 2012-01-03
Abstract: The invention involves the use of a base pipe perforated only in a specific section under each screen section. Inflow comes through an outer shroud that is optional and goes through the screen material and into an annular space between the screen material and the imperforated base pipe. After traveling longitudinally in that annular space, the flow must go through a restriction that preferably comprises a porous media in a passage defined outside the still imperforated base pipe. After passing through the porous media in a particular screen section, the flow can pass through openings in the base pipe. A surrounding ring preferably protects the porous media during run in and expansion and can also optionally create additional resistance to flow to work in tandem with the porous media. Other flow restricting techniques in place of the porous media are contemplated.

Title: Systems and methods for audio processing
Inventor: WANG WEN
IPC: H04S1/00
Filed: 2006-09-13
Granted: 2015-12-22
Abstract: Systems and methods for audio signal processing are disclosed, where a discrete number of simple digital filters (266) are generated for particular portions of an audio frequency range. Studies have shown that certain frequency ranges are particularly important for human ears' location-discriminating capability, while other ranges are generally ignored. Head-Related Transfer Functions (HRTFs) (170) are examples response functions that characterize how ears perceive sound positioned at different locations. By selecting one or more "location-critical" portions (172, 174) of such response functions, one can construct simple filters (180) that can be used to simulate hearing where location-discriminating capability is substantially maintained.  Because the filters can be simple, they can be implemented in devices (550, 562) having limited computing power and resources to provide location-discrimination responses that form the basis for many desirable audio effects.

Abstract: An optoelectric angle-measuring device according to the invention has a code carrier having a position code (C1) which can be detected optically as well as a scanning device in the form of a light-sensitive row or area for detecting the position code (C1) and generating a position-dependent scanning signal. The scanning device which is in the form of a scanning film (F1), in particular, surrounds the code carrier or the code carrier essentially completely surrounds the scanning device along a circumference. This provides an extremely accurate angle-measuring device by virtue of the fact that a large part of the position code (C1), in particular even the entire position code (C1), can be detected.
