Title: Digital processor sensor loop detector and method
Inventor: WALLACE JACK BRUCE
IPC: B65G43/02
Filed: 2007-05-22
Granted: 2014-10-21
Abstract: A digital processor for use in a conveyor belt rip detector, which provides excitation signals at a selected frequency to inverted and noninverted sensor loops on a conveyor belt and then, detects corresponding received signals from the sensor loops. The digital processor then performs FFTs on the corresponding received signals to provide respective received signal frequency spectrums. Next magnitude and phase values of the selected frequency in the respective received signal frequency spectrums are used to determine a qualitative state of the sensor loops. The selected frequency has a lowest detected ambient noise level, and the magnitude value is a normalized magnitude value.

Abstract: A method and apparatus for conditioning imported liquefied natural gas to conform to a particular pipeline heating value specification and recovery of liquefied petroleum gas or natural gas liquids from liquefied natural gas are disclosed. An input stream containing liquefied natural gas is split into a direct stream and a bypass stream. The direct stream is heated in a cross-exchanger to produce a heated rich liquefied natural gas stream, which is split into a primary column feed and a secondary column feed. At least a major portion of the secondary column feed is vaporized to produce a vaporized secondary column feed, which is expanded in an expander to produce a vaporized and expanded secondary column feed. A top feed, the primary column feed, and the vaporized and expanded secondary column feed are fractionated to produce an overhead product stream and a bottom product stream. The overhead product stream is compressed in a compressor coupled to the expander. At least a major portion of the compressed overhead product stream is condensed by cooling in the cross- exchanger to produce a compressed and condensed overhead product stream. A reflux stream of at least one of the compressed and condensed overhead product stream or an output stream is directed to a top of the fractionation unit as the top feed. The bypass stream is mixed with a balance stream of the compressed and condensed overhead product stream to produce the output stream, which is vaporized to produce a conditioned natural gas product.

Abstract: The present invention is a thermosetting bismaleimide resin system comprising a liquid phase and a solid phase where the non-crystallizing liquid phase contains the curing agents diallyl ether of a substantially aromatic radical and a bis(alkenylphenoxy) ether of a substantially aromatic radical along with a substantially aromatic bismaleimide as a particle slurry and optionally a free radical inhibitor. The curing agents are non-crystallizing compositions for use in bismaleimide resin formulations to increase the thermal durability of a cured resin composite as shown by reduced microcracking as measured by reduced weight loss after thermal aging. The present invention resists microcracking over bismaleimide resin systems which incorporate other curing agents or combinations of curing agents. The present invention further provides a bismaleimide resin formulation suitable to make prepregs with reduced crystallization for reduced viscosity supporting improved manufacturing properties and improved tack.

Abstract: A system and method for deploying balloon-expandable (i.e., plastically-expandable) prosthetic heart valves (20) so that they assumed their desired operational shape. The system includes a balloon (40) that accommodates non-uniform expansion resistance in the heart valve to expanded to its desired tubular or other shape. The heart valve may have substantially more structural elements adjacent one end, typically the inflow end (22), and the balloon is tapered so as to expand the inflow end before the outflow so that the valve ends up in a tubular shape. Alternatively, a stepped balloon with a larger diameter proximal section adjacent the inflow end of the valve may be used. A method includes applying a non-linear expansion forced to the interior of a plastically- expandable prosthetic heart valve to overcome areas of greater resistance to expansion and result in uniform expansion.

Title: Correction of amplitude and phase imbalance in psk receivers
Inventor: OZLUTURK FATIH M
IPC: H04L27/22
Filed: 1999-12-07
Granted: 2011-07-12
Abstract: The present invention balances the amplitude and phase of a received QPSK signal that may have been corrupted during transmission. The system determines the amplitude of the I and Q symbols of a received signal, compares them, and applies a correction to one or both channels to correct for amplitude imbalance. For phase imbalance, the system calculates the cross-correlation of the I and Q symbols which should average to zero. A correction factor is derived from the cross--correlation and applied to both channels, returning the phase cross-correlation to zero. The output from the system is a signal corrected in both amplitude and phase.

Abstract: The invention relates to the discovery of a human endogenous retrovirus (HERV) family, Type I HERV-K (HML-2) which appear to be active in vitro and in vivo, infectious, and which have the have the salient features and properties of foamy retroviruses. Based on its natural replication in humans, and that it protects the host from viral and tumor transformation, this non-pathogenic endogenous virus could be developed as a replication competent gene therapy vector. It also is expected to have much higher efficacy than other vectors as it crosses the bloodbrain barrier and infects almost all cell types in the host (proliferating or not). It may naturally lyse tumor cells or infected cells, and thus could even be used without genetic modification. Of course, this vector could be used in traditional ways with it ability to replicate genetically removed. In addition to its value as a vector, as it is reactivated with infection, its detection could also be used to monitor the safety of gene therapy (irrespective of vector type used), as well as other biological therapies including vaccination, blood transfusion, transplantation and xenotransplantation. Finally it may be used to screen for new therapeutic and prophylactic treatments for a wide variety of diseases.
