Patent CA-2377280-C (CA)
Title: Fuel and oil system for a gas turbine
Inventor: RAGO GIUSSEPPE
IPC: F02C7/22
Filed: 2000-06-21
Granted: 2008-09-30
Abstract: The invention relates to an oil pump driven by a hydraulic motor, that is itself driven by fuel pumped by a remote fuel pump through the engine fuel line. The hydraulic fuel driven oil pump is particularly advantageous for use in a gas turbine engine, to reduce dependence on or completely eliminate the auxiliary gear box (AGB) conventionally used to mechanically connect various engine systems with an engine shaft. Separating the oil pump and other fuel/oil system components from the AGB enables the rationalization of these systems and allows designers to reconfigure systems into a compact unit including the oil pump, separator, oil tank, heat exchanger and filters for fuel and oil. Using pressurized fuel to hydraulically drive the oil pump frees the oil system from location restraints and operating limitations, and permits recovery of otherwise wasted energy from the fuel bypass circuit during idling and takeoff. The close correlation between fuel flow and oil requirements eliminates the energy waste in conventional system which pump oil at rates dependant on the speed of the AGB and engine rotation.

Granted: 2005-03-01
Abstract: An adaptive controller generates a sequence of dither signals for each of a plurality of control parameters. Each dither signal sequence is uncorrelated with every other dither signal sequence. Each nominal control signal has the first of its respective dither signal values simultaneously summed with it to form the control parameter values used by the controller. Updated control signals are applied in parallel to the controller outputs and a performance measure is taken and stored.  The second signals in the dither control sequences are then summed with their respective nominal controls and applied in parallel to the controller and a second performance measure is taken and stored. This process is repeated for the length of the dither control signal sequence to yield a sequence of performance measurements. The sequence of performance measurements is correlated with each of the dither sequences, forming sequences of correlator outputs, one for each control signal. Each correlator output sequence is integrated and, depending upon the value of a correlator's integration output, the corresponding nominal signal has it's dither value added to or subtracted from it to form the respective, updated control values.

Title: Ex-vivo priming for generating cytotoxic t lymphocytes specific for non-tumor antigens to treat autoimmune and allergic disease
Inventor: CAI ZELING
IPC: A61K35/12
Filed: 2002-05-13
Granted: 2014-07-08
Abstract: Cytotoxic T lymphocytes (CTLs specific for antigenic peptides derived from IgE molecule can be generated in vitro by stimulating resting naïve CD8 T celles with IgE peptides presented by artificial antigen presenting cells. The IgE specific CTLs lyse the target cells loaded with IgE peptides in vitro and inhibit antigen specific IgE response in vivo. In addition, adoptive transfer of the IgE specific CTL to an asthmatic mouse model can inhibit the development of lung inflammation and airway hypersensitivity. IgE specific CTL provides a treatment for allergic asthma and other IgE-mediated allergic diseases. Antigenic peptides identified from non-tumor self-antigens induce specific cytotoxic T lymphocyte (CTL) in vitro. The CTL induced by peptides identified from CD40L can kill activated CD4 T cells. In vitro generated CTL specific for CD40L inhibit CD4-dependent antibody responses of all isotypes in vivo. In contrast, CTL induced by antigenic peptides derived from IgE specifically inhibit IgE responses, and adoptive transfer of CD40L-specific CTL to NOD mice at early age delay the adoptive transfer of CD40L-specific CTL to NOD mice at early age delay the development of diabetes in NOD mice. In vitro generated CTl specific for non-tumor sel-antigens expressed on activated CD4 T cells regulate immune responses in vivo.

Abstract: Equalizing method and apparatus for single carrier system having an improved equalization performance is disclosed, which includes: a section setting unit for setting filter taps having a predetermined section corresponding to the predicted multi-path; a repeat setting unit for setting filter taps of a repetition section by making the set predetermined section repetitive periodically; and a filter unit for filtering the multi-path by updating the coefficients of the filter taps of the set repetition section. The repeat setting unit sets the filter taps of the repetition section corresponding to an operation characteristic of the filter unit. Accordingly, the apparatus can improve equalization performance by setting filter taps corresponding to the predicted multi-path and updating only the set coefficients of the filter taps. Further, the apparatus can improve equalization performance in dynamic channel circumstances in which the multi-path changes.

Title: Alkylation of saturated hydrocarbons using interstage distillation
Inventor: NAT PIETER JAN
IPC: C07B61/00
Filed: 2003-03-06
Granted: 2011-05-10
Abstract: A process for the alkylation of saturated hydrocarbons by reacting an alkylatable compound with an alkylation agent to form a product stream comprising alkylate. The process involves the use of a series of at least two reactors. During the process, the product stream is subjected to an interstage distillation step, thereby removing at least a portion of the alkylate from the product stream before the product stream is introduced into a downstream reactor. In this process the alkylate concentration is kept at a relatively low level, thereby minimising the amount of undesired by-products that can be formed by, e.g., degradation of alkylate and condensation of degradation products.
