IPC: G05B17/02
Filed: 1997-05-02
Abstract: An industrial plant controller device's control algorithm is ported from a real-time proprietary operating environment (an industrial control plant) to a non-proprietary environment such as an ethernet running TCP/IP. In combination with an application programmer's interface, the invention allows manipulation of the actual device controller's control algorithms including the capability to arbitrarily stop and start the controller algorithm's operation, exercise the controller algorithm at a rate slower and faster than real-time, restore the controller algorithm to a known state, and store the configuration of the algorithm controller state. The increased fidelity provided by the invention allows an operator to design, test, and verify control system strategies in a more comprehensive manner than possible in prior art systems. An added benefit of the invention is that it can be used in an improved operator training system.

Title: Inhibition of nuclear transcription factor nf-kb by caffeic acid phenethyl ester (cape), derivatives of cape, capsaicin (8-methyl-n-vanillyl-6-nonenamide) and resiniferatoxin
Inventor: GRUNBERGER DEZIDER
IPC: C12N5/07
Filed: 1997-09-04
Abstract: Nuclear Factor NF-.kappa.B is a protein specific to B cells, binds to a specific DNA sequence within the immunoglobin light chain .kappa. locus enhancer region, and plays a central role in various responses, due to rapid induction of gene expression. NF-.kappa.B controls the expression of various inflammatory cytokines, the major histocompatibility complex genes, and adhesion molecules involved in tumor metastasis.  The present invention is drawn to the inhibition of activation of NF-.kappa.B  by caffeic acid phenethyl ester (CAPE) and two analogues of CAPE. Tumor necrosis factor (TNF) activation of NF-.kappa.B is completely blocked by CAPE in a dose- and time-dependent manner, as is activation by phorbol ester, ceramide, hydrogen peroxide, and okadaic acid.  Additionally, capsaicin (8-methyl-N-vanillyl-6-nonenamide) and resiniferatoxin inhibit the activation of NF-.kappa.B induced by different agents. Further, the present invention discloses methods for using these inhibitors in the treatment of pathological conditions caused by the activation of NF-.kappa.B, such as toxic shock, acute inflammatory conditions, acute phase response, atherosclerosis and cancer.

Patent CA-2274324-A1 (CA)
Inventor: GADKARI AVI
IPC: C08L23/12
Filed: 1999-06-10
Abstract: Random propylene thermoplastic copolymers can be used to increase the elongation to break and toughness of thermoplastic vulcanizates.  Semi-crystalline polypropylene is a preferred thermoplastic phase. The rubber can be olefinic rubbers. Random thermoplastic polypropylene copolymers are different from conventional Ziegler-Natta propylene copolymers as the compositional heterogeneity of the copolymer is greater with Ziegler-Natta copolymers. This difference results in substantial differences in properties (elongation to break and toughness) between thermoplastic vulcanizates modified with random thermoplastic propylene copolymers and those modified with conventional Ziegler-Natta propylene copolymers. An increase in elongation to break results in greater extensibility in the articles made from a thermoplastic vulcanizate.

Title: Adaptive frequency reuse plan
Inventor: HENSON STEVEN RAY
IPC: H04W16/24
Filed: 1998-02-06
Abstract: A cell pattern for use with a frequency reuse plan is disclosed. Seven clusters (5) each comprising N cells per cluster are grouped together as a modified cluster (40). Each cell is further divided into three sectors (70). The total number of available frequency channels are divided into a F times seven (F*7) number of groups. Frequency channels associated with a group are then assigned to each of the cells within the modified cluster. In order to increase call capacity within a particular sector, a frequency channel previously assigned to a corresponding sector within the same cell group is reused.      Within a continuing increase in channel re-usage within a particular modified cluster, the (N*7)/(F*7) reuse plan is gradually lowered to the original N/F reuse plan without re-configuring the frequency allocation throughout the network.

Patent CA-2285198-A1 (CA)
Title: Parallel transmission method
Inventor: SUZUKI YASUNORI
IPC: H04J11/00
Filed: 1999-01-07
Abstract: The intervals (120, 125) between the spectra (111, 112, 113) of carrier waves are greater than or around the coherent bandwidth, and hence the carrier waves can receive mutual correlative phasing.      Therefore, even if the spectrum (112) receives phasing by a specific carrier wave during call and consequently the line quality degrades, the call can be continued by the other spectra (111, 113). In this case, the other received signals are synchronously detected and combined by a maximum ratio composite method, and carriers can be regarded as independent of each other. Therefore, diversity reception by a maximum ratio composite method of branches, the number of which is equal to the number of carriers used for communication, is possible. Since the intervals between the frequencies are so set by using existing circuit techniques that the carriers are almost mutually in correlation, no radio circuit having frequency characteristics of wide band nor processor for high-degree digital signal processing is needed.

Filed: 1999-10-12
Abstract: To be able to successfully compensate the echos occurring- in bidirectional telecommunications systems, comprising for example 2-wire/4-wire converters and/or AD/DA converters and/or satellite transmission links, the echo coupling factor and echo delay time for a system must be determined with a very high degree of accuracy and independently of the double talk situation. For this purpose, in accordance with the invention a process is provided wherein, by analyzing a dialogue, states and time segments are determined in which the probability of an incorrect evaluation of the coupling factor between the transmission paths and the echo delay time is very low. To improve the measurement accuracy, auxiliary quantities dependent upon the speech dynamics and the characteristic curve of the speech signal are introduced.

Filed: 1998-04-20
Abstract: A poultry processing machine is provided which automatically vents and opens the poultry, eviscerates the poultry, displays the poultry for inspection, and either provides a normal or radical clean out procedure to the poultry. When the poultry is being physically processed, it is maintained in a generally stationary position with respect to the surface supporting the poultry processor to provide for uniform positioning of the poultry on the conveyor.  Further, the poultry is positioned in a generally horizontal position during the venting and opening, eviscerating and cleaning procedures, to facilitate removing the unwanted materials from the poultry without increasing the risk of contamination. The eviscerating station uses an eviscerating tool which includes an opening sized to receive the viscera package therethrough during the eviscerating process to prevent damage to the viscera package. The clean out station automatically recognizes whether a particular poultry is to receive the normal or radical clean out procedure, thereby reducing processing time.

Abstract: A power system for an electric motor drive such as may be used in an electrically propelled vehicle incorporates the combination of a high power density battery and a high energy density battery to provide an optimal combination of high energy and high power, i.e., a hybrid battery system. The hybrid battery system in one form includes components which prevent electrical recharge energy from being applied to the high energy density battery while capturing regenerative energy in the high power density battery so as to increase an electric vehicle's range for a given amount of stored energy. A dynamic retarding function for absorbing electrical regenerative energy is used during significant vehicle deceleration and while holding speed on down-hill grades, to minimize mechanical brake wear and limit excessive voltage on the battery and power electronic control devices. The high energy density battery coupled in circuit with a boost converter, a high power density battery, a dynamic retarder, and an AC motor drive circuit. The hybrid battery system is controlled by a hybrid power source controller which receives signals from a vehicle system controller using current and voltage sensors to provide feedback parameters for the closed-loop hybrid battery control functions.
