Title: Inhibition of mammalian muscle wasting and protein degradation by tetracyclines
Inventor: MAIMON JONATHON
IPC: A61P21/00
Filed: 1991-06-27
Granted: 2003-05-13
Abstract: A method for treating mammals suffering from skeletal muscle wasting and/or intracellular protein degradation of skeletal muscle systems by administering to the mammal an amount of tetracycline which results in a significant reduction of the muscle wasting and protein degradation is disclosed. In addition, there is also disclosed a method of increasing the protein content of skeletal muscle systems of mammals by administration of tetracyclines. The tetracyclines useful in the above methods are both antimicrobial and non-antimicrobial. In a preferred embodiment, the method of treatment utilizes a non-antimicrobial tetracycline such as dedimethylamino-tetracycline (CMT).

Title: Seat back return resilient device
Inventor: CILLIERE FRANCOIS
IPC: A47C1/024
Filed: 1991-07-29
Granted: 1996-04-23
Abstract: A resilient back return device used in two-door vehicles is provided. Between the mobile flange of the articulation and the fixed flange of the same articula-tion a connection rod is pivotably mounted to the sit-ting portion flange, whereby the connection rod is connected by a small helical spring to the mobile flange of the seat back so that, when the seat back is lowered over the sitting portion, the spring is in an unstressed state while the spring is normally under tension when the seat back occupies an intermediate position and is sufficiently stressed when the seat back is placed in the prolongation of the sitting portion to form a berth, the spring then occupying a position in which it is sufficiently powerful to move up the seat back from the seat. Due to its fixation points, a spring of small volume and a short elongation but with a very high pulling force is used.

Title: Nucleic acid amplification with dna-dependent rna polymerase activity of rna replicases
Inventor: DIMOND RANDALL L
IPC: C12Q1/68
Filed: 1991-12-31
Granted: 2003-07-08
Abstract: The present invention entails methods, and kits for carrying them out, based on the discovery that an RNA replicase, such as Q.beta. replicase, has DNA-dependent RNA polymerase ("DDRP") activity with nucleic acid segments, including DNA segments and DNA:RNA chimeric segments, which comprise a 2'-deoxyribonucleotide and which have sequences of RNAs that are autocatalytically replicatable by the replicase. The discovery of this DDRP activity provides methods of the invention for nucleic acid amplification wherein a nucleic acid, with a DNA segment with the sequence of an RNA that is autocatalytically replicatable by an RNA replicase, is provided as a substrate for the replicase. The replicase catalyzes synthesis, from the DNA segment, of the RNA, which the replicase then autocatalytically replicates. The invention entails use of the amplification methods in detecting nucleic acid analytes, as in nucleic acid probe hybridization assays.      Such assays of the invention include those wherein a nucleic acid analyte is hybridized with one or more nucleic acid probes, which include or are processed to generate a DNA segment which is amplifiable through production from the segment, catalyzed by the DDRP activity of an RNA replicase, of an autocatalytically replicatable RNA, which is autocatalytically replicated to provide an abundance of readily detectable reporter molecules.

Patent CA-2088459-C (CA)
Title: System for optically transmitting digital communications over an optical fiber with dispersion at the operating wavelength
Inventor: WEDDING BERTHOLD
IPC: H04B10/2513
Filed: 1993-01-29
Granted: 2000-08-08
Abstract: When digital signals are transmitted over optical fibers (3), which have a considerable chromatic dispersion at the wavelength being used, the length of the transmission path is very limited when the digital signal to be transmitted is converted into an optical signal by means of intensity modulation. If frequency modulation (also called FSK = Frequency Shift Keying) is used instead of the intensity modulation, the bridgeable path can be greatly increased, but requires a suitable optical receiver at the receiving end. The invention utilizes a simple optical receiver (4), which is not sensitive to frequency modulation, but to intensity modulation. This is possible, because an intensity variation is created, due to the chromatic dispersion of the optical fiber (3) and the resulting running time differences of signal portions at different wavelengths (.lambda.0, .lambda.1) from the initial frequency modulation during the transmission over the optical fiber (3), which process is contained in the digital signal.

Abstract: An apparatus and method for automatically adjusting the control parameters of a self tuning controller used to regulate a process having a measured process variable signal. Using the measured process variable signal, an error signal representing a closed-loop response of the process to an upset condition is generated. Local extrema of the error signal is measured and three successive amplitude values are selected to produce measured decay and overshoot characteristics of the error signal. The three successive amplitude values are selected such that the measured decay characteristic is greater than the overshoot characteristic. Based on the measured decay and overshoot characteristics at least one of the control parameters of the controller is automatically adjusted to improve the difference between one of the measured characteristics and a target characteristic.
