IPC: H04W52/04
Filed: 1995-05-10
Abstract: A transmission power control method for a CDMA system including the steps of calculating an actual SIR (Signal-to-Interference Ratio) of a desired signal; deciding whether the actual SIR is greater than a predetermined reference SIR which satisfies a predetermined communication quality; forming a transmission power control bit on the basis of a result of deciding; inserting the transmission power control bit periodically into a forward frame, which steps are performed at the base station, and steps of calculating tentative reverse transmission power in accordance with the transmission power control bit in the forward frame; deciding reverse transmission power such that the reverse transmission power is made equal to the tentative reverse transmission power when the tentative reverse transmission power is less than a predetermined maximum transmission power, but otherwise made equal to the predetermined maximum transmission power; and transmitting a signal from the mobile station to the base station at the reverse transmission power, which steps are performed at the mobile station. This makes it possible to prevent the transmission power from diverging to the maximum output of a transmitter power amplifier.

Title: Peak current detection in a test instrument for ensuring validity of component test output
Inventor: GIBSON ROBERT T
IPC: G01D1/12
Filed: 1995-09-01
Abstract: Methods and apparatus are disclosed for using current detection in a test instrument to ensure validity of component test output. In a component test instrument that employs digital synthesis of a test stimulus waveform, voltage scan data and current scan data are successively acquired, the scan data being synchronized relative to the test stimulus waveform. The voltage and current scan data are stored in respective temporary storage buffers. Before displaying the data, a check for an open lead is conducted in a manner similar to a currentscan. A zero current value indicates an open lead and the acquired scan data is disqualified from being displayed. Similarly, at the beginning of a component test operation, an open lead test is performed and the first voltage scan is deferred until a validity check confirms that the test leads or probes are in place. The disclosed methods and apparatus ensure that only valid data is displayed to the user.

Title: Glycolipids for serodiagnosis of tuberculosis and leprosy
Inventor: LASZLO ADALBERT
IPC: G01N33/569
Filed: 1995-09-01
Abstract: A Dot-Blot assay ("spot test") with Bis-N,N,dioctadecylamide (BDA.TDA) as antigen was developed to detect anti-BDA.TDA antibodies in tuberculosis patients.  To develop the antigen-antibody reaction, as a first step and in order to enhance the reaction, an anti-human rabbit serum was used followed by incubation with a protein A-colloidal gold conjugate.  This assay showed almost equal sensitivity and specificity as the .beta.-galactosidase ELISA test which was conducted in parrallel.  This simple and fast assay could be used in places where ELISA equipment is not easily available.

Title: Chimeric cytokine receptors in lymphocytes
Inventor: GREENBERG PHILIP D
IPC: C12P21/02
Filed: 1994-04-06
Abstract: Recombinant polynucleotides are provided that encode chimeric cytokine receptors. The chimeric receptor is comprised of an extracellular domain derived from cytokine receptor A-R that binds cytokine A, fused to a transmembrane and cytoplasmic domain derived from cytokine receptor B-R that binds cytokine B. The figure depicts a chimeric receptor with a GM:GSF receptor extracellular domain fused to an IL 2 receptor transmembrane and cytoplasmic domain. When the chimeric receptor is expressed in a lymphocyte it lessens the growth dependency of the lymphocyte on cytokine B in the presence of cytokine A.

Title: Plasma-enhanced vacuum drying
Inventor: SPENCER ROBERT M
IPC: F26B5/04
Filed: 1995-10-10
Abstract: A plasma-enhanced vacuum drying method is disclosed. It is advantageously applied in plasma sterilization processes in particular, and represents a significant improvement for general evacuation drying methods. Articles to be sterilized are placed in a sealed chamber and the chamber is evacuated. A plasma of residual gas species is generated in the chamber during an initial evacuation step. This promotes drying of the articles and advantageously allows a desired pressure to be attained more quickly than without the plasma. Sterilizing gas is injected into the chamber, and a second plasma is generated to activate the sterilizing gas plasma, thereby sterilizing the articles in the chamber.

IPC: A01K97/11
Filed: 1995-11-23
Abstract: A fishing jig is disclosed for holding a fishing rod and moving the rod in an upand down motion in an oscillating manner. The rod is oscillated by means of an electric motor that drives a jigging wheel and lever arrangement via a gear assembly which is connected to the jigging wheel. Both the rate of oscillation and oscillation stroke may be varied. Upon a strike by a fish, the jig has a mechanism for quickly raising the rod in an upward direction with sufficient force to set the hook. The distance that the rod travels to set the hook also may be adjusted. In addition, the sensitivity of the jig can be adjusted with regard to both the amount of force that must be exerted upon the fishing rod holder as a result of a fish strike and the degree of travel which the rod holder must undergo, as a result of a fish strike to activate the hook set mechanism. The jig may also be coupled to an alarm that indicates activation of the hook set mechanism.

IPC: F04D29/36
Filed: 1996-05-23
Abstract: A variable pitch propeller has a two part hub assembly, each part of the hub has generally semi-cylindrical half sockets formed therein for receiving the cylindrical blade root shanks of individual fan blades. The sockets have enlarged portions, defining semi-annular shoulders, which receive an enlarged portion of the blade root shank so as to prevent axial movement of the fan blade. The half sockets of at least one part of the hub further have recessed portions for receiving locking insert members having a curved upper surface and a longitudinal keyway formed therein. A radially projecting key extends longitudinally along at least an a portion of the blade root shank and fits into the keyway formed in the locking insert member when the fan blade is placed into the half socket containing the locking insert member. The two parts of the hub assembly are coupled to clamp the fan blades within the aligned half sockets. With the key of the root shank disposed in the keyway of the locking insert member, pitch-wise rotation of the blade is prevented, the orientation of the keyway in the locking insert defining the pitch angle of the blade.
