Granted: 2000-09-19
Abstract: The substitution of the L-Pro at the 7-position with D-Phe or D-Tic and substitution of the L-Phe at the 8-position with hydroxyproline ethers and thioethers of the peptide hormone bradykinin and other additional substituted analogs of bradykinin converts bradykinin agonists into bradykinin antagonists. The invention further provides additional modifications at other positions within the novel 7- and 8-position modified bradykinin antagonists, which increase enzyme resistance, antagonist potency, and/or specificity of the new bradykinin antagonists. The analogs produced are useful in treating conditions and diseases of a mammal and human in which an excess of bradykinin or related kinins are produced or injected as by insect bites.

Abstract: Attenuation of an optical fiber is measured by transmitting an optical signal having a predetermined wavelength to the fiber, and FSK modulating the optical signal with information identifying the wavelength and transmitted power of the optical signal. At a receiver, the optical signal is detected and the information is recovered by demodulation. Wavelength-dependent sensitivity information for the detector is read from a store in dependence upon the wavelength information and used to control the gain of an amplifier for amplifying a subsequently transmitted continuous wave optical signal used for attenuation measurement. The received power level of this optical signal is converted into a digital value and used with the transmitted power information to determine the fiber attenuation at the predetermined wavelength. Reference power levels are determined by connecting a jumper between a port and an external detector. Measurement of attenuation and communication data over the fiber under test may be effected using two transceiver units, one at each end of the fiber. In addition to the external detector, each unit has an internal detector and sources connected to a port which is connected to the fiber under test by a jumper. Determination of the attenuation of the fiber then takes account of the loss of each fiber using reference power levels determined by initial calibration measurements.

Abstract: The present invention aims to shorten an aspiration time, when aspirating a red blood cell component of a liquid sample having high viscosity.   When aspirating the red blood cell component of a blood sample through a nozzle tip, a piston is pulled at its maximum to produce a maximum aspirating force, and starts aspiration. When a pressure in an aspirating system becomes equal to a predetermined value .alpha., the piston is returned to a position in which only a necessary aspiration volume of the liquid sample can be aspirated. Since the maximum aspirating force of the pump is utilized during the aspiration, the aspirating operation can be carried out more quickly.

Abstract: Disclosed  is  a  perforator  blade  for  core  wound  paper products, such as toilet tissue and paper towels.  The perforator blade has a relatively narrow notch width and a relatively narrow tooth width.  As the notch width and tooth width of the perforator blade are decreased, the total notch width, which is the aggregate of  the  width  of  each  notch  across  the  total  width  of  the perforator blade, is similarly decreased.     A  perforator  blade  according  to  the  present  invention provides   very   high   perforation   bond strengths,   joining superimposed  plies  in  face-to-face  relation,  without unduly increasing the tensile strength of the lands bridging adjacent sheets of the core wound paper product.  Also,  individual  tooth flexibility  is  increased  according  to  the  present  invention resulting in enhanced perforator blade life and perforation bond quality.   Perforated  paper  products  according  to  the  present invention  also  exhibit  less  lint,  reducing  hygiene  problems, reduced  occurrences  of  sheet  tearing  during  dispensing,  and provide a smoother, better finished appearance during dispensing.

Title: A circuit board arrangement including shielding grids, and constructing thereof
Inventor: SUSKI EDWARD D
IPC: H01P3/08
Filed: 1994-02-01
Granted: 2005-04-26
Abstract: A shielded flexible cable includes a first shielding grid having conductive elements formed as squares. A second shielding grid is also formed as squares. The two shielding gilds are positioned with respect to each other so that the vertices of the squares of the two grids are respectively offset from each other in each of two directions by one-half the diagonal distance between the vertices of the squares. Electrical signal conductors are positioned between the two grids along lines extending between the vertices of the squares to maintain a controlled impedance of the signal lines. A circuit board includes a reference plane configured as a grid having conductive elements formed as squares. Electrical signal conductors are positioned in a plane adjacent said grid. The decreased percent copper used to construct the grid increases the characteristic impedance of the signal conductors without increasing the thickness of the circuit board, without decreasing the width or thickness of the conductors and without using nonhomogeneous or nonstandard dielectrics. The circuit board provides the use of an increased range of impedance in signal conductors that permits the transfer of signals without degradation of the signal quality or loss of signal density, while providing an acceptable shielding capability.

Abstract: A battery system for supplying electric energy from a primary battery or a secondary battery to a load.  This system includes a battery consisting of the primary battery or the secondary battery, an electric double layer capacitor for storing electric energy from the battery, a limiting resistor for limiting the electric energy supplied from the battery to the electric double layer capacitor, and a discharge controller for controlling the electric double layer capacitor.  The discharge controller causes the elec-tric double layer capacitor to discharge the electric energy to the load intermittently in predetermined cycles while charging the electric double layer capaci-tor.  A discharging time for discharging the electric energy from the electric double layer capacitor to the load is shorter than a charging time for charging the electric double layer capacitor with electric energy.          At this time, a discharge current is greater than a charge current.

Abstract: Procédé de formation d'un composite en métal dur fritté dans lequel des nodules non frittés d'une poudre de métal dur prémélangée d'une première qualité sont dispersés uniformément dans des nodules non frittés d'un composite en métal dur prémélangé d'une seconde qualité. Les poudres de métal dur prémélangées forment un mélange poudreux composite qui est ensuite pressé et fritté pour former ledit composite en métal dur allié par dispersion. Une quantité suffisante de lubrifiant de pressage est ajoutée à l'une des poudres de métal dur prémélangées si bien que chacune des poudres de métal dur rétrécit au même degré environ par rapport à l'application de pression pendant le processus de compactage. Le lubrifiant de pressage est ajouté à la poudre de métal dur qui rétrécit le plus pendant le frittage. Grâce au rétrécissement uniforme des poudres des deux qualités, la migration du liant du constituant d'une qualité au constituant de l'autre qualité est réduite au minimum, ce qui permet d'obtenir un mélange poudreux composite à qualités supérieures parce que chaque constituant d'une qualité donnée conserve ses propres caractéristiques. En outre, le rétrécissement uniforme des poudres constituantes empêche les irrégularités de surface de la surface frittée.
