Title: Impedance arrangement for limiting transients
Inventor: O'LEARY RAYMOND P
IPC: H01H33/16
Filed: 1988-04-26
Granted: 1992-10-06
Abstract: ABSTRACT An impedance arrangement is provided for use in a high-voltage circuit. For example, the impedance arrangement is useful in a circuit which includes reactance elements and a high-voltage circuit-switching device. The impedance arrangement limits transient inrush current and/or voltages in a first frequency range which occur in the circuit during closure of the circuit-switching device and damps transients in a second frequency range which occur in the circuit during opening of the circuit-switching device. The impedance arrangement is also useful in applica-tions requiring tuning reactors and current-limiting reactors to limit abnormal power-frequency currents, harmonics, transients, and/or high-frequency inrush currents. The impedance arrangement functions predominantly as an inductive impedance over a first frequency range; e.g., corresponding to the frequencies of transients encountered during the closing of a circuit-switching device. Additionally, the impedance arrangement functions predominantly as a resistance over a second frequency range which is higher than the first frequency range; e.g., corresponding to the frequencies of transient conditions on a power system such as are encountered during the opening of the circuit-switching device. The impedance arrangement comprises a first winding having a first predetermined inductance and a second winding connected in parallel with the first winding. The second winding has a second pre-determined inductance and a second predetermined resistance. The second winding is wound with respect to the first winding in an opposite sense to the first winding and so as to define a predetermined mutual inductance between the first and second inductances.

Granted: 1991-11-05
Abstract: ABSTRACT OF THE DISCLOSURE The present invention is a manufacturing method of a rigid or semi-rigid foamed material which comprises a foaming process to make a practically thermoplastic foamed material wherein isocyanate component is reacted with polyol component in the presence of organic foaming agent and/or water in a condition that an excess quantity of the isocyanate component than the stoichiometric equivalent to the polyol component and water is used in the reaction and a successive cure molding process wherein the said practically thermoplastic foamed material is contacted with water or steam to react the isocyanate component remaining therein with water while heating.  The foamed material obtained by the first foaming process is not reached to the final curing of the remaining isocyanate and rigid or semi-rigid at room temperature, but it is softened by heating enable to be used for deep draw molding in the successive cure molding process without crack, split, or demolition.  Then, it is contacted with water or steam in the final cure molding process, to react the isocyanate component remaining therein with water to proceed to final curing, thus becomes a rigid or semi-rigid foamed material without softening by heating.     The intermediate practically thermoplastic foamed material can be laminated with facing materials or reinforced with glass fiber non-woven cloth etc. to give a composite panel with excellent properties such as light weight, stiffness, heat insulation, acoustic insulation and moisture resistance suitable for a molded ceiling or a door panel etc. for automobile use and a partition or a screen for interior use.

Abstract: DOCKET NO. RO986-015 METHOD AND APPARATUS FOR LUBRICATING A MAGNETIC DISK CONTINUOUSLY IN A RECORDING FILE                    Abstract In a magnetic disk file having a plurality of disks and a source of organic lubricant mounted within a housing, an air flow stream recirculates within the housing.  The vapor pressure of the lubricant source is controlled to provide vapor phase transport of lubricant molecules between the source and the disks' recording surfaces.  The lubricant molecules bidirectionally transfer between the air stream and the source, and between the air stream and the surface of the disks, as is needed to maintain a mono-molecular lubricant film, in the range of about 3 to 15 angstroms, on the disks in accordance with the principle of Langmuir kinetics. The disks are rigid disks and their recording surface includes a carbon overcoat.  This overcoat has an affinity for the airborne organic lubricant molecules.      In a first embodiment, the vapor pressure of the lubricant is controlled by mounting the material at the coolest location within the housing.      In a second embodiment, the lubricant is carried as a mono-molecular layer of lubricant on granular carbon particles which have a surface area that is many times greater than the surface area of the disks.            DOCKET NO. RO986-015 In a third embodiment, the vapor pressure is controlled by combining the lubricant with a vapor pressure diluent.

Abstract: SNOW RIDGER          ABSTRACT OF THE INVENTION         A method and an apparatus for producing ridges on snow covered fields are described.  A row of snow is severed from the snow cover and elevated to provide a trench in the snow cover.  The row is then deflected to one side of the trench and deposited on the undisturbed snow covering beside the trench.   This produces a wind barrier on the snow covered field, reducing wind erosion of the snow cover.  In preferred embodiments, two spaced trenches are cut and the rows of snow removed from them are placed on the undisturbed ridge of snow between them.          In the apparatus, the rows of snow are severed, elevated and deposited by a support plate carried on two runners.          The support plate floats on the undisturbed center ridge of snow.   The two rows are deflected to side by side positions for deposit on top of the undisturbed center ridge by a pair of adjustable deflector plates.  The two runners are supported on adjustable skis so that depth control is possible.

Abstract: ABSTRACT            A  new  principle  for  high  efficiency  power conversion at high frequencies is described.  The principle provides zero voltage switching by using  the magnetising current of a transformer or parallel inductance to charge the switch adjunct capacitance and other capacitance during the dead time.  The transformer is prevented from being loaded during the dead time.  An embodiment of the invention is described where loading of the transformer during the dead time is prevented by directing the output inertial current to a capacitor instead of through the rectifiers to the secondary of the transformer.  This can also be achieved by using synchronised rectification that provides pulse width modulated regulation on the output land ensures that the  transformer secondary is separated from the inertial current of the output during the dead time.   Voltage and current stresses on the switching devices and rectifiers are minimised.           The principle may be applied to inverters where the load is resistive.
