Abstract: ABSTRACT OF THE DISCLOSURE:            As overvoltage protection for a series capacitor in a high-voltage network a voltage-dependent resistor,  built up of metal oxide varistors,  is arranged in parallel with the capacitor.  In parallel with the resistor there is a spark gap device consisting of two series-connected spark gaps for shunting the resistor in case of overload thereof.  The energy for triggering the spark gap device is obtained from an auxiliary capacitor,  which is charged during operation, and is supplied to one of the spark gaps via a switching device, controlled by an overload detector,  and a pulse transformer.  A metal oxide varistor is connected in series with the high voltage winding of the transformer.   The transformer is connected so that the triggering pulse is in opposition to the voltage across the series capacitor.

Title: Brushless dc motor control
Inventor: MARKUNAS ALBERT L
IPC: H02P6/06
Filed: 1986-09-05
Granted: 1991-03-26
Abstract: Brushless DC Motor Control Abstract Unlike brush-type DC motors, a brushless perma-nent magnet DC motor has an impedance which is resistive at low rotational speeds and becomes increasingly induc-tive at higher speeds.   Consequently,  a control for a brushless permanent magnet DC motor must control both supply voltage and commutation angle in order to maximize motor performance.  The simultaneous control of both sup-ply voltage and commutation angle is difficult to achieve and requires complex circuitry.   The present invention overcomes this problem by providing first means for de-veloping a motor performance command signal representing a desired motor operational characteristic, second means for developing a motor feedback signal representing an actual motor operational characteristic, and means coupled to the first and second developing means for deriving the commutation angle command signal and the voltage command signal from the motor performance command signal and the motor feedback signal so that the motor operates with the desired operational characteristic.

Granted: 1990-12-04
Abstract: ABSTRACT OF THE DISCLOSURE        A fitting for connecting two structural components.          The fitting includes a locking device mounted on the first struc-tural component and a support device mounted on the second struc-tural component.  A rotary member in the support device defines circumferentially extending conical surface against which the front end of the locking device is pressed when the the two fitting devices are connected.  The force exerted by the front end of the locking device causes the rotary member to be turned.          The rotary member has a helical end face which is initially outside of the range of travel of the locking device.  Upon turning of the rotary member, the helical end face comes into engagement with a countersurface of the locking device.  The resulting connection can only be released by means of a tool.        The structural components are pressed tightly together by a further turning of the rotary member.  A piece of furniture composed of several structural components can be initially connected without the aid of a tool and can subsequently be tightened after the piece of furniture has been assembled.  The fitting makes possible the connection of structural components where the tolerances in assembling the fitting devices are in-accurate or have been exceeded.

Title: Digital power converter input current control circuit
Inventor: HENZE CHRISTOPHER P
IPC: H02M3/158
Filed: 1987-01-28
Granted: 1991-03-12
Abstract: Abstract:     A digital power converter input current control circuit is connected between a power converter and a power source. This circuit monitors, and controls if necessary, the current that flows between the power source and the power converter in a manner that protects the power source, the input current control circuit, and the power converter from the catastrophic effects of excessive current flow. The input current control circuit operates similar to an electronic circuit breaker with an automatic reset feature, in that the power delivered to the power converter is maintained low during fault conditions. Thus, if a power transistor in the power converter should fail, a current limit circuit in the input current control circuit will prevent additional damage to the power converter.  The operation of the input current control circuit, however, is different than that of a circuit breaker in that a control circuit in the current limit circuit allows for current limiting during start-up, transient conditions which prevents the generation of "gliches" or voltage spikes on energized input power lines when the power converter is suddenly activated.

Abstract: ABSTRACT OF THE DISCLOSURE         The present invention relates to coated particulate matter wherein the particles are individually coated with a cured combination of phenolic/furan resin or furan resin to form a precured resin coating on a proppant such as sand, thereby substantially improving the chemical resistance of the proppant over one having a straight phenolic precured coating.       Another embodiment of this invention involves the use of multiple resin coatings on the particulate matter to form a final layered coating containing the desired amount of cured resin.  This multiple coating of particulate material results in a final coated product that has a smoother and more uniform surface than particulate material having its entire resin coating applied in a single operation.

Title: Quick attachable and detachable mower blade assembly
Inventor: OXLEY LONNIE R
IPC: A01D34/00
Filed: 1987-07-13
Granted: 1992-01-28
Abstract: QUICK ATTACHABLE AND DETACHABLE MOWER BLADE ASSEMBLY          Abstract of the Disclosure A quick attachable and detachable mower blade assembly comprising a blade member and blade holder member having flat adjoining surfaces and fixed to the lower end of a vertical drive shaft.  A pair of studs are fixed to and project from one of the members through stud openings in the other of the members.  The latter openings have an enlarged portion for passing the head of the studs and a narrow portion extending from the enlarged portion to an end conforming to the shape and dimension of the shank of the respective stud.  The narrow portions of the openings are located and directed so that the studs, when seated in the respective ends, prevent axial and angular movement between the blade member and the blade holder member.  The blade holder member and blade member have, in addition, a central opening which receives a downwardly biased pin extending from the lower end of the drive shaft.  The pin will automatically sit in this latter opening upon the blade and holder members being positioned so that the studs are seated in the ends of their respective openings.

Title: Kit for making sets of transparent fingerprints using differential adhesion
Inventor: MASON STANLEY I JR
IPC: A61B5/117
Filed: 1987-09-03
Granted: 1991-08-13
Abstract: Abstract A kit for making permanently sealed transparent finger-prints using differential adhesion, including dry ink and means for applying the ink to fingers, a transfer strip having a backing sheet, a transparent adhesive print strip, and a protec-tive cover, a transparent record sheet, print adhesive adhering together the protective cover and the adhesive print strip, back-ing adhesive adhering together backing sheet and the adhesive print strip, and the adhesives having such differential adhesion as to cause  greater adhesion between the adhesive print strip and the the backing sheet than between the adhesive print strip and the protective cover, and greater adhesion between the adhesive print strip and the record sheet than between the adhesive print strip and the backing sheet.
