US Patent:

41084012, Aug 22, 1978

Filed:

Dec 7, 1976

Appl. No.:

5/748339

Inventors:

Matthew A. Sullivan - Elkins Park PA

Assignee:

Sullivan Products, Inc. - Willow Grove PA

International Classification:

B64D 2700
F16M 1300

US Classification:

244 54

Abstract:

A motor mount for use in model airplanes is disclosed. The motor mount includes a mounting plate and a pair of spaced arms extending generally perpendicularly from the mounting plate. Each arm includes a generally horizontal surface for supporting flanges of a motor or engine and an angled surface spaced above and sloping toward the horizontal surface. A clamping plate is secured to each of the angled surfaces. Each clamping plate secures a flange of the motor to one of said horizontal surfaces. The clamping plates can be secured to one of a plurality of locations along the longitudinal dimension of each arm.

International Classification:

H02K 500

US Classification:

310 89

Abstract:

A housing is provided for hand-held starter motors, such as those commonly in use for starting model airplanes by imparting a torque to the spinner or nose cone of the airplane. The housing is provided with a guard to protect the hand holding the motor during the starting operation, as well as means for resting the motor on a horizontal surface without rolling. The housing comprises a cylindrical casing and an end plate through which the shaft of the starter motor extends. The end plate has a flange which extends beyond the circumference of the casing for a distance sufficient to prevent the fingers of the hand from sliding past the end plate while holding the motor. Extending from the flange of the end plate generally parallel to and overlying a portion of the outer surface of the casing is a curved protrusion having a surface which approximately fits the curve of the hand between the thumb and forefinger when the hand is holding the motor. A flat edge on one portion of the flange allows the motor to be rested on a horizontal surface without rolling. Preferably, the housing is provided with a strip switch for operating the motor, and a projection from the casing may serve as both a mounting member for the strip switch and a third point for resting the motor on a surface.

Abstract:

A method and system for controlling peak electrical demand placed on a source of electrical energy by a plurality of electrical loads that include at least one electrical load of lower priority than at least another of the loads. Demand for electrical energy by the loads connected to the source of electrical energy is sensed and, in response to the sensed demand exceeding a predetermined value the loads are selectively disconnected from the source. Normally, all the loads are connected to the source in the absence of a sensed excessive demand condition. Therefore, all demand control is lost in the event of failure of the controller. Accordingly, the system senses an abnormal operating condition of the controlling system of the type that renders the selective disconnecting means inoperative to disconnect the loads from the source. The electrical load of lower priority is then disconnected from the source for the duration of the sensed abnormal condition. Also disclosed are a system and method for selectively disconnecting loads from a source on the basis of either demand and time or merely demand.
