Abstract: A personal electrical injury protection system is provided which can be worn by electricians, construction workers, or other individuals working around or with low-voltage lines (i.e. generally less than about 600 volts). The personal electrical injury protection system has both a proximity warning component which provides a warning of potential electrical hazards upon close approach to the low-voltage power line and an electrical contact protection component which turns off the power upon actual electrical contact with the power line. The present personal electrical protection system relies on a radio frequency transmitter attached to the worker or person to be protected and a radio receiver/controller connected to the power line. The radio frequency transmitter has a low frequency generator which is used for electrical-contact protection and a high frequency generator which is used for proximity warning.

Abstract: An animated bird decoy including a body and a pivoting mechanism mounted therein is disclosed. The pivoting mechanism pivots the body relative to a support assembly inserted into the earth. The pivoting mechanism includes a battery-operated motor, which creates a rotary motion, which rotary motion is transformed into reciprocal motion and which is in turn transformed into pivotal or oscillatory motion of the body in a vertical plane about a pivot axis of the support assembly. The support assembly is pivotal in a horizontal plane to selectively present a high profile to game birds. A method of the invention shows how a bird decoy body can be modified to include the pivoting mechanism.

Abstract: A bird decoy including a body and a flapping mechanism mounted therein is disclosed. The flapping mechanism moves a pair of wings, which oscillate with respect to the body. The flapping mechanism includes a battery-operated motor, which creats a rotary motion, which rotary motion is transformed into reciprocal motion and which is in turn transformed into pivotal or oscillatory motion about a pair of pivot points. A method of the invention shows how a bird decoy body can be modified to include the flapping mechanism.

Abstract: An air flow control valve for directing air flow within a house or building. The control valve can selectively direct air flow between two alternative air flow paths. The control valve is of generally cylindrical configuration having an open wall portion or an open wall portion and an open base. The cylinder valve is pivotally mounted within a chamber providing air flow communication through ductwork with at least one thermal source area and at least one area of thermal need.

Abstract: A modular solar heat controller contains four chambers through which heated air is deflected to an area of need, such as a house or building. One of the chambers contains a conventional air blower while the remaining three chambers are connected by ductwork to the building as well as a solar heat collector and solar storage unit respectively. Each of the four chambers, which are arranged in quadrants, is open to the next adjacent two chambers, making a total of three passageways through each chamber, except the chamber containing the blower, which does not connect to the outside and therefore has only two passageways. Two of the three passageway type chambers have control cylinders adapted to selectively close one of two predetermined passageways within the chamber permitting flow through the chamber by the other two passageways. In this manner the controller acts in three separate modes. In the first mode it can funnel air from the collector through the blower to the building.

Abstract: Dielectric fluids having good electrical properties, low viscosities, low vapor pressures, low freezing points, high flash points and excellent biodegradability comprise a mixture of an alkylhalodiphenyl oxide and a chloro- or bromodiphenyl oxide.

Abstract: Heat transfer agents containing at least about 20 volume percent of diphenyl oxide and at least 20 volume percent of diphenylyl phenyl ether, polyphenyl ether or mixtures thereof have been found to be excellent heat transfer fluids with an unexpectedly broad range of liquidity.

Abstract: The well-known heat transfer fluid consisting essentially of the eutectic mixture of diphenyl oxide and biphenyl is improved by the addition thereto of monomethyl- or monoethylbiphenyl. The resulting fluids have very nearly the same boiling point and heat stability as the binary eutectic but have substantially lower freezing points.
