Abstract: A wildfowl decoy has an improved anchor storage system including a cavity within the body of the waterfowl decoy for receiving and storing an anchor. Vertical walls and a recessed area within the cavity prevent horizontal dislodgment of the anchor. A retaining mechanism engages the anchor to prevent vertical movement of the anchor thus preventing an accidental removal. The anchor may be easily removed when intentional removal is desired.
Abstract: The disclosure relates to a moving target assembly for use in a target practice range. The moving target assembly includes a target, a target travel guide for guiding the target movement and including a pair of straight sections which are substantially at right angles to one another, and a chain drive running substantially parallel to the straight sections. The target includes selectively operable chain engaging devices so that the target may be selectively guided along one straight section or the other. The assembly also includes structure for returning the target to a home position. Also disclosed is a control for controlling a plurality of such assemblies, including selection of the targets, the speed of target travel, the raising and lowering of the targets, and the actuation of the chain drive motors.
Abstract: A miniaturized cardiotachometer is worn by a user typically adjacent the volar aspect of the wrist or the temple to provide the user with a numerical readout of his or her pulse rate. The time between two heartbeats is measured by the number of pulses from a fixed frequency source that occur. The measurement is made after a predetermined delay to eliminate or reduce noise signals, the number of pulses of the fixed frequency being converted into the pulse rate and displayed numerically.

Abstract: The disclosure relates to a target assembly of the type for use in a target practice range. The target assembly includes a base, a motor in the base, a first rotatable member coupled to the motor, a second rotatable member and a pivotable target member coupled to the second rotatable member. The first rotatable member includes an extension which engages a radial slot within the second member during rotation to cause the second rotatable member to rotate for raising and lowering the target member. The first and second rotatable members have cooperating cam surfaces for locking the target member in a vertical and horizontal position and for freeing the rotatable members for rotation during the raising and lowering of the target member.
Abstract: The disclosure relates to a forward-reverse film transport synchronizing mechanism for a motion picture projector film feed apparatus of the type including a shuttle which is driven for vertical reciprocating motion by a transport cam. The mechanism of the present invention includes a rotary shutter which is driven by a rotating shaft and includes a pair of drive lugs arcuately spaced by 180.degree. and axially spaced from one another. A transport cam drive means coupled to the transport cam and including a driven lug which is selectably engageable with one or the other drive lugs causes the transport cam to rotate when the rotating shaft rotates. Because the driven lug is selectably engageable with either of the drive lugs, the angular relation of the transport cam relative to the rotary shutter may be varied by 180.degree. thus providing properly synchronized forward and reverse film transportation without requiring reversal of the angular direction of rotation of the rotating shaft.
Abstract: The disclosure relates to a selectively operable power supply for a recording system of the type which includes tuning and intermediate frequency sections for receiving and converting transmitted television signals into composite video and audio signals and a recorder for recording the composite video and audio television signals onto a recording medium. The power supply comprises a timer including a switch which is selectively operable for providing an A.C. line voltage when its contacts are closed at preselected times and a receptacle coupled to the switch and adapted to receive the power input of the recorder for powering the recorder at the preselected times and a rectifier and filter coupled to the switch for powering the tuning and intermediate frequency sections with filtered DC voltage at the preselected times.
