Abstract: A frequency stable oscillating device includes an oscillating transistor. A heating element is disposed in close proximity to the oscillating transistor. A temperature sensor is mounted in close proximity to the oscillating transistor. A temperature control device supplies a variable signal which is dependant upon a local temperature of the oscillating transistor, wherein the variable signal controls the operation of the heating element. The heating element may alternately consist of one or more resistive patches, or one or more heating transistors which are biased to provide sufficient heating. The oscillating device may be formed from either IC or MMIC technologies, and may be formed from either silicon or GaAs.

Abstract: Disclosed is a device for drawing an archery bowstring and for automatically releasing it when the draw weight of the bowstring exceeds a predetermined valve. This is a main body having a front end that anchors the terminal ends of a forwardly extending flexible cord loop, and having a rear end adapted to have attached an archer's hand loop. A lever mechanism is pivotally mounted to the body and has an initial position in which a lever edge portion is angled so as to releasably retain the bight of the loop after the loop has been engaged around the bowstring. A spring-biased member, with a screw to adjust spring force, is also mounted in the body, and provides a depressible projection which will engage one side of a cam-like protuberance carried by the lever mechanism to hold it in its initial position.
