Abstract: A water supply control apparatus for use in homes or other structures is provided that incorporates a battery-operated radio frequency wall switch transmitter and an electrical plug-in receiver regulating the open or closed state of an electrical solenoid valve in fluid communication with a structure's water supply. A by-pass switch enabling manual regulation of the solenoid valve is mounted on the valve itself. Also provided is a method of controlling the flow of water supplied to a structure utilizing radio frequency pulse broadcasts to regulate the open or closed state of the solenoid valve.

Abstract: A hanger for supporting decorative electric wiring from a building structure, comprising an elongated base member having a spatulate like projecting blade containing top and bottom surfaces which are serrated, a strap attached to and depending from the bottom surface of the base member, and a clamp carried by the depending strap and having springable jaws for securely holding at least one electrical conductor.

Abstract: A hanger for a Christmas tree ornament, comprising, a stem having two ends with an eyelet at one of the ends thereof, a pair of divergent springable jaws having free ends symmetrically disposed about the extended center of the stem and being attached at a central hinge point which hinge point is integral with the opposing end of the stem, and enlarged end portions carried by each of the free ends of the springable jaws.

Abstract: Our invention relates to an improved anti-curl feature for constant-force springs to be used in lifting a stack of shells by means of a follower in a multiple cartridge magazine for firearms thereby lessening the transverse curl in at least the uncoiled portion thereof that is responsible for causing its side margins to dig into the wall of the shell casing or bullet or both and cause jamming, such improvement comprising the localized weakening of spring along a longitudinally-extending line spaced between its side margins such that it lies flatter, preferably by providing same with a single column of longitudinally-spaced apertures or two or more such columns thereof in which adjacent pairs thereof are transversely misaligned. Our invention also encompasses the method of eliminating the aforementioned jamming problem by locally weakening the spring longitudinally such that at least its uncoiled portion lies flatter.

Abstract: This invention relates to a curved or angled multiple-round rifle cartridge magazine of the type designed for use with ammunition having tapered shell casings necked-down at their small end to accommodate a relatively smaller bullet characterized by a pair of negator springs attached for pivotal movement in spaced substantially parallel relation one behind the other to a sidewall of the shell chamber and a follower having front and rear side-opening spring-coil-receiving pockets for the coiled portions of the springs that permit the coils seated therein to tilt as the follower moves up through the chamber and the uncoiled portions of the springs change their angular relation to the latter and to the shell stack, both of the springs having medial portions lying between their coiled ends and the points of attachment to the magazine sidewall that curl inwardly toward the shell stack with the front spring of the pair being so located relative to the stack that its leading edge lies forwardly of the annular should

Abstract: The invention relates to an improvement in a multiple-shell weapon magazine or clip of the type employing either one or a pair of transversely-curved negator springs fastened to a particular sidewall of the cartridge chamber alongside the stack to lift the shells one-at-a-time through the open top thereof on a follower which is characterized by the spring or springs being so arranged and sized that the rearmost incurled edge of one seats within the annular grooves encircling the rear ends of the shells in the stack while the foremost incurled edge of the same or another spring curls around the bullets thereby alleviating any undue pressure applied to the shell casings by the medial portion of one spring or the adjacent edges of the pair that otherwise could cause the stack to jam. The invention also encompasses the method of preventing the shells from jamming in such a magazine by sizing and positioning the spring edges in the manner aforementioned.
