Abstract: A carrier for holding a circuit board while passing round an automated insertion line has a rectangular frame with support members extending in from the inner periphery. In a particular example, the support members on three sides have support surfaces and lateral locating surfaces. Spring retaining members are provided, one above each support surface. On the fourth side, support members only have support surfaces in the example. At each end of the fourth side, a laterally deflectable cantilever spring member holds down the circuit board along the fourth side. An external flange provides a support for the carrier on a conveyor. The inner periphery is shaped to avoid interference with the solder wave and to avoid causing turbulence.

Abstract: A fish lure has a bouyant casing containing a pump and a battery mounted inside a watertight compartment providing positive bouyancy to the casing. A spray nozzle is mounted on top of the casing and is driven by the pump. The prepulsive force of its discharge causes rotation of the casing about a vertical axis. The underside of the casing is open and leads into a water chamber which fills with water quickly when the lure is placed in the water, to provide it with a self-righting capability. The outside of the immersed portion of the casing is of frusto-conical shape and has horizontally-spaced upright reflectors attached to it. As the casing rotates, the reflectors produce an occulting effect under water which appears to attract deep-swimming fish to it. A light may also be provided on the casing for night fishing.

Abstract: A decoy anchoring mechanism with a detachable reel and weighted handle is mounted vertically under the keel of a decoy using a pivoting cam and clamp assembly.
