Abstract: A tool for extracting a broken flight support shaft from inside a threaded barrel of a dart assembly, has an extraction bit contained within an associated handle. The handle defines a dart barrel assembly receiving bore for guiding the dart barrel into contact with the extraction bit and associated extraction securing points.

Abstract: A water proof member protects casts, splints, or other appliances or surgical dressings from water damage. A combination of a securing member and straps secure the member and provide a water proof seal between the water proof member and the wearer.

Abstract: A temperature controller with an integral liquid level control contained within one unit. The unit consists of an electrical and heat conductive housing, which serves as a first electrode of the liquid level sensor. A metal clamp and a means to attach the housing to the liquid vessel is insulated from the housing and serves as a second electrode. The electrodes are connected in an electrical circuit such that when the electrodes are immersed within a conductive liquid the resistance between the electrodes is reduced and a current is allowed to flow. A temperature sensor, such as, a thermistor, RTD, or thermocouple, is contained within the housing. The housing conducts heat from the housing environment for radiation within the housing.

Abstract: A catching device for attachment to the rear of a truck or truck bed preferably for a dump truck arrangement, has a sheet member having attachment and fastening portions which, when suitably applied to the rear of the truck bed, generally prevents debris, rocks, stones, pebbles and the like from falling off a rear lip, shelf, or other truck bed structure upon which debris may accumulate, or for collecting debris that slips through the gap between the tail gate and onto the road or pour plate.

Abstract: A ladder platform preferably for extension ladders, has supports for receiving ladder rungs and supporting the platform in a generally level condition on any desired position between the top and the bottom of the ladder. The ladder platform provides support for someone working on the ladder and items that might be needed while working on the ladder.
