Abstract: A toy airplane operable by air pressure through a blowpipe is designed to make effective use of the full air pressure supplied to the blowpipe to enhance its flight distance and speed. The airplane includes a tubular support member having a plugged front end and an open rear end into which the blowpipe is insertable. A cover member is mounted on the tubular support member and shaped to form an aircraft body with wing and tail elements. The tubular support member includes an annular accordion fold section spaced rearwardly from its front end to provide airtight sealing engagement with the blowpipe and to exert a gripping force on the blowpipe which must be overcome by the air pressure to launch the toy airplane into flight.

Abstract: A device for recirculating warm, moist air from a clothes dryer exhaust into a room is attached to the standard vent pipe of the dryer. The device comprises a length of corrugated, sheet aluminum tubing having a substantially right-angled bend. One end of the tubing is placed on the dryer vent pipe. The opposite end of the tubing beyond the bend extends parallel to the side of the dryer and slips into a double ply, nylon mesh, filter bag. The bag is releasably secured to the end of the tubing with a resilient band which seats within an annular recess formed at the end of the tubing. The tubing has an approximately elliptical profile beyond the right-angled bend so that the dryer can be located close to an upstanding wall for best floor space utilization. The nylon mesh prevents sticking by lint and other materials exhausted by the dryer for easy emptying.
