Abstract: Provided is a wallboard repair clip which includes a patch wallboard receiving structure for contacting inner and outer surfaces of a patch wallboard, an existing wallboard receiving member and a locking structure. The locking structure and existing wallboard receiving structure are constructed such that inner and outer surfaces of the existing wallboard are contacted once the patch wallboard is in a repaired position within the existing wallboard.

Abstract: Provided is a method of providing warm air to the intake of a engine of a vehicle to improve fuel economy and reduce emissions of said vehicle. The method includes the steps of:transferring warm air directly exiting a radiator to an air intake of an engine using a variable vane which flexes and rebounds to continuously adjust an amount of warm air being supplied to said air intake in response to various engine loads;allowing said variable vane to flex and rotate an air deflection surface of said variable vane to a position which supplies an increased volume of warm air to said air intake as a warm air load against said air deflection surface is increased; andallowing said variable vane to rebound and rotate said air deflection surface to a position which supplies a decreased volume of warm air to said air intake as a warm air load against the air deflection surface of said variable vane is decreased. The invention also provides an apparatus for practicing the method.
