Abstract: A method of supporting loose fill insulation in a wall cavity with a flexible cloth. The cloth is secured to the wall cavity frame by initially fastening the upper and lower edges of the cloth to the upper and lower plates, and then permanently gluing the cloth to the vertical studs with a flowable adhesive. A small punch hole is made in the cloth to accommodate an installation tube, which is preferably angled at its end to facilitate reaching into small spaces and cracks. Loose fill insulation is blown into the cavity behind the cloth after inserting the installation tube through the punch hole in the cloth. The quality of the adhesion of the cloth to the studs can be assessed by observing the color of the studs through the cloth.

Abstract: An apparatus for monitoring and warning of an undesirable velocity condition in a rotating shaft includes a magnetic reed switch having on and off domains oriented with respect to an actuation magnet which is displaced on an outward radial path with respect to the shaft by centrifugal force, such that the actuation magnet can pass from within an on domain to within an off domain and vice versa, thereby switching the reed switch on and off according to the speed of rotation of the shaft. The reed switch is connected electrically to a warning light or buzzer or control circuit. An alternative embodiment employs a ferromagnetic shield variously interposed between the actuation magnet and the reed switch in response to centrifugal force.
