Abstract: A right angle clamp is usable for mounting a condition sensor to an apparatus, such as a valve and the like. The clamp includes a bracket having first and second sides. The first side has a pair of elongated slots therein for receipt of a pair of straight-bolts. The bolts pass through the yoke of an associated valve, between the yoke uprights and the valve stem, and are secured to a substantially U-shaped, elongated retaining member having an open end. Each bolt is secured to the retaining member by threaded nut. A substantially U-shaped reinforcing member is positioned between the retaining member and the nut to prevent distortion of the retaining member when the retaining member is in tension. The elongated retaining member allows for easy installation and adjustment of the clamp.

Abstract: An ionization smoke detector is disclosed in which an electric field is established in an ionization chamber which includes an outer cup-shaped electrode defining the chamber and having side wall apertures for permitting airflow therethrough and a circular inner electrode within the chamber. A radiation source is arranged to produce bipolar and unipolar regions in the chamber. A cylindrical control screen coaxial with the outer electrode and spaced therefrom is electrically connected to and supported by the inner electrode in the chamber.
