Abstract: In one embodiment, an apparatus (10) for securing a movable blinds rail (110, 112) to a fixed surface (124) includes a casing (12) having a detent (18) affixed to an inner surface thereof. An elongate rod (20) is included having first (22) and second (26) ends and a protruding member (28) extending from the rod between the ends. The rod first end extends out of a first opening (32) of the casing and the protruding member slidably cooperates with the detent to secure the rod in a first fixed position. In this manner, the apparatus is coupled to the moveable blinds rail, and the rod first end is used to contact a fixed surface to secure the movable blinds rail thereto.

Abstract: A self regulating heater comprises a non-conductive, magnetic core having a coil wound about it and providing pole pieces extending into contact or very near contact with a surrounding ferromagnetic member which in turn may be surrounded by and in intimate contact with a non-magnetic low resistance member; the magnetic member having an effective Curie temperature at the temperature to be maintained.
