Abstract: Apparatus to facilitate putting on and removing footwear. The apparatus may be swivelably coupled to a chair where handles are provided to rotate an arm which is coupled to a footrest. By moving the arm, which is at seat level, the footrest is movable between a stowed position and an operative, forward position.

Abstract: A liquid/gas phase detector system employing a sensor to detect fluid phase, flow rate, and temperature. A flow conditioner in the form of a pipe segment with an inverted V-shaped section forming a weir is adapted for coupling in a horizontal conduit downstream from a source of liquid flow. When a thermal dispersion technology sensor is used, heated and non-heated temperature sensitive elements extend within the pipe segment on the upstream side of the weir. Fluid flow changes encountering the sensing elements cause temperature changes which produce an output signal relating to fluid phase (gas or liquid) and flow rate. Several different embodiments for the flow conditioner are provided.
