DEFINITION

Classification: 126/579

Fluid expansion sensor:

(under subclass 573) Apparatus wherein the sensing means includes a device which detects change in volume of a liquid or gas. [figure] [caption]A solar collector includes a plurality of elongated parallel reflectors mounted for rotation about their respective longitudinal axes, together with mechanism coupled to the reflectors for simultaneously

rotating the same. An elongated absorber is arranged parallel to the reflectors for collecting solar radiation focussed thereon by the reflectors. Tracking means including two solar sensor reservoirs containing a vaporizable/condensible liquid working medium is provided for rotation of the reflectors to control the focussing of solar radiation on the absorber.
