A device for determining the angle of incidence (alpha) of incident radiation and particularly sunlight (S) includes an array of light sensitive elements (10, 11 and 12) and a shadow mask (15) arranged above the elements. The shadow mask (15) includes a transparent region (14) and a non-transparent region (13) with a linear boundary or edge (16) therebetween. The linear edge (16) is arranged above the center of the linear array (9) of light sensitive elements (10, 11 and 12) so as to extend at a right angle relative to the linear direction of the array. To determine the angle of incidence (alpha), a coarse determination of the number of completely shaded light sensitive elements (10), and a fine determination of the fractional shading portion of the partially shaded light sensitive element (11) immediately adjacent to the completely shaded elements, are carried out. In this manner, a very high precision and accuracy can be achieved, exceeding the physical resolution determined by the size of the individual light sensitive elements, while still maintaining a simple and reliable construction. The angles of incidence (alpha) and (beta) in two perpendicular planes can be determined by providing a two-dimensional array of light sensitive elements in connection with a shadow mask having a two-dimensional checkerboard pattern of transparent regions and non-transparent regions.

A device for squeezing various household collapsible tubes comprises two lever handles, two pintles, two torsional springs, a primary roller, and a secondary roller. The lever handles are held together by and are free to rotate about the two pintles, forming a double non-crossing class 1 lever arrangement. The rollers, held in gudgeons by snap fit, are also free to rotate. The primary roller is distinguished from the secondary roller by having a crank at one end. The torsional springs, anchored by the pintles, provide a torque which causes the two rollers to clamp together. Operation of the tube squeezing device proceeds by inserting the crimped end of a collapsible tube between the rollers and turning the crank, thereby turning the rollers so as to squeeze the tube flat and to push its contents toward the nozzle end. Insertion and extraction of the tube is effected most readily by applying a compressive force to the two lever handles, creating a gap between the rollers for the tube to easily pass through.
