Primary reflector for solar energy collection systems [PDF]

open access: yes, 1978
A fixed, linear, ground-based primary reflector is disclosed which has an extended curved sawtooth-contoured surface covered with a metalized polymeric reflecting material. The device reflects solar energy to a movably supported collector that is kept at

Optimization of Watt's Six-bar Linkage to Generate Straight and Parallel Leg Motion

open access: yesInternational Journal of Advanced Robotic Systems, 2008
This paper considers optimal synthesis of a special type of four-bar linkages. Combination of this optimal four-bar linkage with on of it's cognates and elimination of two redundant cognates will result in a Watt's six-bar mechanism, which generates ...
