Title (EN) RADIATION CONCENTRATING SYSTEM
(FR) SYSTEME DE CONCENTRATION DE RADIATIONS
Abstract:
(EN) A high efficiency radiation concentrating system for reflecting incident rays from a displaceable source (S) to a fixedly positioned focus (F) utilizing a simple universal displacement mechanism (22). The universal displacement mechanism (22) is coupled to a minor element (16) such that the minor element (16) is rotatably actuated about a first axis line (24) and a second axis line (28) in response to movement of an actuating arm (50) and is provided with a positioning mechanism (38) for maintaining the plane of the minor element (16) normal to a bisecting line (32) of an incident and a reflected angle of radiation impinging on and being reflected from the minor plane. The displacement mechanism (22) drives the mirror element (16) about the first axis line (24) extending in a direction from the displacement mechanism (22) to the focus (F) and further drives the minor element (16) about a second axis normal to the rust axis line (24). In this manner, the minor element (16) is maintained in a predetermined positional relation for reflection of the incident radiation to the fixed focus (F).
(FR) Systeme de concentration de radiations a haute efficacite reflechissant des rayons incidents provenant d"une source mobile (S) et convergeant vers un foyer (F) fixe, utilisant un joint universel (22). Le joint universel (22) est accouple a un element reflechissant (16) de facon telle que l"element (16) soit anime d"un mouvement de rotation autour d"un axe (24) et d"un second axe (28) sous l"action du mouvement d"un bras d"entrainement (50) et comporte un mecanisme de positionnement (38) permettant de maintenir le plan de l"element reflechissant (16) perpendiculaire a la bissectrice (22) de l"angle forme par les directions d"incidence et de reflexion de la radiation frappant le miroir et reflechie par celui-ci. Le joint universel (22) entraine l"element reflechissant (16) en rotation autour du premier axe (24) dirige du joint universel (22) vers le foyer (F) et entraine egalement l"element reflechissant (16) autour d"un second axe perpendiculaire au premier axe (24). Ainsi, l"element reflechissant (16) est maintenu dans une position relative predeterminee permettant de reflechir la radiation incidente vers le foyer fixe (F).
