Abstract: Reflector dish having a reflective surface for reflecting incident radiation to a focal region and a receiver for receiving radiation reflected by the reflective surface. A reflective surface support (26) supports the reflective surface. A receiver support (2) supports the receiver substantially in the focal region of the reflecting surface. The receiver support (2) includes at least one first elongate member (4) extending from substantially the central axis of the dish towards the outside of the dish, and a second elongate member (6) extending from the outer end of the or each first elongate support member (4) and connected to the receiver for supporting the receiver. The receiver support (2) is not in load bearing contact with the reflective surface (26). The reflective surface support (26) and the receiver support (2) are each supported by a support means (34) provided generally on or close to the central axis of the dish.

Abstract: An exercise machine for exercising the arms and legs with a seat height adjustable to a lower and a upper position, in the lower position a preacher rest is also provided which places the elbow joint of the user when sitting on the seat in line with a pivot. Members are attached to the pivot which the user rotates to exercise his arms. The seat in the upper position places the knee joint of the user, when seated on the seat with the preacher rest removed, in line with the pivot members are then rotated about the pivot by the user bending his legs about the knee. Resistance to the exercise is provided rotation of the pivot.
