Abstract: A solar light collecting device includes: a rectangular-shaped frame-like body 22 supported by a strut body 21 so as to be tiltable in a vertical plane; a flexible reflecting mirror 24 having two side edges 22a held by the frame-like body 22 and a quasi-parabolic cross section along the short sides thereof to reflect solar light; and a tilting cylinder device 25 which tilts the frame-like body 22 according to the altitude of the sun and guides the light reflected by the reflecting mirror 24 to a heat collecting device disposed at the focal point of the reflecting surface of the reflecting mirror. A curve adjusting device 27 contacts the rear surface of the reflecting mirror 24 according to the tilting position of the reflecting mirror 24 to change the degree of curve of the reflecting surface.

Abstract: A low thermal mass heat reflector for use with a fireplace grate which has a combustion zone directly thereabove when fuel is burned thereon in a fireplace. The heat reflector comprises a first portion for absorbing radiant energy from the combustion zone and reradiating thermal energy back into the combustion zone, and a second portion for absorbing radiant energy from the combustion zone and reradiating thermal energy over the fireplace grate and out of the fireplace.

Abstract: A reflector screen for a fireplace consisting of a rectangular central screen of reflective material hingedly interconnected with first and second side panels of reflective material for placement in the rear of a fireplace in surround of the fire.

Abstract: An apparatus for enhancing the visual effects of a fire and for increasing its heat utilization comprising intermediate brackets having rear parts and front parts for removably supporting a mirror in an orientation offset from the vertical within a fireplace behind the fire, the rear parts including outwardly projecting fingers near an upper end and a lower end and a mirror coupled to the front part and formed of a reflective surface selected from the class of temperature resistance reflectors including glass mirrors and polished stainless steel; upper brackets having rear parts and front parts removably supporting a mirror in an orientation offset from the vertical within a fireplace behind the fire, the rear parts including outwardly projecting fingers near an upper end and a lower end and a mirror coupled to the front part and formed of a reflective surface selected from the class of temperature resistance reflectors including glass mirrors and polished stainless steel; and lower reflective components havi

Abstract: A screen, e.g. fire-guard is provided for heating a room by convection using the heat from a radiation heat source, e.g. an open hearth fire, a gas-fire or an electric radiant heater, and when the heat source is an open hearth fire for use as a fire-guard preventing sparks or other small particles of combustion from entering the room in which the fire is located. The screen includes a row of at least with their upper portions spaced apart vertical pipes having each at or near their lower end an inlet opening and at or near their upper end an outlet opening for air sucked from the room by the chimney-action of the warm pipes. The pipes of at least one pair of adjacent pipes of the screen are hingedly interconnected for the rotation of one of these pipes about the longitudinal axis of the other pipe thereof by coupling and clamping means.
