The pedal frame comprises a pair of spaced legs onto each of which is telescoped an elongate extruded tread member or block having formed therein open-ended passageway or channel means receptive of a frame leg and a reflector element, the frame legs each having a pair of spaced parallel rigid flanges outwardly turned to overlie and underlie the reflective element, thereby to buffer and protect the reflective element against twisting and compressive forces directed onto the tread member by the fo...

A platen having a wall defining a reflective supporting surface upon which a first sheet of material is to be supported for exposure of graphic intelligence on the first sheet by directing light toward the platen and first sheet to afford reproduction of said graphic intelligence on a second sheet. The wall may be formed with a multiplicity of orifices communicating between the first sheet on the supporting surface and a means for reducing air pressure in the orifices to attract the first sheet ...

Projection of an image from a transparent photographic element onto a screen without deterioration or destruction of the transparent photographic element, by projecting a beam of light through a transparent photographic element bearing reflective image areas.

A soft fill luminaire for minimizing shadows on the field to be illuminated is provided with reflective barndoors. The barndoors raise the level of fill illumination at the center of the field without materially reducing the fill illumination at the margins of the field.

A reflective film includes a substantially non-drawn film having a layer A that includes a resin composition A containing a resin having a refractive index of less than 1.52 and titanium oxide. The titanium oxide has a refractive index of 2.5 or more, and a vanadium content of 5 ppm or less, and the film has a light reflectance of 95% or more to light having a wavelength of 550 nm, and a heat shrinkage ratio after treatment at 80.degree. C. for 180 minutes of greater than -0.1% and less than 1.0...

A light transmissive film having a smooth surface and a structured surface. The structured surface has a series of triangular prisms running parallel or concentric to one another. A reflector is placed adjacent to the smooth surface so that light entering the film at an angle which is close to parallel to the smooth surface will emerge from the film at a predetermined angle with respect to the incoming beam. A light fixture utilizing the film is also disclosed.

The invention provides for a linear reflective device having a plurality of concave reflective regions disposed along a reference line, such that normal incident light is focussed to a focal region by all of the reflective regions. The reflective device may be curved in a direction normal to the reference line or be planar. The invention further provides a method and means for manufacturing the reflective device by rolling, pressing, or molding. The invention still further provides optical, radi...

A sign for displaying reflective numerals which are slidably engaged in slots provided by a backing plate. The sign is adapted for display in any one of three modes, namely, a bottom portion of the backing plate is coupled with a base stand for upright positioning; or alternatively, the top portion of the plate is coupled to a hook assembly to allow for a hanging arrangement; or lastly, the backing plate may be simply attached to a flat surface.

A reflective marker for highway striping, signs and other surfaces is produced from a multiplicity of thermoplastic or thermosetting granules in the shape of tetrahedrons. A plurality of glass spheres having a diameter in the range of from about 6.0 microns to about 0.125 inches are substantially evenly dispersed throughout each granule with some of the spheres protruding through the outer granule surfaces. To form the granules the glass spheres, the granule material and a suitable pigment are m...
