A display panel comprises a substrate having disposed thereon a plurality of display elements, each display element comprising a pixel electrode disposed on the substrate; a scan electrode disposed on the substrate separate from the pixel electrode; two display drive elements, one disposed over a first part of the pixel electrode and the other disposed over a first part of the scan electrode; an insulating layer extending over at least a second part of the pixel electrode and the two display dri...

An assembly for use in a door panel or the like comprises a pair of spaced substantially parallel rigid longitudinal channels which include tracks for receiving a substantially planar sheet of cover material and crossmembers are arranged to contact the inner face of the sheet material, the channels and braces being attached to the inner face by an adhesive. The longitudinal channel and crossmembers may be adjustable to provide a variable dimension assembly. The crossmembers include an elongated ...

An arrangement for modifying impressed radars signals with an internally generated signal to establish a misrepresentative return signal which is confusing as to actual range, size and position.

The invention relates to a unique panel joint specifically adapted for quickly assembling or disassembling panels to the configuration of a container, a building structure, or the like. Specifically, a unique flexible hinge arrangement is provided for vertical joints, while a quick-fitting locking arrangement is provided at all base horizontal joints. The base joint comprises a flange on the vertical member mating with a recessed beveled groove on the base member, and a plurality of screws threa...

A light panel which may be used from either side to produce two different lighting effects. The panel is a translucent sheet having a plurality of protuberances on one side and a plurality of indentations on the opposite side. Each of the protuberances has a plurality of plane surfaces intersecting the plane of the sheet, and each of the indentations has a plurality of plane surfaces also intersecting the plane of the sheet.

Disclosed herein is a cast or molded structural panel having two plates or sheets integrally joined to an intermediate zone. The intermediate zone is formed either of a cross corrugated panel or a double tray structure between the plates. The cross corrugated panel may be regarded as having a first set of corrugations perpendicularly intersecting a second set of corrugations. The double tray structure may be described as two arrays of hollow pyramids whose bases are joined to one of the sheets. ...

A laminated panel for use in the construction of vehicles bodies or buildings comprises a pair of substantially rigid outer layers (1,2), separated by a core (3) of foamed plastics material. The core includes a plurality of spaced elongate inserts (4) of hard plastics material such as ABS. The inserts act as anchor points for attachment of lashing rails or the like externally of one of said outer layers (1,2).

A panel switch according to the present invention has a switching unit comprising a plurality of switches which are not provided with individual click means and at least one click mechanism for the switching unit. Because the switching unit does not incorporate individual click mechanisms, the panel switch can be formed into a small size. In addition, by the integration of the provided click mechanism, the degree of freedom on the design of the panel switch is enlarged, and a small-sized panel s...

A continuous process for making a core for a composite panel comprising cutting spaced apart tongues in columns from a metallic sheet, the tongues being foldable about base lines in the columns each base line being separated from the next tongue in the column by a web; folding the sheet to form a castellated structure having continuous side walls constituted by the spaces between adjacent columns of tongues with the webs of adjoining rows respectively lying in spaced apart parallel planes and op...

A panel formed as a laminate with a decorative fabric at the exposed face includes a pair of foamed resin layers as backing material. Between the foamed resin layers is a fiber glass layer for strength. Means are provided to attach the panel to a substrate.
