Abstract: An electric light has a casing with a depth that is less than half as great as its width. This is rendered possible by the use of a compact, precision reflector which permits a focused, parallel-directed beam despite the configuration of the casing.

Abstract: A reflector for an electric light has a first reflector member with a socket for the light bulb and a second reflector member positioned generally forward of the socket. In one aspect of the invention a first angular segment of the first reflector defines curved reflector means for reflecting light from the light in the socket into a collimated beam. The remaining angular segment of the first reflector defines a transversely directed, curved reflector for focusing light from the light bulb back to the filament in the light bulb to increase the filament temperature. In another aspect of the invention, the first, angular segment of the second reflector member defines a transparent partition, with the partition carrying a plurality of transparent ridges of triangular cross section. The ridges are circumferentially disposed at different radii about an extension of the central axis of the socket. Thus light from the light bulb in the socket is diffracted by the ridges into the collimated beam.

Abstract: A multilayer label comprises a front sheet having an adhesive-coated side. A multilayer folded leaflet member adheres to a portion of the adhesive coated side in a position spaced from the ends of the front sheet. A first line of tearing weakness is defined on the front sheet, with the folded leaflet defining a short-folded front layer adhering to the adhesive-coated side. Thus an edge of the front layer lies spaced from parallel edges of the folded leaflet, and some of the adhesive-coated side adheres to the folded layer of the leaflet member adjacent the front layer. Tearing of the first line of weakness exposes the leaflet member, a portion of which may preferably be removable by tearing a second line of weakness formed in the leaflet member.
