Abstract: This relates to an identification system for authenticating labels and cards. Each label or card would be provided with authenticating characters which are printed in color and which are at least in part in overlapping relation so as to make it difficult to identify the individual characters by eye. However, when a pair of overlapping characters is viewed through a colored filter, depending upon the color of the filter, one or other of the two superimposed characters would appear. By providing the authenticating characters in a preselected arrangement and utilizing colored filter segments in a similar preselected arrangement, only those authenticating characters which form part of the authenticating information would appear.

Abstract: A tamperproof package for containers of ingestible material such as aspirin, nonprescription drugs, food products and the like, comprising a thin layer of an elastomeric material stretched thinly over the outside surface of a container or other article such that the material will rupture and split upon being punctured. The outer edges of a sheet or opening in the elastomeric material are gathered together tightly around the container and closed by tying a string around the gathered material and/or by gluing or solvent welding. Excess material is trimmed from the gathered end. Dry lubricant is provided between the container and the elastomeric layer to facilitate movement of the elastomeric material over the surface of the container in the event of rupture of the elastomeric material. A pattern or content label can be printed onto the outside of the elastomeric layer subsequent to packaging.

Abstract: A labeling mechanism (10) for sequentially dispensing labels (49) from a backing strip (51) onto articles includes a pair of pinch bars (74) each having a knife edge (76) which bears against the rear edges of the labels (49) and downwardly against the backing strip (51) to move the labels along a pressure plate (66). The pinch bars (74) move in a linear reciprocating manner so as to push the labels (49) and backing strip (51) toward a labeling head (104) which also moves in a reciprocating manner and transfers the labels (49) from the backing strip (51) by means of air suction as the labels are stripped from the backing strip (51) by a knife edge (70). When the articles to be labeled are sensed as being in proper position, a positive air stream is pneumatically directed through the labeling head (104), thereby blowing the labels (49) onto the articles.

Abstract: A light fixture incorporating a motorized insect exterminator includes a frame, a light source, and a motor mounted on the frame. A drive shaft of the motor is connected to an end of a clear and pliable plastic impeller. A translucent plate is mounted between the light source and plastic impeller. The free end of the impeller is rotated between 2,000 and 3,600 RPM's by the motor, sweeping out a circular area in the proximity of the plate on the opposite side from the light source. Flying insects, attracted to the light source, fly toward the light source, slow down to land on the plate, fly through the circular area at a relatively slow speed, and are fatally hit by the rapidly revolving impeller. The impeller is flexible enough and light enough to not injure or cut a finger which comes in contact with the rotating impeller.
