Abstract: Abstract of the Disclosure A light detector consisting of a thin film of metallic (or conducting) material having an induced anisotropy in conjunction with means for establishing a temperature gradient in the film in a direction normal to the plane of the film is disclosed.  When thin films of molybdenum and tungsten are excited by a pulsed laser light at normal incidence to the film, transverse thermoelectric voltages are generated. Output voltages across a 50 ohm load of 10 millivolts have been observed for an incident laser pulse of approximately 1 KW.  Wave lengths in the range of 0.46-1.06µm and pulse widths of approximately 3 to 300 nanoseconds produce output voltages.  A correlation between intrinsic film stress and output voltage indicates that stress (one of induced anisotropy) in the metal film introduced during deposition or externally induced anisotropy such as can be produced by a magnetic field in magnetic materials gives rise to a nonscalar absolute thermoelectric power even though the metal films are usually considered to be isotropic in their transport properties. The output from the detector, in terms of polarity, may be reversed by reversing the direction of light incidence. Also, the direction and magnitude of the output may be con-trolled by adjusting the position of the metallic film relative to a pair of contacts disposed in sliding relation-ship with the metallic film. While not necessary to the practice of the present invention, an electrically insulating substrate is preferably used to cause a better temperature gradient normal to the plane of the film.  In general, the response time of the films is dependent on the laser pulse width.

Abstract: ABSTRACT OF THE DISCLOSURE                 An omnidirectional optical scanner scans bar coded labels  passed relative to a rectangular scan window with a plurality of interlaced X's whereby the labels are completely scanned irrespective of their orientation.  The interlaces X's are generated from a laser light source directed onto a first oscillating mirror for deflecting the light beam in a horizontal direction at a slow frequency.  A second oscillating mirror is positioned to further deflect the light beam in a vertical direction at a higher frequency.  The horizontal and vertical frequencies are set at a particular ratio so that the X's overlap and the scan on the return passes midway between the legs of a previous scan.  The horizontal and vertical amplitudes are controlled by horizontal and vertical photo detectors located adjacent the scan window which provide inputs to amplitude control circuits to assure an orthogonal pattern by keeping the crossing angle constant.  The oscillating mirrors are phase and frequency locked by a precision digital system to assure phase lock stability and thereby prevent voids in the scan pattern.  The scan window crops out the end portions of the scan pattern.  Generally, the most linear parts of the scan pattern, but including the turn around portions of the scans within the scan window are used.  However. in one embodiment, end mirrors fold the end portions of the scan pattern outside of the window into the scan window toward the center thereof to enhance the scanning of certain labels.

Abstract: CONVENIENCE CLOSURE WITH SAFE EDGES          ABSTRACT OF THE DISCLOSURE  A convenience closure having a removable central panel.          A convenience closure is attached to a can end to seal the can.  The closure includes a removable central panel; a panel fold with an endless severing line formed in its upper surface; a chuck wall fold which has a nose  portion that extends radially inwardly farther than the severing line and overlies the severing line; and a pull tab, attached to the central panel, which has a nose portion that extends to the severing line.  The panel fold includes a nose portion that extends to a position adjacent to and under the severing line.  To remove the central panel, the pull tab nose is depressed to break the severing line.  Then, the pull tab  is moved upwardly to complete the breaking of the severing line and remove the central panel.  Breaking the severing line forms two sharp raw edges; one lies under the nose of the chuck wall fold and is thus protected.  The other raw edge is formed adjacent the nose of the panel wall fold.  This edge is burnished and roller into the panel wall fold nose by interference with the nose of the chuck wall fold during removal of the central panel.
