Abstract: AUTOMATIC HIGH-SPEED WRAPPING MACHINE       ABSTRACT An automatic high-speed wrapping machine for wrapping packages in heat sealable thermoplastic film is disclosed wherein the film seal at the side and ends of the packages is made at a high rate of speed as the packages travel through the machine.          The packages travel continuously in a straight line through the machine and are delivered at the input end of the machine by a flighted infeed conveyor into a film inverting head where the packages are surrounded by the film, thence to the side sealing mechanism which forms a seal while severing the selvage from the packages, then into an end sealing mechanism where both ends of the packages are sealed and the film web connecting succeeding packages is severed.  The machine produces packages which have a sealed film wrap around the entire package which is then in con-dition for subsequent shrinking of the film if desired to pro-vide a package having a tight film overwrap.

Abstract: ABSTRACT OF THE DISCLOSURE              A  laser recording system is disclosed in which a beam of light from a laser is split into first and second beams.   The first beam is modulated with digital signals from a computer and deflected by a rotating mirror onto the surface of a photoconductive drum.  The second beam is deflected by the rotating mirror onto a curved timing plate.  The surface of the timing plate is provided with a series of unevenly spaced re-flective markings representative of evenly spaced spot positions on the surface of the drum.  Light reflected by the timing plate as the second beam scans its surface and strikes the reflective markings impinges on a photodetector located at the center of curvature of the timing plate and is converted by the photo-detector into a corresponding series of electrical signals.      The electrical signals are converted into pulses which are used to gate the flow of digital signals from the computer so that the light spots formed on the drum by the first beam are evenly spaced and not effected in their placement by the changing angular velocity of the first beam as it is swept across the drum.

Abstract: DECODER HAVING A TRUE AND A COMPLEMENT OUTPUT        Abstract A digital decoder for use with a dual bus system is provided having a minimum number of transistors.  The decoder is easily expandable to decode larger binary coded input signals.  As a minimum only six transistors are needed to decode a three-bit binary input signal to provide outputs for a data bus and its complement.  By using a minimum number of transistors, less current is required for the decoder.  The circuitry used to provide each decoded output is repeated in a manner which conserves silicon area when the decoder is placed on silicon.  A minimum number of control lines are used.

Granted: 1984-05-15
Abstract: ABSTRACT              Hologram apparatus for detecting flaws has a photo-graphic station for supporting a photosensitive medium.  The photographic station together with the photosensitive medium forms a developing chamber with a transparent face having a depth in the range of from about .005" to about .125, preferably from about .005" to about .080".  The developing chamber has a periphery with a contour which always changes at an angle greater than about 115° and is preferably circular.  Associated hydraulic equipment supplies and removes fluid from the developing chamber.  A laser supplies coherent light for the article to be tested for reflection to the photographic station.  A reference beam is directed to the photographic station.  For use in inspecting pipe in the field, the apparatus advantageously has a housing and a pair of saddles each having different diameter pipe re-ceiving portions and a strap securing system.  The photographic station can develop the photosensitive medium in situ and may be used in any spatial orientation.  The invention also comprises the photographic station per se without the laser.
