  • Scrambling and descrambling of video signals using horizontal line combinations
    Patent number: 5617475
    Abstract: A plurality of video lines in a raster scan video image are scrambled by delaying a first video line in time equal to the horizontal line scan time for the raster scan video field to produce a delayed first video line. The delayed first video line is inverted to produce an inverted delayed first video line and one of the delayed first video line, the inverted delayed first video line and a null signal is added to a second horizontal video line to produce a horizontal line of a scrambled video signal. The scrambled horizontal lines of video information are descrambled by delaying a first scrambled horizontal video line in time equal to the horizontal line scan time for the raster scan video field to produce a delayed first scrambled video line.

  • Method for obtaining a lithographic plate
    Patent number: 5616445
    Abstract: A method for making a lithographic printing plate according to the silver salt diffusion transfer process image-wise exposes an imaging element with a high intensity short time scanning exposure. The imaging element comprises on a support in the order given a silver halide emulsion layer and a layer containing physical development nuclei. A thus obtained image-wise exposed imaging element is subsequently developed in the presence of a developing agent and silver halide solvent. The image-wise exposure is focused substantially within the silver halide emulsion layer of the imaging element. The present invention further provides an apparatus for carrying out the above method.

  • Combination hydraulic pressure regulator and pressure switch
    Patent number: 5613516
    Abstract: A combination hydraulic pressure regulator and pressure switch includes a housing having an interior chamber connecting an inlet port to an outlet port. A seating device is movably received in the interior chamber and has a seat surrounding an opening. The opening is in communication with the outlet port. A poppet is movable in the interior chamber. An adjustment spring normally urges the poppet into engagement with the seat to close the opening, the poppet being movable in a direction away from the seat in response to hydraulic pressure in the interior chamber sufficient to overcome the force of the adjustment spring. A limit switch is mounted to the body. A switch actuator is associated with the poppet for actuating the limit switch in response to movement of the poppet in a direction away from the seat.

  • Handling partly completed containers
    Patent number: 5613828
    Abstract: Successive flat skillets (S) are picked from a stack (12) and fed to a conveyor (2) by a mechanism which has devices gripping adjacent side faces to a fold line of a skillet to open the skillets to their tubular form during the transfer movement. The gripping devices (22,24) pivot on an axis coincident with the skillet fold line to allow the skillet to be opened to its full tubular form without distortion. The mechanism is so arranged that the skillet reservoir stack (12) can be oriented in a plane substantially parallel to the conveyor path for the opened skillets, in order to minimize space requirements.

  • Support for a self-propelled linear motion drive apparatus
    Patent number: 5609107
    Abstract: The invention supports a mechanical carriage at three contact points for precise positioning on two guide rails, one guide rail having a V-grooved surface and the other having a flat surface. Two of the three contact points are recirculating ball bearings mounted against the V-grooved rail. The third contact point is on the flat rail and is also the driving contact point and comprises a drive shaft having a friction wheel thereon engaged with the flat rail to drive the mechanical carriage. The recirculating ball bearings and friction wheel are loaded against the V-grooved and flat rails, respectively, by magnets mounted on the carriage and spaced from the rails by an air gap. The air gap provides for a magnetic force between the magnets and the guide rails while permitting relative movement therebetween.

  • Implant connector
    Patent number: 5607304
    Abstract: A threaded connection for medical implants utilizes root and crest interfnce profile, such that the major and minor diameters of the thread profile on the male and female members of the connection are selected such that the minor diameter of one member is larger than the major diameter of the other, such that an interference condition is created along the helical path of the thread. This interference condition increases the radial stability of the connection and increases the torque required to loosen the connection when made up.
