  • Patent number: 5201919
    Abstract: A gas scrubbing device having inlet and outlet ports that allows a gas stream to enter the scrubber from the bottom and exit through the top. The gas direction is reversed several times, fed through a venturi to accelerate the gas flow, and passed over two sumps containing scrubbing liquid. The combination of the high speed gas flow, gas flow reversal, and scrubbing liquid removes most particulates from the gas. The gas flows upward through a mist of scrubbing liquid created by a spray nozzle, and as the gas flows beyond the mist it flows through a series of deflection vanes which spin the gas to remove liquid droplets. The gas then passes through a series of serpentine vanes which cause the gas to change direction flow removing additional liquid droplets from the gas, through a reducing element, and out through the outlet port.

  • Patent number: 5198877
    Abstract: This method and apparatus optically samples numerous points on the surface of an object to remotely sense its shape utilizing two stages. The first stage employs a moveable non-contact scanner, which in normal operation sweeps a narrow beam of light across the object, illuminating a single point of the object at any given instant in time. The location of that point relative to the scanner is sensed by multiple linear photodetector arrays behind lenses in the scanner. These sense the location by measuring the relative angular parallax of the point. The second stage employs multiple fixed but widely separated photoelectronic sensors, similar to those in the scanner, to detect the locations of several light sources affixed to the scanner, thereby defining the absolute spatial positions and orientations of the scanner. Individual light sources are distinguished by time-multiplexing their on-off states.

  • Patent number: 5164982
    Abstract: Existing voice telephone communications are augmented in a simple and understandable way by the addition of a "dumb" display terminal at a subscriber's location. Text, graphics, and picture data can be transmitted in ASCII code or other protocol, over existing, standard telephone lines and displayed on the terminal. The "dumb" feature is due to the display terminal having a voice/data selector that can automatically recognize digital data and switch from voice communication to data communication modes. Accordingly, this display terminal is entirely self contained and is controlled from a remote location, such as a telemarketing agents position, requiring nothing more from the subscriber than mere possession of the display terminal.

  • Patent number: 5157670
    Abstract: Disclosed is a disk controller having an interruptable error correction code circuit for accumulating a remainder during the writing to or reading from data storage media in a disk storage device. An ECC clock latches each bit of data into the circuit when data is being transferred. The ECC clock is controlled by an ECC clock control circuit that monitors sector data and redundancy data transfers to interrupt the ECC clock when sector data transfer is suspended before redundancy data transfer is started. The ECC clock is then allowed to resume after the suspension is complete. Sector data transfer is suspended while the read/write head of the data storage device is passing a defect in the media of the storage device. Since the ECC clock control circuit interrupts the ECC clock while data transfer is suspended, the remainder accumulation will be interrupted while the defect is being passed. While the remainder accumulation is interrupted, the circuit acts as if data is not being transferred during this time.

  • Patent number: 5154363
    Abstract: A self-contained reciprocating action miller having a grinding mill housed within a mill housing and rotating about a grinding axis. A refuse hopper mounted above the mill housing has a convex floor with an opening therein to expose the grinding mill. Reciprocating feed apparatus mounted within the refuse hopper reciprocates two parallel, spaced-apart vertical walls along an axis parallel to the grinding axis to gradually feed the refuse into the grinding mill at a steady rate to prevent jamming of the mill when grinding tough refuse. Shear plates in the form of segments of a circle are positioned adjacent the rotor for comminuting shreddable or grindable material while guiding noncomminutable materials through the mill. A reversible rotor, stator, and discharge chute allow the comminuted material to be discharged from either side of the mill with no loss of grinding efficiency.

  • Patent number: 5155820
    Abstract: A set of processors and instruction set for a pipelined multiprocessing architecture with separate code and data streams is disclosed. The overall architecture considered interlocks instruction execution with the destination transfer of results and includes automated input and output of array data. The data is dispensed from a central memory that is associated with the control unit and all results and inputs are automatically returned to this central memory over a second bus. Once the processors receive their data they operate independently and several instructions may be in the process of being executed at the same time with destination validity checking being used to coordinate the activity. The central memory may contain partitions, called circular partitions, or first-in/first-out buffers which make it possible for it to automatically prefetch or output array data. The instructions include overlapping address and operand length bits.

  • Patent number: 5144513
    Abstract: A multifunction threading apparatus for threading a tape, such as a magnetic tape, from a tape cartridge along a tape path is disclosed. This multifunction threading apparatus includes a single cam connected by a guide arm to a threader arm which is capable of engaging and withdrawing the tape from the tape cartridge. Rotation of the cam causes rotation of the threader arm, which in turn withdraws the tape and threads it along the tape path and in contact with cleaning stations comprised of a two-sided vacuum assisted fabric wiping station and a vacuum assisted scraping station eventually delivering the tape to a take-up wheel. This tape path also includes air bearings with ceramic capped springs. A displacement arm slideably connected to the cam allows for temporary displacement of one side of the fabric wiping station to facilitate threading.

  • Patent number: 5115305
    Abstract: An improved polarized color video projector incorporates a light source to provide three collimated beams of linearly polarized light of blue, green, and red colors. A light modulator capable of imparting a video image in a light beam is positioned in each of the three colored beams to modulate the individual colored image components in each of the beams. A dischroic beam recombiner receives the modulated blue and green beams, and recombines them into a combined blue and green color image carrying beam. A polarization-selective/beam analyzer/recombiner receives the recombined blue and green beam and recombines it with the red beam. A retarder placed between the light modulator for the red beam and the polarization-selective/beam analyzer/recombiner, in the path of the modulated red beam, rotates the plane of polarization of the red beam to allow it to be recombined with the recombined blue and green beam in the polarization-selective/beam analyzer/recombiner.

  • Patent number: 5083816
    Abstract: Disclosed is a human and machine readable label which is divided into three areas. The top portion of the label, which is typically half the length of the label, is divided into two columns. One of these columns contains a bar code with a quiet zone at each end of the bar code. This bar code contains the entire message of the label in a machine readable bar code format. The other column of the top portion of the label contains the first few characters of the human readable portion of the message. The bottom portion of the label contains the remainder of the human readable message and is printed throughout the entire width of the label, thus allowing the characters to be a much larger size that the human readable characters contained in the top portion of the label. The label is of a size that allows it to be placed on one end of a 3480 style tape cartridge, as well as allowing it to be placed on other types of media such a file folders.

  • Patent number: 5084656
    Abstract: Disclosed is a system having a vertical position register and a horizontal deflection controller to position an electron beam within a CRT used to project an image onto a photographic medium for printing. When data is being displayed on the CRT, the beam is positioned vertically to the desired color phosphor row and then swept across the face of the CRT while the data is used to modulate the beam. During retrace, the beam is stopped at the center of the CRT and displaced vertically to a home position while waiting for the next dot row of information. The home position is located above the center of the phosphor area so that no leakage occurs if the beam remains in the home position for extended periods. Furthermore, while in the home position at the center of the CRT, the horizontal deflection amplifier dissipates a minimum amount of power.
