  • Patent number: 5109460
    Abstract: An optical fiber array is disclosed that is useful in a print head of a thermal printer. The array is comprised of materials that hold a collection of output ends of optical fibers in precise alignment to each other and to a well defined plane. The materials of the array are selected so that each material has a polishing rate that is substantially the same. This selection of materials facilitates efficient fabrication of the arrays. Additionally, a fixture that facilitates ease of assembly and finishing of the array is disclosed.

  • Patent number: 5078089
    Abstract: A spray coating booth for enclosing individual articles to be coated with a liquid spray while the articles are supported in closely spaced relation on an article conveyor for movement through the booth includes a rigid frame with fixed sidewalls and movable top and end walls which may be moved between a closed position completely enclosing an article supported on the conveyor and an open position to permit articles to be moved into and out of the booth. The movable top assures against coating liquid dripping onto and contaminating articles moving on the conveyor which are not to be coated. The end walls are supported for movement in substantially a transverse vertical plane to permit close spacing of articles on the conveyor without contact of the articles by the end walls.

  • Patent number: 5037028
    Abstract: A multi-functioning water-directing device is described comprising an input garden hose coupler, a series of straight pipe sections, an U-shaped transition pipe section, a straight output water-directing jetting segment, and a handle all coupled together by a plurality of coupling means. As a result, fluid flow can be directed both downstream and upstream relative to said handle and eventually exit from the jetting segment in a desired output pattern. In accordance with one aspect, the handle (positioned in parallel contact with at least the U-shaped transition section and the jetting segment and in series contact with at least the input hose coupler), is constructed so that its interior is placed in fluid contact with passing fluid stream wherein the weight of the contained fluid adds handling stability as the device is dynamically moved through a series of working positions such as relative to an overhead rain gutter and high riding motor vehicle.

  • Patent number: 4985250
    Abstract: The invention provides a water/oil/water duplex emulsion in which the external continuous phase is gelled. This gelling is obtained by having an osmotic pressure component, e.g. an electrolyte, in the internal aqueous phase which draws water from the external phase through the oil phase. The structure is firm but contains a considerable volume of available aqueous phase. The structure is of value in e.g. foods and cosmetics.

  • Patent number: 4977494
    Abstract: A system bus (13) carrying multidimensional path data interfaces with a plurality of local microprocessors (24), one for each dimension, through a plurality of dual access memory structures (21), one for each local microprocessor (24). A local arbiter (35) controls access to each dual access memory structure (21), facilitating elimination of wait states in data transfers between the bus (13) and memory (21) and between the local microprocessor (24) and memory (21). The arbiter (35) is implemented using a programmable logic device state machine approach, which implements a mode of operation wherein the circuitry is armed for a transfer between a local microprocessor (24) and the dual access memory (21) and accomplishes such transfer with no wait states.

  • Patent number: 4912753
    Abstract: A digital robotic axis controller which employs a digital processor to apply the inverse of a plant model transfer function to positional information representative of a target path to generate a feed forward position control signal and to combine an error signal with the positional information to generate a feedback control signal. The feed forward and feedback control signals are combined to produce a total position control signal which is supplied to a digital-to-analog converter and then to a plant comprising an amplifier, a motor for establishing the actual position of a robotic member, and an encoder for deriving the error signal from the motor position. In application, a number of such plants are controlled to achieve a coordinated multidimensional movement with increased accuracy.

  • Patent number: 4893068
    Abstract: A digital servo system for causing a mechanical element (48) to track a desired path and hold various positions along the path and employing a lead/lag integrator (18) in parallel with a feedback control loop. The input to the integrator (18) is switched between velocity (V.sub.EK) error during pathtracking and position error (E.sub.K) during holding to increase the resistance of the mechanical element (48) to position changes caused by outside forces during both pathtracking and holding. The integrator function employed uses a term (U.sub.integrator(k-1)) representing a previous integrator output value to assist in smoothing perturbations caused by switching between position and velocity error.

  • Patent number: 4849270
    Abstract: Weatherstripping is produced continuously by two or more spaced apart tufting heads, which may be operating at different stitch rates. The or each strip of weatherstripping comprises at least two rows of tufts sequentially inserted by two tufting heads. Heated dies may be located between the tufting heads for transforming rows of tufts inserted by the first tufting head at least partially into film to form barrier fins. The knuckles of the tufts are flattened, a secondary backing applied, and then individual strips of weatherstripping separated by ultrasonically slitting, all as a continuous process enabling weatherstripping of various constructions to be efficiently and economically produced by tufting.

  • Patent number: 4817743
    Abstract: Formation of a double sandwich braze joint between the steel body of a bit and a carbide insert tip disposed in a groove formed across the body is facilitated by a butterfly-type shim having a semiopened bottom placed within the groove between surfaces on the bit body defining the groove and adjacent surfaces on the insert tip. The shim has a pair of upstanding spaced side walls and a pair of spaced bottom webs extending between and interconnecting the side walls so as to dispose them between adjacent side surfaces of the bit body groove and insert tip, with lower edges of the shim side walls disposed generally above the bottom webs. The bottom webs rest on the bottom surface of the bit body groove and, in turn, elevate the shim side walls so that their lower edges are spaced above the groove bottom surface.
