  • Patent number: 5308484
    Abstract: A filtration apparatus for thermoplastic synthetic plastics material comprises a housing (1) in which a carrier body (4) formed by a piston, for two screen nests (8,9) is bearingly supported for displacement in direction of its axis. In the filtration position the melt streams from a supply channel (2) via inflow channels (10 to 13) into distribution spaces (14,15) located in front of the screen nests (8,9), then through the screens and via outflow channels (18,19) into a discharge channel (3). Each distribution space (14,15) is subdivided by at least one wall (21) and into each of the so formed compartments terminates an inflow channel (10 to 13).

  • Patent number: 5306298
    Abstract: An adjustable laryngoplasty device is provided for medializing a paralyzed vocal cord in a larynx. The device includes an anchoring plate, a prosthesis member, and a pair of adjustment screws which are threaded through the anchoring plate and rotatably connected to the prosthesis member. A window is formed in the patient's thyroid cartilage adjacent the paralyzed vocal cord and the prosthesis member is extended through the window so that it presses against the underlying vocal cord. The anchoring plate is secured to the outer surface of the thyroid cartilage with self-tapping screws which are extended through apertures in the anchoring plate and imbedded into the thyroid cartilage. The adjustment screws are rotatable for moving the prosthesis member relative to the anchoring plate and thereby adjusting the medial position of the vocal cord in the larynx.

  • Patent number: 5302029
    Abstract: A flexible storage container for the transportation of liquid foods, such as orange juice, includes an outer tear resistant shell having a linear closure in a front or end face thereof, and a replaceable inner liner which is inserted into the outer shell through the closure. The outer shell further includes a vent through which air can escape from the space between the inner liner and outer shell. The inner liner includes a filler fitting which is fed through the outer shell. The container is characterized in that it is elongated in shape and has a front or end face that bulges to conform to filling pressure. The front or end face is reinforced by a flexible bar that extend essentially perpendicular to the base. The container is further characterized in that the closure, and fittings for filling, emptying and venting are located in the front or end face.

  • Patent number: 5300010
    Abstract: A mechanical apparatus and method for producing a folded paper rose from an elongated strip of paper. The apparatus is operated by feeding an elongated paper strip through a rotating shuttle assembly, and securing the end of the paper strip onto a slotted stem which is rotated simultaneously with the shuttle assembly. Rotating the shuttle assembly causes a pair of shuttles to cooperate with a paper folding member adjacent the ends of the shuttles to produce a series of sequential folds in the paper strip. Meanwhile, the stem is simultaneously rotating to assemble the folded paper around the stem. Once the paper is fully assembled around the stem the folded paper strip is compressed toward the top of the stem to form a compact flower assembly at the end of the stem.

  • Patent number: 5295950
    Abstract: A pressure dressing for use in the treatment of an auricular hematoma or other ear injury is formed from a thin strip of ductile metal having first and second spaced end portions which are joined by a central connector portion. A pair of foam sponge pads are adhesively affixed to an inner surface of the first and second end portions. In use, the connector portion is reversely bendable to position the pressure pads in closely spaced, substantially adjacent relation on opposing sides of the ear. The pads engage with opposing sides of the ear and exert pressure thereon so that blood does not reaccumulate in the injured area. The dressing may further include one or more tongue or arm portions which extend outwardly from the end portions and are bendable over and around the cartilaginous rim portions of the ear to maintain the dressing in position during periods of physical activity.

  • Patent number: 5296834
    Abstract: A bimetallic disc assembly for a bimetallic disc-actuated thermostatic switch includes a disc retainer, a bimetallic disc received in assembled position on the disc retainer and a metallic retainer cap for retaining the disc in assembled position on the disc retainer and for securing the assembly to the body portion of the thermostatic switch. The disc retainer is adapted to minimize heat flow from the metallic cap to the disc retainer by minimizing the areas of contact between the disc retainer and the cap. The disc retainer is integrally formed from a ceramic material and it includes a central hub having an axial bore extending therethrough, a circular flange extending radially outwardly from the hub, a circular shoulder extending upwardly from the flange, and a peripheral rim extending upwardly from the shoulder. The peripheral rim includes a horizontal edge with a plurality of circumferentially spaced projections or bumps which extend upwardly therefrom.

  • Patent number: 5284341
    Abstract: A football is provided with rearwardly extending fins which promote a tight spiralling rotation of the football when it is thrown through the air. A first of the fins is joined to the football by a centrally located notch therein which interlocks with a second fin integral with the football body when the first fin is passed through a centrally located slot in the second fin and adjacent football body. The fins include flat end surfaces which may be received on a supporting surface for supporting the ball in an upright position. The rearwardly extending fins elevate the body portion above the supporting surface and thereby make it easier to kick.

  • Patent number: 5283754
    Abstract: The invention relates to a procedure for measuring angles and angular characteristics, i.e. the interdependence between the angular deformations or displacements of structural parts and the acting forces or torques by means of a gyro. In the procedure the measurements can be carried out by means of a single gyro and result in a high measurement accuracy. It requires a repetitious execution of a multitude of measurements and in addition to the registration of measurement data and measurement times, the registration of reference data which are in definite connection with the angles to be measured (R-data). From the differences of the gyro measurement data and the measurement times for equal R-data the gyro measurement errors are computed and compensated accordingly.

  • Patent number: 5278538
    Abstract: A bicycle security system includes a locking bicycle rack and employs a user's automated teller banking card to operate the system and debit charges accrued in connection with use of the system from the user's bank account. The locking system has an electronic control means which locks and unlocks the bicycle rack by means of a banking card. The electronic control means includes a timer which tracks time in connection with use of the system. The control means thereafter calculates a charge based upon the use of the system and debits the accrued charges from the user's bank account via telephone modem. The locking bicycle rack incorporates three locking pins which lock the bicycle at the frame, the front wheel and the rear wheel to provide a high degree of security.
