  • Patent number: 5198281
    Abstract: A non-woven towpreg fabric and a method of production therefor. The non-woven towpreg fabric is fabricated from a plurality of flexible, multiply towpregs, comprising towpreg plies which comprise reinforcing filaments substantially wetout by a matrix forming material, which then are bonded together to form the fabric. The method of production for the non-woven towpreg fabric involves spreading the reinforcing filaments, coating the reinforcing filaments with the matrix forming material in a manner causing interfacial adhesion, forming the towpreg plies by heating the matrix forming material until the matrix forming material liquefies and coats the reinforcing filaments, cooling the towpreg plies in a manner while said towpregs remain substantially unconsolidated until the matrix forming material solidifies, overlapping a plurality of the towpreg plies, and bonding the towpreg plies together. Multidimensional fabrics, preforms and composite articles also can be formed by this invention.

  • Patent number: 5195744
    Abstract: A baseball batting practice apparatus includes a display screen having a passage therethrough and a video projector for projecting a moving image of a baseball pitcher on the screen adjacent the passageway. An electronic control unit detects that the baseball pitcher of the moving image is about to release a pitch in the moving image and creates a signal. In response to the signal, a baseball retaining and releasing mechanism adjacent a conduit is controlled for allowing a baseball to be released and to travel, urged by gravity, along the conduit toward a baseball pitching machine which is positioned to one side of the display screen. The electronic control unit is adapted to synchronize the propelling of the baseball through the passageway with the moving image such that the propelled baseball appears to be thrown by the moving image of the baseball pitcher. The electronic control unit is associated with and controlled by a personal computer.

  • Patent number: 5191216
    Abstract: A solid state, quantum mechanical electron/hole wave device in the form of a switch or multiplexor includes a layer of semiconductor material supporting substantially ballistic electron/hole transport and a periodic grating structure formed in the layer of semiconductor material, with the grating structure comprising a modulation in electron/hole potential energy and/or effective mass. Preferably, means are provided for applying and varying the grating modulation. By constructing the device to divide the input substantially completely into two output beams (to operate in the Bragg regime), a useful switch is provided. Likewise, by constructing the device to divide the input into a selected number of three or more output beams (to operate in the Raman-Nath regime), a useful multiplexor is provided.

  • Patent number: 5184974
    Abstract: A method and device for transverse dividing of a slaughtered bird, in which the carcass of the bird hanging by the legs in a conveyor is moved along with the breast in the direction of conveyance, the method comprising the steps of: placing the bird in an oblique position relative to the conveyance direction in such a way that the legs are in front of the rest of the carcass, viewed in the conveyance direction; bringing down the chest relative to the legs by exerting an essentially downward directed force on both sides thereof, so that the plane in which the transverse dividing operation takes place lies below the thighs and above the chest; and dividing the bird into a back half hanging from the conveyor and a front half. Prior to the dividing operation, the skin is cut through along the top edge of the thighs adjoining the chest.

  • Patent number: 5178890
    Abstract: A method for removing, killing or bringing into a passive condition of bacteria on and in the skin of slaughtered, plucked poultry by a chemical, mechanical and/or temperature treatment is disclosed, wherein the treatment(s) are effected after plucking of the poultry and prior to the opening of the carcass thereof. The skin of the poultry is preferably subjected to an acid treatment with an acid solution and a heat treatment at a temperature of about 50.degree. C. for two to three minutes. The poultry can be immersed in or sprayed with water at the desired temperature, the water being mixed with an acid. Advantageously, the skin of the poultry is brushed with rotating brushing elements, at the same time spraying a spraying liquid on the poultry from above and from the sides.

  • Patent number: 5176563
    Abstract: A method and device for separating the legs from a carcass of slaughtered poultry in which the carcass is positioned on the rear side, legs pointing upwards, relative to the cutters, a groin incision is made between each leg and the carcass at the side of the leg facing the carcass, and each leg is dislocated at the hip joint by pressing out each leg relative to the carcass. After dislocating the hip, a caudal hip incision is made in the remaining tissue connection between each leg and the carcass, after the two parts of each dislocated hip joint are moved a certain distance apart by applying a force acting on the hip joint ball of each hip joint, pushing the hip joint ball away from the hip joint socket prior to making the hip incision, and the legs are pulled off the carcass, essentially in the lengthwise direction of the back bone and away from the tail part.

  • Patent number: 5176513
    Abstract: A pulse combustor apparatus for burning solid fuel comprises a Rijke-type combustor tube and has a rotating fuel bed for defining a primary combustion zone adjacent the fuel bed. The rotating fuel bed tends to minimize agglomeration of solid fuel and accumulation of ash during combustion by agitating the solid fuel. An inlet conduit is provided for introducing a low nitrogen gaseous fuel to the combustion air upstream of the combustion zone to minimize the formation of NO.sub.x in the primary combustion zone. In other embodiments, inlets are provided downstream of the primary combustion zone for introducing additional air or gaseous, low nitrogen fuel for air staging or reburning to minimize the emission of NO.sub.x. Sorbents, such as limestone, are introduced above the bed to minimize SO.sub.2 emissions.

  • Patent number: 5175433
    Abstract: A monodisperse aerosol generator forms a stable jet of liquid at a velocity allowing columnar breakup into droplets of uniform size and spacing. To prevent degradation of the monodisperse aerosol, it is disposed by entrainment in a high velocity gaseous stream. To provide an interface for direct injection onto a particle collection device or into an infrared or Raman spectrometer or to interface a liquid chromatograph with a particle collection device or an infrared or Raman spectrometer, the generator is followed by a desolvation chamber operation at about atmospheric pressure and a multistage pressure reducer which evacuates solvent vapor and gaseous medium to form a high momentum, solvent-depleted solute aerosol beam which is input into the infrared or Raman spectrometer.

  • Patent number: 5173077
    Abstract: A method and device for performing an accurate cutting operation near the knee joint of a leg of a slaughtered animal, in particular a bird, the device comprising mechanical means, such as conveying elements and guides, for handling the leg, and cutting means, such as rotary or stationary knives for performing the cutting operation, e.g. for making an incision prior to scraping off meat of a bone or for cutting through the leg. With the device, the desired cutting accuracy is obtained by using mechanical positioning means which operate on the kneecap of the leg, which is preferably bended in the knee joint in its natural bending direction by bending means. The positioning means may comprise one or more supporting elements with a stop edge, which can be moved along the thigh of the leg to against the kneecap.
