  • Patent number: 9607638
    Abstract: A recording head includes a layer of plasmonic metal deposited on a surface of the recording head. One or more non-self-supporting layers of crystalline material are attached to the plasmonic metal, the one or more layers of crystalline materials configured to form an active region of a laser. A waveguide is configured to receive plasmons from the laser and direct the plasmons to a recording medium.

  • Patent number: 9576595
    Abstract: A mounting surface of a read/write head is prepared to receive an epitaxial layer. The mounting surface is proximate a waveguide of the read/write head, and the waveguide is configured to receive an optical output from the epitaxial layer. The epitaxial layer is transfer printed on to the mounting surface. The mounting surface maintains a vertical alignment between the optical output and the waveguide. The epitaxial layer is processed to form a laser integrated with the read/write head.

  • Patent number: 9558770
    Abstract: A dual-slot waveguide receives energy from a coupling waveguide. The dual-slot waveguide includes first and second light propagating regions of low-index material located side-by-side in a direction normal to a light propagation direction. Inner sides of the first and second light propagating regions are separated by a first region of a high-index material. Second and third regions of the high-index material surround outer sides of the first and second light propagating regions. A near-field transducer receives portions of the energy from the first and second light propagating regions.

  • Patent number: 7347772
    Abstract: A conveyor system for linked sausage strands having a frame with an operating platform. The platform has opposite first and second ends, opposite sides, a top surface, and a wall extending along the sides and ends. A channel is formed in the top surface and a conveyor chain is disposed within the channel. Secured to the chain are a plurality of pivotable hooks that are movable between a loading position and an unloading position.

  • Patent number: 7182684
    Abstract: A method of stuffing natural casings with emulsion involves placing a follower against an upstream end of the natural casing to slide the natural casing forwardly along a hollow meat stuffing tube. The follower is mounted on the stuffing tube and advances the natural casing towards a discharge end of the stuffing tube, where sausage emulsion is injected into the natural casing. The follower pushes the filled casing through a hollow conical-shaped restricting device adjacent the discharge end which limits the outer diameter of the filled natural casing to ensure the uniform shape of the casing as it enters the twisting mechanism. The follower is connected to a longitudinally movable shaft that is parallel to the stuffing tube. A machine includes the foregoing components to accomplish this method.

  • Patent number: 7179161
    Abstract: A machine and method for encasing sausages by having a stuffing tube that is vertically disposed in order to allow gravity to help in the sausage making process. A conical shaped restricting device is attached to the stuffing tube to help facilitate the movement of the casing into a twisting mechanism and to ensure bunching in the casing is reduced. The casing is then fed through the twisting mechanism and into a linker.

  • Patent number: 6846234
    Abstract: A stuffing tube for a meat encasing machine that has a hollow stuffing tube. The hollow stuffing tube also has an inner chamber that is fluidly linked to the exterior of the hollow tube by a series of openings located in the wall of the stuffing tube. The openings and chamber allow water connected to a water source to be pumped into the stuffing tube. This causes a lubricating water surface to accumulate on the exterior of the stuffing tube providing lubrication for a sausage casing. This lubrication facilitates the sliding movement of the casing longitudinally along the stuffing tube.

  • Patent number: 6843713
    Abstract: A method of advancing a sausage casing mounted on a stuffing tube into a twisting mechanism includes placing a hollow natural sausage casing on the outside surface of a stuffing tube and engaging the casing with a roller. The roller then forces the casing to slide toward the discharge end of the stuffing tube. The roller may be attached to an arm that has its height controlled by the rotation of a cam. By controlling the arm height the cam controls the feed pattern of the casing.

  • Patent number: 6719621
    Abstract: A method of stuffing natural casings with emulsion involves slidably mounting a collar element on the stuffing tube of the machine adjacent an end of the stuffing tube opposite to the discharge end thereof. The collar is slidably advanced towards the discharge end of the tube to telescope the casing into a shirred condition while leaving a non-shirred portion downstream thereof. The non-shirred portion of the casing is progressively advanced while the casing is filled with emulsion from the tube. A sensor is placed in the proximity of the non-shirred portion of the casing to detect whether shirred or non-shirred casing is present. The sensor is connected to a controller so that the collar will be advanced to slide the casing material on the tube when the non-shirred casing is detected, and the advance of the collar is stopped when shirred casing material is detected. A machine includes the foregoing components to accomplish the method.

  • Patent number: 6676502
    Abstract: A method and structure of stuffing natural casings with sausage material involves taking a plurality of natural casings of different lengths and diameters; pre-loading each of the casings on elongated hollow open ended sleeves shorter than the casings and having a diameter less than the casings by telescoping the casings on the outer surfaces of the sleeves, slidably mounting the sleeves on the open end of a meat stuffing tube of a sausage encasing machine; extruding meat emulsion through the stuffing tube into the casing mounted on the sleeve until the sleeve is slidably removed from the tube, removing the sleeve from the stuffing tube, repeating the use of the sleeve by preloading the sleeve with another natural casing.

  • Patent number: 6669545
    Abstract: A controlled follower on a stuffing tube engages and causes a natural casing thereon to be longitudinally moved toward the discharge end of a stuffing tube to be filled with emulsion, twisted and formed into links. The follower is controlled by a sensor, in conjunction with a controller, and in instances, influenced by a sensor, to have a controlled movement of the casing along the stuffing tube.

  • Patent number: 6659854
    Abstract: A method for rapid loading of casing-bearing sleeves on the stuffing tube of a sausage machine, provides for placing the preloaded sleeves on a feeder mechanism and selectively and sequentially moving the sleeves into registering position with the discharge end of an emulsion stuffing tube; sequentially moving the stuffing tube into each of the sleeves and extruding emulsion through the stuffing tube into the casing mounted on the sleeve until the sleeve is slidably removed from the tube caused in part by the movement of emulsion entering the casing. The apparatus has a fixture suitably movably mounted on the machine with a plurality of preloaded sleeves thereon for sequential movement for selective alignment of the sleeves with the stuffing tube for sequential filling of the casings with emulsion.
