  • Patent number: 4907392
    Abstract: A machine for applying a twist-type tie to the neck of a bag has a path and sets of endless belts which come together at a nip along the path to propel a bag neck which passes into the nip forwardly to a typing zone in the path. Here a twist-type ribbon crosses the path and is secured at its end in a holder. An endless chain carries a pusher tab up to the tying zone behind the bag neck, causing the bag neck to gather behind and deflect the ribbon, then pauses, and thereafter resumes its forward motion to drive the bag neck out of the machine. During the pause a bag clamp secures the bag neck against a surface that is along the path and a needle lifts a portion of the ribbon upwardly behind the gathered bag neck and brings that portion of the ribbon to the holder so that the ribbon loops below the bag neck in the form of leading and trailing segments. While the needle is so extended, a twister hook gathers its leading and trailing segments and twists them together.

  • Patent number: 4901577
    Abstract: The web in a high speed printing press passes between a transmitter and receiver, the former of which produces ultrasonic sound which the latter receives, after attenuation by the web, and the latter of which converts the sound into an oscillating electrical signal of corresponding frequency. This electrical signal, after being amplified and filtered, is impressed upon a peak detector and a comparator. The peak detector produces a constant potential equal to the amplitude of the peaks in the amplified signal, and this constant potential is reduced a predetermined proportion and is applied to the comparator as a reference potential. The comparator compares the reference potential with the amplified oscillating signal. The reference potential remains undisturbed even though the oscillating signal may momentarily drop due to the further attenuation of the sound caused by a splice moving through it.

  • Patent number: 4900166
    Abstract: A taper roller bearing for a non-driven wheel of a vehicle has the annular cup member, which provides its outer raceway, formed with an axial extension over which the rim member of the wheel can be slipped to support and locate the rim while it is being engaged on the wheel studs and while the wheel nuts are placed in position. The extension has its outer end part which is to receive the rim formed slightly smaller external diameter than the main part of the cup. The cone member of the bearing, which provides the inner raceway, may have an axial extension projecting in the opposite direction to the extension of the cup to form a spacer between the bearing and second taper roller bearing disposed coaxially with or in the opposite sense to the first bearing.

  • Patent number: 4897926
    Abstract: A vehicle wheel turning angle gauge having a base to support a wheel engaging turnable plate which supports an optical encoder device mounted in non-rotary position so an operating shaft can engage and turn with the turnable plate to generate signals of the degree of turn and the direction of that turn. The base provides a structure for limiting the maximum displacement of the turnable plate without restricting its direction of motion so it will accommodate the range of vehicle wheel movement as required for alignment purposes.

  • Patent number: 4897356
    Abstract: This device brings microorganisms into contact with liquids as required, for example, in the treatment of sewage. The device comprises a hollow main shaft into which the inner ends of coiled process elements or process tubes are inserted and fixed. Each tube is coiled in increasing diameters at right angles around the shaft. The shaft is placed in a tank partially immersing the tubes such that when the shaft rotates the open end of each tube, into which liquid enters, alternatively passes through the liquid and the surrounding atmosphere, then the liquid, and so on. Liquid picked up during previous revolutions rotates through the tubes and eventually discharges into and through the hollow main shaft to a receiving wheel. In this way, discrete volumes of liquid pass sequentially through the tubes and are brought in contact with the microorganisms on the inner surface of the tubes.

  • Patent number: 4892046
    Abstract: A removable roof for a furnace in which metal is melted has a framework composed of a series of horizontal beams arranged in several layers, with the beams of the lowest layer being parallel to each other and being held in fixed and determined relation with respect to each other by the beams of the next layer. Anchors are attached to the beams of the lowest level, and a cast refractory fills the spaces between and around the anchors so that the refractory forms the downwardly presented face of the roof--the face which is exposed to the interior of the containment vessel. To construct the roof, the framework is fabricated and placed over a horizontal surface, whereupon the anchors are attached and a moldable refractory mix is introduced with the spaces between the anchors. The mix sets up into the refractory.

  • Patent number: 4891930
    Abstract: To protect a round bale of hay from moisture, the bale is engaged by a machine attached to the three point hitch of a conventional farm tractor and then elevated with the hitch. An impervious strip, which is supplied on a roll, is attached at its end to the bale near one end of the bale, and then the machine rotates the bale, causing the strip material to pay off of the roll and wrap around the bale. The roll, which is on a dispenser, is maneuvered along the bale such that the strip wraps spirally around the bale with some overlap between adjacent convolutions of the strip. This forms a sleeve-like cover around the bale for the entire length of the bale. The machine includes a frame which connects to the three point hitch of the tractor and has a horizontal bearing in which a spear shaft rotates. The shaft is quite long and solid, so that as it rotates it may be driven into the bale from one end of the bale.

  • Patent number: 4887502
    Abstract: A machine for slitting metal sheet has a bridge-type frame provided with upper and lower beams supported on posts. In the space between the two beams are upper and lower powered arbors and also upper and lower storage arbors which align respectively with the upper and lower powered arbors. Each powered arbor supports and turns several knives which are mounted on hubs along those arbors, and these knives when not needed may be moved, along with their hubs, onto the aligned storage arbors. Each knife is captured in a carriage which moves along one of the beams and contains back-up rollers which bear against the knife to prevent its arbor from deflecting under the spreading force exerted by the metal sheet as it is slit. The hubs have a wide stance, and accordingly the knives on them do not acquire a wobble when the hubs are secured on their respective arbors; yet notwithstanding the wide stance, the knives may be brought quite close together.

  • Patent number: 4884786
    Abstract: A furnace maintains metal in a molten condition as a melt, and part of the melt is exposed in a charging well where lightweight solid scrap is introduced into the furnance. A vortex generator imparts a vortex to the melt within the well, so that lightweight solid scrap is quickly submerged in the well. The vortex generator includes an impeller which rotates within the well and actually creates the vortex. In addition, it has an elevator from which the impeller is suspended as well as a drive motor for turning the impeller, with the motor being on the elevator. An elevator frame serves to guide the elevator and the elevator frame is in turn connected to a trolley which runs along a track that passes over the charging well, but also extends well beyond it.

  • Patent number: 4881346
    Abstract: A barn door includes vertical members at its ends and lateral members extended between the vertical members which the vertical and lateral members being interlocked where they meet. To this end, the vertical members are channel-shaped, each having a front and a rear wall along with a end wall that connects the front and rear walls, it being formed integral with both. Each vertical member has vertical ribs which project toward each other from its front and rear walls. The lateral members, on the other hand, have vertical slots in their side walls. The ribs of the vertical members snap into the slots of the lateral members and this interlocks the vertical and lateral members. The joints so formed are rendered more secure with screws which pass through the front and end walls of the vertical members and into the side walls of the lateral members. A siding material is attached to the lateral members and at its ends projects under a lip on the front walls of the vertical members.
