  • Patent number: 5632594
    Abstract: The machine for ordering textile tubes for entry into the distributor of a continuous spinning machine includes mechanisms that perform that ordering so that, independently, the textile tubes can be delivered to one side or the other of the spinning machine and devices for ordering tubes of different dimensions automatically. The ordering machine has a hopper, containing textile tubes, two parallel vertical conveyor belts provided with textile tube holders for the tubes which move the tubes from one end at the hopper to another end remote from it, a bottom discharge device for feeding the ordered tubes to the spinning machine and lateral guides for guiding the tubes to the bottom discharge devices. The textile tube holders are advantageously rubber sections vulcanized onto the conveyor belt of various transverse cross-sections or metallic angular sections fastened to the conveyor belts.

  • Patent number: 5584636
    Abstract: A break-out attachment (2) configured for connection to a vehicle, such as a lift truck (20), for retrieving, transporting and releasing cotton bales. The break-out attachment comprises a shaft (24) rotatably mounted to a base frame (4), two lower horizontally spaced support arms (10, 12) extending outward from the shaft for supporting a cotton bale and an upper arm (6) extending from the shaft between the support arms for engaging the cotton bale. A rotary actuator (52) is coupled to the shaft for rotating the shaft and the three arms around the longitudinal axis of the shaft. The upper arm has a hydraulic cylinder (88) for telescoping toward and away from the shaft. The hydraulic cylinder provides more flexibility in the positioning of the truck and allows the operator to initially engage the cotton bale with only the upper arm, thus facilitating the process of retrieving the bale.

  • Patent number: 5575612
    Abstract: An apparatus for stacking bundles of sheets includes an elongate stacking table capable of movement upwardly and downwardly, the stacking table being lowered in accordance with an increase in stacking amount of the bundles of sheets. A single-side-openable type shutter member is located above the stacking table and is adapted to support the bundles of sheets arranged in a row, the shutter member being capable of opening only in the direction perpendicular to the direction of the bundles of sheets being arranged in a row, so that the bundles of sheets are simultaneously dropped onto the stacking table. A stationary ruler member is adapted to restrict only one side surface of the bundles of sheets at the openable side of the shutter member and prevent the bundles of sheets from movement following the opening action of the shutter member so that the bundles of sheets are dropped to a predetermined location.

  • Patent number: 5575536
    Abstract: A dump truck spreads material to form a layer of material to form a structure such as a road by tilting a dump body pivoted on the truck and allowing a tailgate to open a gap through which the material flows as the dump truck moves forward. Typically, a pair of chains determine the width of the gap. In order to release the chains and allow the tailgate to swing freely if the material becomes jammed and does not freely flow through the gap, a pair of toggle-type chain releases are provided. The toggle-type chain releases comprise chain-retaining plates with slots therein for receiving one link of the chains. The retaining plates are rotatable from a chain-retaining position to a chain-releasing position. The toggles which operate the chain retaining plates include levers which are unitary with one link of the toggles and serve as operating handles which when pulled releases the chains.

  • Patent number: 5570993
    Abstract: A component mounting device adapted to mount components such IC or the like on a printed circuit board that includes replaceable pick up nozzles to accommodate different types of components to be picked up. A sensing station is provided that permits the pick up nozzle to be verified as the correct one and also to determine, if desired, its orientation and misalignments in its axis of rotation so as to permit adjustment in the mounted to accommodate for errors. In addition, a reference height position may be set so that the same sensing station can be employed to sense both the orientation of a component that is picked up and also whether the component is correctly oriented for deposit. This is done by measuring projected lengths in a plane with a photo sensitive device and by making calculations in accordance with trigonometric relationships.

  • Patent number: 5569015
    Abstract: An intermediate storage apparatus for the storage of sheets has an acceptance cycle and a transportation cycle and includes a feed system and a transportation system. In the acceptance cycle the intermediate storage apparatus waits until a first detector detects the presence of a sheet at an entry and triggers off an acceptance operation in the feed system by way of a control device. The feed system stacks the sheets which are fed by a conveyor system to provide a stack in the transportation system which is locked in the acceptance cycle. As soon as the acceptance cycle is concluded, the control device decides whether the transportation system is to pass the stack into a box or into a return dish and switches on a drive unit of the transportation system to transport the stack. The intermediate storage apparatus then returns to the acceptance cycle.

  • Patent number: 5568855
    Abstract: A coin detection and identifying apparatus and method, utilizes three closely aligned electric coils. The center coil is actively driven by an alternating current to generate a magnetic field that surrounds the center coil. The two outer coils are symmetrically disposed within the magnetic field generated by the center coil, and voltages are induced across the terminals of the outer coils which are indicative of the relative field strengths of the magnetic fields within the outer coils. A sample coin and test coin are interposed between the center coil and each of the outer coils, the coins operative to attenuate the surrounding magnetic fields. A controller compares the voltages across the terminals of the two outer coils to effectively compare the likeness of the sample and test coins. A coin sensing apparatus, located downstream of the coils, provides a plurality of optic emitter-detector pairs to detect the valid passage of a coin.

  • Patent number: 5566799
    Abstract: Low aerodynamic noise type current collection equipment is provided for reducing variations in aerodynamic force applied to a current collector during train operation. A central region (2a) of a current collector (1) having a collector head (2) with a top surface in which a contact strip (3) is embedded is rectangular in cross-section, and each side region is shaped convex in cross-section in the front and rear directions, with e.g. an elliptical shape. The rectangular shape has characteristics such that the magnitude of the aerodynamic lift force would be kept substantially constant even if the inclination angle against the aerial flow would be changed.

  • Patent number: 5567107
    Abstract: A device has a sliding tube assembly which can be mounted to a motor vehicle. The tube assembly has three tubes which coaxially telescope between a lowered loading/unloading position and either a raised storage position or a raised loaded position. A pivotable platform attached to the tube assembly is controlled by a logic mechanism which senses whether cargo is present on the platform. If cargo is present, the platform may be raised and a locking mechanism secures the cargo to the platform. If no cargo is present as the platform is raised, it pivots into a folded storage position and is held securely by the locking mechanism. When the platform is in one of the two raised positions, the tube assembly and platform tilt forward. The device is driven by a motor activated linear actuator extending down through the tube assembly. A control system governs operation of the device.
