  • Publication number: 20190366867
    Abstract: There is provided an electrically-powered material-transport vehicle having a vehicle-charging contact on one side of the vehicle, and a second vehicle-charging contact on the opposite side of the vehicle. The vehicle has a load-bearing cap that covers the top of the vehicle, and a cap elevator for raising and lowering the cap. The cap can be raised and lowered to a transit position, a payload-engagement position, a charging position, and a maintenance position. In the transit position and payload-engagement position, the cap covers the vehicle-charging contacts so that they are not exposed. In the charging position, the cap is raised so that the vehicle-charging contacts are exposed. The vehicle can enter a charging-dock with the cap in the charging position in order to recharge the vehicle's battery.

  • Patent number: 10428301
    Abstract: Oscillating angularly rotating a container containing a material may cause the material to be separate. Denser or heavier material may unexpectedly tend to collected relatively close to the axis of rotation, while less dense or light material may tend to collect relatively away from the axis of rotation. Oscillation along an arcuate path provides high lysing efficiency. Alternatively, a micromotor may drive an impeller removably received in a container. Lysing may be implemented in batch mode, flow-through stop or semi-batch mode, or flow-through continuous mode. Lysing particulate material may exceed material to be lysed or lysed material and/or air may be essentially eliminated from a chamber to increase lysing efficiency.

  • Publication number: 20190224010
    Abstract: A delivery system for an implantable medical device includes an outer shaft and an inner shaft translatable within the outer shaft. An internally exposed coil is disposed within the inner shaft and is electrically coupled to an externally exposed coil that can be used to inductively transmit a current flowing through the internally exposed coil. An actuation member extends within the inner shaft and includes a coupler, a force translation rod that extends proximally from the coupler and a plurality of push pull rods that extend distally from the coupler and that releasably couple to the implantable medical device. As the force translation rod moves relative to the internally exposed coil, an impedance varies in accordance with relative position.

  • Patent number: 9203346
    Abstract: An apparatus and method for sensing load current of an envelope tracking (ET) modulator enables load impedance of a power amplifier to be measured. Impairments associated with the load impedance characteristic can be suppressed by calibration and predistortion instead of by feedback (as done in the prior art). The ET modulator provides a switching regulator that can be reconfigured as a linear regulator for the purpose of sensing the load current. This allows the ET modulator to be operated open-loop, thereby eliminating the power consumption overhead resulting from utilization of a loop filter and error amplifier (used in the prior art) and achieving a higher overall efficiency.

  • Patent number: 4753429
    Abstract: A collating station is disclosed for a machine intended to insert first and second documents into an envelope. Prior to the insertion operation, the first and second documents are advanced serially in a common plane. At a predetermined location, each first document is intercepted and lifted above the common plane and moved to a holding platform spaced above the common plane. The holding platform has a transverse terminal edge downstream from where the first document comes to rest. Thereupon, the first document resting on the holding platform and a following second document which continues to advance along the common plane as the first document travels toward the holding platform are advanced together in a parallel spaced relationship, toward a downstream station. As the documents are advanced, the first document drops off the terminal edge of the holding platform and onto the second document thereby completing the collating operation.

  • Patent number: 4733359
    Abstract: A document collating and inserting system having displays for document count verification. A plurality of bank checks belonging to a check set are fed, counted and stacked at a stacking station while simultaneously an associated statement is fed to an imaging station where a number imprinted thereon is imaged by a video camera and displayed on a video monitor. The number represents a predetermined number which should equal the actual number of checks counted, the actual count also being displayed. An operator makes a visual comparison of the two displayed numbers and, if they are in agreement, initiates a cycle of the system thereby forming a collation of the statement and checks and transporting them to a holding station. From the holding station the collation is inserted within an envelope provided by an envelope feeder during the next cycle of the system. If the two numbers are not in agreement a mismatch switch is provided for the operator to activate before cycling the system.

  • Patent number: 4728095
    Abstract: An improved separator assembly for document feeders comprises a retarding roller and a cooperating opposed feed roller. The retarding roller is selectably rotatable into orientations such that the selected one of a plurality of different peripheral portions of the retarding roller will be oriented into operative position with respect to the feed roller. The retarding roller includes at least one cylindrical portion and another portion which has an interfering member projecting outwardly from the roller. Other surfaces of the retarding roller may comprise different materials in order to avoid scratches on the documents to be fed or to change the frictional force on the documents.

  • Patent number: 4688708
    Abstract: A bursting machine is provided for separating discrete sheets from a continuous strip of sheets having uniformly spaced perforation lines across the width of the strip. A gauging device with numerical increments in the form of a linear scale is manually compared to the length of the discrete sheets to provide a predetermined number corresponding to a pulse count for entering into a control device through a manually settable device. The control device in turn is operatively connected to an electronic pulse counter. When the leading edge of the strip advances a predetermined increment after passing through a sensing device located downstream in the path of travel with respect to a first pair of feed rollers, a pulse generator attached to the driven first feed roller is actuated to generate pulses for counting to reach the preset number in the pulse counter.

  • Patent number: 4640506
    Abstract: An improvement in a collating machine for stacking sheets of paper being fed seriatim thereto from a singulating feeder in the same order as the sheets appear in the singulating feeder. The collating machine includes a belt for transporting the sheets of paper, a ramp for lifting a succeeding sheet of paper over and onto a preceding, stopped sheet of paper, and a stopping device for stopping each sheet of paper after the sheet has been lifted by the ramp. The improvement includes a removable stacking device for stacking the sheets of paper in the reverse order as the sheets appear in the singulating feeder.

  • Patent number: 4548393
    Abstract: A stopping mechanism in an inserting machine having a feeder for feeding documents seriatim to a transport deck therebelow, the feeder being angled with respect to the deck. The stopping mechanism stops the documents at a predetermined position with respect to a previously collated package situated on a ramp located upstream of the deck and elevated with respect to the deck. The stopping mechanism comprises a pivotable paddle located downstream of the feeder substantially parallel to the direction of feed, a device for biasing the lower end of the paddle away from the transport deck to permit a collated package to pass therebelow without contacting the pivotable paddle, and a device for pivoting the lower end of the paddle downward adjacent the transport deck for a short period of time at an appropriate moment in order to stop the forward motion of a document exiting the feeder at a predetermined position on the transport deck.
