  • Patent number: 6257824
    Abstract: A fin alternating and delivering apparatus is provided for orientating and delivering fins emanating from a fin mill to a fin trayer for assembly into a heat exchanger. The fin alternating and delivering apparatus includes an entrance chute for receiving fins emanating from the fin mill in a horizontal position. The fin alternating and delivering apparatus also includes a sensor disposed adjacent the entrance chute to sense the fins entering the entrance chute. The fin alternating and delivering apparatus includes an air jet operatively connected to the sensor for delivering a blast of air to the fins upon sensing the fins entering the entrance chute to reorientate the fins from the horizontal position to a vertical position. The fin alternating and delivering apparatus further includes a discharge chute disposed adjacent the entrance chute for guiding the fins from the entrance chute to the fin trayer in the vertical position.

  • Patent number: 6257818
    Abstract: A tree skidder transport machine and method wherein the machine has a hydraulically operated boom assembly extending rearwardly of a chassis. The boom assembly includes a main boom and a stick boom which cooperate hydraulically to lift the bottom end of a tree, or tree bunch, near the butt, and drag it forwardly over a bogied pair of chassis support wheels. With the further cooperation of a hydraulically actuated heel boom, the tree or tree bunch is then rotated vertically in a counterclockwise direction to lift its top end off the ground and move the tree or tree bunch forwardly a sufficient distance to bring some of the weight of the tree or tree bunch onto the front wheels of the machine.

  • Patent number: 6254332
    Abstract: The present invention discloses a nut feeder for the feeding of nuts for resistance welding. A stopper 12 is provided which is so energized as to enter into the inside of a chute 7 from a lower-end lateral side of the chute 7. A lowermost nut 5 in the chute 7 is held by the stopper 12, thereby being prevented from falling. With a pin 11 of the nut receiver 9 set against a projection part 29 of the stopper 12, a nut receiver 9 is moved backward together with the stopper 12, by which the holding of the nut 5 is released. Then the nut 5 is placed at a position ahead of the pin 11 of the nut receiver 9 while leaning against the stopper 12. Thereafter the nut receiver 9 is moved forward and the nut 5 falls down so that its threaded hole fits onto the pin 11 and is delivered to under the upper electrode.

  • Patent number: 6241449
    Abstract: A receiving frame, mounted on a horizontal platform includes a sub-frame that is tiltable, with respect to the platform, and has an elevator and elevator platform on its rear wall. The receiving frame receives a stack of tiers of plastic containers on a pallet. The pallet is positioned on the elevator platform. The sub-frame tilts 30 degrees off the vertical, out the open back of the receiving frame. A cover and tier sheet gripping device is provided, located above the top of the sub-frame, for securing and removing the top cover and tier sheets from the stack of tiers on the pallet, on the elevator platform. With the sub-frame tilted at 30 degrees off vertical, the elevator incrementally lifts its platform so that the base of the containers in the top tier and adjacent the rear wall of the sub-frame are at level with the top of the rear wall.

  • Patent number: 6241460
    Abstract: Envelopes in a vertical orientation are delivered in sequence to an envelope bundling table from a sheet insertion table where sheets are inserted into envelopes. A stationary vertical wall forms a part of the envelope bundling table and the respective short ends of envelopes of a preselected bundle of envelopes successively abut it when discharged onto that table. A movably mounted vertical wall has a first deployed configuration where it is disposed parallel to the first vertical wall, between the sheet insertion table and the stationary vertical wall. When so deployed, the envelopes of a preselected bundle successively abut it and therefore do not reach the first vertical wall. Those envelopes are therefore laterally offset from envelopes of a different bundle that abut the first vertical wall. The movable vertical wall has a retracted position so that envelopes delivered to the envelope bundling table abut the first vertical wall when the second vertical wall is retracted.

  • Patent number: 6238175
    Abstract: Foil sheets are removed from two stacks located one above the other on a stack rack by a swingable transfer assembly having a transfer platform along the sides of which guide rails carry a suction beam which, as the transfer assembly is swung up and down, can engage the uppermost foil sheet on one or the other stack. The suction beam draws the foil sheets onto the transfer platform where the foil sheet is oriented or aligned and from which the foil sheet is drawn onto a deposition station which can have belts carrying the laminate or in a direction orthogonal to the destacking transfer direction.

  • Patent number: 6238160
    Abstract: An electrically conductive workpiece such as a semiconductor wafer or the like is transported between a staging area and an electrostatic chuck within a processing chamber using an electrostatic arm. The arm is used to apply an electrical charge to the wafer and to hold the wafer during transport by means of an electrostatic force of attraction between the arm and the wafer. The arm also pre-charges the wafer in preparation to be electrostatically chucked within the processing chamber. Pre-charging the wafer eliminates the need for using a gas plasma within the chamber for chucking and dechucking the wafer.

  • Patent number: 6231299
    Abstract: An apparatus for forming vertical stacks of documents and then conveying the stacks serially along a conveyor to further processing stations. The stacks are rapidly ejected onto a conveyor which is driven at a relatively slow delivery speed, and to avoid longitudinal shingling of the stacks caused by their rapid ejection onto the conveyor, and to correct any lateral misalignment of each stack, there is provided a pair of rotatably mounted resilient guide rolls along respective opposite sides of the conveyor for rotation about vertical axes. The rolls are spaced apart a distance such that the rolls resiliently engage the opposite sides of the stacks as they pass therebetween. Also, the guide rolls are rotated at an initial peripheral speed which closely approximates the speed of the advancing stacks when the stacks engage the two guide rolls, which serves to square the stacks.

  • Patent number: 6231290
    Abstract: A processing unit for a substrate comprises a partition 6 provided between an atmospheric area S1 and an inert gas area S2. The partition 6 has an opening 22 to communicate the atmospheric area S1 and the inert gas area S2. A door 23 is provided at the opening 22 to open and close it. Carrier holding device 11 is provided for holding a carrier 2 of the substrate in such a manner that the carrier 2 comes in contact with the opening 22 on the side of the atmospheric area. Inert gas replacing device 56 is provided for replacing a gas in the carrier 2 with an inert gas by introducing the inert gas into the carrier 2 when the door 23 closes the opening 22 and the carrier 2 comes in contact with the opening 22 on the side of the atmospheric area by the carrier holding device 11. This processing unit can perform the process of the substrate without increasing the concentration of the oxygen in the inert gas area S2 by preventing leakage of the air from the atmospheric area S1 into the inert gas area S2.
