Abstract: A power terminal block that accommodates busbars with various lengths and terminal positions is provided. The power terminal block includes a pair of insulators and a busbar. Each insulator includes a base, a shelf, and an insulating partition. The shelf is coupled to the base and is configured with a busbar mounting stud. The insulating partition is coupled to the base and the shelf. The busbar is configured to attach to the busbar mounting stud in each insulator. The insulators are spaced apart at a predetermined distance to receive a busbar of any length.

Abstract: A coater and a method of operating such coater is disclosed. The method of operating the coater includes the steps of separating a first tail from a full width web unwound from an unwind stand at threading velocity and threading the first tail at the threading velocity through a pull stack. The first tail is widened to the full width of the web so that a full width web extends through the pull stack. The full width web emerging from the pull stack is dumped into a first broke chute which is disposed below the pull stack. The full width web extending through the pull stack is accelerated along with a coating apparatus to coating velocity so that both the full width web and the coating apparatus attain coating velocity. A second tail is cut in the full width web between the unwind stand and the pull stack and such second tail is threaded through the coating apparatus while the second tail is moving at coating velocity.

Abstract: A press apparatus is disclosed for pressing a moving web formed on a forming wire. The apparatus includes a frame and a first plurality of rolls rotatably secured to the frame. A first continuous felt extends around the first plurality of rolls which include a pickup roll disposed adjacent to the wire for transferring the web from the wire onto the first felt. The first plurality of rolls also includes a first press roll which is disposed downstream relative to the pickup roll. A second continuous felt extends around a second plurality of rolls with the second felt cooperating with the first felt. The second plurality of rolls includes a second press roll which cooperates with the first press roll for defining therebetween a first nip. The web is urged against the second felt when the web emerges from the first nip and the second felt and supported web pass through a second nip defined by an extended nip press disposed downstream relative to the first nip.

Abstract: Extended nip presses for papermaking machines and the like are provided with electromagnets immediately adjacent the press nip to create or augment the nip pressures or loads. The electromagnets have massive, wide large areas, establishing a concentrated magnetic field between conforming opposite sides of the entire nip area eliminating gaps heretofore encountered in magnetic presses. Non-magnetic belts convey wet webs through the nips of dewatering presses and dry web calendering presses can have the webs directly engage a calender roll conveying the web through the nip.

Abstract: A control apparatus for controlling the differential pressure between steam inlet and outlet lines of a web dryer and includes a selectively controllable outlet valve disposed in the outlet line for selectively controlling the flow of blow-through steam, condensate and non-condensible gases out of the dryer. A dryer speed sensor generates a first control signal and a condensing rate sensor senses the rate at which a layer of condensate builds up within the dryer. The condensate rate sensor generates a second control signal. A control device is operably connected to an outlet valve actuator for selectively energizing the actuator in response to the first and second control signals. The control device compares the signals to determine the optimum relative setting of the outlet valve so that flooding of the dryer with condensate is inhibited while the differential pressure between the inlet and outlet lines is maintained as low as possible.

Abstract: An apparatus is disclosed for assisting the transfer of a web disposed contiguous relative to a transfer felt such that the web is transferred from a lead-in roll disposed adjacent to a press section to a first dryer of a papermaking machine dryer section. The apparatus includes an intermediate support roll disposed between the lead-in roll and the first dryer such that the transfer felt is disposed between the web and the intermediate roll. A first transfer box is disposed between the lead-in roll and the intermediate roll such that the transfer felt is disposed between the web and the first transfer box. The first transfer box is oriented relative to the transfer felt such that a partial vacuum is generated between the first box and the transfer felt for drawing the web into close conformity with the transfer felt between the lead-in roll and the intermediate roll.

Abstract: A sealing device is disclosed for sealing a securing device (17) which extends through adjacent flanges (7,9) of a shell (1) and of a head (3) of a fluid container. The sealing device includes an O-ring seal (23) which slidingly engages the securing device (17) for sealing the securing device relative to the flange (9) of the head. A carrier member (25) through which the securing device extends is urged towards the flange (9) of the head such that the O-ring seal (23) is urged into sealing engagement between the securing device (17) and the flange (9) of the head. The carrier member (25) defines a conical recess (35) for reception therein of the O-ring seal (23) such that when the carrier member (25) is urged towards the flange (9) of the head, the O-ring seal (23) is distorted by reaction between the carrier member (25), the securing device (17) and the flange (9) of the head so the securing device (17) and the flange (9) of the head are sealed relative to each other.

Abstract: A blow box (40) is disclosed which is disposed within a pocket (26) defined by a web (W) and felt (F) travelling together from a first dryer (12) to and around a second dryer (14) and onto and around a third dryer (16). The blow box (40) includes a wedge-shaped box extending from between the first and third dryers (12 and 16) to adjacent the second dryer (14), the box (40) being connected to a source of pressurized air (42) for maintaining the web (W) in close conformity with the felt (F) when the web and felt diverge relative to the first dryer (12). The box (40) defines an orifice (44) which is disposed adjacent to the first dryer (12) for directing pressurized air against the felt and then redirecting the air in a direction opposite to the direction of rotation of the first dryer (12) such that the web is urged against the felt for inhibiting the tendency of the web to adhere to the first dryer (12) when the felt diverges relative to the first dryer (12).
