Abstract: A method of cleaning an embossing roll used in an embossing process. The method includes steps of passing a paper web between a pair of embossing rolls and preventing or cleaning deposits from the surface of at least one embossing roll. Pressurized air is forced through an air nozzle having an elongated narrow outlet that directs the pressurized air as an air knife against the patterned surface of the embossing roll after the patterned surface rotates out of contact with the web. The air knife extends an embossing width of the embossing roll. A lubricant or solvent may be mixed with the pressurized air.

Abstract: An embossing roll cleaning apparatus is provided. The cleaning apparatus includes a nozzle having an air inlet and an elongated narrow outlet that extends an embossing width of the embossing roll. A source of compressed air is connected to the air inlet of the nozzle. The outlet of the nozzle directs the pressured air as an air knife against the surface of the embossing roll to dislodge deposits stuck to the surface of the embossing roll.

Abstract: A network system in which data is transferred through a bypass circuit which extends between the ends of a branch and becomes active when all the disk drives in the branch are inactivate, rather than the data being transferred through bypass circuits individually associated with the disk drives and which become active when the disk drives are inactive.

Abstract: A method is provided for cleaning a surface of an embossing roll in which the surface of the embossing roll is cleaned by directing pressurized air through an air nozzle as the embossing roll rotates. The air nozzle directs the pressurized air as an air knife that extends for the width of the embossing roll to clean the surface. A lubricant and solvent solution may be added to the air supply of the air nozzle to prevent deposits from sticking to the surface of the embossing roll and to dissolve any deposits that do stick to the surface of the embossing roll.

Abstract: An I/O interface for an integrated circuit (IC) is described that has a reduced number of I/O pins dedicated to providing control signals to or status information from the IC. In one embodiment, the IC comprises a plurality of input pins connected to logic for receiving and processing input data. The input pins have an input bandwidth greater than the logic's processing rate. If data and control signals are multiplexed onto the same input pin, the excess input pin bandwidth may used to transfer control signals into a plurality of latches within the IC. The I/O interface outputs a select signal that designates when an external device should drive the input pins with either data or control signals. In a specific embodiment, the logic comprises a parallel to serial converter and the control signal select conversion speed or encoding options. In another embodiment, the IC comprises a plurality of output pins connected to the output of a selector.
