A manhole cover assembly includes a manhole cover supportable by a manhole frame. The manhole cover defines a latch bore having a longitudinal axis. A latch housing extends from the manhole cover, and a latch assembly is positioned at least partially therein. A first end of a latch yoke extends through the latch bore and slidably couples the latch yoke to the manhole cover along the longitudinal axis. A latch member is rotatably coupled to the second end of the latch yoke about a first transverse axis perpendicular to the longitudinal axis. The latch member is also rotatably coupled to the latch housing about a second transverse axis spaced from the first transverse axis. The latch member is selectively rotatable relative to the latch housing about the second transverse axis, between a locked position and an unlocked position, via sliding the latch yoke relative to the manhole cover.

This invention relates to an apparatus for transferring a discrete portion of a first web traveling at a first speed onto a second web traveling a second speed. The apparatus includes a converting mechanism capable of forming at least one discrete portion out of the first web. An anvil roll is positioned in close proximity to the converting mechanism and can travel at a rotational speed equal to the first speed. The anvil roll is a vacuum roll that is capable of directing the discrete portion away from the converting mechanism. A transfer roll is arranged in close proximity to the anvil roll and initially travels at a rotational speed equal to the first speed. The transfer roll forms a gap with the anvil roll through which the discrete portion can pass. The transfer roll is also a vacuum roll that is capable of directing the discrete portion away from the anvil roll. The transfer roll is capable of changing rotational speed to match the second speed during a single revolution. A backing roll is arranged in close proximity to the transfer roll and travels at a rotational speed equal to the second speed. The backing roll cooperates with the transfer roll to combine the discrete portion with the second web.

This invention relates to a method of transferring a discrete portion of a first web onto a second web. The method includes advancing the first web at a first speed and advancing the second web at a second speed. The first web is directed to a converting mechanism where a discrete portion is formed. The discrete portion is then transferred onto a vacuum anvil roll that is rotating at the speed of the first web. The method further includes transferring the discrete portion from the vacuum anvil onto a transfer roll that is also traveling at the first speed. The transfer roll is a vacuum roll that is driven by a servomotor and is capable of changing speeds quickly. The speed of the transfer roll is varied to match the speed of the second web and the discrete portion is transferred onto the second web.

A method and apparatus for forming an article ( ) includes a moving of a forming surface ( ) through an operative forming chamber ( ) along a forming path length ( ). A first fibrous stratum ( ) of fiber material ( ) can be deposited onto the forming surface ( ), and the first fibrous stratum ( ) can have a first stratum thickness ( ). A first quantity of a first superabsorbent material ( ) can be directed to form a selected combination with the first fibrous material to provide a first superabsorbent-containing stratum. A second fibrous stratum ( ) of fibrous material can be deposited to overlie the first fibrous stratum ( ), and the second fibrous stratum ( ) can have a second stratum thickness ( ). A second superabsorbent material ( ) can be directed to form a selected combination with the second fibrous material to provide a second superabsorbent-containing stratum.

A method and apparatus for depositing particulate material (,) in an airlaid fibrous web (,) includes a moving of a forming surface (,) through a forming chamber (,), and a laying of a fibrous material (,) onto the forming surface to form the fibrous web. The particulate material is delivered into the forming chamber with an arcuate curved nozzle (,) which is positioned within the forming chamber at a location spaced from the forming surface.
