A method of making a fabric-creped absorbent cellulosic sheet comprising: a) compactively dewatering a papermaking furnish to form a nascent web having an apparently random distribution of papermaking fiber; b) applying the dewatered web having the apparently random fiber distribution to a translating transfer surface moving at a first speed; c) fabric-creping the web from the transfer surface at a consistency of from about 30 to about 60 percent utilizing a patterned creping fabric, the creping step occurring under pressure in a fabric creping nip defined between the transfer surface and the creping fabric wherein the fabric is traveling at a second speed slower than the speed of said transfer surface, the fabric pattern, nip parameters, velocity delta and web consistency being selected such that the web is creped from the transfer surface and redistributed on the creping fabric to form a web with a drawable reticulum.

A method of making a cellulosic web includes: forming a nascent web from a papermaking furnish, the nascent web having a generally random distribution of papermaking fiber; b) transferring the web having a generally random distribution of papermaking fiber to a translating transfer surface moving at a first speed; drying the web to a consistency of from about 30 to about 60 percent including compactively dewatering the web prior to or concurrently with transfer to the transfer surface; fabric-creping the web from the transfer surface at a consistency of from about 30 to about 60 percent utilizing a creping fabric with a patterned creping surface, the fabric creping step occurring under pressure in a fabric creping nip defined between the transfer surface and the creping fabric wherein the fabric is traveling at a second speed slower than the speed of said transfer surface, the fabric pattern, nip parameters, velocity delta and web consistency being selected such that the web is creped from the transfer surface and redistributed on the creping fabric such that the web has a plurality of fiber-enriched regions arranged in a pattern corresponding to the patterned creping surface of the fabric, optionally drying the wet web while it is held in the creping fabric. Preferably, the formed web is characterized in that its void volume increases upon drawing.

A method of making linerboard with elevated CD strength includes: a) compactively dewatering a papermaking furnish to form a nascent web having an apparently random distribution of papermaking fibers; b) applying the dewatered web having apparently random fiber distribution to a translating transfer surface moving at a first speed; c) fabric-creping the web from the transfer surface at a consistency of from about 15 to about 75 percent utilizing a patterned creping fabric. The creping step occurs under pressure in a fabric-creping nip defined between the transfer surface and the creping fabric, wherein the fabric is traveling at second speed slower than the speed of the transfer surface and the fabric pattern, nip parameters, velocity, delta and web consistency are selected such that the web is creped from the transfer surface and distributed on the creping fabric. The fabric-creped web has an elevated CD strength as compared with the web prior to fabric-creping. The process further includes: d) wet-pressing the web after fabric-creping; and e) drying the web.

Systems and methods for controlling broadcast streaming media to a user's Internet-accessible device are disclosed. In one embodiment, a timeline temporally associating streaming media content programs from a plurality of Internet resources is created and sent to a server. After receiving a playback request form a user's device, the server accesses the timeline and identifies the address associated with a streaming media content program for the current time as indicated in the timeline. The server then sends across the Internet to the user's device the address of the program associated with the current time on the timeline. The user's device then accesses the broadcast streaming program and playback begins. At subsequent times, according to the timeline, the server will send a new address to the user's device that is indicative a program within the timeline. Thus, playback on the user's device is continuous and changes automatically according to the user's preferences as indicated in the timeline.

A supported davit arm extension assembly for a descent apparatus comprising an escape shuttle suspended from a cable defining a descent path from an initial point at a receiver of a platform to a terminal point proximate to a ground surface. The extension assembly comprises a davit arm extending above the platform and secured to the receiver, and a fall arrest trolley operatively coupled to the shuttle at a first end and terminating at a second end extending substantially away from the terminal point. The second end of the fall arrest trolley has a securement point for connection to and support of a load, such as a worker, by an overhead fall arrest. While the shuttle is docked with the receiver, the fall arrest trolley extends over the platform, supported by the davit arm, and facilitates substantially unfettered movement of the worker around the platform. As the worker enters the shuttle, it is disengaged from the receiver and follows the descent path of the cable toward the ground surface. The second end of the fall arrest trolley rides along the davit arm and onto the cable and is thereafter supported thereon through the descent of the shuttle.
摘要:
A method of making a fabric-creped absorbent cellulosic sheet is provided which includes dewatering a papermaking furnish and partially drying the web without wet-pressing before applying it to a translating transfer surface moving at a first speed. The process further includes fabric-creping the web from the transfer surface at a consistency of from about 30 to about 60 percent utilizing a creping fabric, the creping step occurring under pressure in a creping nip defined between the transfer surface and the creping fabric wherein the fabric is traveling at a second speed slower than the speed of said transfer surface, the fabric pattern, nip parameters, velocity delta and web consistency being selected such that the web is creped from the surface and redistributed on the creping fabric. After creping, the web is dried, preferably with a plurality of can dryers to a consistency of at least about 90 percent while it is held in the creping fabric.
