Methods and apparatus for intermittent rotary ultrasonic bonding system
InactiveUS6123792AAvoids deleterious bounceExtended service lifeLaminationLamination apparatusFiberSurface velocity
This invention relates to apparatus and methods for intermittently bonding a substrate web in fabricating a blank subassembly for an absorbent article. The invention comprises ultrasonic bonding apparatus including an anvil roll, a substrate web thereon, and at least one rotary ultrasonic horn. The substrate web can comprise at least first and second layers of material. The rotary ultrasonic horn, in combination with the anvil roll, ultrasonically bonds intermittent segments of the first and second layers of the substrate web to each other. Such intermittent bonds can comprise end seals for the absorbent articles. The ultrasonic horn and anvil roll are periodically separated from each other to provide the intermittent bonding of the substrate web. An actuator apparatus periodically moves the anvil roll and ultrasonic horn from engaging contact with each other preventing bond formation. The actuator apparatus can include a cam mechanism moving one of the anvil roll and ultrasonic horn from engaging contact with the other during rotation of the rotary ultrasonic horn. The cam mechanism can create a physical gap between the ultrasonic horn and the anvil roll. The cam mechanism moves either the ultrasonic horn and the anvil roll toward the other of the ultrasonic horn and anvil roll at a velocity of no more than about 80 millimeters / second to prevent bounce or impact loading when the horn and anvil roll are in engaging contact. The anvil roll comprises a substrate-receiving surface generally moving the substrate web through the nip at a surface speed of at least 300 meters per minute. The ultrasonic system generally creates bonds between the first and second layers of the substrate web at least about 600 times per minute.

Nonwoven composite containing an apertured elastic film
ActiveUS20080095978A1Lamination ancillary operationsSynthetic resin layered productsEngineeringBond formation
An elastic nonwoven composite that contains an elastic film laminated to one or more nonwoven web materials is provided. The composite is formed by passing the film through a nip to bond the film to the nonwoven web material(s). Concurrent with bond formation, apertures are also formed in the elastic film. The apertures are of a size sufficient to provide a desired level of texture, softness, hand feel, and / or aesthetic appeal to the composite without having a significant adverse effect on its elastic properties. Aperture and bond formation are accomplished in the present invention by selectively controlling certain parameters of the lamination process, such as film content, bonding pattern, degree of film tension, bonding conditions, etc.

Solid proppants are coated with a coating that exhibits the handling characteristics of a pre-cured coating while also exhibiting the ability to form particle-to-particle bonds at the elevated temperatures and pressures within a wellbore. The coating includes a substantially homogeneous mixture of (i) at least one isocyanate component having at least 2 isocyanate groups, and (ii) a curing agent comprising a monofunctional alcohol, amine or amide. The coating process can be performed with short cycle times, e.g., less than about 4 minutes, and still produce a dry, free-flowing, coated proppant that exhibits low dust characteristics during pneumatic handling but also proppant consolidation downhole for reduced washout and good conductivity. Such proppants also form good unconfined compressive strength without use of an bond activator, are substantially unaffected in bond formation characteristics under downhole conditions despite prior heat exposure, and are resistant to leaching with hot water.

Method and apparatus for muscle function measurement
The present invention provides an apparatus and method for monitoring muscle function based on an index derived from a pressure or force signal. The muscle function index is derived from an instantaneous muscle stiffness ratio computed as the ratio of the first time derivative of the pressure or force waveform to the corresponding instantaneous pressure or force. The instantaneous stiffness ratio, {dot over (E)} / E(t), is in units of 1 / sec and relates to the rate of strong bond formation and will be influenced by calcium handling properties of the muscle fibers and the intracellular calcium concentration. As such, an index derived from {dot over (E)} / E(t) provides a measure of the inotropic status of the muscle.
