摘要： This disclosure relates to a method for deaerating a liquid layer such as a coating solution using electrostatic forces. A flow of charged particles is created above and moved towards a low conductivity liquid layer. The flow of charged particles causes localized thinning of the liquid layer which facilitates the removal of bubbles of entrained gas from the liquid by bringing those bubbles closer to the exposed surface of the liquid and rupturing them at that surface. This electrostatic deaeration technique is combined with other non-electrostatic liquid layer thinning techniques or degassing techniques to further facilitate removal of bubbles from the liquid in preparation of further processing of the liquid. The liquid layer may be stationary or flowing with respect to the application of charge particles.

摘要： Multilayer meltblown fibrous webs, as well as apparatus and methods of forming the webs. The webs are produced on a rotating collector that also moves parallel to its longitudinal axis. The webs are thus formed in a helical process, and the resulting tubular web is separated in a direction parallel to a helix angle. By separating the tubular web in a direction parallel to the helix angle, a flat multilayer meltblown fibrous web is provided that allows for incorporation of feathered edges formed during the article's manufacture.

摘要： A coating device has a first half and a second half located adjacent the first half to form a slot between the first and second halves. A porous material, having a thickness greater than the height of the slot, is disposed in the slot to compress uniformly along its width. The porous material has a porosity and a height selected in combination with each other to create a predetermined pressure drop through the slot and to maintain the pressure drop to create the desired flow rate along the slot width. The size of the pores in the porous material can be less than 25 .mu.m and the exit pressure drop through the slot can be at least one thousand times greater than could be obtained without the porous material.

摘要： A system for applying a fluid coating onto a substrate includes forming a fluid wetting line by introducing a stream of fluid onto a first side of the substrate along a laterally disposed fluid-web contact area. An electrical force is created on the fluid from an effective electrical field originating from a location on the second side of the substrate and at a location substantially at and downstream of the fluid contact area. The electrical field can be generated in a highly effective manner relative to the coating fluid by a sharply defined electrode on the second side of the substrate. Ultrasonics combined with electrostatic fields further enhances coating process conditions and coating uniformity.

摘要： Microneedle devices and methods of manufacturing the microneedle devices. The microneedle devices include microneedles protruding from a substrate, with the microneedles piercing a cover placed over the substrate surface from which the microneedles protrude. The cover and the microneedle substrate together define a capillary volume in fluid communication with the base of each microneedle. One manner of using microneedle arrays of the present invention is in methods involving the penetration of skin to deliver medicaments or other substances and/or extract blood or tissue. Manufacturing methods may include simultaneous application of pressure and ultrasonic energy when piercing the cover with the microneedles.

摘要： An adjustable mounting system for premetered contact coating dies includes a base and a die-receiving portion movably connected to the base. During coating, the die can float a distance from the surface being coated based on the balance of forces between the die and the coated surface. This creates a variable separation gap and allows automatic self-compensating for variations in web or fluid properties. This, in turn, optimizes the coating characteristics. The mounting system can also include an enclosure for protecting its components.
