Microperforated polymeric film for sound absorption and sound absorber using same

Abstract: Microperforated polymeric films and sound absorbers using such films are provided. The microperforated polymeric films may be relatively thin and flexible and may further include holes having a narrowest diameter less than the film thickness and a widest diameter greater than the narrowest diameter. The microperforated polymeric films of a sound absorber may also have relatively large free span portions, which, in certain embodiments, may vibrate in response to incident sound waves.

Urinary incontinence stimulator system

Abstract: A urinary incontinence stimulator system using an intra-anal electrode which provides a recurring series of pulses of varying duration and frequency to the electrode with each of such series of pulses spaced from the succeeding series by a rest period when no pulses are provided to the electrode.

Microwave food package and grease absorbent pad therefor

Abstract: A package of food containing a substantial amount of water and solidified grease that can be cooked within the package in a microwave oven. A pad adjacent the food comprises microwave radiation transparent generally hydrophobic liquid grease absorbing materials that are capable of holding the amount of grease in the food when it is melted; and a vapor tight microwave radiation transparent enclosure surrounding the pad and food includes means for venting steam from the enclosure as the food is cooked. Preferably, the pad is produced from microfibers constructed of a composition comprising a blend containing substantially equal parts by weight of polypropylene and poly 4-methylpentene-1.

Radiation curable abrasive article with tie coat and method

Abstract: A method of preparing an abrasive article, and the article produced therefrom is provided. The method includes the steps of: providing a backing having a first major surface; coating the first major surface of the backing with a tie coat precursor, wherein the tie coat precursor comprises a first radiation curable component; applying an abrasive slurry to the first major surface of the backing after coating the tie coat precursor thereon, wherein the abrasive slurry comprises a plurality of abrasive particles and a binder precursor, and further wherein the binder precursor comprises a second radiation curable component; at least partially curing the tie coat precursor; and at least partially curing the binder precursor to form an abrasive article, wherein the abrasive article comprises a backing, an abrasive layer, and a tie coat disposed between the backing and the abrasive layer. Preferably, the method provides a structured abrasive article.

Sensors based on nanosstructured composite films

Abstract: An electrically reactive composite article comprising a random or regular array of microstructures partially encapsulated within an encapsulating layer, microstructures each comprising a whisker-like structure, optionally having a conformal coating enveloping the whisker-like structure is described. The composite article is useful as an electrically conducting component of a circuit, antenna, microelectrode, reactive heater, and multimode sensor to detect the presence of vapors, gases, or liquid analystes.
