摘要： An ultrasonic apparatus and method for regulating the flow of a pressurized liquid through an orifice by applying ultrasonic energy to a portion of the pressurized liquid. The apparatus includes a die housing which defines a chamber adapted to receive a pressurized liquid and a means for applying ultrasonic energy to a portion of the pressurized liquid. The die housing further includes an inlet adapted to supply the chamber with the pressurized liquid, and an exit orifice defined by the walls of a die tip. The exit orifice is adapted to receive the pressurized liquid from the chamber and pass the liquid out of the die housing. When the means for applying ultrasonic energy is excited, it applies ultrasonic energy to the pressurized liquid without applying ultrasonic energy to the die tip and modifies the flow rate of the pressurized liquid the exit orifice. The method involves supplying a pressurized liquid to the foregoing apparatus, applying ultrasonic energy to the pressurized liquid but not the die tip while the exit orifice receives pressurized liquid from the chamber to modify the flow rate of the pressurized liquid through the exit orifice, and passing the pressurized liquid out of the exit orifice in the die tip at the modified flow rate.

摘要： A method for forming microapertures in a thin sheet material where the area of each of the formed apertures generally ranges from about 10 square micrometers to 100,000 square micrometers. The method includes the steps of (1) placing the sheet material on a pattern anvil having a pattern of raised areas wherein the height of the raised areas is greater than the thickness of the sheet material; (2) conveying the sheet material, while placed on the pattern anvil, through an area where a fluid is applied to the sheet material; and (3) subjecting the sheet material to a sufficient amount of ultrasonic vibrations in the area where the fluid is applied to the sheet material to microaperture the sheet material in a pattern generally the same as the pattern of raised areas on the pattern anvil.

摘要： A method of treating a low hydrohead fibrous porous web material to increase its retentive wettability, by at least about 50%, as compared to untreated low hydrohead web material, is disclosed. The increase in retentive wettability is evidenced by the increase in the average number of runoff tests that the treated web material can sustain without unacceptable runoff is disclosed.The invention is also directed to products prepared or preparable by the process.

摘要： A programmable and automated leak detection apparatus performs automated handling and leak testing of varying sized objects. In one embodiment, the apparatus seals one portion of the object to form an inner chamber and also forms an enclosure about the entire object. Different partial vacuums are drawn on the chamber and the enclosure and a test gas injected into the enclosure. The chamber is monitored for test gas leakage from the enclosure. The apparatus includes an automated measuring subsystem for obtaining a physical parameter of the object which is then compared with data in a program controller's memory to determine a pass/fail leak rate for that particular object. The vacuum system used has separate vacuum lines to the enclosure and chamber and the test gas purging system combined with the use of separate vacuum lines results in the efficient and rapid purging of test gas prior to testing the next object.
