Abstract: An ultrasonic systems and methods for sealing complex interfaces or for metal forming. Complex interfaces, such as a Gable top, have multiple and a variety of layers across the interface, or an oval or round spout having a complex geometry. An example system includes two ultrasonic horns arranged opposite a gap between which the interface is provided. The frequency and phase of the ultrasonic energy are synchronized as the energy is applied simultaneously while the interface is pressed between a jaw and the energy is applied to both sides of the interface. Another example system includes two ultrasonic transducers synchronized in frequency and phase and used to vibrate a horn mechanically to facilitate a sealing or welding interface or to assist in a metal-forming process.

Abstract: An ultrasonic system and method for sealing a complex interface, such as a Gable top, having multiple and a variety of layers across the interface, or an oval or round spout having a complex geometry. The system includes two ultrasonic horns arranged opposite a gap between which the interface is provided. The frequency and phase of the ultrasonic energy are synchronized as the energy is applied simultaneously while the interface is pressed between a jaw and the energy is applied to both sides of the interface. Only one application of the frequency- and phase-synchronized ultrasonic energy is required to hermetically seal all the layers of the interface together.

Abstract: A system and process is disclosed for binding particles to a carrier material in an isolated relationship for use in composite fabrication. A slurry comprising particles dispersed in fluid is created in particle suspension tanks, deposited as a uniform layer and filtered using reduced pressure applied to a filter belt to leave behind isolated particles, the reduced pressure further acting to overcome electrostatic and other forces of attraction between the particles until they can be permanently bound to the carrier with a binder or adhesive and collected on a take-up roll.

Abstract: A device for securing a headwear to a carrying bag utilizing a first holder attachable to the carrying bag and configured to secure the shading member of a headwear, and a second holder attachable to the carrying bag configured to secure the securing member of the headwear.

Abstract: An apparatus for testing a cleaning procedure for a material. The apparatus includes a rack having a seat configured to retain a plurality of test coupons at a predetermined angle, an upper tray that distributes a solution along the lines of the rack, a lower tray for receiving solution passed over coupons disposed on the rack, a meter that gauges a flow rate of the solution, a thermostatic heater adapted to bring the solution to a predetermined temperature, and a variable speed pump that directs the solution from a reservoir to the upper tray.

Abstract: A process for protecting an article using an anti-icing coating includes the steps of applying upon at least one surface of an article an anti-icing composition comprising at least one polysiloxane free of additives; and curing the anti-icing composition to form an anti-icing coating exhibiting an ice shear strength of about 19 kPA to about 50 kPa.

Abstract: The invention comprises an abradable material containing about 1.5 to about 5 weight percent of an abradable organic microballoon filler within an abradable silicone polymer matrix.

Abstract: Liquid and/or solid anti-icing fillers and/or oils are combined with erosion resistant silicone and/or fluorocarbon elastomeric materials to create erosion resistant anti-icing coatings. These coatings may be utilized to prevent ice build-up on various gas turbine engine components, aircraft components, watercrafts (i.e., boats and ships), power lines, telecommunication lines, etc.

Abstract: This invention relates to a method of seepage control which comprises contacting a soil surface with a composition comprising anionic copolymers and a surfactant. This invention provides a method of seepage control for irrigation ditches, drainage ditches, farm ponds, feeder canals, golf course water features, park ponds and lakes, lagoons, and the like.

Abstract: A headwear item such as a cap, having a mutiaxially stretchable band is provided. The band comprises multiple layers of uniaxially or multiaxially stretchable material connected with elastic stitching for making the band multiaxially stretchable. Such biaxially stretchable band may utilize any fabric that is uniaxially or biaxially stretchable for the layers of the band, allowing for a wide variety of fabrics to be utilized. Additionally, the elastic stitching between the layers of the band provide for varying space between the layers, making the band lighter, and providing comfort and breathability to the wearer.

Abstract: A household trash delivery system having a guidance member moveable within a track. The cart is controlled by a programmable timer to send the cart from a household location to a curbside destination at a desired time, and the return of the cart from the curbside destination to the household destination at a second desired time. The cart may be elevated above obstacles adjacent to the track such as a mound of snow and has a built in pressure sensitive system to cut off power temporarily if it encounters an obstacle such as a small child within the path of the cart.
