Abstract: Floor coverings having a greige good, an adhesive layer, and a secondary backing material. The greige good has a primary backing component having adjoined first and second portions, and a plurality of fibers. The secondary backing material has an attached portion and a first exposable portion, with the attached portion adhered to the first portion of the primary backing component by contact with the adhesive layer. The second portion of the primary backing component is unattached to the first exposable portion of the secondary backing material, and the first exposable portion defines a portion of the first end edge of the floor covering. The second portion of the primary backing component is selectively moveable relative to the first portion to a position in which at least a portion of the second portion of the primary backing component does not overlie the first exposable portion of the secondary backing material.

Abstract: A method of at least partially removing an oxide layer from the surface of an aluminium work piece or product. The method comprises introducing the work piece or product into a processing chamber and exposing the work piece or product to a solid particulate cleaning material. This material comprises a multiplicity of particles.

Abstract: The tool includes a rigid base with an upright rigid post attached perpendicularly to the base a rigid form fitted outer sleeve, measured to fit snug over the upright post. This sleeve allows for height adjustability, also includes a uniquely formed and rigid wand, with a measured, weighted counterbalance end with a small hole to accommodate a bungee cord attachment and on the other end a set and re-settable fix tennis ball mounting the tennis ball itself is mounted on a spindle on a small rod which allows free rotation of the ball for the purpose of ball striking muscle memory development, the ball-mounting wand is bent, geniculate and curved into a question mark like configuration using holes and peg attach the wand to the crown of the form fitted outer sleeve using the counterbalance and the bungee cord the ball can be repeatedly struck, displaced and self-reset.

Abstract: A device comprising a solid-state actuator (100), means for inputting an acoustic signal to the actuator (104) and means for measuring the resultant signal (104). The measured acoustic signal can be used to determine the extension of the solid-state actuator.

Abstract: A package of oxygen sensitive product (10) has a body (5) a lid (15). The lid (15) includes a membrane (17), which incorporates ink (16), adapted to react to the presence or absence of a particular gas or mixture of gases in the headspace (25) of the package. The ink (16) is protected from the external environment by a barrier material (50, 51, 52), but is in fluid communication with the headspace (25). The barrier material (50, 51, 52) is chosen such that a user of the package may detect the reaction of the ink (16) through the barrier material.

Abstract: A transducer for transmitting and receiving ultrasound waves and a method for constructing a transducer. The transducer having layers of a single crystal piezoelectric material stacked in a multilayer arrangement and a polymer material geometrically arranged within each layer to form a 3-1 connectivity piezoelectric and polymer composite. The multilayer arrangement includes at least two layers of different thickness. The structure allows the generation of odd and even harmonics to significantly increase bandwith without reducing signal amplitude or efficiency.

Abstract: The invention relates to a thin film aluminium nitride ultrasound transducer, a method of manufacture the transducer and a test component upon which a thin film aluminium nitride ultrasound transducer is deposited. The aluminium nitride film may be (002) orientated with its c-axis normal to the surface of a substrate made of glass or a composite material. The invention also includes a system for non-destructive testing wherein a pulse is emitted from an ultrasound transducer to propagate through the test component and a reflected pulse is detected by the aluminium nitride thin film ultrasound transducer. The ultrasound transducer can be integrated into engine components such as bearings.

Abstract: An ultrasound waveguide that is attachable to an ultrasound probe so as to identify a target area on a target object. The ultrasound waveguide has an ultrasound transducer coupling signal to be transmitted through a guide means. The ultrasound waveguide also has a positioning means for positioning the guide means in relation to the target area on the target object. The guide means is provided with a channel that provides a discontinuity within the guide means that causes a discontinuity in the ultrasound signal emitted by the probe. The presence of this discontinuity allow for proper alignment of the ultrasound waveguide with the target object.

Abstract: The present invention provides a wall for a package, which wall comprises, or includes a layer comprising, a composition comprising a polymer and capable of scavenging oxygen through the metal-catalysed oxidation of an oxidizable organic component thereof. The oxidizable organic component is preferably itself a polymer, and may be the only polymer in the composition. Preferred compositions include a blend of 96% polyethylene terephthalate and 4% poly (m-xylyleneadipamide) containing 200 ppm cobalt as catalyst, with good permeance-versus-time performance (3) when formed into a bottle.
