    摘要： A speaker enclosure and method of building same is provided for redirecting standing waves outside the enclosure. The enclosure includes an exterior and an interior comprised of a body having six interior surfaces defining the interior. One of the surfaces has a speaker opening and another of the surfaces has a tuned port opening and defines four corners opposite the speaker opening. An element having an acoustically reflective surface faces the interior and is positioned in a plane that intersects and is inclined with respect to each of the interior surfaces that form the corner. A handle system that includes an attachment means is mounted to the exterior of the enclosure. A rotatable and detachable handle is mounted to the attachment means.

    摘要： A protective sleeve disposed around a cable and a connector which are connected includes a cable sleeve and a plurality of resilient elements. The cable sleeve includes a bushing, a first ring, and a second ring. The front of the bushing is connected to the connector. The first ring and the second ring are disposed around the cable. The resilient elements are formed by extending the second ring and spaced apart from each other to form an opening for penetration by the cable. The caliber of the opening is less than the caliber of the second ring. Accordingly, the resilient elements are conducive to the positioning of the cable while the cable is penetrating the rings.

    摘要： This invention relates to the simultaneous treatment of the internal and external surfaces of turbine blades or vanes. In particular it provides a process for coating an external and an internal surface of a turbine blade or vane with aluminium and chromium, respectively, at substantially the same time. The process comprises the following steps (i) and (ii) in either order: (i) applying to the external surface an aluminising compound comprising aluminium, a moderator, an energiser and a diluent; and (ii) applying to the internal surface a chromising compound comprising chromium, an energiser and a diluent. These steps are followed by (iii) heating the turbine blade or vane to form an aluminium layer on the external surface and a chromium layer on the internal surface. The invention also provides a suitable aluminising compound and a chromising compound per se.
