Patent number: 7498502Abstract: A keyboard musical instrument comprises a keyboard having a plurality of playing keys, a fallboard pivotably supported at its rear end for covering the keyboard when the instrument is not in use and exposing the keyboard when the instrument is in use, and a rear top board. An accommodation space is provided between the keyboard and the rear top board and is adapted for receiving the fallboard which turns through 180 degrees to wide open the space from above the keyboard through above the rear top board. Thus, while the instrument is in use, the fallboard will obstruct neither the player's view nor the sound propagation from the loudspeakers, and further the fallboard will help in supporting the music sheets.Type: GrantFiled: December 26, 2006Date of Patent: March 3, 2009Assignee: Yamaha CorporationInventors: Daisuke Saito, David Keech

Publication number: 20050088031Abstract: A tail extension (1) adpated to be pivotally attached (2) to a load carrying container (3). Tail (1) pivots between a first position substantially outwards from a floor of the container, and a second position upwardly inclined realtive to said floor. Tail (1) may be formed as one or a plurality of sections which move individually or cooperatively. Tail (1) may be pivotally connected (2) adjacent the floor of container (3) by a hinge allowing free movement and/or may be displaced by a drive means (e.g. hydraulic, mechanical, pneumatic). By tail (1) being able to pivot when contracting the ground, tail (1) and container (3) are not going to be subjected to undue forces which may damage tail (1) or container (3). When being transported, tail (1) acts as an extension to improve the load carrying capacity of the container by extending outwardly, or, can be displaced upwardly by a drive means to form a rear wall on the container.Type: ApplicationFiled: May 24, 2004Publication date: April 28, 2005Applicant: Keech Castings Australia Pty LimitedInventors: David Keech, Alexander Hand

Patent number: 4468962Abstract: An energy loss detecting apparatus for measuring the rate of flow of the vapor phase of a bi-phase fluid flow, in the presence of an unknown quantity of the liquid phase, by separating the vapor phase from the liquid phase and producing a signal representing the vapor phase flow rate. The apparatus includes a hollow separator casing provided with a tube communicating with at least one of the inlet opening and outlet opening of the casing and facing thereinto. A wall seals the interior of the tube from the interior of the casing except at reduced diameter holes in the wall, the diameter of the holes being less than the inside diameter of the tubes at the wall. Energy loss due to a faulty steam trap is measurable by interposing the vapor flow rate measuring apparatus in a steam line between a steam consuming device and the steam trap.Type: GrantFiled: March 5, 1982Date of Patent: September 4, 1984Assignee: Armstrong International, Inc.Inventors: David A. Keech, Robert T. Kirchner, Nicholas M. Vander Wal, John E. Sorenson, Mark D. Driscoll

Patent number: 4456173Abstract: An energy loss detection system includes an apparatus (22) for measuring loss of the vapor phase of a bi-phase fluid. Such apparatus is interposable in an energy transfer circuit downstream of an energy consumer device (14), intended to take energy from the bi-phase fluid by converting the vapor phase to liquid, and upstream of a potential energy loss device (20). The apparatus includes a separator (24) for separating the vapor and liquid phases of the bi-phase fluid into separate flow paths. A probe (51) senses the flow rate of the vapor phase through the separator and produces a signal related thereto. An output apparatus (72) includes a readout device (79) responsive to the probe signal for producing a display indicative of vapor flow rate and hence of energy loss downstream of the separator.Type: GrantFiled: September 2, 1981Date of Patent: June 26, 1984Assignee: Armstrong International, Inc.Inventors: David W. Miner, Mark D. Driscoll, John E. Sorenson, Robert T. Kirchner, David A. Keech

Patent number: 4149557Abstract: An inverted bucket-type steam trap has a completely sealed casing of uniform wall thickness and preferably made of stainless steel. The casing is comprised of an upper part and a lower part. The lower part and the upper part both have a cylindrical wall portion which is open at one end and closed at the other end by a spherical segment-shaped bottom wall. The upper part and the lower part are affixed to each other by welding. The upper part has sidewardly extending outlet and inlet fitting means welded thereto. A valve is provided in association with the outlet fitting means. An inverted bucket is movable vertically inside the casing in response to the presence of condensate therein to operate the valve between opened and closed positions. An inlet tube is provided inside the casing and it extends from the inlet fitting means into the lower end of the bucket.Type: GrantFiled: September 6, 1977Date of Patent: April 17, 1979Assignee: Armstrong Machine WorksInventors: David A. Keech, Ronald D. Schlesch, Robert F. Lyons
