Abstract: A construction beam (100, 100a-c, 200, 300) includes a pair of lateral members (102, 102a-c, 202, 302, 104, 104a-c, 204, 304) and a resilient web (106, 106', 106'', 106''', 206, 306a-b) extending therebetween, so as to present a cross-sectional profile corresponding to commonly used construction beam members (for example, 2"  × 4" or 2" × 6''). The resilience of the web (106, 106', 106'', 106''', 206, 306a-b) helps to attenuate sound transmission through the beam (100, 100a-c, 200, 300) from one lateral member (102, 102a-c, 202, 302, 104, 104a-c, 204, 304) to the other. Ends of the resilient web (106, 106', 106'', 106''', 206, 306a-b) are fixed to respective ones of the lateral members (102, 102a-c, 202, 302, 104, 104a-c, 204, 304) on opposite sides of an imaginary reference plain (108, 208) passing through both of the lateral members (102, 102a-c, 202, 302, 104, 104a-c, 204, 304). In particular, in a wall frame, the lateral members (102, 102a-c, 202, 302, 104, 104a-c, 204, 304) are mounted at opposite ends thereof to end plates consisting of other construction beams (100, 100a-c, 200, 300) according to the present invention (that is, a pair of lateral members (102, 102a-c, 202, 302, 104, 104a-c, 204, 304) with a resilient web (106, 106', 106'', 106''', 206, 306a-b) extending therebetween). When used in a frame of a building structure, the lateral members (102, 102a-c, 202, 302, 104, 104a-c, 204, 304) of the end plates on the same side are attached to the surrounding structure, leaving the other side of the frame resiliently free floating. A wall is mounted on the free floating side of the wall frame so as to provide a resiliently free floating wall that acts as a sound attenuating "diaphragmatic" absorber.

Title: Sulfur storage method and system
Inventor: PICKREN ROY ANTHONY
IPC: E21C41/20
Filed: 2002-04-09
Abstract: A method and a system are provided for the safe storage and long-term conservation of commercially produced sulfur. An underground cavity is identified and selected from a naturally occurring earth formation such that its permeability and porosity allow sulfur to be retained within the underground cavity. A borehole that penetrates the cavity from the surface of the earth through the formation is provided, and the sulfur, in either liquid or solid form, is injected through the borehole, which is preferably lined with a substantially impervious liner such as a metal pipe. When feeding liquid sulfur to the system, a set or concentric pipes is placed within the borehole to circulate pressurized hot water (at 280° - 320° F) or other heating fluid through an annular space within the concentric pipes so as to impart enough heat within the borehole to maintain the sulfur being injected in liquid state while inside the borehole. The method and the system are particularly suited for the long-term storage of both mined and recovered sulfur. Solution-mined, salt--enclosed cavities, located at less than about 3,000 feet of depth are preferred. The stored sulfur is withdrawn, when desired, by injecting pressurized hot water (at 280° - 320°F) through a first annular space, created within the same borehole, and pressurized air through a second annular space, also created within the borehole, so as to cause the sulfur within the cavity to melt and rise to the surface of the earth through a centric space within the borehole. The stored sulfur may also be withdrawn through a separate borehole that penetrates the underground cavity at a different location and is equipped with similar means for delivering a heating fluid and air to the cavity and cause the sulfur to melt and come up to the surface in liquid state.

Title: Acoustic correction apparatus
Inventor: OLIVER RICHARD
IPC: H04R5/033
Filed: 2000-10-04
Abstract: An acoustic correction apparatus (120) processes a pair of left and right input signals (126, 128) to compensate for spatial distortion as a function of frequency when said input signals (126, 128) are reproduced through loudspeakers (246, 247) in a sound system. The sound-energy of the left and right input signals (126, 128) is separated and corrected in a first low- frequency range and a second high-frequency range. The resultant signals are  recombined to create image-corrected audio signals (130, 132) having a desir ed sound-pressure response when reproduced by the loudspeakers (246, 247) in th e sound system. The desired sound-pressure response creates an apparent sound image location with respect to a listener (250). The image-corrected signals  (130, 132) can also be spatially-enhanced to broaden the apparent sound imag e and improve the low frequency characteristics of the sound when played on small loudspeakers.
