Patent AU-2407300-A (AU)
Title: Speaker system
Inventor: PORZILLI MARK G
IPC: H04R1/40
Filed: 2000-01-06
Abstract: A speaker system comprises a housing that includes a front wall with a plurality of openings, and first and second exterior sidewalls. A plurality of vertically arranged speakers are each placed into an associated one of the plurality of openings and secured to the housing. A hemispherical concave interior wall is positioned in back of the plurality of speakers and within said first and second sidewalls to disperse and attenuate audio waves within the housing. The housing may also include a tuned, dampening bisector that is mounted to the hemispherical concave interior wall positioned in back of said plurality of speakers and within the first and second sidewalls. The bisector is preferably located at the center of the hemispherical concave interior wall. A rear exterior wall defines a back of the speaker system and the front wall defines a front of the speaker system. The first and second interior sidewalls extend from front to back and preferably taper inward from back to front of the speaker system, wherein the first and second interior sidewalls each mate with the hemispherical concave interior wall. The plurality of speakers preferably include mid-range drivers and tweeters. For example there may be two tweeters associated with every mid-range driver. In one embodiment there are for example twenty-one mid-range driver and forty-two tweeters, wherein two tweeter openings are adjacent to an associated one of the mid-range openings. The speakers are arranged electrically in a series/parallel configuration. For example, several mid-range speakers/drivers are arranged in a series configuration to provide a mid-range subarray, and the number of mid-range drivers placed into each sub-array is selected such that the total Q factor for the sub-array is approximately one.

Title: Modular prosthetic joint and extraction tools
Inventor: ZILE RICHARD R VAN
IPC: A61F2/38
Filed: 1989-01-09
Abstract: A tool for removal of a joint prosthesis intended for implantation in a body. The prosthesis includes a component adapted to be fixed to a long bone having an intramedullary canal and further includes an elongated male stem having a uniformly tapered outer surface. In order to accommodate the particular size of long bone to which the component is to be fixed, a properly sized female stem is attached to the male stem before the component is fixed to the long bone. The female stem is adapted to be received in the intramedullary canal for fixation thereto, and has a uniformly tapered inner surface, the angle of the taper being substantially similar to the angle of taper of the outer surface of the male stem. As a result, the male stem and female stem become locked together when the inner surface of the female stem engages the outer surface of the male stem. The tool serves to disengage is obtained the male stem from the female stem as well as to disengage the female stem from the bone.

Title: Process suitable for the production of beer having a low alcohol content
Inventor: SCHUR FRITZ DR
IPC: C12G3/08
Filed: 1989-08-08
Abstract: A process for the production of beer with a low alcohol content is described. The process comprises preparing a wort by boiling and adding ascorbic acid to such wort prior, during, or after boiling, so long as the wort remains hot. The process can be employed according to the invention for the production of non-alcoholic beer by the yeast cold contact process, in which yeast recovered from a fermentation process is brought into contact with the wort at a low temperature below 0 DEG  C. As a rule, the non-alcoholic beer produced by this process imparts an unpleasant and bitter aftertaste. By adding ascorbic acid to the boiling wort, the bitter aftertaste is completely eliminated.
