Patent AU-3736999-A (AU)
Title: Process for selective oxidation of primary alcohols
Inventor: LUGT JAN PIETER VAN DER
IPC: C07C45/29
Filed: 1999-05-04
Abstract: Primary alcohols, especially in carbohydrates, can be selectively oxidized to aldehydes and carboxylic acids in a low-halogen process by using a peracid in the presence of a catalytic amount of a di-tertiary-alkyl nitroxyl (TEMPO) and a catalytic amount of halide. The halide is preferably bromide and the process can be carried out at nearly neutral to moderately alkaline pH (5-11). The peracid can be produced or regenerated by means of hydrogen peroxide or oxygen. The process is advantageous for producing uronic acids and for introducing aldehyde groups which are suitable for crosslinking and derivatization.

Inventor: CAMPAU DANIEL N
IPC: E03D9/02
Filed: 1993-05-10
Abstract: An apparatus (10) and method are disclosed for dispensing a first liquid (26) into a second reservoir liquid (30). The apparatus comprises a container (12) adapted to hold the dispensable liquid, a dispensing nozzle (14) and a sensing tube (18). The dispensing nozzle is positioned on the container below the dispensable liquid level (28) within the container.

Title: Method for manufacturing a multilayer printed circuit board and composite foil for use therein
Inventor: GALES RAYMOND
IPC: H05K3/02
Filed: 2000-03-23
Abstract: A method for manufacturing a multilayer printed circuit board includes providing a core board, a composite foil including a carrier foil, a functional copper foil and a non-reinforced thermosetting resin layer, the functional copper foil being electro-deposited with a uniform thickness of more than 4 mum but less than 10 mum on the carrier foil, the functional copper foil having a front side facing the carrier foil and an opposite backside which is coated with the non-reinforced thermosetting resin layer. The method further involves laminating the composite foil with the non-reinforced thermosetting resin layer on the core board and removing the carrier foil from the functional copper foil in order to uncover the front side of the functional copper foil. A CO2 laser source drills holes from the uncovered front side of the functional copper foil through the functional copper foil and the non-reinforced thermosetting resin layer to form microvias.
Patent AU-4110800-A (AU)
Title: Quenching apparatus
Inventor: GARCIA RAUL JASSO SR
IPC: F28C3/06
Filed: 2000-03-23
Abstract: A quench nozzle design introduces quench oil tangentially into the quench tube which cools the hot gaseous pyrolysis products coming out of the hot radiant tubes in a pyrolysis furnace (in ethylene manufacture). Besides cooling the hot gases, the quench oil introduced into the quench tube by this nozzle design keeps the wall of the quench tube wetted, which is necessary to prevent coke deposition on the quench tube. The nozzle has one quench oil entry, which eliminates the need for any restriction orifice required to evenly distribute quench oil flows that would otherwise be required with several nozzle entries. Also, the one-nozzle oil introduction has a larger diameter than that required where more than one nozzle is employed in this service. The replacement of multiple nozzles with a single larger diameter nozzle eliminates plugging problems caused by coke solids or, coke solid precursors, present in the quench oil.

Patent AU-5024400-A (AU)
Title: Display stand
Inventor: POMPER YAEL SONIA
IPC: A47F7/00
Filed: 2000-05-17
Abstract: A jewelry display stand including a vertical post assembly mounted on a base. A plurality of arms, serving as hanger elements for jewelry or other merchandise, radiate from the post. The arms co-operate with anti-removal elements on the post that prevent merchandise from being removed from the spokes. In one embodiment a ring engaging the tips of the arms provides the anti-removal elements. In another embodiment the anti-removal elements are a set of spokes above the arms. Either the arms or the spokes are movable up and down and are spring-biased upwards, to a position in which the arms are separated from the anti-removal elements and merchandise can be removed from or placed on the arms. A cap on the post engages the movable elements, holding them down, and keeping the arms engaged with the ring or spokes. A slot in the cap allows one arm or spoke to rise to the non-engaging position, and the cap is rotatable about a vertical axis so that the slot can be aligned with any selected arm or spoke. Thus, merchandise can be removed from only the selected arm, reducing the risk of pilferage.

Title: Symmetry based subband acoustic echo cancellation
Inventor: EHRENSTRALE FREDRIK
IPC: H04M9/08
Filed: 2000-05-29
Abstract: Processing complexity in an acoustic echo canceller can be reduced by partitioning the input near-end and far-end signals into respective pluralities of frequency subband signals. Also, due to the complex conjugate symmetry of conventional Discrete Fourier Transform matrices, not all of the subband signals of each plurality need be subjected to echo cancellation processing. The subband signals that would have otherwise been produced by echo cancellation processing are instead provided by producing complex conjugates of selected ones of the subband signals that have been subjected to echo cancellation processing.

Title: Production of copper compounds
IPC: C01G3/06
Filed: 1990-06-29
Abstract: A method of producing copper compounds involves contacting metallic copper with oxygen or an oxygen-containing gas, with an aqueous solution consisting essentially of water in solution in which is a soluble ammonium salt NH4X, where X is the anion of the salt, and with ammonia in an amount such that the solution is initially alkaline. As a result of such contact the metallic copper is initially dissolved to form a copper ammine Cu(NH3)4X and the formation of the ammine continues until the saturation concentration of the ammine is reached. Subsequently, the ammine continuously breaks down to form 3Cu(OH)2.CuX2 and the water soluble products of the ammine decomposition continuously reform the amine by further reaction with the metallic copper and the oxygen on oxygen-containing gas.
