Patent CA-2390243-A1 (CA)
Inventor: ELDRIDGE RICHARD ALLEN
IPC: H02M3/155
Filed: 2002-06-11
Abstract: The present invention provides a modified buck regulator circuit capable of providing two output voltage levels. The circuit includes an inductive element connected between the input and output of the circuit. Further, the circuit includes an auto-transformer and two switches creating separate current paths with a load connected to the output of the circuit. In one mode, the switches are operated in parallel to provide a first voltage across the load. Because the switches are in parallel with respect to each other, the load current is divided between the two switches. In a second mode, the switches are operated in a push-pull mode. In this mode, the auto-transformer steps down the load voltage and also effectively steps down the current across each switch. As such, the buck regulator circuit of the present invention may provide two separate voltages, while also reducing the current across the switches of the buck regulator circuit.

Title: Combined oil return and compressor discharge temperature limitation regarding flooded economizer heat exchanger
Inventor: FREUND PETER W
IPC: F25B43/00
Filed: 1995-01-13
Abstract: A refrigeration system of the type having an economizer cycle is provided with a null cycle, in addition to heating and cooling cycles, without shutting a compres-sor prime mover down, to preserve air flow in a conditioned space. First, second and third controllable valves respec-tively: (1) select main and auxiliary condensers, (2) open and close a liquid line, and (3) open and close a line which provides a warm liquid to an economizer heat exchang-er. The valves are controlled in at least one predeter-mined open/close pattern during a null cycle, and prefera-bly in a plurality of selectable predetermined open/close patterns, to provide a null cycle at any instant which sub-stantially matches the net heat gain or loss taking place in the conditioned space. Thus, the temperature of the served space will be more apt to remain in a null tempera-ture range close to set point, providing smoother and more accurate control over the temperature of the conditioned space for longer shelf life of perishables stared therein.      The system achieves the latter by controlling cooling circulation in the compressor oil cooler.

Filed: 2000-12-21
Abstract: This invention relates to the use of a supplemental promoter in conjunction with a noble-metal-containing catalyst comprising a carbon support in catalyzing liquid phase oxidation reactions, a process for making of an improved catalyst comprising such a supplemental promoter, and an improved catalyst comprising such a supplemental promoter. In a particularly preferred embodiment, a supplemental promoter (most preferably bismuth or tellurium) is used in conjunction with a noble-metal-containing catalyst comprising a carbon support in a liquid phase oxidation process wherein N-(phosphonomethyl)iminodiacetic acid (i.e., "PMIDA") or a salt thereof is oxidized to form N-(phosphonomethyl)glycine (i.e., "glyphosate") or a salt thereof. The benefits of such a process include increased oxidation of the formaldehyde and formic acid by-products, and, consequently, decreased final concentrations of those by-products as well as other undesirable by-products, most notably N-methyl-N-(phosphonomethyl)glycine (i.e., "NMG").

IPC: H01L23/532
Filed: 2001-12-20
Abstract: A method of forming a microelectronic device while preventing photoresist poisoning. Various layers of conductive metals and dielectric materials are deposited onto a substrate in selective sequence to form an integrated circuit. Vias and trenches are formed throughout the structure by exposing and patterning a photoresist material. The dielectric materials of the insulating layers are protected from the photoresist to prevent chemical reactions which lead to photoresist poisoning. This is done by forming a modified surface layer on the dielectric material by either depositing an additional layer that covers the dielectric material, or by modifying the exposed surface of the dielectric material to a plasma or chemical treatment.
