Title: Temperature-controlled microchip laser assembly and associated submount assembly
Inventor: PETERSON BRIAN L
IPC: H01S5/022
Filed: 1999-11-01
Abstract: A microchip laser assembly provides a microchip laser along with an integral Peltier thermoelectric temperature controller and temperature sensor. The temperature sensor measures the temperature of the microchip laser during operation so that the polarity and magnitude of a direct current to Peltier thermoelectric elements may be controlled, thereby controlling the temperature of the microchip laser and stabilizing the optical output frequency or other microchip laser operating parameters. The microchip laser assembly can be mounted, along with a pump source, upon a submount such that the microchip laser can be optically pumped. As a result of the construction of the microchip laser assembly, the temperature of the microchip laser can be controlled independent of the temperature of the pump source.

Title: Pneumatic vehicle suspension system with variable spring stiffness
Inventor: PENZOTTI ROGER P
IPC: B60G17/052
Filed: 2000-01-12
Abstract: A pneumatic suspension system for a vehicle providing minimum pneumatic spring stiffness to minimize frame beaming in the vehicle' frame. In one embodiment of the invention, the pneumatic suspension system has a first pneumatic spring connected to a first axle and to the frame. A second pneumatic spring is connected to the second axle and to the frame. The first and second pneumatic springs contain pneumatic fluid. A conduit containing pneumatic fluid is in fluid communication with the first and second pneumatic springs. The conduit allows the fluid to move between the first and second pneumatic springs. The pneumatic fluid in the conduit has a fluid resonant frequency. The first and second pneumatic springs and the conduit define a system having a variable stiffness dependent upon an input vibration frequency. The input vibration frequency is a predetermined fraction of the fluid resonant frequency. The pneumatic conduit is sized so the predetermined fraction of the fluid resonant frequency corresponds to the frame beaming frequency, thereby providing minimum stiffness of the system at the frame beaming frequency.

Patent CA-2302193-A1 (CA)
Inventor: GHANDOUR GHASSAN
IPC: C12Q1/68
Filed: 1998-09-08
Abstract: Systems and methods for identifying, confirming, mapping, and categorizing sample polymers, such as nucleic acid sequences, are provided. An estimation of the fraction of first and second polymers in a sample of polymers can be calculated by inputting a first hybridization value indicative of hybridization affinity of the sample of polymers to polymers probes that are complementary to the first polymer and inputting a second hybridization value indicative of hybridization affinity of the sample of polymers to polymers probes that are complementary to the second polymer. The estimation of the fraction of the first and second polymers in the sample of polymers can then be calculated by dividing the first hybridization value by a sum of the first and second hybridization values. Estimations of the fractions of alleles in a sample can be clustered to form a fraction pattern usable for identifying, confirming, mapping, and genotyping sample nucleic acids.

Title: Control processor switchover for a telecommunications switch
Inventor: BARACKA RONALD LOUIS JR
IPC: H04Q3/545
Filed: 1998-08-25
Abstract: First and second control processor cards (12, 14) are employed in conjunction with first and second switch fabric cards (16, 18) to interconnect Input/Output cards (24) in a telecommunications switch (10). The control processor cards (12, 14) provide a portion of the functionality previously associated with switch fabric cards (16, 18), such as exertion of control over allocation of bandwidth within the switch. The control processor cards also provide new functionality. In particular, each control processor card can configure both switch fabric cards (16, 18). Redundant control processor cards and redundant switch fabric cards are employed to provide a switch that is less susceptible to failure than switches with only redundant switch fabric cards. Hence, failure of a control processor card and a switch fabric card can be sustained without resulting in switch failure. Timing control functions may also be provided by a separate timing module card (20, 22).

Title: Thermo-acoustic insulation system for sanitary device
Inventor: PIMPARE BRUNO
IPC: A47K3/16
Filed: 2000-03-31
Abstract: The whirlpool tub includes a rigid tub shell inserted into the opening of a surrounding podium. The tub is to be filled with hot water. A first insulation membrane is installed spacedly around the tub inside the podium, defining a first closed air pocket between the tub and this first insulation membrane. A second insulation membrane is installed spacedly around the first insulation membrane, also inside the podium, defining a second closed air pocket between the first and the second membranes. The first membrane is punctured and hangs loosely from the podium structure, thus allowing limited air circulation between the first and second air pockets. Consequently, positive condensation control is accomplished, preventing same from occurring, in addition to providing thermal and acoustic insulation to the tub. The first membrane comprises an inner reflective metallic foil fixedly mounted on a synthetic felt backing. The second membrane is a mineral wool blanket.

Title: A method for recovering the valuable metal content of a sulphuric acid leaching solution
Inventor: SUNDKVIST JAN-ERIC
IPC: C22B3/18
Filed: 2000-05-24
Abstract: A method for winning the valuable metal content of a leaching solution acidified with sulphuric acid, by solvent extraction and electrowinning and a following final product winning stage, for instance an electrowinning stage, wherein the pH of the leaching solution is raised successively to precipitate out the iron and arsenic present in a first precipitation stage, removing said first precipitate, and precipitating the valuable metal content of the leaching solution substantially totally in a following precipitation stage. The resultant precipitate containing valuable metal and gypsum is removed and leached in an acid environment to re-dissolve the valuable metal content, and the thus formed acid solution and its metal content are delivered to a solvent extraction circuit in which the metal content is converted to a substantial degree to an acid electrolyte from which metal or some other end product is won. The acid solution deplete of valuable metal and deriving from the solvent extraction stage can be returned to the stage in which the valuable metal content is re-dissolved and, when electrowinning is used for winning the end product, electrolyte deplete of valuable metal can be cycled from the electrowinning stage to the solvent extraction circuit.
