Title: Method and device for closed-loop control of a steam turbine with a steam bleed
Inventor: JUNK RAINER
IPC: F01D17/02
Filed: 2000-03-24
Abstract: Method for closed-loop control of a steam turbine with a steam bleed, a closed-loop control device for a steam turbine with a steam bleed, and a steam turbine with a steam bleed The invention relates to a method for closed-loop control of a steam turbine (1) with a steam bleed (21, 23) for various operational tasks (BA, BB, BC), which are each characterized by the nature of the controlled variables (R1, R2) used for closed-loop control. Actuating signals (S1, S2, S3) for actuating elements (43, 45) for valves (15, 17, 19, 25, 27) are derived, using a closed-loop control structure (37), from closed-loop control signals (YE, YS) of the regulators (33, 35) which are used. Only a single closed-loop control structure (37) is used for all the operational tasks (BA, BB, BC), as a result of which the design of the closed-loop control is simplified, the closed-loop control signals (YE, YS) are decoupled, and a smooth changeover is achieved between the operational tasks (BA, BB, BC).

Patent CA-2369577-A1 (CA)
Inventor: SNAIDR JIRI
IPC: C12Q1/68
Filed: 2000-05-04
Abstract: The invention relates to a method for detecting microorganisms in a sample by means of a nucleic acid probe. Conventional detection methods are, for example, the in-situ hybridization of microorganisms with fluorescence-labeled oligonucleotide probes (fluorescent in-situ hybridization). A disadvantage of said method is that an epifluorescence microscope is required for evaluating the results. According to the invention, the disadvantages of the in-situ hybridization method are overcome by hybridizing the microorganisms to be detected in a sample with a specific nucleic acid probe, removing non-hybridized nucleic acid probe molecules, separating and then detecting and optionally quantifying the hybridized nucleic acid probe molecules.

Abstract: A dynamically tunable filter (10) controls the magnitude of couplings between core (16) and cladding (18) modes of a waveguide by surrounding the waveguide with an overcladding (20) having an adjustable refractive index. The coupled modes are attenuated along the core to produce the desired spectral response.  The adjustment to the overcladding (20) index is made in a range that is above the refractive index of the underlying cladding (18) to vary amplitudes of attenuated bands of wavelengths without shifting central wavelengths of the bands.

Abstract: A fluid delivery system for delivering and injecting fluid into heart tissue , or other organ tissues. The fluid delivery system includes an injection catheter disposed in an elongate sheath. A nozzle, including an injection array, is disposed adjacent the distal end of the injection catheter. In a first (microneedle) embodiment, the injection array comprises a plurality of  microneedles each defining an injection lumen in fluid communication with th e lumen of the catheter. In a second (needle-less) embodiment, the injection array comprises a plurality of injection lumens in fluid communication with the lumen of the catheter. Fluid is transferred to the injection lumen array  from a fluid source through the lumen in the catheter. The injection lumen array distributes the fluid at the injection site over a greater area than would otherwise be achieved with a single needle injection. Thus, the injection lumen array improves fluid retention in the tissue at the injectio n site.

Patent CA-2384729-A1 (CA)
Inventor: NORTON PETER R
IPC: C23C14/02
Filed: 2002-05-09
Abstract: Organic thin films are being exploited for a number of applications ranging from solar cells to organic light-emitting diodes (OLEDs). In such devices it is necessary to form a high quality electrical contact with the organic film of interest. The ability of a metal contact to stick to an organic film is often limited. This can be particularly problematic as evidenced by the deleterious formation of dark spots in OLEDs. We have shown that an organic film exposed to a plasma treatment demonstrates improved wettability, an enhanced sticking coefficient and better adhesion to a metal film thereafter deposited. It is further believed that this process leads to an improved electrical contact and suppression of dark spot formation. Thus, an increase in the lifetime of OLEDs and other electrical devices incorporating organic thin films is anticipated.

IPC: C07C51/353
Filed: 2000-11-17
Abstract: The present invention relates to metathesis syntheses for insect sex-attractant pheromones or their components, such as E-5-decenyl acetate, the major component of the Peach Twig Borer pheromone; (5R, 6S)-6-acetoxy-5-hexadecanolide, the mosquito oviposition attractant pheromone; E9, Z11-hexadecadienal, the pecan nut casebearer moth pheromone; 9-tetradecenyl formate, an analog of the Diamondback Moth (DBM) pheromone; 11-tetradecenyl acetate, the Omnivorous Leafroller (OLR) pheromone; E-4-tridecenyl acetate, the major component of the Tomato Pinworm (TPW) pheromone; E,E-8,10-dodecadienol, the Codling Moth (CM) pheromone. The syntheses preferably employ a Class I-IV metathesis catalyst, entail few reaction steps, use generally commercially available starting materials, and have relatively short process times. These syntheses produce good yields without the need for expensive or sophisticated equipment. The invention also provides an inexpensive route for producing omega-haloalkenols by cross-metathesizing alpha-omega-diacetoxy alkenes and alpha-omega-dihalides to yield omega-haloalkenols, which are easily converted into omega-haloalkanols under traditional hydrogenation methods.

Title: An online marketplace for moving and relocation services
Inventor: VENKATARAMAN SRINIVASAN
IPC: G06Q30/00
Filed: 2002-08-15
Abstract: Methods and systems for operating an online marketplace for the sale of services associated with self-help moving and relocating are described. A customer enters an online marketplace where service providers offer services relating to moving and relocating, specifically in the "do-it-yourself' moving field. The venue for the online marketplace is an Internet web site or a site on a computer network and is operated by a host that determines which service providers will be listed on the site. A  typical self-help moving customer may enter the marketplace after completing an initial transaction with the host, such as reserving a moving truck or trailer and other moving equipment. In many instances this transaction is what initially draws the customer to the site. Once in the marketplace, the customer can view informational content on numerous vendors providing services relating to moving and relocating. Based on the estimates provided by the marketplace, the customer selects the vendor and "purchases/prepays for "  his services on the marketplace. The funds are held in escrow until the transaction is fulfilled to the customer's satisfaction. The customer is provided a confirmation code.  The code is given to the service provider upon completion of the job. This is the key that unlocks the funds. The marketplace also does not release the funds unless and until all parties are satisfied with the transaction. The customer selects the vendor that best suits the needs and budget of the customer by viewing rates, reviews, ratings, customer feedback, and background information on the vendor. In this manner control over the transaction lies more with the customer than with the vendor
