IPC: F02C7/22
Filed: 2005-01-18
Abstract: A method for preventing fuel from migrating, i.e., infiltrating, into a mircoporous polymer membrane, such as that used in a fuel deoxygenator devic e of an aircraft to remove dissolved oxygen from the fuel, includes heating the membrane to reduce the size of micropores in the membrane from a first size to a seco nd size that is large enough to allow migration of oxygen through the membrane and small enough to prevent migration of fuel into the membrane. The membrane is an amorphous fluoropolymer on a PVDF substrate and the micropores are reduced i n size by heating the membrane at a temperature between 130.degree.C and 150.degree.C for 2 hours.

Title: Walk aerator with inboard wheels
Inventor: GUST JACKIE R
IPC: A01B45/02
Filed: 2003-11-12
Abstract: A walk aerator comprises a frame (4) supported by a plurality of ground engaging wheels (18,20), the frame carrying a coring head (26) having a plurality of side-by-side tine assemblies (26). The wheels define a wheelbase which is substantially equal to or less than the width of a coring swath and the wheels are located in advance of the coring head to keep the wheels from passing over the holes or soil cores left in any preceding coring swathes formed by the aerator. The vertical position of the coring head is adjustable up and down as the ground contour changes to keep hole depth substantially constant. The tine assemblies are reciprocated by a single crankshaft (28) driven by a single pulley (90), the crankshaft being assembled from multiple crank arms that are splined and bolted together. Sealed bearings connect drive arms (34) that drive the tine assemblies to the crankshaft. The crankshaft can be disassembled to allow the sealed drive arm bearings to be replaced.  Integral core deflectors (140) are used on the drive arms. A connecting link (42) extending across each drive arm is used to connect each drive arm to the coring head to decrease the coring head depth.

Title: Improved method for reverse transcription
Inventor: HAYASHIZAKI YOSHIHIDE
IPC: C12N15/10
Filed: 1997-07-24
Abstract: A method for preparing a cDNA from a mRNA using a reverse transcriptase wherein reverse transcription is performed at a temperature at which the mRNA does not take a secondary structure, for example, at a temperature of 45°C or more. The method is performed, for example, using a heat-labile reverse transcriptase in the presence of a substance exhibiting chaperone function having chaperone function such as saccharides. The method is performed, for example, in the presence of metal ions necessary for activation of the reverse transcriptase and a chelating agent for the metal ions such as a deoxynucleotide triphosphate. The method is capable of reverse transcription over the full length of mRNA template even if the mRNA is a long chain mRNA and, as a result, producing a full length cDNA.

Patent CA-2518468-A1 (CA)
Title: Accounting method and logic for determining per-thread processor resource utilization in a simultaneous multi-threaded (smt) processor
Inventor: KALLA RONALD NICK
IPC: G06F11/34
Filed: 2004-04-14
Abstract: An accounting method and logic for determining per-thread processor resource utilization in a simultaneous multi-threaded (SMT) processor provides a mechanism for accounting for processor resource usage by programs and threads within programs. Relative resource use is determined by detecting instruction dispatches for multiple threads active within the processor, which may include idle threads that are still occupying processor resources. If instructions are dispatched for all threads or no threads, the processor cycle is accounted equally to all threads. Alternatively if no threads are in a dispatch state, the accounting may be made using a prior state, or in conformity with ratios of the threads' priority levels. If only one thread is dispatching, that thread is accounted the entire processor cycle. If multiple threads are dispatching, but less than all threads are dispatching (in processors supporting more than two threads), the processor cycle is billed evenly across the dispatching threads. Multiple dispatches may be detected for the threads and a fractional resource usage determined for each thread and the counters may be updated in accordance with their fractional usage.

Patent CA-2524018-A1 (CA)
Inventor: RICHMAN CHARLES I
IPC: B06B1/02
Filed: 2004-05-11
Abstract: Ultrasound for use in promoting a chemical reaction is generated by an electromagnet formed from a pair of magnetostrictive prongs wound with coils that are oriented to produce an oscillating magnetostrictive force when an oscillating voltage is applied, in conjunction with a sensing electromagnet of magnetostrictive material that is arranged to receive the vibrations generated by the driving electromagnet and produce internal magnetic field changes due to the reverse magnetostrictive effect. These field changes generate voltages that are representative of the amplitude of the oscillating magnetostrictive force. The generated voltage is compared to a target value in a control circuit that adjusts the applied oscillating voltage accordingly. The oscillations in the prongs of the electromagnet are transmitted to an ultrasonic horn that is immersed in the reaction medium to provide direct contact with the reaction mixture.
