Title: Method for transfer of molecular substances with prokaryotic nucleic acid-binding proteins
Inventor: BOHM GERALD
IPC: C12N15/87
Filed: 2000-11-03
Abstract: The invention relates to a method for the transfer of molecular substances, for example proteins or nucleic acids in cells, in the case of using DNA combined with a possible gene expression. A prokaryotic nucleic acid-binding protein is used for the transfer, which is preferably obtained from a thermostable organism. Where the substance to be transferred is a nucleic acid, the protein forms a reversible complex with the nucleic acid. The prokaryotic protein condenses and compacts the nucleic acids. Said nucleic acids can be taken up in the target cells after suitable incubation.

Title: Valve stem seal assembly with locator system
Inventor: LEHMANN ROBERT W
IPC: F01L3/08
Filed: 2002-07-25
Abstract: A valve stem seal component overcomes potential orientation misplacement, particularly in cases where no valve stem seal is to be used on an adjacent valve.

A plurality of such seal components are employed per engine, each component designed for insertion over at least the intake valve guide of each cylinder. Each component includes a valve stem seal module adapted to be installed over the intake valve guide. A locator is attached to the module via a radial connection portion that extends between the module and locator. The radial connection portion includes an arcuate edge that fits in only one orientation against a curvilinear edge of a boss on the cylinder head. In one described embodiment, the locator is a circular ring adapted to be installed over an exhaust guide.
Patent CA-2395478-A1 (CA)
Title: Method and composition for the prevention of high temperature corrosion due to alkali sulfates and alkali chlorides
Inventor: SCHOFIELD KEITH
IPC: B01J19/00
Filed: 2001-02-01
Abstract: An additive to a flame reaction is provided which forms noncorrosive deposits on cooler metal surfaces which are more stable than Na2SO4 or K2SO4. The additive preferentially combines with the sodium or potassium, and sulfates of these will not be formed. By adding tungsten to the flame, a complex sodium tungstate is produced on the surface of the cooler metal object in a dense form and corrosion is inhibited. Deposition appears to closely reflect the relative thermodynamic stabilities of these salts and follows the order Na2WO4 > Na2SO4 > NaCl > Na2CO3. The flame sulfur or chlorine do not remain on the surface in association with the alkali metal. Tungsten can be added in any form desired to the combustion system. The flame processes all chemical tungsten precursors as equivalent sources of tungsten. Suitable salts that are readily available are ammonium metatungstate, paratungstate, or tungstate, tungsten hexacarbonyl, tungsten oxides, tungstic acid or any organo-tungsten compound. The level of tungsten preferably present at an atomic concentration is equal to 1.5 to 2 times that of the sodium in the specific flame environment and possibly a little higher for potassium. The nature of the fuel and possible alkali reduction schemes will control the quantity and mixing method of the additive. The additive may be directly mixed into the fuel or injected into the burned gas regions of the combustor. Ta and Nb also appear as possible substitutes for W in the invention.
Patent CA-2396261-A1 (CA)
Title: Method and system for fault tolerant media streaming over the internet
Inventor: LEWIN DANIEL M
IPC: H04L69/40
Filed: 2001-01-02
Abstract: A replication process to provide fault tolerance for a streaming signal in a computer network. In one embodiment, the original or source signal is sent to several splitters which, in turn, each make copies of the signal and send the copies into a second layer of devices, which are referred to as "concentrators". A given concentrator receives as input one or more copies of the source signal. In a preferred embodiment, a given concentrator receives two copies of the source signal from at least two different splitters. The concentrators process the incoming streaming signal copies, for example, by merging them into a single or composite copy of the original source signal according to a given processing algorithm. The output of a given concentrator may then be fed into a splitter, with the process then being repeated if desired to make an arbitrary large number of copies of the signal. At the end of the replication process, the output of a splitter or a concentrator is fed directly or indirectly to an end user. The replication process is fault-tolerant, and thus the end user's signal is not interrupted regardless of signal or equipment problems within the distribution mechanism.

Filed: 2002-06-26
Abstract: This invention provides a clutch engagement detecting apparatus, which can accurately detect the state of engagement of a clutch using a helical spline engagement structure, and a single-shaft combined plant having it, and is constructed as follows: If the difference between the detected value of the rotational speed of a gas turbine and the detected value of the rotational speed of a steam turbine is not more than a detection error by the time a predetermined time elapses after load is charged into the steam turbine, it is determined that the clutch is engaged.  If the detected value of the rotational speed of the steam turbine exceeds the detected value of the rotational speed of the gas turbine by a predetermined rotational speed a or more, or if the detected value of the rotational speed of the steam turbine falls short of the detected value of the rotational speed of the gas turbine by a predetermined rotational speed P or more after detection of clutch engagement, it is determined that the clutch is abnormal.  Alternatively, steam turbine rotation pulses are counted for each constant number of gas turbine rotation pulses, and subtraction or addition is done based on the counted value to obtain the relative rotation angle between the steam turbine and the gas turbine, thereby detecting clutch engagement.
