Granted: 2003-12-02
Abstract: L'invention porte sur une combinaison outil de forage /outil de fraisage de métaux (10) destinée à être utilisée pour effectuer une amorce de déviation une seule passe à partir d'un tubage de puits de forage. Cette combinaison fraise/trépan (10) présente une première structure coupante relativement plus durable (20a, 22) telle qu'une structure en carbure de tungstène, et une seconde structure coupante relativement plus dure (20b, 24) telle qu'une structure en diamant polycristallin. La première structure coupante (20a, 22) est mieux appropriée au fraisage du tubage métallique tandis que la seconde (20b, 24) est mieux appropriée au forage d'une formation souterraine, notamment d'une formation rocheuse. La première structure coupante (20a, 22) est placée de sorte que la première fraise le tubage métallique (20a, 22) tout en évitant à la seconde (20b, 24) d'être en contact avec le tubage. La première structure coupante (20a, 22) peut subir une usure lors du fraisage du tubage. La seconde structure peut ensuite être utilisée pour forer la formation rocheuse.

Title: Integrated method for protecting logs and green lumber from sapstain, mould, and decay
Inventor: YANG DIAN-QING
IPC: A61L2/00
Filed: 1999-05-26
Granted: 2003-05-06
Abstract: The present invention relates to an environmentally acceptable wood protection system for treating wood against sapstain, mould and decay. The wood or wood product is treated with a biocontrol agent having a high pH tolerance and an alkaline solution. Biocontrol agents that do not discolour wood may be introduced onto wood or wood products to prevent sapstain and mould. The biocontrol agent grows on the wood surface and protects the wood against attack by stain or decay fungi. The application of an alkaline solution containing a biocontrol agent having a high pH tolerance to the wood product is very effective in controlling stain or decay fungi. The alkaline solution raises the pH of the wood to a level which impedes growth of other wood-inhabiting fungi but does not inhibit colonisation of the wood by the biocontrol agent.

Granted: 2009-01-20
Abstract: A deep well pumping system includes a pump, a motor coupled to the pump and a control unit coupled to the motor. The control unit comprises a timer for measuring time. The system is configured to initiate a start sequence of the motor and determine whether a timer valve exceeds a first valid time range. If the timer valve exceeds the first valid time range, the system determines whether a motor frequency is less than or equal to a first valid frequency range. If the motor frequency is less than or equal to the first valid frequency range the system alters the signals applied to the motor. The system may be used to eliminate an obstruction from the pump.

IPC: B62D31/02
Filed: 2000-02-03
Granted: 2003-01-07
Abstract: A public transit vehicle has a vehicle body having a roof defining an interior ceiling surface, two side walls each extending longitudinally of the vehicle including an upper side wall portion connecting to the roof and a row of windows underneath the upper portion, a central aisle and two rows of seats each on a respective side of the aisle and along the side wall at the windows.

Between two stanchion mounting rails is provided a central ceiling panel dropped from the roof to define an air supply duct longitudinally along the aisle above the passengers. This is supplied with ventilation air by a roof mounted system and communicates by individual sub-ducts with a series of fans in the side walls. A flap valve at the fan can be operated to cause heated air when required to be supplied through the main side wall posts to bottom discharge openings at the bottom interior panels or to cause cooled air to be supplied to a duct along the top of the windows.

Title: Improved electrochemical sensor design
Inventor: MUSHO MATTHEW K
IPC: G01N27/327
Filed: 2000-04-17
Granted: 2005-09-20
Abstract: Disclosed is an improved electrochemical sensor having a base bearing a working and reference electrode which provides a flow path for a fluid test sample. The working electrode has a reaction layer on its surface which contains an enzyme capable of reacting with an analyte to produce electrons which are received by the working electrode. The base is mated with a cover to form a capillary space into which the test fluid is drawn. The improvement involves configuring the working and reference electrodes so that a major portion of the reference electrode is located downstream on the flow path from the working electrode with the exception of a small sub-element of the reference electrode which is in electrical communication with the primary portion of the reference electrode and located upstream of the working electrode. This configuration provides the sensor with the capability of sending a greatly reduced electrical signal to the device's detecting element in the event that the capillary space is incompletely filled with test fluid. This reduced signal can be manipulated to produce an error signal which affirmatively apprises the device's user that such incomplete filling has occurred.

Title: Design for scalable network management systems
Inventor: SRINIVASAN SANJAY
IPC: H04L12/24
Filed: 2000-06-16
Granted: 2007-05-15
Abstract: A system and methodology for building highly scalable Network Management Systems (NMS)s for the management of large voice and data networks is provided. The NMS of the present invention is designed to manage a plurality of network elements communicating through network controlled links. The elements are combined into management groups of no more than n elements. A first functional subsystem controls and manages the communication functions associated with a first group of elements. Each function or process inside the subsystem is guaranteed to communicate with only one instance of every other type of process or function. As additional network elements are added to the system, additional management groups are also added, one functional subsystem for every management. group of elements. The plurality of other functional subsystems are substantially the same as the fust functional subsystem. Limiting the management process to intra-subgroup communications greatly simplifies expansion of the system. When a total of m management groups exist, at least (m - 1) functional subsystems are replicated from the first NMS subsystem. Thus, the network is scaled up by using size-limited subsystems.
