Patent CA-2488092-A1 (CA)
Title: Method of formulating and using a drilling mud with fragile gels
Inventor: SIEMS DON
IPC: C09K8/34
Filed: 2003-06-18
Abstract: A method for drilling, running casing, in, and/or cementing a brothel in a subterranean formation without significant loss of drilling fluid is disclosed, as well as compositions for use in such method. The method employs a drilling fluid comprising a fragile gel or having fragile gel behavior and providing superior oil mud rheology and overall performance. The fluid is especially advantageous for use in deep water wells because the fluid exhibits minimal difference between downhole equivalent circulating density and surface density notwithstanding differences in drilling or penetration rates. When an ester and isomerized olefin blend is used for the base of the fluid, the fluid makes an environmentally acceptable and regulatory compliant invert emulsion drilling fluid. The fluid preferably contains no organophilic clays.

Inventor: MATSUMOTO TAKEO
IPC: B30B15/14
Filed: 2004-03-23
Abstract: A press-forming machine has drive shafts each pressing each of three or more press points and displacement-measuring means for measuring near each press point the displacement of the press point. Among the drive shafts, the shaft located in the center has a larger gap between itself and a pressing plate than other shafts. During press forming in a trial step, in order to maintain the entire pressing plate at a desired displacement position, positional displacement near each press point is measured by the displacement-measuring means, and control data are supplied to each drive source for driving the drive shafts and drives the pressing plate. After that, final press forming is carried out in accordance with the result of the trial press forming. As a consequence, the gap in the drive shaft prevents a central drive source from being overloaded.

Title: Apparatus and method for retracting awning
Inventor: GOTH MARK
IPC: E04H15/08
Filed: 2005-11-16
Abstract: An apparatus and method for retracting an awning. A sensor detects an awning acceleration caused by wind impacting the awning, and generates a signal having an amplitude corresponding thereto. When the signal exceeds a certain threshold, the awning is retracted. The signal's amplitude may be converted into a frequency, and the frequency compared to the threshold. The signal typically must exceed the threshold for a set period of time to trigger awning retraction. A  second threshold may dictate a maximum instantaneous or peak acceleration; when the signal exceeds this second threshold, regardless of the duration during which the second threshold is exceeded, the awning is retracted.
