Granted: 2013-09-03
Abstract: A method and apparatus for predicting and controlling secondary kicks, while dealing with a primary kick experienced when drilling an oil and gas well. The method includes a step of determining whether a different pressure per cubic meter of mud pit volume has been caused by a secondary kick by subtracting shut in drill pipe pressure (SIDPP) from shut in casing pressure (SICP) and dividing the derived sum by a kick volume in KPa per cubic meter from the primary kick. A further step is then taken of increasing casing pressure until casing pressure equals pit gain times (X) rate of change in casing pressure per cubic meter of pit gain plus (+) SIDPP.

Title: Brake evaluation gauge
Inventor: GRAHAM MYRON ROY
IPC: G01L5/28
Filed: 2005-09-08
Granted: 2010-12-07
Abstract: A brake evaluation gauge is useful to determine a brake lining thickness and/or brake drum wear. Depending on the particular embodiment selected, one of a thickness measurement, a percentage of brake life left, a pass or a fail indication may be indicated for the thickness of the brake lining. A first end of a gauge is inserted between a brake shoe table and a brake drum of applied air brakes to provide this reading. Furthermore, a recess in the gauge is placed over a ridge created by wear of the brake lining on the brake drum. If the ridge contacts the interior surface of the recess, then excessive wear of the brake drum is indicated.

Title: Apparatus and method for retracting awning
Inventor: GOTH MARK
IPC: E04H15/58
Filed: 2005-11-16
Granted: 2010-08-31
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.
Patent CA-2528099-C (CA)
Inventor: PACHECO PEDRO ALVARES RIBEIRO
IPC: E01D21/00

Granted: 2009-09-01
Abstract: The present invention refers to a gantry for use in the construction process of bridges, viaducts and other structures, said gantry being equipped with a system that automatically adjusts the prestressing of the said gantry's structure in accordance to the external actions being applied on it when loadings occure. The adjustment of the prestressing is achieved through the use of at least one sensor (2) that monitors the structure, said sensors conveying those measurements to a controller (6), said controller (6) being then capable of activating at least one actuator which alters the tension of the structure's prestressing cable or cables. Amongst the many advantages of the present invention, one is the possibility of applying a large amount of prestressing without this implying undesirable deformations in the main structure (1) when exterior loads are not applied.

Title: Method and apparatus for accelerating the expiration of resource records in a local cache
Inventor: CHESHIRE STUART D
IPC: H04L69/14
Filed: 2004-04-29
Granted: 2008-10-28
Abstract: One embodiment of the present invention provides a system that facilitates reconfirmation of resource records in a cache. The system starts by retrieving the resource record at a client and attempting to establish communication using the data in that resource record. In the event that communication is not successful, the system responds by issuing one or more queries for the resource record in question. The system then waits for a response to the query. If the response to the query is not received in a pre-determined amount of time, the system invalidates the resource record. The response from the device is a multicast response, thereby allowing other clients to update corresponding resource records in their local caches without querying the device, and thus saving network bandwidth.

Abstract: A method of flow forming sintered metal parts. The first step is forming a round disk (15, 16, 17) by conventional powder metal process. The disk (15, 16, 17) can be a donut shape part with or without a flange on one side of its outer diameter. The disk (15, 16, 17) can then be copper impregnated or used as is, depending on the requirements. The disk (15, 16, 17) is placed in a spinner held (T) in proper tooling (20) and grooves are spun in its outer diameter. The spinning can be done with a finishing roller or by a pre-finishing roller, followed by a finishing roller. This process not only creates a part with great accuracy, it also densifies and eliminates the powder metal porosities on the surface layer by the pressures inserted in spinning.
