Title: Sensor fault detection, isolation and accomodation
Inventor: ADIBHATLA SRIDHAR
IPC: G06F19/00
Filed: 2001-08-09
Granted: 2008-01-29
Abstract: A sensor in an engineering system (10) can be tested to detect, isolate and accommodate faults. Initially, a modeled sensor value (M) of each actual sensor value (S) is generated as a function of a plurality of other sensors. An absolute value of a difference between the actual sensor value (S) and the modeled sensor value (M) is then computed (14) and compared (16) to a predetermined threshold (T). A sensor fault is detected if the difference is greater than the predetermined threshold (T). Once a sensor fault is detected, it is isolated using hypothesis testing (22) and maximum wins strategies (26). After the fault is isolated (20), the fault is accommodated (22) by substituting the modeled sensor value (M) for the actual sensor value (S).

Abstract: To roll form a worksheet (32) by a turret punch press, at least one pair of coacting tools (34, 36) are mounted to the opposed turrets (46, 48) so that when those tools are rotated to the work location, they cou ld be driven to a predetermined relative distance towards each other to make contact with the workpiece (32). The depth of the formed shape is determined by the relative distance the coacting tools (34, 36) are driven towards each other. By moving the worksheet (32) at the same time that the coacting tools are making contact with the worksheet, roll forming of the worksheet is effected. By providing the coacting tools in the opposing indexing stations and synchronously rotating those stations, a complex pattern can be roll formed on a worksheet .

Patent CA-2387308-C (CA)
Inventor: SCHMIDGALL RONALD D
IPC: E02D29/12
Filed: 2002-05-24
Granted: 2007-07-24
Abstract: As a part of the manufacture of concrete prodcts, such as concrete pipe, manholes and the like, the joint rings applied during the casting process must be removed. The invention relates to a joint ring removal system in which a vertically oriented concrete product, containing a joint ring, is gripped to hold the product stationary while a joint ring pulling force is applied. Then, a shocking force is applied laterally to the joint ring to free it from the concrete joint. The amount of pulling force applied to the joint ring is less than that required to separate the joint ring from the concrete while the shocking force is applied in a direction transverse to the pulling force so that no harmful tensile shocking forces are transmitted to the concrete joint. The pulling force on the joint ring is variably applied and timed with the shocking force.

Abstract: A universal setting tool comprises a collet housing for mounting within a chuck mechanism of a rotary drive tool. An axially oriented bore extends into the interior of the collet housing, and a radially expansible and contractible coil spring is disposed within the bore. After the free end portion of an anchor member has been inserted into the spring member, the rotary drive tool, and therefore the collet housing member, is rotated in the clockwise direction so as to effectively cause radial contraction of the spring member such that the spring member tightly engages the anchor member. Rotation of the rotary drive tool in the opposite direction releases the grip of the spring member upon the anchor member. The spring member can engage different anchors having different diametrical extents.

Abstract: The present invention provides a hanger for either casing or tubing strings that electrically insulates the internal suspension system of the hanger from the hanger's external seal. Electrical power is typically transferred through a hanger via the internal suspension system. If electrical umbilicals are used, connecting devices may be located within the internal suspension system for connecting an upper and lower umbilical and transferring power through the hanger. If a rigid tubular conductor is used, the suspension system may be ported to allow the passage of electrical feedthroughs or, in the case of tubing hangers, the tubing itself may be charged with electrical power. By insulating the suspension system from the external seal, potential electrical hazards are eliminated.
