Granted: 1991-07-23
Abstract: APPARATUS AND METHOD FOR GRAVITY CORRECTION         IN BOREHOLE SURVEY SYSTEMS         Abstract Disclosed is an inertial navigation borehole survey system wherein the signals supplied by accelerometers (40) that are contained within the borehole survey system probe (10) are corrected for gravitational gradients encountered as the probe (10) travels through a borehole (12). The gravity correction is effected in the survey system signal processor (24) and is based on a gravity gradient signal that mathematically corresponds to:        where f represents the specific force due to gravity; f0 represents the specificforce of gravity at wellhead (20) of borehole (12); R0 represents the average radius of the earth; P(H) represents the local density of the geological formation penetrated by the borehole as a function of depth H; and Pave represents the mean density of the earth. In utilizing the gravitational gradient to generate agravity correction signal, the signal processor (24) effects a summation processthat mathematically corresponds to:                    where (.DELTA.H)i represents the depth change between the "ith" signal processing cycle and the nextmost antecedent processing cycle, and, the summation range extends from the first signal processing cycle performed during the borehole survey through the final signal processing cycle of the borehole survey operation.

Abstract: ABSTRACT OF THE DISCLOSURE The majority of combination lifts and carrying frames for use on vehicles such as pickup trucks are complicated structures including fixed and movable frames, pulleys, chains and even winches.  A relatively simple combination lift and stand for use on such a vehicle includes an L-shaped frame for carrying by a vehicle in a collapsed condition with the vertical arm of the L near the cab of the vehicle; and extensible legs pivotally connected to each end of the frame for rotation between stored and inclined, ground engaging positions, whereby, when the legs are rotated from the stored to the ground engaging position and the vehicle is driven in reverse, the frame is pushed to an erect, stand position, and subsequent forward movement of the vehicle leaves the device alone in the erect, stand position.          The procedure can be reversed, by driving the vehicle in reverse beneath the stand, attaching the stand to the vehicle and driving forward to cause the stand to collapse onto the vehicle.

Title: Safety valve actuator assembly

IPC: F16K17/00
Filed: 1988-04-11
Granted: 1993-05-18
Abstract: ABSTRACT     An emergency shut-down system to close a gate valve in a pipeline and therefore terminate flow.  The closing action is initiated when a pilot valve senses pressure in the pipeline outside predetermined limits.  This reduces the signal pressure in the system which, in turn, causes a fluid dump from the gate valve actuator which closes the gate valve and terminates fluid flow in the pipeline.  The system is reactivated by manually pumping the system which re-opens the gate valve and allows fluid flow in the pipeline to again continue.

Granted: 1991-04-23
Abstract: ABSTRACT OF THE DISCLOSURE A card cage includes upper and lower support members which define a slot for receiving a printed circuit board. An engagement mechanism includes one or more handles pivotally mounted on the front of the card cage.  Each handle, in turn, is pivotally attached to a rod which extends to the rear of the card cage and terminates in an extraction member which receives the rear corner of a circuit board.  When the circuit board is mounted in the card cage, the handle is pivoted to contact the forward edge of the board and urge it into position in the cage, thereby urging contacts along the rear edge of the board into engagement with a connector at the rear of the card cage. When the board is to be removed from the card cage, the handle is pivoted in the opposite direction, enabling the extraction member at the rear to push the board forwardly out of engagement with the connector and permitting the board to then be removed from the card cage.

Title: Process for shaping a material by hot isostatic pressing and titanium sheath usable in this process
Inventor: BONCOEUR MARCEL
IPC: B22F3/14
Filed: 1988-07-29
Granted: 1993-09-14
Abstract: DESCRIPTIVE ABSTRACT            The invention relates to a process for shaping a material by iso-static compression at a temperature of at least 1300°C of a powder of said material in a tight sheath.            The sheath is made from titanium or a titanium alloy and is inter-nally coated with tantalum in such a way that the sheath can be embrittled during hot isostatic compression, by the diffusion of tantalum into the titanium or titanium alloy, in the presence of oxygen.  In general, the titanium sheath is coated with tantalum by spraying in the presence of oxygen.            The use of such a sheath makes it possible to avoid the operation of eliminating the sheath chemically or mechanically conventionally necessary in such processes.     B 9491.3 MDT

Abstract: The invention concerns apparatus for molding thermoplastic tubing having solid annular ribs. The apparatus is of the type where a tubular mold is defined by cooperatively interengaged mold block of a pair of mold assemblies. An annular extrusion orifice for the tube extends into the mold tunnel and tubine is extruded about a mandrel. The invention provides an accumulator chamber in the region of the extrusion nozzle to provide for pressure differences which build up at that point. Thus, the effective volume of the accumulator chamber can compensate for the varying requirement for the thermoplastic material resulting from the varying radial wall thickness.
