Title: Slag control shape release apparatus for molten metal vessels
Inventor: FORTE GARY F
IPC: B22D43/00
Filed: 1993-06-11
Abstract: 2137909 9325335 PCTABScor01 A slag control shape (32) is releasably mounted on a cover (28) for a molten metal vessel (10). An actuator (60) is connected to a slag control shape release member to retract the release member from a first position engaged with the slag control shape to a second position separated from the slag control shape allowing the slag control shape to freely drop into the molten metal receptacle. The actuating end of the actuator is located at an easily accessible operator position for remote actuation of the release member. In one embodiment, the actuator is a flexible cable (60) attached at one end to the release member mounted on the cover and having a second end (66) located remote from the cover at an easily accessible operator position. In another embodiment, one end of a cable wound in a plurality of turns about a rotatable shaft mounted in a reel (212) is attached to the slag control shape. A  spring (230) biasingly engages the shaft to control the rate of rotation of the shaft and thereby the rate of payout of the cable and the rate of descent of the slag control shape into the molten metal vessel. A detector (242) counts the revolutions of the shaft as the cable is paid out to measure the distance the slag control shape has descended into the vessel.

Title: A method and system for computer-controlled gear shifting
Inventor: BROWNING DAVID L
IPC: G06F17/00
Filed: 1993-06-15
Abstract: A method and system for computer-con-trolled shifting of a bicycle is provided. In pre-ferred embodiments, the present invention provides a computer system that detects speed, hub speed, and crank speed, determines the optimum bicycle gear selection to maintain a desired cadence, and shifts the bicycle to the optimum bicycle gear. The computer also inputs a shift up and shift down sig-nals from the cyclist to override the computer-se-lected gear. When the cyclist indicates a shift up or down, the computer adjusts the desired cadence.     The computer determines the gear selection to en-sure a uniform transition from the current gear to the next gear. The computer ensures that when shifting from the current gear to the next gear, the bicycle does not transition through a gear that is not between the current and next gears.

Title: Curved drilling apparatus
Inventor: WARREN TOMMY M
IPC: E21B17/20
Filed: 1995-03-21
Abstract: A rotary drill bit for drilling a curved subterranean borehole.  In one embodiment, the drill bit comprises a side portion, a plurality of cutting elements that produce a lateral force on the drill bit in response to the rotation of the drill bit in the borehole, and bearing means. The bearing means is located on the side portion of the drill bit and contacts the borehole wall during drilling to receive a reactive force that is from the borehole, that is in response to the lateral force and that is directed to a location adjacent to the uphole end of the side portion of the drill bit. The reactive force and the lateral force form a downhole-moment that is about the drill bit and that is opposed by an uphole-moment having a force component that is directed at the flexible joint. The uphole end of the bearing means is located relatively close to the cutting elements such that the magnitude of the downhole-moment and the magnitude of the uphole-moment are minimized.

Patent CA-2161044-A1 (CA)
Inventor: KENNEDY THOMAS A
IPC: G01S13/86
Filed: 1995-10-20
Abstract: A system (10) and method (20) that provides for all-weather precision guidance of conventional air-to-surface weapons. The system (10) and method employs a coherent monopulse radar (12) disposed on a launch platform (11) and a noncoherent passive (receive only) radar (14) disposed on the weapon (13). The synthetic aperture radar (12) generates a synthetic aperture radar monopulse map of an area around the target (15). The radar (12) is used designate the location of the target (15), and transmit a sequence of alternating sum and simultaneous azimuth and elevation difference patterns centered on the target (15). The weapon (13) includes a guidance system and seeker (14) that is responsive to guidance commands transmitted by the synthetic aperture radar (12). The guidance system and seeker (14) receives reflections of the alternating sum and combined azimuth and elevation difference pattern from the target (15), and the sum pulse is used by the weapon (13) to acquire and track the azimuth and elevation difference pattern null on the target (15) to fly an optimum trajectory to the target (15). One method for guiding a weapon (13) to a target comprises the following steps. A synthetic aperture radar (12) is used to generate (21) a SAR monopulse map of a target area and designate a target (15) therein. The weapon (13) is then launched (23) toward the target (15). The radar (12) is used to transmit (24) an interleaved sum and simultaneous azimuth and elevation difference pattern guidance pulse train at the target (15). The reflected interleaved sum and simultaneous azimuth and elevation difference pattern is received (25) from the target (15) at a seeker and guidance system (14) on the weapon (13). The sum pattern is used by the weapon (15) to lock (26) onto the converging null, and is used by the launch platform (11) to provide closed loop tracking of the target (15) during guidance illumination. After weapon null lock-on, steering commands are generated (27) to cause the weapon (13) to fly an optimum trajectory to the target (15).

Inventor: SUNDE EGIL
IPC: C09K8/512
Filed: 1994-05-25
Abstract: A plugging liquid for plugging of a zone of a subterranean formation around a drill hole, consisting of an emulsion comprising (a) a continuous phase containing a hydrophobic liquid, an emulsifier and a crosslinking agent for a polysaccharide, and (b) a discontinuous phase containing water and a polysaccharide. A variant of the plugging composition contains in addition a weighting material in the discontinuous phase. Also described is a method for preparing the plugging liquid and a method for plugging a zone of a subterranean formation penetrated by a drill hole in fluid communication with the zone, according to which method the new plugging liquid is injected into the zone via the drill hole and is subjected to high shear forces in the drill hole, whereby the polysaccharide and the crosslinking agent are brought into contact with one another with resulting initiation of a crosslinking of the polysaccharide and a setting of the plugging liquid. When the drilling liquid contains a weighting material it is primarily used to inhibit or prevent an undesired blow-out in or from a well.

The process reaction temperature can vary from about 100 ~C to about 650 ~C and the contact time can vary from about 0.01 to 20 seconds. Preferably, the reaction temperature is from about 150 ~C  to about 450 ~C and the contact time is from about 0.1 to 1.0 seconds. The CO/CO2 ratio and the Cl2/HCl ratio in the gaseous effluent can be varied through selection of at least two impregnating metals with at least one exchanged metal in the aluminosilicate zeolite or by the use of at least one impregnating metal with at least two exchanged metals in the aluminosilicate zeolite.

Inventor: PASHANDI HAMID REZA MIRZAHASSA
IPC: B60Q1/52
Filed: 1996-10-08
Abstract: Automatic Hazard signal alarm deals with and warns of the lack of stability and balance of the automobile at the time of the instant stops in the application of the brakes. It warns of the lack of stability and balance at the time of slipping during fast turns as well as on uneven or steep downhill roads. It also gives sufficient advanced warning to the other vehicles in the proximity of the automobile having such a system.  The system contains four cylinders, each of which works with a magnetic piston. Each magnetic piston could move in the direction of the cylinder whereby the magnetic switches as sensors situated at one end of each cylinder activate the system by the effect of the magnetic pistons. A spring in each cylinder determines the limit of the movement of each piston and a regulating screw which is situated on the other end of each cylinder regulates the movement and adjusts the initial location of the pistons by the connected spring. This mechanism sets up the sensitivity of the system.
