Inventor: GIANZERO STANLEY C
IPC: G01V3/28
Filed: 1990-12-20
Granted: 1996-12-10
Abstract: High resolution induction logs (28) are obtained through borehole casing (15) by magnetically saturating the casing (15), logging with a tool (10) having different transmitter (35a, 35b)-to-receiver (40) coil spacings, and determining the formation (30) conductivities as a function of the coil spacings, coil frequency, and phase difference between the signals at these spacings.

Granted: 1997-03-18
Abstract: A method for preparing a vinyl chloride resin comprises the steps of copolymerizing 80 to 99.9% by weight of an alkyl acrylate and/or an alkyl methacrylate whose homopolymer has a second-order transition temperature of not more than -10°C , 20 to 0.1% by weight of allyl methacrylate and/or triallyl isocyanurate and 0 to 20% by weight of a monomer copolymerizable with these monomers to form an acrylic rubbery copolymer having an average particle size ranging from 0.01 to 0.5 µ m and then graft-copolymerizing vinyl chloride monomer to the acrylic rubbery copolymer. The graft copolymerized resins obtained according to the foregoing method can be mixed with a variety of additives such as heat stabilizers, lubricants, processing aids, antioxidant, fillers, ultraviolet absorbers, pigments or the like which are commonly employed in the fabrication of vinyl chloride resins and can be processed and/or molded according to the usual manner. The graft copolymerized resins are excellent in not only impact resistance but also tensile properties and, therefore, these resins can be used for manufacturing construction materials, high impact pipes or the like in which well-balanced impact resistance and tensile properties are required and can provide products which can be used in the open air.

Title: Attitude control system for momentum-biased spacecraft
Inventor: UETRECHT DAVID S
IPC: B64G1/28
Filed: 1991-05-06
Granted: 1993-11-09
Abstract: ATTITUDE CONTROL SYSTEM FOR MOMENTUM-BIASED SPACECRAFT           ABSTRACT OF THE DISCLOSURE An attitude and nutation control system (30) for a momentum-biased vehicle (19) having roll, pitch, and yaw axes which employs a normal mode estimator  (32)  which predicts steady-state values for roll attitude, roll rate, and yaw rate.   The normal mode estimator (32) receives instantaneous roll attitude information from an earth sensor (34) and optionally receives roll and/or yaw rate information from roll gyro (35a) and yaw gyro (35b).  A logic circuit (36) coupled to the normal mode estimator (32) generates correction signals when the steady state values for roll attitude, roll rate,  and yaw rate are outside predetermined limits.  A plurality of thrusters (14a-d)  produce  torque  for bringing  the  steady-state values for roll attitude, roll rate, and yaw rate within predetermined limits.  A sample/hold-off control circuit (68)   samples   correction   signals  between  thruster activations while a optimal thruster selection logic (70) employs a linear program to compute torques associated with changes in the correction signals for use by the normal mode estimator (32), as well as activating selected thrusters (14a-d).

Title: Adaptive equalizer with midburst correction capability
Inventor: NAKAI TOSHIHISA
IPC: H04B3/06
Filed: 1991-05-15
Granted: 1997-11-25
Abstract: An adaptive equalizer in a digital receiver filters differentially encoded data bursts containing known data preceded and followed by user data.  A storage means saves and restores filter coefficients and other values so that the known data can be filtered repeatedly.  As the known data are repeatedly filtered, a known-data generating means generates different differential encodings of the known data as desired data which are compared with the filtered values to obtain error values for use in updating the filter coefficients.  A comparator means selects the encoding that produces the smallest cumulative error.  The known data are then filtered once more, using the selected encoding as desired data, after which adaptive filtering of user data continues.

Title: Gear puller
Inventor: CHEN ZUI-NIEN
IPC: B25B27/02
Filed: 1991-10-03
Granted: 1995-08-22
Abstract: A gear puller has a body that houses an hydraulic mechanism formed by a pair of piston-and-cylinder assemblies, one assembly being positioned toward a head end of the body, and the other assembly being positioned toward a base end of the body.  An annular oil chamber extends around the head end of the body.  A first check valve sits in a passage between the oil chamber and the cylinder of the one assembly, and a second check valve sits in a passage between the cylinder of the one assembly and the cylinder of the other assembly.  A lever and a rod connected to the piston of the one assembly actuate that assembly.  A series of pawls, connected to the puller body, and a rod connected to the piston of the other assembly define an arrangement for pulling a gear off of a pole. A spring housed in the body biases the piston of the other assembly away from the base end of the body.  A rotatable bolt extends across a flow passage between the cylinder of the other assembly and the oil chamber, controlling oil flow between the two.  Use of the gear puller involves positioning the pawls around the gear and bringing the rod of the other assembly against the pole.  Actu-ation of the lever relative to the head end of the body moves oil from the cylinder of the one assembly to the cylinder of the other assembly, and results in the gear moving relative to the pole.  The bolt is then loosened, allowing the oil in the cylinder of the other assembly to be pushed by the spring into the oil chamber.  The bolt is then tightened before further use of the gear puller.
