Title: Error detection system
Inventor: GOULD ADAM F
IPC: H03M13/41
Filed: 1991-09-03
Granted: 1996-12-31
Abstract: An error detection system for a discrete receiver. The error detection system indicates bad frames of binary information signals which contain distorted bits in densities so great as to cause a convolutional decoder to generate an incorrect, decoded signal. A signal decoded by a convolutional decoder is re-encoded by an encoder, and the re-encoded signal is compared with the signal received by the receiver. When portions of the re-encoded signal differ too greatly from the actual, received signal, a bad frame indication is generated.

Abstract: A precision depth spindle is mounted to rotate within a cartridge but is restrained against axial movement with respect to the cartridge. The cartridge is mounted for axial sliding movement within a housing, but cannot rotate with respect to the housing. A tool chuck is fixed to one end of the spindle for movement with the spindle, the tool chuck supporting a cutting tool. A spindle stop is mounted to the tool chuck and can rotate with respect to the chuck. Thisallows the spindle stop to be maintained stationary while the tool chuck and thecutting tool rotate. The spindle stop is finely adjustable axially with respect to the tool chuck, thus determining the depth to which the cutting tool will enter a workpiece. The cartridge has a limited axial motion range with respect to the housing, and both the spindle and cartridge are urged toward the workpiece with respect to the housing by a suitable spring or pressure means.

Title: Double solenoid valve actuator
Inventor: VANRENS RUSSELL J
IPC: F16K31/06
Filed: 1993-01-15
Granted: 1998-10-27
Abstract: Apparatus for moving a reciprocating object, such as a spring biased poppet valve, between a rest and a second position.  The apparatus includes two solenoids, each of which has a core, with one of the solenoids having a larder core and imparting greater force than the other.  The solenoids are mounted in line with one another so that the core of one solenoid is adapted to contact the core of the other, with the latter being adapted to contact the object.  A first solenoid provides a driving force to the object to move it in opposition to a biasing force and the second solenoid holds the object in its moved position when the first solenoid is de-energized.  When the core of the first solenoid is in its rest position, it is out of contact with the core of the second solenoid and this enables the biasing force of the object to rapidly move to its rest position upon de-energization of the second solenoid.

Title: Electronic alarm for avoiding collision with animals in a non-destructive manner
Inventor: CARLO LOUIS D
IPC: A01M29/18
Filed: 1993-07-05
Granted: 1996-07-16
Abstract: An electronic alarm is disclosed for use in a moving vehicle which generates ultrasonic sound for preventing animals from moving into the path of the vehicle.  The device includes a simplified driver circuit for generating electrical impulses in the form of square waves having constant peak-to-peak voltages. The driver generates the square waves with periodic, sequentially increasing wave frequencies followed by sequen-tially decreasing wave frequencies.  A coupling transformer converts the square waves into electrical sine wave voltages having high peak-to-peak voltages to cause a piezo-electric transducer to emit intense, ultrasonic sounds of periodically increasing frequencies followed by periodically decreasing frequencies simulating the warble effect of a siren without excessive heating and premature failure of the transducer. The ultrasonic warble effect confuses the animal to prevent inad-vertent movement by the animal into the oncoming vehicle's path without injury to the animal.

Abstract: The loadflow computation method of the present invention called Fast Super Decoupled Loadflow (FSDL) is characterized by the use of 1) the slack-start whereby the same voltage magnitude and angle as those of the slack-node are used for all the other nodes as an initial guess solution, and thereby reducing almost all effort of mismatch calculation in the first P-.theta. iteration, and PV-nodes voltage magnitudes are assigned their known values while updating voltage angles after P-.theta. iteration, 2) the restricted rotation angles to the maximum of -36 degrees for improved convergence in the situations of low voltage solution, 3) the gain matrices [Y.theta.], and [YV] whose elements are defined independent of rotation angle, 4) the same indexing and addressing information for storing both the constant gain matrices [Y.theta.], and [YV]  factorized using the same ordering regardless of node types as they are of the same dimension and sparsity structure.   In addition, the FSDL method is characterized in the modification of the real power mismatch at PV-nodes by a factor K p= Absolute (B pp/Y.theta.pp) such that RP  p = .DELTA.P p /(K p V p) in order to correct the Super Decoupled Loadflow model at PV-nodes in P-.theta. sub-problem thereby achieving improved convergence and consequent processing acceleration to a great extent. Also while solving for [.DELTA.V] in Q-V sub-problem, all the rows and columns corresponding to PV-nodes in factorized gain matrix [YV] are skipped from calculation.   In addition to listed four characteristics in the beginning, an alternate Novel Fast Super Decoupled Loadflow (NFSDL) method is characterized in that it employs overlap update of the voltage angle corrections at PV-nodes. It involves calculation of angle corrections at PV-nodes along with voltage magnitude corrections at PQ-nodes in Q-V sub-problem in addition to regular angle corrections in P-.theta. sub-problem as illustrated in Fig.4. This improves convergence and achieves consequent processing acceleration of the same order as that of the FSDL method.

Title: Sedimentation type solid-liquid separator
Inventor: HARATO TAKUO
IPC: B01D21/01
Filed: 1994-06-14
Granted: 2005-01-18
Abstract: The present invention is directed to a sedimentation type solid-liquid separator. The separator operates in the following manner. The slurry subjected to aggregation processing by a line mixer is supplied to a slurry feed member via a slurry supply passage and then fed radially outward from slurry fed outlets within a sedimentation tank. Therefore, liquid flow hardly takes place below the slurry feed member and the settling velocity of the solid is increased. The slurry feed member is arranged close to the boundary face of the thickened slurry zone, and thus the settling distance of the solid is shortened. Accordingly, the residence time of the solid is shortened to a great extent. In addition, the sedimentation tank can be constructed to be sealed and solid-liquid separation can also be performed under a pressurized state.
