Abstract: CROSSFLOW ROTARY CONE ROCK BIT                   WITH EXTENDED NOZZLES                   ABSTRACT OF THE DISCLOSURE      A three cone rock bit is disclosed having at least a pair of mini-extended nozzles extending from a dome portion of the bit.  Two 120° leg segments contain extended noz-zles, a third 120° segment is nozzleless.  The mini-extended nozzles convert hydraulic pressure to kinetic fluid flow energy with a minimum of flow disturbance, thereby delivering a concentrated flow of fluid against the floor of the formation and across the cutting face of the bit, sweeping detritus past the nozzleless 120° leg segment and up the borehole.  A centerjet mini-extended nozzle may additionally be positioned in the rock bit dome to further enhance borehole penetration.

Abstract: LIGHT-DRIVEN PHASE SHIFTER A light-driven phase shifter is provided for modulating a transmission light beam. A gaseous medium such as argon is provided with electron energy states excited to populate a metastable state. A tunable dye laser is selected with a wavelength effective to deplete the metastable electron state and may be intensity modulated. The dye laser is directed through the gaseous medium to define a first optical path having an index of refraction determined by the gaseous medium having a depleted metastable electron state. A transmission laser beam is also directed through the gaseous to define a second optical path at least partially coincident with the first optical path. The intensity of the dye laser beam may then be varied to phase modulate the transmission laser beam.

Abstract: DETACHABLE TINE CONSTRUCTION FOR A LOADER BUCKET                  ABSTRACT OF THE DISCLOSURE           A detachable tine comprises an elongate tine portion with a sharpened front end which can slide longi-tudinally into a bracket welded onto the upper surface of the lower wall of the bucket.  The bracket is formed by a channel iron laid on its side so that one side forms the base of the bracket which is welded to the upper surface.         The open side of the channel iron is closed by two straps one at the forward end and one at the rearward end of the channel leaving a central area open to allow the escape of material forced into the channel.   A transverse pin latches the tine in place when used and can be removed to release  the  tine.    The  positioning  of  the  brackets prevents  them  from  interfering  with  the  conventional horizontal cutting edge of the bucket when the tines are not used.

Abstract: RING TRANSMISSION SYSTEM          Abstract of the Disclosure A transmission system comprises nodes coupled in a ring via two paths having opposite transmission directions.  Bidirectional communications between any two nodes are provided in normal operation using both paths around a first, most direct, part of the ring.  In the event of a fault affecting such communications, a protection switch is made to maintain bidirectional communications between the two nodes using both paths around a second, remaining, part of the ring.  In this manner, each path can simultaneously carry both normal and protection switched signals.  In an embodiment of the invention, only the two nodes adjacent a fault need be aware of the fault, each of these nodes effecting a protection switch for signals terminated at the node and effecting a protective loopback for other signals needing protection.  The invention enhances the total capacity of the paths for carrying normal and protection switched signals.  A network may comprise a plurality of such ring transmission systems intersecting at at least one network node, the network node comprising a node of each ring and a cross connect switch for switching signals therebetween.         - i -

Title: Real-time bch error correction code decoding mechanism
Inventor: WENG LIH-JYH
IPC: G06F11/10
Filed: 1988-05-16
Granted: 1992-11-10
Abstract: ABSTRACT            This invention relates to error correction code decod-ing mechanisms for digital computer systems in general and more particularly to the decoding of Bose-Chaudhuri-Hocquenghem (BCH) error correction codes, including Reed-Solomon error correction codes.  The invention calculates the locations and values of the errors simultaneously and thus more quickly corrects the errors.          Using this technique, errors can be corrected in "real-time" even with fast data transfer rates.  The error locations and error values are found by evaluating various expressions, at values of x, where x is an element of the Galois Field used to encode the data. All values of x corresponding to possible error locations are systematically tried using an iterative evaluation technique which uses the values of each of the terms of the equations calculated for one value of x in evaluating the equations at the next value of x, in, for example, the error locator equation .delta.(x) = 0 where .delta.(x) is the error locator polynomial, to find all the exist-ing solutions to the equation.

Abstract: ABSTRACT         The proposed voltage control device features a power switch in the form of a transistor that is normally actuated for a constant switch-on time interval during each variable period interval (T).  The type of control required in this case comprises, conventionally, a monostable multivibrator, a controller, and a voltage/frequency converter.         The present control system is subordinated to an emergency control circuit which, supplanting a priority loop, intervenes in the control process as soon as the current flowing through the switch transistor threatens to become excessive.  This emergency control unit thus constitutes a predictive type of control that employs knowledge of the operation of the voltage control device and the instantaneous values of the input and output voltages of the voltage control device, in order to predict the voltage increase during the period interval (T).  Such an arrangement permits the emergency control unit to react very quickly.
