Patent CA-2010152-A1 (CA)
Title: Systolic array processing apparatus
Inventor: HELBIG WALTER A SR
IPC: G01S3/28
Filed: 1990-02-15
Abstract: SYSTOLIC ARRAY PROCESSING APPARATUS               Abstract of the Disclosure A rectangular antenna array includes a plurality of systolic vertical line arrays.  Each vertical line array includes a plurality of signal processors.  Within each line array, the signals received at any one moment are held or delayed as required, and the processors progressively form partial sums in an upward direction during first clock intervals and in a downward direction during alternate clock intervals.  During each clock intervals, complete sums for one sample interval appear at an end of the vertical line array.  The sums appear alternately at the top and the bottom of the line arrays.  Beamforming in the horizontal direction is accomplished with systolic horizontal adders coupled to the tops and bottoms of the vertical line arrays.  The horizontal adders transfer information and add in one direction during first clock intervals, and then in the other direction during third clock intervals of a four-interval cycle.  In a particular embodiment of the invention, multiple inputs and outputs associated with each processor allows continued operation in the event of partial or complete failure of one or more processors.

Title: Method and apparatus for photoinductive imaging
Inventor: MOULDER JOHN C
IPC: G01N25/72
Filed: 1990-07-19
Abstract: ABSTRACT OF THE DISCLOSURE     A system for photoinductive imaging for flaw detection of materials and for calibrating eddy current probes includes positioning an eddy-current probe adjacent to a specimen to be analyzed or to be used as a calibration fixture.  A source of thermal energy is modulated and focused to a localized area on the specimen.  Thermal energy is then scanned across at least a portion of the detection area of the eddy-probe.  The resulting signal from the eddy-current probe is recorded and can depict either thermal-influenced components of the specimen or the response pattern of the eddy-current probe.  The record can therefore be used to image flaws or physical holes or shapes of the specimen or calibrate the eddy-current probe.

Title: Microinstruction sequencer
Inventor: HORST ROBERT W
IPC: G06F9/26
Filed: 1990-11-21
Abstract: MICROINSTRUCTION SEQUENCER                   ABSTRACT OF THE DISCLOSURE         First and second banks of control stores are used to store microinstructions.  Each tank contains three control stores:  A horizontal control store, a vertical control store, and a jump control store.  The horizontal control store contains the rank four microcode; the vertical control store contains the rank three microcode; and the jump control store contains the same microcode as the vertical control store but is used on conditional jump microoperations.  In one embodiment of the invention, the contents of the vertical control store are logically offset from their original address by 1 whereas the contents of the horizontal control store and the jump control store are aligned with their original address.  In another embodiment, the contents of the horizontal control store and the jump control store are offset from their original addresses by one, whereas the contents of the vertical control store are aligned with their original addresses.  This allows simultaneous accessing of different microinstructions using a single address counter.  The control store banks are accessed in an overlapping manner so that upon each clock cycle one bank is loading the rank 3 and rank 4 registers.          The contents of the two banks are the same to provide soft error coverage and recovery.         The sequencer according to the present invention includes a return address stack for returning from subroutine calls and trap routines.  When processing trap routines, the return address stack stores two microinstruction addresses to allow processing of a previously encountered jump or call operation that may have been aborted when the trap routine was entered.

Title: Process for the conversion of light olefins to ether-rich gasoline
Inventor: MIZRAHI SADI
IPC: C10G57/02
Filed: 1991-03-27
Abstract: PROCESS FOR THE CONVERSION OF LIGHT OLEFINS TO        ETHER-RICH GASOLINE                     ABSTRACT      Light olefins are converted to gasoline with a high enough content of ethers to provide a significant octane improvement over a base ('or cracking') gasoline (clear RON = 90-92; clear MON = 79-80).  One portion of the olefins is hydrated to produce alcohols, and the other is used to synthesize an olefin-rich gasoline. The alcohols are used to etherify the gasoline.  The combination of unit operations minimizes the energy needed to run the process for which no external solvent is needed.  The process capitalizes on the higher solubility in gasoline of ethanol, propanol, and butanol, compared to methanol.  Besides having very low solubility in gasoline, etherification with methanol or ethanol produces an inadequately rewarding increase in octane number, compared to propanol or isopropanol. Taking advantage of the inherent chemical and physical properties of C3-C4 alcohol/gasoline mixtures results both in an unexpectedly high octane number for the ether-rich gasoline as well as an effective and economical process for producing it.  The improvement in octane is particularly noteworthy because the weight percent of oxygen in olefinic gasoline etherified with C3-C4 alcohols is less than one-half that of gasoline etherified with either C1 or C2 alcohol.
Patent CA-2040281-A1 (CA)
Inventor: JORDAN JOHN WESLEY
IPC: E21B43/119
Filed: 1991-04-11
Abstract: A perforating gun assembly is set forth. It incorporates a swivel connected with a cable head assembly and a navigation system for determining the instantaneous angle of the tool with respect to a vertical reference. There are first and second spaced cages formed of sleeves supported on bearing assemblies. The sleeves support free wheeling rollers which engage the casing when the tool is in the slant hole region of the well. There is an eccentric which falls downwardly, i.e., pointing toward gravity, and thereby defines a vertical reference and hence a horizontal reference. This eccentric mounts an elongate tubular housing for the shaped charges. Initially, the angle of firing of the shaped charges is adjusted at the time of installation with respect to the horizon and that in turn is correlated to the formation of interest in the well borehole which is then perforated with perforations which are parallel to the formation bedding plane.

Title: Double hoist drive using load coupled hold and close variable frequency motors
Inventor: JAMES MICHAEL
IPC: B66C3/12
Filed: 1991-08-14
Abstract: A hoist drive for a double hoist carrying member having a hold hoist drum, a hold rope connected to the hold hoist drum and from which the carrying member is suspended, and a hold motor for rotating the hold hoist drum to raise and lower the carrying member.  The hoist drive further includes a close hoist drum, a close rope connected to the close hoist drum and from which the carrying member is suspended, and a close motor for rotating the close hoist drum to raise and lower the carrying member.  During raising of the carrying member, the hold and close motors are each supplied with a.c. power at different preselected frequencies.  The hold and close motors each operate along a first pair of intersecting frequency to torque curves during a raising operation in which the hold motor curve is steeper than the close motor curve.  During a lowering operation the hold and close motors operate along a second pair of intersecting frequency to torque curves in which the hold motor curve is also steeper than the close motor curve.  Due to the intersection and relative slopes of the first pair and the second pair of curves, the speed of the hold motor follows the speed of the close motor during both raising and lowering operation and the motors operate at the intersection points of the pairs of curves and share the load during both raising and lowering operation.
