Abstract: ABSTRACT OF THE DISCLOSURE         A cutting device, intended primarily for use in a confined space, e.g. for drilling apertures in a horizontally extending under-ground pipe exposed by an excavated shaft is provided herein.  The cut-ting device includes a jig for receiving a rotary cutting tool.  At least two expandable struts are connected to the jig and are arranged to be expanded laterally and outwardly from the jig to bear against an adjacent supporting surface or surfaces.  Means are provided which define an angle of inclination of the struts relative to an axis of rotation of the cut-ting tool, the angle of inclination being such that, when expanded against the surface or surfaces, each strut exerts on the jig a force having a component which is parallel to the axis of rotation and is directed towards a work surface, thereby clamping the jig against the work surface.          The cutting device is compact and can be positioned and operated from ground level.  It therefore requires only a comparatively narrow excavated shaft.

Abstract: METHOD FOR ESTABLISHING VARIABLE PATH GROUP ASSOCIATIONS AND AFFILIATIONS BETWEEN "NON-STATIC"         MP SYSTEMS AND SHARED DEVICES                Abstract of the Disclosure Multiprocessing systems having changeable CPU configurations generate unique changeable identifi-cations (ID's).  These are presented by I/O channels over various I/O connection paths, in association with special path defining commands and function data.  Related path state indications are stored peripherally in path map tables and define path group associations for sustaining path-independent I/O operations.  When a device is reserved via one path in a path group the reserve affiliation is extended automatically (in the path tables) to each path in the group, thereby rendering each path accessible in a reserved mode.  The path defining commands are used for adding paths to, resigning paths from and dis-banding groups.  Special sensing commands axe used for sensing path reservation and grouping states. When a command for adding or resigning a path is presented to a reserved device via one path in a group the reserve is automatically realigned to the enlarged or reduced group.  When a command for dis-banding a group is presented to a reserved device the reserve is realigned to apply only to the path on which the command is presented.  The foregoing special commands are required to be obeyed by the device even if it currently has a conflicting al-legiance to the same system or another system. Consequently, paths can be added to an established path group without requiring potentially premature release of any allegiance.

Abstract: ABSTRACT          The vertical conformance of a steam drive process is improved and steam override reduced by utilizing a solvent push-pull process in the lower portion of the formation adjacent the production well.          Steam is injected into the injection well with production of fluids from the production well.  The production well contains two flow paths from the surface, the first being in fluid communication with the upper portion of the Formation.  Production is continued until there is a water breakthrough from the formation via the first flow path in the production well.  After production via the production well is terminated, a predetermined amount of solvent is injected into the lower portion of the formation via the second flow path in the production well while continuing to inject steam into the injection well.  After the slug of solvent has been injected, production is immediately resumed by recovering fluids including solvent and oil from the formation via the second flow path in the production well until the amount of solvent in the produced fluid has decreased to a value less than 12 percent by volume.  The sequence of solvent injection followed by fluid production is continued for a plurality of cycles until there is water breakthrough at the production well.

Abstract: ABSTRACT A phase synchronizing circuit which has an extended pull-in range com-pared with the conventional phaselock loop is disclosed.  The conventional phaselock loop comprises a voltage controlled oscillator for generating an out-put signal in response to a control voltage, a phase comparator for phase-comparing the output signal from the voltage controlled oscillator with a first signal to provide a second signal, and a loop filter for smoothing the second signal to provide the control voltage.  In addition to these components the inventive circuit includes a phase shifter which phase-shifts the output signal by (.pi./2) + n.pi. (n being an integer) to provide a third signal.  A first mixer is provided for mixing the third signal with an input signal to provide a fourth signal.  A low-pass filter selects a low frequency component out of the fourth signal and provides a fifth signal whose phase is delayed in correspon-dence with the frequency difference between the input and output signals.  A second mixer is provided for mixing the fifth signal with the input signal to provide the first signal.
