Abstract: IMPROVED PROCESS FOR RECOVERY OF BITUMEN         FROM A BITUMINOUS FROTH            Abstract of the Disclosure An improved method for recovery of bitumen from bituminous froth is disclosed having particular application in hot water separation of tar sands wherein comminuted tar sand is slurried in hot water, subject to gravity separation to isolate a bituminous froth, containing water and mineral matter, and the bituminous froth is diluted with a liquid hydro-carbon solvent and subject to a two-stage centrifugation to recover  the substantially water and mineral-free bitumen.  In this improved process, the dilution of bituminous froth with liquid hydrocarbon solvent is staged such that no more than about 90% of the total hydrocarbon solvent is added to the bituminous froth prior to the first centrifuging stage and the remaining hydrocarbon solvent is added prior to the second centrifuging stage.

Abstract: METHOD AND APPARATUS FOR CONTROLLED GENERATION OF WALL TOPOLOGY IN MAGNETIC DOMAINS            ABSTRACT OF THE DISCLOSURE      Magnetic domains with defined wall topologies are con-trollably generated from a domain having known characteristics A "mother" bubble domain of a known wall state is generated by nucleation.  The mother domain is stretched and split in the presence of a magnetic field directed across the separation area.  A pair of Bloch lines is generated in every splitting process.  The assignment of the lines to either one or the two resulting domains depending upon the wall state of its mother domain and the direction of the directed magnetic field. In-stead of the directed magnetic field, velocity inducing forces can be applied to the elongated domain.  The effect desired is to incline the wall magnetization in the elongated section of the domain.  Controlled resplitting of domains having Bloch lines increases the number of Bloch lines in one domain to generate any predesignated wall state.  The multiplicity of states which can be controllably generated anticipates their utilization beyond binary bit coding.

Abstract: APPLICATION OF:  GEORGE R. PIPES                         FOR:  SHUTTLE ASSEMBLY FOR A LOAD       HANDLING APPARATUS            A B S T R A C T     An improved shuttle assembly for use on a load handling apparatus, the shuttle being of the type which moves between a retracted position and an extended position.  The shuttle assembly has a base plate which remains stationary and includes a gear train in driving engagement with a rack on the underside of a driver plate to move the driver plate longitudi-nally relative to the base plate.  The driver plate includes at least one gear which rotates in a normally horizontal plane and engages a rack which remains fixed relative to the base plate, so that the gear rotates in response to longitudinal movement of the driver plate.  Adjacent the periphery of the gear is a roller or a cam follower which drivingly engages a channel attached to the underside of an intermediate member, thus causing the intermediate member to move relative to the driver plate at a velocity which is generally sinusoidal.  A load supporting top plate is driven at a sinusoidal velocity twice that of the intermediate member by means of a chain drive having one end attached to the base plate, the other end attached to the top plate, and passing around a sprocket attached to the intermediate member.  The load supporting top plate is therefore able to move between the retracted position and the extended position at a substantially greater average velocity, requiring only a simple, one-speed input, and the preferred sinusoidal velocity improves the load control capability because the load moves slowly at the beginning and end of the travel.

Abstract: ABSTRACT OF THE DISCLOSURE A method of making a connection to protect a shore approach section of an underwater pipeline comprises drilling a hole downwardly through the sea bed, introducing a sealed pipe riser, which may, or may not, have an elbow welded to the upper end thereof, into the hole; grouting the inserted pipe riser in the hole and connecting a tunnel section to the shore with the pipe riser.  A pipe is passed through the tunnel and joined to the pipe riser.  The tunnel pipe may be connected to the pipe riser after the drilling of the hole by the completion of the tunnel to intersect the pipe riser or, in the alternative, the tunnel section may be completed first and have the leading end thereof sealed off by a bulkhead, whereafter the hole is drilled to intersect the tunnel at the sealed off tunnel end and the connection of tunnel pipe and pipe riser is accomplished by dewatering the leading end of the tunnel and opening the bulkhead.  The method is particularly useful in ice covered water crossings and here the drilling of the hole is accomplished using the ice surface as a support platform for the drilling rig.

The stripping gauge comprises a marking molded on the device and indicating the length of insulation to be re-moved from the wire prior to forming the loop in the bare end of the wire. The loop-forming gauge comprises side walls de-fining a cavity in the body of the device and a rounded shoulder formed at an upper end of said cavity.  The bare end of the wire is confined within the cavity while the bare end of the wire is bent over the rounded shoulder into the form of the loop in the wire.  The wiring device also includes wire-restraints which engage with insulation on the wire when the loop is secured under the binding screw.          The method disclosed involves measuring and stripping insulation from the end of an insulated conductor wire.  Then bending the stripped bare end of the wire into a loop at a location where insulation on the wire extends into the wire-restraint when the loop is secured under a binding screw carried by a terminal plate.
