Abstract: HIGH VERTICAL CONFORMANCE STEAM DRIVE OIL RECOVERY METHOD       (D#76,018-1-F) ABSTRACT OF THE DISCLOSURE         The vertical conformance of a steam drive process is improved and steam override reduced by penetrating the zone between one injector and one producer, with an infill well located between the injector and producer which is in fluid communication with no more than the bottom half of the formation.  Steam is injected into the injection well in the first phase with production of fluids from the upper 1/3 or less of the formation via the production well.  A separate flow path in communication with the bottom 1/3 or less of the formation is provided in the producing well,  and is used during the  first phase for push-pull treatment of the formation with solvent and steam or hot water.  After production via the production well is terminated, petroleum is produced via the infill well until the fluid being produced from the infill well reaches 95 percent water cut, after which the infill well is converted from a producer to an injector and hot water is injected into the lower portion of the formation via the infill well and fluids are produced from the production well.  After water breakthrough at the production well, steam is injected into the infill well and fluids are recovered from the lower 1/3 of the production well.                             -I-

Abstract: Abstract This invention relates to an improved method and apparatus for detecting the level of a first fluid. It includes a reservoir within the first fluid, the reservoir being bounded by a flexible membrane at its lower portion for containing a second fluid.  The reservoir contains at least one switching means biased to assume a first position when the second fluid is be-low a predetermined level and adapted to assume a second position upon the rising of the first fluid into pressure exerting contact with the flexible membrane.  The rising first fluid compresses the lower flexible membrane portion of the reservoir and causes the second fluid within the reservoir to also rise thereby causing the switching means to assume the second position.

Abstract: ABSTRACT OF THE DISCLOSURE      A routing machine for routing a non-linear groove in a flat extensive workpiece having a pattern in the form of a curved rib temporarily secured to the underside thereof.  A reference roller in alignment with the routing tool engages a reference surface on the pattern while a cooperating roller is biased against the opposite surface, the rollers being driven so that the pattern is advanced to move the workpiece relative to the tool.  The cooperating roller is mounted upon a table which is freely rotatable about the axis of the reference roller so that when the rollers encounter a portion of the pattern which changes direction, the cooperating roller is free to change its orientation with respect to the reference roller thereby enabling the workpiece to retain its initial orientation regardless of changes in direction taken by the pattern.          Both of the rollers are positively driven at the same peripheral speed but one of the rollers is smoothly surfaced for casual slippage with respect to the pattern in regions where the pattern changes direction.  The cooperating roller is driven by a gear train which is mounted upon the table and which has an initial gear which is arranged coaxially with respect to the table.

Abstract: "DISTRIBUTED NETWORK SYNCHRONIZATION SYSTEM" ABSTRACT OF THE DISCLOSURE          A synchronization system is provided for a tree-type transmission system comprising a central station connected to a plurality of remote stations in an effectively sequen-tial manner, each station including transmitting and receiv-ing means for digital data in a sequence of frames.  Each remote station is instructed regularly by the central station of the time delay between the remote station and the central station.  The remote station stores the time delay and arranges to advance information transmitted by the remote station so as to be received by the central station within the proper position in the frame.  The time delay is measured by the central station by sensing a pattern of bits repeti-tively transmitted by the remote station and comparing the received pattern with a stored pattern and counting the num-ber of shifts of the received pattern necessary to match the stored pattern.  The delay stored by the remote station is tuned to one quarter of a bit to ensure accurate synchron-ization.

The container is constructed of light weight strong, durable material to protect its contents and is capable of being hand carried, shoulder slung, pulled on casters on the ground or as a toboggan on the snow, built in fittings included for car top transport singly or in plurality, as well as a nesting feature for stacking a plurality of containers on public transportation systems such as buses, trains, and aeroplanes.  Protection of the very expensive ski equipment is also provided against the environment such as road salt and grime, and theft.  Out of season storage of all ski equipment is provided and centralized in this container.  Alternative uses are unlimited covering such things as hunting, fishing, scuba diving, hockey, camping, tools, or whatever items fit into the container.  As the title implies, it is a universal carrier for any items that will fit within. Primarily it was designed to fit the needs of those skiers travelling relatively long distances by auto, bus or aeroplane with numerous items such as skiis strapped together or in a bag, poles, boots, hand luggage with clothes, cosmetic case and the like, all to be coped with at the check-in and check-out counters of the transportation terminals, whereas this confusion, awkwardness, and in some cases grief and inability to manage everything is eliminated by this invention where everything is contained in one container which adapts to any mode of transportation.
