Abstract: The present invention relates to an apparatus for keeping an electrical connection intact  within a pressurized well bore.  The electrical connection is made between a cable conductor extending from down hole of the well bore and a power conductor extending through and enclosed by a rigid tube extending through a wellhead barrier of the well.  The electrical connection includes a first connector terminating the power conductor and a second connector terminating the down hole cable conductor.  The second connector is mated with the first connector to complete the electrical connection.  Mated rubber boots surround the electrical connection.  The apparatus is comprised of a tubular top stop for fixedly attaching to the rigid tube including a hole for receiving the rigid tube therethrough.  The top stop engages and confines an upper end of the rubber boots.  A rigid tubular outer sleeve is provided for enclosing the rubber boots and has an upper end which engages the said top stop. A fastener is provided for attaching the top stop to the outer sleeve.  A tubular bottom stop is provided having a hole for receiving the down hole cable conductor therethrough.  The bottom stop engages and confines a lower end of the rubber boots.  A fastener is provided for attaching the outer sleeve to the bottom stop.

Title: Error prevention method for multimedia
Inventor: PARK DONG SEEK
IPC: H04L1/00
Filed: 1998-01-12
Abstract: An error prevention method for multimedia improves data recovery and channel throughput in channels which cause a random error and a burst error by using a rate compatible punctured convolutional code (RCPC) and an automatic retransmission on request (ARQ). In a process of decoding a plurality of packets of given information, the error prevention method includes the steps of a) decoding one of the plurality of packets, b) decoding another packet when an error occurs during the decoding in step a), c) decoding a combination of the packets from steps a) and b) or a third packet when an error occurs in step b), and d) repeating step c) until the decoding error no longer occurs.  The error prevention method has the characteristics of both Type-1 and Type-2 ARQ methods. Therefore, one can obtain constant channel throughput in the burst error containing channel, the random error containing channel, and a channel wherein the two error patterns coexist simultaneously.

IPC: C09K8/82
Filed: 1998-12-21
Abstract: Essence of invention: to create water isolation barrier in flushed highly permeable sections of the reservoir though injecting water solutions of two or more gel or sediment forming agents water solutions of the agents are injected into the reservoir in the form of blends (1:1 in volume) of a 50% aggregate stable water-in-oil emulsion in low viscosity hydrocarbon solvent (benzene, kerosene etc.) where prior to this 5-20 mass % of concentrated porphirine and asphaltene-resin oil components are dissolved (i.e. OPA agent prepared as per TU -24358-001-21166006-97). Dispersion of the resulting water-in-oil emulsion (dimensions of stabilized water droplets in "oil") should be comparable to the dimensions of flushed highly permeable sections of the reservoir. For the chemical reaction of injected gel or sediment forming agents to take place after the injection of blended 50% aggregate stable water-in-oil emulsion into highly permeable sections of the formation, its concentration in these sections, a hydrocarbon solution of water-in-oil emulsions demulsifier is injected in the reservoir. Concentrated water-in-oil emulsion is destroyed, water solutions of gel and sediment forming agents are formed and blended and chemical reaction of these agents tales place in highly permeable section of the reservoir resulting in a water isolation barrier (cross linking polymer composition or insoluble in water sediment). The present invention allows to increase effectiveness of treatment considerably through water solutions of two or more gel or sediment forming agents due to avoiding premature chemical reaction of applied agents and their adsorption in reservoir conditions.

Abstract: The ATV LOCKER is a fastening and locking system for ATV's.    Quads and trikes can be very difficult to restrain on a vehicle, especially when driving on rough terrain, and can be stolen by being lifted, pushed, or pulled off of a vehicle. 1n the described embodiment, the ATV LOCKER accommodates most quads and trikes which are easily secured by pins or padlocks once the locking bar on the ATV LOCKER is placed into position on the quad. Thus the ATV's are virtually impossible to remove giving you the advantage over thieves. Bolting the ATV LOCKER down to the truck bed or trailer floor makes the quad become part of the transport vehicle, making it much more secure. To add for greater stability when transporting the ATV, a piece of chain with hooks is pinned to each outer edge of the ATV LOCKER, this is to hook to the foot pegs on the ATV for example, this will eliminate side motion when traveling.
