Abstract: A downhole tool assembly has a sleeve with a continuous j-slot, a lug rotator ring configured to move axially relative to the sleeve and having a lug configured to move within the continuous j-slot, and a rupture disk configured to prevent the lug from moving within the continuous j-slot during run-in. A method of activating the downhole tool assembly includes lowering the downhole tool assembly into a well bore on a tool string, rupturing the rupture disk, allowing the lug to move within the continuous j-slot, and setting the downhole tool assembly by lifting upward and pushing downward on the tool string.

Another assembly provided herein includes a conduit adapted for installation in a well bore in a subterranean formation; one or more fluid jet forming nozzles disposed about the conduit; a fluid delivery tool disposed within the conduit, wherein the fluid delivery tool is operable to move along the conduit; a straddle assembly operable to substantially isolate the fluid delivery tool from an annulus formed between the fluid delivery tool and the conduit; and wherein the conduit comprises one or more permeable liners.

Abstract: Methods and devices useful in subterranean treatment operations are provided. One example of a device is a dart having a deformable body, a nosepiece connected to a lower terminus of the deformable body, and a channel extending through the deformable body and the nosepiece. One example of a method includes providing a dart, providing a production casing having at least one production sleeve therein, placing the dart in the production casing of a well bore, pumping a treatment fluid into the well bore, and allowing the dart to open the production sleeve within the production casing such that the treatment fluid is introduced into the subterranean formation through the production casing.

Abstract: A device includes a main body adapted to couple between a first element of a working string and a second element of the working string. A seal is provided about the main body and is adapted to substantially sealingly engage a wall of the wellbore. An conductor is carried by the main body. The conductor is adapted to communicate at least one of electrical current or a light signal between an interior of the first element and the second element while the seal is substantially sealingly engaging the wall of the wellbore, while the device is released from sealingly engaging the wall of the wellbore, and/or both.

Abstract: A computing system including a printer capable of retaining print jobs, a first computer and a second computer. The first computer is capable of transmitting a print job to the printer that causes the printer to retain the job. The first computer is also operable to cause the second computer to store a record of the job. A user of the first computer can later retrieve this record in order to identify the job. The user can also interact with the first computer to re-print the job.

Abstract: A locking slot assembly may include a slot, a lug configured to move within the slot, and a lock configured to prevent the lug from moving within the slot until a triggering event occurs. The lock may be further configured to allow the lug to move within the slot after the triggering event has occurred, so long as a predetermined condition is maintained. The triggering event may be the application of a predetermined pressure, and the predetermined condition may be a minimum pressure.

Abstract: A wellbore fluid treatment apparatus capable of being actuated by a sealing device. The apparatus includes a casing including a bore and a casing port opened through the wall of the casing. The apparatus also includes a sleeve located within the casing bore. The sleeve includes a sleeve port opened through the wall of the sleeve and a baffle seat forming an inner flow area and configured to receive the sealing device. The sleeve is moveable by the sealing device between a closed position preventing fluid flow from the bore through the casing port and an open position allowing fluid flow from the bore through the sleeve port and casing port. The apparatus also includes a reverse cement shoe attached to the casing. The reverse cement shoe has a valve that allows the casing to be cemented by displacing cement only on the outside of the casing.

Abstract: A computing system including a computer and a printer. The computer is operable to transmit a print job to the printer that cases the printer to retain the job. The computer is further operable to record a record of the job. The record includes an identifier of the job and an identifier of the printer. The user can later retrieve and display the job ID and request that the job be printed. The computer responds by causing the printer to print the job.

Abstract: A system for an interceptor client is utilized to improve the reliability of data transfer between devices on a network. In particular, the interceptor client may be configured to monitor transactions between a SNMP manager application and a SNMP application. The interceptor client may be further configured to monitor and to identify a “Get” command requesting multiple object identifiers (OIDs), e.g., OID.a, OID.b, . . . , OID.n, from a destination agent. The interceptor client may be further configured to preprocess the requested OIDs to the nearest possible previous OIDs, i.e., OID.a?1, OID.b?1, . . . , OID.n?1. The interceptor client may be further configured format the requested “Get” command as a “Get-Next” command requesting the modified OIDs from the destination agent. “Get-Next” command will always retrieve the next value in the tree of the MIB, regardless of whether or not a valid OID was specified.

Abstract: A method for establishing two-way communications between a host system and a device when the address of the device is initially unknown. The host system submits a job to a device with the job including address and other information required for the device to respond with the device's address. Once the host system has the device address, the host system and the device can establish bi-directional communications. In a print job, a print job language (PJL) command known as SOCKETPING is used to transmit the information between a print client and a printer. The SOCKETPING command includes fields for host system address family, protocol, address, and port as well as extensions to define job status reporting parameters. The printer responds to the SOCKETPING command with the necessary address information for the printer and job status reports as specified in the SOCKETPING extensions.

Abstract: A computing system including a first computer, a remote computer and a printer. The first computer is operable by a user to transmit a print job to the printer. The first computer is configured to automatically transmit a message to the remote computer. The message includes a copy of the print job. The remote computer is responsive to the message by storing the copy of the print job and by storing a record of the copy of the print job. A user can operate the first computer to retrieve and display this record. The user can also operate the first computer to cause the remote computer to transmit the copy of the print job to second printer.
