Abstract: Discussed is a process for preventing clathrate hydrate masses from detrimentally impeding the possible flow of a fluid susceptible to clathrate hydrate formation. The process is particularly useful in the natural gas and petroleum production, transportation and processing industry where gas hydrate formation can cause serious problems. Additives preferably contain one or more five member, six member and/or seven member cyclic chemical groupings. Additives include polymers having lactam rings. Additives can also contain polyelectrolytes that are believed to improve conformance of polymer additives through steric hinderance and/or charge repulsion. Additional additives include alkoxy compounds, and particularly those comprising ethoxy and or propoxy polymer blocks. Further additives include alcohols and oxazoline polymers which are preferably used in combination with polymers having lactam rings. Additives are useful in controlling clathrate hydrates in highly saline aqueous liquids.

Abstract: A scheduling system is disclosed for scheduling tasks for fulfilling a series of service requests. When each service request is received, a determination is made as to the amount of resources a task requires to provide the requested service. Further, a preferred time within which to perform the task is obtained from the requestor of the service request. For each service request, data for the estimated amount of resources and the preferred time are supplied, on a first-come-first-serve basis, to a scheduling component for solving a combinatorial optimization model which efficiently allocates a predetermined amount of resources for each time slot in a scheduling period by rearranging tasks for service requests previously received. The scheduling component provides for a service requestor, without regard to subsequently received service requests, a service time in which to perform the task for the requested service substantially immediately after the service request is made.

Abstract: A low-temperature refrigeration system (10) is disclosed for accurately maintaining an instrument (11) with a time varying heat output at a substantially constant predetermined cryogenic temperature. The refrigeration system (10) controls the temperature of the instrument (11) by accurately adjusting the pressure of coolant at a heat exchanger interface (12) associated with the instrument (11). The pressure and flow of coolant is adjusted through the use of one or two circulation loops and/or a non-mechanical flow regulator (24) including a heater (32). The refrigeration system further provides a thermal capacitor (16) which allows for variation of the cooling output of the system (10) relative to a cooling output provided by a cooling source (14).

Abstract: A sewing machine is provided for splicing together two different threads. The machine includes a thread tree with a number of thread spools with each thread thereof being inserted through flexible plastic tubing. A movable carriage assembly locates the new thread to be spliced relative to a splicing device passageway that receives the new thread to be spliced along with the old thread. The splicing device includes a front air inlet for drawing the new thread into the passageway of the splicing device and a rear air inlet for creating air turbulence during the splicing operation. Also used in moving the new thread through the passageway is an insertion drive roller connected to a pivotal rocker. A thread clamp cover connected to the rocker cooperates with the trimmer blades to trim the old thread. A thread clamp and a thread clamp magnet cooperate to hold the old thread in a desired position during the insertion of the new thread into the splicing device.

Abstract: A destaging method for a mapped data storage system is provided for writing data to a backing store. Data having non-sequential logical addresses are grouped together. The data includes data segments. A maximal difference in size between two data segments is less than a predetermined value. A constructed data segment includes a particular data item when the particular data item has a logical address between logical addresses of two other data items when they are part of this same constructed data segment. After being grouped together, such data is destaged from a cache memory to the backing store. Data from a group is transferred to an unallocated storage area of the backing store nearest to the physical position of the data transfer head responsible for the transfer. Each such transfer is continuous while reducing seek and/or latency delays and without regard to the nonsequential logical addresses of the data being transferred.

Abstract: A finite impulse response (FIR) filter and a Viterbi detector system for a magnetic read channel are disclosed. The FIR equalizer generates equalized sampled outputs to the Viterbi detector system. The Viterbi detector system determines the most probable value of all references, R.sub.i by accumulating a summation of data sample values, D.sub.t, for selected legal bit sequences over a significant amount of random data. The summation and count of data samples are output to a system microprocessor for calculation of an average reference for each path of the Viterbi system. The Viterbi detector system also calculates, in real time, magnitude of differences between the output data received from the FIR equalizer and transition references for each data sample to generate transition metrics, adds transition metrics to state metrics from the source node of two paths, and compares the result. The lesser of the two results yields the most likely correct state metric.

Abstract: In the system of the present invention, the system includes a pre-synchronizer to eliminate the need for examining every possible substring preceding the EOP (end of preamble) mark in order to detect the EOP. For the case where autocorrelation techniques are used to provide error synchronization error tolerance, this results in a much shorter EOP, since it is possible to find shorter EOPs which do not falsely synchronize prior to the arrival of the true EOP. In particular, the preamble is utilized to perform pre-synchronization. Once pre-synchronization has been achieved, the search for the EOP can be focused on a subset of all possible substrings as opposed to prior techniques which looked at all possible substrings. The resultant system solves the problem with less logic and more error tolerance.
