  • Well casing perforator
    Patent number: 7740059
    Abstract: A well casing perforator for efficiently recovering available water in a previously drilled well by perforating the well casing. The well casing perforator generally includes a frame adapted to be inserted within a well casing and move in a direction parallel to a central longitudinal axis of the well casing, at least one perforator pivotally connected to the frame and including a plurality of spikes extending therefrom for engagement with the well casing and at least one spring to impart a bias force upon the perforator so that the spikes automatically grab the well casing and rotate through the well casing with a change in directional movement of the frame.

  • PUMP DISPENSERS
    Publication number: 20100096412
    Abstract: Certain pump dispensers, for example foam dispensers, are specially adapted for inverted use. One feature especially useful in a foam dispenser having both an air cylinder and a liquid cylinder with respective pistons is an intake conduit arrangement to increase the clearance of liquid from the container. An intermediate shell fits over the upright liquid cylinder body and carries an inlet valve positively urged upward to the closed position to prevent leaking. A conduit shell fits over the intermediate shell and creates an intake conduit extending down the side of the liquid cylinder to an intake opening lower down the pump body.

  • AIRLESS DISPENSING PUMP
    Publication number: 20100089945
    Abstract: An airless dispenser pump assembly includes a pump mechanism with an inlet valve that is configured to efficiently pump viscous fluids and that is able to be pre-primed when the pump mechanism is attached to a container. In one form, the inlet valve includes a seal member that seals an inlet port of the pump and an outer support member that secures the inlet valve to the rest of the pump mechanism. Two or more legs generally extend in a circumferential direction between the support member and the seal member in order to create a large flow opening for fluid flow through the inlet valve when opened and to rapidly close the inlet valve. The pump mechanism further includes an outlet valve that is configured to draw fluid back from a nozzle of the pump after dispensing in order to minimize build up around the nozzle.

  • SYSTEM AND PROGRAM PRODUCT FOR REPLICATING MESSAGE STATUS CHANGES ACROSS MESSAGING SYSTEMS
    Publication number: 20090063644
    Abstract: The present invention provides a method, system and program product for replicating message status changes across messaging systems. Specifically, under the present invention, when a status of a message for a user is changed on a messaging system, the status change is entered into a log associated with the user along with a clock time of the messaging system. The status change is then replicated to a replica messaging system along with the clock time of the original messaging system. Upon receipt, the replica messaging system will ensure that the status change is the most recent activity for the message. If so, the status change will be entered into a log of the replica messaging system along with the clock time of the original messaging system and a clock time of the replica messaging system.

  • Method and system for dynamic queue splitting for maximizing throughput of queue based operations while maintaining per-destination order of operations
    Patent number: 7493428
    Abstract: A system for providing dynamic queue splitting to maximize throughput of queue entry processing while maintaining the order of queued operations on a per-destination basis. Multiple queues are dynamically created by splitting heavily loaded queues in two. As queues become dormant, they are re-combined. Queue splitting is initiated in response to a trigger condition, such as a queue exceeding a threshold length. When multiple queues are used, the queue in which to place a given operation is determined based on the destination for that operation. Each queue in the queue tree created by the disclosed system can store entries containing operations for multiple destinations, but the operations for a given destination are all always stored within the same queue. The queue into which an operation is to be stored may be determined as a function of the name of the operation destination.

  • Unread mark replication bounce-back prevention
    Patent number: 7475095
    Abstract: Under the present invention, a method, system, and program product for preventing an unread activity from being sent back (i.e., bounced-back) to its originating server during a replication operation are provided. The method includes: storing an identification of an originating server of a replicated unread activity, the unread activity being associated with a read/unread status of an email, in an unread log of a receiving server; during a subsequent replication process initiated by the receiving server, preventing replication of the unread activity back to the originating server; during the subsequent replication process, replicating the unread activity to at least one other server; and storing the identification of the originating server with the unread entry.
