  • Publication number: 20050102582
    Abstract: A host data processing system includes a data storage system having a cache memory and a back end storage. In response to a detection of an event failure during an input/output (I/O) request from the host data processing system to the data storage system, the data associated with the I/O request is forwarded to the back end storage data, and a copy of the data associated with the I/O request is sent to the cache memory. A determination is made as to whether or not there is an acknowledgement from the back end storage regarding the receipt of the data associated with the I/O request. If there is an acknowledgement from the back end storage regarding the receipt of the data associated with the I/O request, the data associated with the I/O request is flushed from the cache memory, and the received acknowledgement is routed to the host data processing system.

  • Patent number: 6439439
    Abstract: A bone cement delivery apparatus is provided which includes a body, a ram, a trigger mechanism, and a pawl assembly. The body is configured to support a bone cement dispensing container. The ram is carried by the body and is configured to advance relative to the body to urge bone cement from the dispensing container. The trigger mechanism is located on the body and is configured for actuation to advance the ram. The pawl assembly is carried by the trigger mechanism to engage the ram, the pawl assembly comprising a pawl is carried by the trigger mechanism infinitely adjustable in relation with the trigger mechanism between a relatively low force position and a relatively high force position.

  • Patent number: 6058611
    Abstract: A knife is described including a handle with a blade mount. An elongated blade with a handle mounting surface is releasably engageable with the blade mount on the handle to enable selective attachment and detachment of the blade to and from the handle. The blade mount includes a blade back configured to receive a length of the blade and a tang disposed within the handle. A blade release is formed integrally with the tang and includes an integral elongated bar spring extending longitudinally within the handle from an end joined integrally with the tang, to a laterally movable free end. A blade lock is located on the elongated bar spring adjacent the movable free end, laterally positionable by deflection of the elongated bar spring to selectively engage and lock the blade in an extended operative position, and a release position clear of the blade.

  • Patent number: 3971271
    Abstract: A wrench for surgical use including a housing having an extension at the end of which there is a socket member having a slot through the wheel thereof with the socket member aligned with the corresponding slot in the free end of the extension to permit a nut on an extremely threaded rod to pass into the socket. The socket is peripherally toothed for engagement by a pair of worm gears disposed at respective sides of the socket member so that there is always driving engagement between the worm gears and socket member for rotating the socket member. Crank operated gears are exposed in the housing and are connected by drive shafts of the worm gears.A slidable nut retainer is disposed at each side of the extension and each is provided with a notch for reception of the threaded rod; the parts of the slidable nut retainer at the side of the notches, overlap the nut to prevent it from coming out of the socket.
