Patent EP-0328300-A2 (EP)
Inventor: GOSCENSKI EDWARD JOHN JR
IPC: F16H48/30
Filed: 1989-02-01
Abstract: A differential gear mechanism is provided of the type including a gear case (17), at least one pinion gear (21), and a pair of side gears (27 and 29). Clutch packs (43 and 45) are disposed between the side gears and the gear case and are operable, when engaged, to retard relative rotation between the gear case and the side gears. Surrounding the gear case is a fluid pressure mechanism (71) including a cylinder (73) and a piston (75), both of which are rotationally stationary, but free to move axially. Adjacent the piston-cylinder assembly is a pair of reaction members (61 and 63) which transmit the axial displacements of the piston and cylinder, by means of members (57 and 59), to a pair of load plates (53 and 55), such that the displacements exert axially-outward biasing forces on the side gears and on the clutch packs. Because the piston-cylinder assembly is external to the gear case, no rotating seals are required. In addition, because the hydraulic biasing forces act in the same direction as normal gear reaction forces, less hydraulic force is required to actuate the clutch packs.

Abstract: A message transfer arrangement includes a client node and a server node interconnected by a data link. The client node sequentially receives requests from user applications and generates, in response to each request, command messages for transmission by said interface, each command message including a command and having a transmit slot identifier identifying the request in the sequence of requests received by said request receiver and a transmit sequence identifier identifying the command message in the sequence of command messages relating to the request. The selection of whether to transmit a command message related to one request or to a subsequent request is based on a received slot identifier and a received sequence identifier in a response message. 
     The server node receives command messages from, and transmits response messages to, the client node over the data link. It selectively executes the command contained in each command message and generates, in response thereto, a response message including a response slot identifier and response sequence identifier corresponding to the command slot identifier and command sequence identifier. The determination of whether to execute a command in a command message is based on the command slot identifier and command sequence identifier of the received command message received by interface and the command slot identifier and command sequence identifier of the command message containing the previously executed command.

Abstract: One processor (20) of a multiprocessor or distributed system is designated as the owner of the shared storage. The remaining processors of the multiprocessor system are designated as requestor processors (10,30). The shared storage (60,70), typically several disk drive units, are connected to a storage controller (40). The storage controller is connected to all of the processors via a communications bus (80). 
The shared storage is dynamically segmented into containers of storage space (A1,...,A3M). A container can vary in size and even can be split up among more than one disk drive unit. A container located on one disk drive unit can also be duplicated, or mirrored, on a different disk drive unit. The owner processor maintains a container map (50) in its dedicated non-volatile storage. The container map contains fields that keep track of the physical location of a container, a use count, a key, and container attributes.
