Abstract: A system includes an active node and a standby node and zero or more replica nodes. Each of the nodes includes a database system, such as an in-memory database system. Client updates applied to the active node are written through to the standby node, and the standby node writes the updates through to a primary database and updates the replica nodes. Commit ticket numbers tag entries in transaction logs and are used to facilitate recovery if either of the active node or the standby node fails. Updates applied to the primary database are autorefreshed to the active node and written through by the active node to the standby node which propagates the updates to the replica nodes. Bookmarks are used to track updated records of the primary database and are used to facilitate recovery if either of the active node or the standby node fails.

Abstract: Apparatus and method for quickly disconnecting a wetted parts subassembly from a paint spray gun wherein the wetted parts subassembly includes a spray tip, pump cylinder and piston and paint cup components including a pump housing cylinder support carrying the pump cylinder and having a pair of protrusions formed on a pump housing cylinder support, a frame having a pair of slots aligned to receive the protrusions when the pump housing cylinder support is received in the frame, a locking lever pivotably attached to the frame adjacent at least one of the slots and movable between a latched position wherein the pump housing cylinder support is retained to the frame, and an unlatched position wherein the pump housing cylinder support is removable from the frame. A passive retention feature frictionally engages the wetted parts subassembly with the frame when the wetted parts subassembly is received in the frame.

Abstract: A fully transactional mid-tier database system services database transactions. A cache manager dynamically loads database entries from a fully transactional backend-tier database system into the mid-tier database system according to the received database transactions. Time based aging or usage based aging can be assigned to selected tables in the mid-tier database system. Database entries contained in the selected tables are then automatically removed according to assigned aging constraints.

Abstract: Novel methods and structures are disclosed for making various cushioning structures especially useful for cushioning portions of the human body. Such cushioning structures can be used, for example, in footwear, chairs, beds, automobiles or other applications where improved human comfort is of interest. The spring structures in one embodiment comprise a plurality of spring assemblies arranged or integrally formed in compressible materials, such as compressible polymeric materials. The structures preferably are layered or graduated in contact surface area so as to provide variable deflection rates.

Abstract: Control of the gate electrode of a magnetic-beam-triode oscillator is effected by a diode connected between the gate and a controllable shunt regulator. The regulator is varied by a voltage derived from a differential amplifier forming part of a closed loop feedback circuit including the oscillator. By introducing an additional differential amplifier, variation of the regulator may also be made to depend on one of several parameters of the oscillator and load circuit, for example on the r.f. tank circuit voltage.
