摘要： A method of synchronization for use in a distributed data processing system comprising a legacy computer having means for storing a master version of data, an application server, and a thin client computer which stores a copy of the master version of data. Firstly, the thin client executes operations locally on the copy. The operations are sent in a list to the application server. The application server executes the operations on the master data, on behalf of the thin client. If the operations can be executed successfully on the master version, synchronization occurs in that the successful operations are applied to the master version.

摘要： A power chain saw oiling device that automatically supplies lubricating oil to the cutting chain and guiding cutting bar. The device is easy and economical to fabricate and to assemble in the saw. An oil reservoir is formed in the saw housing and an oil flow path leads from the reservoir through a piston type pump to an oil distribution cavity open to the cutting bar and chain. The piston is operated directly by sliding contact against a cam rotated with the output shaft. A bypass tube of relatively narrow cross section is provided from the pump output chamber and discharges into the oil reservoir from its discharge end which is located above the distribution cavity to the cutting bar and chain. Oil flow from the pump is thus directed both to the oil distribution cavity for chain lubrication and to the bypass tube back to the oil reservoir. Under normal saw operation oil flow occurs to both, with sufficient discharge occurring to the chain for proper lubrication thereof; whereas the uphill pitch of the bypass tube creates a back pressure so that under low speed saw operation most, if not all, of the oil flow effectively goes to lubricate the chain and little or no oil is bypassed to the oil reservoir.
