Title: Data set backup in a shared environment
Inventor: STRICKLAND JIMMY PAUL
IPC: G06F11/14
Filed: 1995-05-24
Abstract: A method of taking a backup copy of a data set, for a log, with the data set being open for update by multiple updaters is described. A point on the log is identified (Recovery Time) from which it can be ensured that all data updates identified on the log have been written by an updater from buffers to the data set. This is done by recording a Recovery Time, and then not taking the backup until all the updaters have confirmed that they have written all updates from buffers to the data set. In addition, if tokens are used on the log to avoid having to identify the data set in full, then these are also written to the log before the update is taken.

Patent GB-2306197-A (GB)
Title: A pump control module
Inventor: STURMAN ODED EDDIE
IPC: F02M55/02
Filed: 1995-08-31
Abstract: A pump module that controls and varies the pressure of a fluid within a hydraulic system. The module includes a housing which has an inlet port, an outlet port and a return port. The inlet port is typically coupled to a pump. The return port is typically connected to a fluid reservoir. The outlet port is typically connected to a working device such as the fuel injector of an internal combustion engine. The module contains a spring loaded variable volume accumulator which maintains the fluid pressure at the outlet of the module. The module also has a three-way valve that provides fluid communication between the inlet port and the outlet port when in a first position, and fluid communication between the inlet port and the return port when in a second position. The module further includes a pressure transducer that senses the fluid pressure at the outlet port and provides a corresponding pressure feedback to an electronic controller. The electronic controller moves the three-way valve to the second position when the outlet fluid pressure exceeds a threshold value. Opening the valve allows the fluid provided by the pump to be directed to the reservoir through the return port, thereby bypassing the working device. Shorting the pump output to the reservoir reduces the work required by the pump. The fluid pressure within the system can be changed by varying the threshold value.

Title: A method of measuring fluid flow and fluid flow stability
Inventor: FRANKLIN BRYAN
IPC: G01F1/00
Filed: 1997-09-01
Abstract: A method of measuring fluid flow through a pipe including the steps of: (a) using a measuring device to take, over a period of known duration, a plurality of measurements indicative of the flow velocity at each of a number of locations distributed over a cross-section of the pipe, (b) averaging some at least of said plurality of measurements to provide averaged measurements, (c) utilising the averaged measurements to derive an evaluation of the distribution of flow velocity over the cross-section of the pipe, (d) deriving from at least some of said measurements of flow velocity an indication of the stability of the measured flow velocity, and (e) providing an indication, based upon said indication of stability, of the reliability of said evaluation. The method can be used to determine a profile factor with which the mean velocity of the fluid in the pipe as a whole can be calculated from a single measured point velocity, and is particularly applicable for use with installed pipework where the profile factor cannot be easily predicted.
