Title: Hydraulic valves
Inventor: KADLICKO GEORGE
IPC: F15B13/04
Filed: 1995-02-06
Abstract: A hydraulic valve (10) includes a spool (40) movable within a body (12) to regulate flow across the valve (10). Movement of the spool (40) is controlled by an electromagnetic actuator (78) that operates either directly or through a pilot stage upon the spool (40). When operating through a pilot stage, the actuator varies pilot pressure by an operating member co-operating with an orifice. A flapper valve (129) may be used to vary a pair of pilot flows in complementary manner. Feedback signals of pressure and spool position are provided to a controller which selectively combines the signals to monitor the operating parameters of the valve. The controller may modify the position signal with the pressure signal to obtain an indication of flow rate through the valve (10).
Patent GB-964103-A (GB)
Abstract: 964, 103. Timing machine operations. J.A.M. TAYLOR. Aug. 4, 1960 [Dec. 1, 1959], No. 40780/59. Heading G1J. [Also in Division G4] apparatus for measuring bonus time increments comprises timers TA, TB set to measure a required time interval which is compared with the time interval between two operation signals, the difference being indicated by a register MSE. The timers TA, TB are both set for the time period allowed for a particular job. At the beginning of the first job the operative closes a switch S1 manually or it is closed automatically by the machine he is operating. The timer TA starts and a relay A/3 operates closing its holding circuit at A1, preparing a bonus gained circuit at A2 and opening a bonus lost circuit at A3. At the end of the period allowed for the job the timer .TA is reset and opens contacts TA1 to release the relay A/3. At the beginning of the next job a switch S2 is closed, timer TB starts and relay B/3 operates in the same way as relay A/3 before. Thus if the second job begins before the timer TA runs out the bonus gained circuit is completed and a motor FM drives the register MSE in one direction to indicate the time gained but if the timer TA runs out before the second job is begun the bonus lost circuit is completed and a motor RM drives the register MSE in the opposite direction. The switches S1, S2 are operated alternately either manually or automatically by the machine. Individual job bonus times may be registered successively by one pointer 1 and the net bonus time over a succession of jobs (may be) registered (accumulatively by the other). Indicator lights or audible indicators IF and IR may be connected across the motors FM and RM to advise the operator whether he is gaining or losing bonus. Counters may be arranged to count the odd and even numbered jobs and another counter may register the number of times switch S1, S2 is operated to check that it is. operated only once for each job. The bonus times indicated by the register MSE may be recorded on a tape or chart.

Title: Behind casing wellbore logging
Inventor: PRIEST JOHN FINLEY
IPC: G01V1/50
Filed: 1997-06-06
Abstract: Logging a subterranean formation 16 from within a well 2 that has been cased and cemented. An acoustic signal 12 is transmitted into the formation from a pulse-echo transducer 10 placed within the wellbore, and the first casing echo 15 (fig. 3a) and first formation echo 115 (fig. 3f) are detected. The amplitude and arrival times of these two echoes are used to determine the casing inner radius and thickness, the concrete thickness and the formation reflectance amplitude. The casing thickness may be computed using a resonance method. Given the attenuation in the wellbore fluid and fill material, and the impedance of the wellbore fluid, casing and fill material, the formation reflectance amplitude is corrected to replicate the amplitude that would otherwise be expected in a wellbore without casing. The formation behind the casing can thus be imaged.

Title: An authentication system using magnetic markers with a feedback system to control the magnetic reader field
Inventor: ROSEMAN MORTON FRAZER
IPC: G08B13/24
Filed: 1999-01-15
Abstract: A marker containing a magnetic material is attached to an item to be authenticated or authorized. A reader is provided containing a transmitter 10 which generates a varying electromagnetic search field 5 and energises the magnetic material when the marker is present. A receiver section 13, 15, 16 analyses the signal produced by the resulting interaction and gives an authentication decision based upon a match with stored information. The reader employs a feedback control system (46) to stabilize the magnetic field generated. The receiving antenna has loops whereby, when placed in a field with no marker present, the signals in the loops cancel each other. However, if a marker is present in the field, the spatial distribution of flux is changed and a differential signal is generated in the receiving antenna. All the markers have substantially the same magnetic properties and so generate the same signal. The markers can be used to differentiate real products from counterfeit ones.
