Title: Compensating for depth in ultrasonic testing
Inventor: OPARA DR ULRICH
IPC: G01N29/04
Filed: 1983-11-28
Abstract: The depth compensation function 9 is made up of three component signals. The first component signal is derived from the AVG values for circular disc shaped equivalent reflectors stored in digital store 103 while the second component signal set by resistor 109 and ramp generator 110 takes into account the attenuation of sound in the material under test. The third component signal is derived from the differential values between the respective AVG values for circular disc shaped equivalent reflectors (Ao) and the corresponding values for the reflector (A INFINITY ) having no planar limits stored in digital store 104. Before the combination to form the depth compensation signal, these differential values are multiplied by an adjustable factor k 107 (see Fig. 3) for which -1</=k</=+1. Depending upon the choice of k, different depth compensation functions are obtained enabling correct depth compensation to be carried out when measuring flat or three-dimensional flaws and when measuring with sharply focusing test heads. <IMAGE>

Patent GB-2173580-A (GB)
Title: Apparatus for feeding steam/liquid into a steam generator
Inventor: CHIANG JAW-CHENG
IPC: F22D11/06
Filed: 1985-04-11
Abstract: A fluid feeding apparatus can gradually elevate the head of a fluid of steam/liquid mixture by recirculating the fluid through a centrifugal pump 2 of moderate output and an injector 3. The fluid ejecting out of the nozzle 31 of the injector 3 will entrain a steam/liquid mixture of high latent heat from a fluid intake port 33 so that the heat energy of the condensate from the other sources can be recovered and reused. By virtue of providing a gas intake port 34 for the injector 3, the fluid can be supplemented with gas wherever needed. Due to the substantial volume of the gas phase in the reservoir 1, the internal pressure of the reservoir 1 will not increase drastically because of the damping effect of the gas phase. Thus only a centrifugal pump 2 of moderate output is needed for implementing the recirculation of the elevation of the pressure in the reservoir 1. <IMAGE>

Title: Microprocessor controlled gas turbine aero engine and navigation system
Inventor: RITCHIE NORMAN STINSON
IPC: G05D1/00
Filed: 1986-08-08
Abstract: A microprocessor controlled gas turbine engine and navigational system, comprises a memory mapped visual display unit and monitor, operatively connected to a computer. The microprocessor computer unit has input means responsive to ambient air conditions, engine operating parameters, power control settings, and flight path navigational data. The microprocessor is preprogrammed to respond to the incoming signals, and compute output signals which adjust the engine operating variables in order to maintain the most efficient operation of the power unit, whilst displaying the position of the aircraft relative to the programmed definitive flightpath. The computer hardwire programme actively controls the engine settings to maintain steady state stoichiometric combustion within the flame tulips within the combustion chambers, and passively monitors temperature, pressure, and engine shaft speeds, flashing on the screen such information should such limits ever be exceeded. In order to prevent engine power degradation occuring under certain climatic conditions, the combustion process air is separated and filtered from the cooling air and an air-fuel proportional valve is used to ensure flame stability under all flight regimes. In addition the computer is responsive to ground generated three dimensional aircraft position data transmitted to the aeroplane from flightpath waypoints, airport radar installations, and navigational satellites, to provide flightpath correction or verification. Visual verification that the aeroplane is on the correct glideslope to the runway which may be provided by the airport instrument landing system, is supplied by an onboard infrared camera coupled to the visual display unit, and particularly useful where the airport has installed laser beams to replace landing lights during poor visibility.

Patent GB-2210169-A (GB)
Title: Apparatus for monitoring or measuring differential fluid presure
Inventor: GRAHAM PHILLIP
IPC: G01F1/38
Filed: 1987-09-21
Abstract: The apparatus monitors or measures differential pressures which arise for example across orifice plates or other components in pipes conveying natural gas or other compressible fluids, particularly in orifice flow meter applications. The effects on accuracy of spurious perturbations in the transducer lead lines, caused by pressure perturbations in the pipe 10, are eliminated or reduced by using two differential transducers 12, 14 communicating via acoustically equivalent paths 22, 24 with a common location at which a back-pressure P3 is sensed. Conveniently, the pressure P3 is sensed immediately downstream of an orifice plate 30, the transducers sensing pressures P1 and P2 at opposite sides of the plate 30. Additional but optional precaution against spurious perturbations in the lead lines is provided by damper material 36 and a reactive and/or dissipative filter 42. Alternatively, the transducer diaphragms 16 are mounted in the wall of the pipe 10; the material 36 and the filter 42 can be omitted. The transducers 12, 14 need not be matched. <IMAGE>
