Title: Ultrasonic imaging apparatus
IPC: G01S15/89
Filed: 1975-08-11
Abstract: 1514475 Ultrasonic imaging devices; range measurement EMI Ltd 11 Aug 1975 [29 Aug 1974] 37744/74 Heading G1G An ultrasonic image converter is adapted to give a range reading of a selectable part of the image. As described a continuous wave emitted by an ultrasonic generator UG is reflected by an object O and focused by a lens system L on to the normally Piezo-electric target of an image converter tube ICT. The target is scanned by an electron beam in a raster format and a resulting electric signal is generated, amplified and used to modulate an electron beam of the cathode ray tube CRT arranged to scan in synchronism with the beam of the tube ICT by the timing mechanism TM. A point of the resultant image on CRT can be selected for range determination by using a brightened up horizontal and vertical line, i.e. an electronic cursor. The generator UG is then switched to emit a short pulse once in each full raster scan and the timing of the pulse is adjusted so that the received ultrasonic reflection coincides with the scan on the selected part of the image. When coincidence is attained, the selected part brightens up. The time difference between the reference timing of the electronic cursor and the timing of the transmitted pulse is directly related to the range of the object corresponding to the designated part of the image. Modifications (not shown) include using a light pen to replace the electronic cursor to provide the reference timing, using a brief interruption pulse in the continuous wave to result in a darkening of the selected image point on coincidence and using pulsed and continuous ultrasonic generation in alternate scan periods. The cathode ray tube CRT may be replaced by other suitable visual display means.

Abstract: 933,083. Fluid-pressure servomotor control systems. TEXACO DEVELOPMENT CORPORATION. Oct. 30, 1961, No. 38706/61. Class 135. In an electro-pneumatic control system comprising an electrical computer 95 feeding signals to an electromagnetically operated valve 11 which supplies a control signal to a controlled apparatus such as a relay valve 66 for a pneumatic controller governing a pneumatic valve 103, a reservoir 63 and an electromagnetically actuated valve 45 connected to the electric power supply to the computer are interposed between the valve 11 and the relay valve 66 whereby, on failure of the electric power supply the valve 45 is closed and the relay valve is maintained in the position it occupied at failure. The valve 11 has an output chamber 27 the pressure in which acts on a diaphragm 18 so that the pressure is related to the degree of energization of the electromagnet 16, excess pressure lifting a seat 25 from a valve rod 31 to vent the chamber through openings 26, 22 and insufficient pressure causing downward movement of the diaphragm to open a pressure supply valve 32. The relay valve 66 is similar to the valve 11 except that venting of the output chamber 78 takes place through an opening 72 between a pair of interconnected diaphragms 70, 71 so that the operating chamber 69 above the diaphragm assembly is sealed when the valve 45 is closed. The purpose of the reservoir 63 is to maintain pressure in the chamber 69 when the valve 45 is closed despite leakages in the system.
