Title: Acoustical holography system for acoustic image conversion
IPC: G01H9/00
Filed: 1972-05-26
Abstract: 1385265 Acoustic holography THOMSON CSF 26 May 1972 [28 May 1971 27 Aug 1971] 25094/72 Heading H4D [Also in Division G2] In an acoustic holography system the ultrasonic energy transmitter is operated intermittently in producing the hologram at a fluid surface, and an optical chopper is used to limit the operation of an image-reconstructing device to those times when the hologram exists. In the Fig. 1 embodiment transducers 10 and 4 are energized by pulse generator 18 to provide respectively an ultrasonic reference beam and an ultrasonic beam modified by an object 1 immersed in the fluid. These beams interfere and form a surface-relief hologram 17 in an oil film 14 supported by a polycarbonate membrane 16. An image of the object is reconstructed by directing light from a laser 250 via a chopper (modulator) 23, lens 25, diaphragm 26, mirror 30 and lens 28 on to the hologram, whereby diffracted light is focused by lens 28 on to an aperture 31 which passes a first order diffraction pattern for recording on a photographic plate or for displaying using a vidicon tube 32 feeding a cathode-ray tube display 34. To ensure illumination of the oil film 14 at the instant ultrasonic pulses reach it, the chopper 23 and generator 18 operations are synchronized either by (a) a rotary electrical switch driven by the chopper and used for triggering generator 18 (Fig. 2, not shown), (b) an ultrasonic receiving transducer near oil film 14 for detecting the pulses and operating the chopper (Fig. 4, not shown), or (c) an electrical delay line receiving an output from generator 18 and providing delayed signals for operating the chopper (Fig. 3, not shown). The use of the chopper prevents undesired light flux from passing through aperture 31 during the times when no hologram exists at the oil film 14. For optimum image reconstruction, the transducers 4, 10 are arranged to provide plane or spherical wave-fronts and acoustic mirrors 6, 7 and 8 form an acoustic image of object 1 in or near the plane of the hologram. Mirrors 7 and 8 may be movable to select a cross-sectional plane of object 1 which is to be acoustically imaged in the hologram plane.

Title: Improvements in or relating to methods and apparatus for monitoring electric signals
Inventor: CLARK HENRY ARTHUR MAISH
IPC: G11B5/00
Filed: 1954-09-01
Abstract: 780,267. Magnetic recording and reproducing apparatus. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Aug. 11, 1955 [Sept. 1, 1954], No. 25351/54. Class 40 (2). [Also in Group XXXIX] In a method of producing magnetic records copied from a master recording the signals from the master recording are fed to a plurality of similar re-recording machines to produce copy records, the similar re-recorded signals are reproduced from the copy records with similar time delays, a reference signal related to the average of the similar signals is derived from the similar signals and is compared with one or more of the similar signals, an alarm signal being given when the compared signals differ substantially. As shown, the reproducing heads 1 of the five re-recording machines feed individual amplifiers 2 the outputs of which are rectified by rectifiers 3 each giving an output proportional to. either the average or the peak value of the waveform fed to it. The rectified signals are fed through equal high-value resistors R1 and equal low-value resistors R4 connected to ground. The junction point of each R1, R4 combination is connected to a voltage comparator C coupled to a monitoring device M giving an audible or visual signal when the voltages fed to the comparator C differ substantially. The outputs from rectifiers 3 are also fed through equal high-value resistors R2 to a common low-value resistor R3 connected to ground. The junction point of R3 with the resistors R2 is connected to each of the comparators C. Modifications.-The separate comparators and monitors may be replaced by a single comparator and monitor which are switched to each channel sequentially. In order to render the apparatus sensitive to the loss of high-frequency components or to the presence of low-frequency hum the frequency spectrum may be divided into bands by feeding the output of each amplifier 2 through suitable filters and providing a, separate monitoring system for each selected frequency band. Alternatively the amplifiers 2 may be made more sensitive to certain frequency bands (e.g. very low or very high audio frequencies).

Filed: 1949-10-04
Abstract: 663,339. Television. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Oct. 4, 1949 [Dec. 11, 1948], No. 25454/49. Class 40 (iii). [Also in Group XX] A television pick-up tube feeding a cathoderay tube receiver through a channel having adjustable non-linear characteristics is employed with X-ray apparatus to produce a representation of the X-ray picture having an increased contrast between predetermined portions thereof. The X-ray image of a body 1 is produced by projection of X-rays from a source 2 on to the fluorescent screen 3 of an image intensifier 4. The intensified but reduced image appearing on the viewing phosphor 5 is projected on to the photo-sensitive screen of a television pick-up tube 6, such as an image orthicon, and the output signal derived by scanning the screen passed to a cathode-ray tube 7 through a channel comprising a linear amplifier 8 and non-linear amplifier 9. Amplifier 9 has a characteristic, Figs. 2 and 3 (not shown), with a linear portion extending over a limited range of input voltages below which no output is produced for application to tube 7 and above which saturation occurs, producing only a limited change in output voltage level for a large change in input voltage. The gain of amplifier 8 and the bias of amplifier 9 are made adjustable whereby signals between selected levels only, corresponding to details of the X-ray image between predetermined intensities, are made effective to produce a fully contrasting picture on the screen of tube 7.

Abstract: 688,323. Fluid-pressure servomotor-control systems; valves. DOMKE, H. Oct. 19, 1950 [Oct. 20, 1949], No. 25529/50. Class 135 [Also in Group XXX] A load handling machine comprises pairs of articulated jibs 5, 7 mounted on king posts 2 by universal ball joints 4 and movable to any desired position by pneumatic servomechanisms controlled by pairs of small scale arms 14, 16 which are operated manually. As shown in Fig. 1 each inner arm 5 is luffed by four rams 9 and is slued by a pair of rams 10 ; further rams (not shown) being provided to move arm 7 about pivot 6 and to operate the jaws 8 of a gripping device. The servomechanism for operating one ram 9 is shown in Fig. 4 and comprises a small piston-cylinder unit 19 which pumps control fluid to and from a valve 21 which admits compressed air to the cylinder of ram 9 to effect corresponding movement thereof. The valve, Fig. 6, comprises a chamber connected through ports E, A and Z with the source of compressed air, the atmosphere and the ram respectively, and has inlet and outlet valves 26, 25 which are operated by an inflatable member 22 connected with the cylinder 19 through the control fluid conduits 20, 24. A cylinder 27 secured to cylinder 9 and having a piston 27a which moves synchronously with piston 9a is connected in conduit 20 and receives from the member 22 the fluid displaced from cylinder 19 after completion of the motion of ram 9, thus causing both of the valves 25, 26 to close and retain the arm in its selected position. The member 22 being subjected to the pressure within the ram, transfers a force to arm 14 proportional to the force on arm 5 so indicating to the operator the weight of the load. To reduce the force exerted by the operator on arm 14 compressed air is supplied from the ram 9 to the cylinder 19 through a conduit 29. In an alternative arrangement the rams are each controlled by a rotary piston valve 21, Fig. 6a, having a control port 22b in a piston 22a which, on rotation, selectively interconnects the ports E, A and Z as before. An inclined ball race 31 engaging the base of the piston effects longitudinal sliding thereof when it is rotated by a lever 24a and since this movement is resisted proportionally to the pressure in the ram the weight of the load is again communicated to the operator. The inclination of the race is adjustable by a screw 32 to vary the force necessary to move the lever 24a. In a further modification (not shown) the seating for ball 4 and the lower anchor for rams 9 are mounted on a sleeve rotatable on the king post by a pair of slueing rams located near the bore of the king post. The Specification states that in place of the pneumatic systems described the arms may be controlled through a hydraulic, electrical or mechanical servo-system.
