Title: Improvements in or relating to a method and apparatus for examining the internal structure of a body
IPC: G01N29/06
Filed: 1964-10-30
Abstract: 1,074,070. Ultrasonic inspection devices. M. E. CLYNES. Oct. 30, 1964, No. 44488/64. Heading H4D. In a method for examining the internal structure of a body, e.g. for differentiating between benign and malignant tumours in body tissue, three ultrasonic beams, projected in the same direction and having different frequencies. are separately detected after reflection from or transmission through the structural components of the body and control the respective intensities of the three colours in a tri-colour generating system to produce a colour pattern representative of the internal structure of the body. Three synchronized pulse generators A B, C, operating at different carrier-wave frequencies, drive respective transducers A, B, C for transmitting three pulsed ultrasonic beams Ba, Bb, Bc simultaneously. The three beams are differentially reflected and absorbed by structural components of the body according to the acoustic properties of the structure and according to frequency. The beams are detected after reflection (i.e. a pulse-echo technique) or after transmission through the body by the transducers A, B, C which feed respective tuned receivers A, B, C. The signal levels from the receivers A, B, C intensity-modulate the electron-beams from the three electron-guns 13, 14, 15 respectively of a shadow-mask type colour television tube in which a linear timebase is swept in synchronism with the ultrasonic pulse generators A, B, C. The trace on the colour-tube screen (Fig. 2, not shown) thus comprises a row of bright marks whose spacing and colour indicate respectively the relative position and composition of the internal components of the body under investigation. A colour-film moving at a constant speed relative to the colour-tube screen may be exposed to provide a record of the trace (Fig. 3, not shown). The ultrasonic beams Ba, Bb, Bc may be mechanically scanned by conventional scanning mechanisms, the electron beams of the colourtube being scanned concurrently, e.g. by rotation of a magnetic deflection yoke 18 on the colour-tube in synchronism with a rotation of the transducer array to give a PP1 presentation. Type-B and type-C scans are also envisaged. In a first modification (Fig. 4, not shown) the three transducers A. B, C may be replaced by a single transducer (ABC) which is coupled through an electronic switch to pulse generators (A<SP>1</SP>, B<SP>1</SP>, C<SP>1</SP>) and is energized sequentially thereby at three harmonically-related carrier-wave frequencies. In a second modification, the colour-tube may be eliminated and the signals from receivers A, B, C fed to three xerographic recorders, the developed images being presented through red, green and blue filters and combined.

Abstract: 919,448. Fluid-pressure servomotor control systems. GENERAL ELECTRIC CO. Dec. 15, 1961 [Dec. 19, 1960], No. 44998/61. Class 135. A servo-piston 2 with an output rod 5 is reciprocable in a cylinder 1 to the two ends of which pressure fluid is supplied through restricted orifices (not shown) and is formed with a central recess 6 housing a valve member 7 which is pivoted to the piston at 8 and pivotally connected to an input lever 14. A passageway 10 terminating in a valve seat controlled by a portion 13 of the valve member communicates with a chamber at the end 4 of the piston and a similar passageway (not shown) controlled by another portion of the valve member communicates with a chamber at the end 3 of the piston, the arrangement being such that on movement of the valve member one passageway 10 is opened whilst the other is restricted further to cause corresponding movement of the piston and consequent recentring of the valve member relative to the passageways. The valve member will move the piston directly in the event of blockage of the passageways or the restricted orifices. A spring 19 takes up lost-motion between the lever 14 and valve member.

Abstract: 1,242,419. Calibrating radiation gauges. INDUSTRIAL NUCLEONICS CORP. Sept.23, 1968 [Oct.11, 1967], No.45184/68. Heading G1A. The frequency response of a nucleonic radiation gauge is standardized by adjusting the magnitude of an impedance in the gauge circuit. A detector circuit of the type having a feedback loop including adjustable potentiometers 18, 25 and 27 and resistor 24 is first "zero" and "source" stabilized in known manner. An A.C. generator 38 is then connected in the feedback loop, the generator frequency being chosen so that the peak amplitude of the output displayed on meter 40 will be 3db down on the output when the D.C, source 23 is in the feedback loop. The operator adjusts the capacitor 16 to vary the frequency response of the gauge circuit until the 3db condition obtains. After frequency stabilization the circuit output may be connected to a spectrum analyzer 45 to produce records of the variance of the signal in different parts of the frequency spectrum from which a trained operator can deduce where faults in the process producing the material 14 (e.g. cigarette rod or paper plastic or steel web) are occurring. A plurality of gauges may be standardized from a central point by a multi-plexing switch which sequentially takes them off-line and connects them to zero, source and frequency stabilization circuitry, Fig.3 3 (not shown). In a modification, Fig.4 (not shown) the A.C. source is replaced by a chopper in the radiation path and an error detector is provided which compares the peak level of the output with a reference level, and employs any difference to energize a servo-motor adjusting the capacitor 16.

Abstract: 1,015,691. Protective arrangements. SPERRY RAND CORPORATION. Dec. 19, 1961 [Dec. 20, 1960], No. 45529/61. Heading H2H. [Also in Division H3] In an arrangement for monitoring the voltage of a D.C. source 104, the source 104 is connected through oppositely-poled diodes 218, 220 to points A, B on a potentiometer 222, 212, 224 supplied from a direct voltage reference source 102. The diodes 218, 220 are also connected in an A.C. alarm circuit including transformer secondary winding 226, capacitors 214, 216, 240, and a transistor 238 with resistor 234 and inductor 236. Under normal conditions, the voltage of source 104 has a value between those of the voltages at points A, B so that both diodes 218, 220 are reverse biased and are substantially non-conductive. Should the voltage of source 104 rise or fall, then one or the other diode 218 or 220 becomes conductive and alternating current flows in the A.C. circuit. This biases the transistor 238 so that it conducts and energizes a relay 252 to operate an alarm device 250, e.g. a buzzer, a bell or a flashing light. Fig. 4 (not shown) illustrates a similar arrangement for monitoring the voltages of a plurality of D.C. sources.

Abstract: 1535523 Ramming equipment KOEHRING GmbH 17 Nov 1975 [16 Nov 1974 (2) 30 Aug 1975] 47289/75 Heading B3H Ramming equipment, e.g. a pile driver, comprises a ram casing 2, a ram 25 reciprocable in the casing, a gas filled working chamber 24, a ram cylinder 30 associated with the casing 2 or with the ram and containing a piston operable by a pressure medium and linked to the ram, and control valve means which connect the cylinder through pipe or duct means to a supply of the pressure medium. A pile driver for driving a submerged tubular pile 29 is provided with a cap 27 which rests on the pile and is fitted with an annular seal 26. The ram 25 impacts the cap 27 and as it reciprocates gas inside the chamber 24 is displaced from one side of the ram to the other via ports (34) and a spill duct (33), Fig. 8 (not shown). Pressure fluid is supplied to the ram cylinder 30 by means of hydraulic pumps 6 actuated by motors 5, the pumps supplying fluid directly into a reservoir 7. A flexible element in the wall of the reservoir varies its capacity proportionately to external pressure when the pile driver is used under water. Pressure fluid is supplied continuously under the piston 31 in the ram cylinder while valve means 10 provide an intermittent feed to the upper face of the piston. The pumps and motors are mounted in a driving unit 1, which is slidably mounted on the cylinder 30 and a shaft 38 by means of shock absorbing elements 4. A jacket 3 provides buoyancy and the unit 1 is secured to the casing 2 by tension elements 11 and spring buffers 12. The bottom of the unit 1 is fitted with hydraulic cylinders 13 which co-operate with accumulators 15 and act as shock absorbers when the equipment is working above water. The degree of shock absorption is adjusted by varying the pressure in the accumulator. In an alternative construction, the gas already in the casing is compressed by admitting water into the casing as the equipment is submerged and it is fed to the buoyancy jacket and working chamber so as to equalize the gas pressure in them with that of the surrounding water. The flow of water into the casing may be controlled by valves, Fig 7 (not shown). An impact plate (28), Fig. 3 (not shown), may be provided between the ram (25) and cap (27). In a further construction, Fig. 8 (not shown), compressed gas is supplied from an external source to form a cushion (69) under the cap (27) and into the working chamber (24). The cap (27) is provided with a bore which connects the chamber (24) with the cushion (69), the bore containing throttling constrictions (97) with storage spaces (96) so that the fluctuations of gas pressure as the ram operates do not affect the cushion.

Pivoting of handle 54 causes member 38 to be drawn into the valve block 25 so that a predetermined amount of fluid in an adjustable gap 46 can be blown through a nozzle member 64.  Conduit 73 is connected to the outlet of a portable control unit (10), Fig. 1 (not shown). When switch (79) is closed vibrator 49 agitates hopper 15 and closing of contacts 62, 63 energizes valve (76) through timer (78) which breaks the circuit after a time interval to close valve (76).  A fluid control valve (77) and regulator (75) control the air velocity.  Nozzle 64 has marking flanges to enable the nozzle to be positioned adjacent to engine exhaust ports when the nozzle is inserted into an engine exhaust manifold.  In another embodiment powder from a cartridge 172, Fig.8, fills the uppermost enclosed space 169, Fig.9, of a rotatable metering device 162 until handle 202 is rotated counter clockwise to bring the next enclosed space into the filling position, the metering device remaining stationary by means of a pawl and ratchet assembly on the return stroke of handle 202.  At the end of each counter clockwise stroke of the handle 202, rod (160), Fig. 10 (not shown) is moved to displace seat 152 so that high pressure air from passage 126 Fig. 8, chamber (118) and passage (144) passes through cavity 146 and passage 158 into chamber 108 Diaphragm (130) moves to unseat valve (138) to admit high pressure air to cavity 114 Fig. 8 and thence through passage 140 and opening 142 thus forcing the powder in the lowermost space 169 Fig. 9 through passage 188 Fig. 8 into conduit 194. The high pressure air in chamber 108 is bled out through a needle valve 224 to gradually diminish the air flow thereby providing a uniform dispersion of powder.
