Abstract: 1329151 Ultrasonic probes; ultrasonic testing BABCOCK & WILCOX Ltd 15 Dec 1970 [15 Dec 1969] 59558/70 Headings H4D and H4G Apparatus for recording on a sheet the directional and spread characteristics of the ultrasonic beam of an ultrasonic probe 1 comprises an inner carriage (Fig. 1) for carrying the probe 1, an outer carriage 5 in which the inner carriage 3 is movable laterally and a frame 10 in which the outer carriage 5 is movable longitudinally. In use, a calibrating block 27 (Fig. 2) is attached to the underside of the frame 10. The outer carriage 5 is longitudinally reciprocated by a reversible electric motor 31 controlled by limit switches 15 and the inner carriage 3 is moved progressively laterally by a screw-threaded shaft 7. Further limit switches (not shown) provide for stopping the motor 13 at the end of the traverse of the inner carriage 3 in either sense. The shaft 7 is turned by a spacer wheel 21 engaging a rack 11 during longitudinal movements of the outer carriage 5 in one sense but not in the other sense so that the probe reciprocates in a zig-zag path. The calibrating block 27 includes echo reflectors in the form of semicylindrical cavities 29, 30. While the probe 1 is relatively traversed over the calibrating block 27, a marker is traversed over a recording sheet in correspondence with the movement of the probe 1 over the calibrating block 27. The apparatus is first adjusted to record echoes from one selected cavity 29, 30. The upper surface of the block 27 is recessed to contain a pool of oil as coupling agent between the probe 1 and the block 27. The probe 1 delivers ultrasonic pulses to the block 27 and the marker marks the sheet when and only when the echo intensity is within any one of a plurality of non- contiguous intensity ranges. Circular potentiometers 24 and 26 adjusted by a spur wheel 23 and worm wheel 25 respectively determine the position of the marker relative to the sheet. The marked sheet (Fig. 6) provides a record having a marked zone Z1 where the intensity of the echoes is below a threshold, another marked zone Z3 where the intensity of the echoes is above a threshold, and a blank zone Z2 representing intensities between these two thresholds.

As shown, each roller has an elastic cover 2d and contains boss rings 2b, 2c which are pressed into the hollow roller body 2a and on to the end of a shaft 1 which has grooves 1a for ball bearings 4. The outer race 4a of each bearing is made of pressed sheet metal and pressed into a socket 3a formed at the end of the stationary tube 3 which is centred in a bifurcated retainer 5 by an enlargement 3b. The race 4a is stiffened by a flange 4a3 which has a small clearance with the inner surface of the body 2a to form a seal to prevent ingress of dirt and retain grease. In a modification, Fig. 2 (not shown), the ring 2b is replaced by a sealing ring which coacts with the flange 4a3 and does not extend to the inner surface of the body 2a, a part corresponding to the ring 2c is formed integrally with the body 2a, and a sealing ring pressed into the open end of the body 2a coacts with the outer surface of the tube 3. Modifications are also described in which sealing rings of moulded plastic material are fitted at the open end of the body 2a, the bodies 2a are machined from solid material, the outer races for the ball bearings are fitted over the enlarged ends of the tube 3, and the sockets 3a themselves form the outer races for ball or roller bearings or receive the bushes of plain bearings. Also, the enlargement 3b on the tube 3 may be replaced by a reduced portion, a region with diametrically opposite flats, a pair of annular ridges, or a ring of moulded plastic material. The enlargement may be formed by expanding the tube into a die by compression of a rubber plug placed in the tube between a pair of plungers.

Patent GB-634914-A (GB)
Abstract: 634,914. Frequency measurements. BARBER, N. F., DARBYSHIRE, J., TUCKER, M. J., PIERCE, F. E., URSELL, F. J., and WRIGHT, C. S. Jan. 10, 1946, No. 923. [Class 37] [Also in Groups XL (b) and XL (c)] A recorded wave-form is analyzed by scanning it cyclically at a smoothly-increasing or decreasing speed, the output of the scanning device being applied to a frequency-selective circuit feeding a recorder. The invention is described with reference to the harmonic analysis of a record 10, Fig. 1, of pressures on the sea bed with a time marking 11. The record is wrapped round a rotatable drum 12, Fig. 4, for scanning by a cell 24. The drum is rotated by hand and allowed to slow down under frictional force. The output of the cell 24 is amplified (Fig. 6, not shown) and applied over valves VR65, Fig. 7, to the driving coil of a tuning fork resonant at a frequency of, e.g. 100 cycles/sec.; a pick-up on the fork thus generates a signal which is amplified in valve 6SL7, whose output is fed back over valve VR65A to the input of valve VR65, and is also applied to an amplifier, Fig. 3, feeding a recorder producing the trace R, Fig. 2. The amplifier of Fig. 9 comprises two push-pull valves VR65 feeding a full-wave rectiller 6SN7 whose output includes a monitoring milliammeter m.a. and the recorder; switches P, Q allow adjustment of the rectifier to avoid non-linearity at small inputs. A separate cell scans the time markings and similarly feeds a recorder through a resonant circuit to produce traces T on the record. Since the record is scanned at varying rates, the peaks in record R, Fig. 2, indicate the various Fourier components in the original record 10, Fig. 1, while the peaks in record T, Fig. 2, identify the parts of record R with the speed of scanning. According to the Provisional Specification, the record of Fig. 1 may be made on a magnetic tape. Specification 634,916, [Group XL (b)], is referred to.

Abstract: 651,141. Pressure controlling means for oilfilled cables. COMPAGNIE GENERALE D'ELECTRICITE. April 7, 1948, No. 9786. Convention date, May 9, 1947. [Class 36] A reservoir 1 for an oil-filled cable comprises two chambers 7, 8 separated by a membrane 2 which responds to pressure differences in the chambers without stretching, the membrane being made of an artificial elastomer which is oil and gas-proof between - 15‹ and 60‹ C. The chamber 7 contains gas under pressure and the chamber 8 is in communication with the cable, any expansion of oil in the cable causing the membrane 2 to be pressed towards the position indicated by the dotted line. In the event of an escape of oil from the cable the membrane is distended by the gas pressure, causing an electric contact 16<SP>1</SP> to actuate an alarm. Similarly, in the event of a gas leak from chamber 7 the membrane is caused to operate a contact 17 in an alarm circuit. Any leak of oil through the membrane 2 causes a float 12 to actuate an alarm. The membrane may be made from a polymerized silicone rubber, a polymerized acrylonitrile elastomer, a polymerized chloroprene elastomer, a polymerized thioplast elastomer, a plasticized polymer or co-polymer of vinyl chloride, a plasticized methyacrylic ester, or a fabric to which a coating of any one of the above substances is applied, and may be of uniform or varying thickness. The membrane may be hemispherical, cylindrical, or in the form of bellows.

Title: Power sensor
IPC: G01R19/145
Filed: 1978-11-29
Abstract: A sensor 101 supplies a signal in the presence of a.c. via an amplifier 102 and threshold pulse shaper 103 to three flip-flops 105, 106, 108. These divide the sensed frequency down to an audio frequency and their outputs are combined in gates 107, 109 to provide complementary outputs driving l.e.d's 110, 111. By adding extra flip-flop divider stages any frequency input may be accommodated. This sensor may be utilised both in domestic and electrical fields, primarily as a fault finder for electrical defects of various kinds. The defects may be detected by one simple small instrument and the user does not have to make a mechanical connection to the supply line. The defects which may be detected are firstly whether a supply is forthcoming from any given socket outlet to the particular piece of apparatus being tested. A possible second use is where a user has a break in a long cable, it is possible to at once determine the exact position of the break without mechanical connection and/or having to cut the outer covering of the cable. <IMAGE>
