Title: Ultrasonic pulse-echo devices
IPC: G01N29/34
Filed: 1971-02-11
Abstract: 1319942 Ultrasonic inspection devices POLSKA AKADEMIA NAUK ZAKLAD DOSWIADCZALNY BUDOWY APARATURY NAUKOWEJ UNIPAN 11 Feb 1971 4426/71 Heading H4D In an ultrasonic pulse-echo system for inspecting a region at a selected depth within a test object, the device for selecting that depth includes adder circuits through which control voltages are applied to level-detectors. The embodiment shown provides adjustable delays for both the acoustic transmission pulse and the time-base sweep initiation of a flow indicator. The selected depth and the pulse repetition frequency are determined by the frequency of sawtooth generator 1 whose output 10 feeds resistive adder circuits 2 and 3 which receive also a D.C. voltage from unit 7 and an adjustable D.C. voltage from unit 8. When the summation voltages from 2 and 3 pass the threshold level U of level-detectors 4, 5 the detectors are triggered and thus provide output waveforms U4, U5 respectively (each shown for two different frequencies of the sawtooth generator 1). The acoustic pulse transmission is triggered by the negative-going edges of waveform U4 and the indicator time-base sweep voltage U6 is triggered by the negative-going edges of waveform U5. Waveform U6 from the time-base sweep generator 6 is passed via rectifier/capacitor network 9 to adder 2 to advance the negative-going edges of waveform U4 if unit 8 is set to give a sweep delay which would otherwise be shorter than the delay provided by units 7, 2 and 4. This ensures that the transmission pulse triggering occurs just before or during the time-base sweep.

Title: Process for converting striped tubular knitted fabric to  heat-stabilized stripe matched tubular fabric
IPC: D06H5/00
Filed: 1971-02-01
Abstract: 1339494 Finishing fabrics SAMCOE HOLDING CORP 1 Feb 1971 3633/71 Heading D1S Striped tubular knitted fabric is converted to heat-stabilized, stripe-matched and straightened tubular fabric by spreading the greige fabric to desired width and maintaining the fabric under lengthwise tension, slitting the tubular knitted fabric longitudinally while the fabric remains in greige condition, shifting the opposed slit edges of the greige fabric longitudinally and realigning them to convert the spiral stripe configuration to a circular stripe configuration, rejoining the slit edges together in the re-aligned condition, straightening the realigned stripe configuration of the greige fabric by selectively advancing, retarding and. distorting portions of the fabric while conveying the fabric generally, in an advancing direction, until the stripes are disposed at right angles to the axes of the fabric, and thereafter processing and heat-setting the fabric. As shown, a tubular knitted greige fabric 10, made of at least in part heat-settable yarns, e.g. polyester or nylon, or made of at least in part non-heat-settable yarns impregnated with a heat-settable resin, and having a helical coloured stripe 12, is fed in flattened form around tension rollers 24, under an adjustable weighted dancer roll 25 and over a guide roller 26. A knife 13 longitudinally slits the fabric whilst it passes over an internal belt or frame stretcher 14. The stripes on the upper slit edge of the fabric are re-aligned with the lower edge by three rollers 16, 17, 18 acting upon the upper fabric layer only. The realigned edges are sewn together by an overthe-edge sewing machine 27 provided with a knife 28 in advance of the needle 34 to trim of the margin edges 29 of the fabric which edges are blown by an air jet tube 30 into a disposal conduit 31. The tube 30 is positioned so as to tend to flatten the fabric edges. The re-aligned stripes 12a are straightened by rollers 36, 37, 38. The subsequent processing of the fabric may include impregnating with at least one liquid solution, setting the fabric to a desired geometrical form by internal distention and drying. Thereafter, the fabric is heat-set, e.g. in a high temperature dryer.

Abstract: 1352856 Cathode-ray tube apparatus INTERNATIONAL COMPUTERS Ltd 1 Dec 1971 [20 Nov 1970] 55175/70 Heading H4T The trace on a dark trace cathode-ray tube used in information processing apparatus is erased by exposure to heat from a plurality of flash tubes 1, 2, 3, 4 fired in sequence by trigger pulses from a recirculating stepping counter 17 controlled by an erase unit 24. With this arrangement the period between successive flashes from each tube is sufficiently long for the tube to become cool and for a capacitor in control units 5, 6, 7, 8, charged via respective resistors and supplying the flash energy to be recharged so that erasure may be effected at a high cyclic frequency. The use of four flash tubes allows the display information to be regenerated at five to eight cycles per second and other numbers may be employed in dependence on the frequency of erasure required. The use of a plurality of flash tubes also allows a conservative charging current to be employed for the capacitors.

Title: Converter for converting displacement into electric current
IPC: G01D5/20
Filed: 1971-06-30
Abstract: 1353779 Measuring displacement electrically: measuring mutual inductance COMPTEURS SCHLUMBERGER 30 June 1971 30739/71 Headings G1N and G1U Apparatus for measuring displacement, due for example to fluid pressure in a chamber 5, comprises a transformer 1 with a core 2, movable in response to variations of said pressure so as to vary the coupling between primary and secondary windings 11, 21 respectively, the secondary voltage Vs being rectified at 22 and applied to a comparator 24 producing the difference voltage from a reference value Vr' which difference acts through amplifier 6 on field-effect transistor 14 to vary current I, in the primary winding so as to nullify the difference voltage which current IP is measured at 13 and represents core displacement and therefore fluid pressure. It is shown that IP is independent of supply voltage variations and temperature changes. The transformer is energized by an A. C. source 12 and the reference voltage source is a further transformer 15 coupled to rectifier diode 25a and a voltage divider 28, 29. In an alternative embodiment Fig.2 (not shown) the transformer is energized at a frequency of 400 Hz by a chopper circuit including a multi-vibrator (16) driving two pairs of F. E. Ts and supplied from a D. C. source (12'). A shunt circuit is provided across the series connection of the F.E.T 14 and primary winding 11 with a fixed resistance (34) of value Rp, which shunt includes an F. E. T (31) in series with a fixed resistance (32) of value Rd and a Zener diode (33). A differential amplifier (35) controls the F.E.T. (31) to maintain the potential drop across the resistance Rp equal to that across the series combination of Rd and the Zener diode. It is shown that there is then a linear relation between the current IP through the primary winding and the total primary current Iz, which is measured. As before IP is varied by means of F.E.T. 14 to maintain the secondary voltage at a constant value. The reference voltage is derived from a voltage divider (28, 29) shunted across the D.C. source (12'). In a further embodiment Fig.3 (not shown), the supply is A. C. , the Zener diode (33) is eliminated and instead a reference voltage Vo is taken from a voltage divider (28', 29'), in parallel with that 28, 29 shown in Fig. 1, which reference voltage is summed with the voltdrops across resistors Rd Rp and the resultant applied to a differential amplifier (37) controlling a shunting F. E. T. (31).

Title: Lightweight positive lock coupling
IPC: F16L37/24
Filed: 1999-04-14
Abstract: In the first embodiment, a coupling assembly is provided wherein the inner peripheral diameter of an annular spring is sized to be threadably received over the threads of a coupler and is held in a recess formed by the ends of threads and the edge of a shoulder. This structure minimizes the diameter of the annular spring and lock ring to minimize both the size and weight of coupling assembly. Additionally, it provides a quick connect, quick disconnect coupling and has a peripheral stripe to provide a visual indication of its connected or disconnected status. In the second embodiment, a wavy spring is split which allows its diameter to be temporarily enlarged so that it can be received over the threads of the coupler and then spring back to its original smaller diameter so that it is held in a recess formed by the ends of the threads and a coupler flange. This structure also minimizes the diameter of the annular spring and lock ring to minimize both the size and weight of coupling assembly. This structure also provides a quick connect, quick disconnect coupling and has an indicator stripe to identify whether or not the coupler is in locked position.
