Title: Apparatus for energising an ultrasonic transducer
IPC: B06B1/02
Filed: 1975-01-03
Abstract: 1477801 Ultrasonic inspection devices ROCKWELL INTERNATIONAL CORP 3 Jan 1975 [14 Jan 1974] 264/75 Heading G1G [Also in Division H3] The invention relates to the remote energizing of the transducer through a transmission line of  the computer controlled ultrasonic inspection system described in Specification 1376117. Accordingly the pulse generator circuit is situated at the computer and is connected to the transducer 2 through coaxial transmission line 14' which is e.g. 300 feet long. In response to a 3 Ás, 4 kHz sync. input pulse applied at 40, capacitor 55 is discharged through the transmission line 14', so that an accurate repeatable pulse length is produced, which is terminated at a predetermined time by shunting to earth the capacitor discharge current through thyristor SCRZ. The leading edge of the sync-pulse sets flip-flops FF1 and FF2 and triggers monostables MU1 and MU2 so that the trailing edge of the outputs therefrom set the flip-flops FF1 and FF2; FF1 is set after 150ns, and FF2 after between 150 ns and 1À5 Ás, the delay produced in MU2 being varied by variable resistor 45. The difference in delay time so produced, is used to define the length of the transmitted pulse. The flip-flop outputs are inverted and differentiated, at 49, 51 &c. Positive-going sharp pulses are obtained from inverters 53, 54 and are respectively applied to transistors Q 1  and Q 2 . When Qi switches on thyristor SCR1, capacitor 55, which has been charged through transistor Q 3  while the thyristor SCR1 was off, discharges into the transmission line 14' via diode D 1  and Zener diode D 2 . Resistor 60 terminates the line 14' at its drive end in its characteristic impedance to reduce reflections. The delayed timing of the pulse output from inverter 54 quickly terminates the transducer drive pulse, by activating SCR2 and shunting to ground discharge current from the capacitor 55, which quickly falls to a level whereupon the thyristors cut-off and allow recharging of the capacitor, from voltage source V cc , Zener D 2  prevents reflections in the line 14 from damaging the thyristors &c., and limiter 64 prevents damage to receiver preamplifier 61.
Patent GB-600736-A (GB)
Title: Multi diameter screw threading mechanism
IPC: B23G5/12
Filed: 1945-01-03
Abstract: 600,736. Screwing; die-heads. LANDIS MACHINE CO. Jan. 3, 1945, No. 277. Convention date, Feb. 19, 1944. [Class 83 (iii)] In a self-opening die-head machine for screwing work of more than one diameter, such as a stud 54, Fig. 5, having an entering portion A of smaller diameter than the main screw-thread B, a latch is tripped when the dies reach a point 53 on the work to allow the head to open slightly and so cut the larger diameter thread. The die-head, which is of the kind described in Specification 419,188, has the chaser holders 15 held in closed position by a ring 17 which is locked by a locking ring 21, the closed position being determined by the axial position of an operating ring 14. A yoke 10, pivoted on the machine frame at 23 is connected by pivots 11 and a yoke ring 13 to the operating ring 14 and carries a latch pin 30 engageable with a latch 32 vertically slidable in a bracket 34 which is adjustably secured to the machine frame. The latch is pressed upwardly by a spring 44 so as to cause a pin 45 projecting laterally therefrom to engage a trip rod 46 attached to the work holder 29. In operation, the bracket 34 is set so that the latch 32 holds the yoke 10 in such a position that the ring 17  is held slightly away from the locking ring 21 and relative axial feed of the work and diehead will cause the latter to cut the thread A. When the point 53 is reached, an adjustable sleeve 48 on the rod 46, having a bevelled end  engages the pin 45 to draw the latch downwards and release the yoke, which may then be moved by the head-opening springs to allow the ring 17 to engage ring 21 and set the head for cutting the larger diameter B. The lower end of the pin 30 on the yoke is bevelled or rounded so that the yoke may move gradually when released to cause a gradual transition between the diameters of A and B, the degree of bevelling determining the abruptness of the transition. On completion of the screwing, at the point 55, adjustable nuts 28 on a trip rod 26 attached to the work holder rock the yoke to open the head as described in Specification 419,188. For re-setting the head the work is withdrawn, whereby the sleeve 48 allows the latch 32 to rise and nuts 27 on the rod 26 rock the yoke to closed position in which it is held by the latch. Additional latching mechanism may be provided for cutting screw-threads of more than two diameters.
