[Also in Division F1] An hydraulic pulse generator 1, Fig. 1, is connected by a long flexible power line 3 to the pressure space 10 of a receiver, e.g. a percussive drill having a control by-pass valve 19 which when moved by a lever so into its open position shown, i.e. drill inoperative connects the power line 3 to a return line 6, and control means at the generator end of the line 3 senses flow conditions in line 6 and serves to prevent the pressure pulses from reaching the major length of the line 3. The control means comprises a pilot valve 27 which when urged upwardly to the position shown against a spring 33 by return pressure upstream of a restrictor 25 connects a make-up pump 4 with the underside of a main control valve 26 to lift the same whereby pulses are directed from line 3 into an accumulator 28. On releasing lever 20 valve 19 closes and the pressure drop in line 6 results in valves 26, 27 assuming their inoperative positions and the pressure pulses being transmitted to space 10. The return stroke of the drill is effected by pressurized liquid in a chamber 13. In a modification wherein the generator 1, Fig. 2, is a cam actuated differential piston 1a, the main valve 55 when in its operative position connects line 3 with the generator chamber 52 which results in piston 1a being lifted from cam 51. In a further modification the generator 1, Fig. 3, is driven through a clutch 60 which is disengaged by flow from the make-up pump 4 passing through the main valve 62 in its operative position; the pilot valve being dispensed with. In a modification the return line includes a cooling radiator for the circulating oil.

Title: Ultrasonic cleaning apparatus
IPC: B08B3/12
Filed: 1964-03-18
Abstract: 1,062,794. Ultrasonic cleaning. BRANSON INSTRUMENTS Inc. March 18, 1964 [March 18, 1963], No. 11554/64. Heading A4F, [Also in Division H4] The frequency of the exciting drive supplied to electro-mechanical wave transducers 22 (Fig. 1) employed in an ultrasonic cleaning bath, is varied automatically to maintain a resonant condition as the load presented to the transducer alters (e.g. changes in the number of article 10 in the bath and in the quantity and condition of the cleansing fluid &c.) so that maximum cleaning efficiency results. This is achieved by deriving from the total drive current that portion which is effective to excite the load variant component of the transducers and then ultilizing this to determing the drive frequency. In one embodiment (Fig. 4, not shown) the transducer, which is shown as an equivalent circuit (28) including a load invariant portion comprising a capacitor (Co) - the capacity of the transducer measured at a frequency well below resonance - and a load variant portion comprising a capacitive component (32) and resistive components (3, 34) is driven by a regenerative feed-back oscillator including an amplifier (36). The circuit further includes a compensating capacitor (Cc) which is adjusted to supply to one end of a summing resistor (Rs) a current equal to that supplied to the other end of the resistor via the load invariant portion (Co) of the transducer so that cancellation of the latters (in Rs) occurs, the voltage across (Rs) thus being that due to current flowing in the load variant portion of the transducer (Rs) is then adjusted so that the amplitude of this voltage (forming the feed-back signal for the amplifier) is large enough to cause oscillation only at a few of the larger peaks in the admittance/frequency characteristic (Fig. 3, not shown) so that as the load on the transducer varies oscillation occurs only during the resonant state of the latter. An alternative arrangement utilizing a balanced secondary winding on the feedback transformers is described with reference to Fig 5 (not shown).
