Abstract: In an electronic watch, the content of the memory associated with the adjusting circuit of the division ratio of the frequency divider is modified at each correction of the display to compensate for the frequency error of the crystal oscillator and to thereby reduce the running error of the watch.

To compensate for the frequency variations due to manufacturing tolerances, age and temperature, correction circuits are incorporated into such watches. When an operator acts on a switch on the case of the watch to correct the time display indication, the content of the memory is modified to correct for the frequency error of the crystal oscillator.

Abstract: This invention is an improved turbofan engine having a variable geometry fan duct which reduces stator source noise emitted from the engine. Attached to the inner wall of the fan casing near the fan stators is a pneumatically actuated annular membrane having two operating positions.

Abstract: In the embodiments shown, the device comprises a turbine wheel, rotatively journaled, having a peripheral, grooved surface onto which rounds of shot are impelled, under steam pressure, to rotate the wheel so that torque power might be derived therefrom. The turbine wheel, in turn, rotates a pulley -- by means of a drive belt -- which operates a sluice-type gating device. The latter device cyclically opens and closes off the pressured steam supply, and feeds a missile -- a round of shot -- to a conduit which terminates in adjacency to the turbine wheel, in order that the round, the missile, will be impelled through the conduit to impact upon the grooved surface of the turbine wheel and deliver a frictional, glancing, energy-transferring blow to the turbine wheel. The turbine wheel is rotatively carried on a support which is pivotally mounted, so that the turbine wheel can be moved into and out of proximity with the missile-impelling conduit in order to optimize missile impact.

The clutch has downwardly-facing teeth having drive surfaces and slip surfaces. An auger or second agitator portion coaxial with the first agitator portion has cooperating upwardly-facing teeth.

During an opposite rotation of the first agitator portion, the slip surfaces engage one another and, where the contents of the washer basket retards a reverse movement of the auger, the teeth will slip past one another, with the clutch member reciprocating vertically upon its splined connection. An annular cushioning member placed between the clutch and the agitator parts cushions impacts between the teeth during such reciprocations by controlling the depth of tooth engagement.

Abstract: The pressure drop through and the circumference of filter rods for cigarette filters or the like are determined by a completely automated rod test station that consists of a measuring unit and a computer. The measuring unit has a transport system for rapidly moving a filter rod first into a pressure drop gauge and next into a pneumatic circumference gauge and then ejecting it.

The analog electrical signals produced by the transducer are converted to digital signals which are input to a computer. The computer corrects the measured signals indicative of pressure drop in accordance with any error detected between the measured drop across the calibration standard and a stored internal constant representing the calibrated pressure drop for the standard during each test sequence.
