    摘要： An autonomously operating pendulum mechanism, adapted to be attached as a unit to a clockwork, comprises a supporting plate adapted to be attached to a clockwork casing in overlying spaced relationship to the front face of the casing. The supporting plate is fastened to the casing by a fastening device which is concentric with the spindles for the clock hands and through which said spindles may project to the exterior of the plate. A pivot bearing is provided on the supporting plate vertically above the spindles adjacent the upper edge of the casing, and the lower edge of the supporting plate carries a circuit board having an electrically energizable coil thereon located immediately below the clockwork casing comprising a portion of an electrical drive mechanism. A pendulum arm extends from the pivot bearing for swinging motion across the front face of the casing in the region between the supporting plate and casing, and has, at its lower end, a permanent magnet which cooperates with the coil to drive the pendulum. The pendulum arm is shaped to define two portions which are disposed in angular relation to one another so that the upper portion of the arm swings in a limited region between the clockwork spindles and one side of the clockwork casing while the lower portion of the arm below the spindles swings between points which are substantially equidistant from the opposite sides of the clockwork casing.

    摘要： This invention relates to electric clocks and chart recorders driven by crystal controlled electric motors. The motor includes two stator plates, a rotor and a drive coil surrounding the legs of the stator plates. The rotor carries a pinion which drives the first gear of a mechanical gear train located between two side plates consisting of synthetic resin material. One of the side plates carries at least one bearing for the rotor and a plurality of projections which fit into holes in the stator plates and serve to position the stator plates in relation to the rotor. Electric pulses are supplied to the drive coil by an electronic frequency divider circuit having a push-pull output stage; a zener diode is connected in parallel with the power supply to the divider circuit and the drive coil to enable the motor to operate satisfactorily over a range of supply voltages. For this purpose, the drive coil preferably has a resistance of more than 1K and a resistor is connected in series between the supply and the zener diode.

    摘要： A clock, having a shaft which rotates in unison with the clock hands, is provided with a bell tone apparatus adapted to be actuated at periodic intervals to provide an audible tone. The apparatus comprises a bell mounted on the clock housing, a hammer supported by a spring adjacent the bell, and a cam mounted on the shaft for rotation with the shaft, the cam being located at a position adjacent the hammer to engage the hammer and move it progressively away from the bell as the shaft rotates. The cam is shaped to release the hammer from engagement therewith at a predetermined angular position of the rotating shaft whereby the released hammer is impelled by the spring back toward the bell to strike the bell and thereby provide an audible tone.

    摘要： There is provided an alarm clock comprising an open-end clock case, a plate carrying the clock mechanism and an adjuster wheel for adjusting clock time and alarm time. The adjuster wheel is mounted for free rotation on a shaft which has a pinion mounted on one end for rotation therewith. The pinion co-acts with the adjuster wheel and drivingly engages the different gears of the clock hand and alarm hand adjusting mechanism. Located between the pinion and the adjuster wheel is a slip coupling. The clock case is provided with an opening through which the adjuster wheel protrudes and has further openings which receive corresponding studs located on the clock mechanism carrying plate. The studs have rubber surfaces and serve as feet for supporting the clock in its normal position of use.

    摘要： An electronic circuit for driving a mechanical oscillatory system with stabilization of the amplitude of the system includes a working transistor having a working winding in its emittercollector circuit and a control winding in its base-emitter circuit, with its working point being determined by a voltage divider having a tap connected to its base. A second transistor is provided and its emitter-circuit forms one branch of the voltage divider, with the control winding being also connected in the base-emitter circuit of the second transistor. Thereby, control signals of the control winding, effecting modulation of the working transistor, simultaneously effect modulation of the second transistor in dependence on the amplitude of the oscillatory system. The transistors may be identical or may be complementary. When the transistors are complementary, the control winding is connected between the bases of the two transistors.
