    摘要： A method for manufacturing a balance-spring for a clockwork movement wherein a spring is formed by winding, from a wire or metal strip, said spring including an inner end intended to be fixed to a balance and a outer end zone intended to be fixed to the balance-spring stud and wherein the whole spring is subjected to a first heat treatment subsequent to the winding step of said wire. The method of the invention is characterized in that it further includes an additional step consisting in subjecting at least said outer end zone to a second heat treatment.This method improves in particular the shock resistance of the balance-spring.

    摘要： A piezoelectric or ferroelectric microresonator of tuning fork configuration has an overall length of from about 100 mils to 500 mils, and a width of from about 15 mils to about 50 mils. In a typical embodiment, the microresonator includes a thin film electrode extending across the bottom surface of both tines, and on the top surface, a first set of electrodes extending along the outer tine edges and a second set of electrodes extending along the inner tine edges adjacent the tuning fork slot. The microresonator stem portion may be attached to a substrate by means of a eutectic pedestal or other mounting. Metal film weights at the tine ends may be used for adjusting the frequency of the microresonator, and the tines themselves may be tapered for improved temperature coefficient characteristics. Various other microresonator configurations are disclosed, as is a method for fabricating the tuning forks microlithographically.

    摘要： An oscillating system includes two identical rotary oscillators each having a rotating mass and a vibratory spring. The rotating masses oscillate in phase opposition, and the two rotary oscillators have respective shafts mounted in spaced parallel relation in working plates. One end of each vibratory spring is connected to the associated rotating mass, and the opposite ends of the two vibratory springs are interconnected by an elastic intermediate spring part, and the two vibratory springs are wound in the same sense. The intermediate spring part extends substantially perpendicular to the shafts and is integral with the two springs. The springs may be helical springs or flat coil springs.

    摘要： 240,505. Schieferstein, G. H. April 28, 1924. Machinery, utilizing inertia to obtain movements in. - An elastically-supported mass excited gradually to movement in a circle or other closed curve by rotary driving means acting thereon through an extremely elastic coupling, constitutes a mechanical system having pronounced natural frequency and stated to be applicable for regulating rotating mechanisms such as motors, generators, &c., electric &c. clocks &c. with continuously-moving hands, phonographs, telescope-movers &c. Various embodiments of the invention are described. In Fig. 1, the mass a constrained by springs b , b , b , b is gradually excited to movement in a circle by a crank g acting through an extremely flexible coupling k. In Fig. 2, the mass is constrained by rectangularly arranged springs b , b and the flexible coupling comprises a crank g formed at the end of a wire coil k. Such coupling means may extend on both sides of the mass a. In Fig. 4, an annular mass a, supported peripherally by a number of radial springs b , b , is driven through a spring k by a concentric crank g, an initial displacement being produced either artificially or by the sag of the springs. In a numbers of forms the mass is supported in the manner of a circular pendulum at the end of a spring b, Fig. 5, or of a rod connected to the spring, Fig. 8, the upper end of the spring being fixed to a support, and the coupling k being in the form of a conical spring fixed to the mass with its end engaging a hole or slot in a crank disc g. One or more arms c may be carried by the pendulum rod as shown in Fig. 8, enabling linear motion to be transmitted to or from the device through an elastic coupling k . In another form, the crank disc g is at the upper end of the pendulum, being connected through a spring, such as k, to a ring secured to the pendulum rod and enclosing the fixed support. In Fig. 9, a pair of weights a , a is supported by a membrane or elastic plate b and executes a tumbling movement. In another form, a pendular mass is supported by a number of spring bars or coiled springs. Slight modifications of the spring coupling means k, shown in Figs. 1 and 2, are described. An elliptical movement may be obtained by an asymmetric arrangement of the springs &c. Specifications 7252/86 and 1644/78, [Class 103, Railway &c. vehicles], are referred to.
