Abstract: ABSTRACT OF THE INVENTION      Mercury flow from a reservoir of mercury to a mercury drop capillary extending vertically downward from the reservoir is governed by selective engagement of a sealing surface immersed in the mercury reservoir with a valve seat also immersed in the mercury reservoir to allow for controlled formation of mercury drops at the lower end of the capillary which drops, after formation, are held non-growing or static. The capillary is removable from the housing and when so removed the sealing surface engages the housing of the reservoir to prevent loss of mercury from the reservoir.

Abstract: SUSPENSION SYSTEM IN A RAILWAY CAR          Abstract of the Disclosure A pair of mechanical springs are disposed on an air spring on each side of a truck carrying a car body.  A wide plank disposed between the pairs of mechanical springs and each of the air springs is pivoted to permit vertical movements without tilting of the air springs when the mechanical springs are deflected laterally.  Shock absorber means are connected between the car body and bolster along the longitudinal axis of the bolster to control lateral shocks as when the mechanical springs are laterally deflected.           Mechanical springs in railway cars have employed pairs of mechanical springs in series with pneumatic springs. Multiple mechanical springs, in series with pneumatic springs, have included a heavy outer coil spring and an inner lighter coil spring coaxially nested with the heavy outer spring used to keep the stress levels on the individual springs relatively low.  This arrangement is illustrated in a Patent 3,491,702 to A. G. Dean entitled "Series Pneumatic and Coil Spring Assembly".  The series mechanical and air spring are desirable because the mechanical spring will still give support for the car if the air spring fails.
