20140286143 | TIMEPIECE BALANCE SPRING ADJUSTMENT MECHANISM - Mechanism for adjusting the active length of a timepiece balance spring whose outer end is fixed to a balance spring stud secured to a bar, this mechanism including two pins for clamping or touching the outer coil of the balance spring during the operation of this balance spring. | 09-25-2014 |
20150138934 | TIMEPIECE BALANCE SPRING STUD-HOLDER WITH NO SCREWS - An assembly for holding or supporting a timepiece balance spring includes a balance spring stud and a stud-holder. The stud-holder includes a device to secure the stud-holder to an escapement mechanism. The balance spring stud includes a lateral bearing surface defining a direction of holding or supporting the balance spring. The stud-holder is in two parts, and includes a rigid structure carrying the securing device, and a strip spring pressed against this rigid structure and including at least one elastic lip defining, with this structure, a chamber for receiving this stud and cooperating with this lateral bearing surface of this stud to hold this stud in an indexed locking position. | 05-21-2015 |

20080273425 | Pendulum Clock - A pendulum clock comprising a pendulum clockwork with acoustic signaling means contained in a housing wherein the housing comprises vertical surface elements made of metal, optionally comprising openings in a minor part of the surface thereof, and wherein the housing comprises at least one horizontal surface element wherein the ratio of the specific surface mass of one horizontal and of the vertical metal surface elements is at least 3. | 11-06-2008 |
20090073814 | Low-Displacement Pendulum - A gravity pendulum, referred to as a low-displacement pendulum because it does not displace air as it rotates, is disclosed. The low-displacement pendulum uses an unbalanced wheel instead of the more conventional suspended bob. Because the pendulum does not displace air as it rotates, it eliminates an important component of air drag that causes energy loss in a normal pendulum. The low-displacement pendulum also eliminates errors caused by variations in barometric pressure. In addition, it can be easily thermally compensated without the use of special materials, such as Invar. | 03-19-2009 |
20100128574 | ENHANCED COMPOUND PENDULUMS AND SYSTEMS - Enhanced compound pendulums provide thermal compensation and/or barometric compensation, such as for a mechanical clock system. The enhanced compound pendulums are simple to construct, and can be more easily compensated than conventional, single-bob pendulums. The enhanced compound pendulums typically comprise material that is added above the point of rotation. Thermal expansion factors for components of the enhanced compound pendulums may preferably be chosen to provide thermal compensation to the first order. In some embodiments of enhanced compound pendulums, volume is added above the pivot to provide barometric compensation, such as by equalizing the moments above and below the pivot, or by providing geometric symmetry above and below the pivot, with a lower density above the pivot. | 05-27-2010 |
