Patent number: 7742363Abstract: Mechanical digital display including at least one digit consisting of at least seven segments (1) for the display of alphanumeric characters. Each segment (1) is a body in the form of a bar (1) which can pivot about its longitudinal shaft (3), the said bars (1) having at least two areas resembling a first and a second strip (1?, 1?). These have different appearances, and are arranged along the length of the bar (1) in such a way that the orientation of the bar (1) by rotation about its longitudinal shaft (3) enables either the first or the second strip (1?, 1?) to be made visible. The display of an alphanumeric character is achieved as a result of the dissimilarity of the appearance between the first and second strip (1?, 1?) of the set of bars (1). The pivoting of one or more bars (1) to replace the first strip (1?) with the second strip (1?) or vice versa generates the display of different alphanumeric characters.Type: GrantFiled: September 18, 2007Date of Patent: June 22, 2010Assignee: De Grisogono SAInventors: Fawaz Gruosi, Jean-François Mojon

Patent number: 4423965Abstract: An elongated clock includes a pair of adjacent, cylindrical, rolls providing one roll with five minute segments indicated and a second roll with twelve hours of morning and evening indicated. These rolls are mounted about a shaft connected with a constant speed motor which rotates the minute cylinder at a constant rate. A gearing arrangement at the end of the shaft couples the shaft with the roll indicating hours and turns the hour roll once every hour. A segmented drive gear is coupled to the shaft and includes a pair of teeth which engage a pinion which in turn has every tooth meshing with a gear attached to turn the hour roll. Thus, one complete rotation of the shaft produces one-twelfth of a full rotation of the hour roll. The pinion gear is prevented from overriding after indexing because a locking rim of the segmented drive gear nestles into gear teeth extensions of every other tooth of the pinion gear.Type: GrantFiled: September 30, 1982Date of Patent: January 3, 1984Inventors: Johannes F. J. M. Muller, Joannes A. M. Van Dongen

Patent number: 4277841Abstract: A stepping motor (44) for use in and in combination with an elapsed time indicator (10) of the type including a plurality of indicator drums (102, 104, 106 and 108) and a drive train (FIG. 3) driven by the motor for driving the indicator drum (102). The motor includes a rotor (56) and a stator providing a pair of stator poles (50, 52) including a notch (94, 96) in respective poles faces. The notch creates a pair of pole faces, one of major length and the other of minor length in each stator pole. In a non-current condition, the rotor seeks a dwell or detent position rotationally toward the pole face of greater concentration of iron. When the winding (54) is pulsed, the rotor, within at least the second pulse, moves unidirectionally and between pulses locates a further dwell or detent position. An indicator (154) including a flag (156) is controlled in movement by the motor so that the flag is moved into and out of a viewing window (40) to indicate motor operation.Type: GrantFiled: March 14, 1979Date of Patent: July 7, 1981Assignee: General Time CorporationInventor: Gerald W.
