Abstract: Watch movement with hand display, comprising mobile elements (44, 42), designed to receive the hour (16) and minute (20) hands indicating current time, mounted pivoting to pivot about a first axis (A—A) arranged substantially at the center of the movement and four mobile elements (58b, 60b, 64b, 62b) designed to receive hands displaying complementary functions. According to the invention, the four mobile elements (58b, 60b, 64b, 62b) are mounted pivoting on the movement about second (B—B), third (C—C), fourth (ND) and fifth (E—E) axes arranged on a straight line (X—X) perpendicular to them.

Abstract: The instrument is a slide caliper with inner and outer feelers borne by a slideblock (3) and by a slider (6) which is mounted for sliding on the slideblock via a play take-up device (7).That device comprises a base plate (10) having two symmetric end inclined planes (14) on which two shoes (11) are arranged. The base plate bears a central shoulder (16) pierced by a hole (17) in which there is engaged the stud (25) of a drive and locking screw. Two compression springs (12) are interposed between this shoulder and the two shoes in order to cause the latter to rise on the inclined planes.This device automatically takes up the play formed by the sliding system. It is irreversible.The shoes (11) are narrower than the base plate and means (22) are provided to avoid their rubbing against the walls of the slider.

Abstract: A jointed electronic watch comprises a plurality of watch cases each capable of bearing a different type of display and an energy source. Between the back covers (4, 5, 6) and case bands of each case are sandwiched seals (9, 10, 11) which are coupled together by isthmuses (12) at the line of articulation of the back covers and which are formed as a single piece. Within the isthmuses are arranged electrical conductors adapted to couple together the various electronic components within the plurality of cases.

Abstract: A measuring device for measuring dimensions in which an adjustable reading unit giving a numerical or analog display is fitted in a casing intended to be place on a table, a bracket, a work-bench or any other suitable support.
