The invention relates to a timepiece consisting of a main plate () having the following components mounted thereto: a time base which is formed by a tourbillon () comprising a rotatable frame, which appears in an opening () in the dial () thereof; and time information display means which are controlled from the time base. The aforementioned display means comprise a rotatable ring () which appears in the opening () in the dial, co-axially around the frame, and ring drive means.

Mechanical timepiece comprising a tourbillon

A time-setting mechanism for a clock movement with perpetual Julian date comprising a device for driving a date indicator including driving means for moving forward said indicator by one jump every twenty-four hours. The movement has an adjusting device for automatically moving said indicator by a number of steps taking into account months with 28, 29 or 30 days, said device comprising a rotary cam driven by at least one step every twenty-four hours, said cam having a profile for steering a sensor bringing about: the oscillating movement of a moving mechanism provided with a pawl system for moving forward the date indicator by the required additional number of adjusting steps; and for moving forward said cam by a number of steps equal to the number of said indicator adjusting steps so as to make it move one complete cycle per year.

Time-setting mechanism for clock movement with perpetual julian date

A miniature peristaltic pump includes a rotor with three turning rollers, a support piece with a rounded portion arranged substantially concentric to the rotor and against which, when operating, the rollers are brought to compress a flexible tubing connected to a reservoir of solution to push it outwards and for automatically compensating positional deviations between the roller and the support piece. Each roller has a substantially cylindrical body and a shaft on which the body is rotatably mounted. The ends of the roller shafts are located in oblong slots radially recessed in the rotor. The compensating device includes two springs arranged at the respective ends of the shafts and have a central port concentric to the rotor and three curved spring arms, one for each roller, with one end connected to the central part and the other end bearing on the corresponding end of a roller shaft to push it outwards and thus enable it to exert a substantially constant force of pressure.
