A brake device has a housing in two parts releasably connected together by bolts. Co-operating pressure fluid passages in the two housing parts communicate pressure fluid from a source to actuators within the housing, and include separable plug and socket connectors located on the respective housing parts so that separation of the housing parts effects disconnection of the actuators from the pressure fluid source. A non-return valve is arranged to close on separation of the housing parts and to ...

A double faced watch has a movement driving a first gearing actuating a first hands array cooperating with a first dial and a second dial 31 on its opposed face cooperating with a second hands array 32, 33', 43. An automatic winding mass 19 is pivoted concentrically to the two hands arrays by a bail bearing the internal housing of which is fastened on a sleeve giving passage to an axle 7, 7', carrying one hand of the first hands array. This axle 7, 7' is used as a driver for the driving of the s...

A brake having axially-expanding brake shoes, comprises an actuating block radially located in a peripheral annular groove formed in a rotating member. The actuating block possesses along its axis, a plurality of cylinders in which slide pistons which apply the brake shoes against the braking surfaces formed by the opposite radially-extending faces of the groove. According to the invention, the actuating block comprises a single, solid, center support plate, and the ends of the cylinders project...

A self-boosting electromagnetic disk brake having an electromechanical actuating device and a mechanical self-boosting device that has a wedge mechanism. A wedge is displaceable parallel to a brake disk and relative to a friction brake lining, and the relative displaceability of the wedge is limited relative to the friction brake lining to one direction, by means of a slaving device. The wedge is decoupled from the friction brake lining in one direction of rotation of the brake disk. As a result...

An electromechanical brake assembly 10 having a pair of selectively movable and dissimilar self energization wedge members 24, 26 which are respectively and independently controlled by motors 30, 34, and which have respectively dissimilar angles of inclination 60, 62, thereby providing a controllably varying amount of self energization.

An electronic timepiece having a pulse generator producing a high frequency time standard signal, a divider circuit formed from a plurality of series-connected divider stages for producing low frequency timing signals in response to said time standard signal and a device for digitally displaying time in response to said timing signals, is provided with a correction circuit disposed in said divider circuit. The correction circuit allows a correction signal to be combined with a carry signal from ...

An electrically driven timepiece is provided with a single user-actuated h button for controlling a modulo-three counter, the counter being utilized to control display advancing pulses derived from an oscillator and frequency divider. In a first state, the counter controls the display advancing pulses to advance the display at a normal rate. In a second state, the counter controls the display advancing pulses to advance the display at a rapid rate to effect a time correction. In a third state, t...

A portable multi-event reminder device includes a battery-powered electrical timer circuit that is programmable with respect to selecting at least two overlapping time periods, so as to generate prompts for at least two functionally related but time-independent events. A solitary two-state switch is the sole input device employed by a user to provide the desired timing programming. The timer circuit is configured to generate a first electrical reminder signal upon expiration of the first selecte...

A shock absorber is disclosed which electrically communicates with an external source of electrical potential. The shock absorber comprises a valve for electrically controlling the flow of damping fluid in the working chamber of the shock absorber. The shock absorber further comprises a connector for allowing the valve to be electrically connected to the source of electrical potential. The connector comprises an adapter shaft communicating with the piston rod of the shock absorber, a female conn...

A device comprises means for distinguishing a short depression from a long depression depending on the period of actuation of a control button (block 14), means for selecting in the case of a short depression a minutes correction mode in which the display advances by one minute for each pressure (block 18) and, in the case of a long depression, an hours correction mode in which the display advances by complete hours as long as the depression lasts (block 19). It further comprises means for defin...
