Abstract: The invention concerns an apparatus comprising an arm (4) which, mounted on a support at one of its ends, comprises several elements (5, 6, 7) articulated on one another about horizontal pins (8, 9) and equipped, at its other end, with a tool-holder (15). At its free end, the arm is equipped with a rotary actuator (12) with rotation pin (12) transverse to the hinge pins (8, 9) of the elements (5, 6, 7) of the arm, and on the lower part of which is fixed a housing (15) containing a motor (16) designed to drive an output shaft (23) transverse to the rotary actuator axis and at the tip of which is mounted cantilevered a tool (33, 34). The invention is applicable to tillage on steep grounds or with marked irregular features, such as trenches.

Abstract: The invention concerns a method for automatically moving on the ground a tool mounted at the end of an articulated arm. It consists in bringing the tool (7, 17, 27) onto a first point of the surface and in calculating the co-ordinates of said point; in bringing the tool onto a second point enabling to set a first axis of co-ordinates of the working plan and to determine the furthermost point to be reached on said axis; in bringing the tool onto a third point close to the second co-ordinate axis and enabling to define the position of the frame of reference of the working plan, then in a fourth point delimiting the zone plane inside which the work will be performed and in defining a working plan for the tool capable of being superimposed with the working surface so as to enable it to cover, by discontinuous or continuous movements, the entire working surface.

Abstract: The use of protected active ingredients, preferably methionine, protected against degradation in the rumen as a hepatoprotective agent is disclosed.

Abstract: A blank consisting of a spirally wound fiber for use in the manufacture of a fiber reinforced article of composite material is made by winding the fiber onto a helical track on the surface of a frusto-conical spindle, covering the wound fiber with a thermoplastic binder which sets to form a frusto-conical shell encasing the fiber, removing the shell from the spindle and placing the shell with its base on a plate, and heating the shell starting from its base so as to soften it and cause it to progressively collapse onto the plate to form a disc comprising a spirally wound fiber. If necessary the collapse of the shell may be assisted by pressing on the shell in a direction towards the plate.

Abstract: A method of making cheese with milk obtained from animals which have received feed supplemented or complemented with an amino acid in a protected form. The amino acid is preferably lysine and/or methionine.

Abstract: The control circuit comprises means for measuring current flow in the motor winding including an auxiliary transistor and means to form periodically a current mirror from such auxiliary transistor and one of the transistors coupled to the winding for applying thereto energization pulses, i.e. motor drive pulses, catch-up pulses or check pulses.

Abstract: The timepiece comprises a first motor (8) driving the seconds hand (s) independently from the other hands indicating the minutes and the hours which are driven by a second motor (4). A logic circuit (5) is capable of controlling the first motor (8) in response to the actuation of control elements (C,S1, S2) external to the electronic circuit of the timepiece or by means (6) internal to this electronic circuit and in response to time base signals delivered by a frequency divider (2) so that the seconds hand indicates informations which are different from the ones for the display of which it is normally provided.

Abstract: An electronic watch having a circuit for permitting it to be stopped in a state of minimum consumption. The watch has an oscillator, a frequency divider comprising flip-flops and a display, with the display and at least some of said flip-flops being connected to a common line so that a signal applied to the common line places them in a state of minimum consumption. The circuit including a switch connected between the common line and a terminal of the power supply and at least two MOS transistors connected so as to apply the signal to the common line when the switch is closed.

Abstract: An electronic digital watch including a device for enabling the correction of the minutes and seconds display. The device includes a delay circuit which only enables a correction to be effected if the push-button for correcting the display is actuated for a predetermined time, and means for resetting the seconds display to zero and, if the watch is slow, advancing the minutes display by one.
