Abstract: The present invention relates to a bus control buffer amplifier. The output terminal is associated with a first pull-down N-channel MOS transistor and with a second pull-up N-channel MOS transistor. The first N-channel MOS transistor is directly controlled by an input signal. The second MOS transistor is an N-channel transistor, and its gate is controlled by a third pull-down N-channel MOS transistor directly controlled by the input signal, and by a fourth pull-up N-channel MOS transistor, which is controlled by the inverted input signal. The fourth N-channel MOS transistor has a very abrupt drain-substrate junction.

Abstract: A device for monitoring the gait of a horse comprises a device (4) for measuring displacement parameters of the horse (2) along at least one axis (Z), processing device (5, 8) for processing the signals coming from the measuring device (4), microprocessor for comparing the amplitude of the output signals from the processing device means with at least one given value characterizing a gait error of the horse (2), and a device (10) for indicating a gait error.

Abstract: The invention relates to a device for maintaining on a non-horizontal surface an apparatus adapted to move along said surface.Said device consists, according to the invention, of a support (1) adapted to move normally to the surface carrying the apparatus, of a rocking lever (5) having a flexibility held within a certain range to allow it to accommodate changes in curvature, and of at least two suction cups mounted close to the ends of the rocking lever. There is thus afforded a more reliable, less expensive holding effect.

Abstract: Method and installation for depositing materials on an ocean bed in accordance with a given line in which the autonomous vehicle is displaced on the ocean bed by accurately following said line, whereby the vehicle is provided with a hopper, a ship is moved on the surface of the ocean roughly in accordance with said line, the materials are discharged from this ship towards the hopper and are guided by means of a pipe suspended beneath the ship and whose lower end is not integral with the hopper, wherein the propulsion means of the pipe disposed at the lower end thereof are operated so that the lower end of the pipe is forced to remain above the hopper.

Abstract: A submarine vehicle for collecting and raising materials resting on the sea bed at great depths, of the type comprising a load-bearing structure, collecting elements for the materials, storage silos for storing the materials collected and/or the ballast material, transfer means between said collecting elements and said silos, and main propellers for advancing the vehicle on the sea bed, said vehicle being characterized in that said load-bearing structure is made of a buoyancy material, said structure being in the form of a ring having a longitudinal plane of symmetry and defining the stem, stern and sides of said vehicle, and defining between them a free central space, the outer surface of said structure forming the hull of said vehicle, said storage silos being arranged in the free central space and fixed to said load-bearing structure, said collecting elements being arranged in front of and below said stem, said main propellers also being fixed to the lower surface of said load-bearing structure.

Abstract: Method and machine for manufacturing grids from lead-based metal for use in storage batteries of the type wherein a casting is first performed of grid blanks the periphery of which is irregular and the size greater than that of the grid to be obtained, these blanks being thereafter cut out in an automatic press. In view to increase the rate of output of the press and to improve the quality of the grids, the press is supplied sequentially from a continuous grid-blank feeding conveyor and at least one final lateral centering of the grid blank is performed in the press by the combined action of two pusher members tapping on each side of the grid blank in a transverse direction passing substantially from the center of mass of the grid blank.
