A housing is disposed coaxially inside of the casing, and a shaft is mounted eccentrically in the housing. The casing and housing are angularly movable relative to one another. A drivable spindle is mo...

An abrasive machine for grinding material from an outer surface of a workpiece. The machine includes a rotationally driven casing having an opening at one axial end thereof. The opening is defined by an annular edge which constitutes a grinding wheel. A shaft is disposed within the casing and forms a space whose center axis is offset from the center axis of the casing. Disposed within the space an...

The device includes an optical track reader which has optical fibres terminating in the projector and in a separate audio pre-amplifier unit. The projector termination faces the optically recorded track of a film. A light source on the other side of the film delivers light which is modulated by the recorded track. The modulated light is carried by the optic fibres to the pre-amplifier. Light dete...

In a drive unit for electric vehicles, each wheel (3) of the vehicle is driven by its own electric motor (1), by means of a drive shaft (2). Each electric motor (1) is hollow and houses, within a central axial cavity (4) in the rotor (1b), a joint (G) for transmitting the drive to the drive shaft (2) of the wheel (3).

A motor-vehicle dashboard (1) has a wall (5) projecting from the instrument panel (3) having an aperture (7) within which there is pivotally mounted the flattened body (10) of a liquid crystal video display, which can be moved between a folded rest position, lying in the plane of the wall (5) and an unfolded position of use, substantially orthogonal to this plane.

The invention relates to a surface-mounted plug socket of the type which comprises at least three terminals. According to the invention, the terminals are arranged such that they are aligned with one another and a terminal strip (50) is assigned to the surface-mounted plug socket, which terminal strip (50) has at least one group of pins (52A, 52B) which project from a base plate (51) at a distance...

The objective of this invention is to prevent the deposition and the scale growth of the limestone present in the water flowing inside a pipeline, and in any domestic appliance; it enables the existing deposits to be removed. The apparatus (1) is made up of a double generator of intermediate frequencies, transmitting the induction of currents regulated by two spiral cables (2 and 3) wound around t...

The device moves the steering column (10) axially and adjusts its angle of slope on a supporting frame (30) by means of separate electric motors and reduction gears (31,32). The dashboard (20) is moved simultaneously by two parallel arms (33,34) on opposite sides of the frame, jointed to the latter and to the slope variation motor (32) by an elbowed push-rod (43), a toothed sector (45) and a pinio...

The device comprises a body base having a means of fixing to the object. The body base comprises a disc (1) at the surface of which extends a hollow cylinder (2) of smaller diameter than the disc. The assembly is closed by a cylindrical cover (3) having a slightly greater diameter than the disc. The cover height is greater than the cylinder and is fixed by its open end (3a) to the disc periphery (...

A method for making an activatable and/or deactivatable magnetic ink for printing, on all types of products, magnetic indicia in replacement of anti-theft tags or filaments, wherein said printed indicia can be detected by security magnetic or electromagnetic gates. The printed ink includes iron, iron oxide and a ferrosilicon cobalt or ferrosilicon nickel alloy in powder form, in an organic binder.

The jib consists of at least three sections (2, 3, 4), connected by articulated joints with horizontal axes (A) and deployable at various angles to one another. The first section (2) is articulated to the earth-moving vehicle and the last (4) is equipped with a bucket (5) or other tool, while hydraulic cylinders control the three sections' positions. The last section (4) and the intermediate secti...
