Abstract: A small mill is essentially composed of a feed chute (1) discharging onto a rotor (2) equipped with milling and/or cutting hammers (3) interworking with a milling housing (4) that is equipped with screening walls (5), a crusher element (6) that can be provided upstream from the rotor (2), above the feed chute (1) and at a distance from the latter. The mill is characterized in that the axis of the rotor (2) is inclined relative to the axis of the feed chute (1) by forming an acute angle with the latter. This mill can be applied more particularly in the field of processing materials of any origin, especially by shredding with crushers, hammer mills, or the like.

Abstract: A pre-grinder or pre-shredder apparatus, essentially made up of at least one drive unit (1) including a hydraulically or electrically driven motor (2), a reduction gear (3) and at least one shredding element (4) connected thereto and mounted on a frame (5), a wall, a feeder chute or any other mounting. The reduction gear (3) of the drive unit (1) of the pre-grinder or pre-shredder forms an element for attaching and supporting at least one shredder element (4) and is made up of a stationary portion (3?), attached directly to the frame (5) of the pre-grinder or pre-shredder or on a mounting or a wall of the latter, and by a mobile portion (3?), the shredder element (4) being inserted on the mobile portion of the reduction gear. The apparatus is useful in treating materials from any source, in particular by shredding using grinders, hammer mills or similar devices.

Abstract: The invention concerns a device for assembling longitudinal edges of panels, laths or wainscots (1), consisting of at least a male part (2) equipping a longitudinal edge of said panels, laths or wainscots (1) and of at least a female part (3) with matching shape provided on the other longitudinal edge of said panels, laths or wainscots (1). Said device is characterised in that it provides force distribution and the longitudinal edges bearing the male (2) and female (3) parts extend along parallel oblique planes. The invention is particularly suited for the building sector, in particular for floor covering, wall sheathing and ceiling panelling, particularly in the form of panels, laths or wainscots of different materials, such as wood, skin materials, synthetic materials.

Abstract: Device for assembling edges of panels, laths or sheathing includes at least a male part provided on a longitudinal edge and/or a transverse edge of the panels, laths or sheathings and at least a female part of matching shape provided on the other two longitudinal and transverse edges of the panels, laths or sheathings. The device is characterized in that the male and female parts are provided with at least an element for assembling by impact or pressure two consecutive panels, laths or sheathings by their adjacent edges along an oblique direction, the panels, laths or sheathings being initially offset in height and mutually parallel and their male and female parts being then partly mutually engaged. The device is applicable in the building sector, for floor, wall or ceiling finish, in the form of panels, laths or sheathings made of different materials.

The male portion (2) is in the form of a longitudinal tongue inclined upwards, the female portion (3) having matching cross-section and inclination. The device is equipped with vertical load transfer elements in service position. The invention is more particularly useful in the building sector, in particular for flooring, wall facing or ceiling finish, with panels, laths or wainscots made of different materials, such as wood, skin materials and synthetic materials.

Abstract: A Hammer mill, comprising discs (1) mounted on a drive shaft (2), crosspieces (3) for spacing apart the discs (1), hammers (4) mounted between the discs (1) at intervals defined by the crosspieces (3) and spindles (5) for swingably mounting the hammers (4) and passing through the discs (1). A device (6) is provided for selectively individually locking the hammers (4) in a retracted position in the drum which drives the hammers (4), for releasing the hammers for outward swinging. The locking device is a fluid-actuated peg (7) insertable in and withdrawable from a hole (9) in each hammer.
