Abstract: A printer for printing a 3D object based on a computer model, the printer comprising a tool for extruding or solidifying material, a stage supporting layers of the object; motion structure defining the shape of the layers, and a controller configured to make a path to be followed for making the object. To increase at least one of the speed and the precision by which the object is made, the controller is configured to define the path by defining a plurality of line segments and by defining transition segment for insertion between the line segments. The controller is further configured to only demand material deposition along the line segments and not along the transition segments.

Abstract: Head of a string trimmer, the head being rotatably trained around a spinning axis, the head including a wall including at least one eyelet, at least one bearing, which is received in the at least one eyelet and which defines a rotation axis, and at least one sub-assembly including a blocking member, and a cutting string that is held by the blocking member so as to extend outward of the wall radially to the spinning axis when the head is trained in rotation around the spinning axis, the at least one sub-assembly being received by the at least one bearing so that the at least one sub-assembly is rotatable without restriction around the rotation axis of the at least one bearing with respect to the wall.

Abstract: This method of tightening a threaded fastener (6) to a predetermined torque comprises steps in which: axial and rotational coupling is begun, by surface shrinking to a tight fit, of the threaded fastener (6) to a tightening member (2) capable of turning the threaded fastener (6) and thereby tightening it, the tightening member (2) and the threaded fastener (6) being able, from an initial coupled configuration between the tightening member and the threaded fastener, to remain rotationally coupled at a rotary drive torque, transmitted by the tightening member to the threaded fastener, that is less than the predetermined tightening torque, and to be rotationally decoupled from each other at a rotary drive torque, transmitted by the tightening member to the threaded fastener, that is equal to the predetermined tightening torque; and from this initial coupled configuration, a rotary movement is applied to the tightening member (2) up to a rotary drive torque, transmitted by the tightening member (2) to the threade

Abstract: A process and machine for the continuous casting of thin steel products, in which the inner casting space (13) of the mold (1) is given a substantially spindle-shaped cross-section which forms a central part (17) of large thickness (L), making it possible to introduce a jet of molten metal under normal conditions, and having on its sides (18) a small thickness (1) corresponding to that of the product to be produced (53). In a thickness-reducing stand (2) directly at the exit of the mold (1), the central part (17) of the product is progressively flattened to a thickness (1) equal to that of the sides.

Abstract: A foliage trimmer has a housing centered on an axis, rotatable thereabout in a direction, and formed with a radially open eye. A spool rotatable in the housing carries a supply of a cutting line having a free end extending from the housing through the eye thereof. The spool has an outer periphery formed with at least one radially outwardly open recess or notch. A latching pawl has one end pivoted in the housing adjacent the eye about an axis parallel to the housing axis and an opposite end radially engageable in the notch and angularly offset from the pivoted end relative to the housing rotation direction. This element is displaceable as described above between an inner position with the opposite end in the notch to inhibit rotation of the spool and an outer position with the opposite end clear of the notch and the spool being rotatable. The line passes radially outward around the opposite end and radially inwardly engages same.

Abstract: The bracelet is constituted by members of general U shape (1 to 5), with the same internal profile, engaged in staggered manner one in the other, the sides (2a,5a) comprising, on their inner face, a groove (6a,7b) together defining a passage for a pin (10) of corresponding shape, in particular circular shape. The clearance (13,18) between two adjacent members of the same row is less than the necessary movement of the members perpendicular to the pins for releasing it from the pin and from the associated member. Means such as a head or stud are provided for retaining the members transversely with respect to the bracelet. The members may be of uniform thickness, the grooves being formed by the curvature of the sides of these members.

Abstract: A continuous casting ingot mould comprises spaced apart front and back plates between which are arranged two lateral plates. The front and back plates are mounted respectively on a movable frame and a stationary frame provided with means for supporting and clamping the side plates between the front and back plates, the supporting means including two articulations slideable axially along two columns fixed to the stationary frame and extending perpendicular thereto, one articulation being fixed to the movable frame and the other being mounted on the movable frame to slide relative thereto in a direction parallel to a line joining the axes of the columns and perpendicular thereto.

Abstract: An apparatus for adjusting the operating position of casting vessels during the continuous casting of metals, especially steel, the casting vessels being arranged at a pivotable transport mechanism. There is provided a drive for pivoting such transport mechanism and a locking device for the operating position. The locking device embodies mechanism for adjusting the casting vessel in different operating positions.
