The roof system has mechanisms for causing the two sets of auxiliary arms to pivot in one direction or the other in order to open or close the roof system, and the two auxiliary arms in a given set are arranged in such a manner as to be situated transversely on the outside of the roof panels.

Abstract: The invention concerns a folding roof comprising a front element and a rear element, the two elements capable of being stored in the vehicle boot, and locks for locking together the front edge of the front element to the front element of the vehicle body and the rear edge of the front element to the front edge of the rear elemen. The locks are actuated by rotating rods connected to a motor. The rotating rods and the locks are arranged such that the rotation of the motor causes the control rods to rotate simultaneously and the locks to be engaged when the roof covers the vehicle.

Abstract: A metal bridge includes at least two longitudinal girders connected by a plurality of transversal spacers and on which rests a platform. Each longitudinal girder is built by butt-jointing a number of prefabricated metal elements in the form of tubular hollow coffers of polygonal transversal section, each extending over a length compatible with transport and lifting devices. At least certain coffers of two neighboring girders are connected in twos by a plurality of spacers, each composed of a metal tube.

Abstract: The invention concerns a rollbar integral with the vehicle body and mobile between a retracted position and a position wherein, when the roof is open, the rollbar projects sufficiently above the vehicle back shelf to protect the passengers in case the vehicle overturns. The rollbar consists of two rollbar elements mutually articulated at the top of the rollbar, the lower ends of each rollbar element capable of sliding along a straight line parallel to the vehicle back shelf and located beneath the shelf.

Abstract: A centrifuge partition chromatography device for separating a liquid into at least two phases, comprising at least one flat ring (3a) that can be rotationally driven around its axis, disposed in a substantially vertical position. Said ring (3a) comprises a plurality of cells (7) whose dimensions are greater in a first direction than the dimensions in a second direction which is substantially perpendicular to the first, disposed side by side and distributed along the periphery of said ring (3a) in addition to being connected to each other in a series by inlet and outlet ducts (15) terminating in the opposite respective ends of each cells (7) enabling the circulation of liquid. The invention is characterized in that said ducts (15) are disposed in such a way that the liquid supply jet penetrates the cells (7) in a direction that includes at least one radial component relative to the axis of rotation of said ring (3a).

Abstract: The invention relates to a conduit for circulation of fluid comprising a sealed pipe (A) fixed to a rigid supporting body (B) comprising a horizontal base having a lower face bearing on a laying surface (C) and two lateral wings going up vertically along the sites of the lower section of the pipe (A), said supporting body (B) comprising, on either side of the tubular enclosure (A), a single-piece portion (31, 31′) having, as a transversal section, a L-shaped profile comprising a substantially vertical branch (32) forming the wing extending along the corresponding side of the enclosure (A) and a substantially horizontal branch (33) extending beneath the former in order to form at least a portion of the base (3) of the supporting body (B) resting on the ground (C).

Abstract: A modular block wall includes dry cast, unreinforced modular wall blocks with anchor type, or frictional type or composite type soil stabilizing elements recessed therein and attached thereto by vertical rods which also connect the blocks together. The soil stabilizing elements are positioned in counterbores or slots in the blocks and project into the compacted soil behind the courses of modular wall blocks. Alternative stabilizing element designs may be used with the modular wall blocks and other types of facing elements in a mechanically stabilized earth structure.

Abstract: This invention is a side wheel attachment for removably attaching an auxiliary side wheel to a bicycle. The side wheel attachment comprises a single structural rod which is folded in the desired shape, i.e. forms a helical torsion spring. In natural unbiased condition, the first and second ends of the spring rod extend generally perpendicularly to one another. The first end of the spring is inversely U-shaped and tangentially engages by its web the rear axle of the bicycle where it can be fixed after adjusting its vertical position relative to the bicycle. The second end of the spring rod is rotatably engaged by the auxiliary side wheel, therefore acting as its axle. Both ends can angularly move relative to one another due to the helical spring. Therefore, in use, both auxiliary side wheels (installed on one side and the other of the rear bicycle wheel) and the rear bicycle wheel loaded by a bicycle rider, always stay in contact with the ground so as to accomplish their respective tasks.
