Abstract: The invention concerns a panel comprising a front plate exposed to solar radiation and whereof the rear face is adjacent to an insulating layer, for example made of a synthetic foam. A conduit network for heat transferring fluid is inserted between the front plate and the insulating layer. A conducting lap such a fine and flexible aluminum grille is also inserted between the front plate and the heat insulating layer to collect the heat generated in the front plate and conduct it towards the conduit network. The invention is useful for collecting solar energy in the form of heat particularly in roofs.

Abstract: A roof movable between a raised position in which it forms a shelter over a terrace and a lowered position in which it forms a cover over a swimming pool. The roof is mounted on pivotable pillars via hinges. One edge of the roof is supported in the raised position by a winch and cable device for moving the roof assembly between the two positions.

Abstract: An improved roll-on, roll-off handling device is provided to lift one end of a container and to maintain it in the raised position during handling and displacement of the container, the device comprising a chassis; a wheel system for supporting the chassis upon the ground, the wheel system permits pivotal movement of the chassis with respect to the ground about a first axis parallel to the ground, the chassis pivoting about the first axis from a tilted position in which a first end of the chassis is adjacent to the ground and a raised position in which the first end is spaced from the ground; a carriage mounted on the chassis and displaceable along the longitudinal axis of the chassis, the longitudinal axis being transverse to the first axis; an apron removably attachable to one face of a container, the apron being connected to the carriage and adapted for pivotal movement with respect to both the carriage and the chassis about a second axis substantially parallel to the first axis; a connecting rod for pivot

Abstract: An improved roll-on, roll-off handling device is provided adapted to lift one end of a container and to maintain it in the raised position during handling and displacement of the container, said device comprising a chassis; a wheel system for supporting the chassis upon the ground; a carriage mounted on said chassis and displaceable along the longitudinal axis of said chassis; an apron removably attachable to one face of a container; a jack for pivotally displacing said apron with respect to said chassis and for moving said carriage and said chassis with respect to each other along the longitudinal axis of said chassis, whereby a container can move from a position in which said container rests on the ground with the chassis in a tilted position to a raised position in which said end of the container is raised and overlies part of the chassis.
