Abstract: A supporting device which is adjustable for height in order to adapt ski bindings to the thickness of ski-boot soles comprises a control member guided for longitudinal sliding motion within a stationarily fixed base plate. The control member cooperates with a support plate by means of stair-step surfaces having inclined risers. The longitudinal displacement of the control member produces a vertical displacement of the support plate by wedge effect.

Abstract: The toe abutment member comprises a jaw unit pivotally mounted on the ski and consisting of two lateral arms adapted to cooperate with the front portion of the ski boot in order to maintain the boot in the axis of the ski, and a resilient device housed within the body of the abutment member for locking the arms in the boot-retaining position with a predetermined stiffness of release. The toe abutment member essentially comprises in addition a feeler member placed in contact with the front portion of the ski boot and adapted to cooperate with the resilient device to reduce the stiffness of release at the time of a forward-fall position and/or when an axial thrust is exerted on the ski boot.

Abstract: The casing is made up of a number of identical compartments of prismatic shape in which are placed vertically either one or a number of fuel element bundles which are not secured to the casing, the casing walls being provided with means for guiding control rods, supplying emergency coolant and positioning measuring devices. At least some of the casing walls are constituted by two parallel thin metal sheets welded at intervals to stiffening webs which extend between the two metal sheets to the full height of the casing and parallel to the axis of the reactor.

Abstract: In a pressurized-water reactor (PWR), the top flange of the pressure vessel is penetrated by nozzles connected to vertical primary heat-exchangers which are located outside the vessel and above the level of connection. The heat exchangers and the primary circulating pumps are so arranged as to leave a free and unobstructed area above the reactor closure head, thus facilitating refuelling operations as well as remedial work on both pumps and heat exchangers in the event of a fault condition.
