Title: Cable coiling box
Inventor: BLANCHET PIERRE
IPC: G02B6/44
Filed: 1984-06-27
Abstract: This cable coiling box has a flat shape. It includes a bottom 24 and a lid 25 which are demountable. A cable housing 28 of annular shape with two points of access 29, 30, has a hollowed-out impression inside the bottom 24. Its outer periphery has the shape of an upside down capital omega 3 closed by a vault (roof) 32 whose ends face the feet of the capital omega and define, together with the latter, the points of cable access 29, 30. Its internal periphery 33 is circular and off-centred towards the base of the capital omega in order to make available, by simple traction on the cable, the greatest part of the length play left to a turn by the width of the annular housing 28. It is used advantageously in fibre-optic transmission frames (cases) for facilitating modifications to the distribution of the fibre-optic bundles of a cable between the various equipment levels.

Title: Device for linking between a boot and a cross-country ski
Inventor: PROVENCE MARC
IPC: A63C9/20
Filed: 1985-11-26
Abstract: The invention relates to a device for linking between a boot 22 and a cross-country ski 12, comprising a bending blade 14 made from an elastically deformable material permitting pivoting of the boot about a horizontal axis transverse to the ski. According to the invention, in the absence of external stresses, the rear region of the bending blade is inclined upwards and rearwards at an angle alpha of between 5 and 45 DEG . During skiing, as soon as external stresses separate the blade from this position of balance, a return moment is exerted due to the elasticity of the said blade, which tends to re-assume its position of balance. This device is advantageous in that the skier avoids a certain number of superfluous forces. The invention also relates to different embodiments in which the same advantages are achieved.
