Abstract: A box for the storage, display and selection of diskettes or other magnetic members comprising a body defined by a base, a pair of side walls, a back part and a back upper part, together defining a receptacle for receiving diskettes or other magnetic members. The box is provided with a lid including a front upper part, a pair of side walls and a frontal part. The back upper part of the body and the front upper part of the lid are joined together by a continuous integral hinge. The side walls of the body and the of the lid are in mutual overlapping relation. The lid is adapted to be held in an open position by resting the lid on the body such that, in the open position, the lid is tilted back to form an obtuse angle with respect to the base of the body or the upper edges of its side walls.

Abstract: The case consists of a box 1 integrally molded with a retaining member 2 joined to the box 1 by a portion 8 of reduced thickness which forms a hinge, and of a lid 3 pivoted about an axis 16 on the box 1. The face 12 of the lid has an interruption such that is can pivot through an angle greater than 270.degree. on the box in order to form a support for the latter in the inclined open position. The turning movement of the retaining member is limited by a slot or aperture 18 in which is engaged a pin 16 which may at the same time be the articulation axis of the lid.

Abstract: The invention relates to a video cassette comprising two spools with single disk, the respective hubs of which spools are rotatably mounted with the minimum distance possible between their axes of rotation, inside a casing in two parts, so that the said disks partly overlap in projection and are contiguous respectively to the bases of the said casing parts, each base being provided, opposite the disk which it does not touch, with at least one zone projecting in extra thickness from the base in question so that its fixed guiding surface for the magnetic tape extends in the same plane as the internal annular face of the adjacent rotary disk, the said surface being anti-abrasive and entirely slippery, cassette wherein each of said zones is constituted by an independent part molded in self-lubricating and anti-abrasive plastic material, the said part being added on to the corresponding base of the casing and being fixed thereon by non-deformable securing means.

Abstract: The present invention relates to a maneuvering and release device for camera, wherein a connecting piece is mounted to rotate about the rod near the handle and is adapted to be locked on the latter in any angular position from all the possible positions, and this connecting piece also forms a sheath for the assembly of the fixed sleeve of the push button controlling a release, this sheath extending at right angles to the rod. An axial assembly of this release is also possible due to the alignment of a channel in the handle with a hole in the connecting piece. The device of the invention is more particularly applicable to the aiming maneuver of a camera and to the release of the shutter.

Abstract: This case-type storage box for sound and/or video recording tape or film wound on a spool or core comprises at least one resilient arm provided with a projection comprising inclined ramps so that when the spool or the like is introduced into the box the arm is caused to deflect and, when the spool is in its home position, to subsequently resume its normal position in which ribs formed on the arm engage the spool core aperture.

Abstract: A reel for the magnetic tape of a computer, wherein the central part is constituted, like the side flanges, by polystyrene, which is therefore ultrasonically weldable, and these flanges are welded on said part at four spots, the ring integral with the rest of the part being connected to the web by a plurality of ribs separated from one another by spaces.

Abstract: A set of weighing scales comprising a moving part able to move vertically relative to a fixed part and serving to support the load against the action of an elastic balancing device.Its guidance device comprises at least three sets of roller trains extending in radial planes passing through the guidance axis, whereby each roller is mounted loosely on one of the parts in such a way that there is a clearance between its tread and the other part. This guidance device cooperates with at least one anti-gyratory roller extending in a tangential plane and which mounted on loosely mounted on one of the parts and which is positoned with a clearance between the two vertical members of the other part. Its indicating device is of the floating type.
