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 reel comprises a winding hub with a flange which presents, on the outside, a toothed ring for drive in rotation and, inside, a toothed track for immobilization, and which is provided with an overmoulded metal washer, the free edge of the hub further being centered and fixed on a second flange and the inner cavity of the hub containing a neutralizable brake normally maintained in engagement with the track and capable of being spaced apart therefrom by a pusher. The second flange comprises a coronal extension extending towards the center and imprisoning the brake in the cavity of the hub thus partially closed, brake whose axial neutralizing stroke is limited.

Abstract: A drawer of moulded synthetic plastics material is adapted to be equipped with an auxiliary locking device, preferably in the form of a box, which is located and fixed within a front housing of the drawer. This auxiliary locking device comprises a lock provided with a bolt, and it is provided with projecting parts engaging and locking automatically inside cut-outs provided for this purpose in the housing of the drawer.

Abstract: A ring for sealing and storage, a spool of recording tape comprising a band of flexible and extensible matter intended for surrounding a spool and equipped with a hook and a loop for closure and tension. The band, the loop and its link for hingeing onto the band, are all in one piece, the hingeing of the link being ensured by zones of reduced thickness. The whole is moulded on the flat, since when the link is made to pivot backwards the first time, being equipped with ramps it passes by a column by elastic deformation, a return of the link into the original position being then prevented so as to obtain a pre-hooking position of the loop.

Abstract: The invention relates to an improved platform for a camera or cine camera stand, wherein a dog gear wheel fast with the deck element cooperates with the corresponding gear wheel of the dog which is fast with a split sleeve which is mounted to slide on a shaft, fast with said deck element and free in the turret, is repelled, for mesh of the teeth of these gear wheels, by a spring abutting on a shouldered part of said shaft and is adapted to be clamped thereon by a control handle screwed in said split sleeve.

Abstract: The invention relates to a device for gripping a magnetic disk cartridge which comprises a pivot piece resting freely and selectively on the lid by one of its faces and by its rounded edge forming sliding pivot; each rod fast with the extractor plate presents in lateral projection a spindle located in a housing which is made in the pivot piece, opening in a slot and comprises an open end bearing for the spindle of the rod in question, the distance "D" being greater than the distance "d"; springs maintain the rod spindles elastically in said bearings .

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: The present invention relates to a platform which comprises a turret mounted to rotate about a vertical axis with respect to foldable legs and supporting a plate fast with a shaft mounted to rotate about a horizontal axis with respect to this turret, wherein the hand lever for controlling the swivelling of the plate is foldable against the folded legs and connected to its bearing element on the platform by means of a swivelling device with built-in locking system for at least two positions of this lever.

Abstract: The present invention relates to a tripod with adjustable support surface for supporting various objects, wherein the stand comprises a central support provided with pivot pins for telescopic legs adapted to pivot in radial planes. According to the invention, a selection ring is mounted to rotate about the vertical axis of the support, immobilised in axial translation and limited in amplitude of rotation in order to be able to occupy at least two angular positions and this ring bears at least two sets of three stop members cooperating with end stops of the legs, these sets being offset angularly in register with the positions of the ring and defining respectively at least two different inclinations of these legs. This tripod may be used for supporting photographic, cinematographic, or video shot taking apparatus, projection apparatus, geodesic measuring instruments, antennas for emitting or receiving radioelectric waves or the like.

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.
