Patent FR-2281211-A1 (FR)
Title: Mechanisms for folding tubular film to obtain concentric overlays - for automatic prodn of extensible tubular wrapping
IPC: B29C53/08
Filed: 1974-08-06
Abstract: Equipment for transverse folding of continuous tubular flexible film to produce an envelope comprises >=1 concentric layers of tubing of any required length. The mouth of the tubing is led down over a mandrel which keeps the mouth open. Travelling clamps grip the tube surface at a level corresponding to twice the height of the required envelope and carry the gripped zone down to the vicinity of the mouth of the tubing. The clamps release the film surface and, if necessary, return to grip and carry down a further layer of film. The mandrel has a bulbous profile to cause the internal fold to progress smoothly. When the required series of overlaid layers is complete, the envelope is cut off and removed from the mandrel. The device is used for the mfr. of short film packs which may be gripped by one extremity and extended to cover goods previously positioned on a zone to be enclosed by the extuded pack. The film gripping and manipulation systems are effective and reliable for semi-automatic operation. The parck is removed for transport and storage flat, instead of remaining supported on a disposable mandrel.

Title: Rotating shaft seal with double sided rubbing ring - has second O-ring to give further period of service when first is abrasively worn
IPC: F16J15/34
Filed: 1976-07-02
Abstract: The seal for a rotating shaft has a rotating ring (1) attached to the shaft by dowels in a ring (8). An O-ring seal (7) prevents leakage between ring (1) and shaft.

Title: Gravel prepn. for bituminous concrete mfr. - by dry grinding in a depression, while removing dust particles
IPC: E01C7/18
Filed: 1976-07-19
Abstract: Bitmunious material for road construction is made by heat-heating gravel and sand free of bitumen in a drying drum, and intimately mixing this with bituminous concrete in a mixer. The gravel used is practically dry large grain gravel which is subdivided while dry and while evacuating dust formed so as to produce granulometric fractions of desired sizes. The gravel fractions are then heated with the dried sand in a drying drum for >=3 (>=5) mins at >=100 (>=150) degrees C. and finally mixed with hit bitumen or bituminous concrete at is approx. 150 degrees C. A large saving of energy is obtd. compared with prior art, e.g. a saving of 30-40% of fuel oil, while the quality and hardness of the gravel are improved.

Title: Automatic locking stalls for animals - ensure that animal inserting its head locks stall on itself and opens next stall for another animal
IPC: A01K1/06
Filed: 1977-03-04
Abstract: The stalls comprise a framework of bars (2, 3, 4) and panels (5 to 8). Each panel has its upper left corner cut away as shown and a bar is pivotally mounted on each panel as at (9). When the bar is inclined and lies along the relieved side a space (13) is defined. The width of space (13') is sufficient to allow an animal to insert its head. When the animal lowers its head to feed its neck causes the bar to swing into a vertical position, in which it locks. The width of the gap between bar and frame is now insufficient to allow the animal to withdraw its head, consequently the animal is locked in. The locking action causes the bar of the next stall to incline permitting a beast to enter its head, and so on in succession. Manual unlocking is required to release the beasts.
