Title: Process and device for constricting the magnetic circuit of a rotating electric machine
Inventor: ALBAGNAC PASCAL
IPC: H02K15/02
Filed: 1989-05-30
Abstract: The invention relates to a process for constricting a magnetic circuit formed by a stack of plates clamped on each side by slabs held by ties with threaded ends, each end receiving an associated clamping nut. According to the invention, the threaded end of a tie is coupled up to an associated traction jack resting against the slab, the prestress in the tie is relaxed until a predetermined elongation is obtained, a shim is inserted under the clamping nut, then the traction applied to the tie by the jack is released; these steps are repeated in succession for each slab, this being possible even when access to the ends of the ties is very limited, both axially and laterally. The implementing device essentially includes a traction jack 100 which can be associated with each individual tie and coupled up to a threaded end of the latter, and measuring means 300 associated with the two ends of the said tie for determining its respective elongation and the compression of the magnetic circuit. Application in particular to the constricting of the stator circuits of hydro-electric power station alternators. The method is of very special interest when there is little room to operate and/or when the nut is welded to the tie.

Title: Non-reusable single-use plastic medical syringe. Device for neutralisation by twisting/breaking the shaft
Inventor: NOUR-EDDINE OMAROUAYACHE
IPC: A61M5/50
Filed: 1990-03-12
Abstract: Non-reusable single-use plastic medical syringe according to the invention in which the plunger must be extracted as far as possible before insertion for injection in order to make a column of lugs (1) pointing downwards which are provided on one face of the shaft, pass over a small bar (7) (forming a lug pointing upwards) fixed at one or two centimetres from the upper edge of the body of the syringe. This small bar forms part of a fixed upper part (FUP) (3). The plunger can then be lowered after rotation of the shaft through 180 DEG above the small bar, whilst the head which is integral with the shaft portion pressed against the bar, does not rotate. In return for this rotational movement which brings a smooth face of the shaft above the small bar, this shaft is broken in a highly weakened part which is then located just above the upper edge of the small bar. The shaft of the plunger and the body of the syringe are provided with a large pre-cutout causing destruction of the syringe during any wrongful manipulation.

Title: Microvision device with microcamera
Inventor: PATRICK FOULGOC
IPC: H04N3/06
Filed: 1990-09-07
Abstract: The invention relates to a video device with a monitor specific to a camera capable of being miniaturised to a great extent. In the camera, the straight-line vibration (7) of an optical fibre (12) is accumulated with a rotation (8) in order to cause this fibre to observe a whole surface, a lens focusing the image onto the said optical fibre. Provision is made for marking the amplitude of the vibration and the speed of the rotation of the camera so that the monitor imitates them in its scanning, the latter being therefore similar to the movement of the end of the optical fibre (12). The rotation here is brought about by that of a cable (10) linking the camera to the monitor, or by a motor situated in the camera. The vibration is provided by an electromagnet (2) or by a piezoelectric transducer supporting the optical fibre and making it possible to avoid marking its vibration by the precision of the latter.
