Title: Safety valve for oil wells particularly intended to be inserted in a receptacle sleeve with no stop shoulder.
Inventor: JACOB JEAN-LUC
IPC: E21B23/02
Filed: 1988-07-29
Abstract: The invention relates to a safety valve for oil wells intended to be inserted in a receptacle sleeve with no stop shoulder. This valve comprises a system of anchoring in the receptacle sleeve which is characterised by the presence of a peripheral socket 401 adapted to clamp the anchoring dogs 54 in a low position and, on the contrary, to release the latter, in a high position, by means of windows which it comprises. During the lowering of the valve in the receptacle sleeve, this ring bears against the machining clearance 1d of the said sleeve and moves from its low position towards its high position releasing the dogs 54 which penetrate into the anchoring groove 1b under the effect of spring rods 402. The invention is applicable both in the case of a well functioning by natural flow due solely to the pressure of the effluents and in the case of a well functioning by artificial flow due to the injection of a fluid under pressure.

Patent FR-2641942-A1 (FR)
Title: Orthopaedic smithery plate for a horse's hoof
IPC: A01L7/02
Filed: 1989-01-24
Abstract: The invention relates to an orthopaedic smithery plate for a horse's hoof, which will in particular find its application in the field of equestrian sports and racing disciplines. Experimental studies have shown that mechanical stresses encountered at the hoof can be broken down into an initial high-amplitude vibrational phenomenon with frequencies from 0 to 200 Hz, caused by the impact of the hoof on the ground, and an inertial force of the mass of the body supported and propelled by the muscle organs of the supporting limb. The invention is in the form of a plate 5 which is interposed between the shoe 3 and the hoof 2 of the foot 1 of the horse, in order both to absorb the impact vibrations and reduce the maximum amplitude of the force with which the hoof bears on the ground. For this purpose, the plate 5 comprises a shock-absorbing elastomer pad made from an elastomer material which absorbs impact energy and is resistant to abrasion and tearing. The invention relates to equestrian sports disciplines.

Title: Automatic control device for swinging wing
Inventor: GUY PALLANCA
IPC: E05F15/04
Filed: 1990-02-09
Abstract: The present invention relates to a device for automatic control of a swinging wing.
