Patent FR-2603795-A1 (FR)
IPC: A61C13/225
Filed: 1986-09-15
Abstract: A removable dental prosthesis is magnetically secured to an anchor face of a ferromagnetic body implanted in a jaw by an attachment system comprising a saliva-resistant cushioning mass secured in the prosthesis and forming a pocket open toward the anchor face, a ferromagnetic and saliva-resistant shell seated in the pocket and open toward the face, a permanent magnet fixed in the shell and having a magnet face confronting the anchor face, and a permanently magnetized plate having a rear face directly contacting the magnet face, a front face directly confronting the anchor face, and an outer periphery. The plate is of a material not corrosible by saliva and is magnetically polarized like the magnet which itself is of relatively great strength and of a material corrosible by saliva. The outer periphery of the plate is sealed to the shell so as to encapsulate the magnet in the shell with the plate and thereby protect it from corrosion. With this system the flux of the magnet passes substantially entirely via the plate to the anchor body when the front and anchor plates are closely juxtaposed.

Title: Additive cross-country ski-binding device facilitating performance of the skating step
IPC: A63C9/00
Filed: 1986-12-08
Abstract: Device for facilitating performance of the skating step in Nordic cross-country skiing. The invention relates to a device making it possible to raise the heel of the boot, to separate the heel of the boot from the rear of the ski and to immobilise the oscillation of the ski in its return phase, carrying out a skating step. It consists of an angle piece 1 having orifices 2 allowing the passage of a guide rod 3 comprising a spring 4. When the user relaxes his pressure on the ski at the end of the thrusting movement, the spring 4, compressed under the heel 8 between the shaft 5 and the orifice 2, relaxes, moving away the rear of the ski 14. The movement is immobilised by the screw 6 against the orifice 2. The device according to the invention is intended particularly for facilitating performance of the skating step in Nordic cross-country skiing.

Title: Method of personalising documents preventing their fraudulent use
IPC: G09F3/02
Filed: 1987-02-09
Abstract: The present invention makes it possible to personalise a document, and particularly a chequebook, with the image of its owner so as to avoid it being used by an unauthorised person, when it has been lost or stolen. The process consists of a self-adhesive figure on which is reproduced a photograph of the person authorised to use the chequebook. If such figures have previously been bonded to each of the cheques of the chequebook by its owner, the payee may, at the moment of the payment, check that the identity of the issuer really does conform to the photograph which he has in front of him. Moreover, the banks can send out cheques specially designed to accommodate such figures either optionally or compulsarily, for the cheque to be validated. The process is particularly intended to protect cheques against fraudulent use following the loss or the theft of the chequebook.

Title: Interchangeable pick-up for electric guitar
IPC: G10H3/18
Filed: 1987-06-12
Abstract: Interchangeable pick-up 17 for electric guitar, characterised in that it slides over bars 2 provided for this purpose in the body 1 of the guitar. It is then possible at any instant to change the type of pick-up for changing the sound (rock, jazz, bass, treble, etc.) by a single hand action and without any tool. The electrical contacts are made when the bolts 20 for fastening the pick-up 17 onto the support plate 19 touch the contact plates 6 housed in the notch 3. One of the plates 6 is connected to the potentiometer 11 by a conducting electrical wire 8, and the other plate 6 is connected to the bridge 12 by the electric wire 9. The electric wires 21 for terminating the winding 28 of the pick-up 17 are each connected to a bolt 20. The electrical microcircuit circuit of the guitar is thus closed.
