Title: Dispenser for granular or pulverulent products with built-in flow rate control
Inventor: COUDERT PIERRE
IPC: A01C15/00
Filed: 1991-02-08
Abstract: The invention relates to a dispenser for granular or pulverulent products such as fertilisers, salt or sand comprising a reservoir-hopper (1) which allows the product to be spread to flow by means of a dosing device on a centrifugal dispensing system, comprising at least one turntable (2) driven with a rotational motion by a drive system. The centrifugal dispensing system ensures the projection of the product and the spreading of it on the ground and it comprises product flow means, which are disposed downstream of the dosing device, that is to say below that dosing device and in place of the centrifugal dispensing system with which these flow means constitute a single transversely mobile assembly which has two positions: an internal product-spreading working position and an external position for controlling the flow rate or emptying, in which the transverse kinematic chain is broken between the mobile assembly and the drive system by cutting out their connection means. Application: Agricultural machinery.

Title: Composite material reamer - has groove in side surface of cutting edge which displaces cuttings radially
Inventor: ALAIN GAIRAUD
IPC: B23D77/00
Filed: 1992-04-17
Abstract: The cylindrical lateral surface of the reamer ends in an attack surface which has a cutting wall (12). The cutting edge advancing surface (9)  is turned in the direction of reamer rotation and radially displaces cuttings separated by the cutting edge. The  surface (9) has a side with a groove whose bottom is assembled so that the radial component of the force from the cutting is strong enough to overcome the opposing centrifugal force resulting from reamer rotation. The reamer advances downwards and the reamer wall (12) makes an angle with the direction of advance such that the bottom of the enlarged part of the hole created by the reamer forms a funnel towards the previously drilled hole  so that gravity adds its effect to that of the advancing surface. ADVANTAGE  -  Reduces the jamming of cuttings between the reamer and neighbouring material.

Title: Procédé pour débiter un objet portatif d'une pluralité de montants, objet portatif, dispositif de transfert et application correspondants.
Inventor: FRANCOIS GRIEU
IPC: G07F7/02
Filed: 1992-04-17
Abstract: Le domaine de l'invention est celui des transactions, et par exemple du paiement de biens ou de services, entre au moins un dispositif de transfert et au moins un objet portatif. L'objectif de l'invention est de fournir un procédé de transaction optimisant la ressource mémoire d'un objet portatif, ou, en d'autres termes, permettant de minimiser le nombre d'éléments binaires nécessaires pour chaque débit. Selon l'invention, on ne programme pas autant d'éléments binaires de la mémoire de l'objet portatif qu'il y a d'unités à débiter. En effet, les éléments binaires ne sont plus considérés indépendamment, mais par champs. On fait appel à un code spécifique, permettant de coder dans chaque champ un nombre de valeurs unitaires supérieur au nombre d'éléments binaires composant ce champ. Avantageusement, chacun des montants à débiter est supérieur ou égal à un montant minimal Ml prédéterminé strictement supérieur à 1.

Title: Recognition procedure for authenticated articles
Inventor: OSCAR LOSSO
IPC: G06F21/86
Filed: 1993-12-09
Abstract: The procedure consists of recognising a code held in a logical cell forming part of the object, using a key which is known only to the owner of the object. The cell is contained in an inviolable box (30) which contains an EPROM and a RAM, the latter being enclosed in a winding of conductor wires embedded in polyester resin which act as a feed for an external and remote power source. The code contained in the cell can be revealed only by the owner of the code key, i.e. the owner of the object, and any attempt to open the box will result in a destruction of the code.
