Patent number: 5712958Abstract: An analog type fuzzy logic controller is adapted to permit the implementation of a set of rules. The controller includes a circuit (B,C) for determining the overall degree of truth of each rule and a circuit (D,E) for determining the values to be supplied at the output. The determination circuit of the overall degrees of truth of the various rules is composed of a network (C) of interconnected resistive elements. Each of the resistive elements is associated with a condition of a rule and is adapted to be commanded in such a way that its conductance is substantially proportional to the degree of truth of the associated condition. The current intensities circulating in the various branches (21,22,23) of the network are representative of the overall degrees of truth of the various rules.Type: GrantFiled: September 22, 1995Date of Patent: January 27, 1998Assignee: CSEM Centre Suisse d 'Electronique et de Microtechnique SA - Recherche et DeveloppementInventor: Olivier Landolt

Patent number: 5693188Abstract: Apparatus for the thermal conversion of solids containing hydrocarbons. In one embodiment for solids which can be converted entirely to vapour, pieces of the solids are continually fed into a molten lead bath in an oxygen free atmosphere in an elongated conversion chamber. An auger partially immersed in the lead bath carries the floating pieces along in the molten lead bath until they are gradually converted to hydrocarbon vapour which rises upwardly to a condenser. In another embodiment for solids which can be converted to a vapour, particulate matter and residual solids, the lead bath extends further into a separation chamber with an inclined retaining skirt extending between the conversion chamber and the separation chamber, The auger forces the particulate matter and residual solids remaining after vaporization down under the inclined skirt, but the hydrocarbon vapour is prevented from escaping into the separation chamber.Type: GrantFiled: November 8, 1996Date of Patent: December 2, 1997Assignee: Unique Tire Recycling (Canada) Inc.Inventors: James R.
