  • Patent number: 5773604
    Abstract: The invention relates to a polyol composition exhibiting a very high heat stability and a very high chemical stability, characterized in that it exhibits an optical density lower than or equal to 0.100 in an S test. The invention also relates to a process for the preparation of such a composition, this process consisting in subjecting a polyol syrup to a stabilization stage such as a fermentation, an oxidation or a caramelization, and then to a purification stage. The invention also relates to the application of this composition to the manufacture of products using alkalis or undergoing a heat treatment at high temperature.

  • Patent number: 4668321
    Abstract: A packing device includes a series of identical vertically corrugated streaming sheets. Each streaming sheet includes, in succession, in a direction parallel to the crests of the corrugations, at least two regions, namely a region of corrugations having a first amplitude and a region of corrugations having a smaller amplitude, which are interconnected by a transition region. Each streaming sheet has an even number of regions of corrugations in phase opposition with respect to the adjacent region of corrugations and each streaming sheet has, in each transition region and in two longitudinal lateral regions, a series of bosses, having flat heads which project alternately from one side and the other of the streaming sheet in phase with the region of corrugations having the first amplitude which is adjacent and/or in phase opposition with respect to the adjacent region of corrugations of smaller amplitude.

  • Patent number: 4621250
    Abstract: A stationary case has a resistive track. An elastic wiper is carried by a rotor mounted to rotate in the case and able, during operation, to rub against the resistive track, and a spring is placed between the stationary case and the rotor to pull the rotor to a rest position. The case provides at least one housing able to receive the wiper without initial stress or deformation in an initial position of introduction of the rotor in the case and to allow the wiper to come in contact with the track during mounting of the rotor in the case by rotation of said rotor between its introduction position and its rest position. Application is to measuring the angular position of the throttle valve of an internal combustion engine.
