Abstract: An electronic unit suitable for being positioned on an internal face of a tread of a tire with a view to measuring operating parameters of a vehicle wheel equipped with the tire. The electronic unit includes: a body, configured to be embedded into the thickness of the tire, in a housing provided for this purpose, and includes sensors dedicated to measuring operating parameters of the wheel, a head, arranged at one end of the body, including a circuit board for managing information output from the sensors of the body and a way of communicating with a central unit installed in the vehicle; a way for connecting the elements with which the body is equipped and the elements with which the head is equipped; and a way to supply the electronic unit with power.

Abstract: The subject of the present invention is an electronic unit (1) suitable for being positioned on an inner surface (Fi) of a tread of a tire (P) with a view to measuring operating parameters of a vehicle wheel fitted with said tire, the electronic unit being characterized in that it comprises: a body (2) configured to be embedded within the thickness of said tire, in a housing provided for this purpose, and including sensors (4) for measuring operating parameters of the wheel; a a head (3), arranged at one end of the body and comprising a circuit board (5) for managing information from the sensors on the body and communication means (6) for communicating with a central unit on board the vehicle; connection means (8) for connecting the elements fitted to the body to the elements fitted to the head; and a means (7) for supplying the electronic unit with power.

Abstract: A device according to the invention for performing vibration measurements on a test part that has a rotor, especially a transmission, includes a base structure, on which a fastening device for the test part is arranged, and a vibration measuring device for measuring vibrations caused by a rotation of the rotor of the test part. According to the invention, a balancing device is provided, arranged on the base structure or at least partially integrated into the base structure, for identifying and/or eliminating an imbalance in the rotor. The device of the invention thus enables both a balancing of the rotor and the performance of vibration measurements on the rotor, using a single device.

Abstract: Vehicle wheel includes a rim and a pneumatic tire which includes a tread, two side walls, a carcass, reinforcing elements, and two tire beads with bead cores. An emergency running support body is supported on the rim which is arranged to support one of the pneumatic tire and an interior of the tread in an event of an emergency condition. The emergency running support body includes a shell-shaped ring body located inside the pneumatic tire and an emergency running surface on its exterior. At least one container, which contains a lubricant, is positioned inside a first ring chamber. This Abstract is not intended to define the invention disclosed in the specification , nor intended to limit the scope of the invention in any way.

Abstract: A powdered detergent suitable for use in home laundry machines contains (1) an acid component which provides an initial wash solution with a pH of 1-4 and (2) a coated alkali-supplying substance which neutralizes the acid wash solution within a period of about 2 to 25 minutes. The compositions may be free of phosphates and avoid the problem of ash build-up on fabrics usually caused by carbonate-based non-phosphate detergents.

Abstract: A method for washing textile material including first prewashing the textile material in an acid wash solution having a pH below 6.5 whereby incrustations remaining on the textile material formed in a previous main wash cycle are dissolved in the prewash cycle and then washing the material in a main wash cycle with a phosphate-free alkaline liquor whereby incrustations form on the textile material for removal during a second prewash cycle. The prewashing may be accomplished for 1-3 minutes at a temperature of 40.degree. C. while the main washing may be accomplished for the usual time at boiling temperature.
