Obtaining aqueous solutions of homo- and/or copolymers of ethylenically unsaturated monomers comprises using compounds containing a phosphorus atom with a degree of oxidation 5, in quantity of 0.005-0.49 mol. per mol. unsaturation, for polymerisation in presence of hydrogen peroxide and absence of all free radical decomposition agents and free radical generators. Also claimed are polymers obtained...

The invention discloses a new class of silicone surfactants and their use for the preparation of flexible urethane foam. The surfactants incorporate high molecular weight polyethers prepared with narrower molecular weight distributions than conventional polyethers. These polyethers are prepared using a double metal cyanide (DMC) catalyst. These surfactants are better foam stabilizers than the anal...

The system for orienting and guiding self-propelled vehicles comprises a plurality of inertia sensors (15,16,17) connected to an electronic computer to which the data relating to the route travelled by the said vehicle (15), such as the steering angle and the path length, is also sent. A multiple head (20) for occasional route detection communicates to the computer (12) the data relating to deviat...

' The run-flat tire of this invention includes a pair of bead regions, a crown region with a tread and a tread reinforcing package including a cap ply and self supporting sidewalls between each bead region and the crown region. An innerliner ply maintains air within the inflated tire. The self supporting sidewalls each include a first crescent-shaped reinforcing member, an inner carcass layer...

The invention relates to a method for resetting a processor, and a watchdog for generating a reset pulse to a processor which can initialize itself and which sends acknowledgement pulses at predetermined intervals to the watchdog comprising transmission means (5) for generating and transmitting reset pulses to the processor. The watchdog comprises counter means (7) for counting the number of reset...

A method and system for treating aneurysms by applying RF energy to collagen. A catheter is disposed near the aneurysm and collagen is exuded into or near the aneurysm. RF energy is applied, using the same catheter or a second catheter, to the collagen, causing the collagen to harden and cover the weak region of the blood vessel wall, and providing a base onto which epithelial cells of the blood v...

The present invention is a process of making strap using both post consumer and non-post consumer PET of wide distribution intrinsic viscosity (IV) through direct solid state polymerization in a non-peletized state to produce PET with an increased, heterogenous IV suitable for high performance strap extrusion. The process increases the IV of post-consumer resins, consisting principally of polyethy...
