Polymers are prepared using dienyllithium initiators, a reaction product of organolithium with a 1,4-diolefin, to polymerize olefinically unsaturated monomers such as conjugated dienes under solution polymerization conditions to provide unsaturated polymers, branched polymers, graft polymers, polymers prepared by sequential polymerization, and coupled polymers.

In a method for plasma-initiated polymerization by the steps of exposing a vapor phase containing monomer vapor to a plasma and introducing a polymerization initiating active seed consequently produced into a condensate phase of monomer thereby effecting chain-growth polymerization of the monomer, the improvement which comprises effecting the production of the polymer while keeping a radical polymerization initiator present at least in the aforementioned vapor phase.

A patient-initiated response device and method for re-educating debilitated muscle tissue. The method comprises the detection of an electromyographic signal in a muscle group, which is used to trigger an artificial stimulation signal of a higher pre-determined intensity and transmit such a signal to a debilitated muscle group. The patient-initiated electromyographic signal may be detected in a debilitated or non-debilitated muscle group. The device detects an electromyographic signal of a pre-de...

A precussion initiated spotting charge in which the spotting charge is caed by the front end of a solid propellant rocket and has a priming charge which is specifically mounted in a forward section of the housing for the spotting charge in a lead support structure with a strengthening outer structure for supporting the lead structure relative to the spotting charge body structure.

Grafted polymer particles are prepared by a free-radical addition polymerization mechanism using a flame produced by igniting a mixture of a combustible gas and an oxidant to heat at least a portion of the surface of a solid polymer particle to produce free-radicals thereon. At least one polymerizable ethylenically unsaturated monomer is contacted and reacted with the free-radicals formed on the surface of the polymer to form a graft thereon.

A percussion initiated inflator assembly for an airbag comprises a detonator panel that effects essentially simultaneous ignition of a plurality of gas generators by a shock wave.

Compositions comprising a free radical sensitive compound and a thermally stable substituted diazene which upon exposure to electromagnetic radiation is convertible to a thermally unstable substituted diazene may be formed and processed utilizing thermally intense techniques and thereafter the free radically initiated changes initiated by exposing the substituted diazene to light and heat.

An ionized gas plasma is established in an electrical field in contact with a non-vapor volume of monomer (liquid and/or solid). The plasma creates active polymerization sites in the monomer volume to initiate propagation of polymerization therein. After initiation, the partially-polymerized monomer volume is postpolymerized in the absence of the ionized gas plasma to yield a very high molecular weight polymer which may be essentially free of cross-linking in desirable forms including commercial...

A method for workflow processing of objects stored in the memory of a computer system in accordance with the invention includes storing an object, which is to be processed, in the memory of a computer system; reading the object, which is to be processed, from the memory, and adding a graphical symbol to the object; processing the graphical symbol with middleware; and in response to the processing of the graphical symbol with the middleware initiating actions to process the object in accordance w...

For dispensing to a respiratory patient single discharges of metered aerosol medication, a conventional aerosol container designed to deliver in response to a single actuation a metered amount of aerosol compound, is combined with a chamber partly formed by a breath-operated membrane linked with a spring-retained catch and latch actuator which on release by the inhalation-deflected membrane presses on the metering valve of the container delivering a single discharge in exactly timed relation wit...
