This invention has the ambition to have solved the serious problem: it pulls down the volume of wastes in the place of production by bringing it back to the originary volume; it recovers the expanded polystyrene, dissolved in solution with the technique of flotation; it makes it useful for the production of plastic manufactured goods as binder and other uses.

A method for producing an elastomeric mixture based on the steps of mixing the additives and/or fillers of the predetermined composition of the mixture to be produced into a solution of at least one elastomer in one or more solvents, removing the solvent from the mixture thus obtained, and granulating the mixture to produce dry granules of elastomeric mixture.

When the user (1) of a communication network (7) has identified a product or service of interest, he issues an order for the supply of the product/service by inputting into the network his particulars, including a respective code identifying his connection to the network manager (3). The sales manager (7) sends a request to the network manager (3) to check that the identification actually correspo...

Parties negotiate using an electronic network, such as the world wide web. A set of hypotheses describing the negotiation is generated, either at a central location or by one of the parties. The hypotheses are each associated with a confidence value. For example, the hypotheses may describe the types of parties negotiating, or their objectives. The negotiation can then be controlled using the conf...

Auxiliary components on electronic card assemblies, such as batteries, jumper plugs, crystal spacers, sockets and heatsinks which do not appear on a design schematic are specified in a card assembly design file 102 by assigning, at the design schematic level, attributes to control the addition of auxiliary components. Bill of Materials 106 and Component Placement Lists 110 are extracted from the c...

A phenolic foam including a phenol formaldehyde resin and a blowing agent has an amount of boric acid which is greater than 35 and ideally about 60 parts by weight of the resin. The foam includes acid catalyst(s) and surfactant(s). The addition of boric acid enhances the temperature characteristics of the foam.

When an oil well has been completed it is necessary to monitor downhole the rate at which the well's products are flowing along the borehole and up to the surface. One type of method and apparatus previously proposed for this purpose in wells with a horizontal borehole section, where the fluid is stratified into distinct component layers, involves the use of tracer or maker materials, employing an...

A gearshift control system comprises an electrical control unit (1) which operates hydraulic valves (14) controlling a hydraulic gearshift actuator. The vehicle in which the system operates has a dashboard control (5) to preselect a gear change, which is actuated by depressing the clutch pedal (3) operating a switch (2), both the switch (2) and control (5) being connected to the unit (1). The syst...

Trans-1,4-polybutadiene is heated to a temperature above about 104 F (40 C), at which it can be readily processed, without causing oxidative gelation, by exposing it to electromagnetic radiation having a frequency in the range of about 2 MHz to about 80 MHz, the trans-1,4-polybutadiene being oil-extended with at least 10 phr of a processing oil. The heated trans-1,4-polybutadiene is mixed with a r...

An expanded, memory molded, increased density, highly impact-resistant polystyrene construct, and method of making the construct. The construct is formed by molding pre-expanded non-equilibrated polystyrene beads to a first volume, cooling rapidly, and then compression molding to a final, smaller volume. The resultant constructs have increased density, and high impact strength without increase in ...

A spring brake actuator (14) includes a housing having first (51) and second (52) housing sections defining a housing interior (53). A support plate (70) is movable between retracted and extended positions relative to the housing and a spring (72) is disposed between the second housing section and a first surface of the support plate for biaising the support plate to the extended position. An actu...
