20120328270 | Explosion Proof Forced Air Electric Heater - An explosion proof forced air electric heater is designed to supply heat to hazardous areas where the atmosphere contains readily combustible gases, vapors or dust particles. The heater employs an air mover which forces air through a metal heat sink with strategically placed electric heating elements. The terminal ends of the heating elements extend into a sealed and encapsulated explosion proof containment chamber which is connected to a centralized explosion proof enclosure. The explosion proof enclosure contains the control features and the electrical connections of the heater along with external accessories. The heating cycle is controlled via an electronic control circuit. The electronic circuit controls the process heating temperature, air mover operation, heating element operation, temperature measuring device operation, and monitors the total operation time of the heating elements while providing process failure feed back to the operator. | 12-27-2012 |

20140255263 | APPARATUS FOR THE LIQUID-PHASE SYNTHESIS OF ISOPRENE FROM ISOBUTYLENE AND FORMALDEHYDE - The apparatus for liquid-phase synthesis of isoprene from isobutylene and formaldehyde, comprising the following units of synthesis of isoprene precursors: 1,3-dioxanes synthesis unit; unit for TMC synthesis from isobutylene-containing fraction; unit for TMC synthesis from recycled concentrated isobutylene derived either from isoprene synthesis unit or from the unit for synthesis products separation and isoprene monomer isolation; isoprene synthesis unit; by-products decomposition unit; unit for synthesis products separation and isoprene monomer isolation. The apparatus is characterized with separation of by-product fractions from 1,3-dioxanes synthesis unit; with assignment of light fraction for sale or its supply for combined decomposition with the by-products (MDHP fraction), formed during separation of synthesis products and isolation of isoprene monomer; with assignment of heavy fraction for sale, at that TMC and 1,3-dioxanes that were formed in the corresponding units are simultaneously supplied for combined decomposition to isoprene synthesis unit while the unit for separation of synthesis products and isolation of isoprene monomer is directly connected with isoprene synthesis unit, by-products decomposition unit as well as with the unit for TMC synthesis from recycled concentrated isobutylene. The apparatus is also characterized by the following: 1,3-dioxanes synthesis unit includes by-products separation into light, medium and heavy fractions, from which the light fraction of by-products is fed for homogenous decomposition to isoprene synthesis unit and/or to by-products decomposition unit for combined decomposition with the by-products (MDHP fraction) formed during separation of synthesis products and isolation of isoprene monomer; the medium fraction of by-products is assigned for sale and/or mixed with the light fraction of by-products and supplied to by-products decomposition unit; and unreacted isobutylene from the unit of TMC synthesis from recycled concentrated isobutylene is supplied to the unit of TMC synthesis from isobutylene-containing fraction, being previously mixed. | 09-11-2014 |
