Abstract: A heat press may include an upper assembly comprising a heat plate, a lower assembly comprising a platen, and a base assembly comprising a hinge mechanism. The upper assembly is pivotably coupled to the lower assembly via the hinge mechanism of the base assembly, according to various embodiments. The heat press may be generally configured to heat and compress, between the heat plate and the platen, a workpiece. A method for a heat press may also include a processor perform various operations, including activating a drive motor to drive an upper assembly of a heat press toward a lower assembly of the heat press to exert a compressive force on a workpiece disposed between a heat plate of the upper assembly and a platen of the lower assembly.

Abstract: The process of oxychlorination of ethylene to produce a product in which at least 15 molar per cent of the ethylene is transformed to 1,1,2-trichloroethane and 1,1,2,2-tetrachloroethane along with 1,2-dichloroethane and other more highly chlorinated saturated C.sub.2 compounds, the steps of passing a gaseous feed mixture of ethylene, hydrochloric acid and an oxygen-containing gas, with or without additional 1,2-dichloroethane, through a reaction zone at a temperature of 280.degree. to 370.degree. C, using a fluidized bed catalyst, and in which the molar feed ratios of the reactants are O.sub.2 /C.sub.2 H.sub.4 within the range of above 0.9 to 1.5, HCl/O.sub.2 within the range of 1.40 to 3.00, HCl/C.sub.2 H.sub.4 within the range of 2.20 to 3.65, and which, when 1,2-dichloroethane is present in the feed mixture, the latter is present in a molar proportion with respect to ethylene of less than 2.

Abstract: Oxychlorination of ethylene with hydrochloric acid and oxygen with a fixed bed catalyst subdivided into independent reaction zones whereby a substantial proportion of the ethylene is converted to 1,1,2-trichloroethane and 1,1,2,2-tetrachloroethane along with 1,2-dichloroethane.
