Abstract:

A heater and limit switch assembly, particularly useful for installation in the conditioned air duct of a rooftop air conditioner. The loop of a rigid-loop heater, mounted on a vertical plate by two parallel legs, is modified to provide an inward offset portion leading to the second leg. Radiation, from the offset portion and its bend into the second leg, is received at close range by a simple disk-type limit switch, positioned on the plate outward of the second leg and facing the offset, inducing prompt response to any increase over design temperature.

US Classification:

562517

Abstract:

This invention involves a process for the carbonylation of a carbonylatable reactant, e. g. , an alkyl ester, a dialkyl ether or mixtures thereof by reacting the same with carbon monoxide. The process comprises effecting the carbonylation in the presence of a solution of a catalyst system containing a rhodium compound, an iodide and a lithium component at a temperature of from 50. degree. C. to 400. degree. C. at a carbon monoxide partial pressure of 1 psig to 15,000 psig. Hydrogen may also be present. The invention also concerns a carbonylation catalyst system effective for the addition of carbon monoxide to a carbonylatable reactant which comprises a solution containing as essential components a rhodium containing active component, an iodide and a lithium component.
