Abstract: ABSTRACT OF THE DISCLOSURE           An explosion-proof electrical enclosure has a body with two threaded caps closing access openings on opposite ends of the body. Within the body is an electrical switch operable by a handle positioned outside the body. The caps are held against rotation by bolts which extend through the body and are resiliently urged into recesses in the caps. These bolts are accessible from outside the body so that they can be moved out of the recesses thereby allowing the caps to be rotated and unthreaded. A safety interlock mechanism includes a spacer positioned, when the handle is in the switch-closed position, between the inner ends of the bolts to prevent unlocking move-ment of the bolts and interconnected to the handle so as to be moved out of that blocking position when the handle is in the switch-open position. A threaded pin extends through the body and engages the mounting for the spacer so that by rotating the pin it moves axially thereof in the body. As it does so it engages the mounting for the spacer to move the spacer sidewise out of its blocking position between the inner ends of the bolts.

Abstract: ABSTRACT OF THE DISCLOSURE         Disclosed is a process for rejuvenating and reclaiming useful hydrocarbon oils from contaminated waste oils.  The process comprises dehydrating the waste oil and thereafter dissolving the dehydrated oil in a selected amount of isopropanol or N-propanol at a temperature of from 45°C. to 80°C.  The undissolved waste matter is separated and the residual oil/solvent fraction is distilled to re-cover the decontaminated oil and the solvent.    The recovered oil can be further clarified by treatment with a bleaching clay or activated carbon at elevated temperatures.  The process is more efficient and economic than those known heretofore resulting in high yields of reclaimed oil and more environ-mentally acceptable waste products.

Abstract: ABSTRACT OF THE DISCLOSURE         An improvement in the separation of a multi-component mixture, especially a well head stream, into gaseous and liquid phases by multi-component flash separation at reducing pressures, comprises recycling at least a part of the gaseous fraction recovered from a stage after the first stage to a preceding stage, and preferably the immediately preceding stage, to mix with the liquid phase which is separated in said preceding stage and at substantially the pressure of said preceding stage   This (a) increases the gas/liquid ratio in each stage, the amount of liquid receovered from the last stage and the proportion of medium-boiling components therein;  (b) results in more gas being available from the higher pressure stages and (c)  yields gases having narrower boiling ranges.  Three separation stages are preferred and pipeline gas, crude LPG and a local fuel gas to supply the energy requirements of the separation can be derived from the gaseous fractions recovered from the separation stages.
