Abstract: A system for measuring the electrical conductivity of disinfecting and rinsing solutions within a cleansing container includes a power supply for driving a pair of detectors and/or a meter, a conductivity probe for measuring the electrical conductance of the solutions, an oscillator, amplifier, and rectifier circuit, and indicators such as colored lights for indicating the type of solution within the container. The entire measuring system may be miniaturized and provided within the lid of the container. The system is particularly adapted to ensure that the correct steps are taken during the disinfection of contact lenses.

Abstract: Coal, petroleum residuum and similar carbonaceous feed materials are subjected to hydroconversion in the presence of molecular hydrogen to produce a hydroconversion effluent which is then subjected to one or more separation steps to remove lower molecular weight liquids and produce a heavy bottoms stream containing high molecular weight liquids and unconverted carbonaceous material. The viscosity of the bottoms streams produced in the separation step or steps is prevented from increasing rapidly by treating the feed to the separation step or steps with ammonia gas prior to or during the separation step or steps. The viscosity of the heavy bottoms stream produced in the final separation step is also controlled by treating these bottoms with ammonia gas. In a preferred embodiment of the invention, the effluent from the hydroconversion reactor is subjected to an atmospheric distillation followed by a vacuum distillation and the feeds to these distillations are contacted with ammonia during the distillations.
