4448665 USE OF AMMONIA TO REDUCE THE VISCOSITY OF BOTTOMS STREAMS PRODUCED IN HYDROCONVERSION PROCESSES A package for radioactive material which comprises a radiation-absorbing vessel having a plug-type inner cover sealingly engaging this vessel and an outer security cover overlying the massive plug-type cover and defining a clearance therewith in which gas can be monitored to detect failure of the seal, this safety cover being sealed to the vessel so that the latter chamber is sealed from the atmosphere. According to the invention, this chamber is sealed with gas at a superatmospheric pressure which is also above the pressure within the vessel and the pressure of the chamber is monitored, a drop in pressure signaling a breach either of the seal between the plug-type cover and the interior of the vessel or between the safety cover and the vessel.

4448661 DEVICE FOR MEASURING THE BATH TEMPERATURE IN A FUSED SALT ELECTROLYTIC CELL USED FOR THE PRODUCTION OF ALUMINUM Rolf Roggen, Sion, Switzerland assigned to Swiss Aluminium Ltd

Sioma Zaczepinski, Rustom M Billimoria, Fran Tao, Christopher G Lington, Karl W Plumlee assigned to Exxon Research and Engineering Co 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.

An apparatus for final clearing of waste water in a settling tank includes an inverted conical collecting basin having openings in the walls thereof. An annular air chamber encircles and is attached to the upper edge of the basin and floats in the waste water. Waste water enters the collecting basin through the openings therein and sludge in the water settles to the bottom of the basin. The cleared water at the top of the basin flows into an overflow receptacle and is removed therefrom by a pipeline. The sludge at the bottom of the basin is conveyed upwardly by a conveying device through a conveying pipe to a collecting receptacle and is removed therefrom by a pipeline.

4448690 SUBSURFACE WASTE DISPOSAL SYSTEM Sam W Maphis assigned to Genstar Waste Transfer Inc IM~ttmAt

A system for utilizing and disposing of sludge and other wastes employs an artificially created perched bed and a subsurface injector system that applies such wastes in a liquid or semi-liquid state to an aerobic portion of the bed. The solids from the waste mixture are suspended in the bed while the liquids percolate through the bed to an underdrain system for collection, monitoring, further treatment, ultimate reuse, or direct discharge. The system provides closed loop disposal of the waste stream in a completely controlled environment without impact to the local environmental system. The bed's selected media can be changed into a beneficial by-product-top soil-through the addition of the waste material. Subsurface injection may be accomplished by moving an injector sweep either by a vehicle supported on the artificial bed or by a movable superstructure. Repeated applications of sludge or waste may be made to the bed without plugging due to the disruptive action of the injector sweep on the bed material.

This invention relates to inspection or X-ray testing system for vehicle wheels consisting of a rim and a supporting structure of the kind comprising an X-ray tube, and X-ray screen with a post-positioned monitor and a system for reception of the wheel fed in rim-down, for placing the same into the beam path of the X-ray tube, and for ejecting the wheel after inspection. To shorten the inspection or testing period, the system according to the invention comprises a chute displaceable around a horizontal pivot spindle for the wheel which may be pivoted to the appropriate positions for reception, immobilization during the testing or inspection and the ejection of the wheel. The pivot spindle extends parallel to the X-ray screen as well as to the chute. The chute has a stop system to establish the testing position of the wheel on the chute and a clamping mechanism for immobilizing the wheel slid into the testing position. The X-ray tube is movable at least between a first operating position for the transillumination of the axial rim halves, and a second operating position for the transillumination of the wheel element support structure.
