Abstract: A waste digestion unit which comprises a container, a waste inlet into the container, an outlet from the container for digested waste, a gas bleed outlet from the container and a stirrer for stirring the contents of the container. The inlet, waste outlet, bleed outlet and stirrer are arranged so that the container can be mounted in position and partially filled with waste to a level defined by the waste outlet to provide a gas space above the waste. In this position of the container the bleed outlet is above the waste level and, the inlet discharges into the container below the waste level. The stirrer is capable of stirring the waste at said waste level and below said waste level.

Abstract: The invention relates to a portable workshop having various facilities for performing precision machine work at a work site and which includes a mobile trailer having first and second sections with transport wheel and suspension assemblies and a trailer hitch whereby the trailer may be easily towed from one work site to another. One section is separable from the other and the transport wheels remain with one platform while smaller wheels are provided on the other platform with elevating mechanism to lower the platform onto the smaller wheels. One platform may have equipment such as a welder which might be separated and used on one location at the job site while the other section has various tools, including a crane and a container for storing the tools, which might be moved to and utilized at another location at the site.

Abstract: This invention relates to a composition for melting ice, particularly for melting ice from driveways, sidewalks and the like.The composition includes a salt, more particularly sodium and/or potassium chloride and an amide such as urea.The method of making the composition includes the steps of (1) sizing the salt, (2) spraying a liquid amide thereon, and (3) drying the resultant composition.

Abstract: A barbeque grill with paper start facility comprising an open top receptacle defining a floor that includes one or more draft openings of adjustable size, a tinder receiver in association with the receptacle at its central axis and in alignment with the draft openings, a charcoal support grid and means for removably mounting same in the receptacle over the receptacle floor and above and adjacent the upper end of the tinder receiver, a charcoal receiver in the form of an open ended sleeve of impervious sheet metal material that includes a pair of oppositely located handles adjacent its upper end, which charcoal receiver is proportioned to be disposed in substantially congruent relation with the tinder receiver and on the charcoal support grid above the tinder receiver, and a food cooking grid and means for removably mounting same in the receptacle above the charcoal grid after the charcoal is ignited.

Abstract: A method and apparatus for achieving high quality treatment of organic waste water (both domestic and industrial types), which can also be used to treat organically contaminated water supplies or to reduce hazardous organic wastes (cyanides, PCBs, etc.)The apparatus operates at elevated pressures (up to about 35 psig), at high levels of dissolved oxygen (over 5 PPM), and at high concentrations of activated sludge (about 10,000 mg/l, MLSS). It consists of four separate process compartments (2 aeration compartments, a separator and a clarifier) which are contained within three vessels or alternatively in two vessels. The process compartments are linked in series by passageways and by piping and are maintained at a uniform pressure using a common manifold.The process is designed for simplicity of operation, compactness, and maintenance by a single part time attendant.

Abstract: A bag dispensing package includes a stack of flat bags and a surrounding flexible receptacle, conveniently in the form of a plastic bag. Each flat bag within the receptacle includes a pair of opposed walls, one of the walls having a manually graspable flap on an outwardly facing surface and the other wall including an extension that extends outwardly from the remainder of the bag. The flexible receptacle includes an access opening arranged to communicate with the manually graspable flap of the uppermost bag of the stack while the remainder of the receptacle retains the extension of the outermost bag within the receptacle. The access opening is normally closed, being defined by a pattern of perforations so that when it is desired to utilize the bags, the opening is formed by tearing the receptacle along the pattern of perforations. The uppermost bag is then removed by grasping the manually graspable flap and pulling the bag outwardly of the receptacle.
