Abstract: ABSTRACT ADJUSTABLE AND FOLDABLE BED FRAME         An adjustable and foldable bed frame includes a pair of side rails and a pair of end rails extending transversely between the side rails.  Each end rail in-cludes a pair of elongated elements, with each of the elements having one end secured to a corresponding side rail and the other end of each element is in slidable relationship to the other element.  The elements are releasably locked together by means of a protrusion on one element which is receivable in an opening in the other element.  The opening defines a plurality of teeth, and the element with the protrusion has a spring loaded pawl member which is received in the opening and engages the teeth one at a time and permits the elements to be moved inwardly toward one another, while engagement between the pawl and the teeth prevents the elements from moving outwardly relative to one another.          Brackets are provided for pivotably mounting each of the elements to the respective side rails so that the elements can be rotated between a working position generally perpendicular to the respective side rails and a position generally parallel to and alongside the respec-tive side rails.  The bracket has one end secured to an element and an opposite end pivotably mounted to the side rail as with a rivet.

Abstract: Hydrocracking of Heavy Hydrocarbon Using Synthesis Gas Abstract Of The Disclosure A process is described for the hydrocracking of a heavy hydrocarbon, such as bitumen from tar sands.  A slurry of the bitumen, preferably together with coal, in the presence of a hydrogen-rich synthesis gas is passed through a confined hydrocracking zone, and the effluent emerging from the zone is separated into a gaseous stream containing a wide boiling range of material and a liquid stream containing heavy hydrocarbons.  This process provides increased liquid yields and increased H/C atomic ratios of liquid and solid, as well as significantly decreased hydrogen consumption.
