Abstract: Abstract of the Disclosure A novel process for the preparation of 2-(2',2',2'-trihalogeno-ethyl)-4-halogenocyclobutan-l-ones of the formula   in which one of the radicals R1 and R2 is methyl and the other is hydrogen or methyl, or R1 and R2 together are an alkylene group having 2 to 4 carbon atoms, and X and Y are each chlorine or bromine, but if X is bromine Y must always be bromine, is disclosed. The process comprises reacting a 2,4,4,4-tetrahalogeno-butyric acid chloride in the presence of an organic base with an ethylene compound which is disubstituted in 1-position by the radicals R1 and R2, as defined above, to form a 2-(2',2',2'-trihalogenoethyl)-2-halogenocyclobutan-1-one and then re-arranging the latter,in the presence of a catalyst, into a 2-(2',2',2'-trihalogenoethyl)-4-halogenocyclobutann-1-one of formula I. The 2-(2',2',-2'-trihalogenoethyl)-4-halogenocyclo-butan-1-ones of formula 1 are valuable intermediates for the preparation of 2-(2',2'-dihalogenovinyl)-cyclopropanecarboxylic acid and its insecticidally active esters. The 2-(2',2',2'-trihalogenoethyl)-4-halogenocyclobutan-1-ones of the above formula and the intermediates used for their preparation are novel compounds.

Abstract: CHEMICAL CUTTING APPARATUS AND METHOD FOR USE IN WELLS            Abstract A chemical cutting apparatus and method for cutting objects in well bores such as, fox example, tubing in the bore of an oil or gas well.  The apparatus is properly positioned relative to the object to he cut by means of a casing collar locator and an igniter is fired, which in turn activates a gas generator.  Pressure from the gas generator axially displaces a slidable piston having one ox more wedges pivotally connected thereto.  Movement of the piston both pivots and extends the wedge, thereby bringing the wedge into contact with the object to be cut and anchoring the apparatus relative to the object to be cut.  The pressure generated in the gas generator is com-municated through a passageway in the slidable piston and forces a chemical cutting agent into a chamber containing a reactant.          The reaction of the chemical cutting agent and reactant increases the pressure and temperature within the chamber thereby displac-ing along the axis a second slidable piston.  Movement of the second slidable piston exposes radial exhaust orifices thereby allowing the reacting elements in the chamber to escape with great velocity and to contact the object to be cut.

Abstract: PRESSURE-SENSITIVE TRANSFER ELEMENTS AND PROCESS            Abstract of the Disclosure A thin, pressure-sensitive, ink-releasing transfer ele-ment, such as a ribbon, capable of releasing a substantially uniform and intense amount of smudge-resistant ink at least about four times from overlapping impressed areas of the ink layer corresponding to each double image width during high speed printing use on "hammer-impression" high speed type-writers.  The thinness of the ribbon is important not only to accommodate a maximum amount of ribbon on the feed spool, but primarily in order to provide a ribbon which is operative in such typewriters to produce images having excellent sharpness, uniform intensity, edge profile and freedom from pick-over, which properties also result from the cooperative nature of the ink and undercoating used on such ribbons.  The present method involves applying an ink layer comprising a microporous resinous binder containing pressure-exudable, substantially-solid, thixotropic ink having a viscosity of at least about 100,000 centipoises and containing a hydrophilic pigment and a wetting agent having both hydrophilic and oleophilic radicals, by means of a volatile coating vehicle comprising a miscible. mixture of (a) a volatile liquid solvent which is a solvent for the resinous binder and for the ink vehicle but is a non-solvent for the wetting agent and (b) another less volatile liquid which is a solvent for the wetting agent and for the ink vehicle but is a non-solvent for the resinous binder.

Abstract: ABSTRACT OF THE DISCLOSURE           Agitation of the surface of a body of water by a falling stream of water results in the entrainment of air bubbles which are carried underneath the surface.  These air bubbles are collected in a tank having a submerged open bottom. Air pressure is produced within the tank and utilized to perform useful work by operating a pneumatic pressure transformer which in turn produces high pressure air for operating a series of air-lift pumps.  In an alternative embodiment a reciprocating piston motor or turbine is positioned in a path of flow between a portion of the body of water containing relatively few air bubbles and another portion containing a relatively large quantity of bubbles.  Flow through this path takes place by reason of a difference in densities and is available to do useful work.

Abstract: ABSTRACT OF THE DISCLOSURE A pyrohydrolysis system is provided for the recovery of valuable components from waste and spent materials generated in electrolytic aluminum reduction facilities. The pyrohydrolysis system employs a dense phase fluidized bed reaction zone for the pyrohydrolysis of coarse feed, a dilute phase fluidized reaction zone for pyrohydrolyzing fine feed, this zone being superimposed and interconnected with the dense phase zone. The offgases, after removal of the solids, are contacted in a dilute phase fluidized zone, with a source of Al2O3 to remove residual Na values and to produce Na-free HF. The solids from the first dilute zone, having a desired high Na:Al atom ratio, can be combined with the product clinker from the dense bed zone. The offgas, containing the source of Al2O3, is subjected to solids separation, the solids-free and Na-free HF is utilized, while the solids of low Na:Al mole ratio are recycled to the residual Na conversion step.
