Abstract: Abstract of the Disclosure For the combustion of finely-ground coal which is slow to ignite, the coal is preheated before it enters the combustion chamber.  The preheating can be carried out by passing cold air around the outside of the combustion chamber and then using this heated air to preheat the coal in bunkers.  For this purpose the combustion chamber is provided with a hollow casing surround-ing the combustion chamber proper and a partition in the hollow casing pro-vides an annular outer space and a concentric annular inner space.  A helical baffle arrangement is also provided in the inner and outer spaces to guide the cold air down the outer space and up the inner space.  The coal is burned below the melting point of the coal slag and this produces a soft ash rather than molten material.  The ash is cleaner and cannot bake onto burner housing.  Heat is stored in the combustion chamber wall and the time of residence of the coal in the combustion chamber is increased by impart-ing a spiral motion to the coal and/or air supplied to the combustion chamber.     The layer residence ensures more complete combustion.

Abstract: PHYSIOLOGICALLY ADAPTIVE CARDIAC PACEMAKER                 ABSTRACT OF THE INVENTION         A cardiac pacemaker is disclosed having means for automatically adjusting the rate of operation to correspond to physiological changes.  Circuitry is provided for detecting the presence or absence of an evoked T wave following a de-livered stimulus pulse, and for measuring the time interval between the stimulus pulse and the following T wave.  The escape interval of the pacemaker pulse generator is varied in accordance with the detected stimulus - T interval and in the same direction, so as to vary the pacing rate in accordance with variations in such interval.  Since this interval in turn corresponds to physiological changes, the pacemaker is adapted to automatically follow the patient's physiological changes.  When an evoked T wave is absent fol-lowing a delivered stimulus pulse the pacer stimulus generator is adjusted for delivery of a pacing signal of greater energy.          Circuitry is also provided for lowering the pacing energy level in response to external signals, whereby threshold testing may be achieved.

Abstract: ABSTRACT OF THE DISCLOSURE The invention provides a novel and efficient method for the elimination of protecting groups, e.g. benzyloxycarbonyl group, from a protected amino acid, peptide or derivative thereof having at least one functional group protected by a protecting group, e.g. a lower alkyl ester of N-benzyloxycarbonyl-.alpha.-L-aspartyl-L-phenylalanine by catalytic hydrogen reduction to produce free amino acid, peptide or derivative thereof.  In contrast to the conventional procedures in which the reaction is carried out in a solvent dissolving both the starting compound and the product compound or a solvent dissolving the starting compound but not dissolving the product compound, the inventive method utilizes a binary two-phase reaction medium composed of water and an organic solvent not freely miscible with water such as toluene .  The reaction takes place in the organic phase con-taining the starting compound dissolved and the catalyst dispersed therein whereas the reaction product which is water-soluble is smoothly  and successively transferred into the aqueous phase so that advantages are obtained in the unexpectedly high yield of the product as well as in the easiness of handling the reaction mixture after completion of the reaction.

Abstract: ABSTRACT Screw threaded components are manufactured from sheet metal solely through a stamping operation.  In this method one side of a workpiece is engaged by a die member having ridges thereon so as to provide a plurality of substant-ially parallel grooves extending in said one side from adjacent a first edge to adjacent the second edge opposite the first edge, the grooves being made more shallow and narrower than the desired screw thread.  The one side is then engaged by an additional member which has ridges effective to deepen and widen the grooves to achieve the desired contour of the screw thread, the ridges being spaced apart a distance equal to the pitch of the thread to be produced.  The workpiece is then bent to impart a substantially cylindrical configuration thereto with the ends of adjacent ones of the grooves being positioned substantially in alignment with each other at the first and second edges to define a helix.  This results in a drastic reduction in the cost of producing such screw threaded parts and much faster pro-duction and savings of material while providing parts of superior performance and better appearance.
