Abstract: ABSTRACT OF THE DISCLOSURE          Apparatus and method for sharpening a studded crown of a rock drill, with a rotating grinding wheel and an apparatus for rotating the wheel, such as an electromotor.  A periphery of the rotating grinding wheel constitutes the sharpening surface for grinding the hard-metal stud on the studded crown, with the grinding wheel being supported to rotate about its own axis and swivel with respect to the stud to be sharpened, such that the circular or swiveling motion of the rotating grinding wheel takes place about a swiveling axis passing through the stud to be sharpened.  The shape of the sharpening periphery of the grinding wheel may be advantageously fluted or curved such that the periphery itself forms a substantially circular arc, whereby the combined rotational and swiveling motion of the grinding wheel produces a substantially hemispherical shape on the hard-metal stud being sharpened.

Abstract: ABSTRACT          The invention relates to an apparatus for neutralizing acidified water by means of limestone or a similar basic material.  It provides an apparatus which can be used for increasing the pH-value of water coming from wells or the like and feeding just one or a few households.            According to the invention there is in the water supply system interconnected an apparatus having a fluidization chamber for solid basic particles the size of which is within the approximate range 1-10 mms.  The water enters the chamber at the lower part thereof and flows upwards.  The cross-section area of the chamber increases in the flow direction so that the heaviest particles will float near the bottom and Lighter particles at higher levels.  A funnel-shaped storage chamber is located above the fluidization chamber and does successively replace consumed material.

Abstract: Abstract A process wherein coal is reacted with a hot gas stream to produce acetylene.  The process comprises the sequential steps of reacting a fuel, oxygen and steam under controlled conditions of temperature to produce a hot gas stream principally comprising hydrogen, carbon monoxide and steam along with minor amounts of carbon dioxide, and essentially free of O, OH and O2.   The hot gas stream is accelerated to a high velocity and impinged upon a stream of particulate bituminous or subbituminous coal and thereafter the mixture of hot gas and coal is decelerated to a velocity of from about 150 to 300 feet per second.  The amounts of the streams of particulate coal and hot gas are controlled to produce in the reaction zone a pressure in the range of from about 10 to 100 psia and a temperature of from about 1800° to 3000°F.  The mixture of coal and hot gas is maintained at that pressure and temperature for a time of from about 2 to 30 milliseconds to produce a product stream including char and acetylene.  The temperature of the product stream is then reduced to less than about 900°F in a time of less than about 2 milliseconds to substantially arrest any further reactions and the acetylene is recovered therefrom.  The char is recovered and used as at least a part of the fuel used to produce hot gas.

Abstract: WAFER LEVEL INTEGRATION TECHNIQUE                 ABSTRACT OF THE DISCLOSURE Wafer level integration is provided by using individually integrated circuits on a wafer substrate and generating an electrically ordered matrix of func-tional integrated circuits assigned from a random dis-tribution of functional, partially functional, and non-functional circuits.  Each circuit is individually tested for functionality and thereafter a conductive grid is formed on said wafer to interconnect all of the circuits on the wafer.  Circuits that are tested as being non-functional are isolated prior to formation of the interconnecting grid by eliminating fuses that pro-vide connections between the defective circuit and the conductive grid.  Each matrix row includes redundant decoder lines.  The redundant decoder lines are pro-grammed to reassign functional circuits from a semicon-ductor wafer substrate location to a matrix row location in another matrix row having defective circuits.  In this way, complete functional matrix rows are formed. Associated input and output lines are assigned in a similar manner to a correct bit position within an input and output byte.

Abstract: ABSTRACT OF THE DISCLOSURE Transportation apparatus, such as escalators and moving walks,  having controlled stopping characteristics. Deceleration is directly regulated via a deceleration servo loop which provides a current reference signal for an inner current  loop.  Brake current limiting prior to the  con-trolled stop, as well as mechanically limiting the maximum brake gap, results in faster transient response, and a more linear braking torque versus brake current characteristics. Multiple drive units operate from  a  common deceleration reference signal, while having independent servo loops each operating from a "local" deceleration signal.
