Abstract: ABSTRACT OF THE DISCLOSURE   a-Arylalkanoic acids or esters, ortho esters or amides thereof are prepared by forming an a-hydroxy ketal or thioketal of an aryl alkyl ketone, activating the a-hydroxy substituent with an esterifying agent to form the corresponding ketal or thioketal ester substrate, wherein the ester group is sufficiently labile to non-catalytically disassociate from the substrate in a protic or dipolar, aprotic solvent, maintaining the ester substrate in contact with the protic or dipolar, aprotic solvent or mixtures thereof for a time sufficient to form the corresponding a-arylalkanoic acid or ester, ortho ester or amide thereof, optionally concomitantly or sequentially hydrolyzing any ester, ortho ester or amide formed to the corresponding a-arylalkanoic acid and optionally converting the latter into a salt.  The rearrangement can be conducted in the absence of water and under acidic conditions to afford high yields of the desired a-arylalkanoic acids.

Granted: 1985-06-11
Abstract: ABSTRACT OF THE DISCLOSURE         For the detection of the presence of metal or mineral there is used a two electrode probe insertable into the geological formation.  The two electrodes are manufactured from different types of material.  When one electrode contacts a metal or mineral grain, the contact potential thereof is changed and there is a change of voltage between the electrodes.  The change of voltage is passed to indicator means.  After amplifying and possibly filtering the signals resulting from the change of voltage the indicator means indicates the change of potential in one or several audio visual components.  The magnitude of the change of potential indicates the type of metal or mineral that has been found.

Abstract: CONTROLLER FOR UNIFORM FLUID DISPENSING            ABSTRACT           A controller for uniformly dispensing fluid onto a substrate in response to movement between the    dispensing unit and the substrate has a sensor which senses the rate of relative movement and supplies a signal reflective of the movement to an operation device which in turn generates and supplies a control signal to a regulator.  The regulator is positioned in the fluid dispensing system and regulates the flow rate of the fluid to the dispensing unit so that the substrate receives a substan-tially uniform fluid coating per unit length.  The operation device receives the signal from the sensing means and computes the rate of relative movement.  The rate of relative movement is then compared to a preselected flow rate signal; and a signal is generated and supplied to the regulator reflective of the compari-son between the computed rate of movement and the preselected flow rate signal, so that the flow rate of the fluid varies substan-tially proportionally to the rate of relative movement between the dispensing unit and the substrate so that the amount of dispensed fluid per unit length of substrate is substantially constant.
