Abstract: A B S T R A C T     A field portable X-ray fluorescent spectrometer is described including a multichannel analyzer and a plurality of interchangeable sensor heads.  Each sensor head permits one of several radiation sources to irradiate a material to be analyzed.  The returned radiation is detected by a correspond-ing detector which provides corresponding data in response.          The multichannel analyzer uses the resulting detector data to calibrate the sensor head.  Each sensor head includes circuitry for identifying itself to the multichannel analyzer.  The analyzer automatically adapts its operation in accordance with this identification.  The multichannel analyzer utilizes the detector data to accumulate an energy spectrum of the material being analyzed.  A memory is provided for storing a number of reference spectra, any of one of which may be compared with the acquired spectrum for identification purposes.  The memory also stores previously acquired spectra for later analysis.      The analyzer also includes other operational features, such as normalization, window control, and ratio and concentration determination, to permit the operator to quantitatively analyze materials in the field.

Abstract: KERF GUIDE AND CAUTIONARY MARKER FOR A POWER DRIVEN TOOL     ABSTRACT OF THE DISCLOSURE      There is described a kerf guide and cautionary marker device for use with a power tool, particularly one employing a cutting type rotating tool, which guide and marker includes a groove cut into the table top of the apparatus.  The groove extends linearly from the front edge of the tool opening towards the front edge of the table top.  Disposed in the groove is a colored material, such as polystyrene, which has an exposed surface which can receive a scribe mark and/or cautionary instructions.  The contrasting color between the inserted material and the surrounding table top alerts the operator to the fact that he is approaching the rotating tool.          The operator aligns the guide mark on the work piece with the scribe mark on the material disposed in the groove and is thus able to properly position his work for the subsequent cutting operation.    If desired, a second groove, in line with the first groove, is disposed in the table top behind the tool and extends linearly from the rear edge of the tool piece opening to the rear edge of the table.  Colored material is disposed therein, and the exposed surface of the material can have cautionary instructions marked thereon.

Abstract: Abstract of the Disclosure Improved processes are provided for the production of a variety of azetidinones used in the partial synthesis of .beta.-lactam antibiotics.  These processes begin with chlorination of various types of anhydropenicillins to produce sulfur-free dichlorides which react with water or alcohols to produce acids or esters. These esters still contain a chlorine atom which undergoes ready intermolecular nucleophilic displacement by azide, cyanide, acetate or formate ions, or interamolecular displacement to form oxazolines, oxazolidones and oxa-anhydropenicillins.  Allylic bromination of these monocyclic and bicyclic azetidinones followed by reaction with azide ion produces an allylic azide group which can be reduced to an allylic amino group.  Most of the intermediates so produced are novel.  From these compounds there are produced new .beta.-lactam antibiotics such as l-oxa-benzylpenicillin.

Abstract: ABSTRACT        METHODS OF PRODUCING IMAGE INFORMATION FROM OBJECTS To produce image information from an object it is subjected to a continuous static magnetic field along a Z axis and to sets of sequences of gradient Gx, Gy and Gz to the magnetic field. Spins in a selected plane (the X-Z plane) are excited by selective rf pulses and an associated Gy gradient and the selected spins are subjected to a reversed Gy gradient together with a Gx gradient. The Gy gradient is then switched off and the direction of the Gx gradient is then repeatedly reversed.  During the action of reversal of the Gx gradient a small Gz gradient is provided. Each reversed Gx gradient is held constant for a sufficient time for a free induction decay signal to be generated thus providing a multiple echo of the spins in the selected plane.  Alternate signals are time-reversed and then both the time-reversed and non time-reversed signals are subject to Fourier transformation.

Abstract: RCA 75,438 ABSTRACT OF THE DISCLOSURE           An inverter applies a square-wave exciting voltage of horizontal deflection frequency to the primary winding of a ferroresonant power transformer.  A square-wave alternating polarity output voltage developed across a secondary winding of the ferroresonant transformer is half-wave rectified and applied to an input choke of a horizontal deflection circuit. The input choke is coupled to the series arrangement of a horizontal deflection winding and a trace capacitor.  A pincushion correction circuit switching transistor applies a DC voltage to the input choke at a controlled instant within the nonconduction interval of the half-wave rectified output voltage.  The peak-to-peak horizontal scanning current is a function of the average voltage developed across the trace capacitor.  This average voltage equals the average value of the voltage applied to the input choke.  By varying at a vertical rate in a parabolic manner the controlled instant at which the switching transistor applies the DC voltage to the input choke, the peak-to-peak horizontal scanning current is modulated at a vertical rate in a parabolic manner to provide side pincushion correction.
