Abstract: TITLE          A METHOD AND APPARATUS FOR THE INTRODUCTION                      OF A VAPOURIZED SAMPLE                 INTO AN ANALYTICAL TEST APPARATUS     INVENTORS               André H. Lawrence Lorne Elias ABSTRACT OF DISCLOSURE       This invention is concerned with an apparatus and a method for the introduction of vapourized samples into an apparatus for the analysis of such samples, such as a gas chromatograph, and especially a capillary gas chromatograph and ion mobility spectrometer.  A sample is vapourized or desorbed from a sample tube by heating the sample tube and then transferred by a carrier gas to the analytical apparatus by being withdrawn from the sample tube along and condensed on the inner surface of a heat conductive metal walled needle of a hypodermic syringe from which it is then vapourized and introduced into the analytical apparatus.          Suitable samples may also be introduced into an ion mobility spectrometer directly by placing a sample-charged sample tube into a sample-introduction port thereto.

Abstract: ABSTRACT OF THE DISCLOSURE         The arrangement contains a power shunt which is followed by a first amplifier circuit and can be used for processing the output current of an inductive current transformer having a wide dynamic range.  In order to provide high-precision  conversion with smaller currents, the power shunt is connected in series with a precision shunt which is connected in parallel with an overvoltage protection circuit which contains a switchable semiconductor rectifier and a control circuit which has the effect that the rectifier changes to a conductive state if the voltage at the precision shunt reaches a limit value.  The control circuit contains a symmetric voltage limiting element which is constructed as a pair of limiting diodes or as a fullwave rectifier, the output of which is con-nected to a reference diode.  In order to check the switching state of the overvoltage  protection cir-cuit, the series circuit consisting of the power shunt and the precision shunt is connected in parallel with a series circuit consisting of a first bridge resistor and a second bridge resistor which, together with the shunts, forms a balanced bridge circuit if the over-voltage protection circuit is inhibited, which bridge circuit is monitored by a window discriminator.

Abstract: CONCRETE BLOCK ADDITIVE AND IMPROVED CONCRETE BLOCKS PRODUCED THEREWITH              Inventor :  Lawrence F. Gelbman ABSTRACT OF THE DISCLOSURE     An additive used in the production of concrete blocks comprises a mixture of water and sodium bentonite.  Problem concrete blocks which previously were normally subject to im-proper molding or cracking during the molding, unmolding, handling and curing steps during the manufacture thereof, are now easily produced and properly molded without cracking resulting during any of these steps.  Whereas, it was previous-ly nearly impossible to manufacture any acceptable concrete blocks without employing sufficient quantities of fines in the concrete block mix, the additive allows formation of acceptable concrete blocks in the absence of any fines at all, thereby enabling much more reliable production of standard blocks, thin-walled blocks, and even more lightweight blocks than heretofore possible, because the gradation and characteristics and relative proportions of the coarse and fine constituents of the aggregate in the mix are rendered far less critical than heretofore.  The process of molding concrete blocks is rendered more efficient and quicker by the use of the additive and productivity is con-siderably increased, because the occurrence of "culls", cracked and defective blocks, is dramatically reduced or eliminated.          Also, the process for the formation of concrete blocks is improved by the use of additive in allowing easier and faster packing of the mix into the molds and easier stripping of the molded blocks from the block molds.
