Abstract: ABSTRACT OF THE DISCLOSURE     Apparatus and method for photometrically analyzing a constituent of interest in body or other fluids and well suited for kinetic determinations which are temperature-and-time dependent.  There is provided a sample holder holding a cuvette supporting a liquid sample and other reactants among which is a trigger reactant to initiate the reaction which is analyzed.  The trigger and the other reactants are initially isolated in the cuvette.  The holder, one of a series, is moved periodically to move the cuvette, one of a series handled sequentially, to a temperature-sensing and preheating station, to a station where the contents of the-cuvette are mixed to enable the reaction to proceed, to an optical station where the reaction is viewed for an optical density determination over a period of time under temperature conditions regulated within limits, and to a station for sensing the temperature of the mixture, by immersion of a temperature sensor therein, and supplying data for estimation of the real temperature during the optical determination for inclusion in the determination of the concentration of the constituent of interest, all in a relatively short period of time.

Abstract: ABSTRACT           An electrophotographic medium which comprises a transparent substrate, ohmic layer and coating of photoconductive material, all of which form a modulating structure for the radiant energy that is adapted to be projected through the substrate; a dielectric layer (storage medium) intimately bonded to the surface of the photoconductive coating;and a conductive electrode in intimate contact with the dielectric layer.  The structure is used by connecting a d.c. voltage across the outer electrode and the ohmic layer and projecting the image onto the electrophotographic medium from the bottom surface of the substrate.  The charge image appears on the dielectric layer.  The charge image is read out with an electronic beam or toned and fixed or transferred.  During use the electrode is brought into intimate contact with the dielectric layer and removed after forming the charge image in order to enable the medium to be processed further without the electrode.  The interface between the dielectric layer and electrode preferably is liquid, at least when originally formed, and may comprise a conductive fluid or an organic or inorganic material or a low melting point metal that is easily stripped off the dielectric surface.  Imaging apparatus incorporating,and a method of using,said medium also is described.

Abstract: Abstract of the Disclosure A casting powder applicator includes a bin for powder and a laterally extending duct having a discharge opening in front, preferably of adjustable cross-section and disposed above a mold cavity; a partition serves as bottom for the bin and for the duct as far as the powder is concerned, but the partition is permeable for gas, possibly at a variable degree of permeability; a plenum chamber under the partition is fed with gas which is forced through the partition to move the powder from the bin into the duct and towards the discharge opening thereof from which the powder falls or flows into the mold cavity underneath at a rate controlled by the slag temperature.  The application of gas pressure is controllable and insufficient to cause the powder to be blown out of the discharge opening in a cloud so that flying dust does not develop.

Abstract: ABSTRACT Disclosed is a switching power amplifier of high efficiency, small size and weight and excellent dynamic performance, together with reduced pulsating for both input and output currents.  Switching ripple is completely eliminated, unlike in conventional designs. The amplifier is provided by a pair of converters with feedback control of the pulse width of applied switching pulses.  Each converter has two inductances, one in series with a DC power source and one in series with the load, storage capacitance, and switching means for alternately connecting the junction between the first inductance and the storage capacitance to ground return for the source, and connecting the junction between the storage capacitance and the second inductance to ground return for the load.  When the input inductances of the two converters are made equal, the ripple input currents to the two converters result in zero-ripple source current.  The switching means for one of the two converters is driven with the complement of the pulse-width modulated control signal applied to the other.  In each converter, the input and output inductors are coupled by providing the inductors as windings of a transformer designed for the condition n = k, where n is equal to the square root of the ratio of the self-inductances of the input and output windings, and k is the coupling coefficient between the windings for zero output current ripple.
