Abstract: ABSTRACT OF THE DISCLQSURE      A back-to-back proportioning valve assembly for a cross-split braking system is disclosed.  The proportioning valve assembly comprises an assembly housing defining a substantially cylindri-cal bore extending therethrough.  The bore defines first and second rear brake outlet openings.  In the assembly housing are disposed a pair of inlet passages extending within the cylindrical bore connected with respective first and second master cylinder chambers,  A pair of front brake outlet openings are also dis-posed in the assembly housing.  First and second proportioning valves are positioned in back-to-back relationship within the cylindrical bore adjacent respective first and second rear brake outlet openings for proportioning the inlet pressure to the rear brake outlets.  A pair of bypass channels, for bypassing each of the proportioning valves, are provided to be opened upon failure of one of the braking systems.  A differential pressure piston, in the form of a cylindrical spool, is disposed within the cylin-drical bore to overlie the bypass channel ports.  Upon failure of one of the braking systems, the differential piston shifts, thus opening one of the bypass ports and providing a direct fluid communication path from the inlet passage to the rear brake out-let opening, thus bypassing the proportioning valve.

Abstract: IMPROVED PROCESS FOR PRODUCING A MIXTURE OF BRANCHED AND LINEAR CARBOXYLIC ACID SALTS ABSTRACT         An improved process for reacting a mixture of branched and linear alcohols with a caustic, optionally in the presence of a catalyst, to produce a reaction mixture containing carboxylic acid salts, and to liberate hydrogen.  The improvement comprises introducing into the reaction mixture at about a time when a significant evolution of hydrogen from the mixture begins to occur, an effective amount of an inert diluent for the reaction mixture.  The effective amount is sufficient to maintain the fluidity of the reaction mixture.  A preferred diluent is mineral oil. The improvement reduces the tendency of the reaction mixture to foam and solidify, thus permitting the reaction to proceed to completion and permitting the easy removal of the reaction mixture from the reaction zone.  Additionally, the improvement insures that the branched and linear mixture of carboxylic acid salts produced substantially corresponds to the branched and linear mixture of alcohols reacted.

Abstract: ABSTRACT OF THE DISCLOSURE   A process and apparatus is provided for the production of calcium silicate-containing stone blanks which are useful in constructing building walls. A crude mixture, of a granulated silicate-containing material, lime, water, a cement and a foaming agent, is subjected to no more than a minimum application of external pressure and is subsequently hardened in an autoclave.  The cement produces the necessary strength for the blank, so that the latter becomes trans-portable while the final strength is achieved by reaction of the silicate-con-taining material during the autoclave treatment.  In order to arrive at accept-able molding times and in order to achieve a simplified process with slight fragment bulk density and optimal heat damping characteristics, the crude mix-ture is rendered pourable, is filled into molds in a quantity corresponding to the fragment volume of the stone blank, and the crude mixture in the mold is heated essentially uniformly to a temperature between 45°C and 90°C until achiev-ing the desired blank-strength.  The production of the blanks is carried out in molds, which are equipped with a heating system for heating the crude mixture in the molds, whereby the heating takes place by means of an electric high fre-quency field and/or indirectly via the molds and possibly via mold spikes, which are individually heatable and serve for the development of a pattern of holes in the stone.

Abstract: Abstract of the Disclosure A very fast acting valve capable of producing a very well-defined plug of gas suitable for filling a theta pinch vacuum vessel is given.  The valve requires no springs, instead being stopped mainly by a nonlinear force.  Thus, the valve is not subject to bouncing; and the ratio of the size of the valve housing to the size of the valve stem is smaller than it would be if springs were needed to stop the valve stem.    Furthermore, the valve can be used for thousands of valve firings with no apparent valve damage.

Abstract: ABSTRACT OF THE DISCLOSURE:    An improved method for decontaminating the coolant system of water-cooled nuclear power reactors and for re-generating the decontamination solution.  A small amount of one or more weak-acid organic complexing-agents is added to the reactor coolant, and the pH is adjusted to form a decon-tamination solution which is circulated throughout the coolant system to dissolve metal oxides from the interior surfaces and complex the resulting metal ions and radio-nuclide ions.  The coolant containing the complexed metal ions and radionuclide ions is passed through a strong-base anion exchange resin bed which has been presaturated with a solution containing the complexing agents in the same ratio and having the same pH as the decontamination solution.  As the decontamination solution passes through the resin bed, metal-complexed anions are exchanged for the metal-ion-free anions on the bed, while metal-ion-free anions in the solution pass through the bed, thus removing the metal ions and regenerating the decontamination solution.

Abstract: ABSTRACT OF THE DISCLOSURE         The detection of surface defects in mechanical parts is effected by the analysis of diffracted light coming from these defects.  The detection method includes the steps of illuminating the surface of the part to be examined with incoherent light and forming a flat image of the said surface in a transparent photosensitive layer of a spatial light modulator.  The spatial distribution of the intensity of the incoherent light reflected by the said surface produces a corresponding and proportional spatial distri-bution of values of refractive index in the photosensitive layer.  This layer is illuminated with plane polarized, coherent light by frame scanning in elementary areas. during the scanning operation, the variations in at least one of the polarization components of the coherent light are detected by a matrix of converters after the light has traversed the said transparent photosensitive medium.
