Abstract: ABSTRACT     The present invention provides an agent for the detection of esterolytic and/or proteolytic enzymes, consisting of an absorbent carrier, a film layer, a powder mixture, a lyophilisate, a solution or a reagent tablet containing an appropriate esterase and/or protease detection principle, a buffer and optionally further conventionally used additives, wherein the esterase and/or protease detection principle used is a combination of a specially substituted diazonium salt and an approp-riate ester, the reactivity of which is mutually coordinated by appropriate selection of the substituents in such a manner that a sufficiently rapid coupling takes place with the alcohol component liberated from the ester but no reaction with other components of the test solution occurs.     The present invention also provides new esters, which are substrates for esterolytic and/or proteolytic enzymes, said esters being compounds of the general formula:-  in which R"1, R"2, R"3 and R"4, which may be the same or different, are hydrogen atoms or lower alkyl, lower alkoxy, alkylamino or dialkylamino radicals or in which two adjacent substituents can also represent a fused benzene ring, A is a residue of an amino acid or of a peptide and B is a nitrogen protective group conventional in peptide chemistry or derived therefrom.     Furthermore, the present invention provides a process for the preparation of these new esters and, in addition, is concerned with the use thereof for pre-paring agents for the detection of esterolytic and/or proteolytic enzymes.

Abstract: ARC TUBE CONSTRUCTION ABSTRACT  OF THE DISCLOSURE    A vitreous arc tube is provided with constricted cylindrical neck portions intermediate the bulb portion proper and the pinched seals.  The constricted necks may be formed as an incident in the blowing of the bulb out of quartz tubing.  When the seal portions are pressed by the pinching jaws about the foliated inleads, the necks are maintained in substantially their original configuration and merely shrunk slightly about the in-leads extending through them.  An internal configuration is achieved which is substantially a surface of revolu-tion and fin-effect is avoided.

Abstract: ABSTRACT OF THE DISCLOSURE            A swimming pool wall, for placement in an excavation, is made up of a series of bendable plates having only vertical flanges for stiffening while permitting shaping the wall to a selected outline.  A resilient coping strip embranes the upper edge of the wall and houses a rigid metal bar to retain the upper edge of the wall in the desired configuration while other braces, at the lower edge of the wall extend from the plates to the outer edge portions of the flanges to securely maintain the lower edge of the wall in the desired configuration.  Vertical Z-shaped bars are secured to certain of the plates to further stiffen them and further braces, secured to the flanges, ex-tend diagonally upward into a concrete apron, selected ones of the diagonal braces carrying a form plate for defining the outer edge of the apron.  Rigid bars are used to hold corner plates to a desired curvature during assembly of the pool wall and its placement in the excavation.  After back-filling and forming the apron, those bars are removed.

Abstract: ABSTRACT OF THE DISCLOSURE         A channel-shaped sealing strip for vehicle door openings, for example, is shown.   It has a gripping section incorporating a metal carrier covered in flexible covering material which additionally defines longitudinally extending gripping lips.   The sealing strip is formed into a loop, ring or frame to suit a particular vehicle door opening.   Along those lengths of the loop intended to be fitted to the portions of the door opening between the latter's sharp bends or corners, the gripping section is provided with additional reinforcing members which seat in the base of the channel.   The reinforcing members are made of stiff metal but which can be bent slightly, when the sealing strip is fitted into position, so as to  hold the sealing strip in a slight curve, in any plane, to match the door shape.  At the positions in the loop where sharp bends or corners are required, the sealing strip is  com-pletely free of the reinforcing members.

Abstract: ABSTRACT     In general terms, a lightweight, flexible protective enclosure (1 or 32) is disclosed to protect a wearer from suffocation due to the presence of smoke or similar noxious fumes that are present in a contaminated environment.  In one case, the enclosure (1) has an opened bottom so that the wearer's head and upper body can be received therein.  Fastening means (14) are included by which to secure the enclosure (1) around the waist of the wearer and thereby prevent the contaminated environment from entering the enclosure.          In a second case, the enclosure (32) has an opened side (40) so that the wearer's head can be received therein.          Fastening means (48) are included by which to secure the opened side (40) against the chest of the wearer and thereby prevent the contaminated environment from entering the enclosure.  When worn in the contaminated environment, the enclosure (1 or 32) is adapted to provide an air space (25 or 50) of generally conical configuration in which a reserve supply of air is contained and from which the wearer may temporarily breathe to prevent suffocation.  Because of its flexible characteristic, the protective enclosure (1 or 32) may be folded into a compact package for convenient storage or distribution.

Abstract: Process For Stripping Uranium From An Alkyl Pyrophosphoric Acid Abstract A process is described for the recovery of tetravalent uranium from wet-process phosphoric acid utilizing an alkyl pyrophosphoric acid extractant or the like.  After extracting the tetravalent uranium from wet-process acid, iron is stripped from the pregnant extractant into an oxalic acid stripping solution and then the tetravalent uranium is stripped from the pregnant extractant into an oxalate stripping solution.  The oxalate stripping solution is an aqueous solution of an alkali metal or ammonium oxalate.  The barren extractant is recycled for contacting with fresh wet-process acid.  The uranium is oxidized and then precipitated in the oxalate stripping solution.  The precipitated solids are separated from the solution, and the uranium is dried to a UO3 product.

Abstract: ABSTRACT OF THE DISCLOSURE           This invention relates to a self-inverting, stable water-in-oil emulsion and to a process for preparing such an emulsion.  The emulsion comprises (1) a discontinuous aqueous phase containing a water-soluble polymer which discontinuous phase is dispersed into a continuous oil phase wherein the emulsion contains an inverting amount of an inverting surfactant and an emulsifying amount of a water-in-oil emulsifier. The invention is characterized in that the emulsion is prepared by polymerizing a water-in-oil emulsion of a water-soluble monomer containing a portion of the inverting surfactant and adding an additional amount of an inverting surfactant to the resultant water-in-oil emulsion of the water soluble polymer subsequent to polymerization.  The portion of the inverting surfac-tant added prior to the completion of polymerization is sufficient to increase the degree of inversion when the emulsion is inverted into a continuous aqueous phase but less than that which destabilizes the monomeric precursor or the emulsion of the polymer.

Abstract: ABSTRACT OF DISCLOSURE         The invention concerns an automatic, mass-obturated hand firearm comprising a body (1) with handle (2), a barrel (3) joined to the body, a sliding plug (4) with guide (5) constituted by the body and with cocking and firing mechanism (7), the guide of the sliding plug ascending rearward so that the rearward path of motion of the sliding plug deviates upward from the centre-line (8) of the barrel. The purpose is to eliminate the problem of automatic hand firearms that during shooting the barrel tends to rise upwards.         As taught by the invention, when the sliding plug (4) is in its forward position its centre of gravity (9) is located forward of the handle (2). The sliding plug (4) is preferably so disposed that it pushes to be in its major part forward of the rear end (10) of the barrel (3). Furthermore, the centre of gravity (9) of the sliding plug (4) is preferably located forward of the rear end (10) of the barrel (3). The guide (5) of the sliding plug (4) forms a preferably obliquely forward and downward inclined surface, against which the sliding plug rests so that when the rearward directed recoil force acts on the sliding plug this plug moves rearward and the surface of the sliding plug hits against the surface of the guide, producing on the body (1) a moment turning downward the muzzle of the barrel (3).
