Abstract: This procedure means that molybdenum core wire in tungsten filament coils for light sources can be dissolved chemically without releasing nitrous gases to the atmosphere. Since the solution reaction takes place under vacuum and with a metered supply of oxygen, while retaining the vacuum, the nitrous gases which have been formed can be converted in the process. The process acid also contains sulphuric acid and water. The reaction vessel can be cooled by means of tempering in the introductory stage of the dissolution reaction, since this stage is markedly exothermic. The reaction vessel can be heated in the final stage so that the dissolution of core wire becomes complete. 
<??>The device for implementing the procedure consists of a reaction vessel (1) with a tempering jacket (2) and fitted with an inlet and outlet (6) for process acid. An oxygen pipe (7) containing a metering valve (8) runs to the vessel (1). This valve is controlled by pressure-sensing devices (12, 13) on a liquid trap (10) fitted on a pipeline (9) running from the reaction vessel. The liquid trap can suitably contain an alkali solution. The pipeline (9) can be fitted with a cooler (11) for condensate acid vapour from the reaction vessel (1).

Abstract: A product counter apparatus is disclosed comprising a support element which bears against the products, typically printed products, which are to be counted. A holder device is mounted at the support element. Secured to such holder device is a substantially L-shaped spring or resilient element containing two leg members. The one leg member of such resilient or spring element extends substantially transversely with respect to a predetermined conveying direction of the printed products and protrudes by means of its free end past the holder device. The other leg member of the resilient or spring element is clamped at its end, and thus, can be elastically deflected transversely to a plane containing the printed products. Retained in the holder device is an inductive proximity switch. The printed products moving past the counter apparatus impact at their leading edge at the end of the one leg member which serves as a feeler or sensor and deflect the latter in their product conveying direction. At the same time the feeler is raised while there is deflected the other leg member of the resilient or spring element. Consequently, it is possible for the feeler to be released from the printed product engaging thereat and to resiliently return back into its starting position. During approach of the feeler at the proximity switch the latter generates a counting signal which is inputted to a counter mechanism.

Abstract: Pulverising apparatus comprising a generally cylindrical vessel (11), feed means (16) for feeding the material to be pulverized into said vessel, a plurality of circumferentially spaced fluid injection nozzles (24) each angled between a radius of the cylindrical vessel passing through the nozzles and a direction perpendicular to said radius, to inject fluid into the vessel and induce an axially flowing vortex (25) in the vessel having its axis generally centrally of the vessel, transverse wall means (12) at a location remote from the nozzles to intercept the vortex and to deflect a portion (26) of the fluid medium and entrained particles of material to effect a recirculation of the fluid medium within the vessel and thus to form a curtain surrounding the vortex. The material is pulverized by interparticle collisions and the curtain reduces high speed particle contact with the cylindrical wall of the vessel. An outlet (14) in said transverse wall allows a fraction of the pulverized material below a predetermined mass to pass generally along the axis of the vortex. The means (16) for feeding the material to be pulverized are arranged to feed the material to a point adjacent the axial centre of the vessel in the vicinity of said nozzles.

Abstract: A seal ring has a lip ring which is at least radially resilient and has a sealing lip for sealing about a reprocating or rotating machine part and a support surface axially spaced from the sealing lip. A reinforcing ring is radially spaced from the lip ring and coaxial therewith. An intermediate ring extends, in part, approximately parallel to the axis of the lip and reinforcing rings. It joins the lip ring at one end within the axial range of the support surface and, via the axis parallel part, joins the reinforcing ring at its other end within an axial region bounded by the sealing lip and the end of the support surface axially remote therefrom. This arrangement of the intermediate ring accommodates radial displacement of the machine part without displacing of the sealing lip from the machine part by tilting moments.

Abstract: A method for manufacturing plastically bonded propulsive powders and explosives by means of an extruder which comprises a housing with at least one entry opening, under certain conditions a solvent supplementing opening, two co- or counterrotating screw shafts and a forming head. The method makes possible continuous production with minimal binder components of 4-6 percent. Firstly, the plastic binder in a fixed, soluble or suspended form is added by means of an entry opening for a period of time until the screws float in the plastic binder without opposing friction and without friction with the walls. The components of the propulsive powder, or correspondingly the explosive material in crystalline form, are added in steadily increasing proportions with a simultaneous reduction of the portion of the plastic binder and finally, the mixture ratio is held constant.

Abstract: A process for casting molten metallic material having a solidification range of temperatures, especially alloys containing more than 80% aluminium, involves simultaneously stirring and cooling the molten material to a temperature between 0 DEG  C. and 75 DEG  C. above the liquidus temperature of the metallic material using hollow heat transfer rods (9) extending across a duct (4), down which the material is caused to flow. The material is then caused to solidify with a substantially non-dendritic microstructure by rapidly cooling it in a continuous casting machine. The solidified bar so produced may then be reheated at a steady rate to a point between its liquidus and solidus temperature until it contains between 30% and 70% by volume solids content but can still be maneuvered without losing its shape. It may then, with a minimum of delay, be rapidly formed into a solid article of any desired shape by, for example, casting in a pressure casting machine.

Abstract: An improved process for preparing (4S)-6-fluoro-spiro-[chroman-4,4 min -imidazolidine]-2 min ,5 min -dione (sorbinil) or its (2R)-methyl derivative (2-methylsorbinil) is disclosed herein, starting from p-fluorophenol in each instance. The final products obtained have known pharmaceutical value as agents for the control of certain chronic diabetic complications. Key steps concerned with the process involve converting p-fluorophenol into the appropriate  beta -(4-fluorophenoxy)-alkane halide, followed by amidoalkylation with N-benzoyl or N-(lower alkanoyl)- alpha -hydroxyglycine to form an intermediate 2-amidoalkylated derivative thereof, and then dehydration and spiroalkylation of said intermediate by treatment with a dehydrating agent and a base to yield a spiroalkylated azlactone compound. The latter compound is then subsequently converted to the known 4-amino-6-fluorochroman-4-carboxylic acid or the novel (2R-methyl derivative thereof, both in the form of their hydrohalide acid addition salts, by employing acid hydrolysis and the intermediate spiro-amino acid hydrohalide salt is thereafter converted to the corresponding methyl or ethyl ester and resolved with  alpha -chymotrypsin to afford the desired (S)-methyl or (S)-ethyl ester. Treatment of either of these latter two esters with an alkali metal cyanate in an acid medium then effects conversion of same to the desired spiro-hydantoin ring compound. Alternatively, the spiro-amino acid hydrohalide salt can also be converted to the desired spiro-hydantoin ring compound in a known manner, involving a sequence of three reaction steps. The spiroalkylated azlactone compound of the instant invention, as well as the methyl and ethyl esters mentioned above, are themselves novel compounds and are valuable as synthetic intermediates in the process of this invention.
