Abstract: THE PRODUCTION OF A SELECTIVELY PROTECTED N-ACYLATED DERIVATIVE OF AN AMINOGLYCOSIDIC ANTIBIOTIC     ABSTRACT OF THE DISCLOSURE         Aminoglycosidic antibiotic comprising a 6-0-(3"-aminoglycosyl)-2-deoxystreptamine optionally having a 4-0-(aminogycosyl) group, such as kanamycins, gentamicins, sisomicin, forms reversible complex with zinc cations by association of the zinc cations with some pairs of amino hydroxyl groups in the aminoglycoside, and the zinc-complexed amino groups are blocked from acylation.  Reaction of this zinc complex with an acylation reagent having an amino-blocking acyl group brings about acylation of the non-complexed amino groups to give an N-acylated zinc complex, namely a complex of zinc cation with an N-acylated aminoglycosidic antibiotic derivative.  Removal of zinc cations from N-acylated zinc complex yields a partially N-acylated amino-glycosidic antibiotic where 1- and 3"-amino groups are unprotected but all other amino groups protected with acyl group.  Further reaction of this partially N-acylated product with a certain alkanoic acid or N-formyl-imidazole results in preferential acylation of 3"-amino group without 1-amino group being acylated, affording a 1-N-unprotected and other N-fully-protected derivative of the aminoglycosidic antibiotic which is valuable to be 1-N-acylated with .alpha.-hydroxy-.omega.-amino-alkanoic acid for high-yield production of known semi-synthetic 1-N-(.alpha.-hydroxy-.omega.-aminoalkanoyl)-aminoglycosidic antibiotic.

Abstract: ABSTRACT OF THE DISCLOSURE       Hydrogen isotope (e.g. deuterium) exchange from liquid water to a gaseous halohydrocarbon (e.g. fluorform, CF3H-CF3D) is obtained at an operating temperature in the range 0 to 100°C using a catalytically active mass comprising a porous anion exchange resin in the hydroxide ion form and the enriched gaseous halohydrocarbon streams is decomposed by isotope selective photo-decomposition into a first, gaseous stream enriched in the hydrogen isotope, which is removed as a product, and a depleted gaseous halohydrocarbon stress, which is recirculated for enrichment again.  The catalytically active mass may, for example, be in the form of resin particles suspended in a fluidized bed or parked as resin particles between sheets wound into a roll.  One of the sheets may be corrugated and have open interstices to form a packing in a column which permits countercurrent gas and liquid flow past the resin.  Pre-ferably the wound sheets are hydrophilic to retard flooding by the liquid water.  The liquid water stream may contain dimethyl sulfoxide (DMSO) added as co-solvent.

Abstract: ABSTRACT        An integral snap hinge of plastic material is intended to be used, e.g., for container closures or vacuum formed packages.  At least two flexible joints extend-ing in the direction of the main geometric axis are provided between these two hinged members.  At least one of these flexible joints is constituted by a connecting element, which is flexibly linked to the hinge members by film hinges.  The film hinges diverge so that the con-necting elements widens along the main geometric axis.  The large or small ends of the two connecting elements may face each other.  The snap action is due to the fact that components of the snap hinge are resilient.  The spring action may be performed by the connecting elements and/or by walls of the hinge members.

Abstract: 46,960 GROUND FAULT CIRCUIT INTERRUPTER WITH      GROUNDED NEUTRAL PROTECTION     ABSTRACT OF THE DISCLOSURE         A ground fault circuit interrupter includes a differential current transformer sensing winding supplying input to an integrator which is reset to zero at the end of each half-cycle of AC line current.  A line-to-ground fault current will cause the integrator output to exceed a pre-determined limit value and produce a trip indication.  A saturable neutral transformer supplies a voltage to the neutral line and a reference current proportional to the neutral voltage to a comparator.  The peak value of the reference current is compared to the peak value of the sensing winding output.  A low resistance neutral-to-ground path causes the sensing winding output to exceed the refer-ence current and a signal to be added to the integrator input, thereby producing a trip indication which energizes an SCR to activate a solenoid.  Means are provided to pro-duce a positive feedback signal to insure a "hard" turn-on of the SCR upon receipt of a trip indication, the feedback means also including capability to "remember" a trip indica-tion at the end of a half-cycle near current zero, and to produce the positive feedback signal at the beginning of the next succeeding half cycle.

Abstract: CABLE TERMINATING TOOL                            ABSTRACT This invention concerns a tool for connecting a cable, particularly a flat cable, to a cable connector, particularly to a flat cable connector or the like.  The known termination tools often have relatively complicated adjusting mechanisms for centering the cable connector in relation to the center of the press and for adjusting the working height for the various types of connectors.  Finally, with the known tools, there is no possibility of visually monitoring the alignment of the cable conductors with the terminals during the mounting process. The present invention permits a cable connector, regardless of its total length or the number of contacts, to be automatically positioned precisely under the center of the press die by the action of pairs of symmetrically positioned ribs having sloping engage-ment surfaces.  The invention also permits the vertical position-ing of cable connectors of different total structural heights by simply reversing the orientation of the connector support. Finally, the invention offers the possibility of visually monitoring the positioning of the conductors during the mounting process through an optical prism.

Abstract: VELOCITY OPERATED STANDING VALVE      This application is a divisional of our copending appli-cation Serial No.  362,846,  for Velocity Operated Standing Valve, filed October 21, 1980.          ABSTRACT OF THE INVENTION    A standing valve for controlling fluid flow through a well flow conductor.  The standing valve allows for formation fluids to enter the flow conductor downhole and to flow in one direc-tion to the well surface.  The standing valve functions as a check valve to prevent fluids injected into the flow conductor at the well surface from flowing out the other end of the well flow conductor. The standing valve is operated by changes in the velocity of fluids flowing through the valve.  When the pressure of fluid injected into the flow conductor from the well surface exceeds a preselected value, an alternative flow path is opened within the standing valve to allow the injected fluid to flow in the other direction through the valve.

Abstract: SEMICONDUCTOR CROSSPOINT LINEARIZING ARRANGEMENT            Abstract of the Disclosure An arrangement for performing subscriber loop testing through a concentrator/expandor employing semiconductor crosspoints.  The crosspoints of the concentrator/expandor are relatively nonlinear when conducting currents less than a predetermined current and are relatively linear when conducting currents in excess of the predetermined current.  When tests are to be applied to a given subscriber loop which comprises a tip conductor and a ring conductor, two paths are completed through the concentrator/expandor to the tip conductor and two paths are completed through the concentrator/expandor to the ring conductor.  A linearizing source then transmits a current in excess of the predetermined current around the circuits formed by the two concentrator/expandor paths to each subscriber loop conductor.  Test signals are then applied to the subscriber loop by connecting such signals between the two paths to the subscriber ring conductor and the two paths to the subscriber tip conductor.
