Abstract: INVENTOR: Stephen L. Nickol 224 Pinehurst Road Wilmington, New Castle County State of Delaware 19803 TITLE OF THE INVENTION: "SINGLE STEP PREPARATION OF                         BLOCK COPOLYMER OF POLYAMIDES"             ABSTRACT OF THE DISCLOSURE     Process for forming block copolymer involves mixing dry salt of a prepolyamide and a molten melt-spinnable polyamide.  Mixture is heated to a temperature in the range of between from the melting point of higher melting component of the mixture to below amide-inter-change temperature of a blend of the melt-spinnable polyamide and the homopolymer which would result from the polymerization of the salt. Mixing and heating is continued until substantially all of the salt and the polyamide are converted into a block copolymer. The latter can be used to make fibers.  One example of a suitable salt is a 30203-6 salt.

Abstract: DEAD-FRONT ELECTRICAL CONNECTOR           Abstract An integrally molded housing has a dead-front base and a pair of side covers pivotally connected to it by web hinges.  The side covers fold about the web hinges to:  (i) force cord conductors into insulation displacement terminals affixed to the housing and thus wire the connector; (ii) safely enclose the wiring area; and (iii) lock the side covers to the dead-front base by the engagement of mating portions of the covers and base to prevent relative motion even should the web hinges fail.  The connector can have male or female contacts or both. It provides speed and convenience of wiring and assembly and ensures quality wiring by eliminatin the variability in workmanship associated with conventional stripping of conductor ends and screw tightening used for screw type terminals.

Abstract: ABSTRACT OF THE DISCLOSURE      This invention relates generally to improvements in an improved valve control system for syringe pumps.  Prior art syringe pumps are often overly complex and unstable or inaccurate in their valving and motor control systems.  The present invention overcomes these deficiencies by providing apparatus which repetitively and sequentially opens and closes a pair of intake and output I.V. tubes communicating with a syringe, the tubes alternating between opened and closed states, one tube always being open while the other is closed, by means of a pair of L-shaped pivotal tube pinchers, one pincher controlling each I.V. tube, each pincher being normally spring biased to the tube clamping shut-off state.  The tube pinchers are alternately pivoted to a non-clamping, tube-open posi-tion by a spring biased, intermittent motion, reciprocating slider bar under the control of a reversible, rotating cam, the cam being driven by the same motor as that used to drive the piston of the syringe through its fill and pump strokes.  A photoelectric sensor is responsive to the physical position of one of the tube pinchers and generates an electrical signal to control the direction of motor rotation and, hence, determines whether the syringe pump performs a fill stroke or a pump stroke.

Abstract: ABSTRACT The invention relates generally to a method for producing radioactive isotopes.  More specifically, the invention relates to an improved chromatographic extraction method whereby Technetium-99m of high yield and high purity is produced.  Technetium-99m which has a half life of six hours, is produced by the spontaneous radioactive decay of Molybdenum-99, which has a half life of 67 hours.  The user then separates the desired amount of Technetium-99m from the Molyb-denum-99 as his needs require.  Prior art separation methods are either non-specific or relatively inef-ficient.  Additionally, with most of the prior art methods, Technetium-99m is produced in the form of an aqueous solvent whereas production in a solventless, i.e. dry particulate form, would be more desirable for purposes of flexibility in the preparation of diagnos-tic reagents of desired radioactive concentration. According to the present invention, Technetium-99m is produced in a dry particulate form of high yield and high purity.  The method of the present invention com-prises the steps of eluting an adsorbant chromato-graphic material containing Molybdenum-99 and Techne-tium-99m with a neutral solvent system comprising an organic solvent containing from about 0.1 to less than about 10% water or from about 1 to less than about 70% of a solvent selected from the group consisting of aliphatic alcohols having 1-6 carbon atoms and separating the solvent system from the eluate whereby a dry, particulate residue is obtained containing Technetium-99m, said residue being substantially free of Molybdenum-99.

Spring biased elbows or hinges are provided in the damper levers to allow "breaking" of the levers at such time so as to avoid providing a strange feel to the pianist.          The rubber nature of the fitting prevents any noise at such time.
