Abstract: ABSTRACT            "MONOCLONAL ANTIBODIES TO HUMAN IMMUNE INTERFERON"           Disclosed are monoclonal antibody substances specifically immunologically reactive with native and recombinant human immune interferon ("IFN-.gamma.") and with polypeptides having amino acid sequences substantially duplicative of sequences extant in IFN-.gamma.. In a presently preferred embodiment, antibody substances are produced by new mouse-mouse hybridoma tumor cell line A.T.C.C. HB 8291 and are immunoreactive with native IFN-y, with recombinant IFN-.gamma. and polypeptide analogs thereof, and with a nonadecapeptide whose amino acid sequence dupli-cates that of the final nineteen amino acid residues of the carboxyl terminal of IFN-.gamma..  These preferred antibody substances, while displaying high affinity for IFN-.gamma., do not neutralize antiviral biological activity of the interferon.  They are usefully employed in the detection, quantification and affinity purification of IFN-.gamma. and IFN-.gamma. analogs as well as in investigations relating to the mode of biological action of IFN-.gamma..

Abstract: ABSTRACT OF THE DISCLOSURE               "Safety Device for Water Pipes"       The safety device makes it possible to cut the water supply off quickly when there is a very low flow of water such as occurs when there is a leak, to cutt off the water supply after predetermined time with normal water consumption, and to cut the water supply off very quickly when a certain pre-determined maximum flow is exceeded as would occur with a fractured pipe. The safety device is automatically returned to its initial position when the water consumption is stopped and the shut off is first indicated by a significant reduction in flow. The device can also be manually returned to its initial position after a shut-off.     FIG. 1

Abstract: ABSTRACT      A method for manufacturing liquid steel from highly concentrated iron ore concentrates which may contain phosphorous is described.  The method comprises producing a charge material by sintering a mixture comprising substantially the concentrate and basic slag-forming agents including CaO and MgO.  The composition of the mixture is adjusted so that the charge material includes CaO in an amount of at least 35% of the total weight of the non-iron oxide content of the charge material, and CaO and MgO in a total amount of at least 55% of the total weight of the iron oxide content of the charge material.  The composition exhibits a weight ratio of CaO : MgO of at least 1.3.  The charge material, which may be combined with other charge material, is reduced in solid phase to form sponge iron having a degree of metallization of at least 80%, and the sponge iron, which may be combined with another iron-bearing material, is smelted in a steel furnace under such conditions that an iron oxide content of at least about 5% by weight is maintained in the slag formed.  The resultant liquid steel and slag are separated.

Abstract: ABSTRACT OF THE DISCLOSURE    A molded sliding bar buckle of the type comprising a strap retainer bar slidably mounted on an open rectangular connector frame having a grip base and a connecting bar on opposite sides of the strap retainer bar.  The strap retainer bar includes a central strap engagemnt portion for retaining theraround one end portion of a strap and having on its back a sloped flat surface facing away from the grip base.  The sloped flat surface has an upper end disposed adjacent to the connecting portion and a lower end disposed adjacent to the grip base, the upper end lying in a plane extending through a center of the thickness of the strap engagement portion.  With this construction, when the strap is longitudinally tensioned with its one end portion looped around the strap engagement portion, a tensioning force is transformed substantially into a force or a vector acting on said plane in a direction to tend to move the strap retainer bar linearly toward the grip base.  A component of the tensioning force which acts on the strap engagement portion to rotate the strap retainer bar is substantially negligible.  Thus, the strap end is held firmly against displacement.

Abstract: WATER-SCAIE-INTEGRATED ASSEMBLY Abstract The standard silicon wafer of a conventional wafer-scale-integrated assembly is doped to render it highly conductive.  Additionally, a conductive layer is formed on the bottom of the wafer.  The bottom-side layer-forms an easily accessible ground plane of the assembly. Moreover, this layer and the conductive silicon constitute one plate of an advantageous wafer-size decoupling capacitor.  A nearly continuous power layer and a relatively thick layer of silicon dioxide on the top side of the assembly form the other elements of the decoupling capacitor.  Additionally, the nearly continuous power layer constitutes an effective a-c ground plane for overlying signal lines.

Abstract: AZB/dmc ABSTRACT OF THE DISCLOSURE     A catheter for delivering radiant energy, such as a laser beam, is used in a technique to controllably apply the radiant energy in a patient's body, such as in a blood vessel.  The radiant energy is applied in a manner which erodes biological material and may be used to drill through vascular obstructions.  The catheter emits the radiant energy from its distal end in a pattern which defines a relatively small working region in which the energy density level is sufficiently high to remove the biological material.  The energy distribution is substantially uniform across the beam. Distally beyond the working region, the energy density of the beam decays sharply so that biological material beyond the working region is not removed. Biological material is removed in very limited layer-like regions and in a manner in which a distally propogated segment of the beam will not have sufficient energy density to puncture the blood vessel wall.  The catheter is a of elongate flexible tubular construction having a fiber optic wave guide extending through the lumen of the catheter.  The distal end of the optical fiber terminates within the catheter and is secured in alignment with an optical system at the distal end of the catheter.
