Abstract: Minimizing the leaching of iodine through packaging containing organic iodophor solution, by introducing into the packaging an amount of additional iodide which minimizes leaching of the iodine through the packaging and stabilizes the iodophor solution therein. The iodophor is preferably polyvinylpyrrolidone iodine.

Abstract: The present invention relates to a method of making a threaded insert, a tool for carrying out the said method and the insert thus obtained which presents the form of a cylindrical tube provided with an external thread and an internal thread, and with a plurality of imprints directed towards the axis of the insert and located inside the remaining and intact cylindrical shape of the insert.

Abstract: A center-opening saw blade having an inner sawing edge is spanned or tensioned to provide an accurate, high quality cut by apparatus including inner and outer clamping collars between which an outer peripheral edge region of the saw blade is clamped, a spanner ring having an inner edge and an outer centering heel, the clamping collars being tightly affixed to the spanner ring with the clamping rings positioned in the centering heel with the inner edge of the spanner ring engaging an inner region of the saw blade to impart an initial stress thereto. A form ring is axially slidably mounted within the clamping collars and is slidable to engage an intermediate portion of the saw blade between the outer peripheral edge region clamped between the clamping collars and the inner region engaged by the inner edge of the spanner ring to impart a fine adjustment stress to the saw blade.

Abstract: In a heat exchanger having tubes arranged in latticed pattern in a frame and serving to conduct a medium for heat exchange and enclosed in a housing wherein the space defined by the housing and the frame is divided into a collector and a distribution chambers, each chamber being subdivided with a partition wall defining a further chamber, namely a collector and a distribution chambers respectively. These chambers intercommunicate through corresponding tubes to form separate flow paths for the medium for heat exchange. The heating or cooling medium is flowing through the exchanger transversely to the longitudinal direction of the tubes.

Abstract: For mining combustible minerals a plurality of boreholes are drilled in a gasifiable seam, e.g., in a coal bed, said boreholes 1 through 4 being intercommunicated by a number of gasification ducts. Then the combustible mineral is initiated to fire, and an oxygen-containing blast gas is blown through some of said boreholes into the gasification ducts, with the result that the generator gas is formed. Simultaneously a carbon- and/or hydrogen-containing blast gas is blown through other boreholes situated along the flow of the generator gas to enrich the latter with combustible ingredients. As a result some chemical reactions proceed under the effect of heat produced by the generator gas, whereby additional amounts of combustible elements are formed which add to the calorific value of the generator gas being withdrawn. The method is instrumental also in controlling the composition of the generator gas withdrawn by varying the ratio of the components of the blast gas enriching the generator gas.

Abstract: Respiration pacemaking valve apparatus adapted for use with apparatus for resuscitation such, for example, as a respirator, including a body member or housing defining a fluid flow passage, an inlet through which air or oxygen can be conducted into the fluid flow passage and wherein the body member is attached directly to a drug atomizer in a manner such that air or oxygen can be further conducted to the regulating valve assembly of a respirator or an outgoing connecting branch of other resuscitation apparatus. A spindle is disposed within the fluid flow passage of the body member which is provided with an elastic portion for opening and closing the fluid flow passage thereof in response to actuation of a trigger member pivotally mounted on the body member.

Abstract: The wet end of a fourdrinier paper machine includes a transversely disposed roll beneath the wire. The roll is shaped and mounted for rotation at a speed which is different from the speed of the wire to create pulses of negative pressure beneath the wire for drawing liquid from the web of fibers formed thereon. Also disclosed is a fin apparatus transversely disposed beneath the wire to create a wave of positive pressure thereunder to urge the formed web off of the wire.

Abstract: A corrosion-resistant weldable martensitic steel essentially consists of carbon 0.06 to 0.10 weight percent, chromium 15.1 to 16.5 weight percent, nickel 3.5 to 4.45 weight percent, silicon 0.10 to 0.60 weight percent, manganese 0.20 to 0.50 weight percent, at least one element selected from the group consisting of niobium 0.25 to 0.40 weight percent and zirconium 0.05 to 0.20 weight percent, at least one element selected from the group consisting of yttrium 0.05 to 0.20 weight percent, cerium 0.05 to 0.15 weight percent and lanthanum 0.05 to 0.15 weight percent, phosphorus not exceeding 0.025 weight percent, sulfur not exceeding 0.02 weight percent, copper not exceeding 0.20 weight percent, the remainder being substantially iron and unavoidable nonferrous impurities. The process for the manufacture of the steel comprises the steps of preparing a molten mass of said composition, pouring the molten mass into a mould and permitting it to solidify therein followed by cooling an ingot produced.

Abstract: The cholesterol blood level is lowered by administration of a spirogermanium (dimethyl, diethyl, dipropyl or dibutyl, diethyl or dibutyl being preferred).

Abstract: A sealed lead-acid storage battery of the Invention comprises a containers accommodating a lead dioxide cathode, a lead anode and an additional gas absorbing electrode formed from a mixture composed of an electrically conductive carbonaceous material and of a slightly water soluble quinoid compound having a low oxidation-reduction potential.

Abstract: The vibration motor comprises a concentrator of torsional vibrations, whose end face is in close contact with a rotor, and a piezoelectric cell unit adjoining the concentrator of torsional vibrations. Besides, the vibration motor is provided with a magnetic field source arranged under the rotor at the side of the concentrator of torsional vibrations and having a power sufficient to hold the rotor firmly against the concentrator end face, and with magnetic circuit. One part of the latter is movable, being fashioned as a disk with circumferentially spaced slots and rigidly connected to the rotor. The other part of the magnetic circuit separated from the first one by an air gap is stationary. It surrounds the magnetic field source and has peripheral slots identical to those of the movable disk and arranged opposite to them.
