  • Publication number: 20210280337
    Abstract: A stretchable conductor includes a substrate with a first major surface, wherein the substrate is an elastomeric material. An elongate wire is on the first major surface of the substrate; the wire includes a first end and a second end, and further includes at least one arcuate region between the first end and the second end. At least one portion of the arcuate region of the wire in the region has a first surface area portion embedded in the surface of the substrate and a second surface area portion unembedded on the substrate and exposed in an amount sufficient to render at least an area of the substrate in the region electrically conductive. The unembedded second surface portion of the arcuate region may lie above or below a plane of the substrate. Composite articles including a stretchable conductor in durable electrical contact with a conductive fabric are also disclosed.

  • Patent number: 10358248
    Abstract: A converter converts an existing bulk bag unloader to a bulk cargo receiver that eliminates the use of bulk bags. The converter enables the unloader to receive a continuous feed of bulk cargo without any interruptions such as those needed to unload emptied bulk bags and reload the unloader with full bulk bags.

  • Patent number: 10160152
    Abstract: A long fiber extrusion apparatus applies a polymer melt to a length of fiber using a die and an extruder where the length of fiber is directed to the die through a glass tube. The transparency of the glass tube enables viewing of the fiber as it is directed through the glass tube to monitor for any difficulties or problems encountered by the fiber passing through the glass tube. The glass interior surface of the glass tube reduces friction between the fiber and the glass surface and thereby reduces abrasion of the fiber and dust produced from abrasion of the fiber inside the glass tube.

  • Publication number: 20170020318
    Abstract: A beverage container has two main components: a drinking container and a chilling container. The chilling container is filled (or prefilled) with a chilling agent and placed in an environment suitable for freezing of the fluid. The chilling container is then coupled to the drinking container and the chilling container will chill the beverage contained within the drinking container. Flow restrictors within the chilling container prevent the frozen material from rising into the drinking container. The drinking container and chilling container are both designed to be reusable.

  • Patent number: 9068269
    Abstract: Aldehydes useful as H2S sulfide scavengers may be corrosive to some metals such as steel, iron and aluminum, but the corrosive effect of the aldehydes may be mitigated by employing a corrosion inhibitor selected from the group consisting of a di-basic soluble phosphate salt, a tri-basic soluble phosphate salt, a phosphate ester, a thiophosphate ester, a thioamine, a Mannich Reaction Product, and combinations thereof.

  • Patent number: 8894398
    Abstract: A modular plastic extrusion apparatus has several component parts. The design of the integration of those parts into a modular extrusion system is unique. Said design allows for rapid assembly, testing, disassembly and placement into production of extruded plastics. This modular plastic extrusion apparatus has several components with replaceable counterparts that, after one product line of a particular color has been extruded by the apparatus, enable the component parts used to produce the particular color extrusion to be removed from the apparatus and replaced with their clean counterparts to continue producing an extrusion product line of a different color while the removed components are cleaned off line.

  • Patent number: 8149879
    Abstract: A method of data transmission according to one embodiment of the invention includes encoding a set of data values to produce a corresponding series of ordered n-tuples. The method also includes transmitting, according to the series of ordered n-tuples, a plurality of bursts over a plurality n of frequency bands. Specifically, for each of the plurality of bursts, a frequency band occupied by the burst is indicated by the order within its n-tuple of an element corresponding to the burst. A bandwidth of at least one of the plurality of bursts is at least two percent of the center frequency of the burst. Information is encoded into a polarity of at least one of the plurality of bursts.

  • Publication number: 20110177986
    Abstract: It has been discovered that carbonate powders and bicarbonate powders are useful to increase the pH and corrosion resistance of high-density brines, such as zinc bromide brines, without significantly reducing their densities. The carbonates and/or bicarbonates should be water-soluble and may be sodium, potassium, magnesium and/or ammonium carbonates and/or bicarbonates and the like. The carbonates and/or bicarbonates are easily added in powder or other finely divided solid form and are completely dissolved in the brine prior to pumping the brine into a subterranean formation.

  • Patent number: 7655158
    Abstract: The corrosion inhibitor blend of at least one corrosion inhibitor base (which may be a Mannich reaction product), a solvent selected from the group consisting of C1 acids and ester and salt derivatives thereof, and optionally a surfactant, has been found to be effective as a corrosion inhibitor for metals in acid media, particularly fluids containing halogen acids. The corrosion inhibitor has improved performance over similar or identical corrosion inhibitor compositions where an alcohol such as methanol is used as a solvent. Suitable, non-limiting possibilities for the solvent include, but are not necessarily limited to formic acid, formate salts, methyl formate, ethyl formate, benzyl formate, formate salts of amines, inorganic formate, and mixtures thereof.
