Abstract: An apparatus for the removal of mercury and other harmful substances from effluents produced in dentist offices is described. The apparatus involves a series of inclined plates upon which mercury reducing bacteria are present, and a subsequent alkaline pH precipitation chambers and an ion exchange chamber.

Abstract: A reclosable bag having a bag interior and a bag opening, the bag interior comprising: a sealing section; an air-flow section configured to permit air flow through the air-flow section; and an air access interface positioned between the air-flow section and the sealing section, and configured to permit fluid communication therebetween; the bag further comprising: an openable closure configured and positioned to open and close the bag opening, the sealing section being positioned between the closure and the air-flow section; and a valve configured and positioned to permit air to be removed from the bag interior through the valve so as to create a negative pressure in the bag interior relative to an exterior of the bag; the sealing section being configured such that, when there is the negative pressure and the closure is closed, air is blocked from leaking from the exterior through the closure and sealing section to the air-flow section.

Abstract: An in-ear monitor system facilitates stereo depth perception using microphones at each ear, minimizes occlusion effects, and provides a digital platform for both audio digital signal processing and wireless transmission.

Abstract: An in-ear monitor assembly includes an internal microphone to facilitate a bidirectional voice communication channel.

Abstract: An in-ear monitoring system transmits right- and left-channel audio data for one or more in-ear playback devices to create a first person acoustic environment for one or more third persons.

Abstract: Methods and apparatus for the installation of VIV suppression during the S-Lay installation of a subsea pipeline. A locking member will be interposed between a pipe and a fairing rotatably mounted on the pipe, sufficient to bias the fairing against rotating. Upon marine application, the locking member will degrade, thereby releasing the fairing.

Abstract: A reclosable bag, comprising: a bag portion defining a bag interior and a bag opening, a means for opening and closing the bag opening, the means comprising (i) opposed interlocking features along the bag opening, the interlocking features being sized and shaped to form a seal when engaged, and (ii) a slider in the bag opening, between the opposed interlocking features, to engage and disengage the interlocking features as the slider moves, the slider being further configured to seal the bag opening when positioned at one end of the bag opening, a passageway in the slider, to provide access between the bag interior and an area outside of the bag, and a means for selectively opening and closing the passageway, wherein, upon moving the slider to the end of the bag opening and sealing the bag opening, access may be selectively provided between the bag interior and the area outside of the bag through the passageway.

Abstract: Methods for remotely installing vortex-induced vibration (VIV) reduction and drag reduction devices on elongated structures in flowing fluid environments. The devices installed can include clamshell-shaped strakes, shrouds, fairings, sleeves and flotation modules.

Abstract: An advertising panel system for a conveyor of the type comprised of a series of substantially identically shaped plates which move in a closed path. The system includes a plurality of advertising panels having substantially the same shape as the conveyor plates. Each panel includes a base carrier sheet having a lower surface and an upper surface, a transparent cover sheet having a lower surface and an upper surface and an advertising sheet interposed between the base carrier sheet and the transparent cover sheet. An adhesive on the lower surface of the base carrier connects the advertising panel to the conveyor plate. A plurality of apertures pass through the three sheets of each panel and connectors secure the sheets together. The connectors are comprised of a T-nut that passes upwardly from the lower surface of the base carrier sheet and a screw that passes downwardly through the upper surface of the cover sheet and is threaded into the T-nut.

Abstract: This invention relates to a release modifier composition comprising an alkenyl functional polyorganosiloxane and a branched olefin. This invention further relates to the use of the release modifier composition in silicone release coating emulsions and solventless silicone release coating compositions. The silicone release coating compositions of this invention are useful in release pressure sensitive adhesives from a variety of substrates.

Abstract: This invention relates to a coated substrate obtained by a method comprising (I) applying a silicone emulsion composition to the surface of a substrate wherein the silicone emulsion composition comprises (a) an alkenylated silicone resin, (b) an alkenyl polydiorganosiloxane, (c) a silicone resin having SiH groups, (d) water, (e) a polyorganohydrogensiloxane, (f) an unsaturated organic monomer, (g) a hydrosilylation catalyst, and (h) an emulsifying agent. Separation of a laminate formed from a substrate coated with said emulsion release coating composition and a adhesive coated article requires a relatively high delamination force.

Abstract: An emulsion composition is described which comprises (a) an alkenylated silicone resin, (b) an alkenyl polydiorganosiloxane, (c) a silicone resin bearing SiH groups and (d) water. The emulsion composition may be combined with a precious metal catalyst to provide an emulsion release coating composition. The emulsion release coating composition may be applied to a substrate, for example paper, and cured thereon to provide an adhesive coating. Separation of a laminate formed from a substrate coated with said emulsion release coating composition and a adhesive coated article requires a relatively high delamination force.

Abstract: An emergency locking passenger seat belt retractor is fitted with a pyrotechnic pretensioner actuator (221) which acts via a cable wound on a drum (213), the drum being located on frangible supports in a clutch housing and having internally formed cam surfaces which can act upon frangibly supported intermediate rollers (215) to displace them generally radially inwards to drivingly engage a part of the webbing reel to tighten the belt. Advantageously the drum and the locking rollers are supported on frangible pegs moulded with shim or plate members (222a, 222b), disposed on each side of the drum (213).

Abstract: Progress for preparing a catalyst for hydrosilylation reactions which comprises reacting (A) a rhodium complex Rh(R.sub.2 S).sub.3 X.sub.3, in which R represents alkyl and other specified hydrocarbon groups and X represents Cl or Br with (B) an organohydrogen polysiloxane in the presence of (C) an organosiloxane having silicon-bonded vinyl or allyl groups. The ratio of silicon-bonded hydrogen atoms provided by (B) to each Rh atom provided by (B) is in the range from 0.5:1 to 6.0:1.The invention also includes the use of the catalyst for reacting .tbd.SiH with .tbd.Si Alkenyl especially in compositions for the treatment of substrates such as paper and plastics.
