摘要:
The Removable Bottom Founded Structure (RBFS) is an offshore platform for petroleum drilling and producing operations which is deployed in waters with severe weather and iceberg conditions. The structure is normally held down by gravity, but during the deballasting procedure a hold-down system is employed to keep the platform on the subbase until site evacuation. The system that is used to hold the platform down onto the subbase is located where the platform meets the subbase. It operates on the principle of hydrostatics. On the underside of the columns, there are multiple chambers which may be evacuated by pumping and which are vented to the outside atmosphere. Flexible seals that define these chambers are positively engaged by water to create a fluid-tight seal so that no seawater will enter the evacuated chambers. The reduction of the buoyancy forces will hold the platform onto the subbase until such time as the platform is totally deballasted. Once that has occurred, the hydrostatic hold-down system is disengaged and the platform will quickly rise to the surface.

The spinning rims for a bicycle include a spinning rim assembly having a wheel with a wheel hub, a first connecting member operatively connected to the wheel hub by a bearing assembly. The bearing assembly configured to provide independent rotational motion between the first connecting member and the wheel hub. A spinning rim is centrally disposed within the wheel and extends generally outwardly from the first connecting member, wherein the bearing assembly allows the spinning rim to rotate independently of the wheel when a bicycle is in motion and when the bicycle comes to a stop the spinning rims may continue to freely rotate by inertia.

An electronic device for use in a health care setting has a rigid enclosure assembly formed by a rigid shell and a rigid printed circuit board carrying circuitry for operating the device. A switch dome layer and an overlay are independently attached to the device but not to each other, whereby the overlay may be removed without disturbing the dome layer and a better tactile response is achieved.

A security apparatus is disclosed which provides for a cargo asset monitoring and tracking capability. The security apparatus may contain a physical locking function which provides a physical deterrent to an attached item such as a shipping drum. A microcontroller is provided within the security apparatus which monitors and coordinates locking/unlocking functions of the security apparatus, monitors an associated sensor to detect alarm conditions, monitors information from an RF transceiver with respect to proximity alerts and monitors information from one or more sensors incorporated within the security apparatus, the sensors providing information which may indicate tampering or damage to the cargo. The security apparatus is able to provide an audible alarm as well as communicate with a remote monitoring station upon detection of an alarm condition. A tracking system and process of monitoring and controlling the security apparatus from a remote location are also disclosed.
摘要:
Enamel insulation is stripped from a wire 1 by abrading the enamel coating with a pressurized stream of particles such as baking power, sodium bicarbonate. The particles chip off the relatively brittle coating, while the softer underlying wire is not harmed. The wire 1 passes through a chamber 4 and nozzles 18 direct the particle stream onto the wire 1. The chamber is evacuated at an outlet 34 to draw waste particles from the chamber 4. In another embodiment, the particle stream itself is directed through an outlet at the opposite side of the wire to entrain the waste particles and exhaust them from the chamber.

摘要:
Disclosed are quaternary ammonium salts containing non-halogen anions (e.g., quaternary ammonium carbonates, bicarbonates, and mixtures thereof) as anti-corrosive agents. The invention relates to a method for inhibiting the corrosion of metal surfaces by applying a composition containing one or more quaternary ammonium carbonate or bicarbonate. The disclosure is also directed to anti-corrosive coatings for metal substrates containing these compounds, to metal substrates having these anticorrosive coatings, and to aqueous cleaning solutions containing these compounds.

Disclosed are quaternary ammonium salts containing non-halogen anions such as carbonates, bicarbonates, phosphates, glycolates and mixtures thereof as conversion coatings or additives imparting anti-corrosive properties to paints. The invention relates to a method for inhibiting the corrosion of metal surfaces by applying a composition containing one or more quaternary ammonium carbonate or bicarbonate. The disclosure is also directed to anti-corrosive coatings for metal substrates containing these compounds and to metal substrates having these anticorrosive coatings.
