Abstract: A filter system having a filter bed for filtering water or wastewater, where the filter bed is periodically washed between service runs by directing washing liquid and washing gas upwardly through the filter bed. The filter system includes a filter bed and at least one flume. The flume is in fluid communication with the filter bed. Preferably, the flume is configured such that no washing liquid and washing gas interface is present in the flume. The flume may be configured such that during washing of the filter bed between service runs the flume receives a washing gas and directs the washing gas upwardly through the filter bed to assist in cleaning the filter bed between service runs. The flume may further be configured such that during washing the only liquid directed from the flume to the filter bed is residual liquid that may be present in the flume from a prior service run.

Abstract: A surgical obturator comprising an elongate shaft extending along an axis between a proximal end and a distal end, and a bladeless tip disposed at the distal end of the shaft having a conical surface forming proximally into an outer surface, the outer surface extending distally to a blunt point and having a pair of side sections. The side sections extend from the blunt point radially outwardly with progressive positions proximally along the axis. The conical surface facilitates insertion of the obturator with a reduced penetration force and minimizes tenting of the body wall. The conical surface further facilitates separation of different layers of the body wall and provides proper alignment of the tip between the layers. The surgical obturator may be constructed from a disposable or reusable material such as a metal or an autoclavable polymer.

Abstract: A holder for charts having two transparent sheets, a connecting mechanical hinge and non-ferrous latching devices. The chart holder is sized to hold aeronautical charts and related flight planning documents. The hinge allows the two transparent sheets to be opened at least 180 degrees where the charts and documents can easily be place therein. The two sheets are able to close together, clamping the charts and documents between them. The two sheets are kept together by the latching devices. The transparent sheets provide an erasable writing surface where the pre-flight plans and in-flight data can be drawn and written with a non-permanent marker, thus protecting the documents enclosed. The chart holder also provides for the storage of the non-permanent marker. The chart holder can easily be opened with one hand to allow for repositioning of documents in flight. The transparent sheets have a tab allowing for an offset tab arrangement to allow for quick identification between multiple chart holders.

Abstract: The present invention relates to an apparatus that controllably allows the relative rotation between structures, such as a gimbal and a structure to which it is mounted. According to one aspect, the apparatus includes a twist capsule assembly with internal stop mechanisms that controllably prevents the amount of clockwise and counterclockwise rotation with respect to a rotation axis. According to another aspect of the invention, by limiting the amount of relative rotation, other means of communicating power and signals between the structures can be used, thus avoiding or reducing the limitations imposed by conventional slip ring assemblies. According to yet another aspect, the invention includes techniques and structures for allowing conventionally shielded cables and wires to be used in place of slip rings, while allowing for rotation between structures, thus even further improving the communication of power and signals between structures.

Abstract: A container closure assembly that includes a base that is adapted to be connected to a container, a spout extending upwardly from the base, and a cap removably secured on the spout. The spout defines an interior and includes a nozzle, the interior of which is spanned by a membrane that includes at least one score line defined therein. The cap includes a ring depending from and frangibly connected thereto, and includes a puncturing mechanism depending downwardly from a top thereof. Rotation of the cap in a first direction breaks the frangible connection between the cap and ring and causes the puncturing mechanism to puncture the membrane. In a preferred embodiment, the membrane includes a pair of intersecting score lines that tear when the membrane is punctured. In another preferred embodiment, the container closure assembly includes a leash that connects the cap and ring and that has a thickness and a width.
