A cover assembly is provided for preventing water infiltration into an in-floor receptacle fitting, such as a poke-thru fitting. The fitting includes an internal compartment which is accessible through an opening in the surface of the floor. The cover assembly includes a trim flange which overlies the floor opening. The trim flange supports at least one receptacle, such as a power receptacle, within the fitting such that the receptacle can be interconnected within the inner compartment with source cables that enter the fitting from below the floor, and can be interconnected from above with a connector such as a male electrical plug. A cover plate is mounted on the trim flange and overlies the receptacles carried by the fitting. The cover plate includes a plurality of access doors. Each of the access doors is movable between a first position at which it overlies an associated receptacle to prevent access thereto and a second position at which the associated receptacle is exposed and accessible from above. A first seal member interposed between the cover assembly first and second portions and adapted to seal against water infiltration therebetween. The first seal is in the form of a planar gasket which is sandwiched between the cover assembly first and second portions. The first seal overlies the receptacles and at least the portions of the trim flange which surround the perimeters of the receptacles. Access openings in the first seal provide access to the receptacles. Ribs extend upwardly around the perimeters of the openings and form an abut against the bottoms of the access doors when the doors are at their closed positions. The interference fit between the ribs and the access doors seals against water infiltration therebetween and into the fitting. The first seal further includes a downwardly extending rib which engages in a reciprocal groove formed in the trim flange around the perimeter of the receptacles. A second seal, in the form of at least one compressible gasket, extends around the perimeter of the floor opening and is adapted to be compressed between the cover assembly first portion and the floor's surface when the first portion is connected to the fitting.

A non-metallic floor box for use in electrical in-floor power and communication distribution systems includes a plurality of sets of vertically aligned indexing teeth formed in the interior of the housing side wall. An adapter ring is sized for insertion into the housing interior for supporting an activation kit above the housing interior compartment. The adapter ring has flanges extending from its periphery which are positioned to reciprocally mate with the vertical rows of teeth when the adapter ring is inserted into the housing interior compartment. The flanges and teeth are constructed to permit the ring to be inserted into the housing but to restrict its removal from the housing after its insertion therein. An activation cover is securable to the top of the adapter ring and extends beyond the perimeter of the side wall to limit the distance the adapter ring can be inserted into the housing. The floor box accommodates dual services through the use of two sets of parallel aligned conduit hubs and a divider which is insertable into the housing interior between the two sets of conduit hubs. The closed top of the housing acts as a concrete cover during the pouring of the floor, and as a temporary debris cover after it is cut off but prior to activation of the floor box. Gradient markings on the interior of the floor box provide a quick and accurate measurement of interior floor box volume for inspection and building code compliance.

Systems for aerating soil are provided. In this regard, a representative system includes: a plurality of aerating members, each of the aerating members having circumferential ends, longitudinal end portions, an aerating portion and aerating stud members, the end portions of the aerating members being angled with respect to the aerating portion; and a plurality of aerating stud members extending from the aerating portion of the aerating members; the aerating members being configured such that a circumferential end of a first of the aerating members attaches to a corresponding circumferential end of an adjacent one of the aerating members.

An exemplary embodiment comprises a plurality of aerating members with each aerating member having two opposing end portions, an aerating portion, an inner surface, and an outer surface. The end portions of the aerating members being angled with respect to the aerating portion. A plurality of linking members are moveably coupled with fasteners to the end portions such that an alternating series of linking members and aerating members form a loop of such members for attaching to a tire. A plurality of stud members are attached to the aerating portion of the aerating members.

摘要:
A method and apparatus for synchronizing streaming media with multiple output devices. One or more media servers serve media streams to one or more output devices (i.e., players). For playback synchronization, one output device is the “master”, whereas the remaining output devices are “slaves”. More data is requested from the media server by the “master” device to maintain a nominal buffer fill level over time. The “slave” devices receive streamed data from the media server at the rate determined by the master device's data requests, and the average rate of data flow over the streaming network is thus controlled by the frequency of the single “master” device's crystal. “Slave” devices make playback rate corrections to maintain respective buffer fill levels within upper and lower threshold levels. For slow networks, each media data packet timestamp is calculated from the time the master's buffer reaches nominal level.
