Fluid filter

A substantially clog-resistant self-supporting fluid filter for attachment to a discharge tube or the like, comprising a cylindrically shaped grid open at both ends, having a first plurality of substantially parallel ribs crossed by and fastened to a second plurality of substantially parallel ribs at an angle to the first plurality of ribs.Spaces or apertures formed between each adjacent pair of parallel ribs provides passage for liquids to be filtered there through. A circular shaped stop member or snap-on cap having raised radial spacers or lugs is attached to one end of the filter, and prevents the end of the discharge tube slidably inserted into the filter from hitting the top surface of the snap-on cap. Snap-on cap has clips on the outer diameter of the top surface that securely attach the cap to the filter. The fluid filter further comprises a snap-on nipple insert for sealingly engaging the discharge tube and attaching the discharge tube to the filter. The snap-on nipple insert comprises a base, a ribbed body, a tubular body member, and a substantially cylindrical longitudinal opening along the axis of the insert to permit free flow of liquids and gases through the nipple insert. When the fluid filter is attached to the opening at one end of a discharge tube and placed in a fluid filled tank, the discharge tube can extend to the bottom of the tank to be emptied in order to draw any fluid remaining in the bottom of the tank.

Habitat friendly, pressure conversion, wind energy extraction

A habitat friendly, pressure conversion, wind energy extraction system is disclosed for safely extracting usable energy from wind. The system includes one or more shrouds or concentrator wings that convert the dynamic pressure of wind into relatively lower static pressure and thereby induces a vacuum that draws wind into a turbine centralized within the shrouds or concentrator wings. As such, the turbine impellor blades may be significantly smaller than the large diameter rotor blades of current popular designs and may be enclosed within the shrouds or concentrator wings that present themselves as highly visible objects and as such are easily avoided by birds in flight. The novel system in particular includes a device and method of airflow regulation than minimizes or prevents the stalling, or the generation of a turbulent flow of wind over or between the shrouds or concentrator wings. This stalling has been shown to occur when airflow is quickly accelerated by force of vacuum and drawn out of the turbine shroud which then mixes with and disturbs the otherwise smooth flow of wind over or between the shrouds or concentrator wings. The system may also include an aerobrake that responds quickly to protect the impellor blades or associated mechanisms from overspeeding or exceeding other design limitations under gusting or violent wind conditions. The system may also include a method of guiding elements of the system to orient appropriately into prevailing winds, and a method to support elements of the system, without unduly impeding the free flow of wind. Other advantages and objects are as well disclosed that increase safety and efficiency, increase installation potential, reduce costs and expenses, and minimize negative environmental impact.

Method for locating and controlling multilane free flow video vehicle

The invention relates to a multi-lane free flow video vehicle position and control method, the processes thereof are that: step 1, virtual coils are arranged in the visual field of a panoramic camera to form a detection area. Step 2, when a vehicle enters the detection area, a video detector starts an algorithm program to obtain the position of the vehicle. Step 3, a central processing unit starts a microwave communication system and an image snapshot system. Step 4, a logical comparison system judges whether the vehicle has electronic label information, if without, executing step 8. Step 5, the logical comparison system judges whether a vehicle license plate number in the electronic label information and the vehicle license plate number which is identified by a license plate recognition system are consistent, if not consistent, executing step 8 is. Step 6, the images of the vehicle which are snapshot are deleted. Step 7, toll transaction is done, and a transaction record is formed after the transaction. Step 8, the transaction record which is transferred to a background billing system is further treated. Step 9, returning to a main process. The method can achieve an electronic toll collection function in a multi-lane free flow mode through the accurate location for the vehicle and the coordination control for a system.
