A filter assembly includes a housing with an inlet and an outlet. The filter assembly also includes a tubular filter element located downstream of the inlet and upstream of the outlet and a sleeve element surrounding and blocking at least a portion of the filter element.

A grid cover for a grid of a filter system covers a strut of the grid. The grid cover may be removable. The grid cover may be configured as a clip and may be clipped on the strut of the grid.

A cartridge for a filtering device, includes a cylindrically arranged pleated cloth, the pleats being parallel to the generatrix of the cylinder, wherein the cylinder includes a non-pleated region which is to be placed across from a fuel inlet into the filtering device.

FLOW SEPARATOR SYSTEM IN MULTIFILTER UNITS composed of a number of bodies called flow separators, each of which is fitted around a filter and where each separator body comprises a support structure formed by a base, a number of rods and a cap, such that, along the said support structure, a flexible screen is fitted, with a helicoidal configuration, integrated with the movement of the support structure such that each flow separator body retains the dirt particles before they reach each filter, controlling the flow to be purified by each filter, redirecting the flows and preventing the flows between the different filters that make up the system from being mixed together.

An aggregate processing system, including a water source, and a vibrating screen device including a plurality of spray nozzles disposed above a screen for spraying wash water onto aggregate during aggregate processing. A strainer device is provided for removing particulate debris from a water wash stream flowing from a water source to the spray nozzles, the strainer device including a filter screen having an angled shape with a convex side facing the strainer inlet and fluid flow path. The strainer is configured to induce turbulent flow for separation of the particulates by gravity, with the filter screen blocking particulates above a given size. In this manner, particulates which may otherwise lead to clogging of the spray nozzles are removed from the wash water stream.

A filter device includes a housing with an end part and a side wall and containing an axially arranged array of filter elements, such as ceramic elements. An inlet in the end part supplies fluid to the filter elements and an outlet in the side wall is provided for transporting filtered fluid from the housing, the side wall of the filter device being provided with a cleaning duct for supplying cleaning fluid to the filter elements via the side wall. The cleaning duct 6 includes a distal channel portion 15 having a relatively small diameter D1 and a proximal portion 16 adjacent the side wall having a relatively large diameter D2. A number of partitions 36, 37 extend in the proximal portion from a position at or near the sidewall towards the distal channel portion 15 at an angle () to a center line 20 of the cleaning duct 6.

A grid cover for a grid of a filter system covers a strut of the grid. The grid cover may be removable. The grid cover may be configured as a clip and may be clipped on the strut of the grid.

The present invention is directed to a filter housing with a removable filter assembly having an elongated shell assembly, a removable head assembly, and a removable filter assembly. The shell assembly has an inlet section, an outlet section, and a filter assembly opening. The removable filter cartridge includes a top tube sheet, a bottom tube sheet and a plurality of filter cartridges. The filter cartridges provide the only fluid passage through the bottom tube sheet, which otherwise sealing engages a ring assembly within the shell assembly proximate to the outlet section.

The invention relates to a generator of electrical current by movement and induction by means of permanent magnets and resonant coils according to an envelope housing a circular solid element in the form of a rotor in which a variable magnetic flux is generated by incorporating thirty-eight permanent and rectangular magnets arranged such that they are radially aligned on the outer periphery of said rotor, and rotating inside a stator which has an annular shape and is hollow so as to carry out the cooling on the inside thereof, containing seventy-six idle coils which are regularly distributed and between which resonant capacitors and coils are alternated with non-resonant coils, arranged specifically three millimetres from the magnets, from which electrical current is generated with a very high efficiency.

The present invention relates to a water filter comprising: a water filter cartridge including a water filter cartridge body, a water filter cartridge outlet cap having a water filter cartridge outlet, and a water filter cartridge sealing cap. The water filter cartridge body in a hollow cylinder form with a central hollow space, one end of the water filter cartridge body is coupled with the water filter cartridge outlet cap so that communicating with the water filter cartridge outlet, and the another end of the water filter cartridge body is coupled with the water filter cartridge sealing cap. The water filter cartridge outlet in a hollow cylinder form protruding from one surface of the water filter cartridge outlet cap. The filter container for containing the water filter cartridge therein, wherein the filter container including a filter container body, a filter container cap, a filter container inlet, and a filter container outlet, wherein the filter container inlet and the filter container outlet arranged at a filter container body bottom. The filter container body having a filter container outlet cylinder hole provided at the filter container body bottom for receiving the water filter cartridge outlet, so that when water flows into the filter container through the filter container inlet will surround the water filter cartridge and flows through the water filter cartridge body into the central hollow space of the water filter cartridge body, and flows to the filter container outlet through the water filter cartridge outlet. The filter container body having ribs provided at an inner surface of the filter container body bottom to reinforce for the filter container body bottom and providing gaps placed between the inner surface of the filter container body bottom and the outer surface of the water filter cartridge outlet cap, so that replacements or miscellaneous uses of the water filter cartridges become impossible.
