A portable container for purifying drinking water GB2312175 Keith In Raymond Dalton, Roger John Cheeseman and Charles Sidney Dalton describe a portable container for purifying drinking water. It comprises a body portion for containing the drinking water, a filter for filtering the water and an air pump for delivering air to an ozone generator in order to produce a mixture of air and ozone. The mixture of air and ozone is delivered via a pipe to the drinking water in the body portion. This causes the drinking water and the mixture of air and ozone to pass through the filter whereby the filter filters the drinking water. The ozone purifies both the water and the filter i.e. kills the bacteria contained therein. The killing of the bacteria in the filter helps to regenerate the filter thus prolonging its effectiveness. The container may be in the shape of a jug or kettle. Date of Publication: 22 October 1997.

Water filtration
unit
In GB2312383 KX Industries L.P. describes a water treatment unit. It comprises a base and a disposable, plug-in cartridge i.e. filter housing.The filter housing contains a pair of hollow, cylindrical filters designed to treat water flowing radially through their walls. The filter hous-
ing and base have studs and sockets respectively. When the hollow studs are inserted into the sockets they form inlet and outlet channels. The filters are mounted so as to act in parallel, thereby achieving the advantage of a long, thin walled element in a configuration. compact There is also means provided for releasably securing the housing to the base member.
without damage to the filter body or other portions of the filter. In an alternative embodiment, the end cap may have a lip for engagement with recess. The filter can be used in oil, gas, water and geothermal wells. Inventor: Michael B. Whitlock. Date of Publication: 12 November 1997.
The releasable securing means consists of a key mounted on the housing and a latch mounted on the base to receive the key. The filter housing can be removed from the base by rotating an elliptical portion by 90°. This disengages the key from the latches. The water treatment unit might also be used in kitchens or bathrooms as a domestic water filtration unit. Inventor: Evan Ernest Koslow. Date of Publication 29 October 1997.
In GB2312858 William Myron Cravello describes a shaker screen assembly. Each removable compartment is provided with a removable hookless corrugated filter having no additional support backing which is secured between a perforated bottom of the compartment and a removable lid. Each lid is provided with a number of downwardly extending parallel blades which coincide with and engage valleys of the corrugated filters to seal and support the filters with their respective compartments. Each filter is sealed and supported at its front and rear edges upon removable corrugated lips. Removable common walls are provided between adjacent compartments, each wall having port holes which coincide with undulations of the filters.
Filter with a slidable cap for subterranean
end use
In GB2372856 Pall Corp. describes a filter for subterranean environments. It comprises a filter body containing a filter medium fitted around an inner support member. There is also at least one end cap connected to the filter body.The end cap comprises a first and a welded second sleeve together. The sleeves surround the inner support and a stopping unit which is positioned in a recess in the support.The first sleeve has a stopping surface which opposes the stopping unit to prevent movement of the sleeve. The stopping unit may be in the form of balls or split rings.There is also a sealing member to prevent particulate matter bypassing the filter body. The end cap may be capable of movement in a lengthwise direction of the inner support to enable the filter to undergo thermal expansion
Shaker
screen
assembly
Mounted in conventional shaker assemblies, these compartments are used to separate drinking fluid (for recycling) from shale and debris, with the solid output from the top of one screen becoming the input to the top of the next screen. For improved durability the corrugated filter is preferably made from three overlapping wire meshes of different sizes bonded together either with adhesive or by a plastic material (i.e. sheets or pellets of polypropylene) which is melted into the mesh. Date of Publication: 12 November 1997.
Separator for removing fine particulates from air In WP97/37746 Llewellyn E. Depew describes a separator for removing small particulates from an air stream. The separator includes a pneumatic separator with a relatively small filter element built inside the separator to remove particulates from the air stream down to as small as one micron.The pneumatic separator relies on a vortex effect and sudden changes in direction of the air flow to strip out most of the particulates. Because the very small particulates have insufficient mass to be dislodged from the air in this these particulates way, remain in the air stream and are carried to the filter element where they build up on the element. The build up is interrupted by the incoming air which flows aggressively around the element and strips parts of the build-up off the element. This ongoing random process can be supplemented if necessary by back flushing. Both the separated particulates and those stripped off the filter element accumulate in the separator for subsequent removal. Date of publication: 6 October 1997. Biofilters and device moistening
for
In WP97/37748 Stein G. Ahlqvist describes a process and device for socalled biofilters, in which polluted gases e.g. air, is made to pass through, and thereby be cleaned in a bed of bed media arranged in a It comprises container. measuring the moisture content of the bed and the supply of fluid, e.g. water, in order to maintain the desired moisture content. The moisture content of the bed is measured by means which are not in contact with the bed media. Date of Publication: 16 October 1997.
