Abstract: A portable device for filtering and purifying water comprised of an outer chamber and an inner chamber that is slidable within a section of the outer chamber, and a small pore size pre-filter, whereby water is drawn through the pre-filter into the first container section of the outer chamber where it is isolated and treated with a disinfectant agent, then is drawn out of the first container section and into the second container section, and then into the inner chamber, where it is passed across another filtering material such as an activated carbon bed, removing any remaining contaminants before the potable water exits through a mouthpiece.

Abstract: A portable water disinfecting and purification apparatus comprising a first chamber into which water to be purified may be drawn by suction or negative pressure, a second chamber into which the water from the first chamber can be forced by a pumping action or positive pressure, whereby the water is initially passed across a pre-filter secured over the inlet to the first chamber and having a very small pore size and an inner cavity in which a disinfecting agent is place to filters most contaminants before the water is drawn into said filtering device, and once in the first holding chamber the water is isolated and may be further treated with a disinfectant agent, and then is passed though at least additional filtering substance including an activated carbon or nano-filter.

Abstract: A portable water disinfecting and purification apparatus comprising a first chamber into which water to be purified may be drawn by suction or negative pressure, a second chamber into which the water from the first chamber can be forced by a pumping action or positive pressure, whereby the water is passed across a micro-filter positioned within a section of the second chamber through which water can be forced by said pumping action to an outlet for purified water.

Abstract: A device for dispensing bath and shower salts, oils and other additives into a shower water stream, which device utilizes an improved valve arrangement in which the path of the water into the additive container may be partially or completely blocked or completely open so that the amount of additives inserted into the water stream is more easily controlled.

Abstract: An arrangement is provided to relieve the wear in a vibration type indicator for a valve by providing a stress relieving opening behind one of two temporarily interengaging structures formed of a groove and a projection particularly in a plastic construction.

Abstract: An adapter tube for strengthening pipe connections between a supply pipe and an apparatus mounted to the supply pipe having a first outwardly tapered section, a second inwardly tapered section and a threaded female adapter wherein when the adapter is threadably secured to a supply pipe a frictional fit between the supply pipe and adapter is created. An O-ring may also be provided on the first tapered section which is modified to have a steeper angle to improve the water tightness of the device.

Abstract: A protective covering device having a weather-resistant sheet of material wound about a spring-loaded roller, which material may be extended off the roller and over an object to be covered in a relatively easy manner, and which material may then be spring-assisted back onto the roller during the uncovering of such object. The spring-loaded roller is positioned with a housing that is either anchored to the same surface on which the object to be covered is positioned, or is mountable to a vertically-oriented surface located near one end of the object to be covered. The opposite end of the cover has a four-point multiple curved contour configuration to provide better wrapping both on the storage roller and about the end of a vehicle to be covered. Elastic attachments between the cover and the draw bar serve to draw it over the vehicle and provide convenient and efficient wrapping of the cover about the end of the vehicle.

Abstract: A protective covering device having a weather-resistant sheet of material wound about a spring-loaded roller, which material may be extended off the roller and over an object to be covered in a relatively easy manner, and which material may then be spring-assisted back onto the roller during the uncovering of such object. Simple air buffered deceleration of the cover as it settles over the object to be covered is designed into the apparatus of the invention.
