Abstract: A portable water filtration device including a holding chamber and a filtration chamber containing at least one filter media and configured to telescope with said holding chamber, a suction end adapter connected to the distal end of the holding chamber, and an outlet adapter coupled over the outlet end of the filtration chamber having a pair of opposite outwardly extending finger grips connected to a side wall of the cap section, wherein water is drawn into the holding chamber and then into the filtration chamber by a pumping action, and a pre-filter configured to be secured to the suction end adapter by a friction fit, and a channel extending through the adapter portion of the pre-filter configured to connect to a free end of the tubular member connected to the outlet adapter also by a friction fit to enable cleaning of the pre-filter by reverse flushing water through said pre-filter.

Abstract: A computer-implemented method for stratifying a patient with irritable bowel syndrome (IBS). The method comprises detecting the presence, absence, or abundance of multiple bacteria in a biological sample obtained from the patient to generate a patient microbiome profile; and operating a trained classifier on the patient microbiome profile to output a signal stratifying the patient with irritable bowel syndrome (IBS) into a first group or a second group. Stratification of the patient into the first group is indicative that the patient has a not significantly altered microbiome in comparison to the average microbiome not indicative of IBS. Stratification of the patient into the second group is indicative that the patient has an altered microbiome in comparison to the average microbiome not indicative of IBS.

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: 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: 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 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: Novel polynucleotides isolated from Lactobacillus rhamnosus, as well as probes and primers, genetic constructs comprising the polynucleotides, biological materials, including plants, microorganisms and multicellular organisms incorporating the polynucleotides, polypeptides expressed by the polynucleotides, and methods for using the polynucleotides and polypeptides are disclosed.

Abstract: A motor vehicle kinetic energy recovery system uses one or more cylinders of an internal combustion engine as the first or primary stage in a multi-stage high pressure air compression system, a compressed air storage system, compressed air operated drive train boosters and vehicle management electronics to provide cooperation between the air compression, storage and booster systems. The multi-stage, high pressure air compressor system is operable through engine compression braking allowing kinetic energy of a vehicle to be recaptured during retardation of vehicle speed.
