The disrupter (16) includes an elongated hollow barrel (18) having a cylindrical inner chamber (20), a closed rear (26) end and an opened front end (22), the latter closed with a front frangible seal (38). A channel member (46) partly surrounds an intermediate portion of the barrel, and is securely attached thereto. A pair of recoil channels (76, 78) extend from the barrel inner chamber, radially outwardly and rearwardly through the barrel and the channel member, and are linked to rearwardly oriented recoil tubes (52, 54) which have opened rear end portions (60, 62) closed with rear frangible seals (64, 66). In use, a cartridge (90) including an explosive charge (88) is to be inserted in the barrel inner chamber at its rear end, and the barrel, recoil channels and recoil tubes (52, 54) are to be filled with water. The frangible seals (38, 64, 66) prevent the water from leaking out of the disrupter while it is positioned near a bomb to be deactivated. A trigger (36) is linked to the disrupter, and more particularly to the cartridge, to remotely detonate the explosive charge. Upon the explosive charge being detonated, a portion of the water is propelled and ejected at high velocity out through the barrel front end, rupturing the front frangible seal, to puncture the bomb outer shell and deactivate the bomb inner detonating components. Another portion of the water is redirected through the side recoil channels and recoil tubes, rupturing the rear frangible seals, to be ejected rearwardly out of the disrupter. The recoil created by the detonation of the explosive charge which ejects the water through the barrel front end, is at least partially counteracted by the water being laterally and rearwardly redirected to be ejected rearwardly out through the recoil tubes. The recoil tubes have at their rear ends (60, 62) transverse blades (73, 74) for wide angle dispersal of the fluid jet being ejected rearwardly.

The present invention provides a steam cleaning system comprising a housing and a steam generating system for producing a low pressure, superheated saturated steam. A steam dispensing system comprising a water reservoir and a pump feeding the water into a steam producing boiler, is coupled thereto for dispensing the steam from the system to at least one first outlet port. A cleaning solution dispensing system is provided, having at least one reservoir for a cleaning solution, and a pump system for dispensing a predetermined amount of a cleaning solution from said at least one reservoir to at least one second outlet port. The at least one first and second outlet ports are positioned adjacent one another, such that a mixture of cleaning solution and saturated steam at a low pressure and low volume of steam and cleaning solution is dispensed from the system. The present invention is particularly suited to clean objects off the floor, vertical surfaces such as glass, and small areas of floor. Because of the small volume of water and chemicals used, it can be used indoors, as well as mounted on mobile platforms such as trucks, buggies, utility vehicles, automatic floor scrubbers or the like. The system also provides for cleaning of roads, sidewalks, exterior structures, or for spot cleaning or cleaning of surfaces in difficult environments. The low pressure, superheated, saturated steam cleaning assembly of the present invention provides low pressure (10 Bar) operation, and relies upon superheated steam temperatures coupled with environmentally friendly chemicals as an abrasive force, thus avoiding any collateral damage usually caused by the high pressure output. The present invention only applies 3 to 10 gallons of water an hour, depending on the size of the machine, while a conventional high-pressure washer / steamer will use 240 gallons per hour.

A method for HIFU treatment of localized prostate cancer in a patient includes identifying the cancer locations in a patient's prostate; visually segmenting the patient's prostate into areas for analysis and treatment, where the section including the area of most aggressive cancer is determined to be the primary area. The primary area is subjected to a first full HIFU treatment for a period intended to ablate the cancerous tumor. HIFU treatment is then stopped on the primary area and the primary area is allowed to rest while simultaneously subjecting the next contiguous area of the patient's prostate to a first HIFU treatment to ablate any additional areas of suspected cancer in the next contiguous area. HIFU treatment is then stopped in the contiguous area. The primary area is then subjected to a second full HIFU treatment for a period sufficient to ensure the complete ablation of the cancerous tumor. The method further includes repeating alternating full HIFU treatment processes on subsequent contiguous areas of the patient's prostate to ensure the complete ablation of any cancerous tumors in the patient's prostate. The entire process is completed under one treatment of anesthesia.
