20090148570 | Hydrogen elimination and thermal energy generation in water-activated chemical heaters - Less hazardous methods for generating thermal energy for heating water, medical supplies or comestible products using improved flameless chemical heaters/flameless ration heaters by novel chemical or electrochemical means, each capable of suppressing the generation of hydrogen gas. Remote unit self-heating meals may be more rapidly heated by forming a reaction mixture comprising magnesium or a magnesium-containing alloy, and a hydrogen eliminator or suppressor, and introducing water to react the reaction mixture and generate a more rapid release of thermal energy sufficient to effectuate a more accelerated temperature rise and more rapid heating of medical supplies, water, rations or other comestible substances while simultaneously suppressing or eliminating the generation of potentially hazardous hydrogen. | 06-11-2009 |
20100136186 | HYDROGEN ELIMINATION AND THERMAL ENERGY GENERATION IN WATER-ACTIVATED CHEMICAL HEATERS - A hydrogen suppressing, flameless, heat generating chemical composition including magnesium or a magnesium-containing alloy, a hydrogen suppressor or eliminator, particulate carbon, a metallic salt including a cation and an anion and water. The anion is selected from the group consisting of silicate, carbonate, bicarbonate, phosphate, borate, perborate, percarbonate, perphosphate, persulfate, nitrate, nitrite, ferrate, permanganate, and stannate and combinations thereof. The magnesium or magnesium-containing alloy, hydrogen suppressor or eliminator, particulate carbon, metallic salt and water are each present in a proportional amount to generate sufficient heat to heat water, medical supplies and/or consumable rations. | 06-03-2010 |

20090045383 | Lifting assist device - Disclosed herein is a device for lifting an article comprising a housing having an inner chamber, the housing having a leading edge region in fluid communication with the inner chamber, the leading edge region being arranged to engage an access region between an article and a support surface beneath the article, an elongate tubular member having a first open end region and a second closed end region, the first open end region being directly or indirectly in fluid tight relation with the leading edge region, the elongate tubular member having a first surface in fluid communication with the inner chamber and an opposite second surface, the housing being arranged to provide a retracted position in which the elongate tubular member is held relative to the leading edge region and responsive to an operative pressure within the inner chamber to unfurl beyond the leading edge region to cause the elongate tubular member to migrate along the access region with the second surface in contact with the article and the support surface and with minimal relative motion between the contacting surfaces of the elongate tubular member, the article and the support surface and toward a deployed position in which the tubular member extends a distance exceeding a lateral dimension of the article with opposed ends of the tubular member being available to be employed for lifting the article from the support surface. | 02-19-2009 |
20100082182 | Powered wheelchair - A powered wheel chair device comprises a motorized undercarriage and a support seat for supporting a wheelchair occupant. At least one support arm is located adjacent the seat. A controller is mounted on the arm, the controller including a joystick unit within reach of the occupant. The joystick is in communication with the motorized undercarriage for driving the undercarriage. The joystick includes an upstanding post with a collar, the collar having a periphery with a number of abutment regions located therealong. A number of actuators are provided, each movable from a storage position distal to the corresponding abutment region and a deployed position adjacent the corresponding abutment region. Each actuator is responsive to an obstacle detecting sensor near a corresponding peripheral region of the undercarriage. | 04-01-2010 |
20120181495 | LIFTING ASSIST DEVICE - Disclosed herein is a device for lifting an article comprising a housing having an inner chamber, the housing having a leading edge region in fluid communication with the inner chamber, the leading edge region being arranged to engage an access region between an article and a support surface beneath the article, an elongate tubular member having a first open end region and a second closed end region, the first open end region being directly or indirectly in fluid tight relation with the leading edge region, the elongate tubular member having a first surface in fluid communication with the inner chamber and an opposite second surface, the housing being arranged to provide a retracted position in which the elongate tubular member is held relative to the leading edge region and responsive to an operative pressure within the inner chamber to unfurl beyond the leading edge region to cause the elongate tubular member to migrate along the access region with the second surface in contact with the article and the support surface and with minimal relative motion between the contacting surfaces of the elongate tubular member, the article and the support surface and toward a deployed position in which the tubular member extends a distance exceeding a lateral dimension of the article with opposed ends of the tubular member being available to be employed for lifting the article from the support surface. | 07-19-2012 |
