20110311378 | DIAPHRAGM INSTALLATION TOOL - An air-driven dual diaphragm pump comprises a pump body with a first air passage leading to a first air cavity with a first diaphragm, a second air passage leading to a second air cavity with a second diaphragm, and a reciprocating shaft which connects the first and second diaphragms. A diaphragm installation tool for the dual diaphragm pump comprises a plate which fits atop the pump body. A groove in a surface of the plate opposite from and nonadjacent to the pump body extends from the location of the first air passage to the location of the second air passage. A hole located within the groove at the location of either the first air passage or the second air passage extends through the plate. Pressurized air entering the pump body is redirected by the groove and the hole to always enter the first air passage, rather than the second, thereby slowly filling the first air cavity and positioning the second diaphragm for installation. | 12-22-2011 |

A clamp allows the user to fasten the unit to an edge of the waste bag with the bag walls between the magnet and the armature. When the bag contents reach the magnet, fluid force of the bag contents separates the magnet and the armature, causing the switch element to close and conduct power from a power supply to a signal element. The arm may be flexible. The switch element preferably comprises a reed switch controlling an electronic power switch. | 06-16-2011 |

In some embodiments a lumbar wear-pad may be field replaceable on a fall-protection safety harness. An exemplary embodiment may have three prominences, a smaller center prominence located near a wearer's lumbar vertebrae and two side prominences located near a wearer's hip bones. In some embodiments, the lumbar wear-pad may be flexible so as to anatomically conform to a wearer's body. Exemplary lumbar wear-pads may provide protection for both a wearer and the wearer's harness during sliding or leaning engagements with vertical surfaces. | 02-05-2015 |

20080269676 | High flow rate infusion with extraction assist - An infusion unit includes a heating unit with opposed heating plates. A heat exchanger has a fluid flow path receivable between the heating plates to which heat is conducted by contact with the heating plates. Infusate flowing under pressure through the fluid flow path is heated by conduction from the heating plates through the fluid container. When the flow of infusate is stopped or interrupted, infusate trapped in the heat exchanger is displaced to a reservoir in the heat exchanger. Displacement of the trapped infusate reduces friction between the fluid container and the heating plates, which assists in extraction of the heat exchanger from the heating unit. | 10-30-2008 |
