Abstract: A laundry machine includes a cabinet, a lid, and a hinge. The cabinet is configured to receive clothing articles. The lid is secured to a top of the cabinet and is configured to transition between open and closed positions. The hinge rotatably secures the lid to the cabinet such the lid transitions between the open and closed positions via the hinge. The hinge comprises a post and an L-shaped bracket. The post protrudes upward from the top of the cabinet. The L-shaped bracket is disposed along a bottom of the lid and is configured to rotatably engage the post to transition the lid between the open and closed positions.

Abstract: A gas cylinder lifting and transport device, includes a base supported on a plurality of wheels; a source of power; a lifting device carried on the base; a clamping apparatus having actuators that receives power from the source of power, to clamp or unclamp a gas cylinder. The actuators can be pneumatic cylinders and the source of power can be an on-board battery-operated compressor supported from the base, the compressor being flow connected to the pneumatic cylinders. Alternatively, the source of power can be a battery and the actuators can be electrically actuated linear actuators. The lifting device can be a manually operated lever or a powered lifting device such as an electric linear actuator or a pressurized fluid.

Abstract: In one aspect of the invention, the system may include a liquid hydrogen storage tank that is placed on a mobile carriage. From the liquid hydrogen storage tank, a submerged pump feeds low-pressure liquid hydrogen to a second pump that is external to the tank. This second pump then increases the pressure of the liquid hydrogen and feeds the liquid hydrogen to a vaporizer system. The vaporizer system includes coolant, a coolant tank, a load bank, a third pump, and a diffusion bonded compact heat exchanger (DCHE) to transfer heat from the coolant to the liquid hydrogen. To further help heat the coolant, heat exchangers may be included to cool systems of the vehicle and recover waste engine heat. After the vaporizer converts the liquid hydrogen to its gaseous form, the gaseous hydrogen is discharged to an external vehicle or tank.

Abstract: A method and system for installing and maintaining submerged cryogenic pumps is disclosed. The submerged pump may be positioned within a product storage vessel. Alternatively the submerged pump may be positioned within a product storage vessel with a sump that is integral with and not removable from the vessel. The pump may used for the movement of products, such as cryogenic liquids, including but not limited to, nitrogen, argon, ethylene, natural gas, nitrous-oxide, carbon-monoxide, hydrogen, helium, and carbon-dioxide. Superior results are obtained with respect to access, maintenance and handling of the pump within a product storing vessel.
