  • Patent number: 11426001
    Abstract: This invention will provide a lightweight, portable device which will be adjustable and can be used outdoors in all types of environments. The device can be configured into multiple shapes for extra utility while the device is used. For instance, the user can lie flat on the device as well as form the device into a chair. Other features that may be incorporated into the device include a storage compartment, a cell phone compartment, and an air conditioner and the ability for more than one person to use the device. In some of the embodiments the device can be used by two people.

  • Publication number: 20070107649
    Abstract: The present embodiments of the invention generally relate to a watercraft recovery device and method. The watercraft recovery method provides for operatively releasing an anchor from a watercraft, starting the watercraft, and steering the watercraft. The watercraft recovery device allows fisherman or other users to wade away from the boat and to recover the watercraft without re-navigating the water to return to the watercraft. This will help to ensure that fisherman or other users can quickly recover their boat in the case of an unexpected storm that makes the water conditions unsafe.

  • Publication number: 20070032909
    Abstract: A system and method is provided to control and operate a compressor to have two or more discrete output capacities in response to an outdoor temperature measurement. During operation of the compressor in an air conditioning or cooling mode, the compressor has a first output capacity in response to the outdoor temperature being greater than a first temperature setpoint and the compressor has a second output capacity in response to the outdoor temperature being less than a second temperature setpoint.

  • Publication number: 20050066673
    Abstract: A pressure equalization system is provided for starting a compressor while maintaining the condenser at a high pressure and includes a valve and a bleed port. The compressor has a compressor inlet for receiving a fluid at a first pressure and a compressor outlet for discharging the fluid at a second pressure, and is operable to compress the fluid from the first pressure to the second pressure. The valve is proximate to and in fluid communication with the compressor outlet and is movable to an open position when the compressor is operating to permit the fluid at the second pressure to flow through the valve and is movable to a closed position when the compressor stops operating to prevent backflow of the fluid at the second pressure through the valve toward the compressor inlet. The bleed port is upstream of the valve and in fluid communication with the compressor inlet to equalize the pressure of the fluid contained in the compressor when the compressor stops operating.

  • Publication number: 20050040727
    Abstract: A method of assembling and manufacturing a laminated rotor is provided which uses laminations having a thin bridge thickness. Different techniques are provided for preventing the molten material used in the casting or injection molding operation from leaking or seeping between the laminations during casting. In one technique, the laminations are stacked and oriented in the conventional way, and then both axial and radial pressures are applied to the stacked laminations to hold the laminations in position for the casting process. In another technique, the laminations are formed or extruded with a lip or collar portion that fit in a countersunk portion of an adjacent lamination and forms a wall or barrier between the laminations to prevent the leakage of the molten material during the casting or injection molding operation.

  • Publication number: 20050000083
    Abstract: A method of attaching a rotor to a shaft is provided to obtain increased motor performance. The increased motor performance is obtained as a result of a high impedance gap that is formed between the rotor bars and the rotor core during the heat shrinking operation to attach the rotor to a shaft. In the heat shrinking operation, the rotor is heated to between 600-800° F. At this temperature the aluminum in the rotor bars expands faster than the steel in the rotor core and causes a deforming or yielding of one or both of the materials. As a result of this deformation of the material, the cooling of the rotor results in the formation of a gap between the rotor bars and the rotor core that operates as a high impedance barrier between the rotor bars and rotor core.
