  • Publication number: 20250136209
    Abstract: A base trailer and trailer kit for forming a base trailer is disclosed. The base trailer and trailer kit comprises a plurality of modular rails and a plurality of brackets. To form a trailer frame without welding or drilling, the plurality of modular rails are interconnected by the plurality of brackets. Depending on the desired trailer configuration, the type of load carried, or the task to be performed, the base trailer and trailer kit accommodate an accessory mounting system, at least one accessory bracket, and/or one or more accessories. The base trailer and trailer kit allow for modification and customization of a single trailer frame into one or more trailer configurations.

  • Publication number: 20250105684
    Abstract: An integrated compressor comprises an electric motor that is prone to high temperatures. In a first cooling feature, axial and/or radial cooling channels are provided through the stator of the motor to supply coolant to portions of the stator that are prone to high temperatures. In a second cooling feature, jets are used to spray coolant towards the end-windings of the motor, to thereby cool the end-windings.

  • Publication number: 20250105698
    Abstract: Traditionally, integrated motor compressors utilize a radial penetrator that is connected to the motor stator via terminals and wires. This radial connection requires the motor stator to be installed within the compressor housing prior to the connection. In addition, the wires are subject to failure from rapid gas decompression. Accordingly, an axial penetrator is disclosed to provide a conductive path, through the housing, parallel to the longitudinal axis of an integrated motor machine (e.g., integrated motor compressor). This enables the connection to be performed prior to installation of the motor stator within the housing. This also enables the conductive path between the motor windings and axial penetrator to be formed, as a single integrated path, using the same conductive and insulative materials. In turn, this ensures that the entire conductive path behaves the same during decompression, reduces costs, simplifies the installation process, and increases the robustness of the connection.

  • Publication number: 20250079914
    Abstract: An integrated compressor comprises an electric motor that is prone to windage losses, radial loads, and recirculation flows. According to a first feature, partial grooves or riblets may be formed on the surface of a motor stator that defines the radially outward boundary of the air gap between the motor stator and the motor rotor. These partial grooves or riblets may maintain low to moderate windage losses, while reducing radial loads in the motor. According to a second feature, a support structure may be designed with a nose portion that is configured to disrupt or otherwise reduce recirculation flows within the end-winding cavity housing the end-winding of the motor. According to a third feature, the spiral orientation of the top coil of the end-winding may be aligned with the rotation direction of the motor rotor to reduce recirculation flows within the end-winding cavity.

    Abstract: An employee location noticeboard is in the form of a dry-erase board, with a list of prepared options and checkboxes providing specific details about the employee's current location and estimated time of return. The noticeboard also provides some options that are not intended to be actually used, but instead may provide harmless amusement for the reader. A method of producing noticeboard content provides for determining legitimate reasons for an employee to be away from his or her desk, determining not legitimate but humorous reasons for the employee to be away, and printing the list on the noticeboard. The noticeboard features suction cups for easy mounting on an office door.
