Abstract: The present disclosure relates to a liquid fuel self-sustaining combustion burner for flame synthesis, including a swirl-flow cylinder and a stable combustion cylinder. A swirl-flow plate is disposed at an open end of the swirl-flow cylinder and defines swirl-flow outlets. A tangential inlet tube is mounted on the swirl-flow cylinder and in fluid communication with the swirl-flow chamber. An open end of the swirl-flow cylinder extends into the stable combustion chamber. The fuel can be atomized by an atomizer and sprayed into the stable combustion chamber for combustion. Air introduced from the tangential inlet tube can flow into the swirl-flow chamber and advance spirally around the central stabilizing column to reach the swirl-flow plate. The airflow is partially injected into the stable combustion chamber through the swirl-flow outlets, and then continues to spirally advance. An atomizing nozzle of the atomizer is located inside the swirling airflow.

Abstract: A load card for testing different types of PCI slots is provided. The load card includes several gold fingers, and resistor selection circuits. Each gold finger corresponds to one PCI slot. Each resistor selection circuit includes a resistor to test at least one PCI slot working in one working voltage. When a PCI slot working at a working voltage is to be tested, the gold finger connects to the PCI slot, and the resistor selection circuit including the resistor to test the PCI slot working at the working voltage is enabled and others are disabled in response to an operation of the user.

Abstract: An exemplary load card includes an input unit, a processing unit, and a load unit. When inputting a predetermined voltage and a predetermined load power via the input unit, the processing unit receives and processes the predetermined voltage and the load power, and generates and outputs a corresponding binary control voltage. The load unit receives and converts the binary control voltage into an analog control voltage. Under the control of the analog control voltage, the load unit receives the predetermined voltage from a motherboard, and outputs the predetermined power to the motherboard.

Abstract: A mounting apparatus is used to position a fan in place and includes a base, a support arm extending up from the base, an angle adjusting member including a first rail rotatably coupled to the support arm, and a mounting member including a second rail slidably coupled to the first rail. The fan is fixed to an end of the second rail. The position of the fan is adjustable in respect of height and can also be adjusted to move closer to or away from a heat-generating component as required.

Abstract: A memory adapter receiving device includes a frame, a number of sliding blocks, and a number of connecting blocks. The frame includes a pair of sliding rails each slidably received in one sliding rail. Each connecting block is connected to one sliding block and is to connected to a memory adapter.
