An erosion test apparatus includes a combustor configured to obtain a combustion gas by mixing and combusting compressed air and a fuel, and an erodent supply unit configured to supply an erodent to the combustion gas. The erosion test apparatus further includes an accommodation support unit configured to accommodate and support a test piece having a front surface coated through thermal barrier coating, and an accelerator configured to accelerate the combustion gas including the erodent to collide with the test piece.

A device to standardize laboratory air-particle abrasion testing includes a specimen section and a handpiece section, each located on ends of a platform. The specimen section includes a specimen metal table, a specimen metal plate, a metal clamp, a clamp locknut, and a horizontal arm that connects the specimen metal table to the specimen metal plate. The clamp locknut tightens the metal clamp around a specimen, and the metal clamp holds the specimen on the specimen metal table. The handpiece section includes a vertical arm and an abrasion handpiece. The abrasion handpiece extends through an aperture in the vertical arm and an abrasion handpiece holding screw surrounds a circumference of the abrasion handpiece so that the abrasion handpiece is fixed longitudinally when extending through the aperture in the vertical arm.

A computer-based ordering system for ordering goods and services includes a plurality of self-service client terminals and a server. Each self-service client terminal runs a self-order application including a set of interactive menu screens having buttons that allow the customer to select and customize products for the order. An administration tool application communicates with the server to administer the self-service client terminals. The administration tool application including a menu editor that enables the administrator to create and edit the interactive menu screens provided by the self-order application at the self-service client terminals. The menu editor accesses a library of menu templates containing predefined groupings of buttons, and uses the menu templates, as directed by the administrator, during creation and editing of the interactive menu screens.

A device and a method for debris flow abrasion testing and a method for abrasion quantity evaluation of debris flow prevention and control engineering are provided. The device for debris flow abrasion testing of the present disclosure is an improvement of its own patented product, and a testing block box assembly includes a testing block box, an outer side of the box is apertured and centered with an annular member. The annular member is screwed with a fixing member and a placeholder member. The fixing member fixes the testing block and the placeholder member blocks a sampling operation hole to ensure that a bottom of the box is leveled. The testing block box assembly includes a stop member or a disassembling member.

Apparatuses, systems, and methods are described herein for high velocity erosion. The apparatus comprises a container, a propellant stored in the container, wherein the propellant is stored under pressure in the container, an applicator, the applicator being in fluid communication with the container, the applicator comprising a heater, and a controller for controlling the heater and the flow of propellant from the applicator, wherein the applicator is structured to discharge the propellant at a high velocity.
