摘要:
A method for determining the durability of pellets (such as animal feed pellets) to ascertain at the beginning of a large scale production run whether the pellets are of acceptable quality: which includes: introducing a predetermined sized sample of pellets from the output of a pellet making machine into a screened-walled container, cooling the pellets followed by limited agiation for separating fine particles after which the container is tumbled to collect fine particles and finally comparing the thus collected fine particles against a predetermined standard.

The hardness of crushable materials is determined by an apparatus capable of applying a uniformly increasing compression force to the material undergoing test. This force is applied by a plunger exerting a downward pressure on the crushable material and by the weight of a receiving container suspended from the plunger. During the test, the weight exerted by the suspended container is continuously and uniformly increased by the flow of fluid from a reservoir tank into the receiving container. The flow of fluid is commenced by the opening of a normally closed solenoid valve in response to the closing of a relay switch. This switch is adapted to assume an open position when the weight of fluid in the receiving container becomes sufficient to cause the plunger to drop to a lower position upon crushing of the crushable material being tested. The opening of the relay switch, in turn, causes the solenoid valve to close upon crushing of the material being tested. The weight of the plunger and the suspended receiving container, together with the fluid in the container, provides a precise measure of the hardness of the crushable material.

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.
摘要:
A thermal erosion tester, comprising a rotating heated element, which is adapted to contact a sand specimen placed in the thermal erosion tester, a heating element to heat the rotating heated element, and a motor to drive rotation of the rotating heated element, wherein the rotating heated element is adapted to contact the sand specimen while the rotating heated element is rotating, causing erosion of the sand specimen, and a method of testing thermal erosion, and a method of testing erosion of a sand specimen when it is in contact with a heated element.
摘要:
A preform superabrasive cutter and a method of testing the preform superabrasive cutter are disclosed. The preform superabrasive cutter may comprise a superabrasive volume, metal carbide, and a slop. The superabrasive volume may have a top surface and superabrasive particles. The metal carbide may be attached to the superabrasive volume via an interface between the superabrasive volume and the metal carbide. The slope may be situated from the top surface of the superabrasive volume toward the metal carbide, wherein the slope is at an angle from about 5 to about 18 degrees relative to a longitudinal axis of the preform superabrasive cutter.

Methods and apparatuses are provided for testing and quantifying structural durability characteristics of bridging materials. Embodiments include sieving bridging materials to create uniform batches having particles within a predefined range. Embodiments further include selecting a batch and drying the batch, separating the dried batch into dry samples, and selecting a test sample having an initial mass. Embodiments include sealing the test sample, a volume of liquid, and a rod in a cylindrical testing cell and rotating the cylindrical testing cell containing the rod such that the rod rolls in relation to an inner wall of the cylindrical testing cell and applies force partially crushing the test sample. Embodiments further include sieving a resulting sample to create a durable sample having particles within the predefined range and drying the durable sample. Embodiments of methods further include measuring a mass of the dried durable sample to define a durable mass and comparing the durable mass to the initial mass.
