Abstract: A conical burr coffee grinder can include a hopper that receives coffee beans, a grinding arrangement beneath the hopper, and a removable container beneath the grinding arrangement. The grinding arrangement can include an inner conical burr within an outer conical burr. At least one conical burr can rotate with respect to the other to grind the coffee beans into coffee grounds and dispense the coffee grounds into the container. The coffee beans and coffee grounds can follow a substantially vertical path from the hopper through the grinding arrangement and into the container, which can be multipurpose. A rotor gear can be coupled to the inner conical burr such that the rotor gear and inner conical burr rotate together as a combined unit. Additional components can include a rotational motor, a geartrain, a removable hopper lid, a grind adjustment assembly, a chute, an ionizer, a base, and a safety switch.

Abstract: A filtration system has a filter element with a filtration membrane, a feed inlet and a concentrate outlet on a first side of the membrane and a permeate outlet on a second side of the membrane. A feed line with a feed shutoff valve is in fluid communication with the feed inlet, and a concentrate return line with a concentrate shutoff valve is in fluid communication with the concentrate outlet. A feed pump is in fluid communication with the feed inlet via the feed line and the feed shutoff valve, and a backwash pump is in fluid communication with the permeate outlet. In a priming phase of a backwash operation, the feed shutoff valve and the concentrate shutoff valve are closed and the backwash supply is operable to deliver fluid to the filtration element and equalize pressure between the first side and the second side of the filtration membrane.

Abstract: A system or device may implement configuration and testing of network-based service platform resources using a service platform specific language. A configuration file may describe one or more resources of a network-based service platform to be configured, as well as one or more tests to be performed. The configuration file may be described in a service platform specific language for the network-based service platform. When received, the configuration file may be interpreted according to the service platform specific language to identify configuration information for the resources and execution instructions for performing the tests. Requests may be generated and sent to the network-based service platform to configure and provision the resources according to the identified information. Results of the tests may be obtained.
