The closing structure (34, 52) is arranged and configured to be moved into a position, in which the outlet (26) is provided with a free passage, through which the liquid (36) leaving the outlet (26) is injected into the interior space (54) without colliding with the closing structure (34, 52).

A cleaning system is disclosed for cleaning concrete residue from a concrete mixer truck. The cleaning system may include a water delivery system having one or more conduits configured to deliver pressurized water to one or more spray headers positioned at various back-end portions of the truck. The cleaning system further includes one or more valves configured to control the flow of pressurized water through the one or more conduits to the one or more spray headers. In various embodiments, the one or more valves are manually operable to control the release of water to the spray headers. In other embodiments, the one or more valves are controlled by a computing device through an electrical coupling such as a communication bus. The cleaning system may be configured to clean different portions of the truck using different sets of spray headers at different times as part of a washing protocol.

A system for processing foodstuffs includes a container platform, a blade platform, and a locking mechanism. The container platform defines a container receptacle configured to receive a container including foodstuffs. The blade platform includes blades configured to rotate to process the foodstuffs. The locking mechanism is configured to couple the container platform to the blade platform to form a blending chamber including the blades and the container subsequent to determining that the container is received by the container receptacle and prior to rotation of the blades.

An automated beverage-making system includes one or more ingredient dispenser assemblies configured to store ingredients therein and disposed within a refrigerator/freezer system. Each of the ingredient dispenser assembles are in control communication with a communications hub and the communications hub is configured to receive instructions for actuating the one or more ingredient dispenser assemblies according to a recipe, wherein the ingredients are combined in a blender.

A full-electric drive cementing control system is disclosed. The system includes: a water supply system for supplying clear water; an ash supply system for supplying dry ash; a slurry mixing system for performing a slurry mixing operation to form slurry; a plunger pump for pumping the slurry to a cementing operation object; and a control assembly for controlling, in response to a received cementing operation instruction, connection of a pipeline between an outlet of the water supply system and an inlet of the slurry mixing system and a pipeline between an outlet of the ash supply system and the inlet of the slurry mixing system, controlling, according to a preset slurry mixing parameter, the slurry mixing system to mix the clear water and the dry ash to form the slurry required for a cementing operation, and controlling, according to a preset perfusion parameter, a driving motor to drive the plunger pump to work, the cementing operation instruction carrying the preset slurry mixing parameter and the preset perfusion parameter.

An apparatus includes a blender lid configured to cover an opening in a blender receptacle and a lid arm coupled to the blender lid and coupled rotationally about a first horizontal axis. The lid arm is configured to rotate about the first horizontal axis to selectively position the blender lid to cover and uncover the opening in the blender receptacle. The blender arm may rotate the blender lid about the first horizontal axis to cover the opening in the blender receptacle and apply a downward force on the blender lid to seal the opening of the blender receptacle with the blender lid. The blender arm may include a horizontal rod having a longitudinal axis that corresponds to the first horizontal axis and having a first end attached to the blender lid.

A preparation apparatus includes a first tank, a second tank, a preparation tank, and a computer having a hardware processor. The first tank contains a first liquid. The second tank contains a second liquid having a lower viscosity than the first liquid. The preparation tank stirs the first liquid supplied from the first tank and the second liquid supplied from the second tank to prepare a preparation liquid. The hardware processor measures a viscosity of the first liquid based on a supply time required to supply a specified amount of the first liquid at a constant pressure from the first tank to the preparation tank, and supplies an amount of the second liquid to the preparation tank based on the measured viscosity of the first liquid so as to cause the preparation liquid to have a target viscosity.

Apparatus for blending and applying plural substances including aggregate onto an environmental substrate is shown and described. The apparatus includes optionally a single power plant, plural pumps each fed by a respective hopper, and a blender blending pumped materials together. Dispensing ratios of the two pumps are mutually adjustable. An onboard air compressor delivers compressed air for atomizing blended materials as they are dispensed with the aggregate. Because materials may be curable or hardenable, flushing is enabled. The apparatus may be a free standing wheeled device.
