A device for dispensing a spraying agent, e.g., a plant protection agent, includes a mixing unit for mixing two active agents to form a spraying agent, at least one of the active agents being suppliable to the mixing unit under pressure via a throttle unit, the throttle unit including a feed channel and a discharge channel that are fluidically connectable to each other via at least one throttle channel depending on a position of a throttle element of the throttle unit that is movably situated relative to the feed channel the discharge channel for setting a flow rate of the at least one active agent to be supplied to the mixing unit, the at least one throttle channel being situated at the throttle element and having a fixed channel cross section for keeping the through-flowing flow rate of the at least one active agent constant.

A method of generating a building assembly that includes spraying a coating material onto a plurality of pieces of substrate disposed on a first assembly face. The spraying includes spraying the coating material onto the plurality of pieces of substrate via a sprayer configured to apply the coating material to a target surface via a nozzle coupled with a mobile storage container storing the coating material, the coating material impregnating voids of the substrate. The method also includes allowing the coating material impregnating the voids to dry and harden and become rigid to generate the building assembly.

Provided is a liquid discharging head including: a membranous member including a discharging port through which a liquid is discharged; and a displacement member disposed at membranous member's one side at which the liquid to be discharged through the discharging port is provided and configured to displace a position of the membranous member to cause the liquid to be discharged through the discharging port.

A coating system for applying a coating to a substrate that can be part of a wall assembly. The system includes a positioning stage and an end effector coupled at a distal end of the positioning stage, the end effector configured to apply coating to a target surface. The system can further include a computing device executing a computational planner that: generates instructions for driving the end effector and positioning stage to perform at least one coating task that includes applying coating, via the coating the end effector, to one or more substrate pieces, the generating based at least in part on obtained target surface data; and drives the end effector and positioning stage to perform the at least one coating task.

A dispenser for dispensing a flowable product from a container has a pump module mounted on the container at an opening thereof. The pump module includes a pump body, which defines a pump chamber and a pump chamber inlet for product to flow from the container interior into the pump chamber. A pump actuator is operable in a pumping stroke relative to the pump body to vary the volume of the pump chamber and dispense the product. The pump includes a movable body portion which is operable in a displacement stroke into the container. The movable portion has a displacement body with a product-engaging face directed onto an interior product space of the container upstream of the pump chamber inlet, to assist priming. Below this a disrupter member, a grid of narrow bars, projects to penetrate the product.

An in-situ foam generation apparatus includes a dissolution chamber that houses a polymer stick cavity or canister, a mixing chamber that houses a static mixer, and a foaming chamber that houses a mechanical agitator in fluid communication with a compressed air inlet. The chambers are in fluid communication with one another by way of a respective chamber inlet and outlet, with the mixing chamber being located between the dissolution and foaming chambers. A pressure regulator can be used to control the incoming aqueous solution pressure to the dissolution chamber. A nozzle exhaust is in fluid communication with the outlet of the foaming chamber. One or more polymer sticks that include one or more cleaning agent can be loaded into the cavity or canister of the dissolution chamber. An end consistency of the polymer stick can be in a range of partially solidified to fully solidified.
