A manufacturing method of a sound insulating layer by application of raw materials for urethane resin, by applying row materials for urethane resin in their liquid states along a surface of a porous layer of a soundproof body to manufacture as the sound insulating layer.

A spray fluid operation system for an agricultural sprayer and method for operating same is disclosed. The method comprising: providing a spray fluid in a reservoir; and conveying at least one of the spray fluid and an additional fluid into a fluid flow system by a pump and control system (PCS). The fluid flow system comprising a dispensing device configured to dispense a first pumped fluid from the PCS to a field, and a backflow system configured to pipe second pumped fluid from the PCS back to the reservoir. The method further comprises: determining a fluid level in the reservoir; receiving the fluid level in a control device; generating the second pumped fluid by the PCS; and controlling allocation of the second pumped fluid according to an allocation ratio to: a first return device and a second return device configured to return the second pumped fluid to the reservoir.

A process for flushing a dispenser that dispenses liquids, especially perfumes, containing microcapsules. The dispenser has a first reservoir for a first composition containing microcapsules and a second reservoir for a second composition containing a volatile solvent. The dispenser also has a swirl chamber and a premix chamber. The process simultaneously pumps the first and second compositions into the premix chamber and then into the swirl chamber. The pumping of the first composition is halted while the pumping of the second composition continues, and this provides an extra volume of the volatile solvent, which flushes the dispenser to prevent clogging by the microcapsules.

An airless pump container equipped with an impregnated member and an absorbing member includes: a container main body (10); a pushing plate (20); an impregnated member (30) installed inside of the container main body (10); a shielding member (40); a pump holder (60) coupled to the upper portion of the shielding member (40); an airless pump (50) installed on the inside of the shielding member (40) and the pump holder (60); an absorbing member holder (70) coupled to the upper end of the airless pump (50); an absorbing member (90); and a moving member (100) for fixing the absorbing member (90). The impregnated member is impregnated with content in a gel-state.

The present invention relates to devices and methods for coating surfaces including surfaces of medical devices, in particular the coating of microprojections on microprojection arrays. The present invention also relates to print head devices and their manufacture and to methods of using the print head devices for manufacturing articles such as microprojection arrays as well as to coating the surfaces of microprojection arrays. The present invention also relates to high throughput printing devices that utilize the print heads of the present invention.

In-wall dispensing modules, such as room freshener modules, can reside in a housing with a cover that can be opened to access an interior space of the module to, inter alia, replace used containers. The housings are configured to reside inside a wall of a room. The front cover can be a planar cover that is flush, slightly recessed or slightly protrudes from the wall. The housings can be a “custom” housing size and/or may be configured to occupy a single gang box or a compartment of a multi-gang junction box. The modules can include an actuator that can cause a canister to emit scented fluid at desired intervals and/or on-demand. The modules can have a User Interface (UI) wireless and/or wired connection to a whole-house “smart” system.

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.
