A system and method for the application of friction-modifying coatings to roadways, walkways, pathways and other areas subject to vehicular, human or animal traffic, the system and method comprising the controlled, simultaneous application of binder and filler to a surface of a substrate, using a mobile device which passes over the substrate as the binder and filler are being applied. The system includes a mobile platform configured for being coupled to a vehicle. A binder applicator is mounted on the mobile platform and includes an array of spray nozzles coupled to a resin container. An air knife is mounted on the mobile platform and coupled to an air compressor for generating an air curtain. An aggregate dispenser bar including at least one aggregate dispenser is coupled to an aggregate bin and mounted on the mobile platform for dispensing aggregate.

Systems and methods for applying roadway surface treatments. The system has an aggregate application assembly and a resin application assembly that are mounted or otherwise secured to a truck or other vehicle. The resin application assembly is spaced from the aggregate application assembly in the direction of travel of the vehicle. As the vehicle moves along a roadway surface, the resin and aggregate can be continuously applied such that the aggregate is provided to portions of the roadway surface that have been covered with resin.

A dispenser for discharging a mixture of gas and paste material includes: a nozzle part (2) provided in a tip end part of a body (11) and having a tip end opening; a flow path (4) for the mixture extending from an introduction part (5) for the mixture to the tip end opening through a hollow space of the nozzle part; a needle part (3) movable in the flow path of the nozzle part to open and close the flow path; a driving part (7, 8, and 9) that drives the needle part; and a stopper part (10, 14, and 16) that limits an operation range of the needle part. The nozzle part has a tapered section in which an inside diameter of the flow path of the nozzle part relative to an operation range of a tip end of the needle part decreases toward the tip end opening.

A fragrance dispensing system includes a first and a second container each having a main tube for the expulsion of a fragrance contained therein, and a dispensing device that provides a dispensing path towards an outlet section and that includes a mixing chamber and a first and second auxiliary tubes connected at one end to the mixing chamber. A containing case forms a seat containing the first and second containers, and a cap is configured to be applied on the containing case and houses the mixing chamber, an outlet section for the mixed fragrances and, at least partly, and the first and second auxiliary tubes, each of which has a free end separably connected to one of the main tubes when the cap is engaged to the case.

An absorbent body in which a larger amount of a granular absorbent substance penetrates into the inside of a fiber sheet is produced. A fiber sheet having napped one main surface is supplied to a conveying device and conveyed while the other main surface of the fiber sheet is being sucked through a conveyance surface. A granular absorbent substance is sprayed onto the napped one main surface of the fiber sheet to cause the substance to penetrate into the inside of the fiber sheet in a suction section. A pressure difference increasing device is provided that faces the one main surface of the fiber sheet sprayed with the absorbent substance and being conveyed in the suction section, and that suppresses air from flowing through the fiber sheet inward from the conveyance surface to increase the pressure difference between the conveyance surface side and the opposite side of the fiber sheet.

An electrical connector system for use with independently heated hoses includes a first electrical connector, a second electrical connector, a third electrical connector, and a fourth electrical connector. The first electrical connector includes a first key that mates with a second key of the second electrical connector. The third electrical connector includes a third key that mates with a fourth key of the fourth electrical connector. The first and second keys differ from the third and fourth keys, ensuring the electrical connectors are correctly connected.

A coating method of supplying a treatment solution to a substrate and coating the substrate with the treatment solution by a spin coating method, includes mixing a solvent for the treatment solution lower in surface tension than the treatment solution into the treatment solution concurrently with a start of supply of the treatment solution or later than the start of the supply of the treatment solution, and then supplying the treatment solution to the substrate.

The present invention generally relates to methods of printing articles using three-dimensional printing and other printing techniques, and to articles formed from such techniques, including the printing of articles of footwear containing particles. Certain embodiments are generally directed to composites comprising particles (e.g., reinforcing particles), for example, rubber particles. The particles may be used, for example, to increase slip or abrasion resistance. The composites may also contain polyurethanes or other compounds, e.g., to facilitate fabrication, e.g., using three-dimensional printing and other printing techniques. Other embodiments are directed to methods of making or using such articles. For example, in some embodiments, a composite may be prepared by mixing particles (e.g., reinforcing particles) with at least a first fluid and a second fluid within a nozzle, such as a microfluidic printing nozzle, which may be used to direct the resulting product onto a substrate.

A container unit including a plurality of container sub-portions (4) defining a plurality of chambers for containing a liquid substance, each container sub-portion including an outlet, the container unit further including a conduit device (12) serving to connect each of the outlets of the respective sub-portions to an outlet nozzle (8a). In one embodiment, a spray cycle is disclosed having first and second periods of flow allowance and purging respectively. In another embodiment, respective sub-portion (4) controllable liquid displacement devices for dispensing one or more of the liquid substances selected from one or more of the respective sub-portions (4) are disclosed.

A method for controlling a system pressure within a closed system includes sending a signal to a pressure control valve corresponding to a pressure set point and actuating the pressure control valve to vary a pilot pressure of a control fluid contained within a pressure control line that is fluidly connected to a pressure regulator. A diaphragm of the pressure regulator is disposed between the pressure control line and a system line and acts on a fluid with the system line to modify the system pressure.
