The disclosure relates to a supply system for supplying multiple consumers with a substance to be applied, preferably paint, for application to motor vehicle bodies and/or add-on parts thereof. The supply system comprises a feed line, a return line, a first consumer device which comprises a first consumer, the first consumer being connected to the feed line and the return line and preferably forming a first consumer of the feed line in the flow direction of the substance to be applied, and a further consumer device which comprises a further consumer, the further consumer being connected to the feed line and the return line and preferably forming a last consumer of the feed line in the flow direction of the substance to be applied and/or being arranged after the first consumer in the flow direction of the substance to be applied. The supply system is distinguished in particular in that the feed line is connected to the return line via a connecting line. The disclosure relates further to an associated coating installation and to an associated supply method.

A method for maintenance of railroad wood ties is presented herein. The wood filler composition used in the method is applicable for filling holes or gaps in wood to stabilize wood structures. The composition comprises at least unintahite, also known as asphaltum or Gilsonite, and sand. The composition may further comprise a water repellant and a wood preservative. The composition is non-carcinogenic. The method comprises filling a hole with the dry composition described herein. The wood member may be a railroad tie and using an appropriate filling device, at least two holes, or at least four holes may be filled at one time.

Devices and methods for preparing a slurry for coating onto a substrate. The devices and methods of the present disclosure relate to providing a slurry in a closed volume with at least one passage. The slurry includes a solvent, a powder, and a binder. The slurry can also include a dispersion agent. The slurry is forced repeatedly under high pressure through the at least one passage in a first flow direction and then back through the at least one passage in a second flow direction, opposite the first flow direction. The forcing homogenously disperses the powder and the binder within the solvent. Both sides of the substrate are then coated simultaneously with the slurry extruded from the closed volume after the forcing. Curing of the coated slurry includes freeze drying to preserve the porosity of the slurry on the substrate.

A manifold that allows for increased flow performance, at a reduced pressure, and a flow path that is easily maintained, and fluid dispensing systems that allow for the precise, controlled spacing of beads of multiple component adhesives, and other liquids, and allow for multiple beads to be dispensed onto a substrate simultaneously are disclosed. A control portion for a manifold that solves the disadvantages relating to scaling an open channel and a carrier that provides a mechanism for applying an adhesive and/or a two-part adhesive easier are disclosed.

A delivery unit for dispensing adhesive having a housing, a melting apparatus arranged within the housing for melting the adhesive, a distributing device for dispensing molten adhesive in at least one line connectable to the distributing device, and a pump for conveying the molten adhesive through the distributing device, wherein the housing has a plurality of outer side faces, two of the outer side faces are of a flat configuration and arranged perpendicular to a support plane of the delivery unit on a base and substantially at a right angle to each other, and wherein the distributing device, in a region in which the line is connectable to a connector of the distributing device, has a boundary surface of a flat configuration. The two outer side faces are arranged at a distance apart with the boundary surface therebetween forming an obtuse angle with each of the two outer side faces.

A method of forming additive energy directors according to various exemplary embodiments can include dispensing a molten material onto a substrate at a predetermined location. The method also includes solidifying the molten material to form at least one additive energy director onto the substrate.

The present disclosure provides a coating device including a first storage tank for storing a material to be coated, a needle cannula to which the first storage tank is connected by means of a corresponding first line, a gas output device for outputting a first pressurized gas from a gas source, including a first gas output line extending into the first storage tank, wherein the gas output device is capable of outputting the first pressurized gas to the first storage tank through the first gas output line such that the material to be coated stored in the first storage tank is discharged under a gas pressure and enters the needle cannula through the first line.

A system for field internally coating a pipe joint comprising a polymer application unit, which has a first cart configured to selectively advance inside a pipe; a first and a second tank configured to contain a first and a second polymer component respectively; a mixer to mix the first and the second component; a first and a second pump to feed the first and the second component respectively from the first and the second tank to the mixer; an applicator to apply the polymer to the pipe; and a conduit comprising a free end configured to be placed near the applicator to feed the polymer from the mixer to the applicator.
