The present disclosure provides a method and system by which a precise amount of a viscous fluid sealing compound can be dispensed at required locations through computer vision-based observation of the fluid deposited, its rate and amount of deposition and location; and that the dispensed fluid may be accurately shaped through robotic or other special purpose mechanism motion. The invention enables instant quality inspection of the dispensing process in terms of the locations, amounts and shapes of newly created seals.

Portable hybrid system for application of any material of drywall compound material, paint material, and texture material by the hybrid system via any of a plurality of material expulsion outlet ports, comprising: a pressurizable hollow tank for carrying material, at least one air compressor for pressurizing the material from the tank, an optionally attachable paint roller subsystem, an optionally attachable paint sprayer subsystem, an optionally attachable drywall compound applicator subsystem, an optionally attachable texture applicator subsystem, and an optionally attachable edge-cutting porous paint pad subsystem, enabling a plurality of workers to apply a given material from a single tank of the material.

According to some embodiments, a system and method for dispensing a floor coating in a specified ratio of multiple components is disclosed. The system and method may set and maintain a desired ratio of the multiple components by controlling, with a controller, a drive rate of respective pumps configured for propelling the components from a reservoir to a mixer or a dispenser. The controller may be responsive to at least one of a measured actual drive rate, an environmental condition, an actual usage of each component, and an operational parameter of the system, for adjusting a drive rate of the respective pumps to compensate for discrepancies that may affect the ratio of the multiple components.

A handheld applicator for delivery of post-treatment coating following application of a conversion coating includes a first vessel extending longitudinally and containing SOCOSURF PACS? solution, a second vessel extending longitudinally and containing hydrogen peroxide, a pH indicator contained in one of the first or second vessels, a mixing region configured to combine the SOCOSURF PACS? solution, hydrogen peroxide, and pH indicator.

The disclosure concerns a mixing valve for mixing two coating agent components (e.g. master batch and hardener) to form a multi-component mixture, with two coating agent inlets for supplying the two coating agent components and with two coating agent valves for controlling the coating agent flow through the two coating agent inlets, as well as with a coating agent outlet for discharging the multi-component mixture in a specific outflow direction. The disclosure provides that at least one of the coating agent valves is formed as a rotary slide valve having two plane-parallel valve discs which are rotatable relative to each other about an axis of rotation.

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.

A multi-material deposition arrangement for deposition extrusion includes at least one first deposition-head having at least one inlet; wherein at least one inlet is configured to receive a plurality of deposition materials in at least one of a selective manner or simultaneous manner, wherein when at least one inlet receives the plurality of deposition materials in selective manner at least one first deposition-head is operable to perform layer deposition of single layer or stacked layers of individual deposition material, and when at least one inlet receives the plurality of deposition materials in simultaneous manner the at least one first deposition-head is operable to perform layer deposition of single layer or stacked layers of mixed deposition material of plurality of deposition materials.

A dispensing system for dispensing a hot melt adhesive foam onto a substrate is described. The dispensing system comprises a pump having a first input to receive a hot melt adhesive and a second input to receive a gas, where the pump mixes the hot melt adhesive and the gas to produce a solution. The dispensing system also includes a temperature sensor to detect a temperature of the solution, a dispenser to receive the solution from the pump and dispense the solution, and a controller. The controller instructs the pump to operate at a first speed, receives the temperature of the solution, and instructs the pump to operate at a second speed that is different than the first speed in response to the signal.

Described herein is an apparatus for dynamic metering of sealant volumes, and also described herein is a corresponding method.

The apparatus of the invention includes two containers for sealant components; a first drive, which is connected to two devices, each of which is able to convey one of the sealant components from its container; a drive controller; a mixing unit for mixing the sealant components conveyed from the containers, having an opening for applying the sealant to a component; and also, additionally, a compensating container with a compensating volume; and a second drive, which is connected to a piston which reaches into the compensating volume of the compensating container.

The compensating container in this arrangement is connected to the mixing unit. The first drive and the second drive can be dynamically controlled jointly by the drive controller.

Exemplary coating devices and exemplary coating methods for coating components with a coating agent, e.g., for painting motor vehicle body components with a paint, are disclosed. An exemplary coating device comprises an application device that applies the coating agent. The application device may include a paint head that discharges the coating agent out of at least one coating agent nozzle.
