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 sealing an open channel and a earner that provides a mechanism for applying an adhesive and/or a two-part adhesive caster are disclosed.

A two component adhesive system pumps a first adhesive component and a second adhesive component into a replaceable mixing unit that can be periodically replaced when the adhesive has cured in the mixing unit. The adhesive system has a robotic arm coupled to a gripper unit which has an open position and a closed position. In the open position, the gripper unit releases the mixing unit allowing the mixing unit to be replaced. The robotic arm moves the gripper unit to install a replacement mixing unit. The gripper unit can be moved to the closed position and the adhesive can be pumped through the mixing unit.

A device (1) for introducing a plugging compound (20) into a borehole (21), the device having a sleeve (2) with a cavity (3) for receiving the plugging compound (20). On one side, the sleeve (2) has a discharge opening (5), corresponding to the cavity (3), for discharging the plugging compound (20), and a support section (7), projecting laterally from the sleeve, for providing a support option for the sleeve (2) during introduction of the plugging compound (20). On the opposite side of the sleeve (2), an upper opening (4) is provided, through which a piston (16) together with a feed plate (18) protrudes into the cavity (3). The piston (16) is movable relative to the sleeve (2) in such a way that the feed plate (18) can be displaced in the cavity (3), for example to allow the plugging compound (20) to be received and dispensed.

An assembly can be used for packaging chemical compounds. The assembly includes a foil pack for storage of a one-component or multicomponent compound, and a dispensing device for the foil pack. The foil pack has at least one elongated foil bag designed to be non-rigid, and one rigid head part having at least one fastening portion for one end of the foil bag and an outlet opening for discharge of the compound, where the dispensing device has at least one receptacle for pushing in the at least one film bag. The at least one elongated foil bag has, in a filled condition, the form of a truncated cone, the diameter of which narrows in the direction of a longitudinal axis, starting from the respective fastening portion.

A glue gun dispensing nozzle indicator changes color when a heater element exceeds a transition temperature. In one embodiment, the temperature indicator changes from a blue color to a red color to indicate that the temperature is sufficient so that the glue gun may dispense molten glue. Temperature dependent color pigments are applied as coatings to the indicator.

The invention relates to an application nozzle (5.) for plastic sealants in a pasty form which can be easily and uniformly guided. The functional principle of the invention relates to a molding region (14.) made of an elastic structured rubber (8.) which is positioned by a guiding system, flexibly adapts to the adhesive surfaces, and has a pressure point-developing effect as a result of the molding region (14.) being sealed laterally or to the front (in the guide direction). By means of the pressure resistance, which changes noticeably to the user, in the counter-pressure of the hand lever during a manual application process using a conventional application pistol, the actuation of the hand lever becomes a simple control variable, from which a flawless visible surface results in a work process which is easy to control. The sealant material can be applied horizontally and vertically, as well as in an overhead position, in an approximately loss-free manner. The guiding system of the application nozzle (5.) consists of two contact bodies ((16.) and (21.)). By virtue of the dual function of the second contact body (21.), a central sealant abutment can be produced.

The embodiments of the invention as described herein relate to a tool or device for sealing exterior duct joints. The device is designed and configured to drive a semi-solid mastic or cement-like material through a hose and a custom designed applicator wand. The various embodiments of the invention include cordless, lightweight and portable versions. This tool is designed to assist in the sealing of ductwork. An extension on the end of the wand enables a user to reach several areas that are either difficult to access, or awkward to seal using traditional techniques. Various embodiments of the spreader head have been designed to perform better for different parts of the duct system. The user only needs a ladder to seal the top of the supply trunk duct, the remainder of the ductwork can be sealed standing on the floor.

A variety of dispensing manifolds which are removable connectable to a single deformable container having a single exit portion are disclosed. The dispensing manifolds of the present disclosure provide a single deformable container having a single exit with one or more outlets from which a fluid can be controllably dispensed. The present disclosure also provides a single force generation mechanism, a deformable container holding a fluid or substance, and dispensing mechanisms all on one machine, i.e., a carrier; a system that may also include a pressurized air source that assists a flow of a fluid; and a system that allows for a continuous flow a substance. The systems of the present disclosure provide a deformable container and a method of dispensing wherein, during dispensing, an actuation member is continuously free of contact with the fluid or substance within the container and the actuation member only contacts the exterior surface of the deformable container.

A non-stick, durable, and long-serving coating in an inner surface of a tube that transports adhesive, a material of the coating includes polysiloxane. The polysiloxane includes a first monomer unit and a second monomer unit. The first monomer unit is at least one group selected from the group consisting of OSi(R.sub.1)(R.sub.2)(R.sub.3), Si(R.sub.1)(R.sub.2)(O).sub.2, and Si(R.sub.1)(O).sub.3, the R.sub.1, R.sub.2 and R.sub.3 being independently selected from the group consisting of substituted alkyl and unsubstituted alkyl. The second monomer unit includes Si(O).sub.4. An injection needle and a method for manufacturing the coating on an injection needle is also provided.
