An adhesive applicator includes a receiver having a tubular body with a closed first end and an opposed second end, the tubular body having a deformable wall, an adhesive composition contained within the tubular body, and an applicator tip mounted on the tubular body and comprising a foam material having an applicator external of the applicator for applying the adhesive, the applicator being such that deformation of the tubular body causes the adhesive to be expressed through the applicator tip. The foam material is a reticulated foam felt and allows for relatively constant flow of the adhesive through the foam felt and to the applicator surface thereof over a wide range of viscosity conditions of the adhesive and pressure applied to the deformable body of the applicator.

A drywall finishing apparatus includes a water reservoir connected to a water distribution element. The water distribution element applies water to a finishing pad. The finishing pad is designed to allow water to flow through and reconstitute already applied drywall mud. The reconstituted drywall mud can then be smoothed out with the finishing pad. The finishing pad creates a hydroplaning effect to glide over the drywall mud.

Medical adhesive applicators are disclosed which allow medical adhesives to have long storage life and be easily dispensed in a controlled manner. In one embodiment, the applicator has a frangible glass vial with the medical adhesive. The frangible glass vial is held in a plastic enclosure with a dispensing tip. Attached to the plastic enclosure is a squeeze tube capable of imparting air pressure into the enclosure. To dispense medical adhesive quickly and with precision, one simply breaks the frangible glass vial and pushes on the squeeze tube. In another embodiment, the applicator has a proximal chamber containing medical adhesive, a distal chamber for dispensing medical adhesive and one or more rupturable membranes between them. To achieve long shelf life, the applicator chambers and membrane(s) are formed from fluorinated plastic. To dispense medical adhesive, one ruptures the membrane(s) and pushes on the sides of the proximal chamber.

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.

Methods and apparatuses are disclosed relating to the delivery of primer compounds in liquid form to substrates from a hand-held device. Apparatuses are disclosed that, in a single barrel device, store primer components, mix primer components to achieve an activated primer, and deliver the activated primer to a substrate surface.

A coating tool includes a holder having an applicator head extending between a first end and a second end. The applicator head is hollow along at least part of its length to define an internal cavity delimited by an inner wall. The applicator head has an outer rim at the first end. A foam applicator has a collar portion attached to the outer rim of the applicator head, and a body portion extending from the collar portion inwardly into the applicator head and disposed within the internal cavity to be displaceable relative to the inner wall. The foam applicator has an applicator opening extending through the collar portion and at least part of the body portion. The foam applicator is made of a foam material which, upon receiving a coating, expands inwardly to reduce a volume of the applicator opening. A coating method is also disclosed.

An adhesive dispenser is includes a plurality of adhesive dispensing parts, each including an adhesive dispensing tube, an adhesive extrusion assembly, and a driving component. The adhesive dispensing tube is configured to carry an adhesive therein. The adhesive extrusion assembly is connected with the adhesive dispensing tube, and is configured to apply a pressure to the adhesive in the adhesive dispensing tube such that the adhesive is dispensed from the adhesive dispensing tube. The driving component is configured to drive adhesive extrusion assemblies of the plurality of adhesive dispensing parts to apply the pressure to the adhesive.

A mud pumping apparatus that can be removably coupled to a container the mud was originally provided in when first obtained by the user. The mud may be mastic, mortar, grout, joint compound, spackle, or the like. The apparatus may be sized to be used with various standard sized containers, and adjustably powered and controllable to be used with different types, consistencies, and viscosities of spreadable material.

The invention relates to a plastering machine (10) for applying a surface coating layer to a building surface (1), such as to a building wall (1), comprising a coating material supply (20) connected to a mouthpiece (30) via a conduit, said mouthpiece (30) having a top portion (T) and a bottom portion (B) and including a rear wall (31), a first side wall (31) and a second side wall (31) opposite said first side wall (31), said rear wall (31) being connected to or integral with said first side wall (31) and said second side wall (31) to define a coating material recess (8) for containing coating material supplied to said mouthpiece through said conduit (15), said recess (8) preferably tapering in a direction from said top portion (T) to said bottom portion (B), said rear wall (31) having a lower edge (37) at said bottom portion (B), said first and second side walls (31, 31) each having one or more faces (SF) configured for being placed against said building surface (1) when applying said coating material contained in said recess (8) to said building surface (1). The lower edge (37) is configured for being placed against said building surface (1) together with said faces (SF) in use of said machine when applying said coating material contained in said recess (8) to said building surface (1), an elongated flexible seal (300) connected to each side wall (31, 31) extending between said bottom portion (B) and said top portion (T), for being placed against said building surface (1) when applying said coating material contained in said recess (8) to said building surface (1).

An ultrasonic injection device and methods of use are presented. The ultrasonic injection device comprises a housing, an injection nozzle attached to the housing, an ultrasonic vibration generator attached to the housing, and a pressure applicator. The injection nozzle has a number of openings configured to dispense a fluid. The ultrasonic vibration generator is configured to apply ultrasonic energy to fluid within the injection nozzle. The pressure application is configured to propel the fluid towards and out of the number of openings.
