A reversible corner shield apparatus and methods of use, v-shaped or angled shaped shield having a first linear shield member or wing and a second linear shield member or wing which are connected or joined at an apex therebetween, a mount or connector positioned proximate the apex between the first linear shield member or wing and a second linear shield member or wing, a hinged connector attached to the mount on a first end of the hinged connector and an elongated handle connected to a second end of the hinged connector to enable rotation between the handle and the shield and, thus, functions to assist a solo painter in rotating and positioning the shield around inner and outer corners of flooring, baseboard, door and window trim or ceiling to shield these non-painted surfaces from over-paint, over spray, uneven transition lines, unsightly paint dabs and the like.

A system including an adhesive dispensing device and a charger base. The adhesive dispensing device includes a first light emitting device, a handle, a power source, and a power supply interface. The charger base includes a second light emitting device, an interface formed for receiving the adhesive dispensing device, an external power output interface, and a power supply circuit. The external power output interface is configured to electrically couple to the power supply interface of the adhesive dispensing device. The first light emitting device is configured to illuminate in response to power being provided to the power supply interface from the power supply circuit. The second light emitting device is configured to illuminate in response to power being provided to the power supply circuit from the external power output interface.

The embodiments disclose an apparatus including a dispenser having an elongated compartment configured to contain a liquid solution, a liquid solution contained in the elongated compartment configured to suspend solid nanoparticles in an evaporative liquid, a dispenser handle configured to twist to push a predetermined amount of the liquid solution from the elongated compartment out of an open tip orifice, and at least one applicator tip insertable into the tip orifice configured to receive from the elongated compartment the predetermined amount of the liquid solution to spread over a user's mobile device glass screen.

An extensible adhesive dispensing gun system. A syringe has a piston for urging an adhesive out of a nozzle, and a first mount at a back end of the syringe. A gun body contains a mechanism for advancing a plunger from a front end of the body in response to a trigger, and a second mount is disposed on the front end. An extension tube assembly includes an outer tube having near and far end adapters. A third mount on the near end adapter engages the second mount on the gun body, and a fourth mount on the far end adapter engages the first mount on the syringe. An inner rod member is arranged inside the outer tube. When the gun plunger is urged against a back end of the rod member, a leading end of the member forces the syringe piston to urge the adhesive out of the nozzle.

A dispensing nozzle is disclosed herein. The dispensing nozzle includes a hollow enclosure defining an inner chamber. A fluid dispersion element is arranged within the inner chamber and includes a fluid inlet having at least two orifices that respectively open into and communicate with an associated fluid dispersion channel. Each fluid dispersion channel has a reduced cross section from that of the fluid inlet and are arranged to disperse flow of materials received at the fluid inlet into parallel streams of flow prior to recombination of the materials at the nozzle outlet.

A system for finishing surfaces with a finishing material includes a handle assembly with proximal and distal ends. A material reservoir is mounted on the handle distal and includes an inlet and an outlet. A material applicator tool is mounted on the reservoir and receives material from the reservoir outlet. A discharge mechanism includes an extendable-retractable component or linear actuator connected to the reservoir for discharging or reloading material. An alternative embodiment includes a lockable, compressible gas spring. Another alternative embodiment includes a rotating element driven by a reversible motor mounted on the handle assembly. The rotating element drives a discharge mechanism in a discharge direction of rotation, and reloads the reservoir in a reload direction of rotation. Multiple alternative embodiments of linear actuators are disclosed. An alternative embodiment includes a push-to-open valve mechanism.

A cartridge for a viscous-material dispenser includes a cylinder and a plunger axially slidably fitted in the cylinder and dividing the cylinder into a filling chamber and a pressurizing chamber and includes a plurality of solid spacers in an annular gap between the plunger and the cylinder for maintaining a minimum spacing between the plunger and the cylinder. The spacers at least partially define a plurality of passages that fluidically connect the filling and pressurizing chambers and are configured such that a first portion of the viscous material extending from the filling chamber into the plurality of passages forms a seal together with the solid spacers to prevent a second portion of the viscous material located in the filling chamber from entering the plurality of passages.

Described herein is an apparatus for applying and curing a light-curable material on a work surface. The apparatus includes a nozzle from which the light-curable material is applied to the work surface to form a layer of light-curable material on the work surface. The layer of light-curable material has a leading edge and a trailing edge defined according to a direction of movement of the nozzle relative to the work surface. The apparatus also includes a light source fixed relative to the nozzle. The light source is operable to direct a light beam to the trailing edge of the layer of light-curable material.

Systems for removing gas from a sealant and transferring gas-less sealant to an applicator are provided. The system may comprise: a rotatable chamber including: a first opening for receiving sealant; a hollow conduit arranged such that when gas accumulates in the center of the rotatable chamber when the rotatable chamber is rotating, the gas is ventable from the rotatable chamber; a second opening for receiving gas-less sealant from the rotatable chamber after the gas is vented from the hollow conduit; and a motor operatively configured to rotate the rotatable chamber; and a gas-less sealant applicator in fluid communication with the second opening of the rotatable chamber such that gas-less sealant released by the second opening is flowable into the applicator. The system may also include a robot arm including an end effector with a sealant dispensing nozzle. A method for applying sealant to an aircraft structure is also provided.

The present invention is an expandable caulking gun having a distal end and a proximal end which receive a caulking cartridge with a caulking material comprises of a cartridge-holder extended from the distal end to the proximal end to receive said caulking cartridge; a trigger mechanism at the distal end to push a push-rod; a display holder adjustably attached to a top portion of said trigger mechanism; a camera adjustably attached to said proximal end and having a communication means to connect to a handheld device; whereby a user places said handheld device on said display holder and connects said camera to said handheld device to observe a surface or grooves located a distance from said user while applying said caulking material.
