A spray roller system for application of architectural paints coating, includes an extension tube, a spray head mounted on a distal end of the extension tube, and the in-line valve with a trigger mounted on a proximal end of the extension tube, and a roller handle removable mounted on the extension tube adjacent the spray head. The spray roller system can spray and back roll a coating on a down stroke and roll on each up stroke. When the roller handle is removed from the extension tube, it can be used to hand roll sensitive wall areas. With the roller handle removed, extension tube, spray head, and in-line valve can be used as a spray extension to apply coatings in hard to reach areas.

Discharge ports of liquid floor finish applicators are known to clog if proper steps are not taken immediately after use. Complicating this clogging problem are the facts that floor finishes are formulated to dry quickly when exposed to air and applicator cleaning creates waste and takes considerable time and effort. Accordingly, applicant's invention addresses the problem of clogging by using a liquid reservoir to enclose the applicator's discharge port thus preventing it from clogging when not in use. To illustrate applicant's invention, a backpack floor finish applicator system dispenses liquid floor finish through a hose and a pump that forces the finish through a nozzle onto the floor. The invention uses a non-contact switch that activates a light which alerts the operator when the nozzle is exposed to air which will cause clogging thereby reminding the operator to position the nozzle within the liquid reservoir when not in use.

The present application relates to the technical field of office facilities, in particular to a temperature control structure of a laminator. According to the temperature control structure of the present application, by means of the temperature transfer shaft sleeve, the temperature transfer shaft sleeve can sense the temperature of the upper laminating roller in time so as to transfer the temperature to the temperature controller in time, and then the temperature controller controls the heating elements to be turned on or off, so that temperature control can be relatively accurate. The temperature fuse with a silicon fiber casing tube is also installed on the temperature transfer shaft sleeve, so as to achieve the effect of turning off the heating elements at a certain high temperature when the temperature controller is out of control and cannot stop heating due to other reasons.

A cleaning device has a cleaning roller that is rotatable about an axis of rotation and serves for treating a surface to be cleaned. The cleaning roller is in the form of a hollow body with an internal liquid chamber, and at least one hollow body opening for releasing liquid from the liquid chamber. In order to develop a cleaning device, in which liquid is only released from the liquid chamber to the surface of the hollow body under certain conditions, a mechanically actuated valve element is assigned to the hollow body opening, wherein the valve element can be displaced into a closing position, in which the hollow body opening is closed, and/or into an opening position, in which the hollow body opening is released, depending on the magnitude of a centrifugal force that acts upon the valve element as a result of a rotation of the cleaning roller.

A liquid applicator for applying a liquid to a surface with an improved liquid delivery process. The liquid applicator includes a container having a container body that includes an opening and a chamber that is configured to receive and hold the liquid; and, a housing assembly removably attached to the container, the housing assembly including a liquid application element and a nozzle that delivers the liquid from the chamber to the application element, wherein the nozzle is configured to deliver the liquid from the chamber to the application element when the housing assembly is positioned in a first position with respect to the container, and wherein the container body comprises an interface, a main body portion, and a base.

A tool for applying a corrosion-protection substance to a rail for securing seats in an aircraft. The tool includes a component of elongate overall shape, with a base configured to slide along the rail, and a rollers support connected to the base. The tool also has an axle incorporated in the rollers support, which extends transversally with respect to the longitudinal direction of the component on each side of the rollers support, and rollers for applying the substance mounted on the transverse axle, one on each side of the component. The tool allows the substance to be applied effectively to the flange parts of the rail that is to be protected.

A threaded adapter device couples a liquid compound applicator, such as a paint applicator, to a liquid compound container in a liquid-tight manner, where the liquid applicator and the liquid container cannot be directly joined because they have incompatible screw-on thread configurations, but the threaded adapter device provides threads compatible with the threads of both the liquid applicator and the liquid container, as well as providing a fluid channel from the liquid container to the liquid applicator.

The invention is a roller liquid compound applicator configured to attach to the threaded neck of a liquid supply container for the purpose of applying a coating of a liquid compound to a target surface, and includes: a U-shaped roller support frame including a substantially cylindrical dispenser coupling cap and a drip guard attached to the dispenser coupling cap, the dispenser coupling cap having a threaded cavity configured for mating with the threaded neck of the liquid supply container; and a liquid compound roller sleeve secured to the roller support frame.
