A flow detector for monitoring an adhesive flow in an adhesive applicator includes a sensor device arranged in the adhesive flow. The sensor device is formed as a capacitive sensor.

This invention relates generally to a nozzle, method thereof and a kit set for the same for spreading material on curved surface, in the field of repairing services for wind turbine blades and other similar composite components. More particularly, the present invention relates to a nozzle for spreading material on a leading edge of a wind turbine blade for guiding the material along the surface, generally, for repairing or upgrading. In addition it relates to a method and a kit for performing the application.

Systems and methods for preparing covalent organic framework (COF) thin films is disclosed herein. The systems and method utilize COF colloidal inks, having a diameter of 10-1000 nm, expelled through a nozzle onto a substrate to prepare the COF thin film. The plurality of COF colloidal ink droplets have an effective deposition diameter from the nozzle onto a masked or unmasked substrate, where the substrate may be heated to an effective COF deposition temperature.

An inkjet print apparatus includes a stage; an inkjet head located over an upper portion of the stage, configured to move in a first direction and a second direction opposite to the first direction, and configured to eject an ink toward the stage; a first ultraviolet irradiator located behind the inkjet head with respect to the first direction first covers located at respective sides of the first ultraviolet irradiator in the first direction; a second ultraviolet irradiator located behind the inkjet head with respect to the second direction; and second covers located at respective sides of the second ultraviolet irradiator in the second direction. Further, a process for forming an adhesive layer may be simplified by using an inkjet printing method.

A method of making a floor covering including a tufted textile substrate and a reinforcement backing system. A layer of reinforcement fibers is positioned on the ends of yarn stitches. Applicators are operationally connected such that adhesive is forced into the reinforcement fiber layer towards a primary backing substrate, and adhesive is also substantially simultaneously directed to form a pool of adhesive between the applicators, and a portion of the pool of adhesive is also substantially simultaneously applied as a layer of adhesive on the reinforcement fiber layer.

A fence painting system enables applying a coating to a both the front and back of the fence simultaneously. The system uses spray modules mounted to an anchor to apply the coating. The anchor attaches to the top of the fence and lowers the spray models with an extension device. The modules detect the ground as they descend with a sensor that prevents the modules from impacting the ground.

A coating system (1) is provided which includes an ultrasonic sprayer (3) capable of spraying a coating fluid onto a target surface (5). A convective or infrared heater (21) is associated with the sprayer and is operable to heat the spray (23) produced by the sprayer (3).

Systems for the manufacturing of waveguide cells in accordance with various embodiments can be configured and implemented in many different ways. In many embodiments, various deposition mechanisms are used to deposit layer(s) of optical recording material onto a transparent substrate. A second transparent substrate can be provided, and the three layers can be laminated to form a waveguide cell. Suitable optical recording material can vary widely depending on the given application. In some embodiments, the optical recording material deposited has a similar composition throughout the layer. In a number of embodiments, the optical recording material spatially varies in composition, allowing for the formation of optical elements with varying characteristics. Regardless of the composition of the optical recording material, any method of placing or depositing the optical recording material onto a substrate can be utilized.

A method of depositing an extrudable substance onto a surface. The method comprises the step of delivering the extrudable substance from a cartridge to a flow-bypass assembly. The method further comprises the step of selectively controlling the flow-bypass assembly to purge air from the extrudable substance before the extrudable substance enters a delivery tube. The method further comprises the step of selectively controlling the flow-bypass assembly to deliver the extrudable substance from the flow-bypass assembly to a valve assembly via the delivery tube. The method further comprises the step of controlling flow of the extrudable substance from the valve assembly to a nozzle.

An apparatus for depositing an extrudable substance onto a surface. The apparatus comprises a bracket, comprising an opening that has a central axis, and a tubular sleeve, coupled to the bracket via the opening and rotatable relative to the bracket about the central axis. The apparatus further comprises a valve assembly, comprising a valve body, fixed to the tubular sleeve and rotatable relative to the bracket together with the tubular sleeve, and a valve, internal to the valve body. The apparatus also comprises a linear actuator, configured to position the valve relative to the valve body. The apparatus further comprises a nozzle, fixed to the valve body and rotatable relative to the bracket together with the valve body.
