A grafted polyvinyl alcohol polymer includes a polyvinyl alcohol main chain and a plurality of side chains grafted to the polyvinyl alcohol main chain. One or more of the side chains from the plurality of side chains include one or more units selected from: an aliphatic carboxylic acid, an aliphatic amide, an amino alkyl (meth)acrylate, a hydroxylated alkyl (meth)acrylate, or any combinations thereof. The grafted polyvinyl alcohol polymer can be included in a formulation that also includes water, and the formulation can be used as an adhesive in a creping process.

Method for producing arrays of free standing, three dimensional structures on material surfaces by establishing contact with a template, moving the template and the surface in contact relative to one another, inducing an increase in viscosity such that the structures are self-supported, and removing the template, leaving a negative of the template geometry at the tip of the object.

The present invention is directed towards a window sill flashing comprising a base having a substantially rectangular shape. A front flange projects perpendicularly downward from a front edge of the base and at least one side flange extends vertically from a side edge of the base. The side flange includes a front surface. The window sill flashing is made from a rigid homopolymer vinyl film.

The present disclosure provides a method for preparing a self-floating transparent nano ultrathin film. According to the present disclosure, the MXene film layer and the nano ultrathin film layer are sequentially subjected to suction filtration on the substrate material by utilizing a vacuum suction filtration technology, and thus a double-film structure is loaded on the substrate material; then an oxidant is subjected to oxidizing and bubbling on the MXene film layer in a permeation way, and thus the substrate material and the nano ultrathin film layer can be separated in a physical isolating manner. Finally, the nano ultrathin film is completely separated in a liquid phase floating separation manner. The nano ultrathin film prepared by the method provided by the present disclosure has a specific thickness and light transmittance through different loading capacities, and the substrate material can be repeatedly utilized.

A system for peen-forming of thermoplastic composite material is provided. The system includes a tool, a heater, and a peen-forming device. The thermoplastic composite material is positioned on the tool, which supports the thermoplastic composite material as it is being process. The tool has a surface to which a portion of the thermoplastic composite material is intended to conform. The heater is configured to heat the thermoplastic composite material while it is positioned on the tool to make the thermoplastic composite material more malleable. The peen-forming device directs particles against the thermoplastic composite material positioned on the tool so that the portion of the thermoplastic composite material conforms to the surface of the tool.

A method for producing a composite glass pane, includes placing a first glass pane having a thickness less than or equal to 1 mm on a support mould, wherein the first glass pane is curved into a shape determined by the support mould; placing at least one thermoplastic film on the first glass pane; placing a curved second glass pane having a thickness greater than or equal to 1.5 mm on the thermoplastic film; and joining the first glass pane to the second glass pane via the thermoplastic film to form a composite glass pane by lamination.

An optically shaping apparatus includes a light modulation element having a plurality of pixels and configured to modulate light from a light source for each pixel, an optical system configured to irradiate modulation light from the light modulation element onto the photocurable resin through the light-transmissive portion, a controller configured to control the light modulation element based on each of a plurality of two-dimensional shape data corresponding to a plurality of sections in a three-dimensional object, and a moving member configured to move a cured portion cured by the modulation light among the photocurable resin in a direction separating from the light-transmissive portion. The controller controls an irradiation timing of the modulation light onto the photocurable resin for each pixel to form the cured portion corresponding to the same section in the three-dimensional object, in accordance with information on a shape of the light-transmissive portion.

In the world of bear spray, options for holsters are almost nonexistent. Manufactures of bear sprays offer holsters that are designed to be inexpensive, and mass produced. Most of these holsters require the use of a belt, something a lot of people are not wearing while they are hiking, hunting, or camping. The current options available completely lack versatility to the users preferred attire and are of a disposable nature. I felt that if a product as wonderful as bear spray is to work to save humans and bears lives it must be able to be carried in a comfortable user-friendly holster that has different attachment options that will work with the attire that the user is going to be wearing. It needed to be in a holster that retains and protects the canister and allows for lightning fast draws in dangerous situations. I worked hard to create a holster that is high quality, durable, and aids to assist preform the task of quickly deploying bear spray in high stress, emergency situations. Holsters are as much of the protection system as the canister of bear spray itself.
