A powder coating device includes first-stage squeegee (11) and second-stage squeegee (12) that adjust a thickness of supplied powder (3), in which first-stage squeegee (11) and second-stage squeegee (12) vibrate at a natural frequency at a frequency from 2 kHz to 300 kHz inclusive, and second-stage squeegee (12) is shifted from first-stage squeegee (11) by a quarter wavelength of the natural frequency in a width direction of powder (3) supplied to a surface of sheet (4).

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 applicator that includes a body with a first end, an opposing second end, and an intermediate flange. An arm is connected to and extends radially outward from the body. During use, viscous material is positioned on the surface of the workpiece outward away from an opening. The first end of the applicator is inserted into the opening and a bottom side of the flange contacts against the surface of the workpiece. The arm is positioned relative to the flange to be above the surface of the workpiece with a gap formed between the bottom side of the arm and the workpiece. The applicator is rotated causing the arm to move around the opening and spread the viscous material across the surface of the workpiece.

The present invention relates to a device for manufacturing three-dimensional models by means of a 3D printing process, whereby a build platform for application of build material is provided and a support frame is arranged around the build platform, to which said support frame at least one device for dosing the particulate material and one device for bonding the particulate material is attached via the guiding elements and the support frame is moveable in a Z direction, which essentially means perpendicular to the base surface of the build platform. In so doing, the device provides a material feeding device having a particle material container to supply particulate material in batches from the storage area to the dosing apparatus and to do so with the least possible amount of shearing forces and without significant interaction with the atmosphere.

A dimensionally stable universal floor covering includes a tufted textile substrate and a reinforcement layer to provide dimensional stability for the entire floor covering. Vacuum, mixing, and injection of compressed air assists in preparing an adhesive and fiber composition to be in the preferred condition and position before the application of pressure to form the reinforcement layer. The universal floor covering is selectively cut and transported in a roll for installation, and it can be conveniently recycled if necessary.

A cap for an additive manufacturing recoater rake includes a clip portion defining a slot configured to receive a side edge portion of a recoater rake, and an angled surface extending from the clip portion. The angled surface is configured to contain powder pushed by the recoater rake on the powder bed.

A coating film forming apparatus includes a substrate holding unit, a ring-shaped member annularly installed along a circumferential direction of the substrate so as to cover an upper side of a peripheral edge portion of the substrate, and a control unit that outputs a control signal so as to perform: positioning the ring-shaped member at a processing position where an air flow flowing above the peripheral edge portion of the substrate is straightened; rotating the substrate at a first revolution number such that a coating liquid supplied to a central portion of the substrate is diffused toward the peripheral edge portion by a centrifugal force; bringing the ring-shaped member to a retreated position where an air flow flowing near a front surface of the substrate is prevented from becoming turbulent; and reducing the revolution number of the substrate to a second revolution number lower than the first revolution number.

A dimensionally stable floor covering, comprising a tufted textile substrate and a reinforcement layer wherein vacuum is used to move adhesive into stitch portions of the yarns and into the back side of the primary backing substrate to provide increased dimensional stability for the entire floor covering. Mixing of reinforcement fibers and adhesive takes place before in situ filtration of the adhesive and fibers. Further, compressed air is injected into the adhesive/fiber composition to provide spaces between the fibers before application of pressure to the composition. The vacuum, mixing, and injection of compressed air assist in preparing the adhesive and fiber composition to be in the preferred condition and position before the application of pressure to the composition.

The disclosure relates to a spreading unit having a shaper for spreading viscous material, in particular sealing material, on a component, wherein the shaper has a first shaping contour for shaping the viscous material in the process of the spreading, wherein at least a second shaping contour of the shaper for shaping the viscous material can be brought by means of an actuator, in a direction of spreading, into superimposition with the first shaping contour, so that a shape of the shaper is adjustable during an application process.

The present invention relates to a device for manufacturing three-dimensional models by means of a 3D printing process, whereby a build platform for application of build material is provided and a support frame is arranged around the build platform, to which said support frame at least one device for dosing the particulate material and one device for bonding the particulate material is attached via the guiding elements and the support frame is moveable in a Z direction, which essentially means perpendicular to the base surface of the build platform.
