The substrate is a polyurethane-based substrate and the transparent thermoplastic layer is polyurethane-based. The floor panel has a length of more than 1.1 meters and has a plurality of reinforcing layers situated outside the center line of the substrate. A reinforcing layer may be provided in combination with the substrate and the top layer.

According to one embodiment, the tile leveling device includes a base having a top surface and a bottom surface. The base includes a projection extending upwardly from the top surface. The tile leveling device further includes a stem detachably coupled to the top surface of the base. The stem includes a lower portion and an upper portion having a threaded portion. The lower portion is wider than the upper portion.

A tile retainer includes a base, a partition plate and a pull tab. The base includes a plurality of overflow holes. The partition plate is arranged on the base to separate a plurality of tiles disposed on the base. The pull tab is arranged on the partition plate.

A knob for a leveling spacer for laying wall tiles, floor tiles, and the like, the spacer being of the type having a base with spacing raised portions for the abutment of the edges of corresponding tiles and a stem, and the knob is provided with circumferential openings on the side wall.

Improved stripper solutions for removing photoresists from substrates are provided that typically have freezing points below about 0? C. and high loading capacities. The stripper solutions comprise dimethyl sulfoxide, quaternary ammonium hydroxide, and an alkanolamine having at least two carbon atoms, at least one amino substituent and at least one hydroxyl substituent, the amino and hydroxyl substituents attached to two different carbon atoms. Some formulations can additionally contain a secondary solvent. The formulations do not contain tetramethylammonium hydroxide. Methods for use of the stripping solutions are additionally provided.

Provided is a levelling spacer device for laying slab products for cladding laying surfaces. In some embodiments, the levelling spacer device includes a support having a base and a separator element provided with a through-window with two upper tilted sub-edges and a lower edge; and a presser wedge to be inserted in the through-window and to slide restingly on the in-view surface of the slab products, with an upper face having two adjacent areas running longitudinally along the length of the pressing wedge, and that are tilted downwards towards each other along a common convergent axis, and that cooperate, each, with a respective one of the two upper tilted sub-edges to push the slab products downwards. Also provided is a computer program product for manufacturing the presently disclosed device by 3D printing.

Support element for spacers comprising a base provided for being placed on a surface elevation pedestal, which basis is provided with at least a first and a second window having a curved geometry, each window being provided for applying therein one of the spacers in such a manner that the spacer can be freely moved in the window in which it is applied and be guided by that window when being moved, the first and second window each having a start section and a final section, the final section of the first window and the start section of the second window being juxtaposed one to each other in such a manner that a linear axis starting from a centre of the basis in a direction towards an external border of the basis crosses successively the final section of the first window and the start section of the second window.

A system and method for processing an artificial turf, and a product produced by the method, is provided. The method includes providing an artificial turf having an infill, separating at least a portion of the infill from the artificial turf, downsizing the artificial turf into artificial turf fragments and rotationally mixing and translating, by a melt system, the artificial turf fragments at a pressure less than a maximum predefined pressure to form a melt. The maximum predefined pressure is between about 0.08-20 bar.

A knob (1), for correctly laying tiles, comprises a first jaw (10) and a second jaw (20) which are connected to each other in such a way that said knob (1) can adopt a clamped configuration, in which the first and the second jaw (10,20) are in contact with each other, and a wide apart configuration, in which the first and the second jaw (10,20) are not in contact with each other.

Disclosed are a ceramic tile leveling bracket, pushing and clamping pliers and a ceramic tile leveling and laying system. The ceramic tile leveling and laying system comprises: a ceramic tile leveling bracket (1), an insertion block (2) and pushing and clamping pliers (3), wherein the ceramic tile leveling bracket (1) is provided at the junction between two adjacent ceramic tiles (4), one end of the insertion block (2) is inserted into an insertion block through hole (16) of the ceramic tile leveling bracket (1), and the pushing and clamping pliers (3) push and clamp the insertion block (2) into the insertion block through hole (16), so that an insertion block bottom surface (21) is tangent to upper surfaces of the two ceramic tiles (4). The ceramic tile leveling and laying system is easy to operate, and helps to improve the laying efficiency and laying quality.
