The invention relates to an anchor for arrangement in lightweight building boards, wherein a lightweight building board has a first covering layer and a second covering layer made from compact material that is stiff in compression, and a core layer, which is arranged between the covering layers and is made from material with a low density in comparison with the covering layers, in particular paper honeycomb, foam or solid wood of low density, having a first anchor part and a second anchor part, wherein the first and the second anchor part are designed to be movable relative to one another, in which a travel between a first end position and a second end position is limited, wherein the first end position is defined by means of first stop means on the first and the second anchor part, and the second end position is defined by means of second stop means on the first and the second anchor part.

A method for joining two objects by anchoring an insert portion provided on one of the objects in an opening provided on the other one of the objects. The anchorage is achieved by liquefaction of a thermoplastic material and interpenetration of the liquefied material and a penetrable material, the two materials being arranged on opposite surfaces of the insert portion and the wall of the opening. Before such liquefaction and interpenetration, an interference fit is established in which such opposite surfaces are pressed against each other, and, for the anchoring, mechanical vibration energy and possibly a shearing force are applied, wherein the shearing force puts a shear stress on the interference fit.

Novel or improved microporous single or multilayer battery separator membranes, separators, batteries including such membranes or separators, methods of making such membranes, separators, and/or batteries, and/or methods of using such membranes, separators and/or batteries are provided. In accordance with at least certain embodiments, a multilayer dry process polyethylene/polypropylene/polyethylene microporous separator which is manufactured using the inventive process which includes machine direction stretching followed by transverse direction stretching and a subsequent calendaring step as a means to reduce the thickness of the multilayer microporous membrane, to reduce the percent porosity of the multilayer microporous membrane in a controlled manner and/or to improve transverse direction tensile strength.

A method of forming a component includes additively manufacturing a first subcomponent, the first subcomponent including a first polymer material with a first porosity. The method further includes mating the first subcomponent with a second subcomponent and ultrasonically welding the first subcomponent to the second subcomponent at a weld frequency. The first porosity can be 5% or less.

Methods of making membrane elements for fluid or gas filtration, comprising applying feed or reject spacers, or intermediate spacers, or fold line protection strips, or end support strips directly to a membrane sheet, or to a substrate material which are subsequently applied to a membrane sheet, which thereby avoids contamination from directly printed adhesives, inks, or polymers, or damage from heat or radiation damage to the membrane sheet during direct application of spacers or patterns to the surface of the membrane sheet, thereby avoiding utilization of conventional feed spacer mesh materials. Membrane sheets and spiral wound filtration elements having spacers applied to defined regions of the sheet, in some embodiments having spacers mounted on substrates with different material properties, e.g., stiffness, than the underlying membrane.
