Abstract: The current invention relates to a filtration membrane envelope (3) comprising a 3D spacer fabric (7) having an upper and lower surface (9, 10) tied together and spaced apart by monofilament threads (11), said 3D spacer fabric is interposed between two membrane layers, and forming a permeate channel (12), wherein said membrane layers are cast respectively on said upper and lower fabric surface of said 3D spacer fabric and wherein said upper and lower fabric surfaces are at least partially embedded in said membrane layers, thereby forming an upper and lower anchorage section (13, 14), characterized in that said anchorage section have a minimal thickness of 100 micron.

Abstract: The current invention relates to a filtration module for the purification and/or filtering of a fluid such as water or wastewater: said module comprises a plurality of filtration membrane envelopes, which are vertical, parallel, and spaced to one another in a rigid holder, wherein each filter membrane envelope has an end portion covered by a U-shaped cap, characterized in that, said cap is a metal cap, preferably a stainless steel cap.

Abstract: A liquid discharge head includes a liquid discharge unit, a housing, an electrical connection portion, and a connection portion cover member. The liquid discharge unit discharges liquid, the housing covers the liquid discharge unit, and the electrical connection portion is electrically connected to an electrical wiring substrate of a recording apparatus. The connection portion cover member covers the electrical connection portion. Power is supplied from the recording apparatus to the liquid discharge unit via the electrical connection portion. The housing includes a recessed portion into which the connection portion cover member is to be inserted. The connection portion cover member includes an insertion portion insertable into the recessed portion. The insertion portion is covered by the recessed portion.

Abstract: An energizing element including: an energizing element body oriented about a central axis, the energizing element body defining an inner radius, IR, and an outer radius, OR, where the difference between the outer radius and the inner radius defines an adjusted width, W, of the energizing element body, where the inner radius and the outer radius determine an average radius, R, of the energizing element body about the central axis, where the energizing element body defines an aspect ratio, W/R, where W/R>0.1, where the energizing element body has a maximum linear contact length on the inner radius, LIR, where the energizing element body has a perimeter on the inner radius, PIR, and LIR/PIR>0.80, where the energizing element body has a maximum linear contact length on the outer radius, LOR, where the energizing element body has a perimeter on the outer radius, POR, and LOR/POR>0.55, and where the adjusted width is less than 5 mm.

Abstract: An energizing element including: an energizing element body including an annular filament oriented about a central axis, the annular filament including a plurality of oscillations generally directed down the central axis, where at least one oscillation includes an internal circumferential void having a first circumferential width, WFV, and a second circumferential width, WSV, located at a different axial position along the oscillation, and where WFV?WSV.

Abstract: A seal assembly comprising: a housing defining a groove; a seal disposed in the groove of the housing; and a coupling element adapted to restrict relative movement between the housing and the seal.
