The elongate protrusions form an amorphous pattern of a plurality of elongate two-dimensional geometrical shapes.

A plurality of elongate rods (104) include tips (108) disposed on ends of the elongate rods (104).

A first set of elongate ribs (48) intersects and joins with a second set of elongate ribs (50).

An elongated handle (12) is attached at one end to the blade body (14), which is defined by undulations to form parallel elongated ridges alternating with parallel elongated valleys.

One or more of the elongated pin elements of the array is of a different length than one or more other elongated pin elements.

A matrix is applied around the network of elongate fibers, in contact with the at least one elongate structure.

The elongated arc portions (tube) define first and second longitudinal slots extending from a top of the elongated arc portions to a bottom of the elongated arc portions.

Both extended primers can then be separated from one another and can be used to provide further extended primers.

The network of elongate fibers is placed in contact with at least one elongate structure either following or during forming the network of elongate fibers or forming the at least one elongate structure.

The photocatalytic volume 116 comprises multiple elongated structures 108 with a photocatalytic material on a surface of the elongated structures 108.

The elongate spanning cells (18) resemble long strips that extend along an entire footprint (16a, 16b, 16c).

There are structural supports upstream of the fluid outlets and between the elongated lands, to support the elongated lands.

The opening (15) is formed by elongated windows (15a) and contact cells (18) extending between pairs of consecutive elongated windows.

The elongated particles may be resin coated.

The inner turns of the elongated end portions are substantially unaligned longitudinally with the inner turns of the non-elongated end portions.
