1 bore) 32 surrounded by a thin porous substance 33. See also Specification,
2 page 15, ¶ 0035.
3 The claims read as follows [bracketed text and bold drawing element
4 numbers added].
5 Claim 1. A separation membrane 30 comprising,
6 (a) a tubular braid support 31 for a hollow 32 fiber separation
7 membrane 30 made from 16 to 60 separate yarns, each yarn being
8 between 150 and 400 denier, the tubular braid support having an
9 outside diameter between 1.5 and 2.5 mm and a wall thickness greater
10 than 0.2 mm and less that 1.0 mm, the tubular braid support 31 having
11 at least 30 picks per inch; and,
12 (b) a porous substance 33 attached to the [tubular braid]
13 support 31, the porous substance 33 covering the outer circumferential
14 surface 34 of the [tubular braid] support 31, the porous substance 33
15 being between 0.05 and 0.3 mm thick beyond the outer surface of the
16 [tubular braid] support 31 and having pores suitable for use as a
17 separation membrane.
18 Claim 8. The membrane of claim 1 wherein the air
19 permeability of the [tubular braid] support without the porous
20 substance attached is at least 1 cc/sec/cm2 at 1.378 kPa.
21 Claim 9. The membrane of claim 8 wherein the air
22 permeability of the [tubular braid] support without the porous
23 substance attached is less that about 10 cc/sec/cm2 at 1.378 kPa.
24 Claim 17. A separation membrane 30 comprising,
25 (a) a support 31 for a hollow 32 fiber separation membrane
26 made from yarns braided into a tube, each yarn being between 200
27 and 400 denier, with from 16 to 60 carriers; and,
