Definitions

  • the second ventilation area has a substantially constant width along its length.
  • the second ventilation area extends in a substantially straight line.
  • the second ventilation area has a non-uniform width and/or extends in a curved line.
  • the second ventilation area extends as an elongate diagonal area in a combination of a longitudinal and circumferential direction.
  • a first position 130 a of the second ventilation area 30 with respect to the first ventilation area 32 corresponds to a relatively low ventilation.
  • the second ventilation area 30 is aligned with a plurality of first ventilation elements 34 having a relatively low ventilating area.
  • the first ventilation elements 34 overlapping with the second ventilation area 30 in the first position 130 a are arranged in a single row.
  • ventilating area is used to refer to an effective area through which ventilation can occur, in particular an area which is both air permeable and aligned with a ventilating area of the other of the first or second ventilation area.
  • the ventilating area can be considered as an effective ventilating area selected by the other of the first or second ventilation area.
  • the first and/or second ventilation area can be considered as selecting or selected areas.
  • a same length of the second ventilation area 30 is aligned with a portion of the first ventilation area (ventilating and non-ventilating areas) from positions 130 a to 130 c .
  • This is different to the second ventilation area overlapping with an increasing area of the first ventilation area, as the first ventilation area is moved relative to the second ventilation area.
  • the present invention differs from an embodiment in which the second ventilation area overlaps from zero area of the first ventilation area to a maximum area determined by the area of the first and/or second ventilation area.
  • the ventilating area is determined by the extent of the ventilating area of the first ventilation area in a direction perpendicular to the direction of movement of the overlap with the second ventilation area.
  • the circumferential extent determines the ventilating area.
  • the overlap area can be determined by the extent of overlap in a same direction as the overlap path of movement.
  • the first ventilation elements 34 are configured to each have substantially the same area.
  • the spacing of each first ventilation element 34 is also substantially constant.
  • the change in ventilation area is provided in some embodiments only by the extent that the first ventilation area is perpendicular to the path of relative movement of the overlap with the second ventilation area.
  • the first ventilation elements 34 may each have an area and/or spacing which varies. The variation in spacing allows the first ventilation area to comprise an increasing number of first ventilation elements in the first direction per unit length. In some implementations, the spacing of the first ventilation elements decreases in the first direction.
  • the ventilation area of the first ventilation area 32 per unit length along the overlap path increases in a first direction of movement.
  • the first ventilation area 32 is configured such that an increasing ventilating area per unit length of the second ventilation area moves into overlap with the second ventilation area.
  • the ventilating area provided by an overlap between the first and second ventilation areas increases in the first direction.
  • the increase in ventilating area is not linear (i.e. not directly proportional) to the respective displacement of the first and second parts.
  • the overlap or ventilating area can increase in a non-linear manner.
  • the effective ventilating area increases as a function which increases more quickly with position than a function which is linear (proportional) (i.e. a fixed relationship or first order relationship) to the position of the first and second parts.
  • the first and/or second filter section comprises an adsorbent additive.
  • the adsorbent additive is carbon, for example, charcoal and in particular, activated carbon.
  • the adsorbent additive is a resin.
  • the adsorbent additive is distributed within the filtration material of the first filter section 12 .
  • the adsorbent additive is substantially uniformly distributed in the filtration material.
  • the adsorbent additive can be granules of carbon.
