1. An integrated folding mechanism of a treadmill having a platform frame with a transmission motor at one side thereof for driving a continuous moving belt into rotation by use of a transmission belt, a front roller, and a rear roller, a lifting motor being employed to move an adjusting support upward and downward for adjusting the supporting angle of the platform frame, two connection pins being disposed at both sides of the platform frame, respectively, for pivotally coupling a handrail assembly and a rear support, respectively,
wherein a slide rail, on which a slipper moves, is interposed between a first and a second strengthening bar;
wherein a slide pusher is pivotally attached to the bottom of the slipper while the other end of the slide pusher is pivotally connected to the rear support;
wherein a pneumatic cylinder is pivotally coupled to the bottom of a third strengthening bar of the platform frame while the other end of the pneumatic cylinder is pivotally attached to a central crossbar of the slide pusher; and
wherein a coupling rod is pivotally interposed between the rear support and the handrail assembly. Under the action of an elastic element, the handrail assembly is movable with the platform frame for creating a synchronic folding and extending action.

The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A method for treatment of gases characterised by placing a biofilter substrate material in a vessel which is arranged to be sealed, feeding pressurised contaminated andor odorous gas into the vessel whilst it is sealed so as to increase the pressure inside the vessel above atmospheric pressure, and continuing the feeding of the pressurised gas until the inlet pressure and the internal pressure in the vessel are substantially equalised thereby ensuring a substantially even distribution of gas in the vessel and biofilter substrate material such that, the concentration of malodorous material or undesirable compounds in the gas is diminished biologically.
2. A method according to claim 1, characterised in that after a predetermined condition is reached gas is released from the vessel to reduce the pressure therein.
3. A method according to claim 2, characterised in that the predetermined condition is a gas concentration or contact or residence time.
4. A method according to claim 2, characterised in that the vessel is subsequently resealed and more contaminated andor odorous air is fed into the vessel for treatment.
5. A method according to claim 1, characterised in that the internal pressure in the vessel during treatment is 1 to 1000 kPa above atmospheric pressure.
6. A method according to claim 5, characterised in that the internal pressure in the vessel during treatment is 1 to 100 kPa above atmospheric pressure.
7. A method according to claim 1, characterised in that the pressure inside the vessel is monitored andor controlled.
8. A method according to claim 1, characterised in that the treatment is aerobic and the contaminated andor odorous gas contains oxygen.
9. A method according to claim 8, characterised in that the gas is air.
10. A method according to claim 1, characterised in that the treatment is anoxic or anaerobic.
11. A method according to claim 1, characterised in that the distribution of gas in the vessel is achieved without mechanical agitation.
12. An apparatus for the treatment of gases characterised by a vessel which is able to be sealed, the vessel being arranged to contain a biofilter substrate material, means being provided for feeding pressurised gas into the vessel, and means for releasing gas from the vessel.
13. An apparatus according to claim 12, characterised in that means is provided for monitoring andor controlling the pressure inside the vessel.
14. An apparatus according to claim 12, characterised in that means is provided for draining liquid from inside the vessel.
15. An apparatus according to claim 12, characterised in that means is provided for assessing vessel internally for insertion and removal of biofilter substrate material.
16. An apparatus according to claim 12, characterised in that means is provided for measuring the concentration of gases in the vessel.
17. An apparatus according to claim 12, characterised in that means is provided for measuring concentration of various gases or measuring the contact or residence time.
