摘要:
A method of, and apparatus for sampling a solid or liquid sample using a sampling tool which has a sampling rod/tube that is configured to house a sampling pod (10), the apparatus comprising: a main body portion (12) with at least one sample collecting cavity (14); and a removable/opening lid portion (16) that in use fits/closes over at least part of said main body portion and thereby covers and the cavity; the method further comprising the following steps: (a) Inserting said sampling pod main body portion within said sampling rod/tube and taking a solid or liquid sample from a vessel/container; (b) removing sampling rod/tube from said vessel or container and covering said collecting cavity to seal said cavity; (c) transporting said sample within said sampling pod to place of a analysis; and (d) at place of analysis removing at least part of said covering from main body portion to expose sample for analysis.

A vehicle (10, 200, 300) comprising a frame, a front wheel and at least one rear wheel; and directly or indirectly attached to said frame, a front seat that faces forwards such that in normal use a first rider can sit thereon and to steer the vehicle as it moves forward and a rear seat for a second rider that faces backwards; having a rear rider crank assembly (42,44) and a front rider crank assembly (36) and where a wheel hub (52) and a connected rear sprocket (46), or sprocket bush (56) and a connected rear sprocket (46), are rotatably mounted around the crankshaft (42) of the rear rider crank assembly such that in use pedal power from a rear rider is first transmitted through the rear pedals (34) and rear crank assembly, via a cross-over drive chain (38), to the front rider crank assembly.
摘要:
A dispenser for dispensing a viscous fluid stored directly within the body of the dispenser, or within a cartridge inserted within the dispenser in which the viscous fluid is forced through a dispensing aperture by advancing a piston member and where the piston is advanced by turning a first thread member that locates in the female thread of a main body member and where upon completion of such turning resilient means are provided to partly reverse the direction in which the first thread member was turned and so avoid unwanted flow of fluid following completion of such turning.
摘要:
A ground surface access assembly frame (10, 110) surrounding and defining an aperture; said frame comprising sidewalls (12, 112) that extend downwardly to connect to an outwardly extending flange portion (14, 114) and further comprising a key-engaging member (16, 116) that extends upwardly from said support flange portion and comprises a pair of spaced-apart slots/recesses (18, 118) that allow engagement of a lifting key (K) by firstly sideways movement and then secondly upward movement of said key (K).
摘要:
An improved ceiling mount assembly (10) for supporting a connected electrical device so that it can be temporarily lowered from a ceiling to facilitate servicing comprising: an upper member (12); a lower member (14); and a tether line (18), the first end of which is connected to a mechanical (non-motorised) extension/retraction unit (16) within the upper member (12; and the second end of which is attached to the lower member (14); such that in use when said electrical device (E) is mounted underneath the lower member, both may together be raised or lowered relative to the upper member that is fixed to the ceiling (C).
摘要:
An energy conversion process that exports by-product CO2 at elevated pressure where a fuel gas feed stream is mixed with a reactant stream and additional CO2 is added to at least part of, the fuel gas feed stream, the reactant stream or both through desorption by contacting with a CO2-rich solvent stream in a first stage contactor to produce a mixed feed gas stream and a CO2-lean solvent stream; passing said mixed feed gas stream to a chemical conversion step, where further CO2 is produced; chilling at least part of the products of said chemical conversion step and thereby produce a CO2-lean gas stream; and passing at least part of said CO2-lean gas stream said to a second stage contactor where further CO2 is removed, by absorption, to produce a product gas stream and a solvent stream rich in CO2 from which said CO2-rich solvent stream is subsequently derived.
