The tubes have at least one opening which extends through the entire length of the tubes.

Tube lengths shall be minimized as far as possible

The length of the tubes of each tube group block may be reduced so that the tube group blocks when connected have a predetermined size.

This allows the Kapinos adapter to move freely along lengths of the said tubes.

According to a preferred embodiment the outer pipe is separated from the inner pipes by a gap over at least a part of the length of the inner pipes.

An integral snap button and anti-rattle member is provided for locking the length of and decreasing the play and rattle between inner and outer tubes of an adjustable-length telescoping tube assembly.

The length of the tubes and the angles define the steering style.

Substantially sine wave undulations (U) are formed in the panel (302) with the direction of the wave extending along the tubes (304), each tube (304) having the same undulation.

Multiple ports along the length of the tubes provide differential pressure readings.

The reactor (10) also includes a thermal insulator (90) along a length of the tubes (50) at a large temperature gradient zone within the reactor (10).

A plurality of micro-channels is provided side by side along the length direction of the tubes (11) in each flat tube (11).

These forward collets are supported for travel along a track (5) by a distance equivalent to the length of the tubes.

Coaxially arranging several tubes (8) behind each other is problematic insofar as tolerances in the length of the tubes (8) result in a positioning error of the take-up means (8.1), thereby decreasing the take-up accuracy.

The both parallel tube plates (4) and (5), which belong to one module, are provided with a sleeve (1) on the external circumference thereof over the whole length of the membrane tubes (3).

Most manufacturers will at a minimum include size, head and seat tube lengths, top tube length, wheelbase and chainstay length.
