A tow 10 of parallel filaments is fed by feed rollers 20, 22 to fracturing means which comprise a roller 26 having blunt helical flutes 60 and an anvil roller 24, e.g. of hardened steel. Rollers 24, 26 rotate at a higher speed than rollers 20, 22 so that the filaments are fractured under tension. The filaments which are fractured but not completely severed into staple are then fed to a card, e.g. by a conveyor 62, in which the fractured filaments are broken up into staple fibre, the dust from the fractures is removed and a web is formed. Several, e.g. four slivers may be fed through the apparatus in spaced non-contacting relation, separate, fracturing rollers 26 being provided for each sliver. The delivered webs are each condensed by vertical rolls 30, turned through 90‹ by bars 80 and fed onto overlying guide plates arranged at four different heights. Cotton sliver webs from four other cards are then introduced to interleave with the synthetic staple webs, the webs then being brought together and drafted. Rollers 26 are individually mounted on plates 53 rotatable about a shaft 56. A pivoted plate 54 is normally locked in position above the plates 53 and a pneumatic tube 58 placed between the plate 54 and the plates 53 so that the rollers 26 are similarly loaded but independently moveable. To prevent fibres becoming embedded in the teeth on the main cylinder 38 a duct 70 is provided on a cover 72 which precedes the doffer 42. Pressurized air is fed to the duct and through a line of holes in cover 72 onto the fibres on the cylinder. This is said to lift the fibres from the cylinder.

Title: Determining the velocity of a sound wave in an ionised gas  and the temperature in the gas

Abstract: 1332933 Measuring velocity of a sound wave and temperature LOUGHBOROUGH CONSULTANTS Ltd 19 April 1971 [13 Feb 1970 7005/70 Heading G1N A sound wave is produced in an ionized gas by positioning a pair of mutually spaced electrodes in the gas so that a plasma sheath forms at each electrode and applying a first alternating electrical signal from a generator to a first of the electrodes so as to change the sheath thickness resulting in a flow of neutral gas molecules which replace the ions removed from the plasma and give rise to a disturbance which propagates the wave. The VELOCITY OF THE WAVE is determined by receiving the wave at the second electrode to produce an electrical signal therein and applying the first and second signals to a phase detector. By increasing the frequency f of the generator and noting the maxima and minima of the phase detector output corresponding to additional half wavelengths of the wave between the electrodes a graph of f against K (no. of waves per cm) can be plotted the slope of which gives the sound velocity C. DRIFT VELOCITY may be determined by repeating the process with the roles of the electrodes reversed and subtracting the two values from each other to give twice the drift velocity. ABSOLUTE TEMPERATURE, T can be obtained from the sound velocity C and molecular weight of the gas M, determined experimentally, using the formula C<SP>2</SP> = γRT/M. Alternatively TEMPERATURE CHANGES as a function of time may be obtained by applying a fixed frequency to the first electrode and detecting the change in phase angle # with time, any change in temperature changing the wave velocity in the gas (T = 4 #<SP>2</SP> Md<SP>2</SP> f<SP>2</SP>/γR#<SP>2</SP>, where d is the spacing between the electrodes). The effect of drift in the gas may be erradicated by using two receiving electrodes spaced equally from a central transmitting electrode.
