Filed: 1960-02-22
Abstract: <PICT:0942754/C1/1> Relates to a method of, and apparatus for, aerating water in lakes 10, pools and aquaria in which a below-surface water current 52 produced by a submerged motor 28 driving an impeller 24 entrains air drawn from above the surface 16 through a pipe 42 connected to a float 40. The water enters through a strainer 26 and is passed to a header 34 with risers 36 connected to Venturi nozzles 38 with air inlets from a header 44. The nozzles are adjustable for direction laterally and vertically and may be made to turn or sweep intermittently or continuously by means not shown.  The operation of the motor 28 may be intermittent; cont.rolled from the shore or by a timer 30. Most of the air is entrained in small bubbles which subsequently dissolve; but some large bubbles 54 are formed which keep the water surface 16 free from ice or scum 58.  The Specification states that water picked up by the impeller 24 from the bottom is of a different temperature and density than that surrounding the nozzles 38 so that the "shaft" of water ejected by the nozzles does not readily mix with the water into which it is discharged.  An embodiment in which a sealed motor drives a simple propeller under water and air is received on the low pressure side of the propeller through a pipe from the surface (Fig. 4, not shown).  A regulating valve may be included in the air inlet pipe.

A method of cleaning spinning chambers in break-spinning machines is characterised in that the air flow, by which separated fibres 8 are fed into the spinning chamber, is imparted a pulsing motion, after deflection from a wall 15 which slopes towards a collecting surface of the chamber before escaping through vents 17, by at least one stationary projection 18 extending into the chamber. The body 19 of a separating mechanism 1 is provided with a channel 9 inclined to the direction of feeding fibres 8 from the separating mechanism, the channel 9 opening at one end into the ambient atmosphere and at the other end in a direction substantially perpendicular to the wall 15 of the chamber. The projection 18 can be in the form of a wing 20 or a rib. The yarn produced at point 16 is withdrawn from the chamber via hollow screw set in the body part 19 of the separating mechanism. The pulsing motion imparted to the air flow prevents dirt entrained in the fibres from settling and the dirt is carried away on the air flow via vents 17.
