Title: Open-end spinning unit control - uses pneumatic switch mechanism to effect stop actions on changes of internal pressure
Inventor: MUELLER PETER DR ING
IPC: D01H4/08
Filed: 1975-02-20
Abstract: A process and appts. are claimed for the control of the yarn in an open-end spinning equipment, together with control of the sliver fibre feed, in the event of a yarn breakage. A pneumatic switch unit is located in the housing for the spinning rotor, where there is a zone of underpressure. In the event of a fault, a rise in the pressure is registered and used by the switch to block the entry for the fibres into the rotor housing. The system gives a positive stop action on the fibre feed in the event of a stoppage, controlled by the conditions within the spinning zone without the problems associated with electrical circuits, and which gives an automatic stop action when the housing is opened.

Title: Water carbonation device - with annuli for water flow outside and gas flow inside porous cylinder
Inventor: GREINER WOLFGANG
IPC: B01F5/04
Filed: 1976-05-25
Abstract: In a device for the carbonation or aeration of water a cylindrical element, made of porous material, is arranged at right angles to the water inlet and outlet. An annular channel is formed along the outside of the element in which the water flows upwards; it flows downwards in the bore of the central piece and joins the outlet. The gas is admitted through bores to an annulus along the inside of the element. The porous element made of sintered CrNi steel or gauze, is built into a housing, leaving an annular gap for the incoming water. The water passes through a central bore in the centre piece. Gas, admitted through an inlet reaches an inside annulus and passes through the element pores into the water. This is a simple design and is ideally suitable for smaller installations. The element can be exchanged or cleaned in a min. of time without having to take out the whole device. It provides for more intimate mixing of gas and water.
