Title: Syphon system - uses contracted and expanded air to maintain water pressure in maintenance-free pump or desalination functions
Inventor: CANSTEIN CARL-MAGNUS VON
IPC: B01D5/00
Filed: 1991-03-06
Abstract: The syphon system, to control the tension applied to the water in a solar pump operated by solar thermal energy and desalination plants, uses contracted and expanded air in a hollow zone at the water energy and exit points to deliver a given vol. of water while cooled at night or heated by day, according to each cycle. In the suction cycle, the wt. of the water column in the syphon bears on the part to be pumped out. In the pumping cycle, the displacement pressure works in the air column in the suction tube, which has its opening correspondingly deep below the water surface, such as at the deepest point in the syphon. The entry tube has to be at or above the water surface, of the water to be pumped, at the centre level of the hollow body, so that water from the inlet is caught at the lower section of the hollow body. This operation applies for a pure pumping function where, in desalination the water runs into an intermediate basin in the hollow zone for evaporation and then condensation at the inner wall, or for pure drinking water to be forced outwards by the syphon from below. ADVANTAGE - The system requires no maintenance over long periods, to give an automatic operation over a long time scale.

Title: Automatic winder - has checks on number of cuts in yarn at winding bobbin and has controlled test pulses to test yarn cutter
Inventor: SCHULTZ WALDEMAR
IPC: B65H63/06
Filed: 1991-07-12
Abstract: A sensor monitors the operation of a winding station, at an automatic winder, by the quality of the yarn affected by cutting when the standard drops below permissable levels, and the number of cuts per bobbin are counted until the bobbin is doffed. After a given number of supply or winding bobbin changes, the winding station resumes working when a yarn is at the sensor and pref. when the upper yarn of the winding bobbin is joined to the lower yarn of the supply bobbin, and a control unit generates a test pulse. The test pulse is stored at the start of the signal path of the sensor monitoring the yarn quality, to trigger a cutting action. The sensor registers the presence of a yarn at the monitoring point. An interruption in the yarn travel is checked by the control, and the cutter is closed when the yarn is moving, on transmission block of the test pulse and on a function failure so that the winding station is blocked and a fault signal is developed. ADVANTAGE - The operation gives a more comprehensive check on the working of the winding station and protects the delicate cutting system.
