Title: Method of evening out thickness tolerances in blown film tubing - by mounting regulating devices on circular support divided into many identical segments and turning the support through half one segment length
Inventor: HALTER HARTMUT
IPC: B29C48/92
Filed: 1992-06-10
Granted: 1993-12-09
Abstract: In the operation of a blown film/extruder layout for the prodn. of plastic film thermoplastic tubing is extruded, blown out, laid flat and wound into a reel. The equipment used has a blowing head with annular nozzle and inner and outer annular lips on the nozzle for the extruded tubing to emerge from; a device inflates this extrusion to the blown film; a device with circulating cooling air provides exterior cooling; the nozzles lips and/or cooling systems in circular and divided into equal segements; the centres of the segments have devices to adjust the transverse tolerances across the film to the residual tolerance profile; the devices concerned are fixed to a support; and the adjusting devices also measure the deviation of the transverse tolerances from their nominal values. The measured values are related to their segments; if a systematic and unacceptable deviation arises in the transition area between two segments the support mentioned is turned through half the length of a segment, and the deviation is evened out by the adjusting device. ADVANTAGE - Systematic thickness errors exceeding residual tolerances and appearing in the profile of the residual tolerances can be evened out, so that the profile of the residual tolerances is no longer unacceptably exceeded. (Tests have show that the systematic errors are caused by the arrangement of the regulating units themselves).

Inventor: ALBRECHT JOERG DIPL ING
IPC: H02P6/14
Filed: 1993-03-30
Granted: 1994-09-08
Abstract: An electronic control device for an electric motor (10) especially a DC motor, is proposed, whose motor windings (11-13) are each connected in series with control transistors (15-17) in order to control the winding current, the control connections of which control transistors have control signals supplied to them which are triggered by a commutation signal and have a duty ratio which can be predetermined (block control).
