Title: Rolled material winding - uses structured and controlled movement from final roller stand to give wound ring shapes with tight tolerances
Inventor: GOERICKE ROLF
IPC: B21C47/04
Filed: 1990-11-06
Abstract: To wind strip material into bodies with rotational symmetry and in tight tolerances, in light section rolling mills with increased levels of dimensional stability in the delivered ring-shaped rolled material, the material is formed into loops after the final roller stand by a mechanism with rotary speed control matching the speed of roller and rod travel. This forms a horizontal loop with a storage capacity where the instabilities of the winding process match the dynamic characteristics of the winding assembly drive, without affecting subsequent machine stations. The draw tension applied by the winding action is compensated at preceding assemblies. The brake-drive system with peripheral contact on the material to support the catch process at the winder, is set to a forward rotary motion in a drive action and, when the material is caught, it is switched to a braking mode where the nominal rotary speed is reduced by 3-10% in relation to the rod travel speed. The current for the advance drive and the preset speed level acts as a guide drive matching the winder rotary speed. The position of the loop is controlled by variations in the winder rotary speed. The loop control starts when the material has been caught and ceases when the end of the material has passed through the looper. After the rolled material has emerged, the rotary speed of the looper drive is shifted to a nominal value, and then switched back after intermediate braking to direct the low speed material into the winder and then finally stopped. ADVANTAGE - The operation maintains the material dimensions and surface quality while winding into ring shapes with narrow tolerances.

Title: Demultiplexer for digital signal transmission system - has decoder, transmitting coincidence, or anti-coincidence, signal w.r.t. to bit patterns
Inventor: KOCH WERNER DIPL ING
IPC: H04J3/06
Filed: 1990-11-24
Abstract: The demultiplexer carrier and a series parallel conversion of input data flows with a frame structure by a series data cycle shift register (10) and a parallel data cycle matrix memory (20). A decoder (40) on coincidence or anti-coincidence between the matrix memory bit pattern and a preset bit pattern of frame characteristic word, generates a coincidence (OC1), or an anti-coincidence decodes signal (OC0). The respective signal is supplied to sync. control (50), which initiates a phase shift in parallel date cycle (PD), whose width contains at least one cycle of the series data cycle (SD). The initiating takes place on simultaneous appearance of the anti-coincidence decoder signal and a clock pulse of a frame cycle (RT), generated to an adjustable frame counter (60). ADVANTAGE - No need for expensive change matrix for synchronisation.

Title: Spinning machine drafting zone - has condenser to approach the output roller pair to counteract unwanted airstream
Inventor: RUMPEL HORST PROF DR ING
IPC: D01H5/12
Filed: 1991-10-04
Abstract: The drafting zone of spinning machine has equipment provided to suppress unwanted air turbulence by means of a condenser before the output rollers. This is formed as partial surface cover around the roller, which has air channel between the beginning of the cover and the point of draft.
