Title: Combined lathe and milling machine - roughs out keyway with back tapered end-mill and finishes sides by traversing with work slightly rotated
Inventor: WINGENBACH WILLI
IPC: B23B3/06
Filed: 1990-04-14

Patent DE-4012205-A1 (DE)
Inventor: MAHMUD SHABAZ
IPC: H04N5/95
Filed: 1990-04-14
Abstract: During the processing of video signals, a signal flow fluctuating with time must be expected from certain signal sources such as, for example, in the case of a video recorder. However, the process of writing into a frame buffer is carried out with a crystal-controlled clock. For this reason, the incoming video signal which has signal flow fluctuations, must be conditioned in an interface to the frame buffer in such a manner that during the process of writing-in with a stable clock, an error-free storage of the video signal in the frame buffer is ensured. The interface according to the invention enables the video signal to be stored without errors. It consists of a buffer store which is arranged between the analog/digital converter of the processing unit and the frame buffer, this buffer store being driven by a control device which consists of an input controller, an output controller and an address comparator. The control circuit is designed in such a manner that data are temporarily stored when the data flow of the analog/digital converter is faster than the data flow into the frame buffer and that the output to the frame buffer is stopped when the data flow in the analog/digital converter is slower than the data flow into the frame buffer. <IMAGE>

Patent DE-4021545-A1 (DE)
Inventor: EIFLAENDER INGO
IPC: D01D5/088
Filed: 1990-07-06
Abstract: The invention relates to a process for making synthetic threads or fully oriented filament yarn from polymers via the molten spinning of microfilaments which are cooled at least to solidification temperature behind a spinning nozzle and then heated for drawing purposes to a temperature above the melting point and at the same time blown with air to produce the necessary tension. Microfilaments having a single titer of less than 1.0 dtex are fed unbunched through the heating region and air is blown on them in counter-flow. It is thus possible fully to orient the microfilaments and obtain the synthetic threads thus formed at a relatively high drawing rate and with a short heating region. The synthetic threads have a relatively small expansion and may be used immediately, meaning that, owing to the fineness of the threads, it is possible, without further processing, to make particularly fine, smooth and silky textiles.

Title: Multi cross-wound bobbin winder - has system of rails with joining bridge rails to give low deceleration and acceleration at direction changeover zones
Inventor: SCHIPPERS HEINZ DR
IPC: B65H54/28
Filed: 1991-08-30
Abstract: The movement of the reciprocating yarn guide system, to feed a number of yarns for cross winding to a number of bobbins clamped coaxially on a spindle, has two pairs of rails for the straight guide path which extend over the working length, parallel to the spindle axis. The rails intersect in each of the path gaps between two stroke lengths. A number of reciprocating yarn guides ride in each pair of rails, with the same direction of movement. The rail sections facing each other, from both pairs, are close together along the stroke length, parallel to the spindle axis, and form a passage for the reciprocating yarn guide driven by the spirals of the drive roller as working rails, linked to bridging rails at their ends to the next stroke length. Outside the working length, the rails of each pair are joined together by deflection points at a change-over zone and, at the reverse movement, all the guides follow the same direction. The guide is driven along the pair of rails through a groove in the spiral grooved roller to advance and reverse the yarn guide over the working length. ADVANTAGE - The yarn guide life is extended as there are low deceleration and acceleration forces applied at the change-over zones.
