Title: Ring spinning frame holding cop plates securely - has transport system to and from winders to carry cop plates with tubes or cops
Inventor: WERNLI JOERG
IPC: D01H9/18
Filed: 1991-04-22
Abstract: A yarn transport system between a ring spinning frame and winders has a vertical conveyor band surrounding the frame. As the band revolves at the frame end, the empty tubes held on top plates are directed up against a device, placed at intervals along the band. This has the shape of a long and short finger, pressing the cop plate along a horizontal surface with a boundary edge. The cop plates with empty tubes travel along the sides of the frame. When tubes have been exchanged for full cops, the finger device carries them to an exit position, to connect with a conveyor to the winders. ADVANTAGE - The mechanical arrangement holds the cop plates securely, and these can be aligned accurately in the spinning position.

Inventor: TROESTL ALFRED
IPC: H05K9/00
Filed: 1992-03-31
Abstract: In electronic ballasts for gas discharge lamps (3) which consist of a bridge rectifier (1) to be connected to the a.c. mains and a converter (2) connected downstream thereof, the brightness of the lamp may flicker, which is particularly annoying with the lamp (3) dimmed. To prevent this flicker, it is opposed that the operating potential terminal (mass) (6) inside the circuit be connected in the a.c. manner to the protective earth (S) of the a.c. mains. A second method may consist in connecting the internal reference potential terminal (mass) (6) to the phase terminal (L) and/or the neutral terminal (N) or with one or both of input terminals (10, 11) of the bridge rectifier (1) in the a.c. manner. In a third method, the a.c. "hot" output terminal of the bridge rectifier (1), which is connected to the internal reference potential terminal (mass) (6) via a smoothing capacitor (C4), is to be connected in the a.c. manner to the protective earth (S) of the a.c. mains. Yet another method is to screen the lines (15-18) leading to the lamp (3) and to connect the screens (15, 16, 17, 18) to the circuit-internal reference potential terminal (mass) (6).
