Title: Method and apparatus for the electrostatic flocking of material having an endless or yarn configuration
IPC: D02G3/40

Granted: 1989-05-10
Abstract: A method and apparatus for electrostatically flocking a thread-like or yarn-like material. This material rectilinearly and continuously or intermittently is moved through an electrical field which is generated between electrodes having non-planar yet symmetrical potential surfaces. This electrical field preferably is generated between curved potential surfaces of the electrodes. The flock is shot into the adhesive coating of a given thread not only radially but also at an angle. The thread does not have to be turned. As a result, a dense and improved flocking is achieved all around the yarn or thread in a simple and economical manner.

Abstract: A ring communications network has a plurality of terminals coupled together to provide a unidirectional communications ring, each terminal being arranged to receive a first digital signal at a data rate associated with the next upstream terminal in the ring and to transmit a second digital signal at a transmit data rate which may be different from the data rate of the received signal. Each signal comprises data packets interleaved with synchronization packets of elastic length to achieve synchronization around the ring. Thus, each terminal has a synchronizing network (12) containing an electric clock generator (32) having a plurality of outputs each shifted in time by a different multiple of 1/8 times the period of a fixed transmit clock signal generated internally by a transmit clock generator (26). In effect, synchronization is achieved by a shallow discretely adjusted delay (FIFO) buffer and sample point readjustment network. The buffer is read at the fixed transmit data rate and loaded at that same rate until the period of elasticity is detected. Then the sample point is reselected to fall in the middle of a transmit bit window effectively changing the FIFO buffer depth.

The transformation is carried out at a temperature between 20 and 200°C under reduced pressure over a duration of between 1 and 100 hours in an atmosphere inert to the precursor polymer (V) film and to the poly(acetylene) (III). Poly(acetylenes) are conducting polymers and find use in solid state batteries, field effect transistors and the like.
