Title: Synthetic monofilament yarn drawing - has take=off unit working at higher speed than feed to apply heat shrinkage and hold yarn at constant length before take=off
Inventor: GREIFENEDER KARL DIPL ING
IPC: D02J1/22
Filed: 1991-03-04
Abstract: In drawing synthetic monofilament yarns, the yarn is fed continuously at a given speed through a feed unit, and then taken continuously from a take-off unit at a higher speed. The yarn is allowed to shrink on the take-off unit, where it is held at a constant length for at least one preset time span. Pref. the yarn is held at a constant length, immediately after shrinking, for a time span of 0.002-4.0 sec.At the take-off unit, the yarn is heated to a temp. above the glazing temp. of its material, pref. 120-250 deg. C., through contact heat with the take-off unit. The yarn is shrunk in a first stage, and then held at a constant length in a second stage, with repetition of the first and second stages a number of times, pref. two to four times. Each of the two stages lasts 0.01-2.0 sec. Before the yarn is taken through the take-off unit, it passes round a pin, pref. an unheated pin with a dia. of less than 10mm, at an angle of 180-360 deg. round the pin. Before and/or after the take-off unit, the yarn is wetted with a fluid, pref. a watery fluid. While the yarn is held at a constant length, its tension is held at 0.05-2.5 cN/dtex for the preset time span. ADVANTAGE - Directly after it leaves the take-off unit, the yarn has a low residual shrinkaf

Title: Suspension water extraction - uses two continuous filter belts with material between them to be carried past vibrating suction units on elastic mountings
Inventor: TRUEMPER-BOEDEMANN EHRHARD
IPC: B01D33/03
Filed: 1993-03-01
Abstract: In the assembly to remove water from a suspension, where the filter is a continuous conveyor belt, a suction box is used on an elastic mounting, fitted with a vibrator. Pref. the material to be processed is carried between two filter belts through one or more suction units, with two suction units facing each other. The belts are continuous, passing round deflection rollers at their ends. The vibration drive is synchronised for the facing suction units. The working plane of the vibration drives can be varied at the suction units, and the vibration frequency can be different at the separate suction units. The underpressure in the separate suction units can be brought to zero, at intervals or permanently, or changed to an overpressure. The two filter belts travel at different speeds. The centre verticals of two facing suction units can be different, for two facing suction units, at the filtered matter. USE/ADVANTAGE - The system is used for the extraction of water from a mixture of liquid and solid matter, such as in cardboard mfg. The vibrating suction unit improves the water extraction rate, to leave a consistent layer of filtered material
