Patent DE-2751831-A1 (DE)
Inventor: HAERING ROLAND ERNST
IPC: H03K/
Filed: 1977-11-19
Abstract: To circumvent the compromise in the equalizer design normally made in the case of known PCM intermediate amplifiers, the equalizer is divided into two part-equalizers. At the output of the first part-equalizer (3), with a flat extent of the edge of the Nyquist low-pass function, the circuits for level control (8) and for recovering the line clock signal (9) are connected, whilst at the output of the second part-equalizer (4), which produces a steep variation in this edge, the decision circuit (5) and, in series therewith, the output circuit (6) are connected. This results in good level control and clock recovery and, at the same time, a narrow noise bandwidth. <IMAGE>

Title: Dosage scale measuring bulk material - uses piston-driven sieve and material guide at end of conveyor belt
Inventor: ERBACHER JOSEF DIPL KFM
IPC: G01G13/00
Filed: 1978-09-22
Abstract: The dosage scale is used to measure out bulk material quantities. A rotatable blocking unit brings the sieve and the sheet metal guide in to contact with the drive end of the conveyor belt. The belt is started and the sieved material falls through the sieve into a weighing vessel.

Patent DE-2854578-A1 (DE)
Inventor: BAUER KARL DR ING
IPC: D02G1/08
Filed: 1978-12-18
Abstract: A method and apparatus is provided for producing a synthetic multifilament yarn having appearance, bulk and hand characteristics of conventional spun yarns of staple fibers while retaining strength characteristics of continuous filament yarns. The multifilament yarn is air jet textured to form loops, bows, coils and the like in at least the surface filaments thereof and at least some of these loops, bows, coils and the like only in the surface filaments are parted while the interior or core filaments remain substantially intact to form a yarn having free filament or fiber ends projecting from a substantially continuous filament core. The interior or core filaments are shielded or protected from being parted by false twisting the yarn (without heat setting the twist therein) to provide a substantially closed form with the interior or core filaments surrounded by the surface filaments and by parting the surface filaments while the yarn has twist therein. Also, other steps are taken and means are provided for limiting the filament parting action solely to the surface filaments. Finally, the yarn is heat set after the filaments are parted and after the twist is removed to fix the characteristics imparted in the previous processing steps therein.
