Title: Sieve band press for dewatering slurries - with pressure rollers alternating between pressing and relaxation positions
Inventor: OELBERMANN MAX DIPL ING
IPC: B30B9/24
Filed: 1978-05-29
Abstract: Sieve band press for dewater slurries has a press zone contg. two sieve bands (carried on permeable support bands) which enclose the slurry. The bands pass between a gp. of stationary support rollers and a gp. of mobile press rollers, the latter being driven to and fro relative to the support rollers. The new feature is that the pressure rollers move between (a) a high pressure pressing position in which the sieve bands are forced into a wavy path, and (b) a release zone in which the waves in the band are reduced or eliminated. This movement is controlled by a programmeable load pattern. The dwell time (TN) of the rollers in the release zone is smaller than that taken (TD) for the bands to pass through the press zone and smaller than the dwell time (TH) of the rollers in the high pressure position. Larger amts. of slurry can be processed per unit time and different types of slurry can be accommodated by adjusting the various dwell times.

Title: Automatic splicer for broken ends on winding frame - transfers threads from above and below into pneumatic chamber
Inventor: ROHNER JOACHIM
IPC: B65H69/06
Filed: 1978-10-16
Abstract: A mechanism including a chamber having a lengthways running groove, which can be covered by a hinged cover, and into which two ends of yarn can be introduced and spliced by means of a lateral jet or compressed air, serves to join a thread from above to a thread from below. The introduction of the broken ends of the thread into the longitudinal groove is effected by a mobile device for drawing the thread which is displaced from a position in which it locates and picks up the thread to one in which it releases it. The threads are introduced into the chamber either, not crossed, and pref. parallel to each other, and are held until the compressed air is delivered, or they may be crossed during the pivoting action of the thread drawing device. The chamber is closed by a cover. The ends of the thread from above and of the thread from below are automatically sheared. Compressed air is blown into the chamber. Used to effect a joint by a splice between an upper and a lower end of yarn, as in a winding frame, whilst eliminating all the influences which depreciate the quality of the joint and depend upon manual skill.
