Title: Coupling plate for two shaft power take=off - has reversed mounting for plate using recessed bolt holes
Inventor: GARTNER HELFRIED
IPC: A01B71/06
Filed: 1979-08-16
Abstract: The coupling plate is used in a tractor PTO. The plate is bolted to one of two concentric drive shafts (1, 2) by reversing the plate and securing with three bolts. The bolts are shorter than the width of the plate and the correct fitting of the bolts is ensured by mounting in recessed bolt holes. The correct three bolt holes are the recessed ones from each. This ensures that the bolts cannot reach the incorrect shaft, nor can both shafts be locked together by the two sets of bolt holes.

Title: Clarifier sludge pasteurisation - using scraped wall falling film heater with circulating heating medium prior to reactor
Inventor: HUG PETER
IPC: C02F11/18
Filed: 1980-01-23
Abstract: Clarifier sludge is pasteurised in a system consisting of a heat exchanger and a reactor. The heat exchanger is of the falling film type with a cylindrical housing. Inside this is a rotor to which are attached wiper blades. These blades ensure that a thin, agitated film of sludge flows down the walls and is uniformly heated. The outer jacket is heated by means of a circulating heat transfer medium. Used for sterilising clarifier sludge from biological sludge treatment plants before disposal as fertiliser. Conventional shell and tube heaters tend to foul and form encrustations very with this process. The scraped wall device avoids this.

Title: Roller conveyor retarding system - supports roller casing from stationary spindle via pressurised elastic hose
Inventor: LOECHT HEINRICH VAN DE
IPC: B65G13/075

Title: Apparatus for making a yarn
Inventor: FEHRER ERNST DR
IPC: D01H4/16
Filed: 1981-01-10
Abstract: An apparatus for the open-end spinning of a yarn from introduced fibres or for spinning round a yarn core with introduced fibres is described. The apparatus has two suction drums (1) which rotate in the same direction and which form between them a gusset region (5) for the yarn formation or the spinning round of the yarn. In order to stabilise the yarn-forming line, the tangents, lying in a cross-sectional plane, to the circles of rotation of the suction drums (1) are to form an angle ( alpha ) of 8 DEG  to 16 DEG  with the yarn at the points of contact of these drums. For this purpose, it is proposed that the drum diameters each amount to 100 to 200 times the yarn diameter. <IMAGE>
