Patent DE-2061594-A1 (DE)
Title: Package winding - traverse mechanism for processing machines giving a constant traverse
IPC: B65H54/38
Filed: 1970-12-15
Abstract: The machines are equipped with constant speed winders i.e., the package is wound against a drum at constant speed. The traversing of the yarn guide is driven separately and as the dia. of the package builds up, the speed of the traverse is adjusted proportionately to maintain the same number of crossings per revolution of the package. This can be done by a rheostat on the arm of the package carrier or by a disc on the package and the motor varied digitally.

Patent DE-2429603-A1 (DE)
Title: Heavy duty friction clutch - has rotatable friction surfaces mechanically engaged by cam operated plunger
Inventor: LINN DONALD F
IPC: F16D13/58
Filed: 1974-06-20
Abstract: The clutch is a fluid-tight assembly connected to an engine flywheel and has a flanged hub carrying a friction disc on its rim, axially movable but non-rotatable w.r.t. the hub. A friction face on the flange is able to contact another face on the flange of a sleeve movable in the hub. These faces are engaged after the friction disc is disengaged from the rotatable clutch assembly. Disengagement is by an axially operating release plunger which pushes against a release lever to separate the friction disc. The sleeve carries a release bearing which is held against rotation along with the second friction surface. The housing shifts axially to move plunger and sleeve and engage the surfaces.
Patent DE-2430679-A1 (DE)
Title: Rear axle trailing arm suspension - with angled arms to alter pivot axis when cornering
Inventor: KRONIGER WILHELM
IPC: B60G21/05
Filed: 1974-06-26
Abstract: The trailing arms of the rear axle are curved towards a mounting block (7) near the middle of the vehicle. A torsional cross bar (6) between two elastic bearings (10) locates the mounting block, as well as bracing straps (2) between the wheels and the torsional bar. For normal suspension movements, with the vehicle travelling in a straight line the trailing axle pivots about a transverse axis (X-X). If the vehicle corners then the reaction forces pivot the outside wheel about an inclined axis (Y-X). This sets the wheel into the corner and reduces tyre drag. The suspension is simple to instal and improves the cornering of the vehicle.

The slider is depressed for simple removal from the spindle or replacement on it. In an alternative construction the nut is divided in the axial direction of the spindle and spring hinged on one side while a pivoted catch is fitted on the opposite side for opening and closing the unit.
