Patent DE-3111201-A1 (DE)
Title: Tripping device, which is free of auxiliary energy, in switching installations
Inventor: MOOZ DIETRICH DIPL ING
IPC: H02H7/22
Filed: 1981-03-21
Abstract: The invention relates to a tripping device in medium-voltage switching installations. The object is to develop a device which responds to overcurrents without any auxiliary energy and which, in the event of overcurrent, is admittedly intended to take the tripping energy from the circuit which is to be protected and is carrying the overcurrent, but requires no aids for this purpose between the current path to be protected and the tripping device. The solution essentially comprises a pick-up coil which has a short iron core and is arranged in the vicinity of the main current path, but at least at an insulating distance from it, samples the magnetic field produced in the event of an overcurrent and, at the same time, the low induced voltage acts on a tripping element which causes tripping in order to cut the switch off or to signal the overcurrent.

Title: Method for producing a hybrid circuit
Inventor: HALTENORTH HELMUT DR
IPC: H05K1/09
Filed: 1981-08-31
Abstract: A method for producing a hybrid circuit having conductor tracks (F1) which are fitted to a substrate (Su), are in each case located between two contact spots (KF1, KF2) and represent fragments of turns of a magnet coil, and having a magnet core which is placed on these fragments (F1) and has an inner hole such that its magnetic lines of force which enclose the inner hole in operation always run largely parallel to the substrate surface. The remainder of the turns is in each case formed by sections (A) of conductor tracks which are placed over the magnet core and are fitted on a carrier (IF) as a metal layer. These sections (A) of the conductor tracks are conductively connected at their one end to a respectively associated first contact spot (KF1) and at their other end to a respectively associated second contact spot (KF2). The production is particularly simplified in that the magnetic core is initially covered with the insulation which adheres to it, at least wherever the sections (A) are located above it and wherever it is intended to be placed on the fragments (F1), firstly both on one side (underneath) and on the opposite side (top), the magnet core, which is now insulated, only subsequently being placed with its insulation on the fragments (F1) or on the segments (A). The magnet core can additionally be wound, for example in the form of a spiral, to form a magnet ring. <IMAGE>

Title: Three-point suspension device for tractors
Inventor: CONRAD ERNST
IPC: A01B59/041
Filed: 1981-12-24
Abstract: In a three-point suspension device for tractors, composed of an upper link and two lower links which can be raised by a power lifter via lifting rods and can be locked in their lateral setting by swivel plates which rest against them and lockable contact plates, the object is to be achieved of designing the three-point suspension device for tractors in such a way that on the one hand deformation of the lower links is reliably avoided and on the other hand an easy changeover facility can be obtained. The invention achieves this object in that a bar is attached on the side of the lower link facing the contact plate, the one end of which bar is connected via a joint and the other end of which is connected via a support device to the lower link. In this arrangement of a bar, the forces are distributed from the contact plates between two points on the lower link which lie far apart. As a result, deformations of the lower link are reliably avoided.
