Title: Electric cable with polyethylene type insulation - and outer conductive layer contg. release agents e.g. silicone or polyethylene glycol! cpds.
Inventor: IVANFY BARTHOLOMEUS DIPL ING
IPC: H01B9/02
Filed: 1977-05-21
Abstract: An electric cable comprises an insulation of opt. cross-linked polyethylene or ethylene co- or terpolymer and an outer conductive layer co-extruded and opt. co-vulcanised with the insulating layer. The conductive layer is of polyethylene, chloroprene rubber, chlorinated polyethylene, SB and/or natural rubber contg. conductive lamp black. The improvement consists in incorporating release agents in the conductive layer comprising silicones, polyols, ethers, aldehydes, waxy aliphatic hydrocarbon and/or higher liq. aromatic hydrocarbons. Good adhesion between the layers is ensured and, therefore, good electrical rigidity, while, on the other hand, the external conductive layer can be easily removed from the insulation without damaging the latter. The silicones are pref. silicone oil, grease, resin or rubber. The polyols have mol. wt. >=500 and are pref. polyethylene-glycols. The ethers have b.pts. >=200 degrees C and are pref. dibenzylethers and/or their derivs. The aldehydes influence the peroxidic crosslinking speed and are pref. tetra hydrobenzaldehyde. The waxy aliphatic hydrocarbons are paraffin oil, wax or polyethylene wax.

Title: Loading conveyor discharge height adjustment - has sensors to measure vertical and horizontal distances to load and container walls
Inventor: DROESCHLER ULRICH DIPL PHYS
IPC: A01D33/10
Filed: 1977-08-22
Abstract: The system continuously adjusts the discharge height of a conveyor loading a container movable in relation to it, e.g. when delivering potatoes into trailer travelling alongside the harvesting machine. The distance between the discharge end and the surface of the load is continuously measured by a contactless device, typically ultrasonically, and the end is raised or lowered where this distance deviates from the desired value. The distance to the surface of the load (12) accumulating in the trailer (2) is measured vertically at the outer edges of the conveyor (3), and simultaneously a horizontal measurement is made to any item with which the conveyor may collide, such as the trailer wall. The first deviation from the desired vertical or horizontal distance which is detected causes the conveyor to be raised or lowered.

Title: Ring traveller monitor - is operated by a remote control to keep it at ring rail height
Inventor: DERICHS JOSEF DR ING
IPC: D01H13/14
Filed: 1977-12-24
Abstract: The mechanism to monitor the movement of the ring traveller on a ring spinning or twisting machine uses a sensor which is non-mechanically coupled to the ring rail. There is a remote controlled adjuster to vary the height of the sensor.
