Title: Automatic transfer of green mouldings to kiln loading station - mouldings transported from final drying station without use of pallets
Inventor: WEBER EDGAR
IPC: B65G49/08
Filed: 1973-07-03
Abstract: After slicing green briquettes into suitable sizes, a number are transferred to an intermediate short belt conveyor which straddles the main transport conveyor. When sufficient mouldings are accumulated on the intermediate conveyor, as indicated by a limit sensor, the conveyor is lowered and the briquettes transferred to the main conveyor. The group is then transferred to the loading station, where a lifting mechanism collects and transfers the group to a pre-determined location in the kiln charge wagon, while this takes place a new group is acquired by the intermediate conveyor.

Title: Recording medium with grooves of different profiles - for recording and reproduction of electrical oscillatory phenomena
Inventor: RABE ERICH
IPC: G11B5/48
Filed: 1974-05-17
Abstract: The surface of the disc is divided into two zones which have differently profiled grooves, so that the inner zone can contain a coarse groove and the outer zone, which can be magnetisable can contain a fine groove. These grooves must, however, have the same pitch and, therefore, permit parallel guidance. The coarse guide will absorb the forces and the fine guide will balance out small variations, especially variations in the surroundings, such as temp. changes and eccentricities. The disc can consist of varying material, so that the inner zone is made of hard material and the outer zone of soft material.
