Patent DE-1942226-A1 (DE)
Title: Laminated light weight concrete panels for building - construction manufactured in a casting mould
Inventor: CARLEN ERIK
IPC: B28B19/00
Filed: 1969-08-19
Abstract: Light sandwich layers, preferably of highly porous plastics, or mineral wool, wood, paper or diatomaceous earth (Kieselgur) are placed into mould with required dimensions and suitably secured at sides of mould or from above. Layers are preferably of cellular or honey-comb-like consistency and arranged at intervals of at least twice the width of the required final layer of lightweight/porous concrete. The cavity between each sandwich layer and both outermost cavities on sides of mould are then filled with the concrete material, which is left to harden to a suitable consistency when it can be cut by wires parallel to sandwich layers, resulting in several sandwich plates obtained from one casting process, each one of which has at least one sandwich-layer forming the core and is covered outside layers of concrete material. After cutting, the separated plates are transported into a suitable hardening vessel for steam-hardening at elevated temperatures and pressure.

Patent DE-2347710-A1 (DE)
Title: Railway automatic shunting system - incorporates motor with switch units to reduce starting torque and impact shocks
Inventor: PREINFALK FRANZ DIPL ING DR
IPC: B61J3/06
Filed: 1973-09-21
Abstract: The movable transporting carriages in the train-forming sidings are driven directly or indirectly by electric motors. Sections forming the train are moved by retractable arms by a pre-determined amount. The carriages return to their original positions, before the next section arrives. The motors have associated switch elements, to limit the motor starting torque, to avoid high collision shocks between carriages and train sections. The level of the limited torque is below the nominal value, determined by the necessary speed of transportation, and is then increased continuously or step-by-step, to the nominal value, to effect only a small acceleration momentum acting onto the train sections.
