Patent DE-2357118-A1 (DE)
Title: Tilting table for moving large panes of glass - esp. insulating panes used for double glazing
Inventor: KIWULL MATTHIAS DIPL ING
IPC: B65G49/06
Filed: 1973-11-15
Abstract: A glass pane is laid horizontally on a table and located against a row of brackets running along one edge; two suction pads retian the pane on the table which is then motor-driven along a track to a position indicated by contact switches on the brackets which stop the motor. A piston rod in a cylinder is then used to swing the table upwards on a pivot underneath the brackets so the pane passes through the vertical position until it is parallel with a stack of panes on an inclined bed. A second motor then lowers the upper part of the table so the pane is exactly in line with the stack and the suction pads are released by a contact switch. The use of the contact switches make the operation automatic. Eliminates the possibility of damage or scratching of the panes during stacking.

Title: Angled sleepers for secure railway track setting - have one or more bends as seen from above in order to lock securely into ballast
Inventor: NEU DIETER W DIPL ING
IPC: E01B3/00
Filed: 1974-01-11
Abstract: The angled sleepers may be made of reinforced concrete, prestressed concrete, steel or other materials. One bend producing a shallow V-shape, is suitable for narrow and standard gauge railways but multiple bends in plan may be more suitable for broad gauge tracks. Such sleepers can draw in the intervening ballast for improved accommodation of transverse forces, and secure rail position-holding under high-speed traffic can be improved. Normal track construction and consolidating machines can be used in maintenance work. The peak of the shallow V may be sharp, but the inside of the V may be gently curved. The ends of the sleepers are shaped so that the end faces are parallel to the rails.

Title: Control circuit for inverter - is fitted with premagnetised current limiting choke in commutation circuit
Inventor: HOSHI TOSHIHIKO DIPL-ING
IPC: H02M7/515
Filed: 1975-06-05
Abstract: In place of the conventional series reactor a premagnetised saturable choke (10) is employed. This may comprise a permanent magnet excited core, or a core with control windings whose current may be made partially dependant on the current flowing in the inverter load (11). The use of a controlled reactor limits the commutating current to a value of sufficient magnitude to just extinguish the main thyristors (3, 4) and thus permits the use of smaller thyristors (7, 8) for the commutating circuit switching duty. A particularly favourable arrangement is produced if the premagnetisation is produced by two windings, one independent of inverter load and the other dependant upon load current.
