Patent DE-2147376-A1 (DE)
Title: Aluminium pig-caster with subdivided moulds - produces small pigs accurately
Inventor: SPRINGER KURT
IPC: B22D5/04
Filed: 1971-09-22
Abstract: The moulds on an aluminium pig-casting machine are subdivided along the length into separate compartments by triangular partitions which stretch the full length of one wall and halfway up the adjacent wall. After casting, the mould is tilted so that the metal lies wholly within the individual compartments in which it solidifies, ready for knocking out later on the moving track. A relatively large weight can thus be cast at once, without the necessity for a subsequent mechanical parting operation.

Title: Train speed dependent interference reduction - uses speed dependent signal generation for filter pass characteristic control
Inventor: SCHNEIDER WOLFGANG DR ING
IPC: H04B5/00
Filed: 1975-01-18
Abstract: The communication system for tracked vehicles, reduces the severity of interference that arises as a result of the vehicle speed. A signal is generated in the vehicle that is proportional to the vehicle speed and is used to filter in the vehicle receiver such that noise components dependent on speed are suppressed. The suppression filter can be a comb filter, and especially a transit time chain consisting of a cloked analog shift register whose clock pulse period is inversely proportional to the vehicle speed. The vehicle speed dependent signal may be derived from the Doppler shift of a pilot tone, transmitted outside the useful signal frequency band.
