Patent DE-2819871-A1 (DE)
Inventor: BAUMANN GERHARD
IPC: A01G31/00
Filed: 1978-05-05
Abstract: A nutrient solution containing ion-exchanger plant food is additioned with a mixture of this ion-exchanger plant food and calcium sulphate.

Title: Fixture for machining saw blade teeth - has transverse reciprocating slide with rotating cutter ensuring smooth cutting (PT 24.7.79)
Inventor: BECK ERNST ING GRAD
IPC: B23D63/12
Filed: 1978-07-04
Abstract: The fixture is used for longitudinal machining of teeth on saw blades. A reciprocating transverse slide moves across the longitudinal direction of the saw teeth.
