Title: Stable garlic powder - produced by deep freezing
IPC: A23L27/16
Filed: 1971-01-15
Abstract: Undamaged garlic bulbs are deep-frozen (pref. to -30 degrees C), ground in the frozen state, and freeze-dried.

Title: Evaluation of ground direction finding data - for aeronautical rotating radio beacon involves direct 3OHz vibration and sub-carrier vibration
Inventor: FIEDLER GUENTER
IPC: G01S1/02
