Title: Digital measurement of tracked vehicle speed - without track magnetisation and demagnetisation uses speed dependent linear motor frequency
Inventor: ECKERT GERHARD
IPC: B61L3/00
Filed: 1975-08-20
Abstract: An arrangement for digital measurement of the speed of tracked vehicles operates without necessitating the magnetisation and demagnetisation of the track. Magnetic systems use a transmitter on the vehicle to magnetise the track and a receiver on the vehicle to scan the magnetised part. To avoid magnetisation and demagnetisation a linear motor is mounted on the vehicle above the track. The motor excitation frequency varies with the vehicle speed, and the motor supply voltage varies with the frequency. To determine the motor operating null point the current in one phase of the motor is measured at periodic intervals and zero-crossing values of the current are used to regulate the excitation frequency.

Title: Formation and reconstruction of linear holograms - using surface holograms in non-destructive material testing based on pulse-echo method
Inventor: KUTZNER JUERGEN DR RER NAT
IPC: G01S15/89
Filed: 1976-11-18
Abstract: An arrangement for the formation and reconstruction of acoustic linear holograms for non-destructive material testing uses the pulse-echo method.
