Title: Pressure chamber roller seal - has a membrane with coolant and lubricant feeds to reduce friction
Inventor: GORODISSKIJ LEONID GRIGORJEVIT
IPC: F16J15/16
Filed: 1978-01-23

Title: Optical pulses incidence angle measurement - involves monitoring signals from four detectors and two highest voltage signals are used for calculation
Inventor: FIBISCH WOLFGANG DR ING
IPC: G01S3/783
Filed: 1978-07-10
Abstract: The angle of incidence is measured relative to a fixed or movable reference line, esp. the central line of an armoured vehicle. At least four pulse detectors are used, spaced by 90P in a horizontal plane and connected to display device.
