Title: Friction clutch for motor vehicles - has double roller bearing withdrawal mechanism with integrated guide allowing radial movement
IPC: F16C35/067
Filed: 1975-02-07
Abstract: The clutch withdrawal bearing has two concentric roller bearings with a separate cage. This is integrated into a guide (14) connected to the clutch components.

Title: Automatic control for timber drying kiln - uses graded programme with steps commanded by changes in continuous moisture measurement
Inventor: ROEDER HEINZ
IPC: F26B25/22
Filed: 1975-05-27
Abstract: Known methods of controlling the atmosphere in a timber-drying kiln are based either on measurements of loss of weight of the contents, on previous experience or on an electrical measurement of the moisture content combined with observations of the reaction of small test specimens to the kiln atmosphere. The present proposal is for a graded programme which is only allowed to proceed to the next stage when continuous measurements, made electrically, reveal a fall in the moisture content of the timber. Test specimens are not used. The comparison of measured with programmed value will also be made electrically, so that the drying program can be self-regulating.
