Interferometrically Controlled Hydraulic Wavelength Drive*

Journal of the Optical Society of America, 1961
After a discussion of the nature and history of the wavelength drive problem, the construction and operation of an interferometrically controlled hydraulic wavelength drive is described. With servo control, the interferometer end reflector which is maintained in contact with the driven element is advanced linearly to within 0.1 fringe. The speed of the

ENERGY SAVING IN HYDRAULIC DRIVES

COLLECTION OF SCIENTIFIC PAPERS
The article discusses various ways to save energy in the hydraulic drive. To do this, you need to study various methods energy saving, including throttling, changes in working volumes pumps and motors, the use of an adjustable pump and throttle flow regulator, as well as study methods of energy recovery in hydraulic drives.
