Title: Optical network for transmitting sensor data
Inventor: HEYWANG WALTER PROF DR RER NAT
IPC: H04B10/00
Filed: 1981-07-10
Abstract: Measurement values can be transmitted via optical waveguides in a range of applications. These include, for example, the production and process control in industry, military technology, for example with respect to vehicles and missiles, and traffic engineering, for example in the control of engines. The basic object is to create an optical network for transmitting sensor data which utilises the known advantages of the application of optical waveguides and is designed in such a manner that it is universally suitable for scanning and transmitting different measurement quantities. This object is achieved by an optical network comprising modules consisting of sensors of various types which, due to the action of a measurement quantity, emit an electrical signal which is supplied to the control input of an electro-optical light modulator which thereupon converts the unmodulated light power supplied to it into modulated light power, the percentage of modulation representing the measurement quantity acting on it. <IMAGE>

Title: Pressure intensifier for sealing-liquid systems of mechanical seals
Inventor: BACH MEINHARD
IPC: F16J15/40
Filed: 1982-07-21
Abstract: The known pressure intensifiers for sealing-liquid systems of mechanical seals, which operate with stepped pistons, have the disadvantage of an additional outlay on maintenance and the risk of faults due to the wear of the various seals necessary here. The invention proposes a pressure intensifier which likewise operates on the principle of differential surfaces but manages without the fault-susceptible piston-cylinder system and without seals on moving parts. The pressure intensifier according to the invention is formed by a pressure vessel, the volume of which is divided into two gas-tight spaces by two flexible metal bellows of different diameters, the smaller-diameter bellows provided with a concentric guide and with its interior connected to the atmosphere being arranged in such a way as to allow displacement within the larger-diameter bellows, which is sealed off relative to it and can be pressurised from inside by the pressure medium, while the pressure vessel space surrounding the bellows communicates with the sealing chamber of the mechanical seal.
