Title: RF subterranean electrical resistance measuring appts. - has electrical and magnetic field sensors, superheterodyne signal processing and evaluation of amplitude and phases by sample=and=hold system
Inventor: KUHNKE FALKO DR
IPC: G01V3/12
Filed: 1991-10-12

Inventor: RISAK VEITH DIPL ING DR
IPC: G05B23/02
Filed: 1992-02-06
Abstract: The monitoring method involves acquiring and evaluating process parameters in an ordered object (01, 02,..06) of an object oriented database.

Title: Method for fitting electric lamps with caps
Inventor: STRUCK PETER
IPC: H01J5/58
Filed: 1993-02-08
Abstract: The invention relates to a method for fitting electric lamps with caps, in which the cap sleeves (2) are cemented to the lamp bulbs (1). Before the cap sleeves (2) are fitted on the lamp bulbs (1), there is applied to the cap sleeves (2) which are coated with cement (4) an electromagnetic radio-frequency signal which heats and pre-dries the cement (4). This drying process prevents the cement (4) from sagging into the base (5) of the cap sleeve (2) and permits further processing of the cap sleeve (2), coated with cement (4), as storable bulk materials in a modern high-performance production line for electric lamps. <IMAGE>

Title: Gate valve and method for its production
IPC: F16K3/18
Filed: 1993-03-26
Abstract: In the present invention, a description is given of a gate valve which does not allow any constituents of the media to penetrate into the housing space during the change from the open to the closed position or vice versa. This is achieved by virtue of the fact that the shut-off element is provided at the sealing surfaces with thin layers of sheet metal which are welded to one another in a pressure-tight manner. The two pressure spaces formed can be subjected to an internal pressure corresponding to the service pressure and to the necessary elastic deformation of the sheet-metal layers. The differing pressurisation of these two spaces is performed by a control capable of detecting pressure differences in the closed position of the fitting. <IMAGE>
