Patent EP-0002935-A2 (EP)
Inventor: BRAUKMANN HEINZ WERNER
IPC: F16K17/08
Filed: 1978-12-20
Abstract: A differential pressure relief valve has a housing with first and second chambers sealed from the atmosphere and separated by an annular diaphragm, with the chambers and the diaphragm being traversed by a sleeve movable with the diaphragm. The first chamber communicates with a primary pressure source through a first channel in the valve housing, and the second chamber communicates with a secondary pressure source through holes provided in the sleeve and through a second channel in the housing. The end of the sleeve remote from the second channel extends from the second chamber to seal with a valve seat. When the primary pressure exceeds the secondary pressure by a predetermined amount, the lower end of the sleeve engages the valve seat. When the primary pressure does not exceed the secondary pressure by the predetermined amount, the lower end of the sleeve does not engage the valve seat, and fluid escapes from the second conduit through the second channel and the sleeve past the valve seat until the differential pressure rises to the predetermined amount.

Abstract: This invention concerns a so-called double-moat uni- surface type semiconductor device in which two concentric moats (9,10) are provided in one main surface of the substrate and the edges of the two pn-junctions (J I ,J 2 ) for blocking main circuit voltages applied to the device are exposed in the surfaces of the moats. The moats are filled with surface passivating material (11,12). In order to increase the voltage withstood by the device, irrespective of whether negative or positive charges are induced atthe interface of the semiconductor substrate and the passivating material, semiconductor layers (6,7,8) having high impurity concentrations and serving as channel stoppers are formed in the semiconductor layers exposed at the one main surface of the substrate, contiguous to the moats and spaced from the pn-junctions. Each such high impurity concentration layer (6,7,8) has the same conductivity type as the semiconductor layer in which it is formed.

Abstract: A non-dispersive infrared gas analyzer, in which infrared energy is directed through a sample cell (11), and is interrupted at a predetermined frequency. The infrared energy at least one preselected wavelength is detected to produce an AC signal having an amplitude proportional to the infrared energy passing through said sample cell and having a frequency corresponding to the predetermined frequency. The preselected wavelength corresponds to the characteristic absorption wavelength of a preselected gas. This AC signal is processed to produce a DC signal having an amplitude proportional to the concentration of the preselected gas in the mixture being analyzed. The signal processor (Fig. 2) includes an output amplifier (15), a voltage biasing network including a summing junction (21) connected to the input of the amplifier (15), and a first variable control (17) manually adjustable to bring the current at the summing junction to zero in the presence of a non-absorbing gas in the sample cell.
