Patent DE-19700111-A1 (DE)
Inventor: WIRTH HARRY
IPC: E06B9/28
Filed: 1997-01-03
Abstract: The invention relates to a device for protection against the sun of Venetian blind type with a plurality of parallel lamellae with horizontal longitudinal axes, which pivot around their longitudinal axes by means of a regulating mechanism. The device is characterized in that these lamellae, or a coating applied to the upper surface of the lamellae, consist of translucent material, and have a cross section perpendicular to the longitudinal axis of the lamellae. This cross section consists of a) first flat sections which are arranged obliquely to the upper surface of the lamellae and receive the sun's rays approximately perpendicular, b) second flat sections which are flush mounted, at an acute angle of approximately 45 DEG  to the first flat sections, and c) a third flat section which is approximately perpendicular to the second flat sections, in such a way that adjacent first and second flat section pairs are separated by a distance, thus enabling a shadow-free irradiation and reradiation over the first sections, when the sun's rays hit the first sections in approximately perpendicular fashion. This distance makes it possible to dispense with all connectors, or to fit visual connectors, of which one upper surface coincides with the upper surface of the lamellae, and another upper surface lies parallel to the third side or coincides with it.

Title: Method for non=destructive determination by X-ray diffraction of expansion free grating parameters and/or mechanical stress conditions
Inventor: KAEMPFE ANDREAS
IPC: G01N23/20
Filed: 1997-05-07
Abstract: The method involves the separate determination of the depth distributions of the expansion free grating and stress conditions using the whole diffraction spectrum. To determine the depth profile the Bragg angle qy*,f* for several diffraction maxima is measured in the expansion free direction with Y*, F* for a plane stress condition given by :- with F* optional,V an elastic constant and s11/s22 ratio of stress components. To determine the stress condition at 1/e-penetration depth T the Bragg angle q for the diffraction maxima of severAl reflections is measured. To each reflection there is allocated a tilt angle Y so that the depth T remains constant during the measurement and the stress condition for the penetration depth is given by :- where:- s1 and s2 are x-ray graphical elastic constants for each reflex (hkl)sij:=stress components. To determine depth profiles of the mechanical stress the stress in various I/e penetration depths t is determined

The regulator (1) is characterized in that the housing (7) has a support surface (19) comprising a passage orifice (30; 46) for the medium flow. When the regulator (1) is mounted, it rests on a counter surface (23; 23') located on the bearing arrangement, the threaded spindle nut or the guide so that a direct medium communication (3; 3') between the regulator (1) and the pocket and/or the medium supply is achieved.
Patent DE-19742655-A1 (DE)
Inventor: GRILL BERNHARD DIPL ING
IPC: H04S1/00
Filed: 1997-09-26
Abstract: A process for coding a time-discrete stereo signal having a first and a second channel (R, L) makes it possible to scale stereo coding. A monosignal (M) is first formed from the stereo signal, then coded, and the coded monosignal is transmitted in a bit stream. Finally, the coded monosignal is decoded again and stereo information is formed on the basis of the coded/decoded monosignal (M') and of the first and second channels (R, L). This stereo information is coded and also written in the bit stream to yield a bit stream with a completely coded monolayer and a layer with coded stereo information.

Title: Metal-ceramic substrate for electrical circuit
Inventor: SCHULZ-HARDER JUERGEN DR ING
IPC: H05K1/03
Filed: 1997-03-01
Abstract: Processes are claimed for producing an electrical circuit substrate by applying first and second metallisations (3, 4) onto both sides of a ceramic layer (2), the first metallisation (3) being a copper foil applied by a DCB (direct copper bond) technique. In one process, a substrate (1b) with a through-contact (10) is produced by providing an opening (11) in the ceramic layer and applying the second metallisation (4) as a metal-containing paste by a thick film or thin film technique such that the paste is also applied onto the opening (11) and a first metallisation area exposed in the opening. In another process, in which a metallic interlayer is to be formed for thermal and/or electrical connection of the substrate (1a) to another component (e.g. a metal base plate, 6), the second metallisation (4) is much thinner than the first metallisation (3) and is applied as a metal-containing paste by a thick film or thin film technique. Also claimed is a substrate produced by one of the  above processes.

Title: Nondestructive ultrasound testing method for test object with curved surface, e.g. pipe
Inventor: PRAUSE REINHARD DIPL ING
IPC: G01N29/24
Filed: 1998-02-04
Abstract: A reflecting surface (30) is arranged between an ultrasound probe head (20) and a test object (22) and close to the top surface of the test object. The surface (30) is placed outside the centre (24) of the ultrasound beam so that the ultrasound beam hitting it is reflected and enters the test piece at approximately 90 deg . A reflected signal from the test piece can thus be detected. The detector can thus be operated in a mode using a start echo. Advancements to the basic idea include a shoe fitted to the ultrasonic probe with the reflecting surface integral within it and a probe in which the angle of the reflecting surface can be altered so that the probe can be used on surfaces of different curvature.

Patent DE-19828481-A1 (DE)
Title: Pressure accumulator assembly
Inventor: CHANG YU-CHUAN
IPC: F17C5/00
Filed: 1998-06-25
Abstract: The assembly has openings on a valve body for separately installing a detection member and pressure inlet/outlet, and being in communication with the interior of the valve body. A conduit has one end inside the valve body, while the other end extending out of the valve body. The conduit divides each opening inside the valve body so that the assembly openings form separate channels of incomplete communication inside the valve body. Thus when the valve body and the conduit are assembled on a cylinder, the separate channels of the assembly openings are in communication with each other at the bottom of the cylinder thereby achieving gas-liquid separation in the pressure accumulator assembly.
