Title: Tumbler pin system with different pin types for cylinder locks
Inventor: KNAUER HELGA
IPC: E05B27/00
Filed: 1994-06-08
Abstract: The tumbler pin system consists of two or more types of cylinder pins (1,2) and their complementary key shaft notches cut to the same angle. Each type of cylinder pin has its own particular angle at the point (6,7) to match the angle of the notch. When matched the pin height (8) will allow the key (9) to be turned. Two or more different angles of notch can be superimposed to form a combined notch (5).

Inventor: HEBING LUDGER DIPL ING
IPC: G01R15/20
Filed: 1994-09-26
Abstract: Measuring devices for determining magnetic fields can be used in particular for the potential-free measurement of the strength of an electric current which generates such a magnetic field. To obviate the need for an intermediate element specially connected into the relevant current conductor and to allow the measurement device instead to be accommodated in a clamp device which needs only to be slipped over the current conductor, the proposed embodiment has two measuring bridges which are fixed on either side of the current conductor; the staggering of the two bridges is assessed from the current magnetic field via a control circuit.

Title: Flow=back protection for bath and shower systems
IPC: E03C1/24
Filed: 1994-11-02
Abstract: The water mixer for the bath is arranged under the upper edge of the fitting. The security against back flow uses a separator with three chambers built in the form of a cartridge, for mounting under the level of the bath rim. A membrane (1) in the discharge valve (2) is influenced by flow-back pressure. The closing force on the valve due to the hydraulic pressure, is opposed by two opening forces, resulting from the reduced hydraulic pressure in the central region (13), and the spring force of the valve. Light control forces result, and no assistance is provided.

Abstract: Lorsqu'on désire, par exemple, effectuer une mesure de pression en utilisant un pont à résistances piézorésistif comme élément détecteur sur une membrane au silicium, le problème consiste à amplifier, tout en maintenant la stabilité en température, la tension différentielle sur la diagonale de sortie du pont à résistances. Pour obtenir, à un coût avantageux, une amplification, stable en température, d'une tension différentielle, un amplificateur (16) est connectable par ses deux entrées (16, 21), par l'intermédiaire, respectivement, d'un commutateur (14, 23), alternativement aux connexions d'entrée (2, 3) alimentées par la tension différentielle (Ud) et à la sortie d'un autre amplificateur (20). L'autre amplificateur (20) est connecté, avec une amplification de 1, par sa propre entrée (28) avec l'une des connexions d'entrée (2) et par son autre entrée (29), avec sa sortie (19). La sortie (30) de l'un (15) des amplificateurs est connectable sous redressement avec régularisation de phase, par l'intermédiaire d'un troisième commutateur (32), alternativement à un condensateur (34) monté en amont d'un étage Darlington (33), et à un potentiel de référence. L'étage Darlington est connecté de son côté, par l'intermédiaire d'une résistance (26), à la sortie (19) de l'autre amplificateur (20) et à la masse; la tension différentielle amplifiée est reçue sur la résistance d'émetteur (39) de l'étage Darlington (33).
