Title: Sync. motor with automatic switch=off - has follower disc rotating and operating switch disc supplying current if switch=off torque between rotor and shaft is exceeded
IPC: H02K11/24
Filed: 1990-03-19
Granted: 1991-06-06
Abstract: The synch. motor with auto-switch-off or disconnection during blocked motor shaft includes stator windings for both directions of rotation, a permanent magnetic rotor with a coupling rotor rigidly seated on the shaft and a follower disc (3) carried by the rotor and movable out from a coupled position when the disconnection torque between the rotor and the shaft is exceeded into a decoupled position in which the torque shunt with the coupling rotor is raised. The follower disc has two diametrically arranged radially extended bearing pins on an extension piece jutting coaxially into the rotor and has two diametrically arranged gaps (30) each provided for two thin parallel radially positioned laminar spring tongues (31) of the follower disc. ADVANTAGE - Eliminates involuntary instant repeat disconnection during reversal of direction of rotation.

Title: Pressure difference measurement transducer - has two electrically conducting diaphragms separated by insulating plate and has strain gauge connected to evaluation circuitry
IPC: G01L19/00
Filed: 1991-09-26
Granted: 1992-10-01
Abstract: The pressure difference measuring transducer has an electrically conducting measurement diaphragm (2) acted upon by a pressure (P1) and a second electrically conducting diaphragm (3), lying beside in the same plane, acted upon by a second pressure (P2). A cover plate (6) of insulating material extends over the first side of the two diaphragms, with conducting layers (7, 8) lying opposite the two diaphragms (2, 3). A second cover plate (31) of insulating material faces the second side of the two diaphragms. A pressure transmission liquid (19) is hydraulically coupled to the diaphragms, such that their position alters opposed to each other, with the occurrence of a difference between the pressures (P1, P2). An electronic evaluation unit (30) is connected with the two layers (7, 8). and the two measurement diaphragms (2, 3) via electrical connections (24; 25; 26), and determines capacitively the position of the diaphragms compared to the layers (7, 8), giving a measurement signal (M3), which is proportional to the pressure difference determined by the pressures (P1, P2). A strain gauge (32; 33) is applied on an outer flat side (31) of one of the cover plates (13), which is also connected to the electronic evaluation unit (30). ADVANTAGE - Influence of static pressure on measurement result is avoided.

Title: Centrifuge for concentrating solids e.g. living cells - has device for adjusting liq. level in 2nd stripping chamber to outer and inner levels provides periodic solids discharge without heat generation
Inventor: BOEKAMP ALOYS
IPC: B04B1/08
Filed: 1992-12-16
Granted: 1994-02-10
Abstract: In a centrifuge drum for concentrating suspended solids, the concentrated solids are passed through channels from an outer solids space of the drum to a radially inward lying first stripping chamber from which it is removed at intervals by a first stripping element, connected to a concentrate line, the separated clear phase being passed from the inner region of the drum into a second stripping chamber and being continuously withdrawn by a second constantly immersed stripping element connected to a clear phase line. The novelty is that a device (15) is provided in the clear phase line (13) for adjusting the liq. level in the second stripping chamber (11) to outer and inner levels, the diameters of the first (7) and second (12) stripping elements being such that, on adjustment to the outer level, the adjusted liq. level in the first stripping chamber (6) lies radially outwardly of the diameter of the first stripping element (7) and, on adjustment to the inner level, this first chamber liq. level lies radially inwardly of the diameter of the first stripping element. Pref., the liq. level adjusting device (15) is a choke element (14) which consists of a pressure regulating device with at least two presettable pressure values. The choke element (14) is connected to a control device (17). USE/ADVANTAGE - Used e.g. in biochemistry for concn. of living cells. The centrifuge drum has low control costs for periodically ensuring reliable stoppage of solids discharge and causes no heating of the first stripping element by liq. friction during this phase.

Title: Method for the termination of an automatic braking sequence for motor vehicles
Inventor: STEINER MANFRED DIPL ING
IPC: B60W30/00
Filed: 1993-11-08
Granted: 1995-03-16
Abstract: The invention relates to a method for the termination of an automatic braking sequence. The object of the invention is to improve an automatic braking sequence in such a way that the braking sequence is always reliably terminated. The intention is to create further termination criteria for the automatic braking sequence which are independent of the brake pedal operating force. According to the invention variables of the vehicle dynamics are used as termination criterion, or the duration of the automatic braking sequence, where necessary also as a function of variables of the vehicle dynamics. This enables the automatic braking sequence to be terminated as a function of the behaviour of the vehicle. In addition it is proposed when terminating the automatic braking sequence to determine the brake pressure gradients as a function of the duration and/or as a function of shut-off criteria.
