Title: Power circuit-breaker
Inventor: HOEGL VITUS
IPC: H01H3/30
Filed: 1994-05-27
Abstract: The circuit breaker has a fuse protection with a high power melt fuse and switches off all terminals of the switch chambers in response to a signal fuse. A switch rod (38) acts simultaneously on all switch chambers. In operation, this is held under the tension of a switch off energy store, which forms part of the drive mechanism, and it is locked in the switch on position by a locking mechanism (54). The latter is unlocked in response to one of the melt fuses. A responsive trigger element is provided for each melt fuse. This triggers a retarding device (56) by its movement which causes a trigger pulse. The retarding device (56) extends the response time of the circuit breaker (4) between the pulse output of the trigger element and the contact separation by a desired time. The retarding device (56) is associated with at least one of the driven parts (28) of the locking mechanism (54). The movement of the driven part is braked at least in the path between the locking position and a position corresponding to the trigger position of the locking mechanism (54).

Patent DE-4435163-A1 (DE)
Inventor: FLIK GOTTFRIED DR
IPC: F02M61/18
Filed: 1994-09-30
Abstract: The nozzle plate proposed is characterized by a longitudinal passage for a fluid, in particular fuel, the passage comprising, in the direction of flow, a filter (42), an annular chamber (47) and a continuous annular gap (35). This design enables a cohesive, tulip-shaped lamellar jet (31) to be produced which thins out in the direction of flow and then disintegrates into very small droplets. As a result, the exhaust-gas emissions of an internal-combustion engine can be reduced, as well as the fuel consumption. The nozzle plate proposed is particularly suitable for use in the valves of fuel-injection systems in mixture-compression internal-combustion engines with externally applied ignition.

Title: Sensor for measuring a motional parameter, in particular crash sensor for a motor vehicle
Inventor: HUBER ANTON
IPC: G01P15/00
Filed: 1989-03-30
Abstract: A sensor for measuring the motional parameter of an object in the event of an accident includes a support (H), by which it is attached to the object, a sensor element (M/K/C), which emits an electrical sensor signal in the event of a relevant motion to be measured, and a seismic mass (M), which is swung into a different position in the event of a motion to be measured and in the test case and which in its movement mechanically touches or moves the electric contact (C) of an electric current switch, thereby actuating said switch (C); said sensor also includes a body (F, K), containing ferromagnetic material and an electromagnet (E) with an air gap, which, when it is activated with test current pulses (I) of predetermined strength and flow, attracts the body over the air gap, the electromagnet (E) and body being of such dimensions that the test current pulse, by attracting the body (K), simulates the motional parameter to be measured, even when the support is unmoved through lack of external mechanical influence, because the magnetic field created by the electromagnet under the effect of the test current pulse moves the seismic mass in the air gap of the electromagnet as far or even further than the position which actuates the current switch that emits the test sensor signal. The seismic mass according to said invention is a cylinder (M) which, when the sensor is not in operation, is held in its resting position by means of a volute spring (F). The body is identical to the cylinder and/or is a part (F) attached to the cylinder, and the cylinder can be pulled directly into the air gap by means of the test current pulse.

Abstract: Beim Verfahren zur Ausrichtung eines Elektronenstrahles relativ zzu einem eine Nutzgravur aufweisenden Bezugsobjekt, das als eine im wesentlichen zylindrisch gestaltete Walze ausgebildet ist, wird die Walze zunächst in Umfangsrichtung durch eine Elektronenstrahlbeaufschlagung mit einer eine Referenzmarkierung ausbildenden Reihe von Ausnehmungen versehen. Anschließend wird relativ zur Referenzmarkierung exakt positioniert mindestens ein Teil der Nutzgravur erzeugt. Nach einer Unterbrechung der Elektronenstrahlbeaufschlagung wird die Referenzmarkierung während eines Meßbetriebes vom Elektronenstrahl durch Abtastung in Längsrichtung der Walze detektiert und anschließend durch Abtastung der Umfangsrichtung der Walze ein Referenzpunkt aufgefunden. Die die Referenzmarkierung ausbildenden Ausnehmungen werden in einem sich lediglich über einen Teil des Umfanges der Walze erstreckenden Umfangsbereiches angeordnet. Nach Auffinden der Positionierung der Referenzmarkierung in Längsrichtung der Walze wird während mehrerer Meßzyklen jeweils innerhalb eines Meßfensters vorgebbarer Dauer eine Positionsanalyse durch die relative Auswertung von aufeinanderfolgenden Meßzyklen zugeordneten Meßsignalamplituden durchgeführt.
Patent WO-9308379-A1 (WO)
Inventor: MUELLER MARTIN
IPC: F01L1/344
Filed: 1992-09-04
Abstract: The invention concerns a hydraulic control device for turning the camshaft (10) of an internal-combustion engine. A sprocket wheel (12) driven by the engine is linked, by means of a linkage element (19) and helical gearing (18) plus straight-tooth bevels (21), with the camshaft (10). Translational motion of the linkage element produces relative rotational motion between the drive sprocket (12) and the camshaft (10). The translation motion of the linkage element is produced by a hydraulic piston (25) acted on by a radial-piston pump (39, 40) which is located in the control device and which aspirates hydraulic fluid out of a reservoir located in the engine and feeds it through outlet valves (47) to the pressure spaces (29, 30) each side of the hydraulic piston (25). Connected to one of these pressure spaces (29) is an electromagnetically operated pressure-control valve (70) which is opened by appropriate actuation of the electromagnet (76), thus decreasing the pressure in the pressure space (29) in front of the hydraulic piston (25). The control device described, which is extremely compact in design, is illustrated in the figure 1.
