Title: Pressure relief valve for fluid medium releases fluid for return to lower
Inventor: BOLLMANN HENNING
IPC: F16K17/04
Filed: 1998-04-04
Abstract: A pressure-triggered safety valve releases fluid from a closed housing (18) for return through a pipe to a lower pressure zone. The housing has an intermediate piece (19) and a baseplate (14) with a pressure-relief valve (20) with a piston (7)  The piston is spring-loaded on one side. On the other, it has a hollow connecting rod (11) passing through a hole in the baseplate through the valve seat (9) center. The connecting rod end acts as a valve head (15) which forms an overflow valve in conjunction with a hollow chamber and outlet fitting (5).

Title: Yarn tension monitor has two monitor beams clamped at one end with the yarn passing partially round their free ends in opposite directions with sensors to register the beam bending to give signals to register the yarn tension
Inventor: BARTKOWIAK KLAUS
IPC: B65H59/40
Filed: 1999-01-19
Abstract: The mechanism to monitor yarn tension at a running yarn (5) has a monitor beam (1.1) which is clamped at one end and the yarn (5) path is deflected by the free end of the beam. A sensor (7) registers the beam (1.1) movement by the tension of the yarn (5) passing over the free end.  A second monitor beam (1.2), clamped at one end and fitted with a movement sensor (11), is at a gap from the first beam (1.1) along the yarn (5) path, for the yarn (5) to be deflected round its free end in the opposite direction to the deflection at the first beam. The yarn tension is determined from the sum of the bending movements at both beams as a result of the forces on their free ends by the tension of the deflected yarn. The specification is an addition to P19837414.3.  The yarn (5) follows an S- or Z-path between and partially around the free ends of the two monitor beams (1.1,1.2), in succession. The monitor beams (1.1,1.2) are between an entry and exit yarn guide, with a symmetrical alignment to the yarn (5) path so that the forces are equal on their free ends through the effects of the yarn tension as they are deflected round them. Each monitor beam (1.1,1.2) is fitted with a further sensor (8,12), at a gap from their first sensors (7,11) along the longitudinal line of the beams. The paired sensors (7,8;11,12) are at a bending beam (3.1,3.2), and the yarn (5) is carried through a guide (2.1,2.2) bonded to it. The sensors (7,8,11,12) are each of paired stretch measurement strips, secured to opposite surfaces of the monitor beams. The strips are linked together by a Wheatstone bridge circuit. The monitor beams can each be of two bending beams, with a rigid lateral beam linking their free ends together so that a deflection loading on them is in opposite directions. Each bending beam is fitted with one or more sensors (7,8). An Independent claim is included for a system to measure the tension of a running yarn, where the yarn is deflected round the free ends of two beams and their movement is measured to determine the tension of the yarn. Preferred Features: The measured value of the yarn tension is formed by an addition of the measurement signals which correspond to the bending action on the beams at the free ends where the yarn passes partially round them.

Inventor: BAIJENS MARK
IPC: B60T8/24
Filed: 1999-02-20
Abstract: The invention relates to a braking system wherein the braking setpoint value as specified by the driver or adjusted by an external braking device is detected on the basis of signals from a pressure sensor (22) and a displacement sensor (13). When the braking system includes, for instance, an active brake booster with an additional electromagnetic valve and a pedal or membrane displacement sensor for a brake servo unit, the plausibility of the pressure sensor (22) can be monitored and an additional redundant pressure sensor can thus be dispensed with.
