Title: Metallic seal for high pressure and temp. - has coated sealing ring integral with stopper to prevent coating damage
Inventor: KLEIN WILLI
IPC: F16L43/00
Filed: 1973-06-26
Abstract: The traverse locking bar has through it a bolt to which the cone-shaped stopper is attached. The metallic sealing ring with its ductile coating is placed onto the cone. A bayonet locking pressure plate is placed above it. The stopper assembly is lowered into the vessel, and, without disturbing the seal, is turned into the locked position. Because the sealing ring does not move, the coating can be pure nickle or any other material which is considerably more ductile than the base material. Finally the nut on the traverse bar is tightened in the usual way.

Title: Tube post station - has flap held shut by vacuum or locked shut under pressure
Inventor: TONNE FRIEDRICH DIPL ING
IPC: B65G51/26
Filed: 1974-02-15
Abstract: The station is for suction or pressure operation, having a flap shutting off the tube, which with suction operation is held shut by the vacuum in the pipe. With pressure operation a mechanical locking device, preferably a stop, prevents it flying open. An annular sealing lip can be provided, running parallel to the flap round the edge of the tube. Pressure in the tube forces this against the flap to form an airtight seal, maintained even if the flap is lifted. The flap can be slid by hand in relation to the stop between the rest position for suction operation and the locked position for pressure operation.

Title: Proportional-integral-derivative controller with overshoot limitation - uses transistor gate to trigger output power break
Inventor: SCHELER MANFRED DIPL ING
IPC: G05B11/42
Filed: 1974-03-21
Abstract: A proportional-integral-derivative control regulator has a switching transistor built-in to prevent overshoot of the reference value when the input changes rapidly between two extreme values. The proportional amplifier generates a difference signal that is passed over a series resistor, zener diode to the base of a transistor. A second differencing amplifier has a feedback loop with an integrating capacitor and a differentiating capacitor. The base voltage divider of the transistor is selected so that the transistor is inhibited when the difference signal falls below a certain value. This ensures that the power supply to the load is blocked for a predetermined time period so that overshoot of the required value cannot occur.

Title: High power electromagnet of defined force and displacement character - uses variable pole areas for magnetic force dependent on stroke and pole area
Inventor: KASTEN HEINZ DIPL PHYS
IPC: H01F7/13
Filed: 1974-07-13
Abstract: The electromagnet consists of a yoke carrying the coil and a guided, movable, soft iron armature. The armature and yoke have overlapping pole areas carrying the magnetic flux. The size of the pole areas is a function of the armature displacement. The lifting electromagnet of high efficiency has the magnetic force, as a function of the displacement, defined by the change of overlaps of opposing pole areas of the armature and yoke. The overlapping areas from the pole surfaces and the air gap between the yoke and armature is mainly constant. For two overlapping areas the following results occur for armature displacement: for countercurrent, complementary overlapping the magnetic force is proportional to the displacement; for synonymous overlapping the magnetic force is independent of displacement.

Title: Measuring tape breaking mechanism for ergometer wheels - has braking tape surrounding brake drum by more than one revolution
Inventor: SVENSSON ARNE BEJERT
IPC: A61B5/22
Filed: 1974-10-07
Abstract: At least one end of the measuring tape is free and to this end is applied a measuring force which alone determines the braking power. The tape loop angle is so selected that the force at the other end of the tape is negligeable. The force at the other end can, owing to the choice of angle of loop, be so adapted that it compensates losses in bearings and in any transmission that is present. The measuring force can consist of the force of gravity of unit weights. It can be applied to the free end of the tape by means of a balance which can be a pendulum or spring balance.
