Patent DE-19644290-A1 (DE)
Title: Sensor for simultaneous measurement of two properties of substance in fluid
Inventor: ROTH MATHIAS DIPL PHYS
IPC: G01N27/22
Filed: 1996-10-24
Abstract: The sensor (10) consists of a quartz substrate (12) coated with a substance (30) which is chemically sensitive to a component in the fluid. Two arrangements of sensors (12,14a,14b and on line AA') are provided to detect changes in a property, e.g. the mechanical and electrical properties, of the chemically active substance. The electrical property detected may be the dielectric constant or the conductivity. The mechanical property may be the mass, viscosity or shear strength. The first set of sensors (12,14a,14b) consists of metallic electrodes attached to the substrate such that a piezoelectric oscillation is produced in the substrate as a result of electric oscillations applied to the two electrodes (14a,14b). The second set of sensors (on AA') uses an interdigital capacitor whose capacitance or conductivity changes with the chemically active substance, to measure the electrical properties. A heater and temperature sensor may be fitted in addition.

Title: Two-sided door opener for room doors
Inventor: HOPF BENJAMIN
IPC: E05B1/00
Filed: 1997-01-08
Abstract: The door opener (2) has a handle (5) which is arranged in a circular door hole (6) and can be reached and operated from both sides of the door. The handle is half-round with an outside radius equal to that of the door hole so that it can slide in the door hole and be turned about the hole centre (M) when operated. The handle may be carried by a roller bearing and when fitted at its circumference with a guide, this slots into a recess in the door opening which in turn has turning limits acting as endstops for the handle guide. The door hole may be rimmed by a covering made up of two profiles which telescope together over the thickness of the door. The handle can be locked to prevent turning and it may comprise two similar half-round parts which stand in parallel until turned relative to one another to close off the door opening. The handle movement can be transmitted to activate the door latch (4) via a toothed mechanism.

Title: Pull tension distribution measurement method for in metal band
Inventor: BERGHS ANDRE DIPL ING
IPC: B21B38/02
Filed: 1998-01-29
Abstract: The method involves measuring a pull tension distribution over the entire width of a metal band between two milling arrangements or between a milling arrangement and a reel or a roll. A force is exerted on the metal band by an electromagnetic field, which causes a movement of the metal band. The movement of the metal band is measured and is used for the calculation of the pull tension distribution over the width of the metal band. An alternating electromagnetic field, especially with a frequency between 1 to 200 Hz, is preferably used, to produce a periodic force which causes a periodic movement, i.e. a bent wave, especially in a longitudinal direction of the metal band.
