Patent DE-4403030-A1 (DE)
Title: Deceleration-dependent pressure control valve for vehicle brake systems
Inventor: GILLES LEO
IPC: B60T8/26
Filed: 1994-02-01
Abstract: A valve housing (10) has a fluid inlet (20), a fluid outlet (50) and a stepped cylinder (14, 36) arranged between them, in which a stepped piston (38) is guided. Cylinder chambers (30, 40), which are connected to one another by a passage (42), adjoin the two end faces of the stepped piston (38). The passage (42) has a valve seat (44), against which a valve body (32), movable in the valve housing (10) as a function of the deceleration, can be applied in order to shut off the passage (42). A solenoid (60) is fitted to the valve housing (10), by means of which the valve body (32) can also be moved independently of the deceleration. This provides facilities, under certain conditions, for adjusting the switching behaviour of the pressure control valve. <IMAGE>

Title: Rehabilitation of perforated pipes esp. waste water pipes
Inventor: ZIEGLER JOSEF
IPC: F16L55/165
Filed: 1994-02-04
Abstract: Pipes (10) are rehabilitated by drawing through them a woven tube (16) soaked in hardenable synthetic resin.  Pref. a pipe (10) with a perforations (12) has a repair tube (16) of woven fabric impregnated with a resin drawn through it which is then bonded in position. The tube has a twill or plain weave and is made of natural, synthetic or glass fibre or a blend. The woven tube (16) can be surrounded by a synthetic tube (18), e.g. a PVC, which is not soaked in resin and prevents direct contact with the inner wall of the pipe (10). An inner synthetic tube (20) contains a rubber liner (22) which is placed under a pressure of about 100 bar to act as support during curing of the synthetic resin. After curing the inner synthetic tube (20) and the rubber liner (22) are withdrawn.

Patent DE-4414619-A1 (DE)
Title: Large contaminated moistened granular mixture physico-chemical measurement method
Inventor: GOLDMANN THOMAS DR RER NAT
IPC: G01N27/04
Filed: 1994-04-18
Abstract: The method involves pacing mixture under the influence of electrical fields and hydrostatic pressure to produce electro-kinetic and hydraulic transport movements. The electric potentials and electrical quantities of flow rate, pH values and mobilities of the sample fluid are then measured.Also measured are losses through electrode reactions and which are acquired and processed by a computer in the system. By applying a hydraulic pressure and/or an electrical field to the sample the hydraulic flow rate relative to the electrostatic flow rate and diverted values singly and in transit are measured. The electro-osmosis flow rate and the derived size are measured both singly and superimposed.

Patent DE-4431996-A1 (DE)
Title: Fuel feed device
Inventor: OI KIYOTOSHI
IPC: F02M37/22
Filed: 1994-09-08
Abstract: A fuel pump, which is fitted in a fuel tank, is proposed, which can be easily installed and reduces vibrations which are generated by the fuel pump. The fuel pumped by one pump section (20) flows through a filter (24) for the retention of foreign bodies. Thereafter the fuel flows from a passage (26) by way of an opening section (29a) in a cap (29) into a recess (31) and a second passage (32). The fuel in the second passage (32) lifts a non-return valve (43) and flows into a recess (51). From there the fuel flows by way of a third passage (52) to a discharge line (11), whereupon it is led to the outside of the fuel tank. A ball (34) is arranged so that it is capable of moving according to the fuel pressure within a section (33b) of larger diameter, in order to adjust the fuel pressure which is required for injection. When the pumping sequence is interrupted, the fuel pressure falls to zero, the ball (34) being pressed on a valve seat (36) by the force of a compression spring (35). The head (43b) of the non-return valve (43) is hereupon pressed on a valve seat (44) in order to close off the passage. The residual fuel pressure can be maintained downstream of the recess (51). <IMAGE>

Patent DE-4440619-A1 (DE)
Title: Nuclear magnetic resonance appts.
Inventor: MISIC GEORGE J
IPC: G08C17/02
Filed: 1994-11-14
Abstract: A surface coil arrangement (18) produces a radio frequency signal via a connector (20). A modulator (22) connected to the connector modulates the RF signal onto a carrier wave with a first frequency different from that of the RF signal. A transmitter (24,26) coupled to the modulator transfers the modulated signal close to the first frequency. A receiver (28,30) remote from the transmitter receives the signal wirelessly close to the first frequency. A demodulator (32) connected to the receiver demodulates the signal to produce a reconstructed RF signal. A magnetic resonance base system (36) coupled to the demodulator receives the reconstructed RF signal from it. The first frequency is higher than the magnetic resonance Larmour frequency.

Patent WO-8904480-A1 (WO)
Title: Electrochemical sensor
Inventor: FRIESE KARL-HERMANN
IPC: G01N27/416
Filed: 1988-10-13
Abstract: An electrochemical sensor for measuring the oxygen content of gases, in particular exhaust gases from internal combustion engines, comprises a solid electrolyte of zirconium dioxide and/or other oxides which conduct oxygen ions and at least one electrode arranged on the side of the solid electrolyte exposed to the gas to be measured. The electrode(s) may contain a ceramic supporting skeleton and the electrode(s) exposed to the gas to be measured is (are) covered with a porous ceramic protective coating of an Al2O3- and/or Mg spinel (MgO.Al2O3) matrix in which preferably metastable ZrO2 particles are embedded. The use of a mixed oxide system of Al2O3/ZrO2, which may contain a stabilizer for the ZrO2, and which is preferably obtained by coprecipitation or by combination of suspensions of separately precipitated components or by spray calcination of a common solution of salts of the components, makes it possible in a surprising way to obtain a sintered adhesive protective layer with a relatively narrow pore size distribution which allows the optimal passage of gas to the outer electrode of the sensor. The use of the Al2O3/ZrO2 mixed oxide powder also makes it possible to compensate to a very large extent for the previously observed disproportion between the mechanical stresses and the adhesive strength of the layer and to obtain the desired porosity and regulating position of the sensor.
