Patent DE-2609292-A1 (DE)
Title: Ferroelectric sodium nitrite element prodn. - by applying thin film to substrate from melt or soln., for radiation detector, memory etc.
Inventor: HETZLER ULLRICH DIPL PHYS
IPC: H01L37/02
Filed: 1976-03-06
Abstract: Prodn. of ferroelectric elements with Na nitrite (I) as ferroelectric involves the prodn. of thin (I) crystal films. The (I) film can be produced by dipping the substrate in molten (I) and/or applying molten (I) to the substrate and rotating to give a uniformly thin film. It is pref. to regulate the temp. gradient so that crystallisation starts at one point and to use an oriented seed crystal. The claims cover the use of the element as raduatuib detector, in field effect arrangements (ferroelectric field effect transistors (FEFET), i.e. integrated MIS (metal-insulator-Si) transistors with (I) replacing the insulator) and as memory device. The elements can be made easily and cheaply. The ferroelectric pref. axis is obtd. by heating the crystal film below the ferroelectric phase transition temp. of ca. 160 degrees and applying an electric field, pref. by crystallisation and or cooling in the electric field. (I) soln. can be used instead of molten (I).

Title: Air intake for sewage aeration tank - by axial water pump feeding several nozzles acting as air injection pumps
Inventor: KAELIN JOSEPH RICHARD
IPC: C02F3/12
Filed: 1976-10-29
Abstract: Air or oxygen is introduced into sewage in an aeration tank by accelerating the liq. by an axial pump and subdividing the flow into several nozzles. The gas is mixed with these side streams on the principle of a water-jet injector pump and the mixt. is compressed in the diffuser of a collector nozzle. The outflow is directed against the tank bottom at a speed which prevents the deposition of activated sludge. The pump requires no expensive redn. gear like a surface aerator. There is no danger of icing in winter causing an unbalance of the impeller. No atomised spray can pollute the environment and the fluid and gear noise is eliminated.

Title: Pilot controlled high pressure valve - has operating fluid fed to solenoid pilot valve via pressure reducing valve
Inventor: HAERTWIG MANFRED
IPC: F16K17/10
Filed: 1977-01-15
Abstract: The high-pressure stop valve is pilot-controlled by a solenoid valve whose operating fluid is derived from that to be controlled. The operating fluid is fed to the pilot valve via a pressure-reducing valve. The plug of the main valve can be actuated by a plunger working in an intermediate portion of the valve housing, and which also accommodates the reducing valve. Pilot and main valves can operate on a common axis. The ratio of the effective surface of the plunger to that of the main valve plug can be matched to the force exerted by the solenoid valve, and to the pressure supplied by the reducing valve.

Title: Ultrasonic tube wall strength tester - uses two separate energy pulses and reflector-receiver converter combination inside tube
Inventor: FLOURNOY NORMAN EUSTACE
IPC: G01S15/88
Filed: 1977-03-10
Abstract: A method of ultrasonic sound detection of the wall strength of tubes, directs an energy pulse onto the tube wall at right angles to the longitudinal axis of the tube. The reflected pulse is captured by a pulse reflector, receiver, converter combination (25, 30, 45). A second pulse is directed onto the wall so that its angle of attack is greater than the critical refraction angle. With an irregularity in the wall surface this second reflected pulse is time shifted relative to the first pulse on arrival at the receiver. The single pulse is split so that part is at less than 45 deg. to the reflection surface and part at more than 45 deg. to the surface. A series of energy pulses may be used and in all directions within the tube at right angles to the longitudinal tube axis.

Abstract: A gas generator intended esp. for safety equipment in automobiles, such as the drive of a rapid-reeling safety belt device, comprises a combustion chamber in which granulated material is contained at a sufficient density to produce rapid but not excessively rapid combustion. The combustion chamber is cylindrical and is subdivided by a piston in the initial state this piston retains the granulate at one end of the cylinder, whereas when the granulate has been detonated the resultant gas pressure forces back the piston to a second position, in which the volume of the combustion chamber provides the correct density of the charge, i.e. ratio of granulate to combustion chamber volume. For any use in an automobile, as described but also for the inflatable bag safety system. The generator may also be used for inflatable boats.
