Title: Gas pressure-operated fire fighting installation - uses inert pressure gas or air, superimposed on halogenated hydrocarbon without direct contact
Inventor: MUETZELBURG WOLFGANG
IPC: A62C13/66
Filed: 1980-02-19
Abstract: To prevent interaction between inert pressure gas, or pressurised air and halogenated hydrocarbon, the two media have to be separated. For this purpose the inert gas or pressurised air is admitted into a pressure pocket, after having passed a back pressure-controlled pressure reducing valve. The pressure pocket consists of a halogenated hydrocarbon resistant plastics material which is also impervious to osmotic pressure equalisation. The pocket is provided in the halogenated hydrocarbon container in a pressure-less condition. Instead of the pocket of plastics material a diaphragm, or a pressure loaded piston inside the cylindrical extinguishing agent container can be used. To produce the necessary pressure hydraulic pressure can be applied, which would also drive out the halogenated hydrocarbon from the container.

Title: Fluidic oscillator with resonant inertance and dynamic compliance circuit
IPC: C09J7/02
Filed: 1980-03-07
Abstract: The fluidic oscillator (14) includes a resonant fluid circuit having a fluid inertance and a dynamic fluid compliance. The inertance is a conduit (4) interconnecting two locations (16a, 16b) of a chamber on each side of a working fluid jet issuing into one end of the chamber (3), the inertance conduit transfers working fluid between the two locations. Through one or more output orifices (10), located at the opposite end of chamber (3), the fluid exits from an exit region (11) which is shaped to facilitate formation of a vortex (the dynamic compliance) from the entering fluid. The flow pattern in chamber (3), specially the vortex in exit region (11) provide flow aspiration on one side and surplus of flow on the opposite side of chamber (3), which effects accelerate and respectively decelerate the fluid in the inertance conduit (4) such as to cause reversal of the vortex after a time delay given by the inertance. The vortex in the exit region will cyclically alternate in velocity and direction of rotation to direct outflow through the output orifice such as to produce a cyclically repetitive side-to-side sweeping stream whose direction is determined, at any instant in time, as a function of the vectorial sum, at the output orifice, of the tangential vortex flow spin velocity vector and the static pressure vector and the dynamic pressure component, both directed radially from the vortex. By changing these parameters and by appropriately configuring the oscillator, sweep angle, oscillation frequency, distribution, outflow velocity, break up into droplets, etc. can be controlled over large ranges.

Title: 1-Out-of-N decoder for a semiconductor memory or the like, method of selecting one out of N lines in a matrix and address decoding circuit arrangement
Inventor: KLASS JEFFREY M
IPC: G11C16/08
Filed: 1981-02-04
Abstract: In the case of an electrically programmable memory matrix, which has rows and columns of floating-gate memory cells, output lines and earth lines are alternately used between the cell columns, which produces an arrangement with a virtual earth. A row is selected by one part of an address input signal, and a column is selected by a further part. An output line on one side of the selected column is activated, and an earth line is activated on the other side. A differential sense amplifier responds to the voltage on the selected output line and to a reference voltage. The number of transistors required in the decoder for the row selecting function is greatly reduced by using predecoders, which carry out a 1-out-of-4 selection for each pair of address bits, one of these selection output signals then being used to activate N multiplexers, and all the others being used as input signals of a decoder having N outputs to the multiplexers. <IMAGE>
