Abstract: ABSTRACT OF THE DISCLOSURE         A two-terminal-pair circuit which simulates an inductance includes input and output terminal pairs and a first ohmic resistor.  The voltage-carrying terminal of the input terminal pair is connected to one terminal of the first ohmic resistor.  The circuit includes a bridge circuit having bridge branches and two opposite bridge diagonal terminals, two capacitors each connecting a respective one of the two bridge diagonal terminals to a respective one of the terminals of the first ohmic resistor, and a difference amplifier having two inputs each connected to a respective one of the two bridge diagonal terminals.  The output of the dif-ference amplifier is connected to the base of a transistor whose collector-emitter path is connected in one of the bridge branches in series with an effective resistor or with a paral-lel circuit comprising a capacitive reactance and an effective resistor.  The emitter of the transistor is connected to the other terminal of the first resistor, and the collector of the transistor forms the voltage-carrying terminal of the output terminal pair.

Title: Method and apparatus for purifying air charged with  pollutants
Inventor: HOELTER HEINZ
IPC: B60H3/06
Filed: 1981-10-16
Granted: 1984-12-18
Abstract: ABSTRACT         The invention relates to a method and apparatus for purifying air, using both catalytic and sorptive substances. The invention seeks to eliminate pollutants from air, with simultaneous utilization of both sorptive and catalytic substances, while ensuring that the said substances have relatively long lives.  This is achieved by feeding air charged with pollutants, such as SO2, NO2, NO and HC compounds, in sequence through a filter, and a soda-lime layer, followed by a partial oxidation of the remaining oxides, i.e. NO to NO2, by a catalyst layer, such as hopcalite.  The air is then passed through an activated-charcoal layer, heated by a heating device, and finally passed to a second catalyst layer in order to convert CO into CO2.  It is preferred to have a cooling zone subsequent to the hopcalite layer.

Abstract: ABSTRACT OF THE DISCLOSURE A method of recovering natural gas entrapped in frozen subsurface gas hydrate formations  in arctic regions. A hot  supersaturatad  solution  of  CaC12  or  CaBr2,  or  a mixture thereof, is pumped under pressure down a wellbore and  into  a  subsurface  hydrate  formation  80 as  to hydrostatically     fracture     the     formation.      The CaCl2/CaBr2  solution  dissolves  the  solid  hydrates  and thereby releases the gas entrapped therein.  Additionally the  solution  contains  a polymeric  viscosifier,  which operates   to  maintain   in  suspension  finely  divided crystalline   CaC12/CaBr2   that   prscipitates   from   the supersaturated solution as it is cooled during injection into  the  formation.   The  crystallized  CaC12/CaBr2  is distributed while  so  suspended  throughout  the  formation and is available to be dissolved in water that is released during dissolution of the solid hydrates, thereby forming additionally  CaC12/CaBr2  brine  in  situ  and  extending the  reaction  further  into  the  formation  than  could otherwise be obtained without the viscosifier.

Abstract: RETARDING SYSTEM OF A GAS                COMPRESSION RELIEF TYPE              ABSTRACT OF THE DISCLOSURE         A hydraulic reset mechanism is provided for an engine retarder of the compression relief type.  The mechanism includes a pin valve and senses the force required to hold open an exhaust valve.  When this force has decreased substantially from the force required to open the exhaust valve initially, the pin valve is opened in the hydraulic system to release the hydraulic pressure and permit the exhaust valve to close.  The mechanism thereby assures that the engine exhaust valves are closed, or substantially closed, prior to the normal opening of the exhaust valves at the end of the power stroke of the engine without affecting the retarding horsepower produced by the engine brake.
