Abstract: The present invention concerns a toilet seat (4) for composting toilets, said toilet seat comprising a seat ring (41), a bowl space (42), a bottom hole (42) of the bowl space, and separation means for liquids such as washing water and urine. The invention is implemented by adapting the inside surface (45) of the front part of the bowl space (42) to be at its upper part essentially vertical, at its middle part almost horizontal, and at its lower part convexly curved so that the center part of the curved area is closer to the rear part of the bowl space (42) than the start and end points of the convexly shaped lower part, whereby liquids entering the front part of the bowl space (42) in the toilet seat (4) are conducted along the inside surface of the front part into a separate liquids collection container, or alternatively, to a treatment process, and that the liquids separation means (5) are formed by a shutter (5) adapted to the lower part of the bowl space (42) or below it.

Title: Topping combustor for an indirect fired gas turbine
Inventor: PILLSBURY PAUL W
IPC: F02C3/20
Filed: 1992-08-21
Abstract: 56,940 ABSTRACT         A topping combustor is provided for a gas turbine power plant in which the combustion air from the compressor section of the gas turbine is heated in an indirect heat exchanger disposed  in a  solid  fuel  fired  furnace.   The compressed air from the compressor section flows through an annular passage enclosing the combustor inner shell on its way to the furnace, thereby cooling the inner shell.  A burner comprised of a fuel  distributor plate assembly having a plurality of fuel nozzles mounted therein is disposed in the inner vessel.   Further compressed and cooled air from the compressor section flows through the plate assembly and mixes with a conventional fuel supplied to the fuel nozzles.   A plurality of holes are formed in the plate assembly which distribute the combustion air around the nozzles.  The high combustion air temperature and low gas velocity downstream of the plate assembly allow stable combustion to occur at ultra-lean fuel/air ratios, thereby minimizing the formation of NOx.

Title: Bicmos output buffer noise reduction circuit
Inventor: OHANNES JAMES R
IPC: H03K19/003
Filed: 1992-12-04
Abstract: Attorney Docket No. NS18692 BICMOS OUTPUT BUFFER NOISE REDUCTION CIRCUIT          Abstract A BICMOS output buffer circuit delivers output signals of high and low potential levels at an output (VOUT) in response to data signals at an input (VIN). A CMOS output pulldown driver transistor (Q60) sources base drive current to a relatively large current conducting bipolar primary output pulldown transistor (Q44).  A relatively small current conducting CMOS secondary output pulldown transistor (Q60A) is coupled with primary current path in parallel with the primary current path of the bipolar primary output pulldown transistor (Q44) between the output (VOUT) and low potential power rail (GNDN).  The control gate node of CMOS secondary output pulldown transistor (Q60A) is coupled to the control gate node of the CMOS output pulldown driver transistor (Q60) to initiate pulldown of a small sinking current before turn on of the bipolar primary output pulldown transistor (Q44) to reduce the maximum peak output noise (VOLP).  A feed forward circuit capacitance is coupled between the control gate node of the CMOS output pulldown driver transistor (Q60) and base node of the bipolar output pulldown transistor (Q44).  The capacitance value is selected to pass a transient capacitive current sufficient for early turn on of the bipolar output pulldown transistor before the CMOS output pulldown driver transistor delivers sustained conduction current to reduce the maximum "valley" output noise (VOLV).

Title: Process for the purification of contaminated exhaust gases from incineration plants
Inventor: FATTINGER VOLKER
IPC: B01D53/34
Filed: 1992-08-10
Abstract: ABSTRACT     Described is a process for the purification, using regeneratable adsorption materials, of exhaust gases contaminated with at least SO2, a heavy metal (in particular mercury) and other toxic gases (in particular dioxins and furans) from incineration plants (1), in particular waste-incineration plants.  In order to be able to obtain pure, concentrated sulphuric acid and optionally also mercury, the process comprises the following steps:  the exhaust gas is passed through an adsorber (4) where it is freed from SO2, the heavy metal and the other toxic gases; the gas leaving the adsorber (4) is subjected, if necessary, to additional purification operations (5,7) and then released to the atmosphere; the contaminated adsorption material in the adsorber (4) is subjected to an oxygen-less regeneration operation (9); the rich gas arising from the regeneration operation (9) is fed to a gas scrubber (11) and then processed in a nitric oxide/sulphuric acid plant (12) to give pure sulphuric acid.

Title: Non-condensable purge control for refrigerant recycling system
Inventor: PFEFFERLE DEAN P
IPC: F25B43/04
Filed: 1993-06-24
Abstract: A refrigerant recycling system includes a recycled refrigerant tank for storing recycled refrigerant, and first and second valves connected in series between the recycled refrigerant tank and atmosphere. In purging non-condensables from the recycled refrigerant tank to atmosphere, a programmed microcontroller holds the first valve open for exposing the pressure transducer to the pressure in the recycled refrigerant tank, and opens the second valve when the measured pressure exceeds a predetermined pressure for purging non-condensables to atmosphere, holding the second valve open until the measured pressure drops below the predetermined pressure. The pressure checking and purging steps are repeated after a short period, as often as necessary until the measured pressure is less than or equal to the predetermined pressure while the second valve is closed and then, after a longer delay, the system goes through one more pressure check and, if necessary, purging operation.

One section of the stem co-acts with the sleeve to control the longitudinal position of the stem. Another section of the stem cooperates with an internal surface portion of the sleeve to provide a longitudinally extending flow passage for communicating from the inlet to the outlet.  A seal piece is mounted on the stem and is adapted for engagement with a stationary seating surface adjacent one end of the sleeve.  In operation, the seal piece is engaged with the seating surface only in the closed position for preventing flow to the flow passage.

Title: Process for the cleaning and protection, including corrosion protection, preservation and disinfection, of surfaces, and an agent for use in the process
Inventor: FAMME PER B
IPC: C11D11/00
Filed: 1992-03-25
Abstract: By a process for the cleaning and protection, including corrosion protection, preservation and disinfection, of all surfaces subjected to daily, periodic or current cleaning, and which between treatment and cleaning may be exposed to water having pH < 9, the cleaned surfaces are applied with a substance - preferably a plastic polymer - forming a dense, aseptic and water insoluble film, on which all dirt types can settle. The film is removed by wash with water having pH ã 9, whereby also the dirt settled on the film is removed. Thereafter the surfaces may be applied with a new film. Hereby it is possible without use of aggressive chemicals, hot water and pressure equipment, and without risk of build-up of resistant bacteria, in a very short time to perform cleaning and protection of rooms and equipment. Savings on water, energy, cleaning agents and personnel are obtained, and both internal and external environment are spared.
