Title: Cooling tower - has glass plates as trickle assembly with surface structuring to give serpentine path across air flow
Inventor: CRAMMER RAIMUND DIPL CHEM
IPC: F28F25/08
Filed: 1990-01-24
Abstract: The cooling tower, particularly for treating coolant water in a power station, has a trickle cooler assembly, where the trickle plates are self-supporting glass panes with both their surfaces treated to give macroscopic structures to form serpentine flow paths. The air flow is optimised throught he gap width of the space gap. Pref. the glass plates have a thickness of about 4 mm and more. The glass surface structures are aligned at least across the main air flow direction to stretch by the glass thickness of 2-6 mm. pref. about 4 mm. The structuring is by grooves across the main air flow direction or as isolated spots arranged in rows with displacement between the rows. The glass surface structuring is by impression, printing and/or galvano application and/or by enamelling. The glass surface structure can also be formed by etching. The surfaces of the glass surface structuring and/or the zones between the structures can be roughened microscopically to aid wetting. The glass plates in the trickle assembly have a space gap with a gap width covered in a projection towards the space gap from the surface structures. The glass plates are assembled with distance holders into a packet to be mounted and dismantled in the trickle system as blocks. The edges of the glass plates are reinforced to be supported by carrier beams. The distance mountings are bonding belts aligned at an angle to the flow direction.

Title: Audio signal processing for stereo headphone - adjusting stereo spectrum width or original audio signal and feeding back variable intensity
Inventor: KOENIG FLORIAN DIPL ING
IPC: H04R5/033
Filed: 1990-03-12
Abstract: Starting from an arbitrary, original audio signal, its stereo sound spectrum width is variably adjusted. It is then fed back with a variable intensity to the original signal. The two signal components of the generated stereo signal are variably mixed, with a delay, feedback, and their intensity. Then the two signal components are passed through separately adjustable filters to simulate time dependent, variable, two-ear, outer ear transmission functions. The stereo signal components are several times, variably, intensity dependent delayed, frequency distorted and mixed for simulating three-dimensionally, directionally independent, localised room reflections. ADVANTAGE - Almost real, natural audio signal reception and reproduction by stereo headphones.

Title: Oxygen concn. sensor for gas mixt. has heater - operable at two different potentials to minimise preparation time
Inventor: MURASE TAKAO
IPC: G01N27/406
Filed: 1990-10-23
Abstract: O2 concn. in an atmos. is measured by a section of a sensor heated to suitable operating temp. by an electrical heater. The heating element is supplied with one of two potentials. The first represents the strength needed to hold the sensor at a specific operating temp.. The second potential is higher, and is applied for a period needed to raise the element to the operating temp. before the lower first potential is applied. The two potentials may derive from twin sources, controlled by switches to apply the higher value for e.g., 5-60 seconds. The heating element may be incorporated in an insulating ceramic layer. A diffusion resistance bounding a gas-diffusion chamber contacting the external atmos. has a defined resistance to diffusing test-gas, and an O2 pump responds to the sensor output signal. The sensor itself has two electrodes on a layer of ceramic zirconia permeable to O2 ions. USE/ADVANTAGE - For measuring fuel/air ratio in IC engines, boiler plant, etc.. Sensor is rapidly brought to correct temp. without overheating risk.
