Patent DE-19751597-A1 (DE)
Title: Portable rebreather apparatus for emergency inhalation anesthesia in remote locations
Inventor: WALLROTH CARL F
IPC: A61M16/01
Filed: 1997-11-21
Abstract: The respiration gas line (16,2,7) is supplied with oxygen by chlorate cartridges (21,22) incorporating ignition devices (23,24) with oxygen stored in a reservoir (19) and a pressure sensor (20).  The sensor signals to a controller (25) on registering a low pressure, igniting another cartridge automatically. First and second control valves (17,18), situated between oxygen source and respiration line, have oxygen and ambient dilution air flowing. A sensor (9) measures delivered oxygen concentration, while a second controller (30) connected to this sensor and the control valves, maintains the required oxygen concentration for respiration. A xenon gas source (26) is connected to the gas supply line. The respiration circuit (6) includes a respiration gas line, with anesthetic gas supply unit (10) and anesthetic gas vent valve (15) connected to the second controller along with a carbon dioxide absorber (11). An activated carbon filter (12) with bypass line (14) and valve (13), enable respiration gas to be switched over to the filter. A unit determines anesthetic gas concentration, carbon dioxide concentration and respiratory passage pressure, integrated with a measurement device (9). Chlorate cartridges are filled with differing chemicals (to vary supply composition).

Patent DE-19815616-A1 (DE)
IPC: C02F3/22
Filed: 1998-04-07
Abstract: The invention relates to a method and device for purifying waste water, especially by means of anaerobic purification. The inventive method is carried out in a tank (19) containing waste water and sludge and involves the production of gas. The gas thus formed is collected by a gas collector (3) and the circulation system that arises as a result of the ascending gas is used to loosen the sludge that has settled on the bottom of the tank (19). The aim of the invention is to provide a more effective method with a simple constructive design. To achieve this, the settled sludge is suctioned away from the bottom using the lifting effect provided by the ascending gas and is conducted to the upper part of the tank separately from the waste water contained in said tank before being reintroduced into the waste water.

Title: Stripping process for producing e.g. soluble coffee from ground roasted beans
IPC: C11B9/02
Filed: 1998-06-12
Abstract: Plant matter is treated with saturated steam to strip aroma and flavor substances while pressure and temperature are raised continuously. Plant matter (especially ground coffee beans) is treated with saturated steam to strip aroma and flavor substances while pressure and temperature are raised continuously. The steam is cooled to 2-5 deg C, recovering condensed concentrate. Residual beans are extracted at low temperatures (LT) of 60-120 deg C and 20-40 bar. The extract is let-down and the vapor condensed and cooled. This concentrate is sent to a centrifugal column where it is stripped with saturated steam which is cooled and condensed together with flavoring substances. Residual beans from LT extraction are further extracted at high temperatures (HT) of 160-220 deg C, followed by extract expansion, cooling and condensation, and recovering the liquid portion of HT extraction. The condensate is disposed of. The extract from respective stages is concentrated. Following HT extraction (P8-P11) the residual beans undergo an ultra high temperature (UHT) extraction (P12) at 180-230 deg C, the extract being cooled and condensed. Condensate is discarded and the liquid portion is recovered as UHT extract.  Preferred features: Roasting precedes extraction. The roasted coffee beans have a moisture content of about 10 wt.%. Comminuted matter is ground down from a mean grading of 1.8 mm. Initial treatment takes place in a percolator, the grading increasing from about 2 mm to about 3 mm over its height.

Title: Old oil testing detector for objective measurement of lubricating ability of used engine oil still existing
IPC: G01N19/02
Filed: 1998-12-18
Abstract: The detector measures the structural viscosity taken with the running ability of the oil as boundary layer friction on tribometric or viscosimetric basis and determines the lubricating ability of the oil. The detector measures the structural viscosity taken with the running power of the oil, as boundary layer friction on a tribometric or a viscosimetric basis. The lubricating ability of the oil is determined by the frictional coefficients, which are measured from the quotients of the pressure force, measured as the deformation caused on a semiconductor strain gauge (5) and related to the rotation surface (9) and the force transmitted through the liquid. The force transmitted through the liquid is measured as the deformation of a semiconductor strain gauge (14) and related to the beaker surface (10). When the distance between the frictional surfaces is increase, the elasticity of the carrier surfaces (13) is simultaneously increased. The deformation of the strain gauges is output to a differential amplifier and displayed. Different structural viscosities of fresh oil can be compensated for using variable resistances. Variations of the surrounding temperature between 20  deg C and 30  deg C in several steps can be accounted for using the variable resistances.
