Title: Micro-titration of coagulation reactions of plasma - subjected to delay phases but continuously mixed in heated measuring shaft
IPC: G01N33/49
Filed: 1990-11-28
Granted: 1992-01-30
Abstract: The heated material being tested is supplied under continuous intermixture, via a fine drawn supply capillary reaching the material under test, continuously and drop free. The material supply speed is tuned to a reaction specific delay kinetic and/or the reaction influencing reagent. The start of the coagulation is mechanically determined and the amount used at the reaction activating reagent serves as the measurement value. The determination results by a coagulation dependent viscometric conditioned deflection of a constant edge supply capillary (6) in a rotating circular cuvette (3). The system includes a heatable, upright standing measurement cell section (2), which provides the reception for the cuvette (3) and the supply of the reaction activating and/or reaction influencing agents is carried out by a pump (7-11) and a pipette mechanism (6,12-14). A supply capillary (6) near to the cuvette edge is equipped with a detector (4,5) to determine any lateral deflection of the supply capillary. ADVANTAGE - Gives automatic recording of inductor threshold concn. with coagulation tests facilitated by mechanical detection system.

Title: Determining internal noise levels in vehicle caused by servo pump - measuring output pressure of pump pulses to determine loudness of hum, whistle and hiss for different pump speeds and pressures
IPC: G01M13/00
Filed: 1991-06-27
Granted: 1992-09-24
Abstract: The method is for determining the noise component occurring inside the vehicle caused by the pump of a servo system, e.g. a servo hydraulic assisted steering system. At a test bed, the pressure pulses occurring at the output of the pump are measured and are compared with at least one specified limit value for evaluating the loudness of the servo steering system. The pressure pulsations for determining the loudness of the humming noise on the one hand, and for determining the hissing and whistling noises on the other hand, are measured with different static pump pressures and rotational speeds. ADVANTAGE - Tolerable and untolerable noises can be reliably identified.

ADVANTAGE - The process ensures that ethylene oxide cannot flow back into the reactor after the reaction is complete
Patent DE-4202232-C1 (DE)
IPC: B60K13/04
Filed: 1992-01-28
Granted: 1993-06-03
Abstract: For reducing IR detectability of an armored vehicle propelled by an internal combustion engine, the exhaust system includes a muffler connected to the internal combustion engine and an exhaust line connected to the muffler and opening into the atmosphere. The exhaust line branches into a first line and a second line whereby the first line has at least one opening within the bottom of the vehicle and the second line has an opening within one of the outer surfaces of the vehicle other than the bottom of the vehicle. A first flap closes the at least one opening within the bottom of the vehicle. A second flap closes the opening within one of the outer surfaces of the vehicle other than the bottom of the vehicle. In extreme situations, for example, when touching the ground surface, an undesirable increase of the exhaust gas counter pressure and thus an output reduction of the internal combustion engine is prevented by exhausting the gases through the second line, thereby partially loosing the IR detectability protection provided by the system.

Granted: 2008-04-08
Abstract: The process is for the installation of a building roof covering and involves the placement of a first layer of bituminous material (1) with an upper open surface (2a), which is initially covered by a removable first foil (3). After the removal of the first foil, a second layer of bituminous material (2) with a lower open surface is placed in reciprocal adhesion with the upper open surface of the first layer. The first layer of bituminous material has a polyester inlay reinforcement. The removable first foil is of polyethene or silicon. The under side (2b) of the bituminous layer is adhesive and on that side is a layer (4) of woven polyester fibers. The under layer (1) is supplied on a roll (5) in which the foil (3) is incorporated, which prevents the successive windings of the layer adhering to each other. An upper layer (20) also comprises a layer of modified bitumen with a polyester inlay. On its upper side (6a) is a layer of mineral material (7) such as sand. The under side (6b) is provided with an adhesive layer (8), on which a polyethene foil (9) is adhered. On installation this foil can be simply drawn away from the adhesive layer, so that the upper layer and the under layer can be adhered and laid on a roof without application of heat.
