Patent DE-19854499-A1 (DE)
Title: Godet roller
Inventor: RITTER WALTER
IPC: D02J1/22
Filed: 1998-11-25
Abstract: The godet roller assembly, to feed a continuous synthetic filament yarn, has a bearing housing between the roller mantle and electromotor with an inner bearing carrier and an outer cooling body, bonded together to provide a heat conductive contact with the cooling body. The cooling body material has a higher thermal conductivity than the bearing carrier material. The end sides of the bearing carrier (13) have bearing drillings linked to a shaft drilling (16) of a smaller diameter and concentric to them. A narrow air gap (22) is formed between the shaft (1) and bearing carrier (13) at the shaft drilling (16). At the shaft drilling (16), the bearing carrier (13) has a number of cut recesses (21) round the periphery, to be occupied by matching pins (20) at the cooling body (12). The cut recesses (21) pass completely through the mantle of the bearing carrier (13). The bearing carrier can have two ring carrier segments at the end sides of the cooling body (12), each with a bearing drilling (14,15). They are linked to the smaller diameter and concentric shaft drilling (16) with an air gap (22) between the shaft (1) and cooling body (12) at the shaft drilling (16). The cooling body (12) has axial cooling ribs (24) on its outer circumference, bonded to a drive housing (17) at the drive side.  A fan (19) within the drive housing (17) generates an axial cooling air stream. A number of openings are between a fixed horizontal and hollow cylindrical carrier, pushed over the shaft (1) within the mantle (2), to carry the heater to heat the mantle and the bearing housing (11), to link the outer atmosphere to the ring space formed between the shaft (1) and carrier. A collar at the cylindrical carrier is a mounting for the cooling body (12) at the bearing housing (11).  Openings are between adjacent cooling ribs (24), at the cooling body (12) and collar, to deliver a cooling air stream at least partially into the ring zone. The collar is at the circumference of the cooling ribs (24) of the cooling body (12). A lateral web is between several adjacent cooling ribs (24) over part of the cooling body (12) circumference, to divide the cooling air stream into two flows. An insulation body is in the ring space between the shaft (1) and cylindrical carrier. At least one radial displacement body at the shaft (1) extends into the ring space.

Inventor: STAHL ROLAND
IPC: G01N27/416
Filed: 1999-07-02
Abstract: The invention relates to an electrochemical gas sensor and to a method for determining the concentration of gas components in a gaseous mixture, in particular the concentration of NOx in exhaust gases from internal combustion engines. The gas sensor comprises a first gas measuring chamber (13) which comes into contact with the gas to be measured and two additional gas measuring chambers (15) and (17) which are connected to the first gas measuring chamber (13) via diffusion barriers (25) and (27).

The gas measuring chambers (15, 17) contain additional pump cells, whereby the gas measuring chamber (15) is used to measure the oxygen concentration in the mixture and the gas measuring chamber (17) is used to measure the sum of the oxygen concentration and the concentration of gas components in the gaseous mixture. The pump current which is measured between two pump electrodes (31, 33, 35), located on a fixed electrolyte is used by the two amperometric measuring cells as a measurement variable and by calculating the difference between both pump currents, a measuring signal is obtained which is proportional to the concentration of the gas components to be determined.
