Patent DE-4235648-A1 (DE)
Inventor: RUTZ ANDREAS DR ING
IPC: B29C55/16
Filed: 1992-10-22
Abstract: The device according to the invention is in principle a film stretching system which consists of a first and a second separate conveying chain system (1, 2, 3, 4) with the associated guide tracks and tenter clips, the tenter clips being guided without the strap connections to one another, which are known per se. The first conveying chain system (1, 2) effects the clip conveying from the inlet as far as the fixing region of the system. There the clips are released from the conveying chain system and received by the second conveying chain system (3, 4). The conveying in the second system is carried out at a lower rate through the fixing region, the cooling region as far as the outlet from the system. The rate difference between the two conveying chains is the extent of the film shrinkage to be applied. <IMAGE>

Title: Embedded road device
Inventor: LIEDL ANTON
IPC: E01F9/529
Filed: 1993-04-01
Abstract: An embedded road device (10) has a lowerable top wall (14) which is held flush with the surface of the road by means of a spring (26) when not under load. When a vehicle wheel R runs onto the top wall (14), the latter can pivot to a greater or lesser extent depending on which of a few blocking members (28, 29) have been released. By actuation of two contact strips (32), in an electronic evaluation device (34) the travelling speed is computed and compared with a limit value. If the limit value is only slightly exceeded, the blocking members (28) are electromagnetically released, so that the top wall (14) can pivot to a limited extent. At greater speed excesses, the pivotability of the top wall (14) is increased. <IMAGE>

Title: Measuring standard for optical attenuation measurements
Inventor: HEITMANN WALTER DR ING
IPC: G01M11/00
Filed: 1993-04-22
Abstract: The invention relates to a measuring standard for optical attenuation measurements, consisting of an optical cable (2) having at least one artificially aged optical fibre (4) of known attenuation and known length in a cable sheath (6) which is filled with a viscous medium. The cable sheath (6) consists of a material which protects the optical fibre (4) in the long term against external influences, preferably made of stainless steel. A measuring standard is produced with which the long-term constancy of the attenuation coefficient within close tolerances is ensured for each partial section of the fibre. The measuring standard can consist of a plurality of partial fibre strands (8) of different lengths. Various partial measuring standards can thus be realised. For example, two of six partial fibre strands (8) can be connected by means of a permanent splice (10). The other fibre ends (9) end in each case in a connector socket (14). The connectors (14) can alternatively be brought into contact with each other or with the measuring device. Or, a measuring standard of maximum length can be produced from six partial strands (8). In this case, all the partial fibre strands (8) are connected in series with permanent splices (10). <IMAGE>

Patent DE-4325915-A1 (DE)
Title: Method for measuring humidity of a material web on a continuous drier and device for carrying out the method
IPC: G05D22/02
Filed: 1993-08-02
Abstract: The setting of the air outlet valve of a continuous drier such as, for example, a perforated cylinder drier, can be regulated in order to determine the air outlet humidity. This is expediently done as a function of the optimum drying power and as a function of the desired drying temperature of the material or of the outlet humidity thereof. According to the invention, provision is made for the temperature of the air after flow through the material web to be measured at least in the region of the outlet from the drier, and to be set in relation with the temperature of the surroundings, and thus the material temperature and thereby its humidity can be determined, since in the residual drying region the material humidity is a function of the material temperature. Using this measured value, the outlet-air humidity can be regulated. <IMAGE>
