Title: Non-destructive natural stress detection by ultrasound - using min. transit times of two orthogonal, polarised, transversal waves and measuring associated absorption coefft.
Inventor: SCHNEIDER ECKHARDT DIPL ING
IPC: G01N29/07
Filed: 1980-11-20
Abstract: The natural stresses in materials are non-destructively detected by a method using ultra-sound. The min. transit time of a linearly polarised transversed wave and the maximum transit time of a transversal wave, polarised orthogonally to the first one, are measured in a Cartesian coordinate system. The measurement considers also the propagation direction and the oscillation direction of the waves. The method also measures associated absorption coefficients, while the relative differences of indices are given by a computer. Tensile tests are used to provide the respective associated proportionality constants. The tensile differences are derived from specified equations for homogeneous materials free of texture and anisotropy. For other instances only the second equation is used.

Patent DE-3109362-A1 (DE)
Title: Electrical resistor
Inventor: BREMBILLA AUGUSTO DR ING
IPC: H01C3/20
Filed: 1981-03-12
Abstract: A resistor supporting body (TK2) within a housing (GH) carries out the function of axial tensile force transmission between terminating elements (AE2) on both sides on the ends of the housing (GH). This results in axial contact pressure, which is sufficient for retention and sealing, between the terminating elements and the housing without any special connecting elements, and in particular without bonding or the like to the housing ends. Terminating bonding work at high temperature is in consequence avoided during assembly, so that solder joints, especially soft-solder joints, can be provided on the individual components in order to fit cooling ducts to the housing. The axial tensile-force transmission between the supporting body (TK2) and the terminating elements (AE2) is expediently effected via positively-locking undercuts (BQ) on the supporting body, as a result of which joints by means such as welding or bonding for holding the resistor together are avoided and the heat transmission areas between the resistor body (WK) and the external connecting elements (AS) are reduced. <IMAGE>

Title: System for providing motor vehicles with early warning of emergency service vehicles
Inventor: HINKEL NORBERT
IPC: B60Q1/52
Filed: 1981-06-26
Abstract: A system for providing motor vehicles with early warning of emergency services vehicles is proposed, which system serves to provide prompt warning to drivers that emergency service vehicles (such as for example fire service, police, emergency medical services, ambulances etc.) are approaching. Above all this is intended to refer to vehicles for whose use special traffic regulations apply, for example higher speed, priority even at a red traffic light. The early warning system comprises a transmission component in the emergency vehicle and a reception and signalling component with audible and/or visual transmission in the motor vehicle. Vehicles performing an emergency function transmit, as well as the customary visual and audible signals, additional pulses or signals which can be received by appropriate devices in the motor vehicle. The received pulses/signals are decoded if necessary, amplified and converted in the motor vehicle into visual and/or audible signals which can be perceived by the driver of the vehicle (and passengers).

Patent DE-3145829-A1 (DE)
Title: Dabber printing method
IPC: B41M1/40
Filed: 1981-11-13
Abstract: The customary dabber printing method is improved in relation to the quality of a multicolour print by inking the rubber stamp using screen lithos. The screen-type distribution of the colours results in clear transitions between light and dark colours. The colours required are still only the base colours blue, yellow and red as well as the contrast colour black since mixed colours can be formed by dot-type screens of the base colours arranged adjacently. The intensity of the individual colours can be controlled by different etching of the blocks.
