Abstract: A heat sensitive cable operable over a temperature range of between approximately -30°C and 900°C. The cable Includes a tubular metallic sheath which is substantially temperature resistant and moisture impervious. It also includes a mass of compacted insulation material filling the sheath and having an insulation resistance variable with temperature in the range of between approximately 100 and 50,000 ohms. The cable further Includes at least one thermoelectric conductor positioned within the insulation material filling the sheath. A method of manufacturing the cable includes the step of preparing the insulation material and advancing the thermoelectric conductor through a given region. It also includes the step of advancing a strip of flat metal material past apparatus for forming and welding a tubular sheath surrounding the given region. The method further includes the step of concurrently depositing the insulation material within the tubular sheath for enclosure and advancing the sheath, insulation material and conductor through apparatus for reducing the diameter of the sheath and applying tension to the conductor. With these steps, the insulation material is compacted and the conductor is positioned within the sheath.

Abstract: The components of the coupling for pressure lines are a female coupling (1) and a male coupling (2). The female coupling (1) has two adjacent axial bores (3; 4) of different diameters. An annular groove (5) around the smaller bore (4) is formed coaxially with the bores (3; 4) from the larger bore (3) side. When the coupling components (1; 2) are fitted together, the male coupling (2) is inserted into the bore (3) of the female coupling (1). Here, the male coupling (2) is pushed over the nipple (6) formed by the annular groove (5) and the smaller bore (4). The seal fitted in the male coupling (2) sealingly engages the smooth outer surface (7) of the nipple (6). The shape of the female coupling (1) and the mating male coupling (2) makes coupling and uncoupling with a predetermined flow cross section possible with less force than with prior art couplings.

Abstract: For establishing two-way communication links between processes in a distributed operating system, the processes are provided with ports through which communication between the processes is performed. The processes and the ports make possible for the operating system to keep a check on processes having links and to use these links also if the process per se is terminated, and to discover an error in the process and terminate it. For enabling the operating system to be able to transmit via the links information regarding process or computer drop out and thus be able to propagate this information through the whole chain of linked processes, and to report this information to applications executed in the linked processes in order to enable these to undertake application specific measures, a code is used which is called at link abortion and communication errors. The function of this code includes terminating an erroneous process and reporting the error to an error handling code. The first mentioned code is always executing in a process to which an error has been reported.
