The present invention is directed to a process for the production of molded polyurethane foams having a compact surface and a density of at least 250 kg/m3 by the in-mold foaming of a reaction mixture containing a) a polyisocyanate component containing at least one aromatic polyisocyanate, b) an isocyanate-reactive component containing at least one organic compound having at least two isocyanate-r...

Lock-out of pending higher high priority requests to a system controller is prevented by a circuit which comprises a counter element for counting the number of times the pending higher high priority request is not granted access. The counting results in a count value which is temporarily stored in the counter element. A compare element compares the count value to a predetermined value, the predete...

A sample of a normal data communications stream producing an error is thereafter employed via a loop back arrangement as a test sample data stream for error detection.

A hot tire forming method whereby at least some of the elements constituting each tire are formed starting from respective masterbatches, which are mixed with given chemical compounds inside respective continuous mixers to obtain respective final mixes, which are hot-fed to respective continuous production means, such as extruders, for obtaining semifinished products, which are hot-fed onto a fini...

An apparatus for displaying a travel path of a running body in which a direction detector includes a geomagnetism sensor as well as a rate-type sensor, such as gyroscope or gas rate sensor (which includes a flow sensor for detecting a degree of displacement of a gas flow produced by an angular velocity applied thereto) for detecting an angular velocity of change of yawing direction of the moving b...

Soluble gas is introduced in a melt material which is then atomized and rapidly cooled. The cooling drives the gas from solution, further disintegrating the atomized material to an ultra-fine powder. In one embodiment the atomization and rapid cooling are effected using a gas atomization die. Introduction of the soluble gas may be effected by addition of reactive constituents to the melt, for reac...
