Inventor: SONGER PAUL EUGENE
IPC: A62D3/00
Filed: 1987-01-05
Abstract: Atmospheric contamination by residual hazardous particles remaining on a substrate following removal from the substrate of a layer of material containing such particles is substantially reduced, by coating the substrate with certain aqueous coating compositions which produce tacky films on drying. For example, the health hazard from airborne asbestos fibers remaining attached to a substrate from which a layer of asbestos-containing material has been removed is substantially reduced by coating the substrate with an aqueous latex composition containing certain carboxylated butadiene styrene polymers.

Abstract: A communication protocol is provided to enable one of a number of transmitters using a common transmission line to independently gain exclusive use of the line. Before transmitting data, a transmitter first monitors the line to establish that it is idle. If it is, the transmitter then asserts the line for an interval unique to that given device. Thereafter the transmitter monitors the device momentarily to determine that no other transmitter is asserting the line and, if so, the transmitter may then gain exclusive control of the line.

Title: Process for the manufacture of an exhaust silencer
Inventor: GUSTAV SCHWEINFURTH
IPC: F01N1/24
Filed: 1989-08-04
Abstract: In a process for the manufacture of an exhaust silencer for motor vehicles, the advantages derived from employing mineral fiber mouldings are extensively retained while at the same time greatly reducing expenditure on shape-stabilization and transportation. To this end the silencer casing itself is divided in the meridian plane and the mineral wool is supplied and inserted directly into the original silencer casing in the form of precisely dimensioned prefabricated elements which have been impregnated with a suitable fluid, for example pretreated with synthetic resin, but not cured. This enables fast and reliable positioning of the impregnated and manually compressed prefabricated elements around the periphery of the exhaust pipe and the internal component containing the exhaust pipe inside the original silencer casing; once the silencer casing has been closed, the silencer is ready for installation. Curing, hardening or some other time consuming method of shape-stabilization is not necessary. Nevertheless, in comparison with packing the silencer casing with loose mineral wool, a more even fiber distribution is achieved, and the introduction of a specified quantity of fibers is assured through the employment of prefabricated elements, whereby the impregnation of the prefabricated elements renders them soft and pliable and thus easy to work with when placing them in position under compression.
