Patent EP-0272513-A3 (EP)
Title: Method for testing an interface unit
IPC: H04Q11/04
Filed: 1987-12-03
Abstract: In an interface unit (FAU) for connecting a PCM transmission path (PCM-Ü) to an exchange of a TDM telecommunications system, the supervisory circuits (Ü1 to Ün) of the system, which monitor information transmission criteria, should be monitored in such a way that their actual function is interrupted for a short time only. To achieve this, they are supplied successively with simulated parameters corresponding to an error event, even if they transmit one group- individual alarm signal only. If an error signal is produced, the supply of simulated parameters is immediately interrupted. If no error signal of this type occurs, the simulated parameters are fed in at least once more. <IMAGE>

Title: Injection molding filter
IPC: B01D29/50
Filed: 1987-08-12
Abstract: Apparatus is disclosed for filtering melted plastic used in an injection molding system. The apparatus consists of a housing (12) having an inlet (18) and outlet with a cylindrical inner chamber (21) disposed in alignment therebetween, and a tubular filter element (13) threadably mounted in the internal housing. To avoid loosening of the filter element (13), a plurality of spiral surfaces (34, 42) are formed in the filter element (13) that are exposed to the pressurized flow of melted plastic, generating a resultant force that tends to screw the filter element (13) tighter onto its threaded mount (22). The threaded mount (22) is at the inlet end of the tubular element (27), causing it to extend in cantilever fashion axially into the internal chamber (21) and toward the outlet. This creates an annular discharge passage around the filter element (13) that is unobstructed, permitting the filtered plastic to converge smoothly into the outlet.

Filed: 1988-08-11
Abstract: A butt connection for pipe lengths (1, 2) which consist of two concentric pipes of different diameters (outer and inner pipe 3 and 4), and carry in particular exhaust gases and combustion air from gas burners, comprises at least one axially movable collar (5), which connects the inner pipes (3) of these pipe lengths (1, 2), bridges a gap (a or b) existing between the end faces of the pipe lengths (1, 2) and consists of two sections offset with respect to one another, one of which has an internal diameter corresponding to the external diameter of one of the pipes (3, 4) and the other has an external diameter which corresponds to the internal diameter of one of the pipes (3, 4). The minimum length of one of the two sections corresponds to the maximum gap of the end faces of the two pipe lengths (1, 2) to be connected to one another. As a result of this dimensioning, a pipe length (2) which is initially movable can be guided onto a fixed-position pipe length (1) in a direction at right angles to the latter's axis and can then be connected to this fixed-position pipe length (1) simply by axially moving the collar (5). <IMAGE>
