Patent EP-0297861-A3 (EP)
IPC: F16L27/108
Filed: 1988-06-30
Abstract: A tuned, convoluted, stainless steel conduit 
assembly is especially well adapted for use in hostile 
environments subject to vibrations which bring on 
fatigue failures. To prevent the conduit from having a 
uniform resonance throughout its length, the 
convolutions have a variable wall thickness. One way 
this variable wall thickness may be achieved is by 
forming the conduit walls by wrapping stainless steel 
tape in successive layers (32, 34, 36) to form a 
multiple layered wall. The width of the tape may be 
such that some convolutions have more layers than other 
neighboring convolutions. A stainless steel sleeve 
or stocking (100) loosely fits over the conduit and is 
clamped by one or more tuning bands (108) onto the 
conduit to prevent vibration of the conduit at that 
clamped location.

Patent EP-0326839-A3 (EP)
Title: Sealing system with an annular, elastic and deformable sealing and its application
IPC: F16K3/08
Filed: 1989-01-16
Abstract: The sealing arrangement comprises a seal having end sealing surfaces. The one end sealing surface bears against an annular sealing surface of a valve seat screwed into a lower part of a water faucet. The other end sealing surface presses upon a non-rotatable disk which bears against a rotary disk. The seal comprises radially outwardly projecting supporting ribs in the region of the end sealing surfaces. These supporting ribs are supported at a supporting ring of a housing of a ceramic upper part or portion. A slit spring washer bears against the seal at the inner or internal side thereof. With this sealing arrangement it is rendered possible that the seal has to be fitted into the water faucet with only a small bias or loading, because the seal efficiently utilizes the water pressure and converts or transforms such water pressure into a force which presses the end sealing surfaces with greaater compression or pressure against the annular sealing surface and the non-rotatable disk, respectively.

Title: Matched spectral null trellis codes for partial response channels
IPC: H04L25/49
Filed: 1989-02-15
Abstract: A method is disclosed for coding input strings for a partial response 
channel to provide an output having a reliability determined by a 
preselectable coding gain. This method involves determining each 
frequency at which there is a zero in the transfer function of the 
partial response channel, and then encoding an input string into a 
binary code string having a power spectrum value of zero for each such 
frequency. A channel output sequence is generated responsively to 
transmission of the code string through the channel. The most probable 
sequence among those having a power spectrum value of zero is then 
calculated from the channel output sequence and decoded to provide the 
output.
