Inventor: UNKURI MATTI
IPC: D04H1/4209
Filed: 1988-07-04
Abstract: PCT No. PCT/FI87/00151 Sec. 371 Date May 8, 1989 Sec. 102(e) Date May 8, 1989 PCT Filed Nov. 11, 1987 PCT Pub. No. WO88/03509 PCT Pub. Date May 19, 1988.In a method for feeding out the primary web of a mineral wool web by means of a pendulum conveyor and to an arrangement of such a pendulum conveyor, an output is fed as close to the receiving conveyor as possible for the primary web to be rapidly fixed onto the underlying web. The conducting rollers at the output end, which rotate in the output direction, have a disturbing effect on such a close output. The front conducting roller in the direction of motion rotates in a direction having a lifting effect on the underlying web, which is negative, whereas the rear conducting roller rotates in a direction pressing down the web being fed out, which is advantageous for the output. Both conveyors of the pendulum conveyor are made vertically movable with regard to each other, the front conducting roller being situated higher and the rear conducting roller lower during the pendulum swing. The reversing mainly takes place in the end position of the pendulum swing. The reversing may take place momentarily or gradually during the entire pendulum motion.

Abstract: Process for the defoaming of aqueous dispersions of polymeric organic substances, particularly dispersions of binders, coating agents and adhesives, by addition of polyoxyalkylene/polysiloxane block copolymers, where the polyoxyalkylene/polysiloxane block copolymers used are those of the general formula
 R<1>O-A-[B-A-]mR<1>
 in which
 A is a polyoxyalkylene block of the average formula (CnH2nO-)y, in which n has a value of 2.8 to 4.0 and y has a value from 15 to 100,
 B is a polysiloxane block of the average formula 
<IMAGE>
 in which R<2> is identical or different and is an alkyl radical having 1 to 4 carbon atoms or a phenyl radical, however at least 90% of the R<2> radicals are methyl radicals and x has a value from 10 to 100,
 R<1> is identical or different and is a hydrogen or alkyl radical having 1 to 4 carbon atoms and
 m has a value from 4 to 20,
 in amounts of 0.01 to 2.0% by weight, relative to the dispersion to be defoamed. 
<??>The block copolymers to be used according to the invention show outstanding defoaming action, the particular advantage particularly lying in the fact that when the defoamed dispersions are applied to a flat substrate no defects in wetting occur.

Abstract: FEED FORWARD SPREAD SPECTRUM         SIGNAL PROCESSOR     ABSTRACT A communications receiver for a code division multiple access (CDMA) sat-ellite communication system in which a plurality of data carriers share the same band. A pilot carrier transmits a timing reference used by all receivers to acquire the clock used in timing the code generators, and used as a frequency and phase refer-ence for data detection. This receiver employs a digital signal processor that detects a spread pilot carrier and uses the phase noise on the pilot carrier to subtract the com-munication link phase noise from the data carriers, thus allowing communication at lower signal-to-noise ratios.

Title: Station-to-station full duplex communication in a token ring local area network
Inventor: YANG HENRY SHO-CHE
IPC: H04L12/433
Filed: 1991-01-21
Granted: 1995-10-17
Abstract: A technique for establishing and maintaining full duplex communication between two stations connect-ed to a token ring network, without dedicated connections.  In an auto-configuration full duplex mode of operation, each station ascertains whether there are only two active stations on the network and, if so, performs an exchange of frames with the other station to establish full duplex communication.  Once established, full duplex communication can proceed at a greater bandwidth than communication in a token ring network, and without latency delays and distance limitations associated with token ring networks.       Periodic checks are made by each station in full duplex communication, to ascertain if the other station is still participating or if any third station has become active. In either case, stations in the auto-configuration mode revert to token ring mode auto-matically. In a variant form of the invention, stations can operate in a fixed full duplex mode, in which the detection of tokens or third stations are merely reported and do not necessarily result in reversion to the token ring mode.
