Abstract: ABSTRACT OF THE DISCLOSURE   An improved process for the preparation of a fiber-reactive dye-stuff of the xanthylium-9-phenyl-2'-sulfonate series which contains in the 3-position an amino radical of the formula -NR1R2 in which R1 and R2 each are hydrogen or optionally substituted alkyl, and containing in 6-position an amino radical of the formula   in which R3 is hydrogen or alkyl, A is a mononuclear or binuclear aromatic ra-dical, m is 0, 1 or 2, n is 0 or 1 and p is 1 or 2, and in which .gamma. is a fiber-reactive group of the formula    (2) or                     (3) wherein R4 is hydrogen or alkyl, q is 0 or 1 and Z is hydroxy, sulfato, phos-phato, halogen or an acyloxy group, in which process 1 mol of a 3,6-dihalogeno-xanthylium-9-phenyl-2'-sulfonate compound is reacted step wise with at least 1 mol of each of two amino compounds corresponding to the required 3- and 6-substituents in the dyestuff, in a purely organic medium, the monocondensation product first formed being subsequently reacted, after neutralizing the acid formed, with the second amino compound, the reactions being carried out between about 70 and about 200°C in the presence of an acid-binding agent, and the di-amino-xanthylium compound thus formed is optionally esterified in the .beta.-hy-droxy-ethylsulfone group by means of a sulfatizing, a phosphorylating, a halo-genating or an acylating agent, the esterified dyestuff thus obtained being op-tionally converted into a dyestuff containing the group of formula (2) by treating it with an alkaline agent, characterized by carrying out the reactions mentioned without isolating any intermediate in a solvent containing carbon-amide groups, or in a polar aprotic solvent, whereby precipitation and drying of said diamino-xanthylium compound is no longer necessary.  This implies a considerable saving of time, the amounts of esterification agents are con-siderably reduced, and smaller reaction volumes can be used so that the space/time yield as well as the yields of dyestuffs are increased substan-tially.

Abstract: Abstract of the Disclosure A weatherseal is made by extruding a resin base with a relatively thick and generally flat support portion and a relatively thin portion U-shaped in cross section and joined to opposite side edge regions of the support portion and arching over one face surface of the support portion.  While the resin material is still plastic, a pressure is produced outside the U-shaped portion that is substantially lower than that inside such portion whereby to expand this portion away from the support portion and reduce the thickness of the wall of such U-shaped portion The resin material is then set with the U-shaped portion expanded.  Each side of the U-shaped portion is then cut off at a predetermined distance from the support portion to leave a pair of thin, spaced-apart, resilient fins extending away from the face surface of the support portion. A fibrous pile material is secured to the face surface of the support portion between the fins.

Abstract: TIME DIVISION MULTIPLE ACCESS SATELLITE COMMUNICATIONS SYSTEM               Abstract of the Disclosure A satellite communications system in which messages from a plurality of stations are received at a synchronous satellite in time multiplex without overlapping.  The system is so arranged that the apparatus to insure absence of time overlap in received messages at the satellite is relatively simple compared with the prior art closed-loop synchronizing systems.  In particular the guard time is controlled to be at least equal to the double hop propagation delay variation eliminating the need for accurate measurement of propagation delay.  Furthermore, as a result of the absence of critical propagation delay measurement, the acquisition process does not requires special purpose apparatus.

Abstract: FIELD OVERVOLTAGE PROTECTING APPARATUS       FOR SYNCHRONOUS MACHINE            Abstract of the Disclosure An apparatus for protecting a synchronous machine from a field overvoltage is disclosed.  The apparatus comprises a field excitation control circuit which is impressed with the armature voltage of the synchronous machine so as to provide a DC power supply for producing a DC output to excite the field winding of the synchronous machine, a first discharge circuit which is adapted to discharge the stored energy of the field winding when the synchronous machine is to be tripped under predeter-mined conditions, and a second discharge circuit for reducing the field voltage by allowing a field current to flow therethrough in response to generation of an overvoltage whose absolute value is higher than a pre-determined level, across the field winding.  The resistance of the second discharge circuit is selected to be higher than that of the first discharge circuit so that even in the presence of an overvoltage across the field winding, the overvoltage is suppressed by the second discharge circuit thereby to prevent frequent tripping of the synchronous machine due to overvoltage.
