The resinated and dyed and/or pigmented yarn may be produced by impregnating the warp yarn with a composition comprising the watersoluble resin, the catalyst and dye and subsequently dried at a temperature below 125C. Alternatively the curing catalyst may be applied subsequently. The dye may be a disperse dye or a mixture of dyes. The resin may be 1, 3-dimethylol-4, 5-dihydroxy-2-imidazolidone, a methylol melamine or a methylol urea. The catalyst may be zinc nitrate. The thermosetting resin may function as a size for the yarns so that no further sizing step is necessary in fabric formation. Polyvinyl alcohol or acetate may be added to the resin composition as an additional size. The composition may further comprise an acrylic (e.g. methylmethacrylate) resin softening agent and a surfactant. The yarn may be pure cotton, or a 50/50, 35/65 or 65/35 polyester/cotton or rayon blend. Preferably a major component of the yarn is a cellulosic fibre. Fabrics made with the warp yarns and resinated or unresinated filling yarns, may be heat cured to provide permanent press characteristics.

Title: Monitoring apparatus for detecting faults in the line circuits of time division telephone exchanges
IPC: H04M3/26
Filed: 1969-11-06
Abstract: 1287137 Automatic exchange systems SOC ITALIANA TELECOMUNICAZIONI SIEMENS SpA 6 Nov 1969 [14 Dec 1968] 54417/69 Heading H4K In a TDM exchange having, respective recirculating memories for storing the addresses of calling and called subscribers' speech switches, a common signalling highway and a common ringing bus, line circuits are monitored by injecting pulses of V.F. tone on to the ringing bus and noting the appearance of the tone on the speech and signal highways. Speech switch and signal switch failure is thus monitored as also is adjacent channel crosstalk and ringing switch capability.  As shown each group of subscribers U1-U24 has its own speech and signal highways Vah and Vsh which are connectible to common speech and signal highways Va and Vs. The speech gates I2, I7, the signal gates I1, I8 and the reed relay ringing switch I3 are all controlled by recirculating memories in central control UC. In order to test a line indicated by an address generator in UC, it is first determined that the ringing bus is free and that the line is not taking part in a connection, a signal A1 being produced if these things are so. A1 triggers on transistor Tr thereby bringing up relay R which causes 800 Hz tone generator GH to be connected to the ringing bus Vc. A1 also starts test device UP. Thereafter, during a clock phase #1 devoted to servicing, UP requests UC over lead M‹cs to close switch I3 so that tone may be injected into the line circuit AU1. Since gates I1, I2 (but not I7, I8) should be closed, the fault tone detectors Ric1 Ric2 and the crosstalk detector Ric3 (operable during succeeding phase #2) should produce no output. If this is so, the speech and signal gates I2, I1 are then closed in turn and the correct reception of tone is noted by the receivers. If any portion of the test results in a failure, an alarm is given over leads AI and an inhibitor UI passes an instruction to UC that the group gates I7, I8 pertaining to the faulty line must not be opened until the fault is cleared.
