Title: Process for impregnating organic fibers
Inventor: HUHN KARL DR DIPL CHEM
IPC: D06M101/00
Filed: 1982-02-10
Granted: 1984-08-30
Abstract: Organic fibers are impregnated with an aqueous emulsion comprising (1) an organopolysiloxane containing diorganosiloxane units in which both organic radicals are monovalent hydrocarbon radicals, and further contains at least two monovalent SiC-bonded organic radicals with a basic nitrogen atom per molecule in which the SiC-bonded organic radicals with a basic nitrogen are present in monoorganosiloxane units, (2) an organopolysiloxane having at least 3 Si-bonded hydrogen atoms per molecule, (3) a catalyst for the condensation of Si-bonded condensable groups (4) emulsifiers, and (5) a diorganopolysiloxane containing an Si-bonded hydroxyl group in each of its terminal units and whose radicals are free of the basic nitrogen atom. If it is desired to impart hydrophobic properties to the impregnated organic fibers, then it is essential that (6) a trimethylsiloxy end-blocked diorganopolysiloxane be added to the aqueous emulsion. Moreover, as the amount of trimethylsiloxy end-blocked diorganopolysiloxane (6) is increased in the emulsion, the hydrophobic properties of the impregnated fibers increases.

IPC: H04M19/02

Granted: 1991-05-23
Abstract: Ring trip is detected when a telephone set which is being rung goes off-hook, through the use of a comparator in which the ringing signal superimposed on battery feed voltage is compared with a fixed reference voltage closer to ground than the battery feed voltage. Inasmuch as the duty cycle of the ringing signal with respect to the reference voltage is less than or equal to 50% under pre-trip (on-hook) conditions and will increase under trip (off-hook) condition, the comparator output is a square wave form of corresponding duty cycle. An up-down counter is caused to count up when the comparator output wave form is of one level and down when the comparator output wave form is of another level during each cycle of the ringing signal. The counter counts up during the portion of the comparator wave form which determines the duty cycle and down during the rest of the period of the cycle. Underflow and lack of underflow states of the counter respectively indicate nonring trip and ring trip conditions. Logic responsive to these conditions causes deactuation of a ringing relay to enable disconnection of the ringing signal from the ring lead going from the line circuit to the telephone set. The line circuit has a calling bridge which provides an output which is used to prevent the ringing relay from reoperating unless the telephone set remains on-hook after ring trip detection.

Abstract: In a catalytic reactor and a catalytic process, relative rotation is established between a honeycomb-like catalyst body (17) and feed and withdrawal means (11-14) for flushing and regenerating medium flows, and for the flow of material to be subjected to a catalysed reaction. In this manner, the different parts of the honeycomb-like body (17) will be successivle subjected to the different flows during each revolution. By adapting the rotational speed and the sector extent and also the gas throughflow rate for each individual zone to the flushing and regenerating medium flows and to the material flow, the time during which the catalyst is exposed to the different flows can be optimised for a given catalytic process.
