Abstract: A communication network is proposed in which communication devices are connected via enabling devices to a central office. The enabling device is operated by a prepaid card (15) on which charge units are stored which are booked successively by charge pulses supplied from the central office. To ensure that premature withdrawal of the card from the enabling device (13) does not result in loss of a charge unit that cannot then be booked, immediately after insertion of the card in the enabling device and initiation of the call by a user of the communication device (12) an additional charge unit is booked from the prepaid card. If the call ends properly, this additional charge unit is credited back to the prepaid card. If the card is prematurely withdrawn this additional charge unit is retained. (Figure) <IMAGE>

Abstract: Crude oil and gas production wells, which no longer produce oil or gas utilizing conventional primary and secondary means of recovery, can be returned to production by treatment comprising addition of a non-aqueous solution of certain phosphate ester surfactants followed by successive treatment with water or a hydrocarbon. Increased production also can be obtained in low-producing oil and gas wells by similar treatment with certain phosphate ester surfactants. Subsequent to treatment of a producer well, the phosphate ester surfactant is forced into the formation utilizing water or a hydrocarbon and said surfactant is allowed to remain in the producing well, for an effective period of at least 12 hours. Thereafter, pumping and/or conventional fluid drive means are then utilized to recover oil or gas from the subterranean oil or gas formation.

Abstract: A method of treating natural or synthetic polyamide or cellulosic textiles comprises applying an effective amount of an arylating agent, preferably to the dyebath. The arylating agent may be of a formula Ar - (X - Y)<sub>"</sub> wherein Ar is an aromatic residue such as substituted or unsubstituted benzene or naphthalene ring; X is a bridging group such as - SO<sub>2</sub>, - CO - or - NH -; Y is a reactive group; and n is 1 to 3. The arylating agent reduces fibre damage of natural polyamide fibres during dyeing and proves the degree of dye fibre reaction in dyeing of polyamide and cellulosic textiles to improve wet fastness. Furthermore, on cellulosic textiles, wet and dry wrinkle recovery properties are improved as is the yield of reactive dye fixation. On keratinous fibres shrink resistant dye fixation. On keratinous fibres shrink resistant and moth resistant properties are improved also. Certain novel arylating compounds are disclosed also.

Abstract: A novel technique for stabilizing an electronic device (40), e.g. for stabilizing the bias current of a semiconductor laser at or near the lasing threshold of the device, comprises determining a derivative (in 100) of a variable characteristic of the device operation, e.g. the voltage across the laser, with re- spectto a parameter, e.g. the laser bias current. The derivative is determined by injecting one or more nonsinusoidal ac current (I TEST ) components into the laser, and phase-sensitively detecting the voltage changes at the ac frequencies. An error voltage obtained (by 101-104) from the derivative is used to control the bias current (in 105). The derivative extraction method can also be embodied in measurement apparatus, and is useful in other process control applications.
