Abstract: System for the bidirectional simultaneous transmission via a two-wire line for digital telphone, that uses a circuit of the adaptive kind for the cancellation of the noise caused in the receiver by the local transmitter owing to mismatchings along the line. A correction signal, correlated both to the symbols transmitted during this bit time and during a number of preceding ones, as well as to the line status, is subtracted from the signal to be sent to the receiver. 
     The signal emitted by the remote transmitter does not affect the correction signal as it is encoded by a line code having no dc component. One version of the circuit to be installed in the exchange (Figure 2) and another synchronized with the received signal, to be installed at the subscriber's (Figure 1), are provided.

Abstract: A method of producing a chromium yeast product having a high intracellular chromium content which is useful as a dietary chromium supplement is provided by treating an aqueous suspension of live yeast cells adjusted to an acidic pH in the range of 4 to about 7 with a water-soluble non-toxic chromium salt under essentially non-growth conditions for a period sufficient to permit the absorption of a significant amount of intracellular chromium ion by said yeast cells. The yeast cells so treated may be concentrated, washed free of extracellular chromium salts and dried or further grown by the addition of nutrients to the media, said growth period being of sufficient duration to reduce the intracellular chromium content of the yeast to a predetermined level followed by recovery, washing and drying of the chromium yeast as aforesaid.

Abstract: Risk of fracture of an optical fibre in an overhead stranded electric conductor 1 having an optical fibre loosely housed in an elongate compartment extending throughout the length of the conductor when the conductor is subjected to a tensile load greater than that which the optical fibre is designed to withstand is substantially reduced by supporting the stranded conductor from each of two opposite sides of a tower 2 by suspension means 3 incorporating a weak link 4 designed to fracture at a tensile load less than that which the optical fibre can withstand before fracturing. An excess length 6 of the stranded conductor extends between fittings 5 at which the suspension means 3 are secured to the conductor 1, is arranged sinuously down one side face of the tower and, where the standed conductor is an earth conductor, is detachably secured to the tower at spaced positions along its length by releasable clips 7. When the tensile load on the stranded conductor 1 increases to a value greater than that which the weak links 4 can withstand, a weak link will fracture and the excess length 6 of stranded conductor will be detached from the tower to reduce the load on the stranded conductor and thereby reduce risk of optical fibre fracture.
