Title: Edge guard means for a link belt and a link belt embodying such means
IPC: B65G15/56
Filed: 1981-12-03
Abstract: In order to protect the longitudinal edges (15) of a link belt (13) against damage or undue wear it is proposed to provide an edge guard means comprising a multiplicity of guard elements engaged with the coils (12) of the belt, the elements each comprising a body part for disposition adjacent the edge of the belt and a mounting means for engagement with a respective coil.

Title: Battery Feed Circuit
IPC: H04M19/00
Filed: 1982-02-12
Abstract: The battery feed circuit provides a balanced dc feed current (ITR) to a 2- wire telecommunications path. The dc current in each conductor is generated by bidirectional current sources (103, 104) each responsive to one of a complementary pair of first control signals (S1, S1) along with a second control signal (S2). The first control signals are generated by a feedback circuit (105) which monitor the differential mode voltage (VTR) across the path. To reduce power consumption, the first control signals are a nonlinear function of the differential mode voltage. Longitudinal balance is provided by the second control signal which varies the currents generated by each bidirectional current source by equal amounts. This second control signal is generated by a feedback circuit (109) which monitors the common mode voltage across the path. <IMAGE>

Title: Noise reduction in electronic measuring circuits
Inventor: BLACK IAN ALEXANDER
IPC: H03K5/1252
Filed: 1982-10-14
Abstract: A method of noise reduction in electronic measuring circuits is provided wherein two discrete signals (A,B) are separately established, each of which contains the same noise, and the signal P = A - NB is then established, where N is chosen to make P a minimum. The method is particularly useful in a method of pulse detection of the type wherein signals (A) and (B) obtained from two monitoring units (M1, M2) in series with respective components (CA,CB) are compared in a pulse discrimination device (P.D.S.) in order to detect the occurrence of out of phase pulses in the signals. In this event, increased detection sensitivity can be obtained by operating on the signals (A) and (B) by a difference amplifier arrangement (A3,A4) to establish input signals (P) and (Q) for the pulse detection system given by: P = (A - ??????B) and Q = (NB-???A> where ??? lies in the range of 0.5 to 1.0 and N is chosen to make the difference signal (A - NB) a minimum. <IMAGE>
