IPC: G01R31/3183
Filed: 1970-05-14
Abstract: 1291522 Testing digital circuits INTERNATIONAL BUSINESS MACHINES CORP 14 May 1970 [19 May 1969] 23368/70 Heading G1U [Also in Division G4] A logic circuit 20, Fig. 2, is tested by applying successive combinations of input signals to both the circuit 20 to be tested and a reference logic circuit 30 and, for each input signal combination, sensing the amplitude of the voltage at each pin of the circuit under test relative to upper and lower thresholds and comparing the sensed amplitudes with the signals at the corresponding pins of the reference circuit.  Applying the input signals. A pseudo-random number generator 10 produces a random sequence of 48-bit numbers which are applied to gating circuits in a buffer 70. The gating circuits are controlled by a register 60 such that the output of the buffer 70 changes from one number produced by generator 10 to the next in 48 steps, only one bit changing at each step. The 48-bit output of buffer 70 is applied directly to the reference logic circuit 30 and, via a pulse shaper and synchronizer 80, to the logic circuit 20 under test. The buffer 70 also includes, for each bit, provision for over-riding the signal from the random number generator and forcing a '1' or a 'O' to be applied in series with a resistor to the relevant pin, enabling selected input pins to be maintained at a constant level and ensuring that the output pins are correctly loaded. Comparing the output signals, Fig. 4. The signal from each pin of the circuit under test is applied to two threshold circuits 92, 94. If the circuit under test is satisfactory, a '1' output will exceed the upper threshold and a 'O' output will be less than the lower threshold and thus the output should never be between the two. The outputs of the two threshold circuits are compared with the output of the corresponding terminal of the reference logic circuit 30 in a circuit 41-45 which produces an error signal whenever there is a discrepancy between the two logic circuits, or the output of the circuit under test lies between the two thresholds. Such an error signal, unless suppressed by the absence of a 'test on' signal on gate 47, causes an OR gate 49 to provide an error warning which stops further testing. Checking of the input pins ensures that open or short circuits are detected.

Title: Speech analysing system for determining base frequency - compares successively delayed versions of input signal with current value using comparator controlled by time switches
IPC: G10L25/90
Filed: 1970-12-18
Abstract: The system determines the base frequency of a speech signal which has been filtered so that the base frequency is no longer present. The signal is delayed by several successive time intervals and each time delayed signal compared with the momentary value of the input signal. The delay interval of the first delayed signal to differ from the input signal by less than a given amount is used as the period of the required base frequency. Pref. the system uses successive delay stages, the output of each of which is supplied in turn to a comparator (7) via switches (5), controlled by a clock generator (4). The comparator (7) is also coupled to the input (8) for the speech signal and causes a counter (6) indexed by the clock generator pulses to be halted when the difference between one of the delay stage outputs and the input signal is below a given threshold.

Patent JP-S6045258-B2 (JP)
IPC: C22B13/06
Filed: 1981-03-20
Abstract: Lead is separated from material containing lead sulfide, e.g. galena ore concentrate, by a substantially autogenous process involving establishing a pool of molten lead in a kettle, adding a metallic alkali metal, e.g. metallic sodium, to the molten lead in an amount sufficient to reduce the combined lead of the lead sulfide to metallic lead, adding the ore concentrate to the molten lead pool, and mixing together the metallic sodium, molten lead and ore concentrate. The sodium reacts rapidly and exothermically with the lead sulfide to reduce the combined lead of the lead sulfide to metallic lead and form sodium sulfide. The thus-liberated metallic lead reports in the molten lead pool, and a matte phase containing the sodium sulfide separates from the molten lead and forms on the surface of the molten lead pool. Lead sulfide from an excess of the ore concentrate, or other suitable added flux, which is usually added to the molten lead pool, serves to flux the sodium sulfide-containing matte phase to attain desired fluid and low melting characteristics of the matte phase. The process herein employs a kettle as the reactor, ordinarily the steel refining kettle of a lead refinery, is a low temperature process requiring temperatures above the melting point of lead but ordinarily not above 650 DEG  C., and does not discharge polluting SO2 into the atmosphere.

IPC: H04W36/04
Filed: 1992-03-13
Granted: 2001-05-21
Abstract: A handoff system where handoff requests are initiated not only by a home or serving base station, but also by neighboring base stations. As in conventional handoff, a serving base station may initiate a handoff request when the signal strength of one of its mobile stations falls below a predetermined threshold. In addition, neighboring base stations monitor the signal strength of neighboring mobile stations and request that a neighboring mobile station be handed off when that signal strength reaches a predetermined level. Thus, a handoff request may come from the serving base station because of a poor call connection or from a neighboring base station because of a possible strong call connection.
