Title: Alarm circuit

IPC: H04L1/20
Filed: 1970-11-26
Abstract: 1278877 Digital transmission system; alarm circuits SOC ITALIANA TELECOMUNICAZIONI SIEMENS SpA 26 Nov 1970 [27 Jan 1970] 56212/70 Heading H4P An alarm circuit has a lower threshold value circuit A resetting a first counter 1 and a higher valued threshold circuit B resetting a second counter 2 supplying a resetting signal to a third counter 3, outputs from counters 1, 3 being fed to a bi-stable flip-flop FF, the counters being stepped by clock pulses. The filling time of the first counter must be greater than the period of the carrier signal at its lowest frequency, the filling time of the third counter must be greater than that of the second counter and the filling time of the second counter must also be greater than the period of the carrier at its lowest frequency. The arrangement is only sensitive as to whether an incoming signal is above or below the threshold value and not to its actual magnitude. Preferably each counter has a plurality of stages and a decoder, the latter being variable to vary the effective capacity of the counter. When the carrier signal through input filter fr rises above a threshold level (SA), Fig. 2 (not shown), circuit A produces a resetting signal to counter 1 hence it does not produce a setting signal to flip-flop FF as long as the counter resetting signals arrive with sufficient frequency. If the frequency is insufficient, counter 1 is filled and produces a setting signal to bi-stable FF which activates an alarm. When circuit B produces an output signal, counter 2 is also repeatedly reset and does not produce an output as a result of which counter 3 produces an output and resets bi-stable FF so that the alarm signal ceases. When threshold circuit B does not produce an output, the counter 2 fills and repeatedly resets counter 3 so that this fails to reset the bi-stable FF. Bistable FF may be also of the clocked variety. In a simplification, counter 3 may be eliminated, the output signal of counter 2 directly resetting bi-stable FF. The arrangement will then be sensitive to noise. The arrangement is stated not to require calibration as the intervention times are defined by the clock pulse frequency and counter capacities which may be varied by adjustment of the decoders; also previous excursions of the carrier signal have no effect on a present operation.

Abstract: 1419320 Sampling liquids ULMAELEKTRO OY 28 Dec 1973 60059/73 Heading B8N [Also in Division F1] A device for sampling liquids from a channel or basin 4A comprises a sample measuring container 2 having a suction tube 4, a level indicator 3 and a valved sample delivering tube 5, a pump 1 connected to the measuring chamber, a control unit 7, and a multi-way valve 8 between the pump and measuring container, the arrangement being such that upon the starting of the pump, the delivery side of the pump is connected to the measuring chamber for a given period (e.g. 5 seconds) and after the period the intake side of the pump is connected to the measuring chamber. In operation upon closing the contact 10, the flexible delivery tube 5 is pinched closed by a clamp 6 and the four-way valve 8 is turned to permit the pressure created by the pump to build up in the measuring chamber and clear the suction tube 4. After a time interval the four-way valve 8 is automatically switched to permit the pump 1 to draw a sample through the suction tube 4 into the measuring container 2. When the sample rises it short-circuits the level measuring electrodes 3. The control unit 7 commands the four-way valve 8 to turn to permit the delivery side of the pump to be connected to the measuring container 2 for about five seconds. Subsequently, the pump 1 and delivery tube clamp 6 return to their rest position to permit the sample to drain out of the measuring container 2 through the delivery tube 5.

Apparatus for charging the battery of a portable appliance includes a control which may be selectively operated to vary the rate of charge. A motor in the appliance may be supplied either from the battery or from a  rectified A.C. source.  In the embodiment shown in Fig. 3, an electric shaver includes a motor MR, batteries B, a switch KS, and plug terminals ST 1 , ST 2 , ST 3  for connection to socket terminals CT 1 , CT 2 , CT 3  in a charger which comprises a mains transformer TR and a rectifier RE. To charge the batteries B fully over an extended period, the switch KS is left in the open position shown, and the transformer TR is connected to mains. Charging now takes place over conductors 30, 40 by way of resistor R<SP>1</SP> which limits the charging current to a level which allows charging to continue indefinitely. If it is required to charge the batteries quickly, e.g. for a single shave, a switch KSC on the charger is closed so that a lamp L and a resistor R 2  are now in parallel with the resistor R 1  and the overall resistance in the charging circuit is substantially reduced. The shaver may be used in isolation by closing contacts KS 2 , KS 3  so that the motor MR is energized from the batteries B, or alternatively the shaver may be operated directly from the mains using a cable connection between terminals ST 1 , ST 3  on the shaver and terminals CT 1 , CT 3  on the charger. The switch KS is moved to the position wherein contacts KS 1  and KS 3  are closed so that no connection is made to the batteries. In an alternative embodiment, Fig. 4 (not shown), the rate of charging is adjusted by changing the impedance of the circuit on the A.C. side of the rectifier.
