Title: Arrangement for use in detecting an amount of a flowing medium exceeding a preset quantily
IPC: G01F15/075
Filed: 1977-11-10
Abstract: The arrangement detects the number of measuring periods within a relatively long reading period, within which measuring periods a limit value corresponding to a predetermined quantity of a variable detected by an impulse meter is exceeded. Such arrangements are used for a fairer tariffing for consumers of electrical energy which temporarily have a very high demand. In this arrangement, the pulses output by the impulse meter are supplied to the input of a pulse counter (1) having an adjustable limit value which, when the limit value is not exceeded within a measuring period predetermined by the time base counter (5), is reset to its initial setting by this time base counter (5) but which, when the limit value is exceeded within the measuring period, increments a transgression counting mechanism (18) by one unit by outputting a transgression pulse, the pulse counter (1) and the time base counter (5) being reset to their initial setting. In the event of a mains voltage failure or inadmissible dropping of the mains voltage, wrong pulses can occur which increment the transgression counting mechanism (18). To prevent this from happening, a voltage monitoring device (23) is provided by means of which the electronics are stopped if the mains voltage drops below a particular value. <IMAGE>

Abstract: 1,006,260. Tunnel diode oscillator circuits. STANDARD TELEPHONES & CABLES Ltd. Dec. 21, 1962, No. 48323/62. Heading H3T. [Also in Division H2] An inverter oscillator comprises a chain of tunnel diodes connected across a D.C. supply in series with an inductor shunted by a capacitance. In Fig. 2, the supply E causes current to build up at a rate dependent upon the effective primary inductance of the transformer and the series resistance of the circuit. When the current exceeds the peak value of a tunnel diode the diode switches to its high voltage state causing the inductance of the transformer together with its parallel capacitance to ring. The second half-cycle will supplement the current through the diodes increasing it to a value at which a further diode will switch. This continues until all have switched whereupon, by a reverse process, all are successively restored to the low resistance state. The output may be rectified to provide a D.C. supply. The common points between the diodes may be connected by capacitors to taps on the transformer (Fig. 5, not shown) so that a diode, upon switching, switches a further diode by transformer action. The power supply may be a fuel cell, solar battery or electrolytic tank generator.

[Also in Division H2] A push-button controlled selector for a car radio comprises ferrite cores associated with tuning coils and mounted on plate 1 attached to non-rotatable nut 2 on screw 3 which carries gear-wheels 8, 9, meshing with wheels 10, 11 on stub shafts 12, 13. A motor 20 rotates shafts 12, 13 and eccentrically mounted shaft 17 about axis 14 to move the cores linearly. Five hypocyclic gear trains 21 are mounted on shaft 17, disc 22 and gears 25, 26, being rotated about axis 14 as shaft 17 rotates. In addition, gear 25 rotates in the opposite direction about its own axis as it engages fixed ring gear 29. The gear 26 rotates together with the gear 25 and drives ring gear 32 which is cut internally on annular member 33 rotatable within cylinder 30. Thus, the annular member 33 and disc 22 are rotated in the same direction about axis 14 as the shaft 17 is rotated. Clips 37, 36 are fitted on disc 22 and member 33 respectively, each clip having a slit in which are disposed brushes 42, 43, in contact with cylinder 30 and stirrup 34. The cylinder 30 has copper segments 46, 47 and 50, 51 embedded into it. If a selector is operated to select the third gear train 21, motor 20 is connected to stirrup 34 of that train, which is represented by closure of switch 61. If wiper 57 (representing brush 42) engages section 46, and wiper 58 (representing brush 43) engages section 50, the motor 20 is energized. The motor rotates the wipers 57, 58 in the clockwise direction, the wiper 57 reaches space 48. The wiper 57 remains within that space, without engaging sections 46, 47, when the wiper 58 is in contact with one of the sections 50 or 51, which are connected to resistors 64, 65. The clips 36, 37 are clamped to the brushes when the brushes are in the spaces 48, 52, the screw 3 being rotated by hand until the radio is tuned to a required station. The clamp may then be released leaving the brushes still in the spaces. If, after subsequent selection of an alternative station, the same gear train 21 is again selected, the motor will drive the screw 3 until the brushes re-enter the spaces whereupon the radio will be tuned to the station previously selected by hand.
