Abstract: An arrangement for controlling the operation of switch contacts includes means for providing a first signal indicating that operation of the switch contacts is required and timing means arranged to provide a second signal at a time indicative of a zero crossing of an alternating voltage being switched by the switch contacts. Delay means are arranged to delay the second signal to compensate forthe mechanical and/or electrical inertia of an operating means for the switch contacts. The operating means is then energised in response to the first and second signals so that operation of the switch contacts will occur at or near to a zero crossing of the alternating voltage.

Abstract: Es wird ein Verfahren zur Bestimmung der Aktivität des Kohlenstoffes in Ofenatmosphären o.dgl. beschrieben, bei dem das Partialdruckverhältnis des Sauerstoffes im Ofengas gegenüber einem Vergleichsgas mit Hilfe der von sauerstoffionenleitenden Feststoffzellen abgegebenen elektrischen Spannung festgestellt wird. Dabei wird als Vergleichsgas das Ofengas vorgesehen, das bei Ofentemperatur mit Kohlenstoff ins Boudouard-Gleichgewicht gebracht wird. Es wird außerdem dafür gesorgt, daß der Gasaustausch in der Vergleichsanordnung mit einer Zeitkonstanten von 1/10 der des Ofens stattfindet. Es wird dann der Vorteil erreicht, daß sich die Aktivität des Kohlenstoffes nach einer Formel berechnen oder eichen läßt, in der zwar die von den Feststoffzellen abgegebene elektrische Spannung und auch die absolute Temperatur enthalten ist, jedoch nicht der CO-Gehalt und auch nicht der Druck. Das neue Verfahren kann daher ohne Berücksichtigung des CO-Gehaltes in der Ofenatmosphäre arbeiten und vermeidet damit die Nachteile der bekannten Meßverfahren.

Abstract: Conventional incandescent filament lamps have an even number of filament sections so that the connections of the filament to the support wires are both at the same end of the bulb. It is found that in the horizontal position such bulbs burn out very quickly compared to their lifetime in the vertical position. Hence a lamp is provided with an odd number of filament sections (5) with the connections to the support wires (6, 7) being at opposite ends of the bulb. This significantly prolongs the lifetime of the bulb when in the horizontal position.
