IPC: H05B41/04
Filed: 1987-06-12
Abstract: A fluorescent tube lamp starter circuit for use with a lamp connected for a.c. energisation in series with an inductive ballast impedance, the starter circuit being connected between the cathodes of the lamp. The circuit includes a switch which undergoes a cycle of connecting together the cathodes of the lamp and then dis­connecting them several times in a half cycle of the supply. 
     The switch, which may be a thyristor having a high holding current or otherwise capable of being turned off by its gate, may be turned off when the current through the ballast impedance reaches a particular value or at regular intervals by an oscillator. 
     The pulsing of the lamp may be delayed to provide cathode preheating. Termination of the pulsing occurs after a preset time interval and when the lamp strikes. The detection of the lamp striking may be in response to a characteristic change in the voltage across the lamp.

Abstract: Die seismische Masse (5) ist mit der Montagebasis (1) durch einen Spannbolzen (6) verbunden. Dieser Spannbolzen ragt mit erheblichem Spiel durch eine Oeffnung des zwischen der Montagebasis (1) und der seismischen Masse (5) angeordneten piezoelektrischen Wandlers (2, 3) hindurch. Unter Massenträgheitskräften, welche quer zur Achse des Bolzens (6) auf die seismische Masse (5) wirken, treten Biegebeanspruchungen auf, welche sich auf einer Seite in einer Druckerhöhung und auf der andern Seite in einer Druckabnahme im Wandler auswirken. Der Wandler ist mit unterteilten Elektroden (3a, 3b) versehen, die den im Gegentakt auftretenden Druckbeanspruchungen entsprechend im Gegentakt angeordnet und geschaltet sind, so dass sich die Ladungsänderungen in den gegentaktartig angeordneten Elektroden bei Biegebeanspruchungen addieren. Aeussere Einflüsse, die sich gleichmässig auf den Wandler auswirken, werden dagegen kompensiert. Es wird hierbei mit einfachen Massnahmen Unempfindlichkeit gegen äussere Einflüsse ohne Einbusse an Messempfindlichkeit erreicht.

Abstract: The device comprises a plurality of pick-up members (5), preferably of the suction type, each of which is intended to take hold of a respective article in an array comprising rows arranged in at least one direction. The device includes a plurality of generally elongate and mutually parallel support members (4) which are intended to be oriented in the direction of the rows of articles in use. Each support member (4) carries an associated respective row of pick-up members (5) extending longitudinally of the member itself. Drive means (9) enable the distance between adjacent support members (4) to be varied so as to allow them to be adapted selectively to the spacing between the rows of articles. More particularly, this distance may be varied while the device is transferring the articles supported by the pick-up members (5) to a package so as to adapt the separation between the rows of articles to the dimensions of the package itself. Provision is made for the possibility of selectively varying the distance between the pick-up members (5) of each support member (4). 
     The preferred application is to the packaging of food products such as confectionery products.

Abstract: Method for operating a frequency relay and frequency relay for carrying out the method which, via measuring transform­ers, senses the frequency of an electric power network, de­termines the value of the frequency and delivers an output signal when the frequency thus determined drifts out of a permissible frequency range. Specific to the invention is the method of determining the currently prevailing frequency of the power network. The measurement signal (ŷ(t)) obtained from the network is transformed, after filtering (1) and digitizing (2), into an analytic model (4) in the form of a truncated Fourier series (y(t)), the coefficients of which are determined in a parameter estimator (3) which operates with a method of estimation (5) in accordance with the least squares method. Starting from model values, according to the invention a computation of the frequency can be carried out in a frequency estimator (6), the output signal of which, on the one hand, is returned as current frequency value to the parameter estimator and, on the other hand, constitutes a measure of the current frequency (ω̂) when determining the limits of permissible frequency variations.
