Patent DE-3167312-D1 (DE)
Title: Process for operating an inverter with an intermediate dc link circuit supplying an electric synchronous motor
Inventor: BLUMNER CHRISTOPH DIPL ING
IPC: H02P25/02
Filed: 1981-08-06
Granted: 1985-01-03
Abstract: A method for operating a frequency converter of the type having an auxiliary commutating device for commutation at speeds which are lower than a machine-related minimum speed of operation. In a first speed range which begins at speed zero, the thyristors of a three-phase bridge of the inverter are commutated cyclically, as customary, six times per revolution of the machine. In a second speed range which is adjacent to the first speed range and below the machine-related minimum speed of operation, only every second commutation is executed. In embodiments of the invention wherein there is provided a third speed range which is adjacent to the second speed range and extending up to the machine-related minimum speed, only every third commutation is executed. In this manner, an auxiliary commutating device having a predetermined frequency limit can be utilized at speeds corresponding to two or three times the speed at which such an auxiliary commutating device could be used in prior art systems. Only slight drops in mean torque are experienced with the inventive method.

Title: Spring for a push button
Inventor: WILD PETER
IPC: F16F1/02
Filed: 1983-09-06
Granted: 1989-02-16
Abstract: In order to save space and manufacturing costs a pull-off effect for the operation of a key should be achieved by using a single spring. Thus the spring must have an arc-like force vs. displacement characteristic having a maximum of force about on half-way of the key stroke. This is achieved by a meander-like shaped spring (1) of flat material having two end loops (2, 3) of equal height and one middle loop (4) of about twice this height, all these loops lying within the same plane. The mounted spring is pretensioned in two directions being perpendicular to each other and lying in said plane, the operating force being applied to the top (7) of the middle loop.

Abstract: A sheet-like composite element for construction purposes. The longitudinal edges of the composite element is formed by U-shaped profiled edge members having legs that are directed toward one another and serve as supports for an inner and an outer cover layer, between which is disposed a core layer of hard foam. The edge members function as support elements, and have a cross-sectional area that conforms to the respective stress of the composite element. The hard foam core layer, which fills not only the space between the cover layers but also the hollow space of the profiled edge members, stabilizes the latter. Such a composite element permits free selection of the material and dimensions of the cover layers with a view toward the respective application of the composite element.

Title: Circuit arrangement for telecommunication exchanges, particularly telephone exchanges, comprising central control devices receiving information-processing orders from distributed control devices
Inventor: WEGMANN GERHARD
IPC: H04Q11/04
Filed: 1986-05-20
Granted: 1989-06-08
Abstract: Call-associated series of information-processing requests, accepted in decentralized switching facilities, are composed of initial switch identifiers which arrive first and of successor switch identifiers arrive following thereupon and are transmitted to a central switch mechanism from the switching facilities which are present in a greater plurality. A measuring device which continuously determines the loadability of a switching circuit periodically and continuously adjust the comparison standard of a counter, which only counts the initial switch identifiers in successfully following time intervals, perceives a pending overload situation for the switching circuit on the basis thereof and, in order to avoid the same, transmits non-acceptance data to the switching facilities in which, a portion of the received occupations are subjected to non-acceptance in accordance with accordingly stored non-acceptance rates. After a rest interval of the non-acceptance events due to a temporarily lower load, initialization of a renewed formation and transmission of the non-acceptance data occurs on the basis of the threshold pertaining to the number of initial switch identifiers incoming to the switching circuit per time unit, this threshold being continuously adjusted by way of measured loadability results which are derived in measuring time intervals which compensate unsteady low fluctuations from full load, actual load and actual numbers of initial switch identifiers per measuring time interval.
