Abstract: Offenbart wird ein Balgengaszähler mit zwei Kammern (1, 2), die je eine bewegbare Wand enthalten, und einer gemeinsamen Welle (5), die zwei Exentertriebe ausweist, von denen der eine mit den Gestängen der bewegbaren Wände und der andere mit den Gestängen von zwei Schiebern (9) verbunden ist, welche die von den bewegbaren Wänden abgeteilten vier Teilkammern zyklisch mit einem Gaseinlaß und einem Gasauslaß verbinden, wobei die beiden Exentertriebe derart gegeneinander winkelversetzt sind, daß die Schieber (9) voreilen. Der mit den Schiebern verbundene Exentertrieb weist für jeden Schieber einen Kurvenscheibenantrieb auf, dessen auf der gemeinsamen Welle (5) sitzende und in eine langgestreckte Öffnung (7) des zugehörigen Gestänges eingreifende Kurvenscheibe (6) von der Kreisform abweicht. Damit wird die Öffnungscharakteristik der Schieber an die Bewegungscharakteristik der bewegbaren Wände angepaßt, was zu einer Verbesserung der Fehlerkurve des Balgengaszählers führt.

Abstract: The system is used for dialogue between data processing units with unbalanced inputs and/or outputs which are adapted to the balanced line network by means of transformers. These unbalanced inputs and/or outputs are provided with control devices, which determine the signal flow directions occurring in transmission and reception mode without affecting the transmitted or received signals themselves, accordingly controlling the switchover processes required for the operating mode concerned. An equalising circuit and a matching circuit with high return loss are also disposed in the reception path between the control device and the balanced line network, while a delay circuit is disposed in the transmission path between the control device and the balanced line network.

Abstract: An assembly of coaxial transmission lines (22) and coupling devices formed of closely spaced center conductors (32) of the coaxial lines, is formed within a planar configuration. The coupling devices are arranged either singly, or in pairs with one coupling device behind the other coupling device, to provide for a division of power between transmission lines and to provide for a crossing over of power from one transmission line to another transmission line. The transmission-line assembly is reciprocal in operation so that the singly arranged coupling devices may be employed for a distribution as well as for a combination of electromagnetic waves. Phase shifters may also be included to provide a desired phase relationship among waves outputted by various ones of the transmission lines. The transmission lines, the coupling devices and the phase shifters may all be fabricated in a parallel array within a common metallic plate (24) by automated milling machines for facile, accurate, and reproducible manufacture of the transmission-line assembly. The assembly including the matrix of coaxial lines for electromagnetic waves is readily structured to serve as a Butler matrix.

Abstract: The screw mill (1, 2) consists of two motor-driven screw conveyors (14, 15) mounted rotatably in a housing (17). The screw conveyors (14, 15) are divided into two sections. The first section is designed as an interacting screw conveyor pair lying in a common working chamber, while in the second section the screw conveyors (14, 15) lie in separate working chambers and form separate outputs (23). As a result, the occurrence of lateral forces is avoided on the one hand and, because of the absence of throttles in the working chambers, a high processing capacity is achieved on the other hand.

Abstract: A piezoelectric laminate comprises a piezoelectric layer and an insulating substrate layer rigidly bonded thereto. During poling, conditions are established under which a poling potential is established at the boundary of the layers which insures that a substantial part of the poling voltage is dropped across the piezoelectric layer. The poling voltage is maintained for a period greater than the time constant under the poling conditions of the material to which the poling voltage is applied. In one embodiment, the poling conditions are achieved by substantially enhancing the conductivity of the substrate layer relative to that of the piezoelectric layer. In a second embodiment, an intermediate bond layer is selectively switched from a non-conductive to a conductive state in response to a selected stimulus so as to form an electrode for facilitating the application of a poling field directly across the piezoelectric layer.
