Abstract: The sawing apparatus comprises a rectangular workbench (1), a saw unit (2) with a sawblade (3), a machine frame (4) carrying the workbench (1), a fixed base frame (5) and a stop strip (6). The workbench (1) or the machine frame (4) is pivotable, together with the saw unit (2), about a vertical axis (7) relative to the fixed base frame (5), and the saw unit (2) is mounted in the machine frame (4) so as to be vertically adjustable relative to the workbench (1) and displaceable in the horizontal direction. In contrast, the stop strip (6) is directly connected to the base frame (5) via corresponding supporting rails (8 and 9). In order to have available an appropriate width when severing workpieces transversely, provision is made for the vertical axis of rotation (7) to be offset eccentrically towards the stop strip (6), in relation to the longitudinal extent of the workbench (1). However, this vertical axis of rotation passes through the centre of the base frame (5). In order to ensure a sufficiently stable support between the machine frame (4) and the base frame (5), supporting rings (10 and 11) lying against one another are provided coaxially to the vertical axis of rotation (7). The said supporting rings can also be used, in addition, for accurate angular adjustment and, for this purpose, are provided with a graduation and appropriate reference marks. <IMAGE>

Abstract: A regulated power supply includes switching transistor (36) for alternately driving the two halves of an input winding (42) of an output transformer (44), and an output circuit (52) connected to an output winding (46) of the transformer. A digital controller (10) generates pulse-width modulated control signals for controlling the duty cycles of the switching transistors in order to regulate the output voltage of the power supply. In order to correct for an imbalance condition in the transformer, the controller generates digital signals when the magnetizing current of the transformer reaches a threshold value, these signals serving to alter momentarily the pulse-width modulated control signals so as to set magnetizing current to a level in a sense opposite to the sense of the threshold value. Since the controller is digital in construction, integrated circuit chips may be used so that the power supply is of simple construction and of low cost.

Abstract: @ A vortex cleaner for separating fibre-liquid-suspensions, and in particular paper-pulp suspensions, into fractions, comprises an elongate vortex chamber (1) of circular cross-section, which over a part (3) of its length tapers towards its one end. At the wider end of the chamber there is provided a substantially tangentially directed inlet (4) for the suspension to be treated, and an axially directed outlet (6) for a lighter fraction of the treated suspension. At the narrower end of the chamber there is provided a second, axially directed outlet (7) for a heavier fraction of the treated suspension. The chamber is provided, within its narrowing part (3), with a plurality of baffles (9) which project radially into the chamber from the inner surface of the chamber wall, and which are inclined relative to the axial direction of the chamber substantially in concordance with the helical flow of suspension fed through the tangential inlet (7) and passing nearest the chamber wall towards the narrower end of the chamber, These baffles are mutually spaced apart when seen in both the axial and peripheral direction, in a manner such that the upstream end of a given baffle is located at a peripheral and/or axial distance from and downstream of the downstream end of the immediately preceding baffle. In this way, the baffles ensure that the heavier fraction is discharged through the reject outlet (7) at the narrower end of the chamber, so as to obviate the risk of the vortex cleaner being blocked, without impairing the fractionating process in the vortex cleaner at the same time.

Abstract: Procédé et appareil permettant, en transmission duplex d'informations numériques entre des abonnés connectés à des terminaux associés entre eux dans un réseau de télécommunication du type à multiplexage temporel dans lequel les informations sont transmises sous la forme de mots binaires par tranches de temps spécialement affectées, d'effectuer à l'aide d'un contrôle de parité, pendant les heures de trafic d'appels, un test de transfert pour vérifier qu'une connexion correcte a été établie après avoir rendu disponible un chemin de commutation. Le contrôle de transfert débute et la connexion est détectée dans la même station (terminal). Après avoir détecté une parité correcte, à l'aide d'un dispositif de contrôle de parité (M1) et d'un circuit de comparaison (OR), un bit de parité est généré avec une polarité intentionnellement incorrecte pour envoyer la ligne à la station suivante. La production d'une parité désirée s'effectue à l'aide d'un appareil comprenant un processeur local (MP), une mémoire de commande (CM), un compteur (PR) et ledit circuit de comparaison. Toutes les stations le long d'un chemin de commutation sont d'égale valeur et contiennent les mêmes dispositifs. Un processeur central affecte l'une des stations (TCT), au moment de l'établissement d'une connexion et la désigne comme station de commande pour le test de transfert de connexion. Le bit de commande avec la parité intentionnellement incorrecte est commuté directement au travers d'autres points de commutation restants et est bouclé dans le terminal de ligne (PCM2) où des informations provenant de l'abonné B sont reçues. La connexion de la boucle s'effectue à l'aide d'un circuit de contrôle de parité (M2) pour extraire le bit de parité côté terminal, et un autre circuit de contrôle de parité (M3) pour la formation de la boucle elle-même et renvoyer le bit de parité vers la station TCP. Un contrôle est effectué dans ce dernier pour savoir si c'est le bit de parité intentionnellement erroné qui est détecté, et si cela est le cas, la parité correcte est envoyée, après quoi l'on attend que cette parité correcte traverse le chemin ou circuit de commutation et qu'elle soit détectée de nouveau dans la station TCT. Après cette détection, un signal est envoyé au processeur central pour indiquer que le test de transfert de connexion est terminé, après quoi cette commande est interrompue et le contrôle normal de parité prend le relais, ce dernier ne faisant pas partie de l'invention.

Abstract: Electrical contact materials based on AgCdO with CdO as the main active component have proven to be particularly advantageous for low voltage switchgear in the power industry. However, when switching AgCdO contact materials, CdO, which is classified as toxic, can escape into the environment through burn-off. It is important, therefore, to keep the CdO content as low as possible in the contact material, or to exclude it completely. The contact material according to the invention is a sintered contact material consisting of AgSnO2 with at least two other metal oxide additives; namely, Bi2O3, CuO and optionally CdO. Relative to SnO2, these additives Bi2O3, CuO optionally CdO, amount quantitatively to a total maximum of 25 percent by volume of the total amount of oxide.

Abstract: @ A pair of small diameter optical fibers (12, 14) are arranged in a side-by-side configuration, the first fiber (12) providing a passive guide for pump light, and the second fiber (14) formed of a material, such as Nd:YAG which has amplifying properties at the signal frequency. The signal to be amplified propagates through the second fiber (14) resulting in amplification of the signal. The first fiber (12) is pumped from one or both ends, utilizing a cone shaped rod (50) which is optically coupled thereto. A plurality of pump light sources (60) are mounted on the end face (58) of the rod (50) to introduce collimated pump light into the large end (52) of the cone shaped rod (50). Total internal reflections on the cone walls compress the pump light to a small, fiber-size diameter end (54) for propagation through the pump fiber (12) and absorption by the active fiber (14). The pump light sources (60) are offset from the axis (72) of the rod (50) to excite high order modes in the pump fiber (12) to enhance absorption by the active fiber (14). The pump light sources (60) preferably comprise high power laser diodes (64) and collimating microlenses (62). By utilizing the cone-shaped rod (50) to couple light from the high power laser diodes (64) to the pump fiber (12), high pump power densities can be achieved, yielding increased amplification.
