Abstract: A cutter plate is provided for precision working, especially of holes, which is constructed as a symmetrical polygon with at least four corners and has at least one main cutting edge and one auxiliary cutting edge, as well as a projection which begins at the chip run-off surface of the cutting edges, whose sides serve as chip-guiding steps and whose boundary lines circumscribe a symmetrical polygon, whose shape corresponds to that of the cutter plate, and has smaller dimensions than the latter, so that, starting from the corner regions of the polygon, the width of the chip run-off surfaces decreases. The cutter plate is distinguished by the fact that each chip run-off surface has a plane shape and is inclined in the direction of its longitudinal extension by an angle in such a way that the narrowest region is at the greatest height and is arranged to be above the neighboring chip run-off surface, so that it can be manufactured very simply and economically by a grinding procedure. In this way, a very high accuracy of dimensions can be achieved. With this cutter plate, an optimum flow of chips and hence a superior surface quality, can be achieved. The shape of the cutter plate is so simple that several different cutter plates can be manufactured easily at favorable cost for various application purposes.

Abstract: Ceiling covers usually have a longitudinal support (2) which is provided with horizontal webs (4, 5), on which panels (3) are placed. In order to prevent the longitudinal supports bending or buckling under the effect of heat, it is necessary to arrange the longitudinal supports (2) at very short distances or to provide them with predetermined buckling points. This involves great outlay. It is envisaged that the longitudinal support (2) has two vertical webs (6, 7) which are parallel to one another, arranged at a distance from one another and interconnected, and which, in their lower end regions, respectively have at least one horizontal web (4, 5) for the placing of the panels (3), and that, between the webs (6, 7), a member (8) is arranged, which extends over the entire length of the longitudinal support (2) and is made of a non-combustible material. The fire-resistant ceiling cover can be used in the most varied embodiments and for the most different applications, for example for the satisfaction of the standards for fire protection class F 30.

Abstract: Low-water level washing machines are run at the start of the wash cycle at a low, moistening speed to improve the wetting of the load and are only switched to a higher, washing speed after the moistening phase. This means that moistening of the load is favoured only at the start of the wash cycle. The new washing method is intended to achieve good wetting and washing over the entire wash cycle. Good wetting and washing are achieved by setting the drum speed in a wash cycle during the on period of the drive motor in both directions of rotation first to a high speed (n1) for a predetermined period (t1) in the course of the on period and after expiration of this time period to a lower speed (n2). The method is suitable for drum washing machines which have control means for setting the speed of the drive motor and whose drums are equipped with means for scooping the wash liquor. <IMAGE>

Abstract: Dispositif à courroie croisée monté autour du pneu d'un véhicule automboile roulant sur une route enneigée, afin d'en empêcher le dérapage. Dans un dispositif à courroie croisée (1), un anneau externe (4) est supporté en rotation sur un anneau interne (3) fixé de manière amovible sur la roue (2) d'un véhicule automobile, et un ensemble de ressorts à lames déformables élastiquement (7) sont fixés radialement sur cet anneau externe, des courroies croisées (8) s'étendant à travers une surface de roulement (12a) d'un pneu étant reliées par une extrémité aux extrémités externes des ressorts à lames et par les autres extrémités à une sangle circonférentielle externe sans fin (9). Les courroies croisées peuvent passer de la position sur la surface de roulement à une position écartée de cette surface et vice-versa, grâce à la déformation élastique des ressorts à lames. Lorsque le diamètre du pneu varie à cause de la flexion de sa partie en contact avec le sol, qui se produit pendant le roulement, ou lorsque les courroies croisées se déplacent sur la surface de roulement dans le sens de la circonférence pendant le roulement, la variation du diamètre et le déplacement des courroies croisées sont compensés par la déformation élastique des ressorts à lames et par la rotation de l'anneau externe.

Abstract: A BiCMOS static random access memory is disclosed, where the sense amplifiers (10) each consist of a pair of bipolar transistors (42a, 42b) connected in emitter-coupled fashion. A pair of current sources (50a, 50b), such as MOS transistors, are connected between the bases of said bipolar transistors (42a, 42b) and ground, to provide additional pull-down current for the bit lines (BL, BL_). This additional pull-down current reduces the differential bit line voltage, improving the speed at which subsequent reads may be performed. Another embodiment uses a dummy column as a detection circuit (56), with the output of the dummy column controlling an operational amplifier (60), so that the operational amplifier (60) may bias the current source pair (50a, 50b) to control the pull-down current, and thus the differential bit line voltage. Another embodiment controls the current source pair (50a, 50b) responsive to the row address, so that the effects of series bit line resistance may be taken into account in establishing the desired pull-down current.
