Abstract: A plummer block for the arm of a Florentine blind with articulated arms, comprising a supporting block (2) which can be clamped to a supporting part, and a bearing block (4) which can tilt about a substantially horizontal axis into the descended position and on which an articulated arm (20) is mounted so as to be able to pivot about an axis aligned transversely to the tilt axis, the bearing block (4) and the supporting block (2) being coupled by a coupling rod (5) which permits and limits the tilting movement and has a thread (8) and adjusting nut (9), and a blocking slide (15) being coupled to the articulated arm (20), which blocking slide is displaceable transversely to the axis of the coupling rod (5) and blocks the same in the descended position. The technical problem is to construct the plummer block such that the functioning of the stop is independent of the blocking slide and that a blocking slide capable of being manufactured in a simple manner can be used. The adjusting nut (9) is constructed as a solid cylinder with thread passage in the radial direction. A cylindrical segment pan (35) is provided as a receptacle for the cylindrical face (32) of the adjusting nut (9). The blocking slide (15) touches the cylindrical face (37) of the adjusting nut (9) in the tilted position.

Abstract: The invention relates to a contact head (4) for a smoke projectile (1) having a propulsive charge chamber (8) for receiving a propulsive charge (17) and a firing charge (12) for the propulsive charge, having contact rings, lying externally on the circumference of the contact head (4) and electrically connected to the firing charge (12), having at least one blow-out opening (27), departing from the propulsive charge chamber (8), for the propulsive gas generated during combustion of the propulsive charge (17), and having a channel (30, 31), likewise departing from the propulsive charge chamber (8), for receiving a delay charge (32) for firing a smoke explosive (3), which is contained in a capsule (2) of the smoke projectile (1). In order to reduce the gas pressure inside the propulsive charge chamber (8) and on the other hand to limit the gas pressure inside a launcher reliably to permissible values, it is proposed according to the invention to divide the propulsive charge chamber (8) into a receiving space (16) for the propulsive charge (17) and a gas space (18), which are separated from each other by a plunger (19), which is mounted displaceably in the propulsive charge chamber (8) and is held in its initial position prior to firing the propulsive charge (16) against a predetermined rupture point. In this arrangement, the blow-out bore (27) branches off from the gas space (18). The plunger (19) also preferably has a through-bore (24), which connects the receiving space (16) and the gas space (18) to each other. The propulsive charge chamber (8) is designed as a separate component which can be pushed laterally into the contact head (4). <IMAGE>

Abstract: The object of the invention is to provide the sealing between a fixed casing (1) and a rotating shaft (3) passing through it in order to avoid any leakage of the substance contained in the casing (1). A collar (6) is fixed to the shaft (3) and carries a first friction ring (7). An annulus (18) inserted into the bore (2) for the passage of the shaft carries a second friction ring (16) by way of axial pressure means (28, 30). The annulus (18) has a stepped outer surface which engages with a stepped internal surface of the bore (2) such that the annulus is axially retained by the engagement of the shoulders opposite these two components. Angular locking means furthermore connect the annulus to the wall of the bore. The entire unit can thus be practically assembled and disassembled through the bore (2). <IMAGE>

Date Jun. 29, 1989.A method and apparatus for analyzing an electro-encephalogram (EEG) are described. EEGs from the left and right sides of the head are analyzed substantially simultaneously by detecting bursts of activity having amplitudes which exceed a threshold voltage. Each burst of activity is determined to have ended, i.e. the amplitude is below the threshold voltage, when it is followed by a quiescent interval having a duration of, for example, at least six seconds. The total time of all quiescent intervals occurring within a time period, e.g. ten minutes, is then calculated and displayed. The apparatus includes a digital computer for effecting statistical analysis of total times for many consecutive time periods. The computer may also be used in generating total times. A graphical output representing total times may be generated allowing rapid access of patient progress.

Abstract: A loudspeaker enclosure (1) operates in accordance with the acoustical band-pass principle and exhibits an external housing (2) in which an internal baffle board is provided with preferably two loudspeaker chassis attached thereto. The two loudspeakers (4, 4a) enclose a coupling volume between themselves and are located in chambers (5, 5a) which are sealed against one another. These chambers are connected to the external area via reflex openings (7, 7a). The loudspeaker chassis are acoustically connected in series and operate in phase acoustically. Having the same frequency response compared with a reference loudspeaker enclosure with one loudspeaker, this results in an approximate halving of the housing volume. In addition, distortions of the individual loudspeaker chassis are largely compensated for. The load-carrying capability of the loudspeaker enclosure is increased in accordance with the number of loudspeaker chassis, the use of two loudspeaker chassis resulting in approximately a doubling of the load-carrying capability. More than two loudspeaker chassis can also be arranged acoustically in series and operating in phase. <IMAGE>
