Inventor: SCHUMACHER HINRICH
IPC: H04L12/00
Filed: 1988-03-10
Abstract: The arrangement is used to connect subscriber equipment via a manual switching installation (HVE) belonging to a data switching installation. A job storage arrangement (WF1) is assigned to this manual switching installation, in which jobs entailing the setting up of manually switched connections with dialling information can be recorded prior to processing and can be read out again for processing purposes in the order in which they were recorded. The jobs recorded in this call storage arrangement should be retrievable on the basis of different selection criteria. In the proposed arrangement, a job number and, if necessary, details specifying when the particular job is to be processed are also recorded for each job in the job storage arrangement (WF1). The job storage arrangement can be controlled from the manual switching installation (HVE) in such a way that the jobs can be read out, if necessary, depending on their direction or time of processing, in the order in which they were recorded. The arrangement can be used, for example, to set up connections to be switched manually between telex subscriber equipment. <IMAGE>

Abstract: A method for providing a nuclear magnetic reso­nance (NMR) angiographic image substantially only of moving spins associated with fluid flow in a living organism sample having a cardiac cycle at a cardiac rate, and immersed in a main static magnetic field, commences by nutating the spins by a preselected amount α less than 90°, in the initial part of each of a pair of imaging sequences. The repetition time interval T R  between sequential nutations occurs at a rate greater than the cardiac rate. After each nutation, a pair of alternating-polarity flow-encoding signal pulses are generated in a first magnetic field gradient impressed upon the sample, with each of the flow-encoding pulses in the first sequence of each pair having a polarity opposite to the polarity of the like-positioned flow-encoding pulse in the second sequence of each pair. The NMR response echo signal is acquired and the difference in the data from the pair of sequences is used to display at least one projection angiographic image.

IPC: F03B1/00
Filed: 1988-03-23
Abstract: There is disclosed a hydroturbine which exploits the potential energy of a water column of high pressure - changing it into the speed of the stream action of the flow over the rotor blades and by their rotating moment in­creases the speed of the jet by the press-back force pressing out the water flow of the turbine system. 
     The stator body (1) is a cylindrical cave (27) of oval shape in which is placed the shaft with the rotor on which is a comparting disc with, both sides equipped with blades. The blades are both on upper and lower side halfaxially positioned to the jet pipes (26). On the other side of the stator body, there is a half-axially positioned Bernulli pipe (19). 
     On the front side is the introductor (22), which closes by means of a hydro-closer (24) which continues by the introducing funnel (29). 
     The so disposed construction functions as follows: upon opening the hydro-closer, the potential energy of the water column changes over the introducing funnel and the jet-pipes (26) into high speed impact on the rotor's blades, turns them with high speed which by their turning is in­creased and presses out the water flow over the Bernulli pipe half-axially out of the system, achieving the constant work of the turbine. Lowering the hydro-closer, the fluid input steps, and therefore the turbine's work.

Abstract: The invention relates to a method for achieving elevated charging of an ignition capacitor in a capacitive type ignition system for internal combustion engines. 
     When starting a cold engine or when starting the engine under other conditions in which the battery capacity is low, activation of the engine starting motor will result in a drop in voltage in the electric system serving both the starting motor and the ignition system. The voltage drop in the electrical system will vary sinusoidally synchronously with the crankshaft rotation, owing to the fact that the starting motor will momentarily subject the electrical system to higher loads when the pistons are located adjacent their top-dead-centre position L in the compression stroke. 
     The method solves this problem, by delaying the re-charg­ing of the capacitor until a position H is reached in which the voltage drop in the electrical system has its lowest value.

Abstract: Le second niveau (10) d'une servosoupape régulatrice de débit à sécurité intégrée possède un boisseau (12) à cinq bossages monté coulissant dans un alésage (19) de corps. A zéro, les bossages terminaux (41, 45) sont pratiquement en position neutre par rapport aux fentes de pression d'alimentation (22, 26), le bossage médian (43) est pratiquement en position neutre par rapport à une paire de fentes de retour (23, 24), et les bossages régulateurs intermédiaires (42, 45) sont tous deux symétriquement en position non juxtaposée par rapport à leurs fentes régulatrices associées (29, 30). Des butées (34, 35) limitent le déplacement du boisseau dans chaque sens axial. Lorsque le boisseau est en position zéro ou bien dans l'une ou l'autre des positions extrêmes, l'écoulement souhaité par rapport aux fentes régulatrices est bloqué, et les fuites relatives sont régulées. On peut équilibrer ces écoulements de fuite de manière à obtenir un débit de fuite net pratiquement nul par rapport à chaque fente régulatrice. Dans une variante, on peut délibérément faire varier lesdits écoulements les uns par rapport aux autres en vue d'obtenir le débit de fuite net souhaité par rapport aux fentes régulatrices.

Abstract: In a two-armed cutter bar (10) for a lawnmower with a vertically rotating shaft, the cutters (14) are fastened at each of the two ends by means of a respective single fastening bolt (36). The end portions of the cutter bar (10) have conical rotary guides (24), into which fit correspondingly conical rotary guides (38) of the cutter carrier plates (32). This ensures centering and rotary guidance. A positive junction between a rib (46) of the cutter carrier plate (32) and a bead (20) of the cutter bar (10) makes a positive connection which is broken under excessive stress when a stone or the like is struck, the result of this being that the cutter (14) can rotate. The positive connection can be broken in this way in the elastic or plastic range if the parts engaging in one another are resilient or if, for example when an expansion bolt is used, the length of the bolt is increased when excessive load occurs. <IMAGE>
