IPC: H03M1/00
Filed: 1988-12-19
Abstract: The digital-to-analog converter comprises 
- an input terminal (1) for receiving the digital input signal, 
- an output terminal (2) for supplying the analog output signal, 
- a current source circuit (3) having N current sources (I₁ to I N ) for generating N currents of substantially equal current intensity at N outputs (3.1 to 3N), 
- a combination circuit (4) having N inputs (4.1 to 4N) coupled to the N outputs of the current source circuit (3), an input (6) for receiving the digital input signal and an output (7). 
     For converting a digital signal D which is presented to the input terminal (1) during a time interval (Ta), this time interval is sub-divided into at least two sub-intervals (T d1 , T d2 ). 
     The combination circuit (4) is now adapted to combine the currents of current sources each time during a sub-interval in such a manner that the currents of each time a different combination of d from the N current sources are combined in each sub-interval located within the time interval. d is the decimal representation of the digital signal D.

Title: Regulateur secondaire combine
Inventor: OBERGFELL RAINER
IPC: H02M3/158
Filed: 1988-03-15
Abstract: Le régulateur est destiné à convertir une tension d'entrée non régulée (UE) en une tension continue de sortie régulée (UA), même lorsque la tension d'entrée (UE) est supérieure ou inférieure à la valeur de tension de sortie (UA) désirée. Il comprend, en plus du comparateur de la valeur de consigne et de la valeur effective (SIV), un équilibreur de courant (SNB) qui simule en tension capacitive le courant (JL) dans la bobine d'arrêt (L2) pendant la charge de cette bobine (L2). Un circuit d'attaque (TRS) commun fonctionne en source de courant constant pour les deux interrupteurs (V1, V2) à semi-conducteurs. Un contrôleur de la tension d'entrée (ESÜ) coupe le régulateur lorsque la tension d'entrée (UE) est trop basse. Un circuit de contrôle de la sortie (ASÜ) réduit la valeur de consigne du régulateur lorsque le seuil choisi n'est pas atteint.

Title: improved retrograde perfusion
Inventor: CALDERON REYNALDO
IPC: A61F2/958
Filed: 1988-08-08
Abstract: Tumours in the body of a patient are studied in situ by a monitor (12), such as computer assisted tomography, X-ray 
or the like, while optimal flow paths through the tumour area are established. A catheter (52) with a suction lumen 
(50) and 
an infusion lumen (25), with seals (22, 56) associated with each, is placed in the patient's vein near the tumor. Flow is 
then 
sealed in the vein with the infusion seal (56). A carrier medium dye is injected into the tumor at selected flow rates 
and dif­
ferential pressures. Flow of the dye through the tumor is observed on the monitor (12) to determine optimal retrograde 
per­
fusion paths through the tumor for the selected flow rates and differential pressures. Once the optimal perfusion paths 
are 
noted, microspheres with active ingredients, such as chemotherapy, can be selectively perfused through each of the paths 
in the tumor at desired flow rates, pressures and active ingredient dosages.

Abstract: L'appareil d'épuration du sang décrit comprend un système en cul-de-sac, dans lequel on laisse le sang du patient s'écouler à travers un ou plusieurs modules d'épuration (4), tels qu'un appareil d'hémodialyse, un filtre sanguin, une colonne de perfusion sanguine et un oxygénateur, jusqu'à ce qu'il atteigne un réservoir à paroi élastique (6), lequel est de préférence constitué par un sac sanguin standard. On inverse ensuite la direction d'écoulement du sang en exerçant une pression suffisante sur le sac (6), pour pousser le sang dans le sens inverse à travers le module d'épuration (4) jusqu'au système circulatoire du patient. Ainsi, étant donné que le réservoir a une capacité variable, puisqu'il est par exemple formé d'un matériau élastique, la capacité de l'appareil reste égale au volume du sang extra-corporel.

Abstract: A three-way valve comprises a valve body for controlling a flow and a counterflow. To control the flow, a cylindrical borehole into which a passage opens radially is provided in the valve body. The borehole and passage direct the flow. A closed pipe coaxial with the borehole and provided with a connection for the counterflow projects into the borehole. The wall of the closed pipe has at least one opening for the passage of the counterflow. An elastic collar fitted around the closed pipe seals the opening. The current is directed through an annular gap between the collar and the wall. When the counterflow is admitted, the collar expands in order to seal the passage and to direct the counterflow from the opening into the borehole.

Abstract: Arranged on a table top (1) are a compound slide rest (3), having a spindle head (5), and a laser light barrier (4). A workpiece (7), clamped in clamping jaws (6) of the spindle head (5), is rotatable about its axis of rotation and is displaceable in a Y-direction along its axis of rotation and in a X-direction across its axis of rotation. A strip-shaped laser beam (8) of the laser light barrier (4) is perpendicular to the said directions of displacement. Setting out from a measurement starting position, the workpiece (7) is displaced in Y-direction until it partially interrupts the strip-shaped laser beam (8). By rotation of the workpiece (7) about its axis of rotation, the polar coordinates of the workpiece are determined by the strip-shaped laser beam being covered at different places. After rotation about 360 DEG , the workpiece is displaced by a set distance in the Y-direction and the determination of the polar coordinates is repeated. The movements of the workpiece (7) can be controlled by means of a processor. The measured values are stored in an operating store and compared with input reference values. The maximum actual value of the diameter, the effective centre and the deviation of the centre from the axis of rotation (eccentricity) of the workpiece are calculated, stored and displayed in each case. <IMAGE>
