Abstract: Ein Bestrahlungsgerät zur Aushärtung photopolymerisierbarer Zahnfüllungen in situ weist eine Lampe (10) auf, die ein konvergentes Lichtbündel mit einem Konvergenzwinkel (αE) von kleiner als etwa 30° bezüglich der optischen Achse erzeugt, sowie einen Lichtleiter (15), in dessen Eintrittsfläche (14) das Lichtbündel eingekoppelt wird. Der Lichtleiter (15) ist im wesentlichen durchgehend konisch mit von der Eintrittsfläche (14) zur Austrittsfläche (16) abnehmendem Durchmesser gestaltet und hat einen Brechungsindex von etwa √2. An der Austrittsfläche (16) findet dabei eine im wesentlichen halbkugelförmige Abstrahlung bei konstanter Strahldichte und hoher Bestrahlungsstärke statt, wodurch es möglich wird, auch schwierig zugängliche Zahnteile mit hoher Intensität zu be- bzw. durchstrahlen.

Abstract: The data storage apparatus has a storage plate (6), on which a light beam emitted from a laser light source (1) through a beam splitter (4) is focused with the aid of imaging optics (5). A light beam reflected by the storage plate (6) is blocked by the beam splitter (4) onto a detector arrangement (11). The latter comprises parallel strip-shaped detection surfaces (111, 112), the longitudinal axes (L) of which are arranged perpendicularly to the projection (62) of the tangent of an information track (61) on the storage plate (6) in the optical path of the reflected light beam. A focus error signal (FE) is formed as the difference signal between the sum of the output signals of the edge strips (112) on the one hand and of the middle strip (111) on the other hand. With the correct focus distance (d = f) of the imaging optics (5), this difference signal becomes zero if the width (b) of this middle strip is chosen such that the middle strip receives only half the radiant power. <IMAGE>

Abstract: A switched direct voltage converter comprises at least one semiconductor switch (S1) controlled by a control circuit (CC) via a switching input (SI), which semiconductor switch is formed with at least one pair of complementary field effect transistors (T1, T2) connected in a series arrangement (11) having through-connected voltage-controlled gate electrodes, in which a converted direct voltage (VS) is obtained by changing over the switch (S1) between supply voltage terminals (VT1, VT2). In the converter an input terminal (IT) for connection to a direct voltage supply source (V1) is connected via a coil (L) to a series junction point (SP) between the pair of the complementaryfield effecttransistors (T1, T2), and a converter output terminal (OT) is connected to one (VT1) of the supply voltage terminals (VT1, VT2), whilst a capacitor (C3) is present between the supply voltage terminals (VT1, VT2) and between input and output terminals (IT, OT), respectively. As a result, in the pair of complementary field effect transistors (T1, T2) the regular output has become an input (supply voltage connection) and a regular supply voltage terminal has become the output. The field effect transistor property of conducting current in two directions is utilised in the converter. A buffer-integrated circuit may be used with the interchanged connections in the converter.

Abstract: This invention relates to the use of scavengers containing peroxides for the removal of volatile sulphides, especially hydrogen sulphide present in feeds contaminated therewith. The feed is treated with a combination of hydrogen peroxide and an alkyl hydroperoxide at a pH of 6-10. The sulphides are thereby converted into inert, soluble sulphur compounds. The scavengers used are particularly suitable for treating crude oil contaminated with hydrogen sulphide.

Abstract: Dans un système de transmission de données bidirectionnelles, une station peut modifier sa puissance de transmission afin de maintenir constant le rapport signal-bruit dans chaque direction ou, dans un système utilisant une vitesse de données différentes dans chaque direction, afin de maintenir les deux rapports dans une relation fixe l'un par rapport à l'autre. Dans une séquence d'essai initiale, chaque station mesure l'écho de l'émetteur à partir de sa propre transmission, puis mesure le bruit provenant de la transmission de l'autre station. L'autre station effectue ensuite les mêmes mesures. Les donnés de bruit ainsi recueillies sont expédiées par les deux stations vers un circuit de commande situé dans l'une ou l'autre station, lequel calcule à partir des deux ensembles de données un réglage (par ex. une réduction) de la puissance à transmettre. L'une ou l'autre station réduit ensuite la puissance en fonction de ce calcul.

Abstract: In pulse-controlled power supply devices, the power dissipation at turn-off of the semiconductor switch (10) switching the primary winding (11) of a current transducer transformer (12) can be reduced by a capacitor (16) which is located in a circuit containing the series circuit of a reactor coil (17) and a diode (28) and is discharged in a further circuit containing a diode (19) and a primary winding (11) when the semiconductor switch (10) is turned off. Damaging overvoltages which occur across the series circuit of reactor coil and first diode (18) and are caused by inverse currents during the reverse recovery time of the first diode (18) are bypassed to the voltage source by means of a third diode (23) so that, as a result, the energy stored in the reactor coil (17) during the switching-over of the first diode (18) is returned to the voltage source and does not therefore have to be destroyed as power dissipation. The first and the third diode (18, 23) form a series circuit which is connected to the voltage source in the reverse direction. <IMAGE>

Abstract: This process is based on the principle of putting in suspension the product to be dried (cereal grains, food grains etc.) in a gaseous current which constitutes the hot drying fluid. According to the invention, there is alternation of drying stages and stages of cooling off of the material in the course of treatment, cooling off implying an absence of circulation of the drying fluid around the grains. An apparatus for carrying out this process comprises an envelope with a vertical axis, in which there is mounted at least one horizontal perforated plate (421a to 421c) which supports the fluidised bed, a blade (453) being capable of being displaced perpendicularly to the plate, two lateral hoppers (455, 456) with movable bottoms (455a to 456a) being associated with each plate, a blade (457, 458) being mounted in each hopper (455, 456).

Abstract: The circuit comprises an accumulator (A) charged through a rectifier (D1) from the network (P, N). Resistors (R3, R5) are traversed by a current delivered by the accumulator (A) as a result of the impedance of the network, and render the transistor (T1) conducting by virtue of the gate (NAND 2), even when the network voltage is absent. If the circuit is disconnected from the network, the transistor (T1) becomes non-conducting, thus automatically avoiding an undesired discharging of the accumulator (A). <IMAGE>

Abstract: The device, which is intended for use in the oxygenation of blood, comprises a bundle of hollow fibres (3) for oxygen exchange, intended to carry a blood flow within them and to be flowed over by an oxygen-carrying flow (4). The bundle of fibres (3) is inserted in a casing (1) provided with shaped end part (9) which is intended to be oriented upwardly, in use, and which forms a collecting chamber (8) for the oxygenated blood. This shaped end part (9) includes at least one connector (10) for discharging the blood, which is situated in a position generally out of alignment with the path of propagation of any gas bubbles present within the collection chamber. The blood outlet chamber (8) is therefore shaped so as to constitute a trap for any bubbles present in the oxygenated blood.

Abstract: The shoulder splinter (1) for correction of a habitual shoulder luxation consists of a single metal piece, at least part of which is designed with an open-cell structure in imitation of the spongiosa. The use of the shoulder splint dispenses with the hitherto conventional removal of a bone splinter from the tibia or the pelvic bone, and as a result of the primary mechanical stability of the shoulder splinter a significant reduction in the length of the post-operative treatment is achieved. The open-cell structure of at least part of the shoulder splinter (1) in imitation of the spongiosa permits a biological anchoring of the scapula into the splinter, as a result of which any loosening of the implant is prevented.
