Abstract: Une couche de lubrifiant sec est appliquée par procédé à tampon de transfert sur un piston (10) afin de réduire les contraintes associées à des pièces de moteur à mouvement alternatif. Un procédé permettant d'appliquer une telle couche à la jupe d'un piston est décrit. Des lubrifiants secs humidifiés sont dilués par des solvants volatiles pour produire un lubrifiant d'une consistance liquide et pour adapter de tels lubrifiants secs à un procédé de recouvrement par tampon de transfert. L'utilisation du procédé à tampon de transfert pour appliquer le lubrifiant sec humidifié sur le piston (10) permet une application précise et ciblée de tels lubrifiants sur des jupes de piston (12a et 12b). Ceci permet d'obtenir un piston enduit à un coût réduit dans la mesure où il n'est plus nécessaire d'effectuer le masquage de longue durée des pistons avant l'application d'un lubrifiant sec humidifié comme requis par le procédé de pulvérisation actuellement utilisé, et dans la mesure où l'on élimine les problèmes de gaspillage et de pollution associés à ce procédé.

Abstract: A braking circuit for braking a universal motor contains a changeover device for reversing the polarity between the field winding (6) and the armature (3) for the braking mode. In the braking mode, a series circuit consists of the armature (3), the field winding (6) and an electronic switch (35) via which the armature (3) is connected to the field winding (6) in a periodically repetitive manner. The kinetic energy of the armature (3) is essentially converted into heat, in a braking resistor (32), during braking. Suitable measures are adopted to ensure that the power which is converted by the braking resistor (32) falls less quickly than in proportion to the rotation speed, which makes it possible to manage with braking resistors of smaller dimensions for a predetermined braking time. <IMAGE>

Abstract: A compliant chamber is formed in a fluid line which connects a fluid supply (12) to a fluid receiver (14). The compliant chamber is alternately in fluid communication with the upstream (16) and downstream segments (18) of the fluid line. When the chamber communicates with the upstream segment (16) it receives and stores fluid at the head pressure. When the segment communicates with the downstream segment (18), a pressure equalization pulse occurs. A pressure sensor (22) in the downstream segment measures the pressure equalization pulse which is proportional to the head pressure. Processing the equalization pulse with the downstream fluid system resistance, the compliance of the compliant chamber and the equilibrium pressure results in a determination of the head pressure. Comparing the head pressure to thresholds permits determination of an occlusion or empty fluid supply. Where a peristaltic pump is used, the chamber is formed between the end fingers of the pump.

Abstract: The invention relates to a cylindrical combustion chamber housing of a gas turbine, in which the compressor air is supplied through a lateral admission elbow (2) in an arc-shape to the lower conical part of the combustion chamber housing, the perforated cone (5). Connected directly to the admission elbow (2) is the inlet core (1), in which the compressor air is guided around the perforated cone (5) on both sides. By means of the arrangement according to the invention, a tangential flow about a cone is transformed into an axial flow through the bores (7) in the perforated cone (5). The transformation of the flow direction of the compressor air is supported by radially arranged ribs (3). As a result, an optimum cooling of the entire mixer pipe (6) is achieved, with minimisation of the pressure loss in the air supply region (1, 2 and 5) and a simultaneous increase in efficiency of the gas turbine. <IMAGE>

Abstract: The coupling device (26), especially of a tractor, can be raised and lowered by control means. Control means of this type contain a sensor (38, 60) for recording an actual position value of the coupling device (26), an operating device (52, 54), adjustable by an operator, for setting a desired position value, an input switch (80) adjustable by an operator, and a control unit (50), by means of which a control of the coupling device (26) is carried out in dependence on the desired position value, on the actual position value and on the setting of the input switch (80), inasmuch as the input switch is in its working position. An unexpected raising or lowering of the coupling device (26) can be avoided as a result of a cancellation feature, by means of which control commands of the switch (80) are executed only when a further actuation of the switch (80) does not take place within a time interval. As a result, a response of the control system to an earlier intermittent actuation of the input switch (80) is suppressed, inasmuch as the input switch (80) is brought into a second position within a specific time interval after this actuation. Suitable as an input switch (80) is a spring-centred switch having at least three positions for raising, lowering and a neutral position which the switch (80) assumes as a result of the spring force, inasmuch as it is not actuated. A failure feature allows the possibility that, in the event of a fault, a raising or lowering of the coupling device (26) can be carried out by actuating the switch (80). <IMAGE>

Abstract: A chamber (10) is divided into a reaction zone (20) and a sublimation zone (30). A gaseous mixture (41) is supplied through a conduit (21) into the reaction zone (20) and heated by a heater (27). The components in the gaseous mixture (41) are reacted with each other to synthesize solid-phase SiC (42). The solid-phase SiC (42) is heated and evaporated by a heater (35), and condensed as a single crystal (43) on a seed crystal attached to a mount base (37). The mount base (37) is rotated and lowered in response to the growth of the SiC single crystal (43) by a rotary shaft (38). Since the SiC single crystal (43) grows from SiC synthesized by the vapor-phase reaction, the obtained product is of very high purity without the substantial inclusion of impurities. In addition, a single crystal having a large diameter or length can be obtained without restrictions imposed by the use of a crucible.

Abstract: The invention discloses a three-port filter being able to connect alternately a receiver and a transmitter to a common antenna in a radio system operating by the time division principle. The first signal path between the first and the third ports comprises all resonators (R1, R2, R3, R4). The second port is connected to one (e.g. R3) of the resonators in the first signal path, whereby a first subset (R1, R2) of resonators lies between the first and the second ports, and a second subset (R3, R4) of resonators forming the signal path between the second and the third ports lies between the second and the third ports. The resonators of either subset are switchable resonators, whose resonance frequencies can be shifted between two frequencies by an external control (Control). At the first control value of the control (Control) the resonators of this subset pass the RF-signal substantially without attenuation, and at the second control value they strongly attenuate said signal.
