Abstract: The vacuum induction furnace according to the invention contains a hermetically sealable chamber (1), surrounded by an inductor (7), with a crucible (2) accommodated therein. The side surface of the crucible (2) is formed by cooled metal sections (10) which are separated in relation to one another by insulating intermediate layers (11). In the lower part of the crucible (2), a cooled bottom-pouring plate (3) is arranged, which is connected to a mechanism (6) for its perpendicular movement to and fro in relation to the crucible (2). The inner surface of the crucible (2) is made in stages with a diameter which decreases in the direction of the bottom-pouring plate (3). Such a design of the crucible (2) makes it possible to produce bars of different diameter in the same crucible (2).

Abstract: Die Erfindung betrifft ein Verfahren zur Herstellung einer rohrförmigen Nockenwelle, bei dem auf einer vorgefertigten rohrförmigen Welle einzelne Nocken nachträglich aufgebracht werden. Derartige Verfahren gewinnen angesichts der Vielventiltechnik im Kraftfahrzeugbau zunehmend an Bedeutung gegenüber den bis heute noch überwiegend angewandten Verfahren des Gießens und anschließenden Drehens und Schleifens von Nockenwellen. Im Unterschied zu bekannten Verfahren, nach denen fertige Nocken mittels verschiedener Techniken auf eine vorgefertigte rohrförmige Welle aufgebracht werden, wird gemäß Erfindung pulverförmiges Nockenmaterial direkt auf die vorgefertigte rohrförmige Welle aufgepreßt und aufgesintert. Bei diesem Verfahren ist die Verwendung von nur einmal verwertbaren Preßhüllen wesentlich, welche vorzugsweise nach dem Kunststoff-Blasformverfahren hergestellt werden. Neben der Wirtschaftlichkeit besitzt dieses Verfahren die Vorteile größerer Gestaltungsmöglichkeit hinsichtlich Formgebung und Werkstoff-Auswahl.

Abstract: The filter is intended to filter an incoming digital signal (SN) having a variable rate (Fb) which can attain several Mbit/s, despite the maximum frequency of operation of a digital-analogue converter in the modulator. The oversampling factor FA is essentially inversely proportional to the variable rate (Fb) in order for the sampling frequency (Fe) applied to the converter to be essentially constant. Logic means (12, 15, 16) cyclically produce FA sample numbers in response to each incoming bit. One out of several sample-address sub- memories (14), equal in number to the possible oversampling factors, is selected by the chosen factor (FA) and read cyclically by the sample numbers. The bits of the incoming signal (SN) are converted into respective symbol words (TB) each comprising one bit from the incoming signal and bits neighbouring this bit. One out of the several sample sub-memories (13), which are associated with the possible symbol words and have each stored pulse responses from the said filter for the possible factors, is selected by the respective symbol word in order to be read by the addresses read from the address sub-memory selected by the chosen factor so as to furnish FA digital samples (EC). The modulator furthermore comprises a non-switchable, period, low-pass filter. <IMAGE>

Dans chacune des stations terminales, les informations relatives aux erreurs de transmission sont détectées, et les seconds mots transmis par la station terminale et reçus sans erreur de transmission par la station centrale sont mémorisés. Les premiers mots reçus sont décryptés dans la station terminale en fonction des informations d'erreur de transmission détectées et des seconds mots mémorisés.

Abstract: A bicycle derailleur gear shifting system having a rotatable handgrip actuator cam (74) which is coupled with derailleur shifting mechanism (54) through a control cable system (60, 64) so as to control the derailleur mechanism (56, 58). Separate actuator cams are associated with the front and rear derailleurs. For the down-shifting direction, at least the rear derailleur cam is configured so as to substantially compensate for increasing force of the derailleur return spring (208) so as to substantially compensate for numerous cumulative lost motions in the derailleur shifting mechanism (54) and cable system (60, 64), and for chain gap variations; and so as to overshift the chain a sufficient amount beyond the destination freewheel sprocket (54a) so that the chain will approach the destination sprocket (#5) in the same direction as it would in the up-shift direction, but not sufficient to cause a double shift, or derailling from the #1 sprocket. A front derailleur cam is configured to provide fine-tuning for ''cross-over'' riding.

Abstract: The work-space envelope of a conventional articulate multiple-shaft robot is limited to within ±180° with respect to all shafts due to the construction of the robot. The expansion of the work-space envelope of a robot has come to be demanded recently, and the construction of and a control method for a robot has been improved accordingly, so that this envelope has been expanded to up to ±360° . However, it is difficult in some cases to apply such a control method to a robot having a shaft which is turned not less than ±360 °, and the robot cannot be operated in some cases. Therefore, according to the present invention, in order that a signal representative of a position to which a shaft has been turned is indicative of an angle within the range of ±360° with respect to a reference position of the same shaft, a signal representative of the number of revolutions which is obtained by multiplying the number of revolutions of the mentioned shaft by an integer is added to or subtracted from the above actual position signal in accordance with a plus or minus sign thereof, and a signal representative of the result of this addition or subtraction is used as a signal representative of a position of rotation of the shaft at the time of starting of a posture control operation. This corrected link angle becomes less than ±360 °. Therefore, if this control method is employed, a smooth interpolation operation can be carried out. Accordingly, the workspace envelope of an articulate multiple-shaft robot can be expanded.

Abstract: An apparatus for use in measuring fetal blood flow characteristics. The apparatus includes a non-invasive pulse oximetry probe that is inserted into the uterus between the fetus and the uterine wall. The probe is deformable and is positively attached to the fetal tissue surface using a vacuum pump which causes the probe to deform from a pre-set curvature to the curvature of the fetal tissue surface and to form a gasket-type seal with the fetal tissue surface. The probe is manually inserted into the uterus using a curved insertion tool, and is shaped to fit through a slightly dilated cervix. In a preferred embodiment, the probe includes fetal and maternal ECG sensors and additional sensing devices, and is provided with apparatus for improving the efficiency of the pulse oximetry optics.
