Abstract: A piston-rack rotary actuator having a centre gear (16) on a shaft (13) and racks (24) which are in mesh with said gear at diametrically opposite points and which are connected to pistons (22) displaceable along respective cylinders (11) to obtain angular movement of said shaft about its rotational axis. In order to prevent piston slewing due to the separating force generated between the meshing teeth, that face of each rackbearing web (23) which is connected to the respective piston (22) is supported by the actuator body (10). Said gear (16) meshes with four racks (24) at equiangularly spaced points, said racks being connected to four respective pistons (22) each of which is displaceable in opposite directions which are normal to those in which the two adjacent pistons are displaceable. Said gear (16) extends across a cuboidal chamber (12) which, when all pistons have been fully displaced centripetally, also accommodates the four webs (23) arranged in a square.

Abstract: This invention relates to sensors for detecting a fault condition, e.g. excessive temperature or leakage of fluid, in a large apparatus, and to methods of using such devices. 
     The novel sensors comprise a conductor, an element composed of a conductive polymer whose resistivity increases sharply when a fault condition occurs, and a dielectric element which separates the conductor and conductive polymer element so that they form an electrical capacitor. The sensor is in the form of a sheet or cable whose capacitance is periodically measured. When a fault condition occurs, the conductive polymer element increases sharply in resistance in the region of the fault and reduces the capacitance of the sensor, thus signalling the occurrence (and preferably also the location) of the fault. Figure 1 shows a typical sensor in the form of a cable comprising a central conductor 10, a dielectric layer 12, a PTC layer 14 and on outer protective layer 16. 
     The invention is particularly useful for detecting localised overheating, e.g. in dryers for agricultural products, or leakage of a fluid, e.g. from a conduit.

Abstract: Bei einem Kolben aus einer Al-Si-Legierung mit einem mittleren linearen Korndurchmesser des eutektischen Siliziums von größer 3 µm für Verbrennungsmotoren mit einem hartoxidierten Boden wird das Gefüge des zu oxidierenden Grundmaterials in der zu oxidierenden Tiefe korngefeint auf einen mittleren linearen Korndurchmesser des eutektischen Siliziums von weniger als 3 µm, vorzugsweise weniger als 2,5 µm. Hierdurch wird die Erosionsbeständigkeit der Hartoxidschicht verbessert. Die Kornfeinung kann in den betreffenden Bereichen bereits beim Guß des Kolbens oder auch nachträglich durch Umschmelzen jener Bereiche noch vor dem Oxidieren erfolgen. Sind bei einer größeren Hartoxidoberfläche nur bestimmte lokal begrenzte Bereiche erosionsgefährdet, so reicht eine Kornfeinung begrenzt auf diese Bereiche aus.

Abstract: In derartigen Wicklungen treten innerhalb einzelner Scheibenspulen, insbesondere in von deren Randwindungen eingeschlossenen Ölzwickeln hohe elektrische Feldstärken auf. Zur Minderung dieser hohen elektrischen Feldstärken ist vorgeschlagen worden, im Wicklungseingangsbereich mindestens je zwei Windungen in jeder Scheibenspule am Innen- und Außenrand gegeneinander zusätzlich so zu isolieren, daß eine Wickelleiterkante durch diese Zusatzisolierung winkelförmig umfaßt ist und daß die Windungskapazität zwischen Windungen mit Normalisolierung höher ist als zwischen Windungen mit Zusatzisolierung.

Abstract: An aspirator jet suction pick-up device for handling and moving green sheets or other flexible materials employs a source of gas under positive pressure into the head with exhaust via a network of slots (32) disposed along the pick-up surface (12) of the head. As the gas exhausts through the ends of the slots via a manifold or plenum (22), an open groove (34) on the pick-up surface (12) entrains aspirated air causing a localized suction force. The suction force due to aspiration uniformly and stably holds a flexible sheet on the pick-up surface (12).
