Abstract: Bei Zahnringpumpen, bei denen das mit dem Hohlrad kämmende Ritzel nur einen Zahn weniger als das Hohlrad hat, sind die Hohlradzähne normalerweise durch Kreisbogen oder ähnliche Kurven begrenzt. Jeder Zahn des Ritzels (12) ist ständig mit einem Zahn des Hohlrades (10) im Eingriff. Die Erfindung verbessert die Eingriffsverhältnisse, die Dichtung und andere wesentliche Eigenschaften der Pumpe dadurch, daß die Zähne des Hohlrades angenäherte Trapezform mit konvex gewölbten Flanken und Köpfen aufweisen. Auf diese Weise sind die Zahnköpfe von Ritzel und Hohlrad miteinander nur noch in dichtendem, aber nicht mehr in treibendem Eingriff. Der treibende Eingriff zwischen Hohlrad und Ritzel wird ausschließlich zwischen den durch die Trapezform verhältnismäßig steilen Zahnflanken bewirkt.

Abstract: The invention relates to combatting of hostile targets by firing of explosive projectiles or missiles towards the target, which projectiles or missiles are provided with target tracking devices for automatic guidance of the projectile by reception and detection of electromagnetic radiation originating from the target. In order to improve the accuracy of fire at least one projectile or missile in a burst is provided with an illumination source which is activated by a target detector at the end of the projectile trajectory and then produces selective illumination of the target and its closest surroundings with radiation, for which the target tracking device in other projectiles is sensitive. In case of such selective illumination of a target area a correction of the projectile trajectory in following projectile(s) takes place in direction to the illuminated spot. Suitably all projectiles in a burst can be provided with an illumination source which is activated at the end of the trajectory as guidance aid for following projectiles. Hereby each projectile in the burst will have a more correct trajectory than the closest foregoing projectile and reliable hit will be ensured after a relatively small number of projectiles in the burst. The target tracking device can be of any known kind, for example operating with continuous scanning wave, radar pulses, IR, visible or laser light (Figure 1a).

Abstract: It has been proposed to base advanced Digital Switching networks on a modular array using Digital Switch Modules (DSM). It has been found, for large traffic handling Digital switching systems, that the cross-office delay encountered in multi-stage networks based on 8 x 8 Digital Switching Modules (DSM's) is unacceptably large. To maintain the flexibility provided by the multi-stage concepts a demultiplexing/mix- ing/remultiplexing stage (DMR) is introduced to replace intermediate DSM ranks. The DMR is used to provide a preset time/space switching function within the total trunking providing the availability of a controlled stage but without the control and delay penalties associated with a fully flexible DSM or the control and link blocking disadvantages associated with a pure space switch. The DMR effectively acts as a pre-programmed or counter driven DSM. By adjusting the degree of DMR function it is possible to provide a very wide range of switch sizes which uses a common organisation in the controlled switch stages. The operation of the DMR may be defined in conjunction with a mirror imaging correlation function to provide a constant switch loop delay for duplex connections.

Abstract: Combustible-gas detectors (of the kind in which a heatable wire filament constituting the detector element exhibits a change in resistance occasioned by the change in its temperature which occurs due to the oxidation of a combustible gas passing over it) usually embed the wire filament in a pellet of ceramic material coated with, or including therewithin, an oxidation catalyst. Unfortunately non-volatile residues - such as lead or silicone vapours - can poison the catalyst and/or obstruct the normal flow of gas to the element's surface, so reducing the sensitivity of the device. 
     The present invention allows the construction of a detector pellet having greater resistance to catalyst poisoning, especially by silicones, achieving this by building the pellet as a multilayered structure rather like an onion. The invention provides a combustible-gas detector element comprising a heatable wire filament (10; preferably a helical platinum wire) embedded in a pellet formed overall of an oxidation catalyst (preferably palladium) and a porous non-catalytic inert carrier therefor (preferably 75wt% alumina, 25wt% zeolite), wherein the pellet has a laminated, onion-like structure, and consists of a multiplicity (preferably 6 to 20) of concentric layers in which layers of carrier (11,13,15,17; preferably in pairs) alternate with layers of catalyst (12,14,16).
