In this case the cavity (3 )is filled by means of at least one resilient filling material or body, resilient at least as viewed in the radial direction of the rope (1), and which, when the rope (1) is pulled over an edge and with a high tensile force for example, results in a considerable momentary flattening of the cross-section of the rope when pulled over the edge and thus a considerably wider support of the rope (1) on such an edge. In addition, the rope core (2) is surrounded by a rope sheathing (4) provided with a protective layer (5) impervious to particles of dirt.

The sealing mechanism comprises means for expanding the diameter of the sealing ring against said spring force.

Abstract: Optical smoke detectors such as extinction smoke detectors and scattered-light smoke detectors include a radiation source, a radiation detector or receiver, and a measurement volume which is in communication with ambient atmosphere and which is traversed by a light path from the radiation source to the radiation receiver. For compactness and simplicity, such an optical smoke detector is provided with a planar-optical element in the optical path. Suitable as planar-optical elements are diffractive elements, e.g., holographic-optical elements (HOE), and micro-Fresnel elements (MFE), e.g., micro-Fresnel reflectors (MFR).

Abstract: An infrared intrusion detector uses infrared-sensitive sensors with pyroelectric sensor elements for detecting infrared radiation from a spatial region to be monitored. Infrared radiation passes through an entrance window and reaches the sensor elements via focusing mirrors. Extraneous radiation, outside the useful radiation band, is eliminated by filtering at the entrance window and by an optical transmission filter, and by scattering at suitable rough surfaces of the focusing mirrors. As a result, the infrared intrusion detector is less sensitive to extraneous radiation and less likely to produce false alarms.

Abstract: Apparatuses for the infeed of cartridges predominantly of two different types of ammunition from conveying devices to a Gatling-type gun or weapon system, can be constructed such that first and second transport devices, a third device and the Gatling-type gun can be simultaneously driven if there are provided storage devices for the intermediate storage of the empty cases during reverse clearing following a firing burst. These storage devices are operatively associated with conveying devices from which the Gatling-type gun has delivered ammunition thereto by the first and second transport devices. The conveying devices, which deliver cartridges from ammunition magazines, can be selectively driven. There is prevented transport of empty cases during reverse clearing by the Gatling-type gun and there is attained the result that the Gatling-type gun is free of empty cases prior to accomplishing a new firing burst.

Abstract: Pre-rotational swirl controller for rotary pumps having a flow duct enclosed by a casing and a plurality of guide vanes located substantially radially within it. Each of these has two bearings, i.e. one on a hub located centrally and one on a trunnion which passes through the casing and which is also acted upon by an adjusting device. The guide vanes can be radially assembled through the casing because, for each guide vane, there is a removal slot which is closed by a cap which carries the seal and the bearing for the guide-vane trunnion, these being designed so as to be tolerant of alignment errors. A self-locking setting gear with a large transmission ratio and a through drive shaft is provided for the adjustment.

Abstract: Apparatuses for the infeed of cartridges predominantly of two different types of ammunition to a Gatling-type gun or weapon system, can be stationarily installed if there are employed, apart from two transport devices, storage devices for the intermediate storage of the empty cases or spent cartridges during the reverse clearing operation following a firing burst. There is prevented transport of empty cases or spent cartridges during reverse clearing by the Gatling-type gun and there is attained the result that the Gatling-type gun is free of empty cases prior to accomplishing a new firing burst. Additionally, it is possible to fire cartridges or ammunition rounds of one type of ammunition without interruption from two ammunition magazines.
