Abstract: A multi-layer build-up system for floor coverings when using floor heating systems, particularly for laying ceramic floor coverings using the thin-bed method, has, on the underside, an essentially plate-shaped component for planar laying and for the accommodation of pipelines of a floor heating system. Component accommodation spaces for the pipelines are formed in the plate-shaped component and an uncoupling mat is disposed on the surface of the plate-shaped component. The uncoupling mat has an uncoupling layer on top of which an anchoring layer is disposed. The anchoring layer forms a structure element for a filler mass to be introduced in the top of the build-up system. The mass is plastic during processing and hardens afterwards. A reinforcement layer is disposed on top of and rigidly connected with the anchoring layer, at least in sections.

Abstract: The invention relates to a multi-layer decoupling system, in particular for the laying of ceramic paving according to a thin-bed method. Said system comprises a layered construction containing, from the base upwards, an anchoring fleece made of non-woven material, an anchorage layer that is configured from a lattice-type structural element and that is used to hold a filler material, which is to be incorporated into the upper face of the decoupling system and which is plastic during processing and subsequently cures, in addition to a reinforcement layer, which is fixed, at least in some sections, to the anchorage layer. This improves the load-bearing capacity of the decoupling system and the bonding properties of ceramic paving that is laid in a conventional manner on the decoupling system.

Abstract: The invention relates to a multi-layer decoupling and sealing system (1), in particular for the laying of ceramic paving (10) according to a thin-bed method (12). Said system comprises a layered construction containing, from the base upwards, a liquid-impermeable sealing layer (4), an anchorage layer (2, 3) that is configured from a lattice-type structural element and that is used to hold a filler material (12), which is to be incorporated into the upper face of the decoupling and sealing system (1) and which is plastic during processing and subsequently cures, in addition to a reinforcement layer (5), which is fixed, at least in some sections, to the anchorage layer (2, 3). This improves the load-bearing capacity of the decoupling and sealing system (1) and the bonding properties of ceramic paving (10) that is laid in a conventional manner on the decoupling and sealing system (1).

Abstract: The invention relates to a multi-layer sealing and drainage system (1), in particular for the laying of ceramic paving (10) according to a thin-bed method (12). Said system comprises a layered construction containing, from the base upwards, a drainage layer (3) that is configured from a first lattice-type structural element and comprises drainage regions (13) that are formed between the lattice structures of said element, a liquid-permeable nonwoven layer (6), an anchorage layer (2) that is configured from a second lattice-type structural element and that is used to hold a filler material (12), which is to be incorporated into the upper face of the sealing and drainage system (1) and which is plastic during processing and subsequently cures, in addition to a reinforcement layer (5), which is fixed, at least in some sections, to the anchorage layer (2). The system can also comprise a sealing layer below the drainage layer.

Abstract: A gland which is installed in the hole of a wall between two different atmospheres to prevent the leakage of a fluid from the one side to the other side of the wall along the outer sheath of an electric cable has a tubular metallic housing which is sealingly installed in the hole and into which the cable extends. The interior of the housing is filled with a hardened filler material which completely surrounds bare portions of conductors. Beads are formed on such bare portions. Sleeves are shrunk onto the bare portions of the conductors between the respective beads and insulators for the conductors. A tension reducing clamp surrounds the outer sheath of the cable in the housing. The aperture at one end of the housing contains an O-ring which is biased against the external surface of the outer sheath of the cable and against the surface surrounding the aperture by a second ring.

Abstract: An explosion-proof canned electric motor for use at elevated temperatures wherein the upper portion of the motor housing contains the stator windings and the rotor and is connected with a terminal box by means of a tubular heat barrier. The terminal box is disposed at a level below the upper housing portion and has an annular venting orifice in the lowermost part thereof so that condensate which accumulates in the housing flows toward the orifice. Such condensate is absorbed by a cake of diatomaceous earth or another suitable porous desiccant which is placed into the path of condensate flow toward the orifice. The desiccant also removes moisture from air which flows into the terminal box, and the desiccant is relieved of accumulated moisture during starting of the motor when the air in the housing expands as a result of heating and flows through the pores of the desiccant on its way into the orifice.

Abstract: A pump for circulating cooling and lubricating liquid is driven by a motor which comprises a central rotor; a tubular housing coaxially surrounding the rotor and normally filled by the cooling and lubricating liquid; and a stator coaxially surrounding this tubular housing. Heating elements are provided between the coil ends of the stator and the tubular housing for heating the liquid in this housing, during or after a shutdown of the motor, when the liquid is likely to have congealed or at least to have become viscous.
