Abstract: In the method for producing an underground structure, preferably a tunnel, with little earth cover under railway tracks or the like, the individual concreted structure or tunnel sections are advanced in the timed shifting process after their production. In order to prevent movements in the covering earth and the railway tracks during the digging-out of the earth at the local face and during the advancing of the tunnel sections, the rails, together with the sleepers and ballast foundation, are removed in sections. In a dug-out, flat pit is installed a covering reinforced concrete slab, onto which the ballast bed and the track skeleton are mounted again. The same procedure is followed in neighbouring areas and the reinforced concrete slab has further reinforced concrete slabs concreted onto it until the region through which a tunnel is to be driven is overlapped by a continuous concrete slab. After this concrete slab, which forms a securing means for the track, has been erected, the tunnel sections are advanced underneath said slab. <IMAGE>

Abstract: In a burner-heated apparatus with a heat exchanger (3) which is arranged in the waste gas guide (2) of the burner (1), which leads to a chimney (5) or similar waste gas take-off, and is flowed through by the waste gases of this burner (1), a portion, which can be selected as required, of the waste gases from the combustion chamber (8) is conducted directly into the chimney (5) or similar waste gas installation, in order that the temperature there is not allowed to fall below the dew point and as a result the formation of condensate is prevented. The size of this waste gas portion to be conducted off directly into the chimney (5) or similar can be defined from case to case taking the respective local conditions into consideration. The supply of uncooled waste gases can take place via a bypass guide (9) or the heat absorption capacity of the heat exchanger (3) can be reduced selectively. <IMAGE>

Abstract: A loudspeaker system is provided for installation in a space between a front panel and an enclosed area behind the front panel of a partition such as a wall, ceiling or floor fronting a listening area. Electroacoustical transducers are provided which have a two sided vibratory diaphragm driven by an electrical signal. An enclosure mounts the electroacoustical transducers such that one side of the vibratory diaphragm is in contact with air outside the enclosure between the front and rear panels of the parti­tion, with the enclosure being configured to substantially enclose and define a specific volume of air within the enclosure having a predefined acoustic compliance and which is in contact with the other side of the vibratory diaphragm of the electroacoustical transducers. The enclosure is mounted to the structural partition such that the enclosure extends into the space behind the front panel of the parti­tion so that the one side of the vibratory diaphragm con­tacts a volume of air outside the enclosure within the space behind the front panel of the partition. A passive radiator such as a port which has a specific acoustic mass is pro­vided for coupling the specific volume of air enclosed by the enclosure to the air outside the enclosure in the lis­tening area. A compression plate is provided spaced between the transducer diaphragm and the rear panel to isolate the rear panel from intense direct sound pressure from the transducer. With such an arrangement, the electroacoustical transducer itself and the enclosure are concealed within the structural partition, while the volume of air outside the enclosure means within the space behind the front panel of the partition is substantially acoustically isolated over the approximate frequency range of operation of the electroacoustical transducer from the volume of air outside the enclosure within the listening area.

Abstract: Apparatus for testing material (44) for thermally insulating pipes comprises a closed loop (20) of pipe (18) in a square configuration with an electric heater (26) mounted coaxially within it. Thermocouples (38) are attached to the pipe from the inside, and they and the heater are accessible via removable caps (24) at the corners of the square. The pipe is suspended from a support framework (12, 16) by rods (14) of low thermal conductivity welded (22) to the inside corners of the square. The insulating material is applied to the pipe, and additional thermocouples fixed to the exterior of the material. The heater is energised and the steady-state temperatures inside and outside the insulating material are measured. The configuration of the apparatus enables corrections for non-uniformity of heat loss and leakage through the rods to be readily made. Thus thermal conductivity values accurately representative of the performance of the insulating material in actual operation can be derived from the temperature measurements.

Abstract: Multi-layer sheet materials useful as protective laminates for application to substrates, such as photographic elements, which require the protection of an abrasion-resistant material, are comprised of a strippable carrier (10), an abrasion-­resistant layer (12) which overlies the carrier, a structural interlayer (14) which overlies the abrasion-­resistant layer, and an adhesive layer (16) which overlies the structural interlayer. The structural interlayer is very thin in relation to the thickness of the carrier, and is permanently bonded to one surface of the abrasion-resistant layer, whereas the carrier is releasably bonded to the other surface of the abrasion-resistant layer so as to permit it to be stripped away after it has served its purpose. A process for manufacturing the multi-layer sheet material comprises the steps of advancing the carrier in web form through a coating station at which it is coated with a layer of liquid composition that is curable to a solid form; laminating the structural interlayer to the coated surface of the carrier; curing the liquid layer in situ to a solid form to thereby form an abrasion-resistant layer; and applying an adhesive layer over the surface of the structural interlayer.
