Sound-insulating boards which are based on mineral fibers and thermoplastic binders and may or may not additionally contain fillers, flameproofing agents and water repellants contain, as the binder, from 4 to 20%, based on the weight of the mineral fibers, of polymers having a glass transition temperature of from 30 DEG to 80 DEG C. and consisting of not less than 60% by weight, based on the cop...

Liquid iodophors are provided containing as surface-active agent a product of the formula RO-(C3H6O)m-(C2H4O)n-CH2COOM, wherein RO is the residue of an alcohol of at least 8 carbon atoms or of an alkylphenol of at least 10 carbon atoms which is substantially free of olefinic unsaturation, m is a number having an average value of 0-10, n is a number having an average value of 2-20 and M is hydrogen...

Complexes containing a biologically active or functional compound or compounds are prepared by attaching or fixing a first compound, which may be a biologically active or functional compound, to a solid substrate under conditions such that the active site of said first compound is protected, thereupon derivatizing or combining said first compound with a derivatizing or modifying compound while sai...

An apparatus as disclosed for controlling the distribution of fibers in a fiber felt forming process, which comprises a guide duct through which a gas current with felt fibers entrained is directed. The gas passes through a perforated conveyor, which retains the fibers. The duct is caused to oscillate by a connecting rod affixed to the guide duct and a rotary element by universal joints at either ...

Contiguous metal plates are welded together without special edge preparation or bevelling e.g. of cut edges 13 from one side using a focussed high intensity laser beam 7. To ensure maintenance of welding conditions even when the plate edges are spaced apart by cutting imperfections or the like a wire 12 is fed to, or near, the beam focus 10 to intercept the beam and give rise to a plasma. This pla...

A 3-25 mm metal plate 22, 27, usually ferrous, is welded by a heavy-duty laser (5-25 kw) which melts through the plate and into a support member 24, 31 below to give a unitary weld. A gas supply to the laser beam focus is provided such that on the one hand the plasma is retained at least partially near the weld pool to give good energy transfer and on the other the plasma does not all escape.

The heat recovery installation (34) comprises at least one energy well (26). Pressure-producing devices (38,42) periodically impart an excess pressure to the well water in relation to that of the ground water in the surrounding earth. This produces a movement of water backwards and forwards between the earth and the well, and in turn an increase in energy exchange.(2)

Device comprises locking forks or raw locks fixed on the bottom plate which is attached to a tensioning arm. Two ropes can be locked together by being passed around the the forks. The arm is then rotated until the desired tension is achieved. The safety hook is then attached to the link which passes through the eye on the arm. (Provisional Basic previously advised in Week 8449)

A specially adapted device for the continuous laying of heat conduction tubes in the bottom sediment of lakes and other bodies of water features a floating and driveable work platform (1) on the water surface, which by means of a controllable support device (6, 8) carries at least one guiding wheel for hose (3) extending down into the bottom sediment. In order to produce a version of this device s...

A method for adding supplementary insulation to buildings, especially house walls, entails installation of studs (10) in the wall and application of slabs (19) of heat insulating material between the studs. The studs are fastened to the wall through use of forked brackets (12), which are fastened in the wall with a fastener (16) in such a way that legs (13, 14) project out from the wall. Into the ...
