Title: Compensating dowel for the connection of systematically tilted wooden framework bars
Inventor: SIEBERT ALBRECHT
IPC: E04B1/48
Filed: 1983-08-23
Abstract: The connection of wooden framework bars which are systematically inclined towards one another and intersect at any angle, has been possible hitherto by the provision of contact faces in the form of sloping saddle surfaces or by the arrangement of wooden packing pieces sloping in a plurality of directions. The application according to the invention of compensating dowel connections improves such structures with regard to the following points:   1) the problematic provision of saddle surfaces or wedges is dispensed with, as is their replacement by small-format drilled holes and milled reliefs; 2) shapes and sizes of the compensating dowels are selected in such a way that, for virtually all conceivable structures, only a few sizes of similarly shaped spacer dowels and insertion tools have to be kept in stock. Mass production and stock-keeping are therefore made simpler; 3) with the same shaping and corresponding selection of material, the fire-resistance classifications F-30-B and F-60-B can be achieved.

Title: Method for processing digital signal strings following transmission via a cable path
Inventor: BAUMGAERTL ULRICH
IPC: H04L25/03
Filed: 1984-03-27
Abstract: In a method for processing digital signal strings which are distorted by transmission via a cable path (1) and are affected by interference, the pulses are transformed irrespective of their curve shape into a string of linearly rising and linearly falling segments (equaliser 3), which then pass through a differentiator (4). Two phase-shifted pulse strings are derived from the output quantity of the differentiator (4) by means of a summing circuit (5) and an integrator (6), one of which serves as a reference curve. A delayed square-wave pulse of a timer (10) is added to the long pulses of the other pulse string to avoid premature zero passage in the summing circuit (5). A comparator (11) generates square-wave pulses by assessing values which fall above or below the reference curve. Errors in the phase angle and duration of the square-wave pulses are corrected in a flip-flop (13) with the addition of a clock signal (clock generator 11, 15). The described method may be used, for example, in the transmission of control signals in underground mining via telephone lines which are laid there. <IMAGE>

Title: Process for nucleating partly crystalline plastics and the use thereof
Inventor: KIRCH DIETMAR
IPC: B29B13/08
Filed: 1984-04-21
Abstract: Partly crystalline plastics such as, for example, polyethylene and polypropylene have extremely favourable properties which are known to a person skilled in the art. The crystalline structure, however, also has the occasionally somewhat problematical phenomenon that mouldings made of these polymers have, on account of the cooling conditions, a fine spherulitic structure externally and a coarse spherulitic structure internally. Because of the internal stresses which are also introduced, in the case of pipes, for example, an increased susceptibility to cracking results. In addition, a coarse spherulitic structure leads to reduced strengths, to a reduced electrical breakdown resistance and to an increased liquid diffusion. Now, for example, the addition of only 1 per cent by weight of a moderately neutron-irradiated polypropylene to conventional partly crystalline polypropylene leads, after processing, to such a fine structure that the spherulites are hardly detectable at 100 times enlargement. This is associated with technical advantages such as higher strength, higher impact strength, significantly greater transparency, earlier demouldability, increased film strength and increased modulus of elasticity. At the same time, the addition of neutron-irradiated PP increases the density. DSC (differential scanning calorimetry) measurements show that a slightly nucleated partly crystalline polypropylene (mixture containing 1 per cent by weight) according to the invention has a crystallisation temperature of, for example, 122 DEG C, by contrast to the normal ...
