Patent DE-3102692-A1 (DE)
Title: Partial screen for a road for the purposes of noise protection
IPC: E01F8/00
Filed: 1981-01-28
Abstract: Recently, for noise protection reasons, partial screens, comprising lateral walls and a cover provided with orifices for the purposes of natural illumination and ventilation, have often been arranged along roads. In the case of a known design, the orifices are provided right across the edge strips and are interspersed with sound-absorbing, plane elements arranged parallel to the roadway axis in such a manner that no sound radiation can get out directly. According to the invention, the central planes of the element of this design, as illustrated in the drawing, are to be arranged about a constant angle alpha  of 15 DEG  to 25 DEG  inclined towards the vertical to the centre of the roadway, in which arrangement the ratio between the element height h in the direction of inclination and distance a from the adjacent element perpendicular to the element plane must be at least three. This ensures that, as well as a high level of noise protection, a good, uniform illumination of the roadway is achieved in daylight without disturbing direct sunlight. <IMAGE>

Patent DE-3128531-A1 (DE)
Title: Selector, especially for telephone systems
Inventor: LENZ KURT
IPC: H01H67/08
Filed: 1981-07-18
Abstract: As a result of the large mass of their setting device which is to be moved and braked at a high setting speed, a large amount of force has to be exerted and the setting reliability is low in the case of selectors having 100 or more selector outputs. The multiple cabling (wiring) of their selector outputs is costly (ribbon cable) and the particular precision of the electromechanical component is costly in terms of maintenance. The invention relates to the increase in the number of selector outputs of the selector according to Patent 2416228 by means of relays per decade, decade relays 1 ... 0, in the flat-bank matrix. As a result of low mass of the selector setting device to be moved, since this requires only 12 selector outputs, the setting speed of the selector according to the invention, which is provided with 120 selector outputs and is used as a line selector, group selector, line finder (line switch), route selector etc., is very high. The selector which is provided with the flat-bank matrix is, according to the invention, conductively connected (Figures 1-6) inside the flat-bank matrix to the relays per decade, decade relays 1 ... 0. No solder points or wire-wrap connections are therefore required. The flat-bank matrix is ideally suited, according to the invention, for fitting (incorporation) of the decade relays 1 ... 0 (Figures 3, 4, 5). <IMAGE>

Patent DE-3140852-A1 (DE)
Title: Speed regulating arrangement
Inventor: CAP HEINRICH ING GRAD
IPC: H02P7/288
Filed: 1981-10-14
Abstract: The circuit according to the main application is further improved by a simple measure. A discharge resistor (183) is connected in parallel with the capacitor (83) from which a voltage characterising the ACTUAL rotation speed is picked off. On the one hand, this improves the regulation behaviour and, on the other hand, it prevents excessive motor rotation speeds, since it reliably discharges the capacitor (83) in the event of excessive rotation speeds and hence removes power from the motor. <IMAGE>

Title: Process and apparatus for the switching, where required, of heat generators and heating circuit pumps in heating systems
Inventor: VIESSMANN HANS
IPC: F24D19/10
Filed: 1982-08-10
Abstract: The invention relates to a process and also an apparatus for the switching, where required, of heat generators and heating circuit pumps in monovalent or bivalent heating systems as a function of the position of the mixing valve. According to the invention, when the mixing valve remains in a fully closed state during a predetermined period, the heat generator and also the heating circuit pump are switched off, if necessary after predetermined time delays, and after a first reopening, maintained for a predetermined period, of the mixing valve, the heat generator and also the heating circuit pump are switched on again, if necessary after predetermined time delays. Considerable savings of energy are possible with the inventive concept, because especially thermal losses in the primary circuit of the heat generator are avoided here if the heating circuit has no heat requirement with the mixing valves closed. The apparatus according to the invention can be easily integrated in, or connected to, existing heating plant control systems. <IMAGE>
