Patent DE-2512691-A1 (DE)
Inventor: SIEGMUND WERNER
IPC: E01C7/08
Filed: 1975-03-20
Abstract: The road covering contains a frost-resistant means (7), e.g. salt, by means of which the freezing point is reduced. The salt (7), the binder and the filling material (5) are not to be in the form of a mixture since, otherwise, the salt quantity is restricted due to the binding capacity of the binder. The binder and the filling material (5) alone are to form a mixture which contains cavities (6). The salt (7) is embedded in said cavities. As the mixture is gradually worn away by the traffic, the cavities (6) are exposed and the salt becomes effective. The best mixture, in terms of durability, can thus be selected without taking the salt content of the covering into consideration. The cavities (6) of a porous, granular filling material (5) may be used to receive the salt. First of all, the salt (7) is introduced into the cavities (6) of the grain (5), and then the grain is mixed with the binder to obtained the covering. <IMAGE>

Title: Earth fault location in electronic power supplies - uses diodes with bridging contacts to initiate current change when fault detection circuit is broken
Inventor: WEISS BALDUR
IPC: G01R27/18
Filed: 1975-12-06
Abstract: The supply from a common source to each load circuit has a series forward biased diode bridged by a switch. Earth fault detection and location equipment is connected to the supply busbars. If an earth fault occurs it is detected and an increased current forced to flow in the fault loop; an alarm is also initiated. When the bridging diode switch of the affected path is opened there occurs a small voltage drop due to its internal impedance. This is detected in the location unit, typically as a small change in current, and drives an indicating instrument. Switching the other circuits has an effect because their current is not provided in part by the fault detection circuit.
