Title: Composition of road mixtures and method for their production
Inventor: RAGOŠKO
IPC: E01C7/00
Filed: 2014-11-19
Abstract: The invention relates to the field of road building industry, namely the instalation of motor road constituents. Paraffin production technology uses bleaching earth as an adsorbent. After the process the paraffined bleaching earth is removed from reactor. Said earth consists of adsorbent fine particles fraction and paraffin up to 5 %. The aim of invention is to improve the operating properties of the road coating and basic layer wich are building from mixtures without binders as well as to eliminate dustiness of such road coating or basic layer. The result is to be achieved by using for the road coating or for basic layer the mixture made from aggregate and hydrophobic additive - paraffined bleaching earth. The paraffined bleaching earth distributes in spaces among fine particles and dust and binds them. Thus, the operating properties of road coating and basic layer are improved and dustiness is eliminated.

Patent MX-9100478-A (MX)
Inventor: GENTER ROLAND
IPC: H04B3/23
Filed: 1991-08-01
Abstract: Residual echo from an echo canceler circuit is reduced by a variable attenuator that operates in response to a processing circuit which determines and adjusts an attenuation factor. The attenuation factor is determined by comparing relative levels of the send input signal, the receive input signal, and the error signal remaining after removal of an expected echo signal from the send input signal. The variable attenuator provides linear power attenuation of the error signal in order to reduce transmission of the residual echo signal and to eliminate the perception of coupling and decoupling of the telephone connection which occurs in known echo cancelers employing center clipping. A noise injection circuit provides a noise signal that is injected into the transmitted signal in inverse proportion to the attenuation of the error signal in order to provide a constant noise level in the transmitted signal as the error signal is variably attentuated.
