Abstract: Transparent glass windows comprising thereon titanium silicide (TiSi2) as the principal solar screening layer for reducing transmission of near infrared and visible radiation. In some embodiments, a protective layer of silicon or metal oxide, about 300 angstroms thick, is placed thereover.  The protective layer serves to protect the silicide from oxida-tion during high-temperature processing procedures and increases the abrasion-resistance of the window product.  The particular importance of titanium silicide film is that it allows production of a window that is neutral in color when viewed in transmission as well as in reflection.  Thus, one is able to provide a durable, pyrolytic, high-performance, color-neutral, solar-shielding window product.

Abstract: ABSTRACT OF THE DISCLOSURE   A sum/differential signal processing circuit for use in a  sound  reproduction  system,  such  as  a  Dolby  surround processing   system,   includes   a   pair   of   operational amplifiers, a resistor connected between the inverting input terminals  of  the  operational  amplifiers,  two  resistors connected between the output  terminals of the operational amplifiers, a signal output terminal connected to a junction between the two resistors for producing the sum of output signals  from  the  output terminals  of  the  operational amplifiers.   A make switch is connected across one of  the two resistors,  which is selectively rendered ON and OFF.          When the make switch is ON, the sum of output signals of the operational  amplifiers  is  derived  from  the  signal  output terminal while when the make switch is OFF, the difference between  the output  signals  thereof  is  derived  therefrom.          Even when a monaural signal is applied to each of the two signal input terminals, the signal is not cancelled by the circuit thus arranged.

Abstract: Modern synthetic fibers, e.g. made of aromatic polyamides of high tensile strength have not achieved their potential for use as heavy-duty cables because of their smooth surface which gives rise to considerable difficulties in the transfer of high tensile forces, since they slip out of the clamping sleeves, and other force-transfer means based upon static friction, before reaching their ultimate tensile strength. This problem was solved in the invention by applying to the force-transmitting region thereof an impregnating material which breaks down into powder in the area to which the stress is applied, when the compressive or flexural stress exceeds the ultimate stress limit of the impregnating material. Particularly suitable for this purpose are natural resins, more particularly colophonium.

Abstract: A cellular radio system and a method for transmitting pilot channels in a cellular radio network includes, in each cell, at least one base station communicating with mobile stations located within its area. The base stations transmit a data signal in the downlink direction by using transmission directions that change in time and which transmit information about the system to the mobile stations on control channels. In order to enable the most efficient use of the pilot channels, the base stations transmit at least one first pilot channel with a predetermined radiation pattern and second pilot channels on transmission directions that change in time. The predetermined radiation pattern determines the cell coverage area.
