Abstract: The invention relates to the forming of a control pulse, for the transmitter in a GSM radio telephone system. A cos<2> pulse is formed by means of an analog circuit from a rectangular pulse which is first shaped into a triangular pulse which may be somewhat clipped at its peak. The triangular pulse is further shaped into a cos<2> pulse. The circuit also includes means (Cr...CN; R14...RN; Q7...QN) by using which the abruptness of the triangular pulse and thereby the abruptness of the cos<2> pulse can be selected.

Title: Hydrogen cyanide process and apparatus therefor
Inventor: COWELL CHRISTOPHER
IPC: B01J8/02
Filed: 1996-08-29
Granted: 2002-09-19
Abstract: A catalytic process and apparatus therefor for the manufacture of hydrogen cyanide. In the process an oxygen rich oxidant stream and at least one oxidant-free feed stream containing methane and ammonia are separately preheated and rapidly mixed to form a detonable mixed stream at a temperature which is at least 50° C. below the autoignition temperature of the mixed stream. The mixed stream is then conveyed to a catalyst capable of catalyzing the formation of hydrogen cyanide at such a velocity that detonation is avoided. The process is more energy efficient and gives rise to an effluent stream containing more hydrogen than the conventional Andrussow process.

Abstract: MULTI-FUEL ENGINE CONTROL WITH FUEL    COMPOSITION RESPONSIVE FUEL VISCOSITY CORRECTION            Abstract of the Disclosure A vehicle engine fuel control adapted for multi-fuel operation uses a fuel injection system in which fuel in a liquid mixture of first and second combustible fuels is injected in pulses of controlled duration at a predetermined pressure to achieve a predetermined air/fuel ratio.  The first and second combustible fuels have different viscosities, so that the viscosity of the mixture changes with its composition as well as fuel temperature.  The duration of the portion of the pulse duration in which fuel flows is varied in response to fuel composition and fuel temperature so as to compensate for the variation in viscosity of the fuel mixture and thus deliver the required amount of fuel with each pulse.
