Title: Process for recovering excess ammonia in urea synthesis
IPC: C07C273/04
Filed: 1969-08-09
Abstract: The invention comprises a process for recovering excess ammonia in a urea-synthesis wherein carbon dioxide is reacted with a stoichiometric excess of ammonia in a synthesis zone at a urea-forming temperature and pressure, the excess ammonia contained in the resulting ureasynthesis effluent is separated as ammonia gas at a pressure lower than the said urea-forming pressure, the separated ammonia gas is cooled to form liquid ammonia and the liquid ammonia is recirculated to the synthesis zone for re-use therein, which includes separating the said excess ammonia from the said urea-synthesis effluent at a pressure substantially equal to the vapour pressure of ammonia at a condensation temperature at which the quantity of heat generated in the condensation of the ammonia gas is substantially equal to the quantity of heat required to elevate the temperature of the liquid ammonia raw material and mixing the thus separated ammonia gas with the liquid ammonia raw material, thereby condensing the said ammonia gas to form liquid ammonia at a high temperature. The separation of the said excess ammonia may be conducted at a gauge pressure of 40-120 kg./cm.2, for example, by adiabatically expanding said urea synthesis effluent, or by subjecting the ureasynthesis effluent to distillation at a temperature of 140-180 C.

Title: Dual mode automatic frequency controlled oscillator system
IPC: H03L7/107
Filed: 1971-12-03
Abstract: A dual mode automatic phase controlled oscillator system employs multiple keyed phase comparators to produce control signals which are applied to lock the oscillator frequency and phase to a reference signal. One of the keyed comparators is continuously employed to produce an in-sync control signal. A coincidence gate is utilized to detect the existence of out-of-sync conditions, and associated circuitry produces a mode control signal which is applied to activate the second keyed phase comparator upon such occurrence. The second keyed comparator is thereby selectively operative during out-of-sync conditions to develop an additional control signal to enhance the pull-in characteristics of the system.

Title: Method of and apparatus for controlling combustion
IPC: F23M20/00
Filed: 1976-12-15
Abstract: A liquid or gaseous (fluid) combustible is mixed with a combustion-sustaining gas and fed under pressure into a chamber where the mixture is burned. The mass flow of the combustible (fuel) is normally maintained constant for a combustion chamber of given thermal power output. The pressure in the chamber is continuously detected and the ratio of the mass flow of recirculated exhaust gas to the mass flow of the oxygen-containing gas (air or oxygen), which together constitute the combustion-sustaining gas, is increased when this pressure increases above a predetermined limit and the ratio is decreased when the pressure decreases below a predetermined limit. The ratio is varied by increasing or decreasing the proportion of exhaust gases and thereby decreasing or increasing, respectively, the partial pressure of oxygen in this combustion-sustaining gas.
