Patent GB-2191650-A (GB)
Title: Wave signal direction-finding
Inventor: CUSDIN ANTHONY RICHARD
IPC: G04F10/00
Filed: 1986-06-10
Abstract: A method and a system for determining the direction of incidence of wave signals such as radio or sonar signals by using Time of Arrival (ToA) and interferometric measurements on parallel, substantially coincident baselines. The measured phase difference on the widest-spaced ANT3, ANT5 of one or more pairs of wave-receiving elements ANT3, ANT4, ANT5 provides the desired accuracy, but even after reference to the measured phase difference on the closest-spaced pair of elements ANT4, ANT5 of the interferemeter is ambiguous. This ambiguity can be resolved by reference to the time difference  DELTA t measured between the ToAs of signals at two elements ANT1, ANT2, since both DF arrangements measure the angle alpha between the direction of incidence and the common baseline, provided that the range of possible values of the actual time difference due to the uncertainty in the measured time difference DELTA t corresponds to a range of  alpha  not greater than the unambiguous range of  alpha  from the phase measurements. Such an arrangement can require less equipment than a purely interferometric arrangement. By using two coplanar, mutually inclined baselines, directions of incidence in three dimensions may be determined (Figs. 2,3,4). <IMAGE>

Title: Dispenser for two-part adhesive
Inventor: GRANT QUENTIN SHOLTO
IPC: B05C17/005
Filed: 1987-03-02
Abstract: A nozzle for dispensing flowable components of a two-part chemically reactive system defines a separate respective dispensing passage (40,41) for each component of the system, each passage having an opening (42,43) adjacent a tip of the nozzle, the nozzle being configured such that at least one said opening is spaced axially from a point (39) at which components being dispensed through the passages come into contact with each other. This off-set arrangement of at least one opening from the point at which components come into contact with each other ensures that when the flow of the component ceases there is a separation between the components so that no further reaction takes place. This prevents the end of the nozzle from becoming clogged by an excess of the components which has set hard at the end of the nozzle. In the arrangement of Fig. 6 wherein the nozzle comprises inner and outer co-axial passages for the two components,the nozzle is connected to the valved outlet spigot (7) of a container (Fig. 1), having separate compartments for the components, by means of a coupling which includes a frusto-conical flange (32) having a projecting member (33) with a bore (34) for feeding one of the components to the inner tube (30). The flange (32) includes notches (35, Fig. 8) for feeding the other component into the annular outer passage. <IMAGE>

Abstract: In a process for the synthesis of urea the improvement is described in which the decomposition and separation of unconverted raw materials which are conventionally performed at a pressure equal to the pressure of the synthesis reaction by stripping and formation of ammonium carbamate, are partially replaced by decomposition and separation thereof and absorption thereof under a medium pressure which is lower than the pressure of synthesis reaction, the unconverted materials being separated as a first gaseous mixture under the synthesis pressure, a second gaseous mixture under a medium pressure which is lower than the pressure of synthesis reaction and a third gaseous mixture under a third pressure which is lower than the said medium pressure, and the separated unconverted materials recycled by absorption of the second gaseous mixture in a solution of the third gaseous mixture at the medium pressure and absorption in the resulting solutions at the synthesis pressure of a portion of the first gaseous mixture, the resulting aqueous solution and unabsorbed first gaseous mixture being recycled to the synthesis section, and in which the heat generated in the said absorption is utilized in the overall process to reduce the amount of high pressure steam required in the overall process and reduce the amount of low pressure steam generated, the ratio of total ammonia to total carbon dioxide in the synthesis section being maintained within the range of from 2.8 to 5.0.
