Abstract: Solutions of aminomethylenephosphonic acids derived from diethylenetriamine and containing diethylene- triaminepenta(methylenephosphonic acid) as a principal component are commercial products useful as metal sequestrants. Known solutions, which usually contain not more than 9% by weight of hydrochloric acid, show a tendency to deposit solid aminomethylenephosphonic acid on storage. This tendency is overcome by increasing the mineral acid content of the solution to 10% or more of hydrochloric acid by weight of the solution or an equivalent amount of at least one other non-oxidising mineral acid.

Abstract: A digital duplex communication system for data signals having a power-versus-frequency spectrum comprising two side bands located one each side of a symbol frequency, the system comprising a transmitter/receiver which includes an echo canceller (4). The received signal is sampled at a multiple of the bit rate and comprises in each symbol period a first time during which data is valid (true eye 30) and a second time during which data is invalid (false eye 31). The receiver (2) includes circuitry to decode the data from the sampled signal during the true eye. 
     The echo canceller (4) is designed to be operative only during the sampling instant in the true eye (30) and at one of the zero crossing instants in each bit period. Thus the echo canceller is operative at the instants t, and t 2  but not at the instants t 3  and t 4  when no information is being extracted from the received signal. This enables the storage capacity of a look-up table type echo canceller to be reduced and the processing speed of a transversal filter type echo cancellerto be reduced.

Abstract: A method and apparatus for the crystallization of solids from liquids includes a vessel (8) having an elongate vertical spray chamber (10) which overlies and is in flow communication with a collection basin (22) for collecting slurry from the spray chamber. The collection basin has a cross-section larger than the cross-section of the spray chamber and preferably includes a side wall (24) which extends upwardly beyond the lower end (18) of the spray chamber (10) to define an opening between the wall of the basin and the spray chamber which communicates with the atmosphere. A blower (14) is located in the top of the spray chamber to draw air at substantially ambient atmospheric conditions through' the opening between upper end of the basin and lower end of the spray chamber and upwardly through the chamber (10). The slurry solution which is to be concentrated and crystallized is sprayed into the chamber and directly contacts the air flowing through the chamber thereby resulting in evaporation and concentration of the sprayed slurry and and crystallization of solids therefrom. The slurry collected in the collection basin is recirculated and returned as a spray at the upper end of the chamber. If desired, the recirculated slurry may be heated prior to being returned as a spray at the upper end of the chamber and the heating may be achieved in a heat exchanger (36) so as to utilize waste heat in its operation; this may also be employed to condense the otherwise wasted vapour from a series of vacuum evaporators and further concentrate the product.

Abstract: Products to be frozen are conveyed through an insulated horizontal tunnel having a plurality of individual cooling zones, each equipped with a radial fan rotating in a horizontal plane. Cryogenic liquid refrigerant is sprayed into one or more of the cooling zones in the central region of the tunnel, upwardly into the rotating fans and the thus vaporized refrigerant caused to flow in a downward direction in a recirculating pattern into contact with the conveyed products by vertical partitions between contiguous zones. The vaporized refrigerant flows from the supercold zone of liquid introduction beneath the edges of the partitions in two directions, outwardly towards the opposite ends of the tunnel in substantially equal amounts. The treated products thus undergo a continuously declining temperature gradient from inlet to outlet of the tunnel as a result of direct heat exchange with refrigerant vapor in counterflow thereto from the supercold zone to the products inlet and concurrent flow of the vapor from said supercold zone to the products outlet.
