Abstract: Certain impure steams, especially those from geothermal sources, are polluted with hydrogen sulfide, ammonia, carbon dioxide, other gases, and finely divided particulate solid matter in a form resembling dust or smoke. These contaminants reduce the efficiency of the steam as a heat transfer fluid, are detrimental to equipment utilizing steam as an energy source, and result in environmental pollution or expensive requirements for limiting the same. By the invention herein so polluted steam is selectively processed in the gaseous state upstream of said equipment to remove hydrogen sulfide therefrom, with or without removing other pollutants, to reduce environmental pollution from effluents thereof, to recover valuable materials therefrom, and to improve the utility of the steam as an energy source.

Abstract: A liquid feed and effluent system to recover dissolved process gas (e.g. H.sub.2 S) from an effluent process liquid (e.g. water), which liquid may also contain dissolved solid components (e.g. soluble salts); the system heats the feed liquid with heat recovered from the effluent liquid, saturates the so heated feed liquid with process gas, which gas may also contain inert gas components, and separately discharges from the system such inert gas components and effluent liquid from which process gas and heat have been recovered. In the combination the dissolved process gas is preferably recovered from the effluent liquid by flashing at progressively reduced pressures and final vapor stripping thereof at the most reduced pressure.

Abstract: Data processing equipment suitable for recording details of manually connected telephone calls has a plurality of operator stations with keyboards and VDU's connected in groups to operator's control units which respond to keyed instructions to obtain data from peripheral units storing such data and for recording on magnetic tape cartridge the details of the calls. Each operator's control unit is connected to eight operator stations but is capable of handling inputs from twelve such stations. In the event of breakdown of an operator's control units the eight stations allocated to it are divided into two groups of four which are transferred to the two control units adjacent to that which has broken down. Among the criteria used to determine whether a control unit has broken down are the filling of buffer stores and the failure to perform a particular operation within a predetermined interval of time following the previous performance of that operation.

Abstract: A method of error detection in a digital system in which at least one digit in every n (where n is an integer greater than two) is omitted from use as the "particular digit" in the comparison of succeeding particular digits in a received pattern with the combination in accordance with a predetermined function of at least two digits preceding the particular digit in question by a particular spacing. The pattern is a pseudo-random binary sequence of maximal length and every third digit is taken as the particular digit. Every digit forms part of a comparison whether as "particular digit" or as one of said "at least two digits preceding". Shift registers, means to divide digits between the shift registers, and modulo -2 adders are used to carry out the method.
