Filed: 1973-02-07
Abstract: 1416792 Gas sampling ITT INDUSTRIES INC 7 Feb 1973 [7 Feb 1972] 6048/73 Heading G1B A gas sampling and analyzing apparatus comprises a piston 94 reciprocable in a p.t.f.e sleeve 86 between a first position (as shown in Fig. 2) in which a bore 103 of the piston communicates with the gas atmosphere around the device via ports 105-108 in the sleeve 86 and outer tube 11, and a second position Fig. 5 (not shown) in which bore 103 communicates with conduits 96, 97 through which a carrier gas flows to remove the fluid sample in bore 103. Piston 94 is biased to the first position by spring 125 and is repeatedly moved to the second position by a solenoid 29 fed with a square wave Fig. 8 (not shown). A pin 112 engaging a slot 111 in the piston guides and limits the movement of the piston. Conduits 96, 97 are formed by grooves in the sleeve 86, Fig. 3 (not shown) and air is supplied to conduit 96 via needle valve 54 and line 21 Fig. 1. In the first position of piston 94, a second bore 104 in the piston connects the conduits 96, 97. Conduit 97 is connected to a mixer tank 62 via line 23, and the mixer tank is connected to coulometric titrator. A pipe 25 connected to a solenoid valve 46 passes along a groove 98 in the sleeve 86, and communicates with bore 103 when the piston is the first position. The solenoid of valve 46 is energized by a square wave such that it is energized in each period between successive energized periods of solenoid 29 Fig. 8 (not shown). Thus immediately after the return of piston 94 to the first position, solenoid valve 46 operates for a period to connect pipe 25 to a needle valve 55 via line 59 to produce a purge flow of air in bore 103. In the periods when solenoid valve 46 is not energized, pipe 25 is connected to a pressure indicator 61 which indicates the pressure in bore 103 whilst the piston is in its first position. A temperature sensor 102 is provided in a further groove 99 in the sleeve 86. The device may be used for sampling the gas in a flue 15 in order to measure the hydrogen sulphide and sulphur dioxide concentrations. The tube 11, tube 13, flanges 16, 17, 19, tube 18 and cover 20 may be of stainless steel. Cover 12 may be of p.t.f.e.

Title: Improved process for treating iron chloride lyes
IPC: C01C1/16
Filed: 1923-03-07
Abstract: In the evaporation of solutions containing ammonium chloride such as the residual lyes from the ammonia soda process in order to obtain ammonium chloride, corrosion of the iron vessel is prevented by the passage of a weak direct electric current.  The latter enters the liquor through an iron electrode and leaves by the iron walls of the vessel.  A current of 0.1 amp<\>gere per square decimetre of the wetted surface of the evaporating vessel which acts as the cathode is employed.  The sodium chloride which separates during the evaporation is continually removed by a salt separating device.  After crystallization of the ammonium chloride fresh quantities of ammonium chloride lyes are mixed with the mother liquor which is then returned to the evaporator.
