Title: Process for the absorption and subsequent recovery of sulphur dioxide from gases containing the same
IPC: C01B17/60
Filed: 1937-05-20
Abstract: <PICT:0489745/III/1> In the continuous recovery of sulphur dioxide from gases, the sulphur dioxide is absorbed in a solution of alkali metal or ammonium sulphites and sulphate containing such amounts of these salts to make it nearly saturated at the absorption temperature with respect to sulphate only, the absorbent solution is treated to expel pure sulphur dioxide, a part of the water is eliminated from the solution which is then cooled sufficiently to crystallize controlled amounts of sulphate, the crystallized sulphate is removed, and finally the absorbent solution is restored to its original condition by the addition of water and alkali or ammonia and recycled to the absorption stage of the process.  Sulphates formed by oxidation are thereby eliminated from the system.  When using ammonium salts, a sufficient concentration of an ammonium salt such as ammonium phosphate may be maintained in the solution to depress the solubility of the ammonium sulphate.  The removal of the necessary water may take place in the sulphur dioxide recovery step and/or in the sulphate crystallization step.  Roaster gases containing sulphur dioxide flow through absorption towers A and B in counter current to an ammonium monosulphite-ammonium bisulphite solution which enters the top of tower B at a temperature of below 50 DEG  C.  The solution also passes through a cooler E interposed between the two towers. The liquor withdrawn from the tower A is substantially ammonium bisulphite and is heated in a tower C to 110 DEG  C. to drive off the sulphur dioxide.  Considerable sulphate is formed by oxidation during the absorption and regeneration stages as a result of which the liquor leaving the tower C at 110 DEG  C. is saturated with sulphate.  The liquor passes to a vacuum crystallizer D, which has a temperature of about 70 DEG  C.  Here water is evaporated and ammonium sulphate separated by crystallization.  The solution is then replenished with water and ammonia and is returned to the top of the tower B.

Title: Time division multiplexed loop communication systems
IPC: H04L5/22
Filed: 1976-04-07
Abstract: 1498766 Selective signalling INTERNATIONAL BUSINESS MACHINES CORP 7 April 1976 [14 May 1975] 14068/76 Heading G4H [Also in Division H4] In a time-multiplexed loop communication system including a controller and a plurality of terminals connected to a signal transfer loop, the controller is adapted for defining a repeated sequence of time slots and for issuing terminal commands in such slots, each terminal having one or more slots assigned to it and being responsive to a command in such a slot including the address of a device attached to the terminal to connect the device to the loop and disconnect any currently connected device. Terminals may share the same slot(s). A command will be executed by the terminal (of those assigned the slot in which it occurs) having the device corresponding to the address in the command. All other terminals assigned the same slot go into "pass mode" in which they cannot send an "attention" command to the controller. The controller, after finishing communications with the device addressed, can send a "leave pass mode" command (in the slot) which cancels the "pass mode" and, e.g., permits issuing of "attention" commands to the controller. Such a command includes the terminal or device address which forces down-stream terminals assigned the same slot into the "pass mode". The controller echoes the "attention" command back to the terminal as a transmission check, and this forces the up-stream terminals assigned the same slot into the "pass mode". The controller may interrupt a communication by sending the "leave pass mode" command and resume it later by sending a command with the required device address. Slots can be assigned to a terminal using a "set modulus" command. Devices attached to a terminal have address compare circuits for recognizing their own addresses. When a device wishes attention it notifies logic in the terminal and this logic determines which device is involved by supplying their addresses in turn to the address compare circuits.

Title: Methods and apparatus for the determination of resistivity or thickness of semiconductive bodies
IPC: G01N22/00
Filed: 1961-04-19
Abstract: 987,613. Measuring physical dimensions; measuring resistivity of semi-conductive material. WESTERN ELECTRIC CO. Inc. April 19, 1961 [April 27, 1960; May 31, 1960], No. 14137/61. Headings G1N and G1U. In an arrangement for determining the resistivity or thickness of a semi-conductive material, a sample is placed, if necessary with a conductive backing, in an aperture in a conductive wall portion of a hollow, wave transmission path and the transmission characteristics of the path including the sample, when it is energized by ultra high frequency radio, are measured, the thickness or resistivity being determined by comparison with transmission characteristic measurements of semiconductors of known resistivity and/or thickness. The wave guide 13, Fig. 1 including the sample 18 under test, is energized through an attenuator 12 by a generator 11 producing energy in the range of 8000-65000 megacycles per second, and a directional coupler 15 comprising a four terminal hybrid junction directs the incident signal from the generator to detector circuit 16 and the reflected signal from the line terminating test sample to detector circuit 17, the two detector outputs being applied alternately to an oscilloscope 28 by a change over switch 27 oscillating at 30 C.P.S. To measure the return loss attenuators 20, 26 are zeroed and attenuators 22, 24 adjusted for equal signal amplitudes from the detector circuits. The sample is then replaced by a good conductor, and attenuator 26 is adjusted to again produce equal detector outputs, the loss being determined from the attenuator setting. Resistivity can be determined by reference to a graph. The penetration determined by the frequency chosen should not be greater than the thickness of the semi-conductor but if unavoidable a method employing backings of differing resistivity may be used. The sample support structure may be adapted for rapid change of slide-mounted backing materials, change of backing being achieved without removing the sample from the aperture. In a modified arrangement Fig. 2 a high Q resonant cavity 31 lightly couples a detector 33 to a generator 32, and a directional coupler 38 couples the input of cavity 31 to a second detector circuit 40, the outputs of the two detector circuits being connected to an oscilloscope as before. Isolaters are provided on each side of the cavity to prevent feedback. Cavity 51, Fig. 3, is bounded by brass plates 53, 54, half a wave length apart and apertures 55 couple the cavity to the remainder of the guide. Opening 72 in the smaller wall is provided for receipt of the test sample which may be supported from wings 56. A screw 59 is provided to adjust the transition impedance between wave-guide and cavity.
