Abstract: 1,215,766. Treatment of hot 50 2 -containing gases. METALLGESELLSCHAFT A.G. 6 Nov. 1968 [7 Nov., 1967], No. 52692/68. Heading ClA Hot gases containing sulphur dioxide are cooled and saturated with water by passing the gases horizontally through a scrubbing apparatus divided into several zones in each of which sulphuric acid is passed downwardly with recycling of the acid in each zone, the dilute sulphuric acid being introduced into the zone adjacent to the gas outlet end of the apparatus, and wherein concentrated sulphuric acid is recovered from the zone adjacent to the gas inlet end of the apparatus, the method being performed without external cooling of the acid during recycling. The cooled gases may be subsequently contacted with active carbon to result in the formation of the sulphuric acid. In the Figure, hot SO 2 -containing gas enters at 1, passes over the bed of packing bodies 3, and cooled moist SO 2  leaves at 11. Dilute H 2 So 4  enters the reservoir 6 at 9, from which it is pumped to the top of the apparatus to a nozzle 4. Each zone has its own reservoir, pump 7 and nozzle, the excess H 2 So 4  from each reservoir being passed, via overflows 8, to the reservoir of the next zone. Concentrated H 2 So, is taken off at 10.

Title: Circuit arrangement for a telecommunication, particularly telephone exchange system

Filed: 1966-11-25
Abstract: 1,147,809. Automatic exchange systems. INTERNATIONAL STANDARD ELECTRIC CORP. 25 Nov., 1966 [1 Dec., 1965], No. 52921/66. Heading H4K. In a PBX, certain functional units, e.g. local, outgoing &c. junctors of the type disclosed in Specifications 963,329 and 1,049,623, are cyclically scanned and data regarding the state of their components and the conditions of the lines connected to them is passed to a central control where it is processed whereby data for altering the state of the components may be reverted to them. The transmission and reception of data takes place during successive halves of a time slot allocated to each unit. The central control's processing equipment consists of core or diode translators of which there is one for each different type of functional unit in the PBX. The scanner may be set on any particular unit. By scanning the actual components and lines of a junctor, a separate memory is not required. The junctor FE includes elements G which serve to identify its type, i.e. local or outgoing, remanent reed relays SE which are in fact the junctor's normal supervisory relays and gates TS which are connected to the junctor's input and output terminals. When the scanner ZE reaches FE during the course of the scanning cycle, the 'junctor type' is read-out from elements G so that the relevant translation field ZnO is seized in the central control ZL; the state of relays SE and the condition of gates TS are read-out and temporarily stored in a memory ES; and thereafter the results of the translation are fed back to the relays SE via logic circuit SpE. The relays SE are set in their " 1 " and " 0 " states by suitable signals on the x and y leads (Fig. 2, not shown).

Title: Voltage induced optical waveguide means
IPC: G02F1/035
Filed: 1973-11-29
Abstract: 1455286 Controlling light RCA CORPORATION 29 Nov 1973 55377/73 Heading G2F The disclosure relates to modified forms of a prior at electro-optic waveguide device, Fig. 2, wherein an electro-optic crystal 10 has a plurality of electrodes on a single surface, that plurality constituting all the electrodes of the device, and wherein at least one pair of electrodes or portions thereof are generally elongate and arranged in side by side relation so that a waveguiding region is defined in the crystal when a suitable potential difference PD is applied between them. In Fig. 2, electrodes 12 and 14 are parallel. Depending on the sign of the electro-optic coefficient the refractive index is increased to form the waveguiding region when the PD in a predetermined direction is either positive or negative. The PD actually applied may be A.C. or D.C. and of constant or variable amplitude. Light focused by a lens 25 is transmitted by lens 28 only when guiding occurs, e.g. when PD > 0 for LiNbO 3  crystal 10. The effective cross-section of the guide is a function of the PD amplitude whereby only part of the light from lens 25 may be intercepted and transmitted to lens 28 for continuously variable modulation. Due to birefringence, one polarization only may be selectively guided at any one time, or the guide may respond differently to different polarization. A solid state laser and/or photo-transistor may be directly incorporated into the guide structure rather than using external components and the lens 25, 28. Alternatively couples other than lens 25, 28 may be provided. In Fig. 3, to which the claims of the present Specification relate, light propagating in a guide 30-32 may be selectively switched to either and/or both guides 33-35, 36-38, the applied PD being of the polarity shown. A switching section comprises a centre triangular electrode 41 at a reference potential and electrodes 39, 40. Only when the latter have respectively a negative potential and a positive potential do the regions 42 and 43 act as guides. The device may be used in a reverse manner as a beam combiner. In Fig. 4, to which the claims of Specification 1455287 relate a wide light fibre 54 and a narrow fibre 53 are impedance matched via tapering electrodes 50, 51. In Fig. 5, to which the claims of Specification 1455288 relate, parallel electrodes 55, 56 have regularly spaced aligned lateral projections 58, 59. Light for which the spacing of the projections is an integral number of half wavelengths is selectively reflected by the refractive index grating produced when a PD is applied between the electrodes i.e. a reject filter. In each device the electrodes are preferably varnished to prevent arcing.
