Abstract: 957,456. Intercommunication systems. STANDARD TELEPHONES & CABLES Ltd. Sept. 29, 1961 [Oct. 8, 1960], No. 35248/61. Addition to 955,569. Heading H4K. In the normal condition of a station all incoming lines 1a, 1b to 5a, 5b from the other stations are interconnected via individual linekey contacts LT1II-LT5II and LT1IVLT5IV and rectifiers Glr1-Glr5, and are applied via further line-key contacts LT1ILT5I and LT1III-LT5III and press-to-talk button contacts SpTII and SpTIII to the transducer SW of the station, so that upon actuation of one line key only the line to the selected station remains connected while the other lines are disconnected and the supply battery UB of the calling station is applied via a resistor Wi1 to the line to the selected station. If the selected station is idle the corresponding rectifier there is rendered conductive and a voltage drop appears across resistor Wi1 at the calling station, causing a tone generator RG to apply a calling signal to the transducers SW at both stations. The tone generator RB is disconnected by contact SpTI when the speech button is operated. In a modification, Fig. 2 (not shown), the tone generator RG is connected to resistor Wi1 through a capacitor so that it oscillates for only a short time after a station has been called. Also in this modification the stations are interconnected by individual single wires and a common wire, cross-talk being largely eliminated by the use of an additional transformer at each station to increase its resistance.

The inlet and outlet conduits are supported in flanged openings in the end caps and also in flanged openings 24 in perforated plates 22 spaced inwardly from the end caps to form sound attenuating chambers. The chambers 39 are rectangular in cross-section and are mounted in the shell by means of flanged end walls 44. At the upstream end of each chamber the flange of the end wall is joggled as at 50 and secured to the shell. A similar connection is provided by joggling the flange of the downstream end walls, as at 52. The joggled part of the flange is curved to correspond with the elliptical crosssection of the shell. A pipe 72 extends diametrically across the shell and has openings 75 through which compressed air is blown into the gas stream. The first chamber operates in a reducing atmosphere to convert oxides of nitrogen and the second chamber operates in an oxidizing atmosphere to convert carbon monoxide and unburned hydrocarbons. In a modification Fig. 6 (not shown) the first chamber slopes upwardly and the second chamber slopes downwardly in the direction of flow of the gas through the shell, so that the two chambers form an inverted V in the shell. An air injection pipe is provided at the junction between the chambers. Catalyst pellets are filled into the chambers through apertures which are subsequently closed by threaded plugs.
