Abstract: 1,053,071. Waveguide filters. STANDARD TELEPHONES & CABLES Ltd. March 10, 1964, No. 10013/64. Addition to 987,593. Heading H1W. A waveguide hybrid junction comprises a rectangular waveguide 1, Fig. 1, having in opposite broad faces resonant slots 4, 5 coupling the waveguide to branch waveguides 2, 3. The longitudinal axes of the slots lie at right-angles to each other and their centres lie in the same transverse cross-section of the main waveguide. The slots are not necessarily parallel to the edges of the waveguides and the branch guides are not necessarily parallel to the main guide, nor are they necessarily of the same dimensions as the main guide. The Specification gives an analysis of the arrangement in which the impedances of the slots are expressed in terms of the characteristic impedances of the branch guides and the distances of the slots from the edges of the guides. Energy within a given frequency is divided between waveguides 2, 3 where it propagates in both directions. A bandseparating filter is described in which resonantcavity filters centred on adjacent bands f 1 , f 2  are arranged respectively on either side of the slot in each of the branch waveguides in such a manner that the band f 1  appears at the righthand ports of the branch guides and the band f 2  at the left-hand ports.

Abstract: 1,065,271. Mechanical calculating apparatus PITNEY-BOWES Inc. March 31, 1964 [March 29, 1963], No. 2064/64. Heading G4B. In a ten-key adding-listing or similar machine a one-tenth-value fraction is additionally marked on each key, and when a fraction key is depressed, normal movement of the pin carriage is prevented. The embodiment is a modification of the machine described in Specification 963,789, differing only in the structure and operation of the device for entering fractions. The keyboard unit (110, Fig. 1, not shown) has ten keys (112) which are identical to those of the earlier machine except that each key is also labelled with a fraction one-tenth of the normal value, and the keyboard includes a set-up or conditioning key (114). After the whole numbers have been entered in the normal manner, the conditioning key (114) is depressed and a downward extension (118) of its stem engages a stop member (120, Fig. 2, not shown) normally in the position shown, and depresses it so that a nose (130) moves into the path of one of three lugs (132, 134 and 136) carried on the indexing carriage support and thus prevents further tabulation of the carriage. The ten digit keys then act as fraction keys, all three sets of rack stops bars (41) including nine bars for this purpose. Reference has been directed by the Comptroller to Specification 963,789.

Abstract: 1,265,084. Automatic exchange systems. C.I.T.-COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS. 22 May, 1969 [12 June, 1968], No. 26292/69. Heading H4K. A radio telephone system is provided with call transfer facilities. The arrangement described enables a radio subscriber connected to a "private exchange" to transfer an incoming call to another subscriber of that exchange by pressing a button to earth the local loop and dialling the number of that other subscriber, the transfer being effected when the first called subscriber rings off. Relay circuit located at both ends of the radio link are described which by signalling in both directions over the link indicate to the exchange whether a radio subscriber has earthed his local loop or broken it and thus whether transfer or disconnect is to be effected. At a radio subscriber the two ends of the local loop are connected to the D.C. power supply over different windings of a first relay and corresponding windings of a second relay. With respect to the D.C. current in the loop the windings of the first relay are series aiding and the windings of the second relay are in series opposition. The potentials of the D.C. supply terminals are such that when the loop is broken at the subscriber's instrument the first relay operates alone, and when it is earthed the second relay operates alone. These relays control relays in the above-mentioned relay circuit. Each relay circuit is connected to its radio equipment by a four-wire connection, two wires to beused for speech and tone signalling and one wire for D.C. signalling in each direction. When a radio subscriber involved in a call earths his loop or breaks it, a potential is applied to the D.C. signalling wire at the subscriber end, and at the exchange end the relay circuit responds by starting a timer and returning a potential on the other D.C. signalling wire. The relay circuit at the subscriber end responds by removing the potential on the first D.C. signalling wire if the local loop is earthed. If no such response is detected by the time the timer times out the exchange assumes that disconnection is to be effected.

H 2 SO 4  is produced by oxidizing SO 2  to SO 3  in a multistage catalytic converter, dividing the gases leaving one stage into two streams one of which is cooled and the SO 3  therein condensed to form H 2 SO 4 , recombining the cooled and uncooled streams, and feeding them to the next stage, and condensing gases from the final stage to form H 2 SO 4 , water being added to the gases prior to each condensation stage if they do not already contain water. Preferably the gases are divided between the 1st and 2nd stages, and optionally also between the 2nd and 3rd stages, of a 3 stage converter, the proportion of gas which is cooled being 40-70% and 20-50% by vol. respectively. The cooled gas stream may be reheated in a heat exchanger before mixing with the uncooled stream, and in this case the proportion of gas cooled may be up to 90%.
