Patent GB-175612-A (GB)
Abstract: 175,612. Siemens & Halske Akt.-Ges. Feb. 19, 1921, [Convention date]. Automatic exchange systems.-In district office and like systems in which connections between subscribers in the same sub-office are normally completed over sub-office apparatus without tieing up the main office trunks, if all the local group selectors are engaged, the connection is set up over trunks to and from the main office. The invention is described as applied to a system similar to that shown in Fig. 2 of Specification 170.308. in which a calling line is extended over a first preliminary selector IVW of the usual type. and a second preliminary selector IIVW having two sets of contacts, one allotted to main office trunks, and the other to trunks leading to local selectors IIIGW. The preliminary selector IIVW first finds an idle main office trunk VL in the first set of contacts, but the first two digits in addition to operating main exchange switches, operate a local single-co-ordinate identifying switch MLW, which, if the call is a local one, completes a circuit for a relay N, which causes the response of a switching-relay U1 in the preliminary selector IIVW. The relay U1 locks up and transfers the test circuit of the relay T1 to an additional test wiper, under the control of which the rotary magnet steps round the switch to find a trunk in the second set of contacts, leading to an idle local group selector IIIGW, and the main office switches are released. According to the present invention, contacts 212 of the test relays Cl of all the local group selectors IIIGW are arranged in parallel in the circuit of a common relay G, over a front contact 213 of which the identifying relay N is energized. If a local call is made and all the local selectors IIIGW are engaged, the relay G is unable to energize over any contact 212 and the relay N will fail to respond. The connection will then be extended over a main office trunk VL and main office switches. According to a modification, the contacts 212 may be arranged in series in the circuit of the relay G, which is de-energized to break the circuit of the relay N when all the local selectors are engaged.

Abstract: 1300495 FET logic circuits TOKYO SHIBAURA ELECTRIC CO Ltd 28 May 1971 [30 May 1970 28 May 1971] 18062/71 Heading H3T A logic circuit consists of a plurality of pairs of complementary series-connected IGFET's each pair receiving a respective input at its commoned gates and providing an output at its common drains (or sources Figs. 5, 6, not shown) one pair 21N 21P being connected between two potentials and the other pairs being connected between one potential (earth) and the output of the preceding pair. In the Fig. 3 circuit the output of each IGFET pair is a NAND function of the inputs received by that IGFET pair and all the pairs above it. Similar embodiments using different combinations of IGFET types and supply polarities, and using either of the commoned source and commoned drain connections in each series pair, perform NOR functions (Fig. 4, not shown) OR functions (Fig. 5, not shown) and AND functions (Fig. 6, not shown). Complementary logic functions are described for input signals having reversed logic polarity. In Fig. 3, for example, output 013 will only be low if all inputs are high to provide a path through the three N-type IGFET's 21N, 22N, 23N, to -V; otherwise 013 will be earthed through whichever P-type IGFET 21P, 22P, 23P receives a low input. Circuits having more than three pairs of IGFET'S are described (Figs. 7, 8, not shown). In other embodiments (Figs. 9, 10, 11, 12) extra IGFET's are connected across the pairs of adjacent output terminals and supplied with the appropriate ones of the input signals to remove unwanted threshold drops which appear across certain of the logic IGFET's in the pairs, under certain logic conditions.

Title: Process and apparatus for heating metal
Inventor: CHURCHER THOMAS CHRISTOPHER
IPC: C21C5/34
Filed: 1963-05-08
Abstract: Metal in a converter or like vessel is heated by a medium introduced through a liquid-cooled probe passing through the bottom or side of the vessel.  The medium may be a flame resulting from the combustion of a gaseous, liquid, or powdered fuel with an oxidising gas, but is preferably a plasma stream produced by passing a stream of gas such as argon or nitrogen through an electric arc produced within the probe or between the probe and the charge.  When the charge has reached a suitable temperature, the plasma stream may be replaced by a stream of oxygen.  In a modification the plasma stream is formed from a stream of neutral or reducing gas, e.g. one containing hydrogen or coke-oven gas, containing desulphurising agents such as lime or calcium carbide.
