Abstract: 1321096 Mixing apparatus RHEINSTAHL HUTTENWERKE AG 27 Aug 1970 [6 Sept 1969] 41298/70 Heading B1C [Also in Division C7] Apparatus for desulphurising pig iron in the tapping channel of a blast furnace comprises a container 2 with refractory inner surface, an axial inlet channel 3 and tangential outlet channel 4, and a rotatable refractory beam stirrer 8, 9 which in operation is rotated against the direct flow from the inlet to the outlet, see Fig. 3. Desulphurising agent is introduced at 12. As shown the roof of the inlet 3 is below the melt level and may be below that of the outlet weir 7 to prevent ingress of blast furnace slag and escape of desulphurising agent; the roof of the outlet 4 is above the level of the inlet and above that of the outlet weir 7 but below the top of a barrier 6 which arrests the spent desulphurising agent thus separating it from the melt. The floor of the apparatus slops slightly from inlet to outlet; the container and stirrer are detachable and can be lifted and exchanged by a crane. Fig. 1 shows an arrangement suitable for use with a blast furnace having a tapping hole at the level of the channel, but if the hole is at a higher level both the melt and the desulphurising agent may be fed in a joint stream (see Fig. 2, not shown) through an aperture in the container cover. Suitable dimensions are given for outputs of 1-7 turns/min. A desulphurising process is claimed in which the degree of base CaO/SiO 2  of the blast furnace slag is less than 1.2, and/or the coke used has a sulphur content greater than 1%, and the sulphur content of the pig iron is reduced in the apparatus described.

Abstract: 1,020,968. Transistor logic circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. Oct. 19, 1964, No. 42532/64. Heading H3T. A logic circuit comprises a bridge circuit comprising, between the input terminals 5, 6, two diode arms 12 and 13 in series and two emitter-base diode arms 14 and 15 in series, a resistor 11 being connected across the other diagonal 9, 10. In the circuit shown, when the signals at 5 and 6 are equal no current flows in the transistors 14 and 15 so that transistor 19 is conducting. When 5 is positive with respect to 6, current flows in the path 12, 11, 15 so that transistor 15 conducts and 19 is cut off. Similarly, transistor 19 conducts when 6 is positive with respect to 5. Accordingly, the circuit performs an " exclusive OR " function. Diode 23 prevents transistors 14 and 15 saturating and diode 24 prevents 19 saturating. In addition, the charge stored in diodes 12 and 13, when conducting, provide a discharge path for charge stored by the transistors 15 and 16, respectively when the signal terminates. Fig. 1 (not shown) is a simplified circuit having the diodes and emitter-base paths reversed.

[Also in Division G2] In an optical display system in which linearly polarized light is focused on to a screen by means of a light-deflecting device, the dispersion between colours is compensated for by a device having different focal lengths for at least two wavelengths. A collimated linearly polarized laser beam 16 is passed through a lens 12 and a digital light deflector 14 which is arranged so that the path length of a light ray of a given colour is the same no matter what path it takes. The light is then passed through an electrooptic switch 22 which rotates the plane of polarization of red and blue light so that they pass through a birefringent lens 24 as ordinary and extraordinary ray respectively to reach a common image plane 28 on screen 26. In another embodiment, Fig. 4 (not shown), a passive birefringent plate (42) may be included between the lens 24 and the switch 22 to relax the material and design requirements on the lens if necessary.

[Also in Divisions A6 and B7]  A wall floor or partition structure for a building, vehicle or toy comprises panels of modular width some at least of which are of two or more modules wide and provided with intermediate stringers at modular intervals and edge stringers both types having interlocking or keying formations and wherein the formations of two edge stringers of two panels in juxtaposition at panel parting lines are jointly equivalent to the formations of an intermediate stringer. In Fig. 1 panels 1-5 have intermediate stringers 7 and edge stringers 8 engaged with corresponding formations on structural members 16 and if desired with terminal members 6 which may form a jab for a door or window. In a hollow wall, Fig: 26 panels 91-94 in an outer panel row and 95-101 in an inner row have edge stringers 102, 103 and intermediate stringers 104 which are engaged together to form stress members. Numerous variations in the types of stringer formations are illustrated and in many cases keys are used between the stringers and their co-operating structures but in all cases the stringer and structural member formations are interlocked or keyed together by means of lengthwise slidable and otherwise relatively immovable engagement with each other or with keys. At corners in the structures the stringers 8b, 8c or 107, 108 are offset diagonally while at partition junctions stringers 109, 110 are off-set diagonally to engage with each other and with stringers 103, 102c in the outer row. In some cases the stringers are non-continuous and are engaged together by frontal movement after which keys are inserted by lengthwise movement in some cases the keys being a spring fit which forces the stringer parts into engagement.
