Abstract: 1,228,051. Typewriters. ING. C. OLIVETTI & C. S.p.A. 11 Sept., 1968 [30 Sept., 1967], No. 43284/68. Heading B6F. [Also in Division F2]  A parity-checking device for use with a teleprinter or other equipment having a plurality of code members 2, Fig. 1, positionable in accordance with the binary units of a given code combination comprises a pair of elements, e.g. 4 and 8, Fig. 2, each of which is movable between two positions in response to the setting of a corresponding member 2, and means 22 interconnecting the elements 4, 8 to shift a further element 12 between the two possible positions each time either but not both of the elements 4, 8 change position. The embodiment of Fig. 1 comprises eight elements 4-11 connected by rods 22 in the pairs 4, 8; 6, 10; 5, 9; 7, 11. Each element is pivotable about a pin 3 between two positions situated respectively to the left and right of the vertical. One element, e.g. 8, of each pair is pivotally connected to a rod 22 and the other, e.g. 4, has a pin 24 movable along a V slot 23 in the rod. Thus, a slot 21 in each rod 22 will adopt one of two vertically disposed positions corresponding to the states of parity and disparity of the two elements, Figs. 2-5 (not shown). Levers 12 and 14, pivoted about a fixed pin 17, and levers 13 and 15, pivoted about a fixed pin 18, each have a pin 19 engaged in the slot 21 of a rod 22 so that each lever adopts a vertical position corresponding to the state of parity or disparity of its pair of elements. Parity and disparity between the levers 12, 13, and 14, 15, respectively is detected by rods 32 pivotally connected to the levers 12 and 14, and having V slots 33 engaged by pins 34 on the levers 13 and 15. Arms 26, 27, pivoted on pins 28 are connected to the rods 32 by pins 29 in slots 31, and are connected to each other by a pivoted rod 42 having a slot 43 engaged by a pin 44 on arm 27. A lug 46 on a reciprocating lever 36 will thus adopt one of two vertically disposed positions, corresponding to parity and disparity, respectively, of the code members 2. An electrically driven eccentric 37 reciprocates the lever 36 such that a projection 47 of the lug 46 depresses a microswitch 48 when the lug is in its upper position, corresponding to disparity. Immediately after the members 2 have been positioned according to a code combination, an eccentric 53, Fig. 9, causes a blade 59 to engage aligned grooves in arms 62 and 63 to fix their positions and hence the height of projection 47. The eccentrics 37 and 53 are both mounted on a continuously rotating shaft 38. This device has a plurality of members 2, for example seven, and in this case the device of Fig. 1 may be used with one member 2 locked. The device may be incorporated in the keyboard of a teleprinter, as described in Specification 1,082,776.

[Also in Division Cl] A reactor in which pulp liquor is carbonised to an activatable carbon comprises a reactor chamber 1 into which a free oxygen containing gas and/or an atomising gas is passed together with spent pulp liquor under pressure through an atomising nozzle 4, there being in the chamber adjacent to the nozzle but axially spaced from it an open ended tube 5 coaxial with the spray emerging from 4 so that the spray passes through the tube 50 as to cause a recirculation of the gaseous combustion products back to the spray adjacent the nozzle so as to maintain the temperature of the reaction. As seen in Fig. 2 the nozzles 4 may be arranged horizontally and radially or as in Figs. 3 and 4 the nozzles may inject a stream vertically downwards into the reaction chamber. The pulp-liquor the oxidising and the atomising gas may be preheated, and before admitting the pulp liquor the chamber may be brought to temperature by passing fuel gas through nozzles 4 or through auxiliary burners (not shown) or alternatively as shown in Fig. 4 by means of auxiliary electric heating elements 39. The gaseous and solid products may be removed through a single orifice or through separate orifices 10 and 11. The gaseous effluent from 10 may be treated to remove finely divided solid, and its sensible heat utilised, by passing through a heat exchanger, to preheat the feeds to the reaction chamber. Water vapour is removed from the gases so cooled and the residual gas may be burned to provide further heat to the reaction chamber.

[Also in Division F1] A fan or the like, e.g. for cooling automobile engines, comprises a rotor which is mounted in a cylindrical duct 2, Fig. 2, and has radiallyextending blades 3 with spanwise-extending apertures 7 therein for discharging fluid substantially tangentially over the blade outer surfaces. The blades are hollow and of substantially circular cross-section as shown, and may be interdigitated with blades of aerofoil crosssection with or without discharge apertures. The aperture 7 is in the trailing region of each blade relative to the direction of rotation, so that during operation the air flow around the blades induces air from within the blades to flow through the apertures 7, the latter flow drawing air through the duct 2. The ratio of mean aperture width to blade chord may be 0À01. The aperture width may vary radially from a minimum at the hub 4. Each blade may have more than one aperture, and the apertures may be arranged to discharge in opposite directions at will for reversing the flow through the fan without reversing the direction of rotation. Each blade may be provided with diametricallyopposite slots at its tip for fluid flow therethrough to reduce losses at the tip. The flow circulating in or around the duct 2 may be controlled by discharge of fluid through at least one aperture formed in the duct wall. The air flow through the aperture 7 and thereby the flow through the fan, can be controlled by a valve 8. In an alternative embodiment, Fig. 4 (not shown), the air flow through the apertures is delivered thereto by a vane-type compressor (9) and is controlled by a valve (10) arranged upstream of the compressor.

Abstract: 1297997 Semi-conductor pulse circuits TEKTRONIX Inc 11 March 1970 [21 March 1969] 11574/70 Heading H3T A symmetrical (unity mark-space ratio) pulse output e 4  is derived from an input signal e 1  by generating a triangular wave e 3  which has an average value dividing it into equal time intervals and generating the edges of the pulse output as the triangular wave e 3  crosses this average value. An emitter coupled switch T 18, 20 receives e 1  and a reference earth voltage whereby the transistors alternately conduct to charge and discharge capacitors 30, 36. A triangular wave e 2  is thereby produced at 26 and its complement at 32. These waves are capacitor coupled (44, 38) to the bases of a second emitter-coupled switch T 40, 46, whose base resistors 42, 48 are earthed to hold at earth potential the average value of the triangular waveform e 3  at T 40 base and its complement at T 46 base. A transformer 52 is then pushpull driven to give the unity mark space pulses e 4 at 62.
