[Classes 83 (ii) and 83 (iv)] Angular bending; coiling; jointing.-Corrugated tubing is formed by profiling a strip 2 by rolls 3, 4 and helically winding on a mandrel 5 to form a tube with lap edges. An absorbent thread is drawn through a bath 16 of synthetic plastic substance and coiled between the laps of the strip. Rolls 6, 7 distribute the plastic material over the area of the overlap. The joint may be softened by a roller 9 connected in series with the mandrel and a transformer. The tubing is then stored at a temperature for setting the plastic material. The strip may comprise aluminium alloys known under Registered Trade Mark " Duralumin " or " Peraluman " or under Trade names of " Anticorodal " or " Avional."

Title: Improvements in and relating to radio receiving apparatus
IPC: H03G3/22
Filed: 1931-08-27
Abstract: 366,875. Valve amplifying and detecting circuits. BRITISH THOMSONHOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Carlson, W. L. ; King's Highway, Haddonfield, New Jersey, U.S.A.) Aug. 27, 1931, No. 24143. Convention date, Aug. 29, 1930. [Class 40 (v).] To effect automatic gain regulation in a radio receiver, the grid bias of an amplifier valve is brought to a positive value in response to excessive signal strength. The amplifier valve 20 includes in its grid circuit a portion of the supply potentiometer 9 between the tappings 12, 24, and an adjustable portion of the resistance 26 which is traversed by the plate current of the anode-bend detector valve 5. With no signal coming in, the detector passes no plate current, and the bias of the amplifier 20 is slightly negative due to the spacing of the tappings 12, 24. An incoming signal causes plate current to pass through the detector valve 5 and the resistance 26, and this tends to render the bias on the amplifier more positive. With increasing signal strength, the amplifier grid becomes sufficiently positive to cause a rapid diminution in amplification. As grid current damps the tuned input circuit 21 of the amplifier, the set becomes less selective and gives greater fidelity in reproduction. The detector grid is negatively biased partly by a tapping 11 on the resistance 9, and partly by the voltage drop in the resistance 26 due to the passage of plate current. The detector grid thus becomes more negative as the signal strength increases. The tuned amplifier 20 may be an intermediate-frequency stage, and the detector 5 the second detector stage, of a supersonic receiver.

Title: Process for the recovery of cyanopyridines
Inventor: HADLEY DAVID JAMES
IPC: C07D213/78
Filed: 1955-08-23
Abstract: 3- and 4-cyanopyridines are recovered from hot gaseous mixtures (e.g. from oxidation of picolines in presence of ammonia) by conducting the mixture at 100 DEG  C. or more into a scrubbing device where it is scrubbed with an aqueous solution of the reaction products under such conditions that the scrubbed gas leaves at a temperature not above 35 DEG  C. and the aqueous solution is not saturated with cyanopyridine; the solution is then conducted into a separate device where it is cooled to deposit the cyanopyridine; after separation the solution is recycled to the scrubbing device.  Under preferred condition the scrubbed gas leaves at about 25 DEG  C. and the solution at least 5 DEG  C. above saturation point.  The temperature in the separating device is about 5-15 DEG  C.  Examples are given of the process and suitable apparatus is illustrated.  The Provisional Specification refers to cyanopyridines in general.

Title: A method of reducing non-magnetic iron ores
IPC: C22B1/10
Filed: 1965-12-02
Abstract: 1,135,754. Reducing iron ores. PULLMAN Inc. 2 Dec., 1965 [7 Dec., 1964], No. 24254/68. Divided out of 1,135,753. Heading C1A. In a process for reducing an iron ore to magnetite, in which the ore in particulate form is heated by contact with hot combustion gases and then reduced at 800-1400‹ F., the gaseous effluents from the heating and reduction zones are combined and used to heat the ore in a preliminary zone. In Fig. 1, ore is fed at 10, heated in cyclones 18 and 12, and a portion is passed via line 106 to fluidized bed heating zone 110, maintained at 1400-1800‹ F. The bed is heated during start-up by burner 114, and at steady state by direct introduction of fuel via line 117 and air from line 118. The ore is removed down well 120, mixed with the remainder from line'102, and fed to reactor 140. Fluidized beds 142 and 144 in reactor 140 are separated by arcshaped baffle 138 having communicating orifice 146, and are fed by gases from partial oxidation furnaces 160 and 170 respectively, and by recycle gases from cyclone 18 via line 66. The gases may be of equal reducing strength, as described in Specification 1,135,753, or the gas from 160 may be made reducing and that from 170 oxidizing with respect to the particles entering the beds, as described in Specification 1,135,755. Effluent gases from 140 are separated from solids in internal cyclone 134, mixed with effluent from 110, and fed to cyclone 12, e.g. at 1000-2000‹ F. Solids from bed 144 are removed via line 152 and may be quenched with water in 150. In Fig. 2 (not shown), heating zone 110 is replaced by a transfer line heatexchanger, in which a suspension of the ore from cyclone 12 in hot gases from burner (220) are passed upwardly through conduit (210) and separated in cyclone (230). In Fig. 3 (not shown), reactor 140 is also replaced by transfer line reactor (240) and the conditions are preferably such that only a surface layer of Fe 3 O 4  is formed on the ore particles, the ore then being separated from the gangue magnetically. The ore may initially be ground to 10-325 Tyler mesh. The velocity of the gas/solid suspension in 240 may be 10-90 ft./sec. and the residence time 0À5-12 sees. The reduced ore from 240 is separated in cyclone (244) and cooled in cyclones (260 and 264) with recycle gases from 66, gas from 260 being fed to 240. Reactor 240 may be followed by a fluidized bed reactor to form further Fe 3 O 4 . The ore may be hematite, siderite, or limonite; any FeCO 3  is converted to Fe 2 O 3  in the heating zone.

The cope feeding means in a roller conveyer 5, 35 which is aligned with two counterweighted pivoting bars 62, 63 (carrying rollers 6 and mounted on the cope transfer platform 27-34) when the cope transfer platform 27-34 is in its raised position. A cope 2 is rolled on to rollers 6 and its lug 43 engages a limit switch 74, the lug 43 being centred by inclined magnetized bar (81, 82, not shown). Engagement of limit switch 74 initiates downward movement of the platform 27-34 by a control circuit (not shown). When cope 2 and drag (1) are in engagement cams 65, 66 attached to the pivoting bars 62, 63 disengage from holding rods (67, 68, not shown) and the pivoting bars 62, 63 tilt to release the cope 2. The tilting of bars 62, 63 operates a further limit switch (73, not shown) which initiates upward movement of the platform 27-34, the pivoting bars 62, 63 being returned to their original positions by the cams 65, 66 engaging holding bars 67, 68. As the platform 27-34 moves upwardly a bar 28 thereof engages a plate 91 (not shown) and retracts stops 85, 86 by a lever mechanism (not shown) so that the assembled casting mould may roll down the inclined conveyer 3. As seen in Fig. 4 the assembly apparatus C can be employed in a plant including a drag moulding machine A and a cope moulding machine B. A preliminary drag aligning device 4 is provided comprising a pair of drag-engaging fingers 94, 95 (Fig. 13) pivotable in a horizontal plane and linked by a lever arrangement 95, 96, 97 to pivot in opposite directions to the same extent.
