Abstract: 1428213 Gas sampling AERONUTRONIC FORD CORP 7 March 1973 [9 March 1972] 11187/73 Heading G1B In a gas sampling system, particularly for obtaining exhaust gas samples from an internal combustion or turbine engine, a chamber receives the emissions, diluent air being supplied thereto so as to form a mixture, the mixture flowing from the chamber to means for regulating the flow thereof comprising a Venturi device 34 operating at critical flow, i.e. under conditions wherein the gases reach sonic speed in the throat of the Venturi, a centrifugal air pump or blower 35 maintaining the sonic condition. Exhaust gases enter at inlet 25 and are mixed with air entering at inlet 28. A heat exchanger 32 is provided in the embodiment shown since the flow-rate at sonic conditions is temperature dependent. Probes 18a and 18b take samples of the air and the mixture of air and exhaust gases which are directed to bags (not shown) and subsequently analyzed. A single blower 35 may be coupled to a plurality of Venturi devices in parallel each having a separate exhaust input. In a further embodiment Fig. 6 (not shown), a constant percentage sample flow-rate is obtained. A probe at the inlet side of the Venturi device comprises a Venturi restriction provided with a small blower to maintain critical flow therethrough which flow is equal to the ratio of the areas of the two Venturis. Further, since the same temperature prevails in both Venturis, no temperature compensation is necessary.

Abstract: 992,854. Magnetic separation of gases containing oxygen. H. PAPST. March 23, 1962 [March 24, 1961], No. 11203/62. Heading B1L. The oxygen concentration in a gas mixture is increased by drawing a stream of gas through a channel less than 1 mm. wide which is traversed by a magnetic field of not less than 20,000 gas per sq.cm. from a zone containing said mixture, whereby oxygen preferentially enters said channel. In the embodiment shown in Fig. 1, two generally planar members 1, 2 of ferromagnetic material are separated by channel 3 and suction is applied to an outlet 5<SP>1</SP> communicating with duct 5 leading to channel 3. Members 6, 7 and 8 serve to complete the magnetic circuit. In another embodiment, Fig. 4 (not shown), the gas is drawn between two planar members so as to pass through the channel in one direction, duct 5 being omitted, by the inhalation of an operator. In another embodiment, Fig. 2, sector shaped prismatic members 11 together making up a hollow cylinder and separated by gaps 3<SP>1</SP> and permanently magnetized in the manner indicated, are supported in a framework and suction applied to the central zone 15. In the embodiment shown in Fig. 3a, a plurality of annular discs 23 are provided and the magnetic field is produced in gaps therebetween by means of coils 27, 28. Oxygen-enriched air is withdrawn through line 24<SP>1</SP>. In the embodiment shown in Fig. 5, a magnetic field is induced between consecutive turns 66 of a coil by means of a cylindrical permanent magnetic core 60. The gas of increased oxygen concentration is withdrawn from the zone between the coil and the magnetic core. Fig. 6 (not shown) indicates an arrangement whereby the concentration of oxygen in the gas may be successively increased by drawing the gas through a plurality of devices according to the invention.

Title: Improvements in or relating to the production of metals from their ores
IPC: C22B5/00
Filed: 1944-06-16
Abstract: 582,777. Reduction of ores. DUFFIELD, F. L. June 16, 1944, No. 11527. [Class 82 (i)] A method of reduction of metallic ores to their metals by charging such ores accompanied by the appropriate reducing agent into a chamber, capable of rotation and being rendered airtight, containing a segregated mass of refractory material which has previously been heated to a temperature at which such refractory mass contains sufficient superheat to provide for the reduction of the ore. In Fig. 1 a charging chamber A, a reducing chamber B, and a condenser D are joined together and are rotatable about a common horizontal axis. The charging chamber delivers a charge of ore and reducing agent, preferably in the form of a briquetted mixture, gradually to the reducing chamber which contains a segregated mass of refractory material, previously heated to provide the stored-up heat required for reduction. In the reducing chamber the briquetted charge is granulated by the crushing effect of the refractory mass during rotation, causing thin layers of ore and reducing agent to be presented to the hot surfaces of the refractory material. The contents of the charging chamber, reducing chamber and condenser may be subjected to a subnormal pressure. On completion of the reduction, the contents of the reduction chamber are discharged through an opening G on to a screen H where fines and reduction residues are separated from the refractory mass, the latter being hoisted by a skip K to the furnace C in which it is re-heated before being returned to the reduction chamber for the next cycle of operation. While special reference is made to the reduction and distillation of magnesium from an ore containing magnesium oxide or forming magnesium oxide at high temperature the apparatus, by elimination of the condenser, may be made suitable for the reduction of metals which do not sublime or vaporize at the operating temperature.

As shown, Fig. 1, a copyholder consists of a cover 11 resting on a holder 10 and releasably attached thereto. The holder can be turned about trunnions 12 from a horizontal to a vertical position. The cover 11 may be raised by shafts 14 on both sides thereof which slide vertically in a casing 15 and are operated by an electric motor at each side, extensions 21 of shafts 14 extend into lugs 20 on a lifting body which consists, as shown in plan, Fig. 2, of a hollow portion 16 closed by a plate 17. Studs 22 are threaded at right-angles into shaft extensions 21, and project through slots 23 in body 16. Plates 26, slidable in guides in the body 16, have slots 29 in which compression springs 28 are accommodated, bearing against the ends of the slots and against fixed projections to urge the sloping ends 27 of the bolts against rollers 24 on the ends of studs 22. Plate 17 has recesses 30, 31 facing upwardly and downwardly at each end to accommodate pins 32 extending from cover 11, so that the cover is free to turn with the holder 10 in the direction of the arrows.
