Abstract: 1356468 Sulphur dioxide Claus gas mixture JOHN ZINC CO 28 May 1971 [15 June 1970] 17749/71 Heading C1A [Also in Division B1] A liquid spray of sulphur at a temperature of 295 to 305‹ F. is burnt with substantially its stoichiometric equivalent of oxygen at a temperature below 3000‹ F., and the resulting sulphur dioxide containing gaseous product is mixed with an acid gas containing H 2 S in order to provide a mixture containing about 1 mol. of SO 2  per 2 mols. of H 2 S. The combustion products may be maintained at a temperature below 3000‹ F. by mixing with a small amount of the acid gas. As shown (Fig. 1) a chamber 10 encloses a tubular member 17 which extends outside the housing 11 of the chamber 10, and member 17 encloses a chamber 14. Member 17 is joined to a similar member 18 of greater cross-section which itself is joined to an even wider member 16. Conduit 20 serves as an exit for gases leaving the member 16 and may lead to a conventional Claus plant. The sulphur spray is fed into chamber 14 by a pipe 21 equipped with a nozzle 22. The pipe 21 is surrounded by a jacket 23 and a smaller concentric pipe 25 forming an annular space between 23-25. In this space is disposed a pipe 26 for supply of steam at 300‹ F. to maintain the sulphur in a molten state. A gaseous fuel mixture is supplied to conduits 31 each of which is formed with a burner tip 33. Acid gas is fed through pipe 36 into the annular space 35 surrounding the sulphur burner assembly, and also by duct 45 into the member 16. The necessary oxygen is supplied to chamber 14 through ducts 42. The temperature of the mixture of H 2 S and SO 2  leaving by duct 20 is adjusted to about 465‹ F before passing to the Claus reactor.

Abstract: 278,114. Chalmers, F. Z. July 15, 1926. Controlling consuming devices. - The following four lighting conditions for two lamps 42, 43, e.g. the head lamps of a motor vehicle, are obtained by the manipulation of a single handle 39 viz.: both lamps bright, both dim, lamp 42 bright, lamp 43 dim, and lamp 42 dim, light 43 bright. These conditions are respectively obtained when the contact arm 39 bridges contacts 35, 36, or when it rests on contacts 37, 36, 38. The arm 39 may also slide over the dimming resistance so as to provide intermediate lighting conditions. Fig. 3 shows a modification in which substantally the same circuit arrangement is used, but in which means are provided, viz., the sliders 22, 23, for short-circuiting predetermined portions at the ends of the resistance. A rotary switch arm (not shown) is connected to the source of current and has four positions 90‹ apart. In position 15 it engages contacts 10, 11 and conveys current directly to leads 50, 51. In position 17 it engages contact 12 and conveys current to the leads 50, 51 through portions of the dimming resistance and in positions 16 or 18 it engages contact 11 or 10 and conveys current directly to one of the leads 50, 51 and through the resistance to the other lead. The leads 50, 51 ane connected to contacts 26, 27 of an auxiliary switch adapted to be connected to contacts 28, 29, leading to the lamps, by movable bridging members.

Title: Flowmeter
IPC: G01F1/80
Filed: 1960-05-23
Abstract: 877,605. Fluid-flow meters. BENDIX CORPORATION. May 23, 1960 [May 28, 1959], No. 18144/60. Class 69 (1). A fluid-flow meter comprises a powerrotated driver element 44, 46 connected by elastic couplings to a first impeller element 22 which accelerates fluid tangentially and to a second impeller element 32 which is accelerated when traversed by the rotating fluid, each of the impellers being angularly displaceable with respect to the driver element and means being provided to measure displacement between any two of the said three elements to indicate rate of mass flow. An electric motor 90 rotates a ring magnet 96 which couples through the non-magnetic casing 10 to rotate another ring magnet 97 fixed on the driver. Between the ports 46 and 44 of the driver is a drive-disc 42 which is coupled to the impellers through coil springs 82 and 86. The driver, the two impellers and the drive-disc are mounted coaxially to rotate independently of each other. Radial vanes (not shown) in conduit 18 align the flow of fluid entering the vanes 30 of impeller 22. The fluid, now rotating, passes thence through holes 80 in the disc 42 and passes through the vanes 38 of impeller 32 which it rotates in the same direction as the driver element. It then passes out through flow-rectifying vanes at 56 into conduit 20. In consequence of the passage of the fluid the impeller 22 tends to lag behind the driver element and the impeller 32 to lead on it, the relative motives taking place against the force of the springs 82 and 86. The lag or lead is measured against a time bore by magnetic pick-ups 98, 100 and 102 in cooperation with magnets 104, 106 and 108 on the driver and on the two impellers respectively. Stop-pins-112 and 116 co-operate with a stop 110 on the drive disc to cause one or other of the impellers to be coupled at will for direct rotation by the drive disc, thereby rendering either or both of the torsion springs inoperative, thus altering the sensitivity rate. The flow meter can be used to measure flow in either direction. Specification 857,052 is referred to.
