Title: Improvements in or relating to the concentration of hydrazine solutions
IPC: C01B21/16
Filed: 1952-01-24
Abstract: Concentrated hydrazine solutions or substantially anhydrous hydrazine, e.g. 95 per cent. or over, are prepared by intermixing aqueous hydrazine solution or hydrazine hydrate with solid sodium hydroxide in the proportions of at least one mole of sodium hydroxide for each mole of water present at a temperature of 60-100 DEG  C., preferably 60-80 DEG  C., and separating the hydrazine rich phase from the hydrazine lean phase either by fractional distillation under reduced pressure or by allowing the mixture to become substantially quiescent and to stratify and mechanically separating the resulting two layers of liquid.  A dilute solution of hydrazine hydrate, e.g. 35 per cent, or above, is quickly mixed with a 1:1 to 2:1 mole ratio of commercial caustic soda and maintained as a completely liquid system at above 60 DEG  C.  The vessel containing the mixture is connected to a distillation system and the pressure reduced to say 90 mm. when the hydrazine vapours produced are condensed.  The temperature may be increased from 60 DEG C. during distillation. Alternatively, a higher pressure to prevent distillation may be maintained to permit the formation of two layers the upper of which contains at least 75 per cent. of at least 88 per cent. hydrazine and the lower of which contains sodium hydroxide monohydrate and some hydrazine.  The upper layer may be separated from the lower by siphoning or decantation and the upper layer may be separately distilled or the upper layer may be distilled without separation from the lower.

Class 112 Embroidery, chain stitching, multi-needle machines, connecting upper and lower shafts. A sewing machine comprises a pair of needles which are disposed respectively above and below a work plate and co-operate with respective loopers to produce parallel lines of loosely formed chain stitches in two superposed layers of fabric. When said layers are subsequently separated, the respective threads are detached from the layers farthest from the needles by which they are inserted, and are retained in the layers nearest said needles, each layer thereby containing a line of loops or tufts of thread and said lines being identical with each other. A lower driven shaft 34 is connected by a vertical shaft 55 and gearing to an upper shaft 1. Shafts 1 and 34 carry crank discs 2 and 37 coupled by connecting rods 3 and 38 to vertically reciprocating heads 4 and 39 which carry needle bars 8 and 48 for an upper needle 59 and lower needle 60. Heads 4 and 39 are coupled by links 10 and 42 to slides 11 and 44 adapted thereby to reciprocate on fixed horizontal rods 24A and 47B. A crosshead 13 is vertically slidable in slide 11 and is also horizontally slidable in a clamp 15 fixed to a presser bar 16 carrying a presser foot 22. Crosslead 13 carries a looper 14 adapted to cooperate with needle 60, and the arrangement is such that when the presser bar is lifted, by a lever 20 against the bias of a spring 18, looper 14 is also lifted.

Abstract: 524,207. Filling bottles &c. GREINER, C. F., and LIQUID CARBONIC CO., Ltd. Jan. 24, 1939. No. 2434. [Class 125 (ii)] Apparatus for filling bottles &c. with carbonated liquids &c. in the absence of air, in which the pressure in the container is initially slightly less than .the pressure tending to deliver the liquid thereinto but after partial filling is reduced to accelerate the liquid flow, comprises a filling tank 5 and filling tubes 9, Fig. 2, slidably supported on each of which is a housing 27 adapted to contact, by a gasket 29, with the container, and having in its upper part a pressure chamber 30, and at its top a seat 31 to receive the end of tubes 18 and a seat 32 which engages a gasket 33 on a neck 16. The container is raised in engagement with gasket 29 and housing 27 is raised until seat 32 contacts gasket 33. Simultaneously the lower end of tube 18 engages seat 31 and movement of housing. 27 raises valve so admitting pressure to chamber 17, and thence through tube 18 and chamber 30 to the container, the gas passing between seat 32 and tube 9. This pressure builds up in passages 25, 24 'and the pressure chamber 13 above diaphragm 12 brings stem 11 down to open valve 10 and permit liquid to flow from tank 5 to the container. A rotatable water-sealed, tube 34, Fig. 1, is carried by a support 3 and has a central rotor portion 36 with ports 44, one for each filler valve. Within tank 34 are cylinders 37, 38, the top of the latter constituting a counter-pressure stator valve 39 having a groove 41 communicating by ports 40 with cylinder 37. Ports 42 extend to a groove 43 in the stator and also communicate with cylinder 38. Co-operating with rotor valve member 36 is a vacuum valve stator head 46 having a port 47 connected to a vacuum producing means. Port 47 communicates with a groove 49 in the stator which during rotation of rotor 36 communicates at appropriate times with ports 44, of the rotor 36. Pressure carbon dioxide is admitted to water tank 34 and cylinders 37, 38 through a coupling 5d, pressure between tank 5 and tank 34 being equalized by a connection 52; this pressure maintains the water level in tank 34 at a predetermined point with both cylinders 37, 38 empty, the pressure being higher in cylinder 38 owing to its increased length than in cylinder 37. Rotation of cylinder support 3 opens valves 20 and produces vacuum in the container; continued rotation places cylinder 38 into communication with the container at a pressure less than that tending to cause exit of liquid from tank 5. The building up of this pressure actuates diaphragm 13 and opens valve 10 which admits liquid from tank 5 against the pressure in the container. When port 44 passes from groove 43 to groove 41 the container is in communication with the low-pressure cylinder 37 and filling is rapidly completed.
