Title: Improvements in or relating to devices for delivering controlled quantities of liquid for vaporisation
IPC: A61L9/03
Filed: 1962-03-08
Abstract: 993,884. Device for vaporizing liquids. FRAGRANCE PROCESS CO. Inc. March 8, 1962 [March 14, 1961], No. 9039/62. Heading A5G. A device for vaporizing a controlled quantity of liquid comprises a reservoir containing such liquid, a beaded chain, means adapted to advance the chain at a controlled rate through the reservoir so that the chain traps liquid between adjacent beads, and a heating element effecting controlled vaporization of the liquid delivered to said element by the chain. The Figure illustrates a transverse section of a device according to a preferred embodiment of the invention. The reservoir 50 is provided with a threaded opening in which is positioned a container or bottle 56 filled with a vaporizable liquid 58 which is advantageously a scented liquid, which liquid also fills the interior of the reservoir. The beaded chain 72 is trained to pass over the heating element 76, in the form of an incandescent bulb, the element being surrounded by a deflector plate 78 which deflects droplets 82 of the liquid into a vaporizing pan 80. The speed of the chain is controlled by a motor which drives the sprocket wheel 38, the motor being regulated by means of the timing control knob 44.

A high-efficiency amplifier comprises a transistor 1, Fig. 1, operated in class C and having as collector load a first circuit 5, tuned to the drive frequency and from which the output is taken, in series with which is a second circuit 6 tuned to the third harmonic frequency. In addition, the collector circuit may include further series-connected circuits tuned to higher harmonics. The angle of conduction is made 120 degrees, as shown by biasing the base back from source 4 and driving with a sine wave derived from source 2 via tuned transformer 3. Alternatively, the bias source may be dispensed with, a circuit tuned to third harmonic frequency being included in the base lead, or a square-wave drive may be employed (Figs. 2, 3, not shown). In a push-pull embodiment a pair of transistors are driven from a transformer with a centre-tapped secondary and drive into a transformer with a centre-tapped primary, each collector lead including a circuit tuned to third harmonic frequency (Fig. 5, not shown). In another push-pull embodiment, a pair of transistors 1, 1<SP>1</SP>, Fig. 6, of opposite conductivity type are connected in series, the bases being driven from separate secondary windings on the input transformer 10. The collectors are connected together and via circuit 6 tuned to third harmonic frequency and blocking condenser 12 to output circuit 5, tuned to the drive frequency. In an alternative arrangement the load circuits are connected between emitter and earth (Fig. 8, not shown).

Abstract: 1392667 Olefin polymer fibres MONTECATINI EDISON SpA 26 Feb 1973 [25 Feb 1972 30 Jan 1973 1 Feb 1973] 9258/73 Heading B5B [Also in Division D2] Olefin polymer fibres suitable for use as pulp in paper-making are made by ejecting a solution of an olefin polymer as a jet, and hitting the jet of of solution with a jet of fluid, the jets suitably being inclined to each other at 30-90 degrees. Polyethylene, optionally containing minor proportions of copolymerized monomers, and isotactic polypropylene are preferred, and the solution may also contain a polymer containing polar groups. Specified fluids include water, air, steam, carbon dioxide, nitrogen and oxygen, and the speed upon impact of the fluid jet may be 200 to 600 m/s. The polymer solution which may contain a surfactant may be ejected into the ambient atmosphere, suitably at a speed of 1,000 to 2,000,000 m/h. Preferred solvents include heptane, hexane and trichlorofluoromethane, (many others are listed); desirably the temperature of the solution is at least 60 C. higher than the boiling temperature of the solvent under normal conditions, and the boiling point of the solvent should exceed the melting point of the polymer. In apparatus as shown, an olefin polymer solution is fed through pipe 1 into an autoclave 2 fitted with stirrer 3, and ejected as a jet through a nozzle 6. Hitting fluid is fed through a pipe 4 and a nozzle 5. The fibres fall into collection vessel 7. The nozzle is shown in greater detail in Fig. 2 (not shown). In an alternative embodiment the fluid may be in the form of a mass which is geometrically coaxial with the nozzle ejecting the polymer solution. Thus in Fig. 3, duct 11 for polymer solution is arranged coaxially inside a duct 12 for hitting fluid. Ducts 11, 12 respectively end with nozzles 13, 14. Frusto-conical chamber 15 allows the polymer solution to expand before being hit. Terminal zones 16, 17 of ducts 1, 2 are so shaped that the axis of the space 18 between them is inclined at an angle α to that of the nozzle 13. Examples illustrate the manufacture of polypropylene fibres from solutions in hexane, polyethylene fibres from solution in hexane, heptane or trichlorofluoromethane; and of fibres of a blend of polyethylene with either an ethylene-ethyl acrylate copolymer or polyvinyl chloride, both from hexane solution.

[Class 110 (i)] [Also in Group XXIX] A centrifugal supercharging compressor has a vaned diffuser and the inlet ends of the vanes are angularly adjustable. In Specification 590,300 adjustment of the inlet ends of the vanes is effected through a control device responsive to the ratio of the static pressure rises in the impeller and diffuser, respectively and operates to maintain the ratio constant. According to the present invention, the control device is modified to increase that ratio as the pivoted vane parts move to the limits of their adjustment. The movement of the pivoted vane parts 22 is effected by a lever 23 operated by a servo-motor 35, 37, 40 under control by a lever 31 which is subjected at opposite ends to the pressure rises in the impeller and diffuser. According to the present invention, the pivot 33 of the lever 31 is moved, to alter the ratio of the lengths of the two sides of the lever, by means of a cam 45 which moves with the connecting link 24 and thereby the ratio of pressures maintained by the control device is increased as the link 24, and consequently the pivoted vane parts, moves from its mid-position in either direction.
