Title: Improvements in or relating to superheaters
IPC: F22G5/02
Filed: 1919-10-20
Abstract: 140,713. Yarrow, H. E. Oct. 20, 1919. Overheating of superheating-tubes, preventing. -In a steam-generator provided with a superheater, means are provided for automatically controlling the temperature to which the superheater is subjected, dependent upon the difference of steam pressure between the inlet and outlet of the superheater. The superheater tubes E, Fig. 1, are shown in connexion with a Yarrow boiler having a steam drum A and water drums B, B<1>. An oil burner G is supplied with oil through a tube H, which is controlled by a regulating piston valve K. The rod K<1> of the piston K may be in alinement with, or connected to, the rod M<1> of the piston M, which works in a cylinder L, and may be pressed downwards by a spring P. The upper and lower sides of the piston M are connected by pipes N, O to the outlet and inlet ends of the superheater respectively. When the amount of steam flowing through the superheater is insufficient to prevent overheating of the tubes, the pressure difference on the two sides of the piston M is insufficient to prevent the downward movement of the piston M and consequently the piston K, and the supply of oil from the pipes I to the pipe H is cut off. If the piston-rods M', K<1> are not rigidly connected, the restoration of the oil supply is effected manually. The piston K may be arranged to cut off the oil supply only partially instead of completely, so as to maintain a sufficient temperature, especially when there are several burners G, in which case some of the burners are left unaffected. In a modification, Fig. 2, the control piston M operates a valve Q controlling the passage from the lower side of the leaky piston K to the relief pipe K<0>. When the valve Q is opened on a decrease in the pressure difference at the two ends of the superheater, the pressure in the oil-supply pipe I forces the piston K down and closes the valve R leading to the pipe H and thence to the burners. In another modification, Fig. 3, the piston M is maintained by the steam pressure in its highest position, where it closes the valve Q' and interrupts the passage of steam from the pipe N to the pipe S‹ and thence to the cylinder U. When the pressure difference on the two sides of the piston M falls to a predetermined value, the valve Q<1> opens, and the piston T is forced down, thus closing the valve K. In another modification, the two ends of the superheater are connected to the supply and exhaust of a Pelton wheel which drives a pump which supplies the oil to the burners. The supply of oil is thus varied according to the pressure difference of the steam at the two ends of the superheater.

Title: Method of producing artificial threads and like articles from viscose
IPC: D01F2/06
Filed: 1955-09-15
Abstract: Filaments, films and like products of regenerated cellulose consisting entirely of skin are produced by extruding viscose containing about 0.1 to 4 per cent, preferably 0.3 to 2 per cent, based on the weight of the cellulose in the viscose, of an alkylene oxide adduct of tall oil, of its extracted acidic components or of its extracted hydrogenated resin acid components, into an aqueous bath containing about 10-25 per cent, preferably 15-22 per cent, of sodium sulphate, 3-15 per cent, preferably 4-9 per cent, of zinc sulphate or the water-soluble sulphate of another heavy metal, and sulphuric acid, the sulphuric acid content of the bath exceeding the slubbing point but being below the concentration at which neutralization of the caustic soda of the viscose is so rapid as to produce products consisting of skin and core.  Each molecule of adduct may contain about 6-75 or more ethylene oxide units, preferably 10-30 ethylene oxide moles. per mole. of tall oil.  The adduct may be added at any stage in the production of the viscose, e.g. it may be added to the cellulose material used for the preparation of the viscose.  It is preferably added, however, after the solution of the cellulose xanthate in dilute aqueous caustic soda solution.  The temperature of the spinning bath may be 25-80 DEG  C., preferably 45-70 DEG  C. The sodium chloride salt test of the viscose should be above about 8 and preferably above 9 when the viscose is spun.  In an example, viscose containing 7 per cent of cellulose, 6 per cent of caustic soda, 41 per cent (based on cellulose) of carbon disulphide and 0.3 per cent of an ethylene oxide-tall oil adduct containing 16 ethylene oxide units per molecule is spun at 10.3 salt test into a spin bath at 60 DEG  C. containing 7.5, 8.0 and 18 per cent of sulphuric acid, zinc sulphate and sodium sulphate respectively. The filaments thus formed are then stretched 82 per cent in water at 95 DEG  C., washed and dried.  Small proportions of the adducts may also be added to the spin baths.

Actuating by compressed air; regulating delivery.-A mechanically-driven pump 30 feeds the chamber 18 of a fuel injection pump for an internal-combustion engine, the supply being delivered to an injection nozzle in the engine cylinder. A conduit 11 transmits the engine compression pressure to a chamber 14 to actuate the injection pump. The pressure ratio of the plunger 16, 17 may be varied by exchanging the delivery plunger 17 or the plunger unit, Fig. 7, for one having the required diameter on the delivery side, a removable adapted sleeve 17<1> being provided for this purpose. In a modified construction, the pump supplying the injection pump is eliminated, the plunger 16 of the injection pump being returned by a spring during the suction stroke of the fuel delivery plunger 17. In a further modification, Fig. 7, from which the fuel supply pump is eliminated, the injection pump is separated from the injection valve casing 3, the compression pressure being transmitted through a pipe 42 containing a regulating valve 43. Fuel is admitted to the injection pump by a mechanically operated valve 32 actuated bv coupled levers 46, 44, connected to the plunger pump, the quantity of fuel admitted being regulated by adjusting the valve opening by an eccentrically mounted lever pivot 47.

Abstract: 158,328. Rohman, H. D. Oct. 29, 1919. Addition to 145,120. Systems of charging galvanic batterics. - Relates to electric installations for lighting, heating, or ventilating railway carriages, or for similar purposes, in which axle-driven dynamos and storage batteries are employed. The invention is a modification of that comprised in the parent Specification. The dynamo A, which has a slipping belt drive, is connected to an automatic cut-in and cut-out switch D, storage battery B, lamps or other translating devices C and automatic charge-reducing switch E, all as in the prior specification referred to. The present invention employs a device F which comes into action after the charge-reducer under the influence of a shunt coil 6, closes contact 19, 20 and short circuits a part 21 of the resistance that was previously brought into use by the charge reducer. The effect is to divert so much more power into the resistance shunt that the battery "floats" across the terminals of the dynamo. Specifications 7470/10 and 114,332 also are referred to.

Class 108(3) A dynamic vibration damper comprises a pivotally mounted lever 30 carrying a weight 34 at its free end, and resiliently held against displacement by a spring 24, and having a dashpot 36 to control the amplitude of oscillation. As applied to the suspension of the rear axle 4 of a motor vehicle, the weight 34 is held by a torsion bar 24 extending between a bracket (not visible in Figs. 1 and 5) rigid with the axle 4 and a position adjacent the pivot of the lever 30. The damper serves to restrict high frequency vertical oscillation of the axle 4, which is suspended from the vehicle chassis frame by a coiled suspension spring 6. In a modified form of the shock absorber 36, a piston 46 (Fig. 5) operates in a pneumatic cylinder 42 having an external by-pass pipe 60 incorporating a flow restriction. The connections 56, 58, of the by-pass with the cylinder 42 are arranged so that they may be cut-off at the end of the respective direction of piston movement so as to produce a cushioning effect.
