Title: Modulated electric arc for chemical reactions
IPC: B01J19/10
Filed: 1953-08-12
Abstract: <PICT:0751735/III/1> <PICT:0751735/III/2> <PICT:0751735/III/3> An apparatus for treating chemical substances with an arc to obtain cracking or synthesis thereof e.g. for the production of gasoline from fuel oil and hydrogen comprises two co-axial conical electrodes 5, 15 electrically insulated from one another.  The cone 15 has at its base a device 6 producing sonic or supersonic waves and at its apex a pile 8 of annular metal elements assembled in imperfect contact with each other and heated by passage of current therethrough so as to emit electrons.  A metal cylinder 17 exposed to electro-magnetic action is arranged coaxially around the metal elements 8 and is formed with cavities 17a on its inner part to form a cavity magnetron.  A metal rod 4 has a mushroom head 9 resting on the metal elements 8 through which a low tension current is passed from a source 21 connected to the base of the cone 15 and to the rod 4.  A high tension source comprising a variable transformer 20 is connected to the rod 4 and to the cylinder 17 and passes through a rectifier 24 so that the cylinder 17 is at positive potential.  An annular arc is thus created between the cylinder 17 forming a magnetron anode and the metal elements 8 forming a cathode emitting electrons around the arc. Current is passed from a variable transformer 27 through a rectifier 28 and condenser 29 to a helical coil 26 surrounding the ring 17 thereby completing a magnetron.  Fuel oil introduced at 7 is finely divided by the supersonic waves from the device 6 and passes between the metal elements 8 into the arc. Hydrogen is introduced through tangential holes 30 in a metal cone 14 surrounding and spaced from a dielectric cone 13 on the electrode 15, whereby a whirling motion is given as it mixes with the fuel oil in the arc.  Gasoline thus formed is delivered through the conical electrode 5, which may taper inwardly or outwardly.  The ring 17 is insulated from the cones 5, 14 by rings 18 of insulating material. In Fig. 3 an arc between an electrode 38 and a venturi cone 36 supplied by a Ruhmkorff coil 32 is modulated by an impedance 35 connected to the narrowest part of the venturi cone from one terminal of the coil, the other terminal of which is connected through a double solenoid 37 to the electrode 38, and a variable condenser 40 is connected in the circuit as shown.  The electrical characteristics of the apparatus may be varied for various chemical reactions e.g. for synthesis or for cracking. Several units of the apparatus may be connected in parallel or in series.

Patent GB-407673-A (GB)
Title: Improvements in the manufacture of films, sheets and the like containing cellulose derivatives
IPC: C08L1/08
Filed: 1932-08-13
Abstract: When coagulating cellulose ester and ether films, sheets, foils &c., transparent, smooth and easily detachable products are obtained by employing a coagulation bath with which a solvent or latent solvent of the film-forming solution has only a limited miscibility, and removing the film from the bath whilst it still contains a substantial proportion of such solvent or latent solvent.  The liquid used for the preparation of the film forming solution may be a solvent, or a mixture of solvents, or a solvent mixture, although true solvents are preferred.  If acetone or other water-miscible solvents are employed, the coagulation bath conveniently comprises a hydrocarbon; if a halogenated hydrocarbon or other hydrophobe solvent is used, an aqueous coagulation bath may be employed.  The miscibility of the solvent with the coagulation bath may be still further reduced by dissolving in the latter salts, sugars &c., according to Specification 343,062, or by adding to the bath a proportion of the solvent; on the other hand the miscibility of the solvent with the coagulation bath may be increased somewhat by adding to the latter a substance miscible with both, and if desired the miscibility may increase during the travel of the film through the bath as by adjusting the composition of the latter.  The band, drum &c. on which the film is carried may be positioned in proximity to the orifice at which the film is formed or at some distance therefrom; the coagulation bath may contact with both sides of the film as in Specification 405,692, for example, by extruding the film into the coagulation liquid; or the film may be extruded on to a supporting band, drum &c. on which it is spread by means of doctor blades &c. or by utilising the rear lip of the extrusion slit, or by means of a roller.  A convenient apparatus comprises a drum, the lower part of which dips into the coagulation liquid, the pin-forming solution being applied by means of a doctor blade to the upper descending half of the drum; the film may be dried on the ascending side by means of a heated segment.  The solvent carried by the film may be removed by evaporation as by drying on a smooth surface, or by washing, the rate of removal of the solvent being preferably restrained, either in a separate bath or by means of a layer of liquid on top of or below the coagulation bath, through both of which the film passes in succession.  A stretch may be applied to the film during its formation, for example, as described in Specification 400,589.  If the solvent retained in the film is more volatile than the non-solvent of the coagulation bath, a milk white film is obtained by simple drying. Specifications 340,324, 341,148, 356,343, 375,423, 375,424 and, in the Provisional Specification, 405,676 also are referred to.

Abstract: 1,169,832. Data selecting apparatus. EASTMAN KODAK CO. 15 May, 1968 [22 May, 1967], No. 22979/68. Heading B6E. [Also in Divisions G2 and G5] Apparatus for positioning in an operational station 95 a predetermined area such as 14 of a selected strip S from a plurality of strips arranged in shingled array in a holder 12 includes movable scale 13 which slides in response to the selection of a strip to compensate for the relative displacement between corresponding areas such as 14 on successive strips S. The required strip S is selected by a knob 37 which rotates a helical cam 66<SP>1</SP> and thereby slides a plate 70 along a rod 73, Fig. 7, which effects rotation of a strip selector member 87 through a cable 115 fixed at one end to the member 87 and at the other to the body ofthe apparatus and passing around a pulley 113 mounted on a lever 111 pivoted to the plate 70. The motion of the plate 70 moves the pulley 113 and thereby effects rotation of the selector member 87 which selects the required strip (S 5 ), Fig. 11 (not shown) by two lips (93, 94) between which is an opening (92) for the strip. The scale 13 is also fixed to the plate 70 so that selection of a strip effects compensating movement of the scale, an L- shaped slot 76, 77 in the plate 70 defining the starting point for a strip moving member 35 which is operable to select the required area I 4 . An interlock device comprising a detent 130 engageable with a fluted portion 68 of a drum 66 which carries the cam 66<SP>1</SP> prevents rotation of the strip selector member 87 while an area I 4  is in the operational station 95. A further lock comprising lugs 141, 142 acting on members 51, 52 prevents the removal of the holder 12 while an area I 4  is in the operational station. The operational station may be a projection lens system, or a magnetic scanning device (not shown).
