Title: Improvements in and relating to paper-bag-making machines or the like
IPC: B31B19/62
Filed: 1926-06-08
Abstract: 277,262. Robinson, P. G., Sargent, T., and Strachan & Henshaw, Ltd. June 8, 1926. Paper bags, making. - Adhesive or paste is applied adjacent a folded part of a bag blank or other article by a paste-applying bar or member which receives a supply of paste from a carrying roll or member by removing paste therefrom in a series of contiguous lines or zones, the paste-carrying roll being advanced between the operations of the paste-applying bar only as far as is necessary to present a leading edge of paste to the bar, so that the paste-carrying roll returns a clean surface to the paste-box. Paste supplied by a box 19, Fig. 1, to a roll 16 is transferred to a blank between folding rolls 3, 1 by a bar 3<a> eccentrically mounted on the axle 5 of the roll 3, the arrangement being such that the bar 3<a> is thrust outwards to engage the roll 16 and is drawn inwards when it applies the paste to the blank and passes the roll 1. The paste is removed from contiguous zones on the roller 16 which for this purpose is rotated very slowly relatively to the roll 3. To effect this, a shaft 9, Fig. 2, from which the roll 3 is driven, is provided with a pinion 13 adapted to engage a pinion 26 loosely mounted on a stationary sleeve 27 on a stub shaft 28 operatively secured to the shaft of the roller 16. A planet pinion 29 in a housing 26a on the pinion 26 engages a pinion 30 fixed to the sleeve 27 and also a pinion 30<a> having one tooth less than the pinion 30. The pinion 30<a> is mounted on sleeve 27<a> which drives the shaft 28 through a coil spring 32. The tension of the spring 32 may be relaxed by a hand-wheel to permit angular adjustment of the roll 16. In a modification, the roller 16 is driven from the shaft 5 by a ratchet and pawl mechanism. The paste-box 19 and roll 16 are supported by a cradle 20 pivotally mounted on the shaft 9 and adjustable to raise or lower the roll 16 by an eccentric 22<a> on a shaft 22 connected to the main frame of the machine by a link 23.

Title: Improvements relating to the manufacture of steel
IPC: C21C5/32
Filed: 1959-04-24
Abstract: Steel is refined by surface blowing oxygen from a lance, the melt being stirred when oxygen blowing is stopped for intermediate or final deslagging by blowing a gas containing less than 35% oxygen into the melt.  The oxygen may be loaded with dephosphorizing agents, as may the gas, which can be nitrogen, argon, carbon monoxide, air or air enriched with oxygen with or without steam and/or carbon dioxide. Blowing the gas may take 1-4 minutes, the lance used for blowing oxygen being suitable therefor.  The process is applicable to rotary furnaces and to conventional bottom blown converters.  The feed of dephosphorizing material in the oxygen may be increased during the 2-3 minutes immediately before the cessation of oxygen blowing.

Abstract: 315,515. British Thomson-Houston Co., Ltd., and Davies, L. J. May 18, 1928. Imitation fires.-A flicker " effect for imitation fires or advertising appliances is produced by interposing in the path of light from a steady source a virtually opaque liquid, such as mercury or aniline, which is agitated, the disturbance of the liquid being utilized either to reflect or intercept the light in an irregularly intermittent manner. The agitation may be produced by boiling the liquid, or by movement of the containing vessel; when mercury is used, the vessel is sealed and evacuated, or filled with a non-oxidizing gas such as hydrogen under a pressure of about 1/3 of an atmosphere. Fig. 2 shows one form of the device, in which light from a lamp 5 is reflected from the surface of a liquid 2, which is boiled by an electric heater, on to a screen or imitation fuel surface 6. Lenses 7, 8 may be employed to produce an image of a transparency 9 on the screen. A concave, convex, or irregularly-surfaced mirror, or lenses giving chromatic aberration, may be interposed in the path of the light. In another form, a shallow layer of mercury is boiled in a vessel, the light from a, lamp placed beneath passing up through the spaces intermittently occurring due to ebullition. A third form comprises a narrow upright vessel, which may be curved in plan to embrace a, wide angle of light, in which the rising and falling of the upper surface of the wall of contained liquid irregularly obturates the light.

Filed: 1970-03-26
Abstract: 1286383 Refining lubricating oil stocks SUN OIL CO 26 March 1970 [3 April 1969] 14670/70 Heading C5E A lubricating oil fraction is extracted with a solvent having preferential solubility for aromatics, the raffinate is hydrocracked to increase its viscosity index, the hydrocracked oil is extracted with a solvent having preferential solubility for aromatics and the solvent extract phase, containing solvent and extract, from extraction of the hydrocracked oil is used for the extraction of the lubricating oil fraction prior to the hydrocracking. A feed 1, e.g. a vacuum distillate or residuum which can have been deasphalted with propane, is extracted at 2 with a solvent comprising the solvent and extract phase 10 from the extraction at 7 and additional extractive solvent 15. Solvent contained in the raffinate 3 is removed at 4 by distillation and the raffinate is then hydrocracked at 5. The hydrocracking is carried out at 650-825 F. with a hydrogen partial pressure of at least 1500 p.s.i. using a catalyst such as a mixture of nickel sulphide and tungsten sulphide on an alumina, silica or alumina-silica support, or palladium on a molecular sieve support. The hydrocracked oil is extracted in 2-10 stages at 7 with a solvent 14, such as furfural, phenol, acetophenone, acetonitrile, nitrobenzene, aniline, 2,2-dichlorodiethyl ether or dimethylsulphoxide, which can contain water. Solvent contained in the raffinate 8 is recovered by distillation at 9. The extract phase 12 from the solvent extraction 2 is treated at 13 to purify and recover the extractive solvent 14 and 15 and to separate a stream 16 of extracted oil and other impurities which can be cracked to gasoline or used as a rubber processing oil. In an example the feed 1 is vacuum distilled to produce a light vacuum distillate boiling from 775-855 F., a heavy vacuum distillate boiling from 855-955 F. and a residual oil boiling at 955 F. and above and which is deasphalted with propane. The heavy vacuum distillate and the deasphalted residue are separately extracted, the raffinates from these extractions blended with the light vacuum distillate and the blend hydrocracked. The hydrocracked material is extracted to produce an extract phase comprising extract and solvent, which is used to extract the heavy vacuum distillate and the deasphalted residue, and a raffinate which is distilled to produce a 100 neutral oil, a 200 neutral oil, a 500 neutral oil and a bright stock. Low asphalt feeds can be simultaneously deasphalted and solvent extracted by the Duo Sol process.
