Title: Improvements in or relating to cigarette making machines
IPC: A24C5/18
Filed: 1931-04-28
Abstract: 372,088. Cigarettes ; cigarettemaking machines. MOLINS, D. W., Longwood, Hurst Road, Bexley, Kent. April 28,1931, No. 12499. [Class 130.] Cigarettes with tobacco packed more closely at the ends than in the middle are cut from a continuous rod along which alternate rare and dense sections are formed by displace. ment. The denser parts are spaced apart a distance equal to one or two cigarettes. As shown in Fig. 3, paper 8 is fed from a reel 7 through a printer 9 and afterwards through a trough 5, where tobacco from a hopper 4 is deposited in a uniform layer on the paper. A tape 10 carries the loaded paper beneach a compression wheel 16 into a rodforming and gumming mechanisms 11, 12 and past a heater 13 to a cutting mechanism 14. Variations in density of the tobacco are produced in the rod (1) by rotating the compression wheel at a variable speed, or (2) by raking part of the tobacco backwards with pins 28, Fig. 7, actuated by a cam 29 and carried by the wheel 16. To ensure that the rod is cut at the points of maximum density the compression wheel and the cutting mechanism are driven in synchronism through gearing 21 .. 24.

Title: Polymeric lubricating oil additives
Inventor: FORD JOHN FRERERICK
IPC: C08F8/12
Filed: 1963-03-29
Abstract: A lubricating composition consists essentially of a major proportion of a mineral or synthetic lubricating base oil and a minor proportion (0.1-25%, more specifically 1-10%, by weight of the composition) of a liquid polymer containing phosphorus and oxygen made by reacting an olefin with phosphorus halide to produce a phosphohalogenated polymer and then hydrolysing to convert the halogen into oxygen or hydroxyl groups.  The olefin may be 4-methylpentene-1, and the hydrolysed polymer may be neutralized with excess barium hydroxide, or , in general, with a hydroxide, oxide or alkaline-reacting salt of an alkaline earth metal, alkali metal or aluminium.ALSO:Liquid polymers containing phosphorus atoms and oxygen are made by a process which comprises reacting 100 mols. of an olefin with 0.1 to 25 mols. of phosphorus halide in the presence of at least 1.5 mols. of a Friedel Crafts catalyst per mole of phosphorus halide at a temperature below 0 DEG C. so as to produce a phosphohalogenated polymer which is then hydrolysed to convert the halogen present into oxygen or hydroxyl groups.  This product may then be reacted with a basic compound.  In the examples, 4-methylpentene-1 is reacted with phosphorus trichloride and aluminium chloride in solution in methylene chloride. Hydrolysis is carried out with water in carbontetrachloride. In one example, the hydrolysed polymer is dissolved in heptane and further reacted with barium hydroxide.  The products find use as lubricating oil additives.

Abstract: 474,752. Electromagnetic switches and interrupters. LUCAS, Ltd., J., and LAIRD, J. A. May 5,1936, No. 12664. [Class 38 (v)] In a dynamo regulator of the vibratory type, the armature is provided with a supplementary controlling spring, the anchorage of one end of which is free when the regulator is inactive, but is secured by electromagnetic means when the regulator is active, the object being to render the action independent of wear or other variation of the contacts. The armature b carrying contact c is subjected to the action of the main spring e and bears on a curved abutment h, so shaped that the pull of the spring is always approximately equal to the effort exerted by the electromagnet a, f. The supplementary spring is connected at one end to the armature b, the other end being free except when it is gripped between the resilient bracket p and the polepiece t by the contacts m, n of the cut-out when the dynamo attains sufficient speed. Specification 423,739 is referred to.

[Class 123 (ii)] [See also Group XII] Thimble-tube boilers are fitted with a gas distributer which byepasses some of the entering hot gas and prevents it giving up its heat to the tubes near the gas inlet but delivers it without heat loss amongst the rows of boiler tubes nearer the gas exit. The distributer may comprise a series of discs 30.. 32 extending transversely of the direction of gas flow and so perforated that the hole area decreases from disc to disc. In the form shown, disc 30 has 8 and disc 31, 4 holes, whilst 32 is imperforate. The bottom disc is preferably made of refractory fire brick when oil burner firing is employed, the others being of cast haematite heat-resisting iron.

IPC: C08B1/08
Filed: 1958-04-24
Abstract: Cellulose is treated with sodium hydroxide solution at a temperature of at least 50 DEG C. and excess sodium hydroxide is removed from the cellulose at the same temperature.  Preferably cellulose webs are unwound from supply rollers and continuously drawn through 19% sodium hydroxide solution at a speed of 0,1-3 metre/minute at a temperature above 50 DEG C., excess sodium hydroxide solution being removed by passage of the web between squeeze rolls exerting low pressure, e.g. 45 kg./cm2, also at a temperature above 50 DEG C.  A vessel containing sodium hydroxide solution, through which cellulose is to be passed, may have its base closed by a pair of rollers, or a series of pairs of rollers if more than one cellulose web is to be treated simultaneously, the web(s) being conveyed downwardly.  Wetting agents, oxidizing agents, catalysts and other additives may be added to the sodium hydroxide solution.  The cellulose webs may decrease in thickness at both edges.

Filed: 1929-04-29
Abstract: 325,169. Pehrson, A. P., and Lloyd, F. April 29, 1929. Cores.-In the manufacture of hollow metal rods &c. by reducing hollow billets, blooms, or ingots, as by rolling, forging, or drawing on an austenitic steel or other metal core, one or both ends of the core is or are extended beyond the end or ends of the billet and formed with enlarged ends of such a shape that the billet during the reducing operation passes freely over the surface of such end or ends without encountering any appreciable resistance to its elongation. End waste is thus reduced. The enlarged end C of the core is of tapering bulb form gradually merging into the main portion so that no shoulder is present, thus avoiding a constriction or actual rupture of the core. The enlarged end of the core retains its heat longer and thus assists in preventing constriction or rupture. One or both ends may be formed after insertion in the billet.
