Filed: 1920-07-07
Abstract: 160,432. Helmbold, P. A. Feb. 16, 1920, [Convention date]. Combing-machines. -The comb cylinder of a Heilmann or like combing machine having swinging nippers which remain almost stationary whilst the comb is in action has imparted to it a variable velocity in such a manner that the comb moves more slowly as it encounters the resistance of the fibres and more quickly when the combing is taking place. The comb cylinder shaft a, Fig. 1, may have mounted upon it a loose uniformly driven gear c carrying on studs d gears e engaging a fixed gear i. Eccentrics f are formed on the gears e, and the straps g of the eccentrics are connected to lever arms h keyed to the shaft a. The desired variation in speed may be obtained by driving the shaft through eccentric gears. The Specification as open to inspection under Sect. 91 (3) (a) comprises also arrangements in which (a) the studs d carry toothed segments rocked about the studs by arms engaging a stationary cam, the segments engaging a gear fixed on the comb shaft, and the arms moving relatively to the segments against the action of springs to allow the comb to yield to sudden resistances to the movement of the comb; and (b) the comb is connected to its shaft through a spring coupling, or (c) the individual comb segments are arranged to yield, so that the resistance to movement due to passage through the tuft being combed will produce the desired variation in speed. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in the manufacture and production of metal carbonyls
IPC: C01G1/04
Filed: 1929-06-24
Abstract: 334,976. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). June 24, 1929. Drawings to Specification. Metal carbonyls are made by reaction of carbon monoxide with carbonyl-forming materials in a plurality of separate reaction vessels, through at least two of which, either the gases or liquids containing carbon monoxide, or the carbonylforming materials, or both, wholly or in part, are passed in series. Said materials may be in solid form, or in the presence of inert liquids or melts as described in Specification 323,332. The carbon monoxide may be passed through a series of charged reaction vessels, fresh gas meeting the most exhausted material first until reaction ceases, when the vessel is cut out, emptied and recharged with fresh material, and re-inserted as the last of the series. The velocity of the gas stream is preferably adjusted so that no carbon monoxide remains after traversing the whole series, and pure, metal carbonyl can be separated. Alternatively the solid, pasty, or suspended material may be conveyed through the series by means of connecting passages, which may be insulated or cooled and bent at their ends to prevent the passage of gas, by forming a liquid seal. Somo or all of the vessels may be arranged at different levels, or in horizontal or inclined positions, and the direction of flow may vary. Liquids, such as carbonyls or inert diluents, may be added or withdrawn between the vessels. The gas may be passed in the same direction or in counter-current, and may be used to stir the suspensions and separate fresh from exhausted material, according to its specific gravity. In an alternative method for transferring both gas and solid, the vessels are arranged one above the other with sluices between. The gas is passed into the bottom of each vessel, and thence led to the vessel above. The top vessel is periodically emptied into the one below and freshly charged, or two vessels may be arranged for alternate use to make the process continuous. The second vessel is discharged into the next and so on, until exhausted material is finally removed from the bottom one. The, top vessel after emptying may be filled with liquid carbonyl before releasing the pressure.

Title: Tobacco smoke filter
IPC: A24D3/16
Filed: 1965-05-07
Abstract: A tobacco smoke filter comprises synthetic filaments, activated carbon particles and a high molecular weight (i.e. between 600 and 20,000) polyalkalene glycol.  Preferably the polyalkalene glycol is a polyethylene glycol, a methoxy polyethylene glycol, or a propylene glycol.  The activated carbon particles have a mesh size (U.S. Standard) of 10-325, preferably 10-45, and the filter may contain from 2 to 200 parts by weight of carbon particles and from 2 to 25 parts by weight of glycol per 100 parts by weight of filaments. Suitable synthetic fibres are cellulose acetate tow or yarn having a total dernier of 25,000-75,000 and a dernier per filament of 1-16. Flavourants may be included in the filter.  The filters, which may be used in series with conventional filters, may be prepared by spreading the fibres and coating them, e.g. by spraying, with the polyalkalene glycol, after which the carbon particles are applied to the coated fibres.  Before the glycol has solidified the fibres are formed into a rod.  Quantitative examples are given.

Title: Granular materials
Inventor: PALMER ROBERT WILSON
IPC: B01J2/12
Filed: 1954-07-03
Abstract: In the granulation of ammonium salts, nitrates or urea by subjecting the material to heat treatment and agitation in an atmosphere the moisture content of which is in the range of 30 per cent. humidity to supersaturation, the water content of the initial material is adjusted to that necessary to induce incipient nodulation, which is defined as being a water content such that upon agitation alone at room temperature by conventional granulating means, the particle size of the material would be increased but not to such a degree as to form a granule of 1 mm. diameter.  After subjecting the material to heat treatment and agitation the granular product may be dried and thereafter cooled. The heat treatment is preferably effected at 70 to 110 DEG C. and the hot treating gases preferably flow in countercurrent to the material to be heated, either in a rotary furnace or if desired in a fluidized bed.  The material treated may be ammonium sulphate nitrate, with or without fillers or carriers or mixed fertilizers containing superphosphates or other phosphates together with ammonium sulphate nitrate, calcium nitrate or urea. According to an example, material consisting of ammonium sulphate nitrate, ammonium sulphate, potassium chloride, superphosphate and triple superphosphate was adjusted to a moisture content of 4 per cent. by weight (which is sufficient to induce incipient nodulation as defined above), and was fed to a rotary drum through which hot gases having an inlet temperature of 375 DEG C. passed in countercurrent flow.  The relative humidity of the exit gases was controlled at 47 by the injection of steam into the hot inlet air-stream.  The exit granule temperature was 103 DEG C. and the product granules, predominately of a size between 4,5 and 1,5 mm., had a moisture content of 2 per cent.  The required initial moisture content may be attained by the addition of water or by the selection of the components of the mixture so that the required water content is attained.
