Title: Method and apparatus for the manufacture of small articles or pellets from paste material
IPC: B01J21/00
Filed: 1955-01-14
Abstract: 775,599. Moulding pellets of catalytic material &c. ROSIN, S. N. Jan. 14, 1955 [Feb. 3, 1954], No. 1218/55. Class 87(2). Paste material to form pellets such as catalyst bodies is extruded through one or more rows of orifices 2, of circular or other shape, in a thin conveyer band 1 by a pump or by a screw 15 which is mounted in an internal chamber 9 of a drum 3 over which the band 1 passes. The orifices 2 connect with an annular chamber 10 connected to the chamber 9 by radial orifices 11. A closure member 16 seals off the part of the drum not in contact with band 1 and acts as a scraper for the underside of the band. The orifices 2 are of short axial length compared with the pellets. The extruded pellets are carried, in the orifices of the band, through a drying tunnel 6 and over a drum 4 where the flexure of the band, aided by doctor 7, removes the pellets from the band. In a modification, Fig. 5, the drum 3 is replaced by a stationary extrusion head 19. The return lap of the band 1 may pass through a bath 20 of cleaning fluid and through a wiping means 21. The band may be of greater thickness than above specified, Fig. 4a, and the orifices formed, as at 2a, with tapering side walls 2b. The pellet size is controlled by varying the extrusion pressure, the speed of the band 1, or by varying both together. The pellets may contain a volatile vehicle, when in the paste stage, to ensure an increase in the porosity thereof ; or the paste may contain an included gas which is withdrawn on passing through a drying zone of reduced pressure.

Soluble synthetic resin patterns 13 are secured to a wax or synthetic resin support 12, invested with refractory material 15 and removed from the shell by removing the support 12 to expose a portion 16 of the pattern assembly and thereafter allowing a solvent for the pattern material to contact at least the exposed portion of the pattern assembly for a time sufficient to dissolve or soften the pattern material to such an extent that expansion of the material when heated will not damage the shell, and finally heating the shell to volatilize any remaining pattern material. The pattern assembly is dip-coated and some coats may be applied after removal of the pattern. The pattern support is of wax or synthetic resin formed on a metal former 11 which is removed to allow the wax or resin to be melted or dissolved. The solvent may be for example methyl ethyl ketone or trichloroethylene.

Abstract: 200,850. Price, S. L. Jan. 17, 1922. Vehicle lamps.-The dazzle of a two-filament lamp used with a reflector for motor-car headlights is reduced by causing the light from one filament wholly or partially to flood the reflector with coloured or diffused light while substantially the whole of the light from the other filament is projected as a concentrated beam unmodified as to colour or diffusion. The main filament D, Fig. 1, is placed at the focus of the reflector F and the auxiliary filament E is removed therefrom and enclosed in an inner coloured bulb C in the main bulb A. The filaments may be connected in series or parallel and arranged for alternative use, and if means are provided for moving them relatively to the focus the character of the emergent beam may be modified. Fig. 3 shows an auxiliary filament E in series with the main one D and enclosed in a coloured sleeve C and in an alternative arrangement the main filament surrounds an internal coloured tube in the bulb which tube encloses the auxiliary filament. In the form shown in Fig. 6, the auxiliary filament E is contained in a bulb C formed externally on the main bulb A. The enclosure of the auxiliary filament may be of amber or other colour, or it may be of frosted or opal glass.

Abstract: 881,750. Baffles. HEURTEY & CIE. Jan. 16, 1958 [Jan. 18, 1957], No. 1515/58. Class 51 (1). [Also in Group XI] In a liquid fuel burner of the type described arid claimed in Specification 822,776, wherein a mixture of fuel and a combustion-supporting agent, e.g. air is met just past the point where said mixture is formed by a recycled current of products drawn from the area where combustion is initiated and of the type from which the combustion gases escape at high velocity, a deflector is placed at a small distance from the burner outlet and is suitably shaped to give the required direction of the ejected gases. As shown the burner 1 is mounted in a hole in the wall 2 of an oven which hole takes the small dimensioned fire-proof block 4 containing the combustion chamber of the burner. The outlet orifice 5 of the burner terminates a converging fuel passage which increases the velocity of the burning mixture to strike against a deflector 6, shown as of prismatic form, located with its leading rounded edge 7 in a plane symmetrical to the orifice 5, within the orifice 8 bounded by the lateral walls 9 of the block 4 and diverging facets 10 which are parallel to the inner facet of the deflector 6. The deflector produces a spreading of the combustion gases along the inner surface 11 of the wall 2 into two vertical jets. The edges of the deflector may be disposed vertically to produce a horizontal flame spread or the deflector may be conical with its smaller end facing the outlet 5 to produce a circular spread. The deflector may take the form of a plate provided with perforations the location and orientation of which being selected according to the spread of flame desired.

Filed: 1918-01-31
Abstract: 122,498. Haworth, W. N., and Irvine, J. C. Jan. 1918. Dimethyl sulphate is prepared by the reaction of sulphur trioxide on dimethyl ether in the presence of a solvent or diluent, preferably dimethyl sulphate itself. The sulphur trioxide used is preferably diluted with an indifferent gas; thus a current of air may be passed through hot fuming sulphuric acid and the resulting mixture of air and sulphur trioxide used, or the mixture of air, sulphur dioxide, and sulphur trioxide resulting from the contact process of making sulphur trioxide may be used. The product of the reaction is treated, either with ice or preferably with a reducing-agent such as iron filings to destroy any sulphur trioxide present and is purified by distillation in vacuo.
