Title: Improvements relating to the automatic regulation of the combustion of gaseous fuel in bunsen burners
IPC: F23D14/48
Filed: 1925-05-26
Abstract: 242,186. Lynn, J. May 26, 1925. Air supply, regulating; air supply for combustion; gas pipes.-The combus. tion of gas in Bunsen burners is automatically regulated by preheating, by means of the combustion products, the gas and the primary air, such regulation depending on the fact that the calorific value of the mixture varies directly with its density and therefore inversely with its temperature. Fig. 2 shows the application to a kitchen-range &c. A chamber 1, heated by the combustion products, is divided, by a partition 2, into two compartments. Air supplied by open pipes is heated in one and gas from a pipe 6 in the other mixture being effected at 8, 10. A wall of fire-brick &c. which may serve as backing for radiants 12 protects the chamber 1 from excessive heat. In a modification, Fig. 4, of less depth and suitable for a closed stove or for an open fire, the gas is heated by giving the gas pipe 6 a circuitous course through the air chamber. Reference has been directed by the Comptroller to Specifications 11903/01, 12606/09, and 11777/12.

Title: Plate assembly for stripping volatile components from mixtures of liquids and or particulate solids
IPC: B01D1/22
Filed: 1971-05-10
Abstract: 1337049 Vaporization of components from a liquid or fluidized solid mixture PARKSON CORP 10 May 1971 [15 June 1970] 14039/71 Heading BIB Volatile components are vaporized from a mixture comprising liquids and/or particulate solids by pumping the mixture from tank 10 to injector 22 where it is dispersed in a stream of stripping vapour (e.g. steam) supplied through conduit 24, this vapour stream then carries the dispersed mixture through the passageways of plate contactor 26 where the volatile components are vaporized. The effluent from contactor 26 flows to separator 30 where the two phases are separated, the mixture wholly or partly freed from volatile components being discharged through conduit 34, and the mixture of volatilized components and stripping vapours flowing out through conduit 32 to a condenser. The plates of the dismantled contactor shown in Fig. 6 have two inlet ports and two outlet ports within the area enclosed by the gasket associated with the plate; and the dispersion flows up through the passageways between the plates from inlet conduits 82a and 82b, formed by the successively positioned inlet ports; the dispersion then leaves the passageways through conduits 84c and 84d. Other types of plate may be used, e.g. each plate may have one inlet port and two outlet ports. The contactor may comprise more than one set of plates, and the arrangement of ports of one set may differ from that of another set. In examples, styrene monomer is stripped from carboxylated styrene-butadiene latex with steam in a dual-dual port flow plate contactor, without deposition of latex material on the plate surfaces. The contactor comprises five sets of nine plates.

Filed: 1965-04-06
Abstract: 1,093,856. Photographic type-composing machines. INTERNATIONAL PHOTON CORPORATION. April 6, 1965 [May 20, 1964], No. 14492/65. Heading B6W. A character carrier 2, Figs. 2 and 4, comprises apertures 54 over each of which is secured an opaque matrix 92 formed with rows of transparent characters (e.g. each row being in a different style) and reference marks 88. Two carriers 2, 3 (e.g. one for lower and one for upper case characters) in the form of endless bands are fed continuously through an exposure zone 80-81, Fig. 1. At any instant, several characters are present in the zone, and a latent image thereof is formed on a stationary film 22. The particular carrier and row can be selected by means of a shutter 166, Figs. 10 and 11, and mirror and prism system, Fig. 10. Characters to be projected are selected by a computer, Fig. 9, reading a coded tape. By means including a photo-cell 30 and the marks 88, the position of the selected character in the zone is ascertained, and when its latent image coincides with the position on the film where it should be projected, a light source 24 is instantaneously energized. At the same time, means is provided whereby only the selected character is projected, which may comprise a shutter band 4, Fig. 1, having an aperture 56 located by a stepping motor 14 acting against a clock spring under control of the computer, a rotating mirror 190, Fig. 12, to direct the light from a source 186 to the desired zone 196, or a flexible light tube 200, Figs. 13 and 14, controlled by the stepping motor 14. The point size is controlled by rotating a member 226, Fig. 15, to bring one only of the lenses (220, 222, 224) into operative position. Normally, characters pass through the zone 80-81 in alphabetical order, several alphabets passing through during each complete revolution of the carrier. When two characters are selected in succession, the second of which occurs later in the alphabet, they can thus be exposed during one alphabetical sweep. Alternatively, the characters can be arranged according to expected frequency of use, the more frequently used ones passing more often through the zone. The carrier may be a drum, field-flattening lenses being used to prevent distortion due to arcuate movement of the characters through the zone.
