Abstract: 271,571. Columbia Graphophone Co., Ltd., and Forse, W. T. Feb. 26, 1926. Sound magnifying and directing appliances. - The sound passage of a gramophone &c. horn is so designed that the sectional area at a point two-thirds of the total length from the inlet end is g i v e n by the formula a #l (c - a<2>) / x where a is x the inlet diameter in inches, l is the total length in inches, c is the outlet area in square inches, x = #p, and p is a frequency lying between the highest fundamental note in the musical side and that of the highest audible sound. The inlet and outlet dimensions are chosen as convenient, whilst the length may be determined from the relation l = # #v/f where v is the velocity of sound in inches per second and f is a frequency lying between the lowest essential speech frequency and the lowest audible frequency. If the sectional area as given by the above formula is not sufficient to satisfy the relation with regard to total amplifying area set out in Specification 215,976, the main passage may be divided into two or more branches each satisfying the above sectionalarea relation whilst the total amplifying area of all of the branches satisfies the relation in the prior Specification. The Figure shows such a divided horn having a single inlet l which then divides into two oppositely-directed passages m<1>, m<2> running back towards the inlet end, the passages then being bent back upon themselves so as to terminate in flared ends i remote from the inlet. In a modification, the inlet l runs vertically downwards whilst the dividing passages are first directed upwards towards the inlet and then bent horizontally to flare out and join each other. The horn may be of lead-covered iron sheet, or of zinc, and may be covered with a celluloid paint or varnish.

Patent GB-635493-A (GB)
Title: Process for producing hydrogen
IPC: C01B3/40
Filed: 1947-03-03
Abstract: Hydrogen is produced by passing a preheated mixture containing one part of a gaseous paraffinic hydrocarbon, e.g. methane, to 20 to 50 parts of steam at 480-705 DEG  C. and 13.5-34 atmospheres pressure, through an insulated catalytic converter, the preheated mixture being supplied with sufficient heat to furnish the endothermic heat of reaction and to maintain the converter at 480-705 DEG  C.  Effluent steam is preferably condensed by passing it through a waste heat boiler wherein it generates a source of low-pressure steam as a by-product.  Suitable catalysts are nickel and cobalt, with or without promoters.  A nickel-nickel oxide catalyst is prepared by adding a hot saturated sodium carbonate solution to a nickel sulphate solution containing diatomaceous earth in suspension, removing the precipitated nickel carbonate-diatomaceous earth mixture, washing, drying and reducing with hydrogen at 538 DEG  C.

Title: Conditioning crimped, continuous filament tow
IPC: D06B3/04
Filed: 1963-02-15
Abstract: 1,006,871. Rollers in spinning etc. machines; treating fibres. EASTMAN KODAK CO. Feb. 15, 1963 [Feb. 20,1962], No. 6158/63. Headings DID and D1F. In conditioning crimped, continuous, filamentary tow (prepatory to its manufacture into cigarette filter-tips) by the pressure jet method of opening, the tow is fed under tension to the jet from a pair of driven rollers which pull it under tension through the nip of a pair of punch rollers to which it is fed from a tow supply. The conditioned tow is stated to be uniform both cross-sectionally and longitudinally. As shown, Fig. 2, a tow (with twist removed by a device 3) is withdrawn from a bale and passes over a cylindrical guide 1, through punch rollers in an assembly 21, through driven rollers 4 which may have three to ten times larger diameter than the punch rollers, it receives a treating agent e.g. liquid plasticiser, within an applicator 5, then passes through a jet 6 from which it is withdrawn by rollers 7 and may proceed to a filter-plug former (not shown). The rollers 4 pull the tow under tension through punch rolls and the jet 6 pulls the tow from rollers 4 under sufficient tension to prevent "blooming" thereof as it leaves these rollers, and within the jet the filaments are forced apart by the air under pressure. The ratio of weight to unit length of the tow fed to the jet is controlled by adjusting the speed of rollers 4 and the pressure on the punch rollers 36, 37, Fig. 3. The jet 6 is supplied with air through an automatic valve 18 and conduit 25 connected in the same air line 43, Fig. 3, as supplies air through a pressure reducer 45 to the bellows, in housings 39 and 42, by which the ends of the shaft of roller 37 are loaded: thus the pressure on rolls 36, 37, is automatically relieved if the air supply to jet 6 ceases. The bellows may be replaced by mechanical and/or electrical means (not shown). A motor 22 synchronously operates all the mechanisms of the apparatus, including pumps supplying the applicator 5, through chain or belt and sprocket drives, including a variable transmission device 23 for rollers 7. Specification 986,391 is referred to.
