Abstract: 482,871. Bottle - washing machines. SIMONSSON, W. Oct. 26, 1937, No. 29180. Convention date, Feb. 19. [Class 138 (i)] In a machine of the kind in which bottles supported in holders 2 on a chain 1 are carried through a plurality of washing stations, each station having upper and lower spraying nozzles 26 and a separate pump 18 for supplying liquid thereto, the nozzles of each section are divided into two or more groups each of which is alternately opened and closed during the operation of the machine. At each station, the pump 18 supplies liquid from a tank 17, by way of a pipe 19 with a pressure-equalizing chamber 27, to two pipes 20, 21 provided with valves 22, 23. The pipes 20, 21 are connected to pipes 24, 25 carrying the groups of nozzles 26. The valves 22, 23 are alternately opened and closed by levers 16 actuated from the main shaft 10 through links 14, 13 and gearing 9, 11. The shaft 10 drives the chain 1 through a pawl and ratchet 6, 5. The levers 16 are rocked four times for each step of the chain. Bars 30 in the central washing section, where the highest washing pressure is employed, prevent the bottles from being forced from the holders. In modifications, the valves 22, 23 are controlled by cams, which may be arranged to actuate valves for three groups of nozzles, or to close both valves during the forward movement of the bottles.

Abstract: 473,806. Foghorns. EKMAN, O. I. H. Oct. 29, 1936, No. 29427. Convention date, Oct. 29, 1935. [Class 13] [Also in Group XXXIX] In a foghorn operated by compressed fluid, a plurality of diaphragms, vibrated either in groups or simultaneously, form parts of the wall of a receptacle for the fluid and are alternately subjected to the pressure prevailing in the receptacle and relieved from the pressure by a rotatable slide valve located adjacent the wall. As shown, the valve comprises a central portion 4 mounted on a rotatable shaft 5 and an annular portion formed with apertures 6 alternating with radial grooves 7 which co-operate with radial passages 8 in the wall of the receptacle 1 to relieve the pressure to which the diaphragms 9 have been subjected. The diaphragms 9 which are supported on projections 18, 19 carried by a fixed central portion 10 and a flanged portion 12 of the casing 2, are formed with bent-up outer ends clamped between members 13, 14, Fig. 6, which are adjustably secured to the flange 12 by bolts 16. The central portion 10 is connected to the portion 12 by wedge-shaped beams 20 which are located between successive diaphragms 9 and form sound-projection channels communicating with the space between walls 21, 22 terminating in a horn which is preferably rotatable. In one modification, Figs. 7, 8 (not shown), the width of the apertures 6 and grooves 7 is substantially less than that of the diaphragms 9 with the object of providing an arrangement to produce a sound of increased frequency, and in a further modification, Figs. 10, 11 (not shown), the slide valve has four equally spaced apertures 6 which co-operate with twenty diaphragms 9, the pressure on any diaphragm between its successive actuations being relieved by the provision of a small hole under the edge of the diaphragm. In a further modification, Fig. 9 (not shown), in which the widths of the diaphragms 9 and apertures 6 are approximately equal, the supporting members 20 are provided with projections which limit the application of the pressure to the central portion of each diaphragm.

The aqueous absorbent may be water, sodium phosphate solution, sodium citrate solution or their mixtures. The process may be cyclic. A modification of the above process in which the SO 2 -rich aqueous absorbent is contacted with a gas mixture containing H 2 S and one or more inert gases comprises providing H 2 S in an amount less than that required stoichiometrically to regenerate aqueous absorbent, separating the gas mixture depleted in H 2 S content from partially-regenerated absorbent which is contacted with a second gas mixture containing H 2 S in a stoichiometric excess of that required to regenerate aqueous absorbent.
Patent GB-294919-A (GB)
Abstract: 294,919. Lipman, C. L. March 31, 1927. Phase, changing.-In alternating-current single-phase apparatus of the moving-coil or moving-iron types, the moving member is acted on by one or more rotating fields due to magnetic fluxes relatively displaced in time and space produced from main and auxiliary windings on the core of an electromagnet energized by single-phase current's. Figs. 32 and 33 show a modification in which the coils P, S, Q<1>, Q<2> are placed inside the moving coil J. The outer laminated core B<3> of the field electromagnet forms a closed magnetic circuit. When used as a phase meter, the moving coil receives current from an outside source through slip-rings k<1>. The coil J may be considered as a source of induced current supplying an external load, the magnitude and phase of the current depending on the constants of the circuit, enabling the apparatus to be adapted as a singlephase phase-shifting transformer. An additional coil J<1> may be provided at 90‹ to the coil J, to form a single-phase to two-phase transformer. Similarly, three coils at 120‹ may be employed for transforming from single to three phase.

Specification 456,536, is referred to.ALSO:Packing-materials for use in apparatus for the manufacture and storage of fluorine are made by treating fibrous materials impregnated with one or more oils or waxes with fluorine under such mild conditions that the reaction mixture does not take fire. The fluorine may be diluted with an indifferent gas such as air, nitrogen or carbon dioxide, or the reaction may be carried out at reduced pressure or at a low temperature.  The substances treated may be asbestos, pasteboard, vulcanized fibre or pressboard or viscose or acetyl or benzyl cellulose in fibrous form impregnated with beeswax, artificial wax, chlorinated hydrocarbons, linseed oil or wood oil. In an example, pasteboard impregnated with beeswax is used for packing and insulating the anode of a cell for the electrolytic production of fluorine.  The fluorine evolved is diluted in the proportion 1 to 10 by introducing nitrogen or oxygen.  The dilution is afterwards reduced until 100 per cent fluorine is present. Packing-material may be treated before assembly.  Specification 456,536 is referred to.
