Title: Improvements in and relating to the reproduction of sound
IPC: C22C21/02
Filed: 1925-05-11
Abstract: 256,677. O'Donnell, P. S. May 11, 1925. Loud-speakers; magnetic instruments.-Relates to sound-reproducing apparatus such as telephonic loud-speakers. According to the invention, tuned gongs are provided in association with the soundemitting diaphragm and are adapted to vibrate sympathetically therewith. In the loud speaker shown, which embodies a conical diaphragm 3 and other features described in Specifications 261,154 and 259,103, a number of tuned gongs 13 are supported by a ring 14 fixed near the open end of the cylindrical casing of the instrument. The gongs are separated from each other by radial baffle plates 15, also mounted on the ring 14, the plates beng tapered as shown towards their inner ends which are fixed to a ring 15a. A glass disc 10 supports the electromagnetic mechanism, and from this disc extend four wooden rods 18 which are bolted to the ring 14. By this means, the gongs are maintained in a slightly tremulous state, which is said to render them more readily susceptible of sympathetic response. Means for transmitting vibrations to the diaphragm 3 through two diamonds in contact, and auxiliary diaphragms 16, are provided as described in the aforesaid Specifications. According to the second Provisional Specification a sound-amplifying device for a gramophone or loud speaker comprises a box or casing partially closed by glass, mica, &c. and containing a number of tuned gongs. The diaphragm of the gramophone sound box or equivalent primary vibrating member sets up sym. pathetic vibrations in the amplifying device, either by direct mechanical connection or by transmission through the air. The third Provisional Specification describes a loud-speaker in which the casing, provided with tuned gongs as in the constructions described above, is a rectangular box having a slotted front. Four thin wooden panels are arranged pyramidally at the back of the box to form a small space enclosing the electromagnet. Adjustment of the contact between two diamonds through which vibrations are transmitted from the magnetic armature to the diaphragm is effected by means of a knob on the end of a rod which carries the main auxiliary diaphragms, the rod extending through the front of the box. The sensitivity of the gongs may be increased by keeping them in permanent slight vibration, by means such as an electric buzzer.

Title: Method of working up aqueous liquors containing ammonia
IPC: C01C1/10
Filed: 1955-04-29
Abstract: 768,830. Distilling ammoniacal liquors. METALLGES AKT.-GES. April 29, 1955 [May 3, 1954], No. 12543/55. Addition to 733,796. Class 32 [Also in Group XII] In a method of extracting ammonia from aqueous liquors containing phenols, ammonia, carbon dioxide, hydrogen sulphide and possibly other organic or inorganic substances, as described in the parent Specification, the heat of the ammoniacal vapours produced when the ammonia is driven off from the liquors is used before treating the vapours with acid for the purpose of stripping the ammonia from the liquors. As shown, ammoniacal liquor, which has been dephenolized by extraction with oxygencontaining organic solvents which are insoluble or only slightly soluble in water and which have a lower boiling point than the phenols, is passed through pipe 1, heat exchanger 2 and pipe 3 into plant 4 in which the solvent residue is stripped from the liquor. The liquor passes through pipe 6, heat exchanger 7 and pipe 8 to stripper 9 the mixture of water vapour and ammonia passing therefrom through pipe 10 compressor 11 and pipe 12 to an evaporator 13. Here the vapour mixture gives up heat to produce water vapour whilst a part of the vapour mixture condenses. The remaning vapour passes through pipe 14 to a saturator 15 wherein the ammonia is reacted with sulphuric acid to form ammonium sulphate which is removed at 16. Gases and vapours, such as carbon dioxide and hydrogen sulphite, are returned through pipe 51 to plant 4 leaving the latter at 5. The condensate formed in evaporator 13 flows through pipe 17, container 18, pump 19 and pipe 20 as reflux to column 9. From the sump of column 9 water freed from ammonia passes through pipe 21 to evaporator 13, the water vapour produced therein passing through pipe 22 into column 9. Additional steam may be supplied at 23. Another part of the ammonia-free water passes from column 9 to the heat exchangers 2 and 7. In a modification vapour mixture from the stripper passes directly to an evaporator the steam generated therein flowing to the stripper through a compressor which may be operated by steam which is also supplied to the stripper. In modifications a turbo-compressor, piston compressor, or blower are used. Fresh water, cooling water or condensate may be passed to the evaporator instead of using water from the sump of the stripper.

Title: Improvements in or relating to mass flow control systems
Inventor: GRIEVE JOHN
IPC: B64D13/04
Filed: 1953-05-06
Abstract: 760,111. Automatic air-flow control systems. NORMALAIR, Ltd. May 6, 1954 [May 6, 1953], No. 12581/53. Class 38 (4). In a system for maintaining constant mass air-flow through a duct to the pressurized cabin of an aircraft in which the pressure difference in a venturi-type head measuring airflow in the duct controls electrical contacts energizing an electrically operated flow valve in the duct, the venturi is automatically throttled in response to pressure in the duct. In Fig. 1, air supplied to conduits 10 from port and starboard aircraft engines, respectively, passes through refrigerators s and non-return valves t to a common conduit 13 leading to the aircraft cabin. In each conduit 10 a venturi tube 1 measuring air-flow is arranged to maintain constant mass air-flow by electrically controlling a valve 2. In order to increase airflow automatically whenever a refrigerator s is put into operation, the increase in back pressure resulting from putting the refrigerator into operation influences a piston 3 through a conduit 14 to move a spring-loaded rod 4 into the throat of venturi tube 1. In the event of failure of one of the aircraft engines, the resulting drop of pressure in the corresponding conduit 10 allows an associated spring-loaded piston 6 to be moved so that the pressure in the other conduit 10 is effective through an associated non-return valve 9 and conduit 8 to influence pistons 16 moving rod 4 into the venturi throat so as to increase air flow from the engine still functioning. Specifications 655,328 and 656,763 are referred to.
