Title: Method and apparatus for the production of beverages containing carbon-dioxide
IPC: B01F13/10
Filed: 1933-05-02
Abstract: 404,189. Aerating liquids. DIETZEL, P., 95, Geisselstrasse, Ehrenfeld, Cologne, and RUBEN, E., 9, Boltensternstrasse, Dusseldorf, both in Germany. May 2, 1933, No. 12789. [Class 14 (i).] Aerated beverages are produced by dissolving solid carbon dioxide in a liquid in a pressure resistant container 1, the solid carbon dioxide being first introduced into a receiver 28 located underneath the inlet 5 of the container 1, and only brought into contact with the liquid by tilting the receiver or otherwise discharging the contents thereof, when the inlet 5 has been sealed hermetically, for example, by means of a cover 8. The pressure container 1 is divided by a partition 2 into an upper generating chamber 3 and a storage chamber 4 connected thereto by means of a union 12 containing a shutoff valve normally kept closed. Aerated liquid produced in the chamber 3 can be allowed to flow into the storage space 4 by operating a handwheel 13 controlling this valve. The upper part of the chamber 3 is also connected with the chamber 4 by way of a pipe 15 leading through a diaphragm reducing valve 16 to a pipe 24. The valve 16 is suitably loaded, so that when a certain pressure is exceeded in the chamber 3, carbon dioxide passes therethrough into the chamber 4, the pressure in the latter being limited by means of a blow-off safety valve 25, which may be similar to the valve 16, and allows excess gas to escape through a branch pipe 26. The discharge of the solid carbon dioxide may be effected by rotating with the aid of a lever 30 the spindle 27 to which the receiver 28 is fixed, an alternative arrangement being also described whereby the bottom of the receiver 28 is hinged, and can be kept closed, or lowered, by a similar spindle arrangement. The partial or complete equalisation of pressures in the chambers 3 and 4 by means of pipes 15 and 24 and valve 16, before aerated liquid is transferred from the upper to the lower chamber, prevents release of dissolved gas taking place in the latter. When the aerated liquid is to be served directly, the storage chamber 4 is preferably connected with a serving device 36, which contains a pressure relieving space 37 capable of holding a volume of liquid equal to that of the vessel to be filled. By moving a hand lever 53 backwards and then forwards, valves 39 and 49 are alternately operated, so that by the first operation liquid is admitted to the space 37 by way of a pipe 43, and by the second operation excess carbon dioxide gas is released through a pipe 56 to the atmosphere. The pressure of the aerated liquid coming from the pipe 43 during the first operation closes a tapping valve 44, so that the space 37 is shut off from the outside. When the pressure of gas in the space 37 has been relieved by means of the valve 49, the valve 44 automatically opens, and allows the aerated liquid to be delivered through a passage 48.

Figs. 1 and 3 show a tuning scale unit comprising a braced sheet metal structure, in the front member 13 of which is a long aperture 24 and on each side of this aperture are disposed the wavelength scales 64 ... 68 one for each waveband, each being edge-lighted by lamps such as 81, 82, selected by operation of the waveband switch. The tuning indicator 51 is of the single or dual light-band type and projects through an aperture in a plate 53, mounted on a bracket 32, which slides vertically up and down a channel section rail 30. The cursor 63 is also carried by the bracket.32, which is controlled by chain drive from the tuning shaft 91 over pulleys 35, 36, 38, 39, 93, the chain ends being anchored at 95, 96 to the bracket 32. The aperture 24 is closed by a band of black material secured to member 53 and moving therewith, each end being wound on to spring rollers 59, 60 which keep the band taut. If the indicator 51 is of the single band type and the tuning scales are disposed on each side aperture 24, as shown, the indicator may be rotated by the waveband switch so that the light band always co-operates with the scale in use. The light band may itself constitute the tuning scale pointer or cursor. Specifications 438,010, [Group XXXVI], 442,158, and 474,923, [Group XXXVI], are referred to.
