Title: Improvements in emulsifying apparatus
IPC: B01F25/74
Filed: 1944-08-10
Abstract: Emulsifying apparatus, comprising mixing, heating, emulsifying and cooling tube units, together with means for conveying the material in sequence from one to the other, is mounted on a portable frame structure.  The apparatus is suitable for producing oil in water emulsions, particularly synthetic milk, cream, ice cream or other milk products.  Materials in a tank 5, agitated by a stirrer 8 and heated by an electric <PICT:0583082/III/1> heater 7, flow through a hand-operated outlet 29 and a float 32 controlled feed valve to a feed cup 26, whence they are drawn into a rotating bowl 13 of an emulsifier 12 of the kind described in Specification 575,466, [Group II].  The resulting emulsion passes through a spout 34 to a trough 35 which distributes it over cooling tubes 36 down the outside of which it flows to the receiver 43.  A housing 1, fitted with castors and feet, carries the above apparatus and is also provided with a heavily insulated storage tank 37 for refrigerant 38, which is circulated to the tubes 36 by a pump, and with a small compressor which circulates a cooling fluid through the coils 45 which cool the refrigerant. The stirrer, emulsifier, pump and compressor may be operated independently, e.g., by electric motors and belt drives.ALSO:Emulsifying apparatus (see Group III), comprising mixing, heating, emulsifying and cooling tube units, together with means for conveying the material in sequence from one to the other, all mounted on a portable frame structure, is used for producing oil in water emulsions, particularly synthetic milk, cream, ice cream or other milk products.  The production of milk or cream from a mixture of skimmed milk powder, fresh unsalted butter and water is described.

Abstract: 515,070. Valve amplifying circuits. BARRETT, A. E., MAYO, C. G. and DAVIES, H. May 23, 1938, No. 15360. [Class 40 (v)] A tone control device, applicable directly to an audio amplifier, or to vary the band width of a modulate carrier wave, comprises a filter 6 passing a range of frequencies in, and representative of, the upper portion of the audio band including unwanted high frequency disturbance, and a rectifier arranged so as to derive a voltage dependent upon the lowest level reached by the output averaged over a pre-determined time interval. Fig. 1 shows an arrangement in which no current flows in rectifier 14 until the smoothed output of rectifier 8 falls below a pre-determined value, which may be varied by connecting resistance 13 to a tapping on resistance 9. Current flow in rectifier 14 charges reservoir condenser 18 the time constant of the discharge circuit being determined by resistance 15, so that a voltage in accordance with the lowest signal voltage is obtained and is used to control the automatic tone control device 12.
