Title: Improved method of treating cocoa powder
IPC: A23G1/04
Filed: 1957-02-12
Abstract: 830,946. Cocoa manufacture. STERK, J. G. Feb. 5, 1958 [Feb. 12, 1957], No. 4748/57. Class 129. Cocoa powder is heated in a closed space from which oxygen is substantially excluded to a temperature between 170‹ C. and 220‹ C. until it attains the required colour and is then cooled in the same or a different space to a temperature at which none of its constituents can be oxidized before exposing to the normal atmosphere. Cocoa powder ml is supplied from a hopper 28 through a conveyer 29 to the top 31 of heating chamber 1 which has a stirrer 2, is airtight and is surrounded by a heating jacket 6 with electric resistances 7, 8 connected to heat regulator 11. The regulator 11 contains switches controlled by temperature-sensitive devices 12, 13 arranged respectively in chamber 1 and jacket 6 and through lines 16, 17 to an electricity supply. Jacket 6 is supplied with mineral oil from reservoir 18 through tube 19 and regulating valve 20. Alternatively, it may contain air to be heated by infra-red radiation. The cocoa powder is heated in an atmosphere of carbon dioxide. After heating, the powder is discharged through passage 34 and valve 35 to the bottom portion 36 of another elevator cylinder 37 through which it is fed to cooling chamber 66. Valve 35 is surrounded by a box 40 having a perforated partition wall 41 between it and a duct 42 connecting valve 35 with the bottom of the elevator. Portion 36 is supplied with gaseous carbon dioxide. Before valve 34 is opened, box 40 is filled with solid carbon dioxide so that gaseous carbon dioxide prevents air and oxygen from coming into contact with the hot cocoa powder. The powder is then cooled further in chamber 66 which has a stirrer 44 and is surrounded by a cooling jacket 47 through which water is circulated. An atmosphere of carbon dioxide is maintained in elevator 37 and chamber 66. A temperaturesensitive element 12a co-operating with an indicating or controlling device 12b supervises the cooling in chamber 66. The cooled cocoa powder m3 is discharged to a vibrating sieve 62 from which the fine material falls into a container 63 which may be part of a weighing machine. Nitrogen may be used instead of carbon dioxide.

Patent GB-1077336-A (GB)
Title: Solid foamed sulphur and process for the manufacture thereof
IPC: C01B17/02
Filed: 1966-02-04
Abstract: Porous sulphur is prepared by heating the sulphur to about 150 DEG C., adding in either order a stabilizing agent and a viscosity increaser, forming bubbles in the molten mixture and then cooling below its melting point.  A cellular structure free from voids is obtained.  The viscosity increaser is selected from phosphorus, arsenic, selenium, phosphorus sulphides, styrene monomer, ethylene disulphide, "Thiokol" (Registered Trade Mark) and polysulphide rubbers and liquids.  It preferably contains P2S5.  The stabilizing agent is a finely-divided inert material with plate-shaped particles. It is selected from, kaolin, china clay, ground mica, aluminium pigment, talcs and sands with plate-shaped particles, "Permanent Yellow organic pigment" and "Hansa Yellow G" pigment.  "Mistron Vapour" (Registered Trade Mark) is preferably.  The bubbles in the molten sulphur are formed by mechanical mixing with a gas, adding a blowing agent, or mixing a liquid with the molten sulphur under such a pressure, that when the pressure is removed the liquid vaporizes.

Title: Improvements in or relating to modulator circuits
IPC: H03C1/54
Filed: 1950-02-28
Abstract: 669,223. Modulating systems. WESTERN ELECTRIC CO., Inc. Feb. 28, 1950 [March 5, 1949], No. 5070/50. Class40(v). Capacitative unbalance in a balanced modulator comprising a pair of valves 18, 19 fed with a modulating signal from transformer 3 and with cathode modulation by a carrier source 14, 25, producing in an output circuit 12 normally a suppressed carrier wave, is neutralized by a capacitor 15 connected between the cathode and anode of one valve (19), to ensure the anode output of this valve circuit being the more unbalanced, and by a tapped potentiometer 16 and capacitor 17 between cathode and anode of the other valve, adjusted to balance out any phase quadrature component of the carrier in the output circuit. The common cathode load resistor 20 and the potentiometer 16 are both fed from the carrier source 14 through a buffer amplifier 25. The in-phase component of the unbalanced carrier output is at the same time cancelled out by relatively adjusting the screenpotentials of the valves 18, 19, and therefore the mutual conductances, by a potentiometer 22. Any amplitude and phase of carrier frequency in the output circuit may therefore be cancelled out. The anode circuit of the carrier amplifier 25 includes an H.T. dropping resistor 29. By cathode modulation any variation of carrier voltage during action of the modulator is minimized. In a video modulator, Fig. 3 (not shown), the signal is applied to the valves 18, 19 through two pairs of D.C. coupled valves the latter being cathode followers, and a rectifier 59 is connected between the grids of the valves 18, 19 so that the D.C. component of the signal is retained. Specifications 130,219, 244,190, [both in Class 40 (v)], 556,430 and 584,046 are referred to.
