Average particle size is defined as that in relation to which 50 by wt per cent of the particles are larger and 50% are smaller. The sucrose solution may be pre-heated e.g. to a temperature of 50 to 100C., and the temperature within the dryer is controlled e.g. at 50 to 130C. Recycled solids are reduced to the required size by grinding, or are deagglomerated by attrition or impact.

Title: Improvements in or relating to fluid-metering apparatus
IPC: G01F9/00
Filed: 1944-09-18
Abstract: 597,087. Fluid-pressure servomotor-control systems. PARRY, J. F. W. Sept. 18, 1944, No. 17821. [Class 135] [Also in Group XXVII] A fluid-metering device for giving a flow inversely proportional to a variable condition or factor is described in relation to the flow of fuel to an aircraft engine, the variable factor being the absolute ambient temperature. The flow may also be controlled in proportion to other additional variables such as the engine speed, and the induction pipe pressure less a constant proportion of the exhaust back-pressure. In the Figure a fuel pump 1, driven from the engine draws its supply by a conduit 2 from the fuel tank and delivers to a conduit 3 a flow proportional to the engine speed at a pressure P1. The flow then passes through an orifice 4 controlled by a valve 6, which is operated by pressure of a fluid on a capsule 7 from a conduit 9 in communication with a temperature bulb situated in the induction pipe. A drop of pressure across the orifice 4 to a value P2 is obtained and a further drop to a value P3 across another orifice 14, controlled by a valve 16 actuated by a device indicated at 17 which is responsive to the induction pipe pressure minus a constant proportion of the exhaust back-pressure. The pressure drops PI-P2 and P2-P3 across the two orifices act on differential diaphragms 18, 19 actuating a spill valve 10 to return fuel to the supply conduit 2 so that the flow past orifice 14 to the conduit 15 leading to the engine spraying nozzle is according to the law F = K PN/T where P is the pressure factor at the device 17, N is the engine-speed, and T is the absolute temperature in the induction pipe. For idling or slow-running a different relationship of the fuel supply is obtained by an adjustable loading spring 22 acting on the diaphragm 19, which is only effective with the small pressure drops under these conditions, to increase the flow. A momentary increased flow of fuel is also obtained from a pump connected to the throttle lever which delivers an additional amount of fuel through a conduit 25, which acts upon the diaphragm 19 to close the spill valve and also passes to the delivery conduit 15, whenever the throttle is moved to accelerate the engine. An additional orifice 23 controlled by a needle valve 24 may be provided as shown in parallel with the orifice 14, or it may be arranged in series, to enable an accurate adjustment of the fuel flow under idling conditions. This valve may be coupled to the throttle lever so as to be set to an appropriate position corresponding to the throttle position. The valve 16 may also be suitably shaped to give an increased flow at maximum power output of the engine, corresponding to the maximum induction pipe pressure.

An alternative embodiment (not described in detail), has the master recordings on separate tapes, with a plurality of drive-capstans and playback heads, one of a set of pinch-rollers being engaged to effect selection. The selection being copied is also played back to the customer by loud-speaker means.

Title: Processes for carrying out chemical reactions
IPC: C01C1/04
Filed: 1930-06-17
Abstract: Chemical reactions, particularly the synthesis of ammonia, are carried out with the aid of direct <PICT:0357534/III/1> current glow discharges, under such conditions that the space occupied by the cathode fall in potential is approximately equal to the space between the electrodes.  The discharge to be used is defined as self-sustaining in the presence of a strong space charge, in which heating of the cathode is not necessary to sustain the discharge. The process is preferably carried out using unequally curved electrodes, one of which is spaced from and surrounds the other, as shown in the Figure.  The more strongly curved electrode 5, in the form of a straight unheated platinum wire, is used as the negative electrode.  The gas mixture, e.g. nitrogen and hydrogen, is previously dried and led through the reaction chamber 1 at a pressure preferably below 15 cm. of mercury.  In an example, the gas mixture is passed through the reaction chamber at the rate of 40 litres per hour, the voltages used being varied from 320-450 volts and the gas pressure from 30-70 mm. of mercury.  A constant discharge current of 40 milliamperes is obtained.  The process can also be used for the manufacture of acetylene from methane or a methane-containing hydrocarbon mixture, with or without the addition of hydrogen. The reaction product contains polymers of acetylene, such as diacetylene.

Title: Recovery of catalyst residue from the synthesis of acetic acid
IPC: B01J31/40
Filed: 1961-05-23
Abstract: In a process for the synthesis of acetic acid from methanol and carbon monoxide in the presence of a nickel and iodine containing catalyst, the catalyst residue is recovered from the cinder product by stripping it with a gas containing at least 50% by volume of carbon monoxide and distilling under reduced pressure. The stripping gas which may be entirely carbon monoxide or also contain methane, carbon dioxide, nitrogen and hydrogen removes the nickel carbonyl and methyl iodide, and the crude product is then distilled under reduced pressure to leave non-volatile catalyst components e.g. nickel iodide or acetate as tails which may be recycled.  The volatile catalysts may be washed from the stripping gas with methanol and the washed gases reused for the stripping. The stripping stages may be at atmospheric or higher pressures and the product comprising acetic acid, methyl acetate and alcohol, water, nickel iodide and acetate is distilled in two columns in series, in the first of which methyl acetate is distilled as heads between 55 and 60 DEG C., and in the second acetic acid and water are obtained in the head, and a solution or suspension of nickel acetate and iodide in acetic acid is discharged. The distilled acid may also be treated with activated carbon.
