Title: Process for the recovery of a solvent from a mixture of the solvent with one or more hydrocarbons
IPC: B01D3/06
Filed: 1958-06-17
Abstract: In the recovery of solvents, such as furfural, phenol, nitrobenzene, and b ,b -dichloroethyl ether, from mixtures thereof with one or more hydrocarbons of higher boiling-point than the solvent by flash vaporization firstly at about atmospheric pressure, secondly, after heating, at superatmospheric pressure and thirdly at subatmospheric pressure, solvent being recovered overhead from each stage, a part of the solvent is introduced as reflux to at least one stage and a liquid side stream is withdrawn from the last stage, at a point above the feed inlet, and passed to the lowest point of the first stage.  A side-stream may also be removed from the second stage and passed to the first zone.  The side stream is obtained by having several rectifying trays above the feed inlet, the lowest being designed to accumulate liquid. Pressures may be in the first stage 0.9-1.4 atmospheres absolute, in the second 2-4 atmospheres and the third 0.05-0.4 atmospheres.  Any solvent remaining in the hydrocarbon may be removed by steam stripping.  The process may be applied to the raffinate or extract fraction from a solvent extraction process.

Title: Flight control systems
IPC: G05D1/00
Filed: 1962-05-21
Abstract: 955,911. Automatic steering control. SPERRY RAND CORPORATION. May 21, 1962 [May 22, 1961], No. 19423/62. Heading G3R. In an automatic flight control system a signal representing the difference between a selected heading and the actual heading of an aircraft is applied to first means which, alone, cause control about the yaw axis if the signal is below a predetermined value, and to second means which cause control about the roll axis when the signal, is above the predetermined value. As shown, when an aircraft deviates from a heading determined by the setting of a manually adjustable inductive device 12,A.C. signals corresponding in magnitude and phase sense to the deviation are produced at terminals AB from a gyro-magnetic compass 10. If these signals are small they pass through a limiting circuit 18 to restore the desired heading automatically by control of the rudder. The deviation signals are also rectified at 20 and serve to bias rectifiers 28, 30 in a forward direction so that if the deviation exceeds a predetermined value the input to the rudder control system is gradually reduced and finally short-circuited. The deviation signals are then sufficiently large and render e.g. a double Zener diode 16 conductive to restore the desired heading by control of the ailerons. If desired, by changing over a switch 19, rectifier 20 may alternatively be energized from the bank pick-off of a gyro-vertical 38 so that if the deviation is sufficient to introduce aileron control, the resulting bank of the craft is effective through rectifier 20 to remove rudder control. In a modification the deviation signals control the energization of an electromagnetic relay so that below a predetermined magnitude of deviation the relay is deenergized to render rudder control effective through normally closed relay contacts while above the predetermined magnitude the relay is energized to render the aileron control effective instead through normally open contacts.

Abstract: 586,773. Moulding chocolate. BAKER & CO., Inc., W. Oct. 10, 1944, No. 19489. Convention date, Nov. 12, 1943. [Class 87 (ii)] [Also in Group VI] Layers of different kinds of chocolate, e.g., light milk chocolate mounds 19 on a dark chocolate base 18, are integrally united by depositing the first tempered layer in a mould and partially cooling until 10-40 per cent. only of its fat content is crystallised which forms a substantially non-fluid mass able to support another tempered layer deposited on the top of it. By this method the uncrystallized fats of the two layers unite to form a continuous liquid phase. One of the fayers may include a proportion of nuts between two layers of chocolate. Fig. 1 shows an apparatus for making a two layer product in which a conveyer 10 carries a mould through a mould conditioner 11 to a deposit point 12 to receive a layer of tempered chocolate. The mould then proceeds and is shaken at 13 to release air bubbles, cooled at 14, e.g., by air streams, receives a second layer at 15, is shaken at 16 and then finally cooled at 17 the block being knocked out on its way back to the conditioner 11. In making, e.g., a two layer bar of 1¢ ozs. weight, the mould is conditioned to a temperature of 80‹-84‹F., the light chocolate is tempered to 83‹ to 86‹F. and passes through a short cooling tunnel for 45-60 seconds in air at 40‹F. The chocolate has now dropped to about 75‹F. A dark layer tempered to 85‹-88‹F. is then deposited and after shaking passes through a long cooling tunnel for 20 minutes at air temperature of 40‹F.

Abstract: 1,007,115. Frequency modulation. HONEYWELL CONTROLS Ltd. May 7, 1964 [May 17, 1963], No. 19628/63. Heading H3R. A generator circuit which supplies a train of output pulses having a frequency representative of the magnitude of an applied D.C. signal comprises a voltage controlled saw-tooth oscillator 15 to which the input signal is applied via amplifier 16, a mono-stable circuit 17 which is triggered by the oscillator output pulses after differentiation, differentiating circuits 22 which receive on lines 21 both positive and negative outputs of the mono-stable circuit and supply on lines 23 and 24 respectively, short positive going pulses spaced 4À5 m. sees. apart corresponding to the leading and trailing edges of the mono-stable circuit output pulses, a second sawtooth oscillator 26 operating at a fixed frequency which develops a short duration positive pulse train at the output of inverter 28 and a frequency difference circuit supplied with the three trains of positive pulses which provides an output pulse train at a frequency equal to the difference between the frequencies of the oscillators. The oscillator 15 comprises a transistor 4 operating in the common base mode having its base connected to a fixed potential, its emitter connected to the applied D.C. input terminal and its collector connected via a Shockley diode 5 to a - 48 V supply and via a capacitor 1 and resistor 2 to ground. Assume the Shockley diode is in its low impedance state, capacitor 1 rapidly discharges to - 48 V with consequent drop in voltage across the diode which then assumes its high impedance state. The capacitor is charged via the transistor circuit at a rate proportional to the value of the voltage applied to its emitter and when charged to a value which produces a voltage drop of 20 V across the diode, the diode switches to its low impedance state to discharge the capacitor. The process repeats at a frequency determined by the capacitor charge rate which is controlled by the D.C. voltage applied to the emitter. The difference circuit, Fig. 3 (not shown) acts to pass the positive pulse on line 24 to the output terminal except when the pulse on line 23 is preceded by a pulse from the fixed frequency oscillator 26. Specification 1,007,114 is referred to.
