Title: Improvements in or relating to the recovery of glycerol and other high boiling substances from fermentation liquors
Inventor: LUCKHURST KENNETH JOHN CHARLES
IPC: C12P7/20
Filed: 1951-12-03
Abstract: High boiling components such as glycerol and 2 : 3 butandiol are volatilized from fermentation liquors by feeding the concentrated liquor into contact with a continuously renewed bed of granular solid material, e.g. sand, maintained in a fluidized condition by passing superheated steam through the bed.  The vapours leaving the fluidized bed may be washed with water, whereby there is obtained an aqueous solution of the high boiling components, which may then be recovered by distillation.  Steam withdrawn from the water-washing zone may be compressed, re-superheated, and recycled to the fluidized bed.  The spent granular material, <PICT:0717939/III/1> withdrawn from the fluidized bed, is transferred to another fluidized bed wherein the carbonaceous residue, deposited on the material, is burned off with air or oxygen; the re-vivified material is then returned to the main fluidized bed.  In the Figure, air is introduced through pipe 1, and carries sand from pipe 2 to the separating vessel 3, where the air leaves by pipe 4. Concentrated fermentation liquor is introduced through pipe 5. The granular mixture of sand and liquor passes through pipe 7 into vessel 9 where it is maintained as a fluidized bed 8 by passing superheated steam from pipe 10 through perforated base 11.  The spent mixture, after removal of glycerol, passes over weir 12 and through pipe 13 into vessel 15.  The vapours from vessel 9 are introduced into tower 17, where they are washed by a stream of water entering the top of the tower from pipe 18.  Aqueous glycerol is taken off from the base of the tower by pipe 19, and is passed to a rectifying still.  Steam leaves the head of the tower through pipe 20; some of it is bled off through pipe 22 and the remainder is passed to compressor 21.  The compressed steam is superheated in heat exchanger 24, and is then recycled to vessel 9 through pipe 10.  The fluidized bed 14 in vessel 15 is maintained in a fluidized state by passing air from pipe 25 through perforated base 26.  The combustion gases leave vessel 15 via cyclone 27, and are passed through pipe 29 to heat exchanger 24, and thence to a stack.  Ash is withdrawn through pipe 28.  The sand from bed 14 passes continuously over weir 31 into pipe 2, from which it is recycled to vessel 9.

Abstract: 914,653. Fluid-pressure brakes. CLAYTON DEWANDRE CO. Ltd. Dec. 7, 1959 [Sept. 5, 1958 (2)], Nos. 28609/58 and 28610/58. Class 103 (1). [Also in Group XXIX] In a tractor-trailer braking system of the kind in which the effort applied at the brake pedal is transmitted to a boosted or non- boosted hydraulic transmission to the tractor wheel brakes, the trailer wheel brakes being actuated by a fluid-pressure servomotor, the operation of which is controlled by a reaction valve R responsive to pressure generated in the hydraulic transmission, additional hand or pedal-operated means is provided for actuating the reaction valve R in such a manner as to cause application only of the trailer brakes. In the embodiment shown in Fig. 1, actuation of the brake pedal causes actuation of a master cylinder 1 to cause application of the tractor brakes through hydraulic line 2. The pressure generated in the hydraulic master cylinder system is transmitted to a plunger 24 in the reaction valve R to cause deflection of a diaphragm 10 so that first a seating 14 on disc 11a secured on diaphragm 10 engages a valve member 15 to shut-off that side of the chamber from a vacuum reservoir, vacuum normally existing in valve chamber 9 via pipe line 6a, port 12 and aperture in disc 11 secured to diaphragm 10, and then the valve assembly 15, 17 is displaced, moving a valve member 21 away from its seating after first lifting a poppet valve 34 and connecting that side of the chamber to atmosphere to establish the required pressure differential across the piston in the trailer servo 3. When the trailer brake application only is required, a hand brake lever 33 is actuated to rock lever 31 and, through rod 30, effect displacement of the plunger 24 which in turn displaces the diaphragm 10 to effect operation of the trailer brake servo in the manner above described. A further embodiment is disclosed in the Specification in which a modified reactor valve R is inserted in a system employing a straight vacuum-type trailer brake servo.

Abstract: 1,033,109. Valves. DOWTY HYDRAULIC UNITS Ltd. July 8, 1964 [July 19, 1963], No. 28747/63. Heading F2V. A number of valves, each controlling one or more fluid-actuated motors, are arranged in a bank, the fluid supply and exhaust being connected to the first and last valves, respectively, in the bank; each valve is of the sliding type having a spool 26 which is housed in a bore with exhaust grooves 62, 64, 67, a supply groove 65, motor grooves 60, 61 and inlet grooves 63, 66. The latter are open to the supply groove 65 via a spring-closed fluid-actuated valve 73. With the spool urged into the neutral position shown by a centring spring 58 the valve 73 is closed since an orifice 74 provides for fluid from the supply groove 65 to act on both sides of the valve; the inlet grooves 63, 66 are closed by the spool. Upon moving the spool to one or other of two operating positions, one motor groove 60, 61 is connected to its adjacent exhaust groove 67, 62 whilst the other motor part is connected to its associated inlet groove 63, 66. The valve 73 is lifted and aligns ports 79 therein with fixed ports 80, 81 so that fluid flows through orifice 74, and ports 79, 80, 81 into the open motor groove 60 or 61 via the open inlet groove 63, 66. Should the flow rate to the motor exceed a given value the valve 73 is further lifted to uncover ports 82 leading to the exhaust groove 64. A ball check-valve may be disposed in the valve 73 to seat upon the orifice 74. Each fluidactuated valve may be physically separated from its related sliding valve.

By saturating the transformers but not the reactors, high voltage is provided for the motor 1 connected to the transformers while by saturating the reactors but not the transformers a lower voltage is provided. Intermediate voltages are obtained by varying the saturation of the reactors with the transformers de-saturated, the lowest voltage being obtained when both transformers and reactors are desaturated. Instead of saturable auto-transformers non-saturable auto-transformers with paired saturable reactors connected in parallel with part thereof may be used (Fig. 2, not shown). Fig. 3 shows the control arrangement in which a control current in D.C. circuit 18 saturates the reactor pair 10 and de-saturates the self-saturating reactor pair 11 to produce a D.C. output in main control circuit 15 (Fig. 1) instead of the output in main control circuit 14 obtained with zero control current in 18. If the control current in 18 is increased sufficiently, both reactor pairs 10 and 11 are saturated and the voltage in circuit 9 appears across choke 16 so that no D.C. outputs pass through main control circuits 14, 15 to the control windings of the transformers and reactors.
