Patent GB-444766-A (GB)
Title: Improvements in and relating to saccharification of cellulose
Filed: 1934-09-27
Abstract: In a process for saccharifying cellulose by intermittently passing batches of dilute acid through it, such as described in Specification 367,916, each batch is employed at a lower temperature than that of the cellulose, the temperature of the latter being raised after each acid batch has passed through it and it may be to a temperature higher than that it possessed before the supply of the preceding batch of acid.  The temperature may be raised by passing steam into the cellulose from below before or during the introduction of each batch.  The acid may be forced through the cellulose by steam pressure and/or by reducing pressure below the cellulose.  The concentration of the batches may increase from batch to batch and the concentration in an individual batch may be lower in the earlier portion than in the later.  The successive batches may become progressively smaller to correspond with the shrinkage of the cellulose and in this event the time interval between batches may be made progressively smaller.  The cellulose is preferably in short fibred form as by cutting wood across the grain into plates.  To break down higher sugars such as cellobiose the extract may be after-hydrolyzed by maintaining it at a higher temperature.

Title: Improvements in or relating to fluid metering valve apparatus
Inventor: HISTON ROBERT
IPC: E03D3/04
Filed: 1951-11-30
Abstract: 708,670. Valves. WILD & CO., Ltd., A. G. Dec. 1, 1952 [Nov. 30, 1951], No. 28106/51. Class 135 A flushing device of the kind comprising an inlet 8, Fig. 2, situated above a seat for the discharge valve 5 and an outlet 9 situated below it, a sleeve 18 extending downwards from the valve serving to guide the latter throughout its rising and falling movements, a hollow piston carried by the valve and having sufficient clearance from the wall of the casing to allow inlet fluid to leak into a balancing chamber above the piston, and the peripherally-projecting undersurface of the piston being acted upon by inlet pressure to lift and open the valve when the pressure in the balancing chamber is relieved by actuation of a vent valve 17, is characterized in that the vent valve is a sliding member and is made dead beat in action by peripheral friction means, e.g. a fibre ring 27 or a metal spring. The vent passage 11, 13 ... 15, leading from the balancing chamber is normally closed by a disc valve 17 pressed upwards on to its seat by the pressure of the liquid in the chamber. Valve 17 is pushed off of its seat by means of a spring- returned knob 36 and tappet 34. Rotation of the sleeve and piston is prevented by a set-screw 21 riding in a slot or groove in the sleeve. The main discharge takes place into the interior of the sleeve through apertures 19. Towards the end of its upward movement, piston 5 contacts an abutment 28 depending from valve 17 and forces the latter on to its seat to enable pressure to be built up again in the balancing chamber to close valve 4. When valve 17 is seated, the valve and abutment 28 constitute a dead stop limiting upward movement of the piston. The discharge through passages 13 ... 15 may be controlled by an adjustable throttle. Inlet pressure is maintained constant by a spring-pressed disc valve 42, Fig. 4, the loading spring 41 of which may be of bi-metallic construction to correct for changes in viscosity of the liquid. Specification 621,103 is referred to.

Title: Improvements in multi-range hook-on electrical indicating instrument
IPC: G01R1/22
Filed: 1962-07-23
Abstract: 966,443. Electrical measuring instruments. GENERAL ELECTRIC CO. July 23, 1962 [Sept. 1, 1961 ], No. 28181/62. Heading G1Q. A multi range electrical instrument of the hook-on type has a magnetic core 6, 7 which opens and closes to permit location about a conductor 8, and an indicator 4 of the rotating vane moving iron type responding to the flux in the core so that alternating current in the conductor 8 may be measured, and is characterized by having an electrically isolated coil 24 positioned about the core and a switch 9 to shunt this coil with an impedance 27. When the shunt is switched in, the effective range of the instrument is increased because the induced currents in the coil produce a field in the magnetic core which opposes that produced by currents flowing in the conductor 8. The instrument is provided with input leads 10, 11, 12 which are arranged to enable it also to be used to measure voltage and resistance. For measuring voltage, probes 57 and 58 are provided which apply the voltage across the coil 24, an appropriate range being chosen by setting the switch 9 to either contact 50 or 51. For measuring resistance a battery 61 and a variable resistance 62 are incorporated within a housing 63, and the battery acts so as to pass a current through the coil 24 and the unknown resistance, which is connected between the probes 58 and 60. In both these measurements the current through the coil 24 creates a magnetic flux which rotates the vane 36 and consequently the pointer 4 to give the required indication on the scale 3.

Title: Improved pressure control apparatus for use with steam generators
IPC: F23D11/46
Filed: 1950-11-21
Abstract: 687,677. Controlling liquid fuel burners WEBB, H. W. B. Nov. 21, 1950 [Nov. 30 1949], No. 28464/50. Class 75(i) [Also in Group XXIX] A pressure control apparatus for a steam generator which utilizes a liquid fuel burner comprises means by which the rate of fuel discharge from the burner may be controlled in accordance with the rate of rise or fall of pressure of the steam generated. In a steam generator including a liquid fuel burner 2, Fig. 1 of the kind controlled by an air influenced piston in a chamber having a breather port through which air is allowed to escape freely during normal operation of the burner, but on restricting or preventing such escape the fuel discharge from the burner is reduced, the flow through the breather port 2a is controlled by a valve device CD influenced by the difference in pressures at opposite sides of an oriflce valve 7 through which an ballast chamber 6 is connected with a preheater device 4 disposed beneath a steam separator 3. The control device CD includes a valve member 10, Fig. 2, controlling the air flow to an outlet 16 from an inlet 14 connected to the breather port 2a, and actuated by a bellows 11 receiving water under pressure through a pipe 9 from the preheater side of the orifice valve 7. The valve member 10 is also controlled by a diaphragm 17 subjected on one side to the pressure within the bellows 11, the other side being connected through a pipe 8 to the ballast chamber side of the orifice valve 7. A spring 12 adjustable in compression by a screwed member 12a determines the steam pressure under steady conditions at which the valve 10 is closed to reduce the burner discharge. A change in steam pressure in the generator causes a restricted flow of water through the orifice valve 7, and thus a difference in the pressures applied through the pipes 8, 9, depending on the rate of change of steam pressure, to the diaphragm 17 to adjust the valve 10. Specification 672,362, [Group XIII], is referred to.

Title: Separation of liquid hydrocarbon mixtures using a liquefied, normally gaseous polar selective solvent
IPC: C10G21/14
Filed: 1961-08-04
Abstract: Liquid hydrocarbon mixtures are separated by separating the mixture into raffinate and extract phases by liquid-liquid extraction with a <PICT:0913629/III/1> liquefied normally gaseous polar selective solvent, contacting at least a part of the raffinate phase with a solid selective adsorbent, and desorbing the adsorbate from the adsorbent with a portion of the liquefied solvents.  Suitable solvents include sulphur dioxide or ammonia, which may also contain monomethylamine.  Suitable adsorbents include silica gel, alumina, silicaalumina cracking catalysts, and fluorosilicates. The process may be used to remove colour bodies and polar compounds, especially aromatic, from distillates such as heavy naphtha, kerosene and diesel fuels to obtain products such as odourless kerosene, transformer oils, white oils, and high luminometer number thermally stable jet fuels; or alternatively the process may be used to obtain the polar compounds.  The Figure is a flow diagram illustrating the process according to the invention, in which a kerosene feed is passed via line 10 to a liquid-liquid extractor 11, where it flows in counter-current to liquefied sulphur dioxide introduced via line 12. Raffinate is removed via line 17 and passed to a solvent recovery system 18, to which the extract phase is also passed via line 16, from which the sulphur dioxide is withdrawn via line 19 and condenser 20 to reservoir 21.  The raffinate and extract are separately stripped of solvent.  A substantially SO2-free raffinate is removed via line 22 and valve 23 to adsorption system 24, from which low-aromatic product is removed via line 27 and valve 26 to stripper 28, where final traces of SO2 are removed, and the finished raffinate product is withdrawn via line 31.  The adsorbent is desorbed by liquid SO2 introduced via line 32 and valve 33, and the effluent is obtained passed to recovery system 18.  Extract products recovered from extraction and adsorption are removed via line 37.  Solvent is next removed from the adsorbent either by reduction of pressure of increase of temperature or both.  Specification 659,241 is referred to.
