Abstract: 1,076,059. Separating water from fuel. J. L. McQUERRY & W. W. LOWREY. July 7, 1965, No. 28844/65. Heading B1D. [Also in Division F4] In the fuel supply line to a diesel engine is provided the device shown which preheats the fuel means of the engine exhaust gases and at the same time causes water and other foreign matter to separate out of the fuel before the latter passes to the engine. The device comprises concentric tubular elements 42, 43 providing therebetween an annular space the upper portion of which is subdivided by baffles 46, 48, 50, 52, 54 into compartments interconnected only by narrow gaps between neighbouring baffles as shown. The baffles are so disposed that the fuel which enters the space through two inlets 22, 24 must pass through a number of the narrow gaps before reaching the outlet 26, and in so doing the water and other foreign matter separates out and collects in the baffle-free, relatively stagnant, lowermost zone from which it is withdrawn through a valved outlet 60. The fuel after leaving the device at 26 passes through a filter 32 (Fig 1 not shown) before it reaches the engine. Exhaust gases from the engine are collected by a scoop (38 Fig. 5) and passed by way of a duct 40 (which may be flexible) through the inner tube 42 of the device in order to heat the fuel. The gases leave the tube 42 through a perforated end plate 56.

Abstract: 1,267,567. Automatic voltage control. UNION CARBIDE CORP. June 9, 1969 [June 18, 1968], No.29074/69. Heading G3R. In a D.C. voltage regulator of the type comprising a plurality of series-connected D. C. cells a, b, c---n (e.g. fuel, thermionic, solar or a battery), a series regulating transistor Q1 (or transistor tetrode), a driver transistor Q2 and control members 16, 18, 20, the efficiency is improved over a known arrangement Fig. 1 (not shown) by using only a predetermined number of the cells to develop the necessary base drive for the transistor Ql. To this end, the collector of transistor Q2 is connected to a tapping on the cell chain through a resistor R1 whose value need only be low (e.g. to act as a current limiting device), the resistor power loss thereby being reduced. The circuit shown is otherwise conventional and typical component values are given to illustrate the improved efficiency. The value of resistor R1 is determined by the voltage tapped from the chain of cells.

A container for preserving substances to be mixed at the time of their utilization comprises a bottle containing one of said substances and formed with a tube having a normally closed end on which a cylindrical stopper of compressible material and a cap member threaded with its lower end on said stopper are adapted to slide, said cap member containing the other substance, means for allowing the bottle and cap member to communicate with one another through said tube when the contents are about to be utilized, for mixing both substances, the bottle being provided with another tube or orifice for extracting the mixture. As shown, the container comprises a bottle 1 containing a solvent L and having a tube 2 integral therewith at its upper end and another tube 3 laterally of the main body of the bottle 1. The tube member 2 is provided with an orifice 4 which is normally closed by an annular stopper 5, preferably of rubber. Threaded on this stopper is a cylindrical closed cap member 6 having a restricted portion 6a and an enlarged portion 6b and containing a solid 5. The cap member is under vacuum. In use, the orifice 4 is uncovered by sliding the cap 6 and stopper 5 towards the bottle 1, the bottle is turned upside down until the solid in the cap has been dissolved by the liquid flowing from the bottle and is then put back in its original position. The ends of the tube member 3 and cap 6 are broken and the solution withdrawn through the arm 3. In a modification, Figs. 2 and 3 (not shown), the tube on which the cap and stopper slide extends downwardly to a short distance from the bottom of the bottle, the orifice is adjacent the lower end of the tube and a file mark is made on the tube at a level just above the upper end of the stopper.

Title: The preparation of acrylic esters
IPC: C07C51/14
Filed: 1957-09-16
Abstract: Acrylic esters are prepared by dissolving acetylene in a solvent and reacting it with carbon monoxide and a C1-12 aliphatic, monohydric alcohol in the presence of a catalyst known to catalyse the reaction at 220-270 DEG , preferably 240-250 DEG  C., and 2000-4500, preferably 2500-3500 p.s.i.  The reactant alcohol is the preferred solvent.  Other suitable solvents include dioxan, tetrahydrofuran and water.  The reaction may be carried out batchwise or continuously. The alcohol may be primary, secondary or tertiary and is preferably used in slight excess.  Generally 0.5 to 5 per cent by weight based on the alcohol of a catalyst such as a nickel halide is used.  In examples: (1) methyl acrylate is prepared by dissolving acetylene in methanol and then reacting with carbon monoxide using a nickel bromide catalyst; by-products are mainly dimethyl ether; (2) 2-methylhexyl acrylate is similarly prepared from 2-methylhexanol.

MHD apparatus, e.g. a generator, comprises a plasma chamber defined between two concentric parallel discs 1, Fig. 1, an arrangement for producing a magnetic field perpendicular to the discs, and electrodes for collecting the current generated in the plasma, each disc being formed of an assembly of sector-shaped cells 8, and each cell comprising an assembly of elements 9 arranged substantially perpendicular to the axis of symmetry of the cell. The field is produced by two coils 3 located one adjacent each of the discs 1, and the coils may be superconductive. The plasma is produced by a burner 2 and flows radially between the discs, the height of the elements 9 decreasing from the centre of the discs to the periphery so that a divergent plasma chamber is produced. The elements at the same radical distance from the centre of each disc are assembled to form a polygonal member, the elements of each cell 8 being radially spaced and insulated from one another by an inert gas flowing in the spaces between them. The elements 9 are made of metal and include pipes for coolant flow, the pipes of adjacent elements being interconnected. An anode and cathode respectively located at the centre and periphery of the plasma chamber each comprise, on each disc, a plurality of jets of hot liquid metal directed into the plasma. If seeding is employed, the seed metal may be the same as that used in the jets. Adjacent jets of liquid metal are insulated by a jet of insulative gas located between them and directed into the chamber from the discs.

[Also in Group XX] The resilient characteristics of the tube 5 of a Bourdon gauge are supplemented by a spring 14 whose strength is chosen for each tube 5 to compensate for differences between tubes 5 when mass produced and thus to produce a predetermined reading on a fixed scale 10 when a predetermined pressure is applied to the tube 5. The strength is calculated by measuring the amount of overshoot of the pointer for a predetermined pressure. The spring 14 is connected between a fixed part 9 and the spindle 8 of a pointer movable in scale 10 by deflection of tube 5. If the tube 5 is connected to a reservoir the pressure in the tube depends on the temperature of the fluid in the reservoir and the scale 10 may be calibrated directly in units of temperature.

Fig. 1 shows apparatus in which, for this purpose, a part of the incoming mixture (air) is drawn off at the points B, C or B<1>, C<1> and is freed from carbon dioxide by chemical or other means in apparatus H afterwards passing through an interchanger G and a liquefier L to the separating column. The liquefier is cooled by the nitrogen from the lower part of the column which is afterwards expanded in a motor M and returned with nitrogen from the upper part through exchangers R<2>, R<1> to the regenerators. In the exchangers it cools the liquid oxygen and nitrogen passing from the lower to the upper part of the column. Fig. 2 shows a modification in which the mixture is delivered partly through regenerators 0, O<1> and partly, after removal of carbon dioxide, under pressure through an exchanger H. A part of the separated product is drawn off from the regenerator and passed through the exchanger cooling the incoming mixture therein which is expanded in a motor M before passing to the separating column.
