Title: Improvements in or relating to the preparation of krypton with xenon
IPC: F25J3/04
Filed: 1948-10-26
Abstract: 664,838. Separation of gases. DIRECTIE VAN DE STAATSMIJNEN IN LIMBURG. Oct. 26, 1948 [Oct. 6, 1948], No. 27830/48. Class 8 (ii). Krypton and xenon are separated from the exhaust gases of an ammonia synthesis process, the hydrogen for which is obtained from water gas, by washing with liquid methane also separated from the exhaust gases to separate argon therefrom, thereby providing an argon free krypton xenon rich liquid. In operation the ammonia synthesis exhaust gases having been cooled in an exchanger 2 by returning separated methane containing argon and residual gas enter a section. 23 of a rectifying column 30 where krypton and xenon are extracted by washing with liquid methane poor in argon from a reservoir 5. The krypton and xenon carrying washing liquid traverses a line 18 and an expansion valve 19 before being separated in a column 9 into a pure krypton and xenon liquid fraction which is run off at a line 11, and gaseous methane containing argon which is expanded at a valve 20 and enters a line 32. The washing liquid for column 30 is obtained by partially condensing residual gas from the top of the column in a condenser 13 cooled by liquid nitrogen, and feeding the liquified methane containing argon through a line 42 and a sprinkler 43 to provide a second reservoir 7 with washing liquid. Overflow from the reservoir 7 cools a condenser 10 in the column 9 and the resulting methane and argon vapour combines with that in line 32 and the remainder is expanded at a valve 22 and is vaporized in a condenser 8 before traversing a line 38 and combining with gaseous methane and argon in line 32 before serving to cool high pressure nitrogen, in a line 44 of an exchanger 15, and incoming exhaust gas in the exchanger 2. The compressed nitrogen is first cooled in an exchanger 14 by returning low pressure nitrogen and after traversing boiling coils 28, 29 is liquefied by expansion in a valve 39 before traversing the condenser 13. Specification 603,249 is referred to.

Title: Method and apparatus for analysis of gases
IPC: G01N21/76
Filed: 1972-06-15
Abstract: 1379794 Analysis of gas streams COMBUSTION EQUIPMENT ASSOCIATES Inc 15 June 1972 [16 Aug 1971] 28088/72 Heading G1A In a method or apparatus, employing chemiluminescence, for the analysis of gases (such as the reactants NO 2  or ozone present in air), the sample gas is made to pass through a tortuous path thereby creating turbity and the gas is brought into contact with a surface layer of a co-reactant and the intensity of the chemiluminescence is  measured. The co-reactant may be solid, liquid or gaseous. As shown in Figs.1 and 2, the apparatus includes a base-plate 10 in one face 20 of which two channels 24, 26 defining tortuous paths of flow are formed, the other face is provided with means 12 and 14 for supplying a gaseous reactant and a co-reactant, and means 16 for withdrawing the product of the reaction. Fixed to the face 20 of base-plate 10 is a transparent pressure plate 18 with a photo-multiplier tube 22. The tortuous path for the co-reactant, which is at a higher pressure than the reactant (sample) gas, is a "dead end" path, consequently the co-reactant gas seeps as a thin layer between the face 20 and the pressure plate 18 to come in contact with the turbulent flow of the reactant gas and the resulting flashes of light are detected by the photo-multiplier 22. In a further embodiment for solid and liquid co-reactants, Figs.5 and 6 (not shown) only one path, for the sample reactant gas, is employed and the co-reactant is in the form of a strip which is held in close contact with the channel path and moves past it at a predetermined rate. If the coreactant is a liquid the strip is in the form of a web soaked in the liquid. The strip may be just a catalyst in which case an extra path for the co-reactant is provided as before. A number of examples are disclosed.

Title: Electrical energy meters
IPC: G01R21/133
Filed: 1977-07-05
Abstract: This meter exhibits a measuring mechanism which contains a multiplexer (M), an analog/digital converter (AD) and a computer (MC). The multiplexer samples current and voltage variables at time intervals and its inputs are connected to zero potential and reference potential for correcting calibration errors and for reducing the number of clock cycles of a sampling cycle. The values supplied to the computer (MC) in digital form from the multiplexer (M) and the analog/digital converter (AD) are combined with stored correction values before further processing and stored for calculating the instantaneous power since the associated input variables are sampled successively, and the sampling error is compensated for with the aid of linear interpolation or extrapolation. The instantaneous values obtained in this manner are combined with a reference frequency and supplied to memories with indicating devices. <IMAGE>

[Class 44] Fastenings of the kind in which series of members on two stringer tapes are brought into interlocking engagement by a slider and wherein the members are made of non- metallic material as described in Specification 391,146 have the members produced from a strip of material of appropriate cross-section by removing surplus material from the strip so to form the usual interlocking projections and recesses and the jaws or legs for attaching the members to the stringer tapes. A strip 16 of circular cross section, Figs. 7 and 8, is fed forward in steps and successively engaged by cutting tools. At the first step the flat base 17 is formed, at the next the sloping sides 18 and the underneath interlocking recess 19, following which the cuttings 20 and 22 are made to complete the pyramidal interlocking projection on the upper face, and finally the slot 21 is cut to form the jaws or legs and the finished member is severed from the strip. Figs. 1 and 2 show a method in which a strip 1 as shown in dotted lines is planed to the cross-section shown in full lines and thereafter by a series of cutting operations is reduced to the form shown in Fig. 2 which comprises a series of members joined side by side. The interlocking recesses on the underside, (not visible) are of oval shape formed by oscillating the drill. The members are attached to the stringer tapes, which may have a cord weaving in the thickened edge, by the softening action of a solvent. The spacing of the members on the tape may be effected by a comb template or partly finished members still connected together may be attached to the tape in that state and the connecting portions may be cut away in the finishing operation.

Title: Method of and apparatus for detecting the level of a boundary between two fluids
Inventor: CLARIDGE ANTHONY NORMAN
IPC: G01F23/24
Filed: 1962-07-23
Abstract: 953,275. Liquid level indication. ROLLSROYCE & ASSOCIATES Ltd. July 23, 1962, No. 28318/62. Heading G1H. In a method of an apparatus for detecting the level of a boundary level between two fluids in a vessel in which at least two separate elements are so located at different levels that the boundary level can be between the elements and at least are location in which both elements are in the same fluid each element is heated to a temperature above that of its immediate surroundings which is dependent on the particular one of the two fluids which is present immediately adjacent thereto and a comparison of the temperature of the elements is obtained to provide an indication of the boundary level relative to the elements. In the arrangement shown a series of vertically spaced heating elements 5 mounted in a steam generator 6 extend between the maximum and minimum water levels 8, 9. Pairs of heating elements 5 are connected in respective bridge circuits such as A, B. The bridge circuit A has alternating current supply leads 23, 24 and when both of its elements 5 are at the same temperature the bridge circuit is balanced. The bridge circuit is coupled via a transformer 25 to an amplifier unit 26 the output of which is connected to a relay coil AR. A boundary level indicating network 30 is supplied with stabilized D.C. voltage from a terminal 31 as is the amplifier 26. Each relay coil such as AR operates switches AR1, AR2, AR3 in the network. The network 30 has a common D.C. output bus-bar 32. In operation A.C. current is supplied to all bridge circuits A, B so that all the elements 5 achieve a temperature above their surroundings in the generator 6. If the water level is above the elements 5 in the bridge circuit A all the bridge circuits will be balanced and the bus bar 32 voltage will be zero. If the water level falls below the uppermost element 5 of the bridge circuit A the latter will be unbalanced and the relay coil energized and hence switches AR1, AR2 will close and switch AR3 open with the result that the bus-bar 32 is connected to the D.C. terminal 31 via switches AR1, BR4. If the water level falls below the uppermost element 5 of the bridge circuit B both bridge circuits A, B will be unbalanced and cause relay coils AR, BR to be energized. If the water level falls just below the level of the lowermost element 5 of the bridge circuit A that circuit will again be in balance and the coil AR de-energized. Hence coil BR remains energized and terminal 31 is connected to the busbar 32 via two resistors 34 and switches BR1, AR3 and CR4 and the voltage in bus-bar 32 again drops. It will be seen that by making all resistors 34 identical in value the voltage of the bus-bar 32 will vary proportionally with the water level in the generator 6. A different form of indicator network 30 may be used in which lamps are illuminated one at a time to indicate the water level.

Resistance furnaces.-The heating resistances are suspended from the refractory lining bricks bv means of a series of hooks which after insertion through holes in the brick are bent over to form keys which are engaged in grooves or seatings formed either in the brick itself or in bonded or non-rotatable sleeves or insulators applied to the brick. The hooks may be applied both to the roof and to the side walls, and are preferably made of the same kind of alloy as the resistance strips themselves, e.g. nickel-chromium alloy. Figs. 1 and 2 show hooks b fitting in holes d in a roof brick a with their turned-over ends b<2> resting in cross-grooves c, thereby locking the hooks against rotation. The ends b<2> may be held in place by the next course of bricks or in any other manner. A similar method is adopted for securing the hooks in the side walls, and, to prevent the resistance strip from becoming displaced, packing pieces of fireclay &c. may be interposed between the resistances and the bricks. The holes in the firebricks may be enlarged and fitted with insulating sleeves through which the hooks are passed; such sleeves are applied to the bricks so as to be incapable of twisting, and the grooves for receiving the key ends of the hooks may be formed in the backs or inner ends of these sleeves instead of in the backs of the bricks.
