Patent GB-767016-A (GB)
Title: Improvements in or relating to the preparation of specimens of incongruently melting phases
IPC: C30B13/00
Filed: 1953-12-01
Abstract: A substantially homogeneous specimen of an incongruently melting phase (e.g. a compound or solid solution formed by a peritectic reaction) in a binary or pseudobinary system, the specimen having a composition which is richer in the component which depresses the freezing point of the phase than the limiting composition at the maximum temperature at which the phase exists, is prepared by forming a body of solid material from the components of the phase in overall proportions approximately the same as those of the desired specimen and then subjecting the body to a fractional fusion process.  The fractional fusion process may consist in a single pass of a single molten zone and/or a pass of a number of molten zones in one direction followed by the pass of an equal number of molten zones in a reverse direction, this double passage being repeated if necessary. The body of solid material which is treated may be an ingot produced by directionally freezing a melt of the components of the phase in appropriate proportions or may be compact mass of intimately mixed powders of the components of this phase in appropriate proportions. The mean composition of the directionally frozen ingot may be altered by cutting off one end of the ingot and the composition of the powder body at the first molten zone may be chosen so that the zone deposits solid material of a composition the same as that of the rest of the powder body.  A component of the phase may be added to the molten zone after it has been formed and the molten zone may be agitated, e.g. mechanically or by ultrasonic vibrations.  Part of the body on either side of the molten zone may be cooled.

Title: Process and apparatus for the production of magnesium chloride
IPC: C01F5/34
Filed: 1960-09-29
Abstract: Dry magnesium chloride is obtained by two-stage drying of aqueous solutions thereof by pre-drying the solution in a spray drier or an evaporator, or both, and drying the resultant lower hydrate in a flash drier, the gas effluent from the flash drier being maintained at a temperature which is at most 40% below its inlet temperature, such effluent gas being then used for heating the spray drier and/or evaporator to which the initial solution is charged. As shown in Fig. 1, the first stage is made up of a pre-evaporator 7 to which the solution is initially fed followed by a spray drier 1, the latter being fed with hot gas through pipe 5 and the hot effluent from the second stage flash drier through line 15. The hydrate formed is separated at 10 and passed through a conveyer to a flash drier 2 where it is contacted with hot gas from line 17 and entrained therein. Separation of the final product is effected in 13 and the hot effluent gases return through line 15 to the spray drier 1. Spray drier effluent gases withdrawn from separator 10 are employed to heat the pre-evaporator 7. In a specific example <PICT:0959385/C1/1> air is fed through line 17 at 450 DEG  C. to the flash drier 2 and the effluent therefrom must be at least 240 DEG C.(at most 40% lower than the inlet temperature) before being fed through line 15 to the spray drier 1. Hot gas at 550 DEG  C. is fed through line 5 tangentially to the spray drier 1 whereby the residual moisture content of the magnesium chloride is reduced to 15-25%.  The gases separated from this intermediate product and now at a temperature of 150 DEG  C. are fed to the pre-evaporator 7 from which they may be withdrawn at temperatures below 100 DEG  C.

Title: A process for dyeing and printing with hydrazine derivatives of tetrazaporphin dyes and textile materials dyed therewith
Inventor: DISTLER HARRY
IPC: C09B47/26
Filed: 1960-09-30
Abstract: Textile materials, such as those of natural or regenerated cellulose, cellulose esters, polyamides, polyesters or polyacrylonitrile, are dyed or printed, and if desired quality finished, by applying a dye of the tetrazaporphin series, such as a metallised or unmetallised phthalocyanine, which contains one or more sulphonic acid hydrazide groups. or an N-methylol or etherified N-methylol derivative of such a dye, and also applying, together with or after the dye, an acid or acid-reacting substance and a hardenable aminoplast, or the initial materials for forming the same, and finally heating.  When the dye contains N-methylol groups, treatment only with the nitrogenous component of the aminoplast may be applied.  The dye may also be converted into its N-methylol derivative on the fibre by treatment with an alkaline formaldehyde solution.  Specified hardenable aminoplasts are dimethylolurea, dimethyldimethylolurea, dimethyloldicyandiamide, methylolthiourea, dimethylolguanidine, trimethylolmelamine, diphenyldimethylolurea, and methylol derivatives of monoureines, diureines, carboxylic acid amides and diamides, urethanes, polyurethanes, hexahydro - keto - triazines, lactams, polyamides and ethylene ureas.  Specified acids and acid-reacting substances are boric, phosphoric, formic, acetic, glycollic, tartaric, chloracetic, chlorpropionic, citric and maleic acids and ammonium chloride and diethanolamine hydrochloride.  The dyes are prepared by reacting tetrazaporphin derivatives containing sulphonic acid chloride radicals with hydrazines, such as hydrazine itself, methyl-, ethyl-, propyl-, butyl-, cyclohexyl-, phenyl-, and benzyl-hydrazine, 1 - hydrazino - benzene - 4 - sulphonic acid, acetly-hydrazine, benzoyl-hydrazine, semicarbazide, thiosemicarbazide and aminoguanidine.  The dyes may also contain sulphonic acid groups, and are converted into their N-methylol derivatives by treatment with alkaline formaldehyde solution, and, in turn, into their etherified N-methylol derivatives by treatment with alcohols in the presence of acids.  Examples of dyeing, and of the preparation of the dyes used therein, are given.

Title: Apparatus for recording the passage of a missile past a target
IPC: G03B15/16
Filed: 1960-09-30
Abstract: 1511478 Photographing moving objects DE HAVILLAND AIRCRAFT CO Ltd 8 Sept 1961 [30 Sept 1960] 33610/60 Heading G2A Apparatus for recording the passage of a missile past a target comprises an array of photo-sensitive detectors on the target centred on an axis parallel or nearly so to the intended relative path of the missile part of the target, the response from the array being used to operate at least one pair of wide angle single shot cameras disposed on an axis normal to the array axis. In Fig. 1 the target aircraft 10 is provided with six sets 20 each of two similar wide angle single shot cameras, one pair of sets being on the top and bottom of each engine and one pair in the nose of the aircraft. The sets of cameras of each pair are disposed in opposite directions on axes normal to the longitudinal axis of the aircraft and each camera has a hemispherical field of view. Also mounted on the nose of the aircraft is an array of photo-sensitive detectors 28 centred on the axis of the aircraft and including two optical systems by each of which radiations in a field of view 30 of defined angular width are admitted. The optical systems are disposed on opposite sides of the nose and face in opposite directions, each field of view having an extent slightly greater than 180 degrees in a plane normal to the axis of the aircraft. In operation a missile 18 provided with a heat source, e.g. a jet pipe or observation flare, is discharged towards the target aircraft and causes a pulse in the photo-sensitive cells as it enters and as it leaves the field of view 30. The first pulse opens a gate, Fig. 3 (not shown), and the second pulse passes through the gate to operate the first camera of each set. The cameras being triangulated, the resultant photographs disclose the exact track of the missile. A further missile can be launched against the target and photographs taken by the second cameras. If the target is turning at or less than its maximum rate of turn, pulses produced by the sun or a false source of radiant energy follow each other with too long an interval, and the circuit prevents the cameras being operated. Difficulties in discrimination against the sun or other false sources may arise with the use of a single beam array, and in a second embodiment, Fig. 2 (not shown), the optical system provides two fields of view centred in conical surfaces lying at 80 degrees and 100 degrees to the axis of the aircraft. A missile on a course nearly parallel to the target will then produce two pulses sufficiently closely spaced to operate the cameras, but if the missile is travelling at right angles to the target the pulses will be too widely spaced and the cameras will not be operated. To obviate this difficulty a further detector array may be provided mounted on an axis normal to the aircraft axis, Fig. 4 (not shown). In a modification of this arrangement, Fig. 5 (not shown), the fields of view of the arrays are centred on axes at 45 degrees to the vertical and horizontal.
