Patent GB-765636-A (GB)
Title: Manufacture of sulphur dyestuffs
IPC: C09B49/12
Filed: 1955-03-14
Abstract: The invention comprises sulphur dyes obtainable by chlorinating decacyclene with sulphuryl chloride at a temperature not above the boiling point of the sulphuryl chloride and treating the product thus obtained, which contains 8-10 or more atoms of chlorine per molecule, with sulphur at above 250 DEG C.  The chlorination may be performed in presence of an indifferent diluent, e.g. monochlorbenzene, and in presence of a chlorination catalyst such as iron, iron salts, aluminium chloride, iodine.  An example describes the treatment of decacyclene with sulphuryl chloride in presence of iron at 20-40 DEG C., and heating the isolated, ground reaction product, containing 45 per cent chlorine, with sulphur at 250-270 DEG C.  The product dyes cotton brown shades which may be after-treated with a mixture of potassium chromate and copper sulphate.  Specification 468,627 [Group IV] is referred to.

Title: Improvements relating to methods of and apparatus for controlling the amount of thread wound on a bobbin
IPC: B65H63/08
Filed: 1956-03-09
Abstract: 787,549. Photo-electric control of winding bobbins. ROSENKRANZ, C. G., HALSTENBACH, H., and PLUTTE, A., [trading as HALSTENBACH & CO.]. March 9, 1956 [April 19, 1955], No. 7509/56. Class 40 (3). [Also in Group IX] A method of controlling the mount of thread wound on to a bobbin uses the interruption by the winding of light falling on a photoelectric cell to control the winding process. In machines having the thread guide, in a bearing member moved parallel to the bobbin by a traversing gear as the winding proceeds, the apparatus for realizing the method is a gauging device arranged in the bearing member and consisting of a light source and a photo-cell connected via an amplifier to a control relay which responds when the cell illumination falls below a predetermined level, the relay acting on the traversing gear so that the bearing member is accelerated. In the embodiment described, light source 12 and photo-conductive cell 13 are fitted in bearing member 1 at the place corresponding to where the conical part of the winding merges into its cylindrical part. When light to the cell is blocked sufficiently for its resistance to increase to the point where valve 18 cuts off, contacts 19<SP>1</SP> of relay 19 energize control relay 22 whose armature is thereby attracted so as to engage pawl 23 in toothed wheel 35, movable around threaded spindle 11, which forms part of differential gear 32, 33, 34, 35. Wheel 35 being thus stopped, spindle 11 accelerates and member 1 moves further during each to and fro oscillation of thread guide 2 caused by roller 4 on rotating cam 6, and the winding diameter decreases. The resulting increased light into the photo-cell causes relay 19 to be energized, the control relay de-energized, and spindle 11 decelerated to its normal speed until the light beam is interrupted once more; a winding of uniform diameter is thus built up. The sensitivity of the gauging device can be increased by reducing the effective illuminated surface of the photo-cell, and by adjustment of potentiometer 21 in the amplifier the diameter wound can be varied. The Specification includes two variants of the optical system as shown in Fig. 1 (see Figs. 5 and 6 (not shown) ; in one variant two mirrors are used.

Abstract: 724,308. Pen and pencil holders. SCROLL PENS, Ltd. May, 28, 1953 [March 20, 1953], No. 7772/53. Class 146 (3). A writing instrument has a barrel housing an axially spring-retractable writing unit, such as a pencil or a ballpoint pen, and a plunger for axially projecting the unit from the barrel: As shown, a ball-point pen b is slidable in a barrel comprising parts a and a<SP>1</SP>. The rear end b<SP>2</SP> of the pen b is engaged by a rod d that may be locked in projected position by a spring detent e. The rod d is projected by depression of a spring-retracted press-button g rotatable on the end of a plunger h carrying an eccentric spigot engaging the pen end b<SP>2</SP>. The plunger h has helical cam slots engaged by a fixed pin k, arranged such that at each depression and each retraction of the button g, the plunger h and thus the spigot l are rotated through 90 degrees. In this manner, the detent e is released by the spigot l to permit retraction of the pen b. In a modification, the cam slots may be in the barrel, while the plunger carries a cam-engaging pin. In a further modification, the rod d may be extended to replace the forward part of the plunger h, the extension being notched to form a detent.

Title: Improvements relating to the heat treatment of alloyed or unalloyed cast iron
IPC: C21C1/10
Filed: 1947-03-22
Abstract: Alloyed or unalloyed grey cast iron which as cast contains graphite in the form of spheroidal particles is heated to a temperature close to but below the alpha gamma transformation point to cause combined carbon in the basic mass to transform to graphite.  The temperature may be not more than 45 DEG C. below the alpha gamma transformation point, preferably 685-710 DEG C., and the cast iron maintained at that temperature for two hours.  This treatment may be preceded by heating for two hours at a temperature between the alpha gamma transformation point and 985 DEG C., preferably 815-955 DEG C., and cooled by any method e.g. in the furnace, in a pit, or quenched.  The cast iron may contain 2-4.5 per cent carbon, 1.3-3.5 per cent silicon, 0.05-0.2 per cent magnesium, up to 4 per cent nickel, a trace of molybdenum, 0.5-0.8 per cent chromium, 0.8-1.0 per cent manganese, up to 2 per cent copper, and up to 0.5 per cent phosphorus.  Specification 630,070 is referred to.  The Provisional Specification states that the temperature may be not more than 75 DEG F. (41.6 DEG C.) below the alpha gamma transformation point, and that the cast iron so treated is particularly applicable to railway, agricultural and motor vehicle parts.

IPC: C07C201/16
Filed: 1961-03-06
Abstract: Mixtures of isomeric dihalonitrobenzenes, one isomer of which has a halogen atom in a position ortho to the nitro group, are separated by reacting the mixture at a temperature of at least 120 DEG C. with a specified inorganic cyanide in the presence of an organic diluent hereinafter specified, thus preferentially converting the said isomer to a halogenated ortho-cyanonitrobenzene, and then separating this orthocyanitrobenzene from the other unchanged isomer e.g., by steam distillation or solvent extraction with light petroleum. Inorganic cyanides specified are alkali-metal cyanides, cuprous cyanide, a mixture of an alkali-metal cyanide and cuprous cyanide, or an alkali metal cyanide-cuprous cyanide complex. Organic diluents specified are tertiary amines, such as pyridine, dialkylcarbonamides, such as dimethylformamide, and dialkylsulphoxides, such as dimethyl sulphoxide. An inert diluent such as an aromatic hydrocarbon, nitrobenzene or chlorobenzene may also be present. The halogen substituents in the isomers may be chlorine, bromine or iodine. Examples are given, illustrating the separation of mixtures of 2:3-dichloronitrobenzen and 3:4-dichloronitrobenzene, by conversion of the former into a mixture of the 2,5- and 3,4-dihalonitrobenzenes may also be similarly treated.

The input terminals are connected together by a coaxial line 20 of characteristic impedance Z having a slotted portion 15 which accommodates a variable tap 16. The hybrid ring shown has four branches each one quarter wavelength long at the operating frequency, the branches 2, 4 having a characteristic impedance Z and the branches 3, 5 a characteristic impedance Z/#2, where Z is the impedance presented by the antennµ 10, 11. The tap 16 is connected by a line 17 of impedance Z/2 to the source 18 whose impedance has the value Z/2.

Two or more such circuits may be connected in cascade, one of the output terminals 6, 7 being connected directly to the variable tap of the next circuit and so on. The circuit may be used for reception in which case the variable taps are used to select the contribution of each receiving antennae to the total input signal applied to a receiver 18.
