Title: The manufacture of colouring matters of the anthraquinone series
IPC: C09B61/00
Filed: 1933-03-30
Abstract: Coloured anthraquinone compounds are obtained by separating the pigment-bearing mycelium from a cultivation of moulds of the sub - genus Cylindro-Helminthosporium (Nisikado) of the genus Helminthosporium in a suitable medium, e.g. Czapek-Dox medium, drying and powdering the mycelium, extracting with an aqueous alkali or organic solvent and, if desired, purifying the product by recrystallization.  According to examples: H. gramineum Rabenhorst, H. catenarium and H. tritico vulgaris Nisikado are grown on a Czapek-Dox medium containing glucose, sodium nitrate, potassium dihydrogen phosphate, potassium chloride, magnesium sulphate, and ferrous sulphate and water of a pH value of 8,0 with sodium hydroxide, and from the mycelia coloured products consisting of helminthosporin (4 : 5 : 8-trihydroxy-2-methylanthraquinone) together with catenarin (4 : 5 : 8-trihydroxy-2-hydroxymethylanthraquinone) pure catenarin, and catenarin together with triticosporin (1 : 3 : 5 : 8-tetrahydroxy-2-hydroxymethylanthraquinone, are isolated by means of ethyl ether, chloroform or acetone; H. cynodontis (Marignoni) previously grown on Czapek-Dox agar, is grown on the above-mentioned medium and the mycelia extracted with chloroform to give cynodontin (1 : 4 : 5 : 8-tetrahydroxy-2-methyl anthraquinone); and H. euchl n (Zimmermann) gives the same product.  The cultimation media may contain as further specified sources of carbon, starch, sucrose, maltose, fructose or mannose, and molasses, and as sources of nitrogen, nitrates, ammonium salts, proteins and their breakdown products; it is advantageous to sub-cultivate the moulds as in some of the examples above.

Title: Improvements in or relating to feeding devices for pilger rolling mills
IPC: B21B21/06
Filed: 1932-04-04
Abstract: 395,465. Rolling - mandrel carriages. MANNESMANNRÍHRENWERKE, 1B, Berger Ufer, D³sseldorf, Germany. April 4, 1932, No. 9657. Convention date, April 10, 1931. Addition to 344,750. [Class 83 (iv).] The rotation of the helicallygrooved spindle g of the pilger mandrel d in its nut i which ratchets in the casing h as on the parent Specification, is controlled by mechanism coupled to the spindle g and causing the rotation of the casing relative to the ratchet and spindle to compensate the angle of rotation of the mandrel d in accordance with the length of its stroke. The spindle q oscillates a second nut i<1> on another helically-grooved spindle j, the rotation of which is transmitted through gear wheels 1, 2 and a hollow shaft 3 to a rod 6 connected to the casing h. The amount and direction of rotation given in the casing h is determined by mounting the connecting-rod 6 on a slide block 5 which can be traversed along a slide 4 fixed on the rocking shaft 3, by hand or by an electric motor 7 coupled by chain and bevel gearing to a screw which slides the block 5 along, and thereby varies the throw and direction of pull of the connecting-rod 6 on the casing h of the ratchet nut i.

Title: Fluid-tight passage at the end of a channel of a nuclear reactor cooled by an organic liquid
IPC: G21C1/16
Filed: 1964-03-06
Abstract: 1,025,546. Reactors. EUROPEAN ATOMIC ENERGY COMMUNITY (EURATOM). March 6, 1964 [March 13, 1963], No. 9669/64. Heading G6C. A sealing system is provided for sealing between an extension of a reactor callander tube and a pressure tube therein in a nuclear reactor cooled and moderated by different liquids, the sealing system utilizing the sealing effect of frozen coolant within the seal. The coolant may be organic, e.g. a polyphenyl, and one part of the sealing system includes a moving valve member for regulating coolant flow in the associated pressure tube. Referring now to Fig. 1, the reactor moderator tank 3 has projecting from it a tube 2 which is in effect an extension of the zirconium callander tube 4. The pressure tube 1, of sintered aluminium, extends downwards to an outlet 12 for reactor coolant. A uranium carbide fuel rod 7 is supported within the pressure tube by a rod 8, tube 8<1> and rod 9. A scavenging and thermal insulating gas is injected at 13 to fill the annular space between the pressure tube 1 and the callander tube 6 (and extension). Two seals are provided for preventing leakage of reactor coolant from its system adjacent the pressure tube end, i.e. a first annular seal 17 to prevent reactor coolant entering the annular space 6 between the pressure and callander tubes, and a second annular seal 24 between the fuel support rod 9 and the callander tube 2. Both joints are cooled by water circulation on the opposite side of a flexible member of zigzag section, on the opposite side of which the reactor coolant freezes to form the seal. Two types of seal coolant circulation are illustrated for the top seal, 17 using simple flow through an annular zone, and 17<1> using a flow through a helical groove 14. The lower seal is movable to effect opening and closing of valve member 21, and thus has two sealing surfaces cooled by up- and downcomer coolant passes. The rod 9 is moved upwards to displace the fuel element 7 so that a fuel handling grapple can be attached thereto without it being exposed to full core radiation.

[Class 98 (i).] An X-ray installation, for example of the portable kind, is supplied with electric energy from a generator coupled to one or more mechanically-driven road wheels of a vehicle turning clear of the ground. The current for energizing the generator may be drawn from a storage battery present on the vehicle for lighting &c. purposes, or from the dynamo for charging said battery. As shown in the Figure, one of the rear wheels 11 of a car 10 may be run up an incline 9 on a skid 7 until it rests on and drives a pair of rollers 8. The other rear wheel may rest on the ground or be similarly supported on loosely-rotating rollers. The A.C. generator 6 is coupled directly, or by gear wheels, belt, chain, or flexible shaft, to one of the rollers 8, and supplies the transformer 5 which energizes the X-ray tube 2. In a modification, the generator is combined with one of the rollers 8, its stator being surrounded by a rotor which is driven by the wheel 11. Motion of the vehicle may be prevented by props, or by braking the front wheel, or by anchoring the vehicle to the skid as by a steel wire, or by so mounting one of the rollers 8 that it may be raised vertically to prevent the wheel 11 from descending from the skid.

Converting direct currents.-The light interrupting means in a system of indicating light strength as described in the parent Specification is operated by the receiver system. Fig. 1 shows a selenium cell 6 and a thermionic audio-frequency amplifying system of which the valve 9<a> serves as a detector to operate a signalling device when the cell ceases to be subjected to an interrupted light beam as described in the parent Specification. The electromagnet 23 arranged in the plate circuit of the valve 9<a> is adapted to energize a tuning fork 22 one limb of which interrupts the light beam at a focus point 3. The interrupter may be rendered self-starting by arranging a condenser 24 so adjusted that the circuit 23, 24 is resoant. To avoid " burning glass" action sun cones 40, 40<a> may be provided. Instead of a tuning fork a vibratory reed carrying a mirror 31, Fig. 6, may be employed and a duplex light cell or two light cells 6<b> with mirrors 38 may be used. In modifications, discs provided with a number of armatures are rotated by one or more electromagnets arranged in the plate circuit of the valve 9<a> and the discs may be slotted or carry mirrors to interrupt or reflect the light.
