Title: Improvements in core covering spindle adapters
IPC: D02G3/36
Filed: 1949-06-10
Abstract: 659,657. Covering cores by winding. UNITED STATES RUBBER CO. June 10, 1949, No. 15494. Convention date, June 18, 1948. [Class 109] In a core covering device having a hollow spindle 11 adapted to support a package 12 of covering yarn and rotate it about a core passing upwardly through the spindle, an adapter is provided comprising a thick disc 14 having means for fitting the spindle and the upper end of the package to centre the latter upon the spindle, the disc having a thick outer edge and a deep recess in its upper face mounting a traveller ring 19 of less diameter than the disc so that the traveller 20 for the covering yarn travels on the ring in a path lying inwardly from the thick outer edge of the disc and enables the yarn to rest against this edge as it passes to the traveller. in the form shown in Fig. 2, which represents the motor driven type of core covering unit, the hollow spindle 11 is integral with the central shaft of the motor. In this case the adapter comprises the disc 14 together with a barrel 15 rigidly secured thereto, the inner bore of the barrel fitting the spindle snugly and its outer bore fitting the tubular liner 13 of the package snugly. An annular recess 18 receives the projecting end of the tube 13. The traveller ring 19 is arranged below the top of the combined disc and barrel. The spindle extends a substantial distance above the adapter so that, together with the guiding edge of the disc 14, the yarn is held out of dragging engagement with the traveller ring 19. The yarn is thus subjected to minimum tension during the covering operation, thus enabling high speeds to be used without excessive breakage. In the form shown in Fig. 4, which represents the belt driven type of core covering unit, the hollow spindle 23 is fitted into a casting 22 extending upwardly from a whorl 21 driven by the belt. An annular disc 24 secured to the whorl is provided with four prongs 25 which snugly engage the inner bore of the tubular liner 27 of the yarn package 26. In this case the adapter comprises the disc 28 with a rigidly secured tube supporting disc 30 fixed to a central tube 31 whose inner bore fits the hollow spindle 23 and also the hollow spindle 35. The disc 30 is provided with the prongs 30<1> which also engage the inner bore of the liner 27 of the package 26. The recess 32 is provided to clear the upper end of the liner 27. The traveller ring 33 is arranged as before with the same advantages.

Title: Improvements in or relating to gauging devices, for example, for use in gauging or sorting machines
IPC: B07C5/06
Filed: 1941-12-03
Abstract: 554,501. Gauges ; sorting. RUAU, F. F., and MOLINS MACHINE CO., Ltd. Dec. 3, 1941, No. 15574. [Class 106 (ii)] A gauging device comprises two pairs of jaws, one pair being adapted to engage a workpiece and the other a test piece, wherein one jaw of one pair is arranged to move bodily with one jaw of the other pair, wherein movement of a jaw of one pair is arranged to be limited by a stop on a jaw of the other pair, and wherein an article to be gauged is placed between a pair of gauging jaws and according to the thickness of the article the test-piece between the other pair of jaws is either gripped or remains free. As shown in Fig. 2, levers 1, 2 are hinged together by flat spring 5, and are urged apart by compression spring 6, the movement being limited by lugs 11, 14. The work piece W.P. is positioned between a pre-set screw 7 and a sliding pin 10, and the slip gauge G.P. between pin 10 and fixed pin 13 on bracket 12, and when spring 6 is released, if the work piece is of correct size, the gauge can be moved freely, but if the work piece is over size, the gauge is gripped. In Fig. 1 (not shown) and Fig. 3, the arrangement of parts is modified, so that the slip gauge is gripped only when the work piece is under size. The invention is applied to a sorting machine in Fig. 3, where the gauge is automatically applied with its jaws open to the workpieces in succession. If the slip gauge is gripped, a periodic rearward movement of the device pulls member 25 to release a trapdoor under the work piece, which is thereby rejected. The opening and closing of the jaws are controlled by cam 28.

Patent GB-457525-A (GB)
Title: Improvements in the manufacture and production of valuable azo dyestuffs
IPC: C09B45/16
Filed: 1935-05-29
Abstract: Azo dyes are manufactured by coupling diazotized aromatic amines containing a hydroxy or carboxylic acid group in o-position to the amino group, or their derivatives, with aromatic maleic acid amides which, in addition to the amino group combined with the maleic acid radicle, contain, in the aromatic radicle, an amino or hydroxy group (coupling taking place in o-position thereto), and, if desired, other substituents.  Alternatively the diazo compounds are coupled with aromatic amines which contain either at least two amino groups or at least one amino group and one hydroxy group and, if desired, other substituents, the coupling being effect in o-position to a hydroxy or amino group, and the dyestuffs are then converted into the corresponding maleic acid amides, e.g. by treatment with maleic anhydride in the presence of acid-binding agents.  The products may be converted into complex metal compounds by treatment in substance or on the fibre with agents supplying metals, whilst those free from sulphonic acid groups are suitable for dyeing by the single bath chroming process.  In examples: (1) 1-amino-2-hydroxy-5-chlorobenzene-3-sulphonic acid is diazotized and coupled with 2 : 6- or 1 : 7-maleylaminonaphthol; the products yield blue-black to black and blue-green to greenish-black after-chromed shades respectively on wool; (2) 1-amino-2-hydroxy-4-nitrobenzene is diazotized and coupled with 2-maleylamino-6-naphthol; the product yields green-grey shades on wool by the single bath chroming process; (3) 1-amino-2-hydroxy-5-chlorobenzene is diazotized and coupled with 2 : 5 : 7- or 1 : 8 : 4-maleylaminonaphtholsulphonic acid; the products dye wool respectively red shades changeing to reddish blue on after-chroming and violet shades changing to grey; (4) 1-amino-2-hydroxy-5-nitrobenzene-3-sulphonic acid is diazotized and coupled with m-phenylenediamine and the resulting dyestuff is treated with maleic anhydride in the presence of caustic soda; the product yields brown after-chromed shades on wool.  Other coupling components specified are 1-maleylamino-5-naphthol,, 1-maleylamino-4-hydroxybenzene, 1-methyl-2-maleylamino-4-aminobenzene, N-maleyl-1 : 3-phenylenediamine-4-sulphonic acid and 6-maleylamino - 8 - hydroxyquinoline.  Specification 11228/95, [Class 2], is referred to. Maleic acid amides employed as coupling components are obtainable by condensing maleic anhydride in alkaline medium with the corresponding aromatic amine.  In an example, 2-amino-6-naphthol is dissolved in caustic soda solution and sodium acetate is added followed by maleic anhydride, to produce 2-maleylamino-6-naphthol. 1-Maleylamino-7-naphthol is obtained in analogous manner.

Abstract: 1314498 Reactor pressure vessels COMMISSARIAT A L'ENERGIE ATOMIQUE 5 April 1972 [9 April 1971 13 May 1971] 15689/72 Heading G6C A nuclear reactor installation comprises a prestressed concrete, axially vertical pressure vessel 1 an upper part of which has therein a main cavity 3 containing the reactor core 4, and a lower part of which, below the core, has vertical cavities 12 connected at their top ends to ;he main cavity and at their bottom ends with the bottom surface of the vessel, the vertical cavities serving to house thermal energy extraction apparatus. In the embodiment shown the cavities 12 have bottom plugs 13 located in a pit 14 beneath the pressure vessel which rests on radial bearing elements 14a. The disposition of the cavities 12 is such as to leave a central concrete block 15 below the main cavity. In another embodiment (Fig. 3, not shown), which utilizes spherical fue elements, the latter are discharged downwards from the core by a device (16) positioned in the central concrete block. In a further embodiment (Figs. 4 and 5, not shown), the reactor, which is a fast neutron reactor, has a thick neutron and heat shield (17) disposed around the core and at the periphery of the main cavity. The shield can be partly cooled by cold gas returning to the core. Fuel charging and discharging is conducted from the bottom of the main cavity by devices (18) disposed in the central concrete block. Some of the vertical cavities are of smaller size than others and receive auxiliary cooling devices. In another embodiment (Fig. 6, not shown) the lower part of the pressure vessel is of reduced diameter defining a shoulder (23) whereby the vessel rests on support structures (24).  In general, the reactor coolant gas may be CO 2  or He. The reactor may be thermal (using prismatic or spherical fuel elements), fast or HTR. The thermal energy extraction apparatus may comprise heat exchangers &c. or gas turbines. The arrangement of the vertical cavities enables hot gas to pass downwards through the thermal energy extraction apparatus and cool gas to pass upwards around that apparatus and adjacent the pressure vessel wall before returning to the core. The vessel mounting arrangement is said to afford increased stability in earthquakes; the pit 14 facilitates maintenance of the apparatus in the cavities.

Abstract: 119,867. Aarts, J. G., and Aarts, C. J. G. Oct. 10, 1917, [Convention date]. Sulphatizing.-Sulphide ores are sulphatized by roasting the ore, mixed with an iron compound or other catalyst if sufficient iron is not originally present, at above 800‹ C., and afterwards exposing the product to the action of the roast gases. The temperature may be diminished, for example from 800‹ C. to 500‹ C., while the roast gases and the ore are moved in the same direction. Ores having a low percentage of sulphur may be mixed with sulphur or pyrites before roasting. In some cases, the sulphatizing may he stopped at such a temperature that sulphates of only certain of the metals present are formed. Ores of zinc, copper, nickel, silver, cadmium, cobalt, and manganese are mentioned. The Specification as open to inspection under Sect. 91 (3) (a) describes also the treatment of oxide or other ores containing no sulphur. This subject-matter does not appear in the Specification as accepted.

Abstract: 951,288. Road sweeping machines. H. B. KEOGH, and L. D. E. EBELING. April 25, 1962, No. 15844/62. Heading E1G. A frame 2 supporting a side broom 1 is connected to a road sweeping machine 15 by links 12 pivoted on bearings 16 on the frame, the axis of the bearings being located farther away from the machine than the centre of gravity of the broom and frame assembly so that the assembly tends to swing away from the machine towards the road kerb under the influence of gravity. Outward movement of the broom is limited by engagement of a roller 17 on the frame with a cam track 18 on the machine and inward movement by engagement of a resilient buffer 19 with the machine. Means for adjusting the height of the frame 2 comprises a chain 20 connected to the frame at 29 and to a pair of arms 22 pivoted on the machine at 23, Fig. 2B. Pivoted on the arms 22 at 26 is the ram 24 of an hydraulic cylinder 25 itself pivoted to the machine at 27. A bar 36 secured at 37 to the machine has a screw section 38 at its other end which is screwable into a collar 31 by rotation of a crank handle 33 secured to a sleeve 30 on which the collar is rigidly mounted. The sleeve is rotatable within a bearing 34 mounted on trunnions 35 between the arms 22. The relative adjustment of the screw section 38 and the collar 31 determines the extent to which the frame may be lowered, contact between the bearing 34 and the collar terminating the sliding of the bearing on the sleeve 30. When the broom is raised, the collar 31 remains to indicate the desired height of the broom assembly to a subsequent operation of the machine.

Title: Improvements in or relating to processes for making polymers and the polymeric products resulting from said processes
IPC: C08F8/00
Filed: 1948-06-14
Abstract: Acylated polystyrene is prepared by treating polystyrene, in the presence of a Friedel-Crafts catalyst, with an aliphatic monocarboxylic acid containing at least eight carbon atoms, with the corresponding acyl halide or with the anhydride, in ratios not greater than 1 mol. per 1 mol. of styrene used to produce the polystyrene.  The acyl substituent groups may have straight or branched chains which may be substituted with groups such as methyl, ethyl, propyl, butyl, pentyl, hexyl, heptyl or cyclo radicals.  The polystyrene, preferably of a molecular weight of 3000-1,000,000, may be dissolved in solvents such as ethylene or acetylene dichloride, mono- or tri-chlorobenzene, carbon tetrachloride, carbon disulphide, chloronitromethane, nitromethane or nitrobenzene.  The two latter may act as depolymerization inhibitors.  The molecular weight of the polystyrene may be reduced by milling on hot rolls or by treating a solution, e.g. in ethylene dichloride, with aluminium chloride and either removing it by washing with dilute hydrochloride or using it as an acylation catalyst after the addition of a depolymerization inhibitor.  In examples, lauroyl, myristoyl, stearoyl, 2 - ethyl - hexanoyl, o  - cyclohexane caproyl chlorides and coconut oil fatty acid acyl chlorides are used with aluminium chloride, and myristic acid with hydrogen fluoride.  A solution of the polystyrene is added gradually to a catalyst solution with or without inhibitor, under normal or reduced pressure, the catalyst being finally destroyed by washing with dilute hydrochloric acid and water.  The product is then precipitated in alcohol and dried. The acylated products when dissolved in a mineral lubricating oil in a proportion of 0.1 to 10.0 per cent, act as viscosity-temperature improvers and pour-point depressors.  They may also be used as tackifiers in greases.  They also have adhesive properties and may be used in hot melt coatings.ALSO:Acylated polystyrene is added to mineral lubricating oil, in a proportion of 0.1 to 10.0 per cent as a viscosity-index improver and a pour - point depressor.
