IPC: D06L4/30
Abstract: 135,516. Watremez, E. T. J. Nov. 8, 1918, [Convention date]. Bleaching and washing, processes and materials for.-Fibres of vegetable origin are scoured to facilitate subsequent bleaching in a bath obtained by treating a metal such as zinc or metallic oxide simultaneously with an alkali, an alkaline hypochlorite, and a soluble reducing-salt. The metal used must give a colourless solution with an excess of alkali and be adapted easily to form reducing-compounds. The alkali may be added' after the salts. The mixture, apart from its reducing properties, possesses a considerable affinity for the natural colouring-matter of the fibres. The bath is preferably heated to boiling-point, when.. to retain its alkalinity, it may be necessary to add alkali. After treatment, the substances remaining in the fibre are precipitated by slaked lime. The precipitated substances are subsequently removed by immersion first in the ammoniacal, and then in an acid, bath. Instead of adding slaked lime to the bath, a separate bath of milk of lime may be used, especially if the operation has been performed in the cold.

Title: Jet milling
IPC: B02C19/06
Filed: 1972-03-24
Abstract: 1324219 Jet mills LINDE AG 24 March 1972 [2 July 1971] 13794/72 Heading B2A Low-temperature jet milling apparatus 1, Fig. 1, comprises, in sequence in a propellant-gas flow line, a compressor 2, a heat exchanger 5, a jet mill 6 and a separator 10. In operation, material to be ground is fed from a duct 7 by a screw-feeder 8 into a cold propellant gas stream and is thus submitted in the jet mill 6. Conveying gas is compressed at 2, the heat of compression is removed in a water cooler 4 and the pre-cooled gas is fed via the heat exchanger 5 which further cools it to the jet mill 6 along a line 3. Ground material leaves the mill at 9 and passes to the separator 10. The product is discharged to a collector (not shown). The cold expanded gas is fed from the separator 10 to an adsorption device 15 and thence to a refrigerator 11 (working with a liquefied gas coolant). Cold gas is branched partly to the feed duct 7 to precool the material and partly to the heat exchanger 5, whence it is either recycled to the compressor 2 or discharged to atmosphere. In a further embodiment the heat exchanger 18, Fig. 2, jet mill 16 and separator 19 may form an integral unit surrounded by an insulating jacket 20. Compressed propellant gas carried by a line 3 is from the compressor 2, Fig. 1, is cooled in the heat exchanger 18 prior to being fed to the jet mill, by expanded cold propellant gas which may itself be cooled by an external-source on passage through a line 23. After passage through the milling chamber the gas and ground material bears via an opening 25 and is conveyed by a line 26 to a chamber 21 which is surrounded by the separator 19. Comminuted particles are collected in a chamber 22. A fraction of the separated expanded propellant gas is supplied from the chamber 21 to a duct 17 through which material to be ground is fed so as to embrittle the material prior to milling.

Title: Improvements in or relating to antennae
IPC: H01Q7/04
Filed: 1952-05-30
Abstract: 753,565. Aerials; radio navigation. STANDARD TELEPHONES & CABLES, Ltd. May 30, 1952 [June 2, 1951], No. 13817/52. Addition to 677,860 and 680,512. Class 40 (7). An aerial assembly suitable for use in an omnidirectional radio beacon comprises a small dipole 2 rotatable by a motor 3 to give a rotating figure-of-eight pattern in the horizontal plane, the energy having a polarization perpendicular to the axis of rotation. Above the dipole is a gapped loop aerial 5 in the form of a circular conductive disc 14 having a number of slots 19, 20, 21, 22 cut in its circumference and energized cophasally to provide a substantially circular radiation pattern in the same plane as the polarization plane of the dipole aerial. Both the aerials 2 and 5 are enclosed within a hollow metallic resonator structure consisting of the centre part of the ground plane disc 1, the disc 7 and a plurality of spaced conductive rods 8. The rods, which are longer than half a wavelength at the mid operating frequency, are sufficiently close together to pass only the horizontally polarized energy. To overcome the tendency for energy with vertical polarization to be radiated from the upper and lower ends of the resonator the cage-like structure is extended upwardly as. indicated by the three sections 9, 10 and 11. In order to load the short dipole properly it is surrounded by a second inner cage composed of the appropriate part of the disc 1, the circular disc 14 and a plurality of vertically disposed rods 13. The spacing between the upper and lower ends of this cage is made less than half a wavelength so that resonator action is inductive to help compensate for the capacitive reactance of the short dipole. Further matching means in the form of open-ended stubs 16 and matching device 16A may also be provided. The omnidirectional aerial is energized by means of a feeder 17 led up one of the rods 8 as shown at 18 and connected to a central junction box 23 from which branch feeders 24 extend up one side of each slot to the outer end where the inner conductor is led across the slot (as at 25) and continued in a matching stub 26 on the opposite side. Adjustable shorting bars 27 control the electrical length of the slot. Coaxial lines 24 and 26 are selected so that, so far as the rotating. dipole is concerned, the omnidirectional aerial behaves as if it were a plain conductive disc and there is no mutual interaction. In operation as a beacon a reference signal generated by a tone-wheel 37 driven from the dipole drive motor is fed to modulate the transmitter 30 along with voice and station identification signals. The reference signal is frequency modulated in accordance with dipole position. Modulation is removed at 31 from the energy fed over relay 32 to the dipole 2 whilst it remains on the energy fed over relay 34 to the omnidirectional aerial 5. The relays may be operated to bring into use stand-by equipment 29.

Abstract: 1,263,135. Automatic lathes. PITTLER MASCHINENFABRIK A.G. 17 March, 1969 [28 March, 1968], No. 13853/69. Heading B3T. A multi-spindle automatic lathe comprises spindles 2 in an indexible spindle drum 1, a number of hydraulically actuable double clutches 5, 6 for engaging spindle drives and braking the spindles, each double clutch being associated, with a respective spindle, and an hydraulic valve 14 capable of distributing fluid to a selected double clutch to engage its associated spindle with the spindle drive, or to brake the spindle, independently of the other spindles. Each double clutch includes a first clutch 5 which, when engaged transmits drive from a common drive-shaft 3 via a respective gear 4 to the associated spindle; and a second clutch 6 which, when engaged, acts to brake the associated spindle. The clutch operating means is a piston 10 which acts on a pivoted lever 9 to shift a slip-ring 8 to engage or disengage a clutch 5 or 6. Each piston 10 receives fluid from the valve 14 via a distributer 13 associated with the respective spindles. The common hydraulic valve 14 comprises a part 17 which is indexible with the spindle drum, a control bushing 16 and a central valve stem (not shown). The valve can be arranged, by selective use of removable plugs, to distribute fluid to the part 17 such that a spindle will, in a selected index position, receive fluid to cause it to be driven, braked or in neutral. The valve 14 also controls operation of a piston 12 for operating the spindle chuck. The latter can be operated only in one index position, this being selected from a lever 15. Preferably, six spindles are provided.

Abstract: 778,979. Phonographs. INDUSTRIAKTIEBOLAGET LUXOR. May 13, 1955 [May 25, 1954], No. 13916/55. Class 40 (2). A support member or a separate feeling member on the pick-up arm 1 releases mechanism operating to disconnect the pick-up arm 1 from the drive mechanism, not shown, of a phonograph after the known sensing of the outer edge of a record, not shown, in a device for placing the pick-up arm needle 5 in the correct initial playing position on a sound disc gramophone record to be played irrespective of the diameter thereof; this device is applicable to that kind of phonograph in which before the playing of a record the pick-up arm 1 is set down on the record, by the phonograph drive mechanism at a distance from its rotational centre not exceeding the radius of the initial turn of the round groove in a record of the smallest diameter to be played, and also in which the support member on the pick-up arm carries the arm on the record and prevents the needle 5 engaging the record when the arm is subsequently moved by the drive mechanism towards the record edge on arrival at which edge the needle is brought into engagement with the initial turn of the sound groove and the support member is moved upwards to a position above the horizontal plane through the needle point in order not to prevent playing of the record. As shown, the support member is a roller 17 and the device comprises two stirrups 6, 7 pivoted on a pin 8 and on the former of which the roller 17 is mounted. The stirrup 7 is urged upwardly by a tension spring 10 to a position determined by an adjustment screw 11 and the two stirrups 6, 7 have respectively cam edges 14 . . . 16 and a slot 12 which are engaged by the end 18 of a rectangular section rod 19 connected through a lever 20 and another rod 22 to a notched wheel 3 driven by the drive mechanism and rotatable upon the shaft 2 by which the arm 1 may be swung horizontally, a tension spring 24 urging the lever 20 in such direction that the rod 22 is disengaged from the wheel 3. In operation, at rest the rod 19 is held by an edge 13 in slot 12 and when the arm 1 is set down at the centre of a record contact by the roller 17 causes a slight anticlockwise movement of stirrup 6 which permits movement to the left by rod 19 but the latter movement is limited by the stop edge 16. By the engagement of rod 22 with wheel 3 the arm 1 is swung radially outwardly across the record and the roller remains below the needle 5 until it drops off the edge of the record, whereupon the needle engages the starting arm of the groove and the stirrup 6 drops, disengaging stop edge 16 from the end 18 and permitting rod 19 to move to the left until end 18 engages the stop edge 15, whereupon the spring 24 acting through rod 19 pivots the stirrup 6 anticlockwise until the roller 17 is above the record surface and also disengages the rod 22 from the wheel 3 to stop the horizontal swinging movement of the arm. Specification 554,282 is referred to.

Title: Improvements in and relating to the Windings of Electric Inductance Coils and other Apparatus.
IPC: H01F30/08
Filed: 1916-10-03
Abstract: 109,129. British Thomson - Houston Co., (General Electric Co.). Oct. 3, 1916. Solenoids.-For protection against surges and other high-pressure disturbances, the windings of reactance coils and other electrical apparatus are separated by material which is substantially insulating under ordinary pressures but becomes conductive under excessive pressures. The material may be distributed uniformly throughout the colls or it may be graduated from the ends towards the middle of the coil or coils. Fig. 1 shows in elevation a reactance consisting of several superposed and ventilated coils 16, on a plate 25 carried by insulators 26. Each coil consists of a number of turns, partially embedded in plastic material, as shown in plan in Fig. 2. The turns are preferably wound conically as indicated in section in Fig. 7 and are connected at their inner and outer ends alternately. The plastic material may be uniformly semi-conducting throughout, but preferably the resistance is graduated either by varying the thickness or the composition. In the arrangement indicated in Fig. 7 the leakage increases towards the terminals, though this arrangement may be reversed. The filling parts 30, 31 may be of plastic insulating-material. In another arrangement coils embedded in semi-conducting material may be separated by coils embedded in insulating- material.
