Title: Gibberellic acid
IPC: C12P27/00
Filed: 1958-04-28
Abstract: Gibberellic acid is recovered from solutions containing it by treating the solution of gibberellic acid with an ion-exchange resin and eluting from the ion exchange resin the gibberellic acid adsorbed on it.  The starting solution may be uncontaminated mixtures of fermentation broths in which the acid is produced. Suitable ionexchange resins are the strongly basic, polymeric, nitrogenous anion exchange resin class.  The process may be conducted column-wise or batchwise.  Prior to adsorption a fermentation broth is first screened, filtered or centrifuged to separate any solid particles. For elution an aqueous solution containing an electrolyte is used; e.g., aqueous acidic solutions such as aqueous solutions of hydrochloric or acetic acid admixed with a suitable organic solvent such as an alcohol or ketone, e.g. methanol, isopropanol or acetone. Examples describe the recovery of gibberellic acid using various ion exchange resins and elutrients.

Title: Process for making steel
IPC: C21C5/32
Filed: 1959-04-20
Abstract: A process of producing steel from a pig iron containing more than 0.30% phosphorus by a top blowing method comprises the following stages:-Stage 1.-Pure oxygen is blown on to or into the melt through a lance held at a constant height above the surface.  Stage 2.-Top blowing is continued using a lime-oxygen suspension while the tip of the lance is gradually lowered; the bath is then deslagged and  Stage 3.-Top blowing is continued with oxygen containing a finely divided alkaline earth compound.  Lime may be suspended in the oxygen blast during stage 1 in addition to slag forming materials added to the bath before blowing.  The oxygen lance may be inclined from the vertical to promote foaming of the slag after which it is moved to the vertical position.  During the second stage the lance may be moved slowly and steadily downwards or may be lowered and raised each minute resulting in a downward movement of 0.05 to 0.10 m. per minute.  After deslagging preceding the third stage silica may be added before or with the alkaline earth compound.  Specifications 745,205, 789,892 and 844,987 are referred to.

Title: A device for reducing armature reaction in dynamo electric machines of the homopolar type
IPC: H02M3/40
Filed: 1930-05-05
Abstract: 360,418. Dynamo-electric machines. PLATEN, B. C. VON, 6, Lilla Baltgatan, Stockholm. May 5, 1930, No. 13757. Convention date, May 3, 1929. [Class 35.] Polepieces, armatures and field magnets, dampers on cores of; inductor machines; machines with two or more armatures; rotary transformers.-In a homopolar machine of the type described in Specifications 323,498 and 323,549, [both in Class 35, Dynamoelectric generators &c.], a rotary flux distributer is located axially intermediate the rotor poles adapted in conjunction with the rotor poles to reduce armature reaction. The arrangement is such as to cause damping or interruption of the armature reaction flux in all positions of the rotor. The invention is described in connection with a continuous current transformer having primary and secondary windings 9, 9<1> on stationary cores 1 .. 4 connected respectively to commutators C, C<1>. The laminated rotor poles N, S held between clamping plates which may be of copper are angularly displaced by 45‹ on the shaft 30 which carries the stationary or rotating exciting windings 7, 8. The casing 25 is of nonmagnetic material and the cores 1 .. 4 are surrounded by aluminium covers 28 which serve as damping devices. The field distributer F comprises two annular magnetic segments 31, 32, Fig. 4, separated by nonmagnetic segments 33 which extend over the overlapping surfaces of the poles N, S viewed in the axial direction. The air gap between the poles N, S and the stator cores is equal to the air gap between the stator and the flux distributer F except at the parts of the poles corresponding to the spaces 33 where the gap is twice as long. Diagrams are given showing the paths of the useful flux and also showing that the armature reaction flux when allowed to form a closed circuit, closes at one end of the rotor. Preferably the parts of the poles near the air gap only are laminated so that the armature reaction flux must pass partly through nonlaminated iron in which damping currents are set up. In order to reduce armature reaction still further, a damping coil may be provided around the path of the armature reaction through the poles, for example, the copper clamping plates of the poles may be connected by copper bolts. In the case of a generator, continuous or alternating current may be produced.

Filed: 1974-03-28
Abstract: 1448054 Aerials THOMSON-CSF 28 March 1974 [30 March 1973] 13825/74 Heading H4A A three-dimensional radar aerial which is rotatable in azimuth comprises a first feed means producing a main beam which effects a high speed scanning of space in elevation, and a second feed means operating independently of the first feed means and producing at the aperture of the aerial a secondary beam occupying a predetermined extent in elevation, in which it carries out surveillance. As described, the first feed means comprises a Robinson type aerial in which two parallel trapezoidal plates 4, 5 are so formed together as to provide a circular feed ring 3 at one end and a linear aperture at the other end. Rotation of a feed horn 2 in front of the ring 3 produces a linear displacement of the apparent source at the linear aperture, said linear aperture being extended by a flared horn 6 to a radiating aperture 60 in front of which is located a reflector 7 having an elliptical-paraboloidal surface. With the linear aperture of the Robinson type aerial vertically disposed, the radiated waves are horizontally polarized. The secondary beam is produced by a vertically disposed array of slots 9 in one wall 10 of the flared horn 6 leading to the radiating aperture 60. The array of slots is fed by means of a rectangular waveguide 8, which is supplied at one end 11 and is terminated at the other end 12 by an absorbent load 13. The radiated waves from the array of slots 9 are vertically polarized, and their entry into the Robinson type aerial is prevented by means of a vertically disposed reflecting plate 14 in the central plane of the linear aperture thereof. Matching members may also be inserted in the horn 6. The secondary beam may be of pencil shape or, by suitably designing the array of slots, it may be given a special shape, such as cosec<SP>2</SP>. Another secondary source may be provided on the opposite wall 100 of the horn 6 if required (Fig. 2, not shown).

Abstract: 961,129. Wrapping machines. AVISUN CORPORATION. April 8, 1963 [June 8, 1962], No. 13933/63. Heading B8C. Fluid ejected under pressure from the face of a tucker plate 15 (Fig. 3) in a wrapping machine reduces friction between the plate and the wrapper. The fluid may be ejected through at least one passage 83 which extends partially through the plate, opens in one face and is connected to a tube 85. The passages 83 are preferably at an angle to said face and extend in the direction in which the wrapped article moves with respect to the plate. The plate may alternatively be made of a porous material, such as sintered metal particles, with all surfaces except the said face coated with an impermeable substance. The fluid may be gaseous, such as compressed air which may contain an oil mist or particles of starch or graphite, or may be a liquid such as water or oil. The compressed air may be ionized to neutralize static electrical charges on the wrapper. In the wrapping machine illustrated in Fig. 1, an article 21 is advanced by pushers 33 on an endless chain 29 along a table 17, and is pushed on to a carrier 25 and between tucker plates 15 by a plunger 23. Since a continuous web of wrapping material 37 extends across the path of the plunger 23, material is now disposed around and over a portion of the article. The carrier 25 and tucker plates 15 disposed on either side of the article pivot upwards towards top folder plates 49 causing the article to be encircled by wrapping material and the upper edge to be down-folded. The roller 55 moves downwards to form a loop of wrapping material which is then cut by a knife 57. The material falls into position for wrapping the next article. The partially wrapped article is advanced by pushers 67 between side folder blades 69 and bottom folder blades 77 to which heat sealing elements are fixed. As the article moves away from the tucker plates 15 fluid is delivered through the passages 83 to minimize friction between the plates and wrapping material and hence prevent the material unfolding.
