Patent GB-266735-A (GB)
Title: Improvements in the treatment of crude nitrate of soda (caliche)
IPC: C01D9/02
Filed: 1927-02-24
Abstract: 266,735. I. G. Farbenindustrie Akt.- Ges. Feb. 24, 1926, [Convention date]. Sodium nitrate. - Crude nitrate of soda (caliche) is subjected at ordinary temperatures, say 15-30‹ C., to prolonged treatment with water in such quantity that the sodium nitrate is almost completely dissolved, whilst a large proportion of the other soluble salts, such as sodium chloride and sodium sulphate, remain with the residue, the solution so obtained being employed hot at 60-100‹ C. to leach a fresh batch of caliche, and the final solution being cooled to deposit the sodium nitrate. The mother liquor remaining, if necessary after dilution, may replace the water used in the first instance, and the cold leaching may be applied to the residues remaining after any warm leaching operation, for instance, those obtained in the second step of the process. In an example, 900 Kgs of caliche containing 25 per cent of sodium nitrate, 25 per cent of sodium chloride, 20 per cent of sodium sulphate, and 30 per cent of insoluble matter are treated with 800 litres of water at 20‹ C., the resulting solution, containing all the sodium nitrate and sodium chloride present, and 65 kgs. of sodium sulphate, being used hot to leach a fresh batch of caliche. If the crude caliche contains more than 25 per cent of sodium chloride, the cold leaching should be so conducted as to leave a part thereof in the residue. The weight of water used for the cold leaching operation should not, in general, exceed the weight of the soluble constituents present in the caliche.

Title: Improvements in or relating to the manufacture of mandrels for use in blind riveting
IPC: B21J15/36
Filed: 1953-02-26
Abstract: 749,257. Blind riveting; forging mandrels for blind riveting. BRITISH UNITED SHOE MACHINERY CO., Ltd., DIGGLE, H. A., and LOVETT, A. E. May 25, 1954 [Feb. 26, 1953], No. 5342/53. Class 83 (4). In the manufacture of " break-head " or " break-stem " mandrels for blind riveting by the steps of heading a length of wire stock W projecting from a pair of gripping dies 2, 4, releasing the dies, feeding the stock forwardly by one mandrel length and cutting off the mandrel, the necking 48 of the mandrel stem is performed before the mandrel length of wire enters the dies. The necking is performed by tools 32, 34 disposed rearwardly of the dies. The lower die 4 and the lower necking tool 34 are fixed and the upper die and tool 2, 32 respectively are operated in unison by a rocking lever 10, Fig. 5, pivoted at 12 and actuated by a link 14. The lever carries an adjustable stud 8 which engages an extension 2<SP>1</SP> of the upper die 2 and an adjustable stud 36 which engages a part 321 of the upper necking tool 32. By adjusting the stud 36 the depth of the necking 48 may be varied. Hooks 18, 40 withdraw the die and tool during the upstroke of the lever. The heading tool 28 has a recess 30 which forms a conical head on the mandrel. A pair of cutting and pointing tools 26 are provided. The wire is fed by a mechanism of the kind described in Specification 622,705. The position of the necking tools axially of the wire may be varied for changing the position of the neck relative to the head of the finished mandrel. Various forms of neck, Figs. 8-11 (not shown) may be provided by the use of different necking tools. Specifications 555,804, 558,156, [Group VII], 738,741 and 738,760 also are referred to.
Patent GB-768245-A (GB)
Title: Electrolytic grinding apparatus
IPC: B23H5/08
Filed: 1954-02-24
Abstract: 768,245. Automatic control systems for electrolytic grinders. NORTON GRINDING WHEEL CO., Ltd. Feb. 24, 1954 [March 16, 1953], No. 5413/54. Class 38 (4). The invention relates to automatic load current limiting in an electrolytic grinder. The electrolytic cell formed by the work W, Fig. 7, and a single conducting ring CR1 on the grinding wheel is supplied with D.C. from a rectifier bridge RB, the latter being energized from an A.C. source 73 over a saturable transformer TR. A control winding 83 on the transformer carries the D.C. load current, so that, if the current flowing across the work-ring interface exceeds a critical safety value, the transformer saturates to reduce the coupling between the transformer primary and secondary windings, and thus decrease the voltage applied to the load. This decrease in voltage is enhanced by the increased voltage drop across an inductor 91, in series with the transformer primary windings, resulting from the increase in magnetizing current drawn by the primary windings when the transformer coupling is reduced. The inductor 91 may have a secondary winding in series opposition to the transformer secondaries, Fig. 9 (not shown). With a grinding wheel having a plurality of conducting rings CR2-CR4, Fig. 8, the D.C. control current required to saturate the transformer is normally shared equally between the windings 83a-83c carrying the respective work-ring interface currents; but as a result of inequalities between these currents, the current at any interface may exceed its critical safety value before the transformer saturates to reduce the applied voltage. In order to prevent this, solenoid windings 104 in series with the interfaces control shunt paths across the interfaces. Thus, if the current at any interface drops to zero or a low value, the energization of the respective winding 104 decreases sufficiently to allow its bell-crank 115 to turn clockwise under spring action, thereby causing a member 118 to close a shunt path across the interface and thus permit continued energization of the respective transformer control winding at the original shared level. If, however, an interface current exceeds the critical value, the increased energization of the respective winding 104 allows its bell-crank 115 to turn anti-clockwise against the bias of a spring-loaded arm 120, thereby increasing the pressure of member 118 on one of carbon piles CP2-CP4 connected respectively in shunt across the interfaces. The resistance of the pile is thus reduced to permit the shunting of an increased proportion of the interface current, while the respective control winding has an increased energization resulting in a tendency for the transformer to saturate. An inductor 91, provided in series with the transformer primary windings for a purpose already described, may have a secondary winding in series opposition to the transformer secondaries.

Title: Improvements in and connected with transformers of the static type
IPC: G05F3/06
Filed: 1931-02-21
Abstract: 379,667. Regulating transformers ; automatic regulation. NICHOLSON, H. G., Britannia Works, Colchester, Essex. Feb. 21, 1931, No. 5527. [Classes 38 (ii) and 38 (iv).] In a regulating transformer, the primary winding 3 or at least a part thereof is made to embrace an auxiliary magnetic circuit 1 on which is provided an opposing winding the current in which is caused to increase with load on the transformer thus causing the resultant flux linking the primary winding to decrease and tending to produce an increase in secondary voltage. In the arrangement shown, the opposing winding 7 is connected in series with a winding 9 on a second auxiliary core 8 to a source of constant voltage (e.g. the source to which the primary 3 is connected). The impedance of the winding 9 is caused to decrease with increasing load current by providing on the core 8 a coil 10 in series with the main secondary 4 so as to produce a flux opposed to that due to the winding 9. In a modification, Fig. 3 (not shown), the second auxiliary core 8 is dispensed with, and some of the turns of the main secondary 4 are made to embrace the auxiliary magnetic circuit 1 so as to produce directly therein a flux opposed to that produced by primary. An auxiliary saturating winding may be provided. In a further modification, Fig. 4, the two auxiliary cores of the first arrangement are combined in a single three-limbed magnetic circuit 13 having the primary turns and the winding 7 arranged on the outer limbs, and the winding 10 in series with the main secondary disposed on the centre limb. The flux opposing that produced by the primary turns in the auxiliary magnetic circuit may be additionally controlled bv manual or automatic variation of the magnitude or phase of the current in an additional coil provided on the auxiliary magnetic circuit.

Filed: 1942-04-29
Abstract: 558,655. Earth-moving machines. BURNS, J. S.April 29, 1942, No. 5765. [Class 68 (i)] In an earth-moving machine, such as a bulldozer, angle-dozer, trail builder or bull-grader, in which an earthmoving blade is adjustably carried in front of a selfpropelled vehicle of tractor or crawler type, the blade support includes a pair of parallel linkages extending longitudinally one on each side of the vehicle and connected to the blade in such manner that the blade thrust subjects the upper side links to compression and so relieves the lower links. A tractor 1 is mounted on crawler tracks 4, 5, which have a leaf spring suspension 10 and oscillate about a pivot 8 preferably coinciding with the axis of the rear track-driving sprockets 9. Plates 16, bolted to the track subframes, have welded thereto bearing brackets 17, forming extensions of the pivot 8, upon which are mounted vertical posts 18, 19, welded &c. at their upper ends to the tractor main frame The posts 18, 19, carry the rear journals 15, 26 for the channelled upper and lower links 27, 28, of a parallel linkage, the front vertical links 29 of which are upstanding portions of a front cross member 30; the journals 25, 26, are preferably , equally spaced above and below the pivot 8, the arrangement being such that during working, the upper links 27 are in compression, due to building-up of the spoil,.whereby the lower links may be of lighter construction. Intermediate bracing links 39 are provided, and the lower links carry rollers 40 running on cheek plates 41 to relieve side strain. If the machine is to be used for bulldozing only, the mouldboard 31 and blade 32 constitute the cross member 30; if, however, it is also to be used for angle-dozing, the member 30 is angled, the mouldboard 31 being pivoted thereto at 34 and adjusted by means of pivoted aims 46 held in adjusted position by pins 49 passed through guide channels 45 projecting from the vertical links 29.

Patent GB-1045546-A (GB)
Title: Improvements in apparatus for effecting therapeutic treatment
Inventor: KUTTIG HELMUT
IPC: A61N5/10
Filed: 1964-02-12
Abstract: In apparatus for therapeutic treatment of a disease, e.g cancer, a beam of ionising radiation, e.g. g -, X- or b - rays and a beam of V.H.F. or micro-wave radiation, are directed at a particular diseased point in the patients body, in such a way that the two beams intersect only at this point, the apparatus being arranged so that either the emitter of the ionising radiation moves around the patient or the patient is arranged to be rotated in the path of the ionising radiation beam.  The diseased part is first of all irradiated by the V.H.F. or micro-wave radiation, e.g. decimetre waves of about 69 cms. wavelength, in order to heat the diseased part, rendering it hyperaemic and therefore increasing the effectiveness of the treatment by the ionising rays which follow.  The arrangements described also avoid irradiation, by ionising rays, of healthy tissue which has already been subjected to decimetre radiation.  In a first embodiment (Fig. 1, not shown) the patient 1 sits upright on a rotating stool 17, driven by a motor 19.  The axis of rotation, 1a, passes through the point 2 to be treated.  The positions of the ionising ray emitter 3 and decimetre ray emitter 9 and of the patient are adjustable so that the intersection of the beams can be accurately located.  In a second embodiment (Fig. 2, not shown), the patient 1 lies on a couch 17a and the two emitters are mounted on a framework 21a, 7a which is arranged to rotate about an axis 1a through the point 2.  To ensure that the ionising beam does not pass through healthy tissue previously irradiated by source 9a, the emitters may be mounted at substantially different angles a ,b  to the axis 1a.  If a  and b  are equal, rotation should be through an angle not greater than 180 degrees.  In a third embodiment (Fig. 3, not shown), the emitter 3b, for the ionising rays, is arranged to describe a tightening spiral on a spherical surface 30, the centre of which coincides with the point 2.  The emitter 9b is connected rigidly to the emitter 3b, and is arranged to irradiate different zones of the healthy tissue only after the ionising beam 6b has already passed through.  The drive for this arrangement comprises a motor 22b which rotates the whole framework about an axis 1a, coupled with a rope 47 which is reeled up as the framework revolves, causing movement of the emitter mounting up the guide groove 46a.  A time lag may be provided between the initial operation of the decimetre source 9 and the source 3 to arrange preheating of the diseased part, but this is not necessary when the treatment time is long.
