Title: Improvement in the method of treating carbonaceous materials
IPC: C10B47/22
Filed: 1925-12-03
Abstract: 259,795. Trent, W. E. Dec. 3, 1925. Coking processes; producers. - In the distillation of carbonaceous materials such as coal or oil shale the material in a state of fine division is combined with a fluxing agent and, in suspension in a liquid or gas, is heated by passage through a hot zone to remove the volatiles and cause the ash-forming substances to combine with the fluxing agent. Suitable fluxing agents are calcium or iron oxides which combine with the silicates in the coal to form insoluble slags or sodium carbonate which forms soluble slags. These slags are separated and the carbon particles recovered in a state of fine division. When the materials are passed into contact with the heating flame partial combustion takes place so that either only the distillates are consumed or all the carbon is converted into carbon monoxide. The carbon residue and slags may be collected in water in the form of an emulsion, the fired gases escaping to a receiver, or a dry separation may be used. The oils distilled off may be mixed with the carbon residue freed from ash and used as a liquid fuel. Pulverized coal from a bin 1 is delivered through a pipe 3 into a gas or liquid stream from a pipe 4 having a pump 5. The coal may be mixed with oil before being supplied to the bin. The coal in suspension in oil or gas is heated in coils 8 by combustion in the chamber 9. A part of the gases produced is used to generate heat by being led by a pipe 12 to a burner 13 supplied with air heated in a coil 14, the remainder being passed together with the coke powder by a pipe 8<1> to the wet or dry collecting tanks 7, 7<a>. An emulsion is formed in tank 7 by the admission of water from pipes 20 and 21, the carbon and oil being subsequently separated. When the material is introduced directly into the flame valve 16 is opened and the resultant products are removed by a pipe 24 and collected in either of the receptacles 7 or 7a. Specification 171,075 is referred to.

Title: Improvements in or relating to methods of improving steel by heat-treatment
IPC: C21D1/20
Filed: 1952-12-05
Abstract: A method of treating hardenable steel containing more than 0,2 per cent carbon comprises cooling and, if desired, deforming the steel in such manner that it contains at least 50 per cent austenite at the recrystallisation temperature, deforming by at least 50 per cent in a temperature zone intermediate the recrystallisation temperature and 50 DEG C. below the temperature at which martensite formation begins but above 100 DEG C., this latter deformation being carried out so rapidly that the austenite does not pass into bainite-like or martensite-like structure, the deformed austenite being subsequently transformed to bainite or martensite.  The deformation may be produced by rolling or drawing and may be continued after the lower temperature limit has been reached until it is technically impracticable to deform further. The final transformation to bainite or martensite may be by isothermal transformation or cooling.  The deformation may be carried out during cooling between the limits or at a constant temperature.  Specifications 636,921 and 647,797, [both in Group XXII], are referred to.

Title: Improvements in or relating to ignition magnetos for internal combustion engines
IPC: H02K21/18
Filed: 1925-12-08
Abstract: 263,287. British Lighting & Ignition Co., Ltd., and Hutton, J. C. Dec. 8, 1925. Magneto-electric machines.-To obtain four or more sparks per revolution in a rotating-magnet fixed-armature magneto, such as described in Specifications 184,905, and 185,192, a set of two or more pole-pieces is fixed at each end of the armature core, the pieces at one end being displaced with regard to those at the other end in the axial direction of the machine. Fig. 1 shows a machine with a bipolar magnet giving four sparks per revolution and Fig. 2 shows an end view of the armature and pole-pieces. The limbs b, c of the armature respectively have pairs of pole-pieces d, e and h, g 180 degrees apart and are bent in opposite directions at the two ends of the armature so that the poles are separated axially by a distance k. The poles g, e are separated by gap circumferentially without overlapping, whereas the poles d, h overlap. In the position shown, flux passes from the magnet pole N through the pole d, limb b, core a, limb c, as shown in dotted lines, to the pole and magnet pole S. As the magnet rotates and its poles come successively opposite the armature poles in the order h, e; e, g; g, d the flux through the core a is successively reversed, thus giving four spares during the revolution. The overlapping poles may alternatively be on the underside of the rotor instead of above it as shown. Also, a fourpole rotary magnet may be employed, with poles of alternate sign, in which case the flux breaks occur at each of the four armature pole-pieces. Fig. 7 shows a form for giving six sparks per revolution of a bipolar magnet having six polar surfaces N, S. The axially displaced pairs of armature poles d, e, g, h are spaced at 120 degrees. In an alternative six-spark form, each end of the armature core has three poles symmetrically spaced at 120 degrees and co-operating with a magnet having two, four or six poles spaced apart by 60 degrees. Other numbers of sparks per revolution may be obtained by increasing the number of poles on the rotor or armature core or both and modifying their angular spacing. for examples, 45 degrees for eight sparks or 36 degrees for ten sparks. Specification 263,286 also is referred to.

Patent GB-313513-A (GB)
Abstract: 313,513. Sundstrand Corporation, (Assignees of Sundstrand, O. J.). June 13, 1928, [Convention date]. Adding and subtracting apparatus for monetary values.-In a machine having a number of key-set stops determining the extent of movement of actuating-racks, the pence-rack and its feeling- member are connected together for relative sliding movement, and move through different distances to provide for the larger number of divisions in the pence denomination. Means are also described for shifting the stopsetting devices relatively to the field of stops when changing over from non-decimal to decimal rotation. As shown, applied to the Sunstrand machine, wherein the type-bars 3 are set by contact of feeling-rods 46 with stop-pins 42 and in their return stroke actuate the totalizer pinions 125, through racks 129 or 130, the pence bar 3<1>, Fig. 3, is pin-and-slot connected with the foot 45 carrying the feeling rod 46. The foot is extended and notched at 54 to receive a pin 53 on the operating lever 10 pivoted at 12. Another pin 10a on the lever engages a slot in a portion of the type-bar, so that due to the different distances of the pins from the pivot 12 the stepped movements of the bar compared with those of the rod 46 are reduced in extent in the ratio of 9 : 11. To prevent the ten-shilling bar from rising more than one digit step, its feeling- rod is furnished with a sleeve to engage the sliding-carriage 47. When it is desired to set the machine for decimal computing only, a key 70 Fig. 8, is depressed to rock a lever 67 and so a lever 64, Fig. 10, having a pin-and-slot connection with a bevelled bar 59, engaging a roller 56 mounted on the bar 55, Fig. 9, supporting the column of setting-pins 80, actuated by the various digit keys. This movement of the bevelled bar withdraws its nose from the roller to allow the lever 50 to swing relatively to the bar 55 until the roller is engaged by the bracket lug 58. In this position of the parts the feeling-rods 46 of the pence, shillings and ten-shilling bars are moved to the right beyond the field of stop-pins so as not to be affected by the setting-operations. The key 70 is normally held down, when set, by a latch 70, displaced to release the key at the end of each operation by a pin 77, or the key may be retained set by a hand-operated latch plate 107. To prevent the rise of the monetary racks beyond cipher-printing position when the machine is set for decimal computation, a bail 98 Fig. 8, is rocked by a link 102, connected to the lever 67 so as to overlie lugs 101 on these racks. When a total is required, however, this bail must be removed to allow the racks to rise and for this purpose the bail is provided with an upstanding a.rm 113 lying in the path of the frame 114, Fig. 1, so as to be rocked by it upon completion of the usual spacing stroke. Specifications 197,354 and 223,866 are referred to.

A vertical annular wall 4 rises from the base 1 of a closed and sealed chamber 3. At the centre of the base is a cup 5 extending from well below the base to nearly the top of the box 2. Sealing liquid is contained between the wall 4 and cup 5. An inverted bell 8 with the edge sealed by the liquid 7 has a centrally arranged transformer core provided with three legs a, b, c. On the middle leg is an insulated winding 10 embedded in insulating material 11 and forming a transformer primary winding one end of which is connected by a conductor 12 to the secondary 13 of a transformer and the other end is grounded at the point 14. The other terminal of the secondary 13 is grounded at the point 15. The cup 5 contains mercury 16. Associated with the secondary winding 13 is a primary winding 17 connected by conductors 18 through an ammeter 20, curvedrawing ammeter 21 and watt-hour meter 22 to a source of alternating current of constant potential. The leading and trailing pipes 25, 26 from a Venturi &c. apparatus lead to the outside and inside of the bell. At no pressure difference in the pipes 25, 26 the core 9 stands with its lower end unsubmerged so that a mercury ring is not formed around the middle leg b. As a pressure difference occurs the bell and core 9 move down forming a ring of mercury around the leg b which causes the readings of the instruments to vary according to the movement of the float. In a modification, the core 9 is arranged to depend from the top of a sealed chamber outside the chamber 3 connected at the bottom by a pipe to the mercury cup 5 and at the top by a pipe to the trailing tube 26.
