Title: Improvements relating to internal combustion engines of the rotary piston type
Inventor: KAUERTZ EUGEN
IPC: F02B53/00
Filed: 1965-03-15
Abstract: 1,031,626. Rotary-piston internal combustion engines. KAUERTZ (PROPRIETARY) Ltd. March 15, 1965, No. 10937/65. Heading F1F. A rotary-piston I.C. engine comprises two double-wing pistons 11, 12, Fig. 1, rotatably disposed about a common axis with a cylinder 10 with the pistons connected together by a control linkage such that one wing piston executes, in addition to its common rotary movement with the other wing piston, a further relative rotary movement with respect to the latter which cyclically enlarges and reduces the volumes of the chambers between the piston wings. The control linkage comprises a first radial-arm 18 connected by its inner end to a shaft 15 of the wing-piston 11, a second shorter radial arm 19 connected by its inner end to a tubular shaft 16 of the wing-piston 12 and a bell-crank lever 23 fulcrummed on a pin 22 at the end of the first radial arm 18 and whose limbs are pivoted at 25 to a link 26 connected to the end of the second radial arm 19 and at 24 to the outer end of a third radial arm 21 rotatably mounted on an eccentric bearing boss 20 formed on an end wall 17 of the cylinder 10. A balance weight 27 extends from the bearing boss 20 of the third arm 21 to counter balance kinetically the linkage. As the shafts 15, 16 rotate each chamber between adjacent piston wings cyclically increases and decreases in volume to carry out the four phases of suction, compression, expansion and exhaust of a gaseous fuel mixture. Ignition may be by means of a spark-plug or a continually incandescent glowplug. By suitably varying the positions of the ignition means and the inlet and exhaust ports the engine may be arranged to operate on the two-stroke cycle and by suitably increasing the compression ratio it may operate as a compression-ignition engine. To vary the timing of the engine the eccentric bearing boss 20 carrying the third arm is arranged to be arcuately adjusted about an axis eccentric to both the common axis of the shafts 15, 16 and the axis of the bearing boss 20, by means of an adjusting screw 38, Figs. 10 and 11 (not shown) and a toothed segment 37 formed on a disc 33 having a clearance aperture 40 with respect to the shafts 15, 16. To vary the compression ratio the disc 33 may be formed with a spigot 34 insertable in an aperture in a rectangular plate 35 vertically movable between guides 36 by an adjusting screw 43 and nut 44.

A nuclear reactor fuel element comprises a graphite sphere formed at a position spaced from its centre with an internal chamber containing fissile material, e.g. uranium particles coated with pyrolytic graphite, the chamber in the examples described being annular and extending symmetrically around an axis passing through the centre of the sphere. The fuel element (Fig. 1, not shown) may comprise two graphite hemispheres 1, 2 interconnected by a graphite stud 3 formed with two sets of screwthreads, one to each hand. Each hemisphere is formed with an annular recess 11, 2<1> which cooperate to give an annular chamber which receives coated uranium particles 4. An annular graphite closure plug 6 acts as a screen between the uranium particles 4 and the boundary 5 between the two hemispheres. In an alternative embodiment (Fig. 3, not shown), an externally screw-threaded graphite plug 9 is screwed into a blind bore 8 in a graphite sphere 7. The plug 9 is formed with an annular chamber 10 which receives coated uranium particles 4, an annular graphite closure plug 6 being located in the outer end of the chamber 10. The two graphite hemispheres of a further embodiment (Fig. 5, not shown) are interconnected by a screw-threaded stud 13<1> which is an integral part of the hemisphere 11, each hemisphere having a recess which co-operate to form an annular chamber having the shape of a double frusto spherical shell. The hemisphere 11 has an annular step 17 which engages in a mating recess at the edge of the hemisphere 12 in order that no continuous gap may be formed at the boundary between the two hemispheres when the stud 13<1> becomes very hot. The annular plug which acts as a screen between the uranium particles 14 in the annular chamber and the boundary between the two hemispheres 11, 12 may be made of a carbon fibre material, such as felt, fabric, wadding or wool. Alternatively, the annular chamber may be in the shape of two frusto cones the larger diameter ends of which abut one another at a hemispherical plane of the sphere. In either case, the walls of the recesses extend perpendicular to the boundary plane between the two hemispheres, where they meet the boundary plane, to provide a smooth transition between the two parts of the chamber across the boundary plane.

Title: Process for dephosphorizing pig iron
IPC: C21C1/02
Filed: 1962-03-26
Abstract: In the refining of phosphoric pig-iron basic slag-forming materials including lime and iron oxide, and possibly also fluorspar, are added to the bath which is agitated horizontally while a stream of oxygen-rich gas is passed over the bath without penetrating it.  When foaming commences the refining action is moderated by reducing firstly the intensity of agitation and secondly the rate of oxygen supply until the phosphorus content is below 0.1% while the carbon content is above 2%, when refining is stopped and the metal and slag discharged separately.  Where the iron is rich in manganese or silicon these may be largely eliminated in an initial refining step, the slag from which is removed followed by the addition of fresh slag forming materials. The agitation may be brought about in a shaking device of the type described in Specification 801,156, or in a vessel mounted so as to be oscillatable about a horizontal axis.  A suitable slag-forming composition is: lime 25-50 parts, iron oxide 25-50 parts, fluorspar 0-15 parts.
