Abstract: 1,204,554. Rotary-piston hot gas engines. G.G. RUBIN. Aug. 8, 1968 [Aug.10, 1967], No.37964/68. Heading F1F. A rotary-piston hot gas engine comprises two or more trochoidal chambers, a three or moresided piston planetarily rotatable in each chamber, at least one inlet port and at least one outlet port in each chamber, at least one closed loop connecting an outlet port in one chamber with an inlet port in the other or another chamber, and an outlet port in the said other chamber or said another with an inlet port in the said one chamber and heater means in advance of one of the inlet ports. As shown, two chambers 11, 21, Fig. 1, of two-lobed epitrochoidal profile house three-sided pistons which planetary rotate in the same direction, as shown clockwise, an interconnected shafts 13, 23. The chamber 11, a hot chamber is connected by first and second independant closed loops 31,32 to the chamber 21, a cool chamber, having a cooling passage 24 through which a cooling medium such as water flows. In operation, gas, which may be air, hydrogen or helium is admitted to the cool chamber 21 from the first loop 31 through an inlet port 25 and compressed between a piston face and the chamber profile and after compression exhausted through a piston passage 39 and an outlet port 26 into a line 34 including a heater 35, which, e.g., may be gas burners applying heat to coils within the heater, adjacent the hot chamber 11. The hot gas is admitted to the chamber 11 through an inlet port 15 when the volume between a piston face and the chamber profile is a minimum. The expanding gases then drive the piston and exhaust gases from the hot chamber pass through an outlet port 14 into a line 33 connected to the inlet port 25 of the chamber 21. Each piston face in turn in the cold chamber compresses the gas and each piston face in turn in the hot chamber is acted upon by the expanding hot gases. The second loop 32 fitted with a heater 38 and connecting an outlet port 17 from the hot chamber with an inlet port 28 in the cold chamber and an outlet port 27 from the cold chamber with an inlet port 16 in the hot chamber enables the power of the engine be doubled. In a modified embodiment, Fig. 5 each loop includes a heat exchange 42, and an auxiliary cooler 43. On the left hand side of Fig, 5, the hot gases entering the heat exchanger are from the second loop and the cool compressed gases from the first loop and vice versa on the other side.

The moving iron 4 of a moving iron meter rotates with the spindle 6 in the air-gap between a pair of parallel polepieces 3 which act on the edges of the moving iron. Each polepiece has a central cut-out 3<SP>1</SP> providing a non-uniform distribution of field affecting the scale law of the instrument, and by relatively rotating the polepieces the scale law may be adjusted. By incorporating a permanent magnet 8 Fig.13 (not shown) in the field system zero adjustment may also be provided for. The field coil 2 may embrace the iron as shown or as in Fig.11 (not shown) the iron may move between parallel polepieces which extend beyond the periphery of the coil, the extensions having peripheral cut-outs corresponding to the central cut-out of Fig.1 and the iron moving in the space between these cut-outs about a pivot axis coincident with the axis of the coil.

Abstract: 1,129,497. Plutonium oxide; nuclear fuel. UNITED STATES ATOMIC ENERGY COMMISSION. 1 Sept., 1966 [10 Sept., 1965], No. 39182/66. Headings G6C and G6R. A plutonium oxide sol is prepared by mixing a strong base with a nitric acid solution of tetravalent plutonium to precipitate hydrous plutonium oxide, washing the precipitate, dispersing it in nitric acid, heating with agitation at 60-80 C. to form a first sol, evaporating to dryness and heating at below 200 C. to reduce the residual nitrate content to 0À4-1À0 mole per mole of plutonium, and dispersing the resulting solid in water. The sol may be dried in shallow trays to form gel fragments which are fired at 1100- 1150 C. to dense oxide particles suitable for vibratory compaction into nuclear fuel elements. Alternatively, the sol may be passed as droplets into a column containing an organic solvent, e.g. 2-octanol mixed with 2-ethyl-1- hexanol or 2.methyl-1.pentanol, which dehydrates the droplets to yield gel microspheres which are dried and calcined. Urania or thoria sol may be added to the PuO 2  sol to produce mixed oxide fuels.

The tangential air component enters the chamber 17 through tangential inlets 24 and determines the peripheral velocity of the swirl while the radial air component enters by an annular gap formed by an annular shield 21 and a shield plate 22 and determines the axial velocity of the swirl. The swirl angle is controlled by varying the width of the annular gap by moving the shield plate 22 axially, thus altering the ratio of air entering the chamber tangentially and radially. Adjacent the constricted outlet 18, 19 the annular chamber terminates in an annular wall 20 and the gap between the chamber 17, 18, 19, 20 and a burner housing 10 provides a passage for the axial flow of the secondary air. In an alternative embodiment (Fig. 3, not shown) the nozzle assembly 12 and chamber 17-20 are axially movable, the shield plate being fixed to the burner housing 10. In a further embodiment (Fig. 4, not shown) the burner is modified to operate with both liquid and gaseous fuel, either simultaneously or alternately, the wall portion 19 being provided with gas nozzles.
