In a nuclear reactor of the type described in Specification 1,069,016, the fuel elements 2, 3 are arranged within tubes 4 and 4<SP>1</SP> respectively so as to permit the flow of coolant moderator water along both the inner and outer tube surfaces. Water, at supercritical pressure, enters at 11 and 12, one part of which, 21, flows downwards between 4 and 4<SP>1</SP> and outwards through apertures 141 and 151 to form a mixture with the second part, 22, which passes through the apertures 142 and flows upwards over fuel 2, where evaporation occurs. The coolant passes through apertures 152 and flows downwards over the superheating fuel 3 in the tubes 4<SP>1</SP>. To reduce heat losses to the moderator water, the tubes 4<SP>1</SP> are thermally insulated. Each fuel element comprising a metal box structure containing tubes in which the fuel rods are loosely supported. The upper end of each tube is fixed at its upper end, the lower end being free to permit thermal expansion. The lower end of the metal box structure also has a bellows mounting to permit displacements.

Abstract: 1,042,939. Heat-treating rails. UNITED STATES STEEL CORPORATION. Sept. 23, 1963 [Oct. 12, 1962], No. 37341/63. Heading C7N. A railroad rail 14 is heat treated by bending it in the plane of the web of the rail within the elastic limit so that the rail head is convex and the rail flange concave (see Fig. 2), continuously heating the rail head progressively from one end to the other above the austenitizing temperature e.g. to 2000‹F. using an induction heater 37, initially quenching the rail head surface progressively, e.g. using air jets from a head 45, to cause the austenite on the surface to transform to pearlite, allowing self tempering of the quenched surface e.g. to 1250‹F.by absorption of the head's internal heat, finally quenching to ambient temperature e.g. using water jets from a head 46 and releasing the rail from bending stress to permit it to straighten. For preparing a rail 14 for heat treatment, it may be positioned on spaced blocks 26 provided on an elongated carriage 10 adapted for travel longitudinally on ways 12, the blocks having a height defining the curvature of the rail flange when bent e.g. by jacks 29 engaging the rail ends and operated by pistons and cylinders 36; the bent rail may be held to the carriage by releasable jaws 27 attached thereto. The carriage with bent rail clamped thereto may then be driven by a car 19 past an induction heater 37 mounted adjacent the carriage path, means being provided for causing up and down movement and tilting of the heater during carriage travel to have the heater follow the arcuate form of the head. The quenching heads 45 and 46 are preferably similarly arranged trailing the heater. The final structure of the rail head is pearlitic but may include up to 10% procutectoid ferrite and up to 25% bainite.

Jib cranes.-The jib a is supported at two points e, f on inclined or curved guides c, d, and the hoisting rope k is led from a drum j' on the frame direct to a guide sheave f on the rear of the jib and thence to the head sheave g so that the load moves horizontally in luffing. In a modification, Fig. 5 (not shown), inclined or curved guides on the jib engage fixed points of support; in two other modifications, Fig. 7, and Fig. 6 (not shown), one point e of the jib is supported on an inclined or curved guide and another point h is supported by the end of a radius link x. The jib may be mounted on road, rail or other chassis, forming a unit with low centre of gravity and requiring little head room. As shown, luffing is effected by ropes n attached to the jib at e and passing round guide sheaves at l and grooved barrels m operated by spur and non-reversing worm gear. In those forms of construction in which the point e moves in a curved path, the barrels m are of fusee type. In the construction shown in Fig. 7, the luffing ropes pass round fusee drums m, the ends of each rope being attached to the jib at e and h. Screw or other gearing may be used for luffing.

Title: Improvements in or relating to forming spherical particles
IPC: B01J2/06
Filed: 1956-12-14
Abstract: Solidifiable liquids are formed into spherical drops by maintaining a chamber 10 filled with the liquid, introduced at 13, under a suitable pressure and subjecting the liquid to periodic impulses by means of a diaphragm 11 and a vibrator 15 whereby the liquid streams issuing from orifices 12 in the base of the chamber become broken into drops or corrugated and ultimately broken into drops of uniform size.  A vent 16 is provided to remove any trapped gas or vapour from the chamber.  In examples, gelable alumina hydrosols were comminuted (a) by passing at the rate of 190 c.c. per minute through each orifice of diameter 3.175 mm. while being subjected to pulsations of frequency 55 c.p.s.; (b) by passing at the rate of <PICT:0813146/III/1> 99 c.c. per minute through each orifice of diameter 1.588 mm. while being subjected to pulsations of 150 c.p.s.  The particles passed into hot oil at 93 DEG  C. and after setting, ageing, washing and drying had diameters of 3.175 mm. and 1.588 mm. respectively. The process is compared with a prior process in which the discharge orifices (in the form of dropping tips) are vibrated instead of pulsations being applied to the liquid.
