A nuclear reactor comprises a core including a solid moderator supported on a base within a pressure vessel, a thrust ring generally frustoconical in form at the top of the core urging the core against the base, and locating means adapted to keep the core in a predetermined position with respect to the pressure vessel. The core 1 may be constructed of graphite bricks and is constrained circumferentially by a number of steel bands 2. At each end of the core is a conical ring 3 which abuts, through antifriction bearings 4, a conical face on the core itself. Each conical ring carries a number of equally disposed facings 5 on its circumference and, between these facings, a number of vertical keyways 6 which engage with keys 7 secured to the pressure vessel 8 so that the rings 3 are free to slide vertically in the keyways but are held concentric with the pressure vessel. One arm of a bellcrank 9 bears on each facing on the ring 3 and the other arm is connected to a rod 10 which passes through the wall of the pressure vessel and is loaded by a spring 11. The pivot of the bellcrank is held in a bracket fixed to the pressure vessel, and the pivot hole in the bracket is elongated vertically so that the pivot may slide. Attached to the pivot is a tie-rod 14 which is similarly fixed to the bellcrank pivot on the conical ring at the opposite end of the core. The whole core is carried on antifriction bearings 15 supported on a steel framework 16. The construction is suitable for a ship-borne reactor.

Title: Improvements in electric condensers
Filed: 1925-06-16
Abstract: 258,331. Miles, H. A. June 16, 1925. Condensers comprise the combination of two variable units in a casing to form a dual condenser, each unit being of the type consisting of a solid dielectric and a movable plate or plates which may be picked up from or laid down on the surface of the dielectric to vary the capacity, and wherein the pressure may be increased or decreased on one unit to balance its capacity with that of the other. Fig. 1 shows a form of condenser using flat conducting elements 2, 4 separated by insulation 3, the element 2 being secured to the recess 7 in the base 1 and the element 4 being adapted to be laid on, or picked up from, the element 2 by means of a wedge-shaped slot (as 10, Fig. 4), in a disc 5 rotatably, but axially movable on, a spindle 8. The method of moving the plate 4 is substantially as described in Specifications 214,734 and 214,929. In applying the arrangement to simultaneously-operated dual condenser units, according to the invention, the plates 2, 4 are each in two mutually insulated arc-shaped parts and two wedge-shaped slots, as 10, are provided in diametrically-opposite parts of the disc 5. In order to balance the two capacities, a spring arm 6 on an adjustable spindle 14 bears on a spring plate 13 to increase the pressure between one pair of elements 2, 4 proportionally as it decreases that on the other pair. In Fig. 6, the fixed plates 16, 16<1> are disposed about a cylindrical drum 17 and the movable ones 19, 19<1> are disposed over the insulation and pass through slots in a rotatable cylinder 21 on the edge of which bears a spring arm 24 for balancing the capacities. In another form the balancing arrangement comprises a spring-pressed roller applied internally to the cylinder carrying the slots, and in some cases the arrangement may act on only one of the condensers, increasing or decreasing its capacity, as desired, or the differential pressure may be accentuated by suitably shaping the top or bottom of the disc or cylinder. The invention is applicable also to helical or spiral plate type condensers.

[Also in Group XIII] In the making of a heat exchanger tube having fins in the form of a helically arranged continuous or discontinuous series of wire loops 2, the spacing of which may vary around the periphery of the tube, the loops together with a binding wire are fed directly from a mandrel 3 on to the tube as it is rotated. The loops 2 may be secured to the tube surface by soldering, brazing, galvanizing or welding. The feed of the loops to the tube can be interrupted at predetermined points by means of an oscillating fork 5 connected to the cam follower 11 through arms 6 and 9 respectively pivoting at points 7 and 10. As the tube 1 revolves it acts as a cam 11 to lift the fork 5 over the mandrel and prevents the loops from sliding off. In order to apply the loops with varying spacing at different parts of the tube periphery, the rotational speed of the tube is caused to vary during each rotation by suitable gearing employed e.g. elliptical gears (Fig. 5, not shown), a chain drive including a pair of chain wheels one of which is elliptical (Fig. 6, not shown), or a chain drive in which the driving and driven wheels are each mounted eccentrically on their respective shafts (Fig. 7, not shown). In this form the eccentricity of either wheel can be varied at will and need not be equal. Specifications 836,922 and 845,132 are referred to.
