Abstract: 104,662. Bosch Magneto Co., (Assignees of Heins, O.. Wild, C. M., and Wild, J. E.). June 27, 1916, [Convention date]. Connecting-arrangements.-An arrangement for facilitating the meshing of gears, applicable to change-speed or other gearing and described with reference to starting-apparatus for internal-combustion and other engines, comprises a pinion 4, Fig. 1, loosely mounted on a slidable sleeve 5 splined to a shaft 3 and normally pressed against a stop on the sleeve by a spring 16. The ends of the spring abut against or are fastened to the pinion 3 and a member 14 fixed to the sleeve, and the pinion has projecting portions 12 extending into the jaws 13 of the member 14, so that the pinion is capable of a limited rotative and axial movement on the sleeve. If the pinion 4 and gear 1 clash when the sleeve 5 is moved to the left, the spring 16 is compressed until the pinion 4 and member 14 are brought into contact. The compressed spring may then act to slide the bevelled and sharpened ends 19 of the pinion off the teeth of the gear 1 into meshing position and then snap the pinion 4 into engagement, or snap the pinion into engagement after it has been brought into meshing position by a slight rotation of the shaft 3. In modifications, the sleeve is incapable of sliding on the shaft 3, and this shaft is moved to engage the gears, or the pinion is loosely mounted on the shaft and provided with a mutilated hub forming a jaw 27, Fig. 6, adapted to co-operate with the jaw 28 of a member 29 fixed to the shaft, the ends of the spring abutting against the pinion and the flange of a nut 31. Any of the forms may be applied to the shaft of an electric starting-motor in which the armature 40, Fig. 9, is normally held in a magneticallydecentred position by a spring 42, so that, when, by suitable switch arrangements, the shaft 41 is given an axial movement combined with or followed by rotary movement, the pinion 4 is caused to engage the gear 1.

Abstract: 845,668. Particle accelerators. COMMISSARIAT A L'ENERGIE ATOMIQUE. June 11, 1957 [June 13, 1956], No. 18428/57. Class 39(1). [Also in Group XXXV] A magnet for a cyclic accelerator such as a synchrotion has at least one pole-face zones adjacent the air gap which is of lower permeability than the remainder of the pole piece in order to correct for deformations of the field at high values of the induction such as when the magnetic circuit is saturated and possibly also for defects due to the remanent field which occur at low values of the induction. The zones may be formed by providing holes or radial or transverse notches in the pole-pieces or by attaching to the pole-pieces, pieces of different material e.g. a sintered alloy having a base of powdered iron and comprising cells of iron and cells of air. Notches may be provided by juxtaposing metal sheets of alternately different outline and the notches may have different depths. Deformation of the field due to saturation of the whole magnetic circuit may be corrected by tapered zones 20, 21, Fig. 4 ; deformations due to saturation of the polepiece horns 22, 23, 24, 25, Fig. 5, may be corrected by central zones 26, 27 of uniform thickness. Both arrangements may be used in combination resulting e.g. in zones of trapezoidal cross-section. The zones may be subdivided into elementary zones 55, 56, 57, Fig. 14, of different taper to provide a suitable field index at each point. Formulae, graphs and a typical example are given.

Title: Improvements in fuel elements for nuclear reactors
Inventor: AVRAMITO MAURICE
IPC: G21C3/32
Filed: 1959-06-03
Abstract: 920,256. Nuclear reactors. COMMISSARIAT A L'ENERGIE ATOMIQUE. June 3, 1959 [June 5, 1958], No. 19015/59. Class 39 (4). A fuel element for a nuclear reactor comprising fissile material enclosed in a can is characterized in that the cross-sectional perimeter of the can varies, in a continuous or discontinuous manner, along its length in such a manner that the temperature of the can is near the maximum allowable value at all points during operation of the reactor. In Fig. 1, a cylindrical bar 3 of fissile material is enclosed in a cylindrical can provided with radial fins 5, the radial extension of which varies along the length in accordance with a mathematical formula given in the Specification. Two of the pins have a constant radial extension and serve to locate the element in the fuel channel. The fins are thin so the cross-sectional area available for coolant flow is practically constant along the length of the fuel element. Another type of element is shown in cross-section in Fig. 6; the shaded areas a, b are equal so that the crosssectional area of the fuel element, and therefore of the coolant path, is constant along its length whilst the perimeter varies as before. In a modification of this type, Figs. 7 and 8 (not shown), the element is hollow and comprises two cans, of clover-leaf cross-section, with fissile material between them, the thickness of the fissile material varying so that the fissile material is equally distributed along the length of the element. In Fig. 9 the fuel element comprises a number of flat sub-elements arranged in groups which are at right angles to adjacent groups. The number of sub-elements are 3, 4, 5, 6, 5, 4 in the direction of coolant flow; thus the cross-sectional perimeter varies discontinuously and may be equal to the desired theoretical value at the centre of each group. Fig. 10 shows another type of element formed of sub-elements; each sub-element tapers uniformly from a maximum diameter at about two-thirds the way along its length to smaller diameters at each end. In Fig. 11, the fuel element comprises a number of cylindrical subelements, the diameters of which vary so that the perimeters follow approximately the required law; in a modification, Fig. 12 (not shown), the sub-elements are frusto-conical, so that the outer surface of the element as a whole is smooth. The elements may be provided with radial fins to support them in the cooling channel.
