Title: Low capacity nuclear reactor and fuel elements therefor
IPC: G21C3/28
Filed: 1970-12-09
Abstract: 1281979 Fuel elements BROWN BOVERI/ KRUPP REAKTORBAU GmbH 9 Dec 1970 [16 Dec 1969] 58551/70 Heading G6C A fuel element for a low capacity nuclear reactor consists of a moulded plastics body acting as a moderator and particles of fissile material contained within the body, each of the particles having a gas-tight envelope, and the particles deing distributed in the moulded plastics body in such a manner that zones of predetermined densities of fissile material are established, whereby an inhomogeneous distribution of fissile material is created in the fuel element. The coated fuel particles may be embedded in the moulded plastics body, contained loosely in cavities in the body, or contained in the cavities in the form of bonded particles. The diameter of the particles is typically 0À5 mm. and the thickness of the gas-tight envelopes 0À3 mm. Polyethylene is a particularly suitable plastics material because of its high thermal conductivity. In the reactor shown in Fig. 5, plate-like fuel elements 1 are provided with the fuel particles forming a layer in each element. The elements 1 are fixed relatively to each other by means of pins inserted in complementary holes 4. Each element 1 contains appropriate holes constituting absorber-rod passages 5, cooling passages 6 and one or more irradiating passages 7. The heat generated in the fuel elements 1 can be conducted to the container wall 8 by way of the moderator and a heatexchanging medium, e.g. water, contained in the cooling passages 6 or other gaps between the fuel elements and dissipated by means of a coolant circulating through cavities 10 in the wall 8. For higher reactor capacities, however, it may be advantageous to cool the reactor core direct by means of a coolant circulating in the above-mentioned passages 6. The gaseous or liquid coolant is fed to and from the passages 6 via ports 11 and chambers 12, flow restrictors 13 being provided in the upper and lower coverplates 14 of the reactor container. In an alternative arrangement (Fig. 3, not shown), the fuel particles are not distributed over a layer but are contained in uniformly disposed cylindrical cavities, the axes of which are at right angles to the planes of the plate-like elements 1. In a further embodiment (Figs. 6 and 7, not shown), the fuel particles are accommodated in the hollow interiors of rod-like or spherical fuel elements. In the case of the rod-like fuel elements, the ends of the elements are tapered to enable the elements to be centered in conical recesses in the two cover-plates of the reactor container. The particles used in the abovedescribed fuel elements may conveniently have a core of UC (20% enriched U) and a coating of pyrolytic carbon.

Title: Peak detector
IPC: G11B15/44
Filed: 1973-12-21
Abstract: 1429728 Measuring peak values of voltages SONY CORP 21 Dec 1973 [26 Dec 1972] 59459/73 Heading G1U A peak detector circuit comprises two rectifiers having different time constants, that with the longer being connected to an attenuated version of the input and also a uni-directionally conductive device connecting the two and able to conduct charge from the one with the longer time constant to the other when the voltage across the former is greater than that across the latter. As described the braking control in a tape recorder includes  means for providing a sawtooth waveform whose amplitude indicates tape speed (3-7) Fig. 1 (not shown). The shorter time constant circuit 25 has a load resistor so that the voltage across it V c  is a triangular waveform Fig. 2F (not shown). Its minimum voltage however is normally above the normally detected output Vb from the second rectifier 29, thus transistor 33 is normally reversebiased and the output Se follows the rectifier 31 output. If the tape speed increases suddenly, the sawtooth input falls in amplitude, the voltage V c  rapidly decays to its new level and in so doing forward biases the base-collector junction of tran-  sistor 33, dragging Vb down also. Thus the brake current can be controlled to follow rapid changes in tape speed while avoiding ripple.

Abstract: 668,411. Magnetic device for measuring thickness. BRITISH IRON & STEEL RESEARCH ASSOCIATION. July 14, 1950 [July 15, 1949], No. 18703/49. Class 37. A device for measuring the thickness of a magnetic body of which only one face is accessible comprises an electromagnet 16 with pole faces 19, 20 which can be brought into contact with a surface of the body to produce a saturation flux therein, the flux circuit having a narrow non-magnetic gap 22 across which is a further magnetic circuit comprising pole faces 24 in which is an energized moving coil 23. The flux developed across the gap 24, 24 varies inversely with the thickness of the plate bridging 19, 20 so that the moving coil 23 is deflected in relation to the thickness. The flux passing from pole 16 to pole 19 comprises the flux through the plate under test together with the air or stray flux; this latter flux varies with the current .through the coil 17 and its effect is eliminated by a winding 27 on the shunt circuit including the moving-coil gap, so that the coil deflection is dependent only on the thickness of the plate.
