Abstract: 1,251,640. Fuel elements. EUROPEAN ATOMIC ENERGY COMMUNITY. 18 Aug., 1970 [22 Aug., 1969], No. 39763/70. Heading G6C. Fuel elements for fast breeder reactors, or experimental or test reactors, are made by first disposing a core of breeder or neutral material in the form of tablets or rods stacked one upon the other to form a column, or in the form of a rod, in a sheath and then introducing fissile material in the form of particles between the core and the sheath by vibration, the maximum particle diameter being approximately equal to the desired distance between the core and the sheath. For breeder reactors, the core may consist of U-238O 2  and for experimental or test reactors a neutral material of high melting point, e.g. magnesia or molybdenum. The vibration gives rise to an excellent radial centring of the core provided the fissile material is of suitable shape. An ideally suited form comprises a powder of PuO 2 -containing pellets (e.g. spheres) of different diameter fractions. The diameter of the largest pellets should be equal to the width of the ring of fissile material subject to a minus tolerance.

Abstract: 1289116 Photo-electric curve followers VSESOJUZNY NAUCHNO-ISSLEDOVATELSKY INSTITUT KRIOGENNOGO MASHINOSTROENIA 7 Oct 1969 49129/69 Heading G1A [Also in Division G4] A photo-electric curve follower comprises a scanning device, fed by reference signals causing a light beam to execute a circular scan over the curve, and respective converter devices for supplying input signals for the X and Y axis step drive apparatus which advance the scanning device along the curve, these signals being dependent on the instantaneous amplitudes of the reference signals when the scanning beam intersects the curve being followed during each scanning cycle. In Fig.1, the scanning device 2 is controlled by reference signals from generator 8 in the form of two 90 degrees phase displaced sinusoidal waveforms. The respective reference waveforms are rectified at 10 and each applied to a device 11. The two instants, during each scanning cycle, at which the scanning beam intersects the line 3 are detected by detector 1 resulting in short timing pulses also being applied to circuit 11. When each of these timing pulses occurs circuit 11 produces an output pulse of a duration dependent on the amplitude of the rectified reference signal at that instant (e.g. by the use of a capacitor which is charged up to a voltage equal to this amplitude and discharged at a constant rate). This output pulse from circuit 11 is applied to gate 12 to allow the output of pulse generator 13 to feed stepping pulses for the step drive 4 or 5. Thus in each circular scanning cycle, the number of steps to be executed along each co-ordinate axis is decided by the output of devices 11. The sign or direction of this movement is decided by the two outputs of each device 15 which produces two 180 degrees displaced rectangular waveforms which are applied to coincidence gates 16, 17 with the output of the detectors. The detector-produced timing pulses produce short output pulses, from the gates one representing positive displacements and the other negative; but one being of much greater amplitude than the other in accordance with the direction of co-ordinate axis movement required. This sign of sequential pulses is recorded in the step drive apparatus and together with the stepping movement acts in moving the scanning device along the curve. The apparatus may be modified to improve precision, by providing a generator with a much higher frequency and corresponding frequency divides between the outputs of gates 12 and step devices 4, 5. The step drives 4 and 5 may also control a machine tool e.g. a gas-cutting machine 9 or the output of converters 6, 7 may control the separate drive members for the tool.

Abstract: 1301475 Screw rotor machines SVENSKA ROTOR MASKINER A B 10 July 1970 [14 July 1969] 35360/69 Heading F1F In a meshing screw rotor machine comprising a housing rotatably mounting at least two intermeshing screw rotors, one at least of said rotors is journalled in bearing assemblies including two axially spaced thrust bearing means, one being of the double-acting type capable of supporting axial loads in either direction and the other supporting axial loads in the same direction as those imparted to the rotor during machine operation with a pre-loaded spring means inserted in series with the said other thrust bearing means to transfer thrust from the rotor to the housing. During operation of screw rotor machines of the kind in which oil is injected into the working space and the female rotor is driven by the male rotor by direct contact between their flanks besides the large axial loads acting on the rotors resulting from the pressure difference of the working medium at the low and high-pressure ends of the machine, axial loads also result from direct contact between the rotor flanks being added to the pressure difference loads in the case of the male rotor and subtracted therefrom in the case of the female rotor. As shown in Fig. 1, the male rotor 28 of a single stage compressor is supported at the high-pressure end of the machine by a double-acting thrust bearing comprising inner and outer ball bearings 34 and at the lower pressure end by a roller bearing 32 and a further thrust bearing 38 whose inner race abuts an axially-slidable sleeve 44 constituting an abutment for a pre-loaded helical spring 46 which at its other end abuts a nut 42 carried by the rotor. When the machine is inoperative, the spring 46 removes axial load from the outer bearing 34. On starting the compressor the spring force has first to be removed before the thrust bearings commence to take axial load. The loading of the spring will determine the load which can be transferred to the bearing 38, any further increase then being taken by the inner bearing 34. The invention may also be applied to a two-stage compressor having additional low-pressure male and female rotors (28A, 30A), Fig. 3 (not shown). The male rotors are in alignment and connected together by a splined coupling comprising elements (62, 64) splined internally and externally and an internally splined coupling sleeve (60). The spring 46 in this case is interposed between the elements (62, 64) and the thrust bearings located at the lowpressure end of the low pressure stage and the high-pressure end of the high-pressure stage. For modifications to the arrangement and disposition of the spring 46 both in single-stage and double-stage compressors reference should be made to the Specification.
