Title: Improvements in or relating to nuclear reactor moderators
IPC: G21C1/12
Filed: 1960-12-01
Abstract: 913,887. Moderator structures. SOC. NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION. Dec. 1, 1960 [Dec. 4, 1959], No. 41381/60. Class 39 (4). A moderator structure for use in a high temperature nuclear reactor subjected to accelerations and to substantial inclinations to the vertical, e.g. a nuclear reactor used as the energy source for the propulsion of an aircraft, comprises an assembly of mutually independent moderator columns capable of expanding laterally by reason of clearances provided between adjacent columns and axially by reason of resilient guide means which also provide axial compression for giving mechanical cohesion to each column. In the embodiment shown, the columns comprise superposed elements 10, e.g. of beryllia, connected to each other by means of lugs 27. A tubular terminal member 13 at the upper end of each column embraces a sleeve 14 secured to the cover 2 of the reactor casing 1 while at the lower end of each column a terminal member 11 rests upon a support 12 secured to the lower part of the casing 1. The elements 10 in each column are pressed together by means of a helical spring 24 which abuts a shoulder 26 on the sleeve 14 to one end and a shoulder 25 on the member 13 at the other end. Longitudinal expansion is permitted by the members 13 sliding on the sleeves 14 and laterial expansion by the clearance 23 between adjacent columns. Coolant gas under pressure at a temperature around 350‹ C. enters the casing 1 through the inlet 5 and leaves at a temperature around 800‹ C. from the outlet 6, a deformable wall 7 separating the inlet zone from the outlet zone. Axial channels 15 are formed partly by central apertures in the elements 10, in which are housed fuel elements 20, and partly by bores 16 in the supports 12, bores 17 in the members 11, bores 18 in the members 13 and the bores 19 of the sleeves 14. Coolant gas enters the channels 15 through apertures 21 and leaves through apertures 22. The cover 2 is cooled by circulation of water by way of pipes 3, 4 and the casing 1 by immersion in protective water for the reactor.

IPC: B01J2/02
Filed: 1966-09-20
Abstract: Granulated glass powder, the particles of which are regular in shape and which flow readily, is manufactured by preparing a suspension of glass powder in a solution of an organic binder in a solvent, then atomising the suspension with the aid of air, nitrogen, or other non-inflammable non-corrosive gas, and collecting the granules, wherein the conditions of trajectory which the atomized suspension describes and the atmosphere in which the trajectory is described are such that the solvent evaporates almost completely, so that the granules do not stick together.  The granulated glass powder is used for making glass objects by compression in a mould.  The composition of a glass suitable for use in the process is given.ALSO:A method of manufacturing granulated glass powder comprising the steps of preparing a suspension of glass powder in a solvent, in which an organic binder is also dissolved, then atomising the suspension with the aid of air nitrogen or other non-inflammable non- corrosive gas, and collecting the granules, wherein the conditions of trajectory which the atomised suspension describes, and the atmosphere in which the trajectory is described are such that the solvent evaporates almost completely so that the granules do not stick together. Suitable solvents mentioned are acetone, methyl alcohol and water.  A 40% solution of the polymethacrylates of monobutyl glycol ether in xylene is used as an organic binder.  The mean size of the granules may be controlled to some extent by varying the speed of supply of the suspension and/or the velocity of the air flow used for effecting atomisation.  The liquid in which the powdered glass is suspended also has an effect on the granule size.

Filed: 1974-09-30
Abstract: 1458687 Automatic control of position DORNIER GmbH 30 Sept 1974 42364/74 Heading G3R [Also in Division H3] A vertical axis (centrifuge) rotor is kept in position by a PD controller in response to phase displaced signals from two horizontal deviation sensors. The signals are analogue voltages applied to terminals al, bl of the circuit shown, whose output at a4, b4 energizes correspondingly placed electromagnets. The circuits are designed to provide damping of "circular" vibrations which occur both in the direction of rotation and in the opposite direction, and to filter out components in the sensor signals caused by the rotational axis not being truly coincident with the geometric axis. The latter is achieved in Section F, termed a "circular filter". 4a, 4b are operational amplifiers which receive the respective signals through resistors R1a, R1b and also cross-coupled signals via capacitors C1a, C1b whose reactance (when the rotor is at rated speed) equals the corresponding resistance. U1 is an inverter. The section KO is to improve the damping of vibrations in the direction of rotation; it features low-pass filters R3, C3, R4 for the direct signals and high pass filters C4, R6 for the crosscoupled signals. The section Kr is to improve damping in the opposite direction and also provides the PD characteristic. The input resistors R10 for the cross-coupled signals are a multiple of those, R9, for the direct signals.

Patent GB-425130-A (GB)
Abstract: 425,130. Calculating - machines. ANKER-WERKE AKT.-GES., Bielefeld, Germany. Sept. 11, 1933, No. 25166. Convention date, Jan. 4, 1933. [Class 106 (i)] In a calculating-machine wherein balances are transmitted from a balance totalizer to one secondary totalizer if they are positive and to another secondary totalizer if they are negative, provision is made for locking the machine against operation if the means which selects the secondary totalizer is not set to select the appropriate totalizer corresponding to the sign of the balance. The totalizer to which the balance is to be transmitted is selected by setting a sector 14 into one or other of two totalizer-selecting positions. A sector 41 is pivoted coaxially with the sector 14 and is maintained in the position shown in Fig. 2 when the balance totalizer is in a negative condition and is moved one step anticlockwise when the balance becomes positive. The selecting sector 14 carries a lever 52 having a pin 53 which, if the selecting sector is set to select the correct totalizer corresponding to the sign of the balance, falls into a recess in the sector 41 and allows a lever 16 to engage a tooth on the sector 14 when the shaft 12 is rocked clockwise, Fig. 2, to start the machine. If an attempt is made to select the totalizer which does not correspond to the sign of the balance, the pin 53 rides on the top of the sector 41 and the lever 52 blocks the lever 16, the shaft 12 thus being locked against clockwise movement. The sector 14 is rocked, when the highest numeral wheel passes through the 0-9 interval, by an arm 32 and connections 36, 37, 39. When the starting key 1 is pressed inwards the shaft 12, if free, is first rocked anticlockwise, Fig. 1, by a projection 7 engaging a pin 9 on a lever 11 secured to the shaft, but when the pin escapes past the projection the shaft is rocked clockwise by a spring 66 acting on a link 63 pivoted to the lever 11. The shaft 12 and the key 1 are restored at the end of the operation by a cam 62 acting on the link 63.
