Title: Manufacture of uranium fluoride
Inventor: DELANGE MAURICE
IPC: C01G43/06
Filed: 1961-04-04
Abstract: <PICT:0970994/C1/1> In a continuous method for producing uranium fluoride, uranium dioxide granules are fed through a vertical conduit leading directly into a fluorinating furnace in a countercurrent direction to a stream of hydrofluoric acid gas which is fed to said furnace in excess, and the residual gas leaving the fluorinating furnace is absorbed by uranium dioxide granules in said conduit.  In the preferred embodiment uranium trioxide or a mixture of uranium di- and trioxides are passed through a reducing furnace to obtain the uranium dioxide granules which are then passed directly through said conduit into the fluorinating furnace where preferably 10 to 30 mol. % excess hydrofluoric acid gas is used. The conduit is preferably of a wider cross-section at the bottom than at the top. In the Figure a UO2-UO3 mass is introduced via 2 into furnace A, which is heated at 6, and the UO3 is reduced by a reducing gas, e.g. H2 and/or NH3, introduced at 1.  The UO2 produced is fed via flared conduit 9, which preferably has a cooling jacket 10, to furnaces B and C where the oxide is fluorinated to produce UF4.  Heating means 7 and cooling means such as fins 8 are provided to maintain furnace B at 400 DEG to 500 DEG  C., and furnace C is kept at 500 DEG  to 600 DEG  C.  The excess HF is absorbed by the UO2 in conduit 9, the conduit preferably being cooled to 200 DEG  to 300 DEG  C.  Specifications 800,692 and 855,217 are referred to.

Title: Improved electrical protective relay
IPC: H02H3/40
Filed: 1924-05-24
Abstract: 216,531. Metropolitan-Vickers Electrical Co., Ltd., (Assignees of Crichton, L. N.). May 26, 1923, [Convention date]. Cut-out systems; induction relays. - In protective arrangements for isolating a faulty portion of a system divided into a number of sections by substations, self-grading relays operated by a current and restrained by a voltage coil are employed for tripping the circuit-breakers, so designed that they close in a time which varies inversely as the current and directly as the voltage and, consequently, bring out the circuitbreakers nearest to the fault. In the construction shown in Figs. 2 and 4 in which induction-type relays are employed, the current coil 4 causes rotation of the induction disc 11 in the anticlockwise direction and winds up, directly or through gearing, a spiral spring 25 the other end of which is connected to an arm 24 and tends to drive a lever 8 into a position where it forces together the relay contacts 6. The movement of the lever 8 is restrained by the easily saturated core 21 of the voltage coil 17. The core carries a cage 31, Fig. 4, with a jewelled bearing 32. A steel pin 33 on the pivoted lever 8 engages with the bearing, and, in order to close the relay contacts the inductive disc has to be rotated to such a position that the torque of the spiral acting through the arm 24 is sufficient between the bearing point and the pivot 23. In the case of a heavy fault near the relay, the voltage falls off practically to zero and a very small movement occupying very little time is adequate to develop sufficient torque to operate the relay. In the case of more remote faults, the voltage coil exerts some restraining action and the time element is greater. In order to adapt the arrangement to the protection of portions of a ring main where not only the distance of the fault must be taken into account but also the direction in which energy is flowing with regard to the fault, the contacts of relays as described are connected in series with those of ordinary reverse current relays so that the graded relay does not close the tripping circuit except when the energy flow to the fault is in a predetermined direction.

Heading D1S [Also in Division F2] Each of a series of articles coming from an ironer 1 is folded by a blade 3 between rollers 4 about a line which divides its length in a predetermined ratio irrespective of the length of the article. The article passes from the inner into a nip formed by a conveyer 2 moving at a constant speed and a length measuring roller 7; roller 7 drives, through intermediate gears 9 a gear wheel 8 which can drive a cam 10 through an electromagnetic clutch 11, the transmission ratio being determined by the intermediate gears 9 but in this case being such that cam 10, when clutch 11 is engaged, moves through a peripheral distance equal to half the length of article passing under roller 7. Cam 10 is alternatively driven through an electromagnetic clutch 13, by a motor 12 which has a constant speed such as to give cam 10 a peripheral speed equal to the speed of conveyer 2. In operation, a photo-electric switch 15 is actuated by the leading edge of the article as it moves under roller 7 which in turn causes clutch 11 to be engaged so that cam 10 is rotated by roller 7 (motor 12 also being started by means of a micro-switch 14). Cam 10 is rotated by roller 7 until the trailing edge of the article passes the photo-electric switch 15 which then disengages clutch 11 and engages clutch 13 for cam 10 to be driven by motor 12. The cam then continues to be rotated until it has performed one revolution at which moment the centre point of the article (whatever its length) has reached a point X, a fixed distance from roller 7; micro-switch 14 is simultaneously operated by cam 10,this time to stop motor 12 and actuate a time delay relay which has a time lag such that the centre point of the article moves from the point X to be level with rollers 4 before the relay operates and causes an air actuated folder knife 3 to push the article between the rollers 4 and cause it to be folded about its middle point; the folded article is then carried away by a conveyor 6 which may lead to a stacking, device, a deliver table or a further folding mechanism. The article may be folded in any other ratio by suitable selection of the transmission ratio between roller 7 and cam 10. More than one device may be provided together with an automatic cycling switch so that successive articles from the ironer are dealt with by different devices to further forms micro-switch 14 is replaced by a photo-electric switch and intermediate gearing 9 is replaced either by a pulley system or by arranging roller 7 to drive a tacho-generator which feeds, through a pulse shaping and amplifying circuit, a synchronous motor driving cam 10, the motor being alternatively driven by pulses from a tacho-generator driven by the conveyor 2.
