Title: Heterogeneous nuclear reactor of the pressure vessel type
IPC: G21C3/32
Filed: 1965-08-06
Abstract: 1,069,016. Controlling reactors. SIEMENSSCHUCKERTWERKE A.G. Aug. 6, 1965 [Aug. 8, 1964], No. 33893/65. Heading G6C. A heterogeneous nuclear reactor is cooled and moderated by light or heavy water at supercritical thermal conditions to provide automatic control. The water enters the core in two streams, one of which is at a low temperature and is primarily a moderator and the second of which cools the fuel directly. Adjustment of the water temperature by control of the flow, produces large changes in density, at the critical temperature condition. Changes in density are accompanied by changes in the neutron spectrum and hence in the core reactivity. An increase in reactor activity raises the moderator temperature and hence its volume. An increased rate of flow results which is restricted by throttle nozzles. This further raises both the moderator temperature and specific volume and decreases the moderation and reactivity. Each moderator inlet is provided with a nozzle and a radial and axial flux-flattening effect is produced. Further control is provided by the addition of a liquid neutron absorber during start-up and shutdown. In nuclear power plant, the liquid absorber is injected into an auxiliary coolant circuit by-passing the turbines.

Filed: 1961-09-27
Abstract: 956,611. Change-speed gear. FICHTEL & SACHS A.G. Sept. 27, 1961 [Oct. 27, 1960], No. 34751/61. Heading F2D. [Also in Division B7] Change-speed planetary gearing for bicycles &c. is combined with a back-pedalling brake 25 and comprises a driving sprocket 1 slidably engaged by a toothed ratio selecting dog clutch member 3 controlled by the usual chain 20, as shown, the clutch member engaging the ring gear 8 of a simple planetary train, the ring gear carrying ratchet pawls 10 engaging a ring 11 coupled through a positive clutch disc 13 to dogs 15 fast with a driven wheel hub 17. Accordingly, direct drive between the driving sprocket 1 and the wheel hub 17 is obtained. The positive connection between the clutch disc 13 and the dogs 15 has sufficient lost-motion to allow backpedalling for application of the brake 25 to take place without jamming either the ratchet pawls 10 or additional ratchet pawls 26. To establish a high ratio drive, the chain 20 is released so that the ratio selecting dog clutch member 3 moves leftwards into engagement with a planet carrier 4 mounting planet pinions 5 meshing a stationary sun gear 6 and also meshing the ring gear 8. Drive then passesfrom the sprocket 1, through the clutch member 3, the planet carrier 4 and the planet pinions 5, the ring gear 8, the ratchet pawls 10 and their associated ring 11, the clutch disc 13 and the dogs 15 to the wheel hub 17. By pulling the dog clutch member 3 rightwards from the position shown, teeth 23 at its end abut through a thrust ring 24 with the positive clutch disc 13, which is simultaneously slidden rightwards out of engagement with the ratchet ring 11, thus declutched from the wheel hub 17. Drive now passes from the sprocket 1 and the ratio-selecting clutch member 3 to the ring gear 8, the planet pinions 5 and the planet carrier 4, which is disengaged, and thence to pawls 26 mounted upon the carrier, which transmit drive through teeth 19 to the wheel hub 17 at a reduced ratio. In a modified form, Fig. 4 (not shown), the ratio selecting dog member engages slots, instead of teeth, in a sleeve fast with the drive sprocket. Specifications 894,144 and 912,633 are referred to.

Filed: 1961-09-28
Abstract: 990,873. Wire heating furnaces; enamelling wire. COMPAGNIE FRANCAISE THOMSONHOUSTON. Sept. 28, 1961 [Oct. 13, 1960], No. 34911/61. Headings F4B and F4G. In a process of enamelling wire, the latter is passed through a zone in which it is coated with a polymerizable substance dispersed in a volatile carrier, and evaporation and polymerization zones whose atmosphere and temperature conditions are separately and independently controllable. Conditions in the evaporation chamber are controlled such that evaporation is substantially complete and polymerization has begun close to the exit of that chamber. As illustrated, untreated wire passes over a pulley 1 into a preheating chamber 2 and thence over a pulley 5 and through coating means (not shown) into the evaporation chamber 8 and thence over a pulley 10 into the polymerization chamber 11. Repeated passes are made through the chambers 8 and 11 and the wire is finally withdrawn over a pulley 14. Between the chamber the wire may be naturally or force cooled. The evaporation chamber 8 is heated by electrical resistances controlled by temperature probes in the chamber and the volatile constituents freed are drawn off through ducts 15 and 16 and burned in a catalytic block 3. A gas burner, Fig. 8 (not shown), is placed immediately upstream of the catalytic block and is controlled by a probe placed at a point downstream of the block to maintain the temperature at that point constant. Part of the combustion products from the block are passed by a fan 29 to heat the preheating and polymerization chambers, part are passed to the evaporation chamber at M, M<SP>1</SP> and M<SP>111</SP> by a fan 25 (Fig. 7), and the remainder is passed to the atmosphere by a fan 28 together with the exhaust gases from the preheating and polymerization chambers. Shutters 26 and 27 control the proportions passing through these paths and adjustable air inlets are provided on the intake sides of the fans 25 and 29. An air intake 36 on the intake side of fan 28 is equipped with a counterweighted valve to ensure a constant gas outlet pressure. The fans and/or shutters in the gas circulation system may be controlled by the temperature probes in the evaporation chamber. In modifications (not shown), the polymerization chamber may be positioned as an extension of, or at an angle with, the evaporation chamber.

Filed: 1972-07-28
Abstract: 1398992 Automatic position control INTERNATIONAL COMPUTERS Ltd 23 July 1973 [28 July 1972] 35300/72 Heading G3N [Also in Division H2] A speed control arrangement for the driving motor of a paper tractor includes a counter which is set to a value corresponding to the desired paper movement which value is decremented by means responsive to the paper movement and a digital logic arrangement responsive to the counter state to provide selected values of reverse current to the driving motor to bring it to rest at the desired position. In the arrangement described the spacing between the printed lines can be specified as a given binary count, e.g. eight, so that the paper can be moved only for fractions of a line. The required movement is set on counter 14 and as the movement proceeds shaft encoder 20 provides pulses which reduce the residual count in the counter. A control signal for motor drive is provided by a logic circuit 42 responsive to the counter output on lines 22 and to a maximum speed signal on line 44. The motor current is altered by switching into circuit one or more resistors in banks 46, 48 where these resistors preferably are effective to provide binary power changes. The direction of current through the motor is reversed by first switching means to provide braking and the resistor banks selected by second switching means to change the braking effect as the motor approaches the desired position. The arrangement is controlled so that if maximum velocity is not reached the motor supply is reversed after half the movement has occurred but if the maximum velocity is reached the motor supply is reversed to one line space (eight left in counter) from the end of the movement. The control of motor movement is obtained by the various gates and the like associated with counter 14.  In an alternative supply arrangement for the motor only a single set of resistors is used and a changeover switch provided for reversing the motor armature supply, Fig.4 (not shown).
