Title: Fast reactor
IPC: G21D5/08
Filed: 1974-02-04
Abstract: 1442088 Fast reactor plant S B BOBROV V G ILJUNIN I A KUZNETSOV V M MUROGOV J V SILAEV L V TOCHENY and A N SHMELEV 4 Feb 1974 5059/74 Heading G6C A fast reactor core is divided into radial sub-zones in one of which, employing ceramic fuel, coolant temperature is higher than in another which employs metal fuel. In one embodiment (Fig. 1, not shown) a bleeder blanket (3) containing U-238 or Th-232 surrounds a core in which a peripheral sub-zone (1) containing uranium-alloy fuel is cooled by a lower temperature coolant than is an inner sub-zone (2) containing PuO 2 -UO 2  fuel. The relative positions of the sub-zones may be reversed in the radial sense. The higher temperature sub-zone (2) may be of greater vertical height than the other sub-zone (1) and fuel element spacings in the different sub-zones may differ (Figs. 2 and 3, not shown). Coolant, which may flow upwards or downwards through the core may be a liquid metal, e.g. lithium, but helium can be used to cool the higher temperature sub-zone (2). In one arrangement of nuclear power plant (Fig. 8, not shown) coolant passes from the different sub-zones (1,2) by way of respective outlet headers (5,7) to separate external circuits; the lower temperature coolant generates steam in a steam-generator (14) and the steam passes to a superheater (15) heated by the higher temperature coolant. Both coolant flows return to their associated subzones via respective inlet headers (4,6). An insulating interlayer (13) (Fig. 7, not shown) comprising fertile elements may be disposed between the sub-zones (1,2). In another embodiment (Fig. 4, not shown) a single inlet header (10) is common to both subzones (1,2). In nuclear power plant incorporating such an embodiment, (Fig. 10, not shown), coolant from the higher temperature sub-zone (1) passes through a superheater (15) and steam-generator (14) before returning to the common inlet header (10); whereas coolant from the lower temperature sub-zone (1) enters the superheater (15) to mix with the other coolant flow at an intermediate point (19). In a further embodiment (Fig. 5, not shown) a single outlet header (11) is common to both sub-zones (1,2). In nuclear power plant incorporating such an embodiment (Fig. 9, not shown), coolant passes from the common outlet header (11) through both a superheater (15) and steam-generator (14); the normal throughflow output of coolant from the steam-generator (14) is supplied, via an inlet header (4), to the lower temperature sub-zone (1) whereas coolant removed from an intermediate point (18) in the steam-generator (14) is supplied, via an inlet header (6), to the higher temperature sub-zone (2). In another embodiment (Fig. 6, not shown) coolant passes from an inlet header (5) first through the cooler sub-zone (1) to a header (12) and thence through the hotter sub-zone (2) to an outlet header (7).

Apparatus for causing faulty workpieces on a conveyer to be discharged from the conveyer, or marked or otherwise operated on, at a particular point along the length of the conveyer and as the result of a test on the workpieces at a testing station preceding said point, comprises a control device having a base-plate 1 over which is mounted a disc 4 having apertures 5 of which a predetermined successive number are filled with balls 8 from a supply tube 9 each time a workpiece at the testing station gives a response indicating a fault. The disc is driven to move in step with the conveyer so that when the faulty workpiece arrives at the discharge or operating station the balls in the apertures 5 reach an actuating arm 13 of a micro-switch adapted to switch on the discharge &c. mechanism and maintain it actuated for a time depending upon the number of successive apertures 5 filled with balls. The position of the micro-switch is made adjustable to correspond with different discharge or operating positions along the conveyer by mounting it on an arm 15 pivoted on the axis 2 of the disc, the arm being clamped in a desired position of adjustment by a screw 17 engaging an arcuate rail 16. After passing the arm 13 the balls remain in the apertures 5 until they reach an opening in the base-plate 1 through which they are ejected by a spring 19 to return to the tube 9. The balls are released from tube 9 by the retraction of a pin 10, Fig. 4, which is effected by a solenoid 11 energized through a relay 24, Fig. 5. The relay is energized for a predetermined time by an arrangement comprising an A.C. circuit completed temporarily by the testing means, a rectifier 21, condenser 22 and bleed resistor 23, the latter being adjustable to vary the length of time relay 24 remains energized after the A.C. circuit is broken.

Title: Improved Stop Motion for Machines for Treating Textile Fabrics with Liquids.
Inventor: WOOD FRED
IPC: D06B23/00
Filed: 1918-03-26
Abstract: 123,626. Wood, F., and France, T. March 26, 1918. Stop-motions.-In washing, scouring, and like machines for treating fabrics with liquids, combined means are provided as described below for stopping the machine if the drafts of fabrics fail to pass through the respective openings in the usual guide frame, or if the fabric wraps around one of the nipping-rollers, or if the belt transmitting motion to the usual draw roller breaks or fails. Outside each side frame a, Fig. 1, of the machine, a hand-lever j is secured to a crossshaft i, and one lever j is providedl with a finger l, depending into position to engage a hook m<1>, Fig. 2, on a slide m, which is mounted on a fixed guide n and has a. rack surface o in gear with a pinion o<1> on the shaft o<2>. A weight p, secured to a cord wrapped around a pulley p' on the shaft o<2>, tends to rotate the pinion o' and force the slide m outwards to cause guides q on the slide to move the driving-belt from the fast pulley d to the loose pulley c, to stop the machine. This action takes place if one of the levers j is raised to cause the finger l to free the hook m<1>, and the slide m is restored to the driving position by a handle r on the shaft o<2>. The usual guide frame e has a lever t secured to its pivot pin s, and the lever t is connected by a chain t<1> or a link to a counterweighted lever u, so that, when the frame c is raised, the free end of the lever u acts on the lever to raise it and stop the machine. If the fabric wraps around the nipping-roller g, this is raised and one or both bearing-blocks w of the roller shaft or the shaft end.s act on depending arms v on the levers j to raise them. If the belt driving the draw roller h breaks, the fabric is prevented by a rail z<1> from being carried over the roller g and drops on a pivoted board z, which is tilted thereby and acts through a lever and link to raise the lever j on the opposite side of the machine. In modifications, a bar extending over the roller g and connected to the levers j is used to stop the machine when the roller g is raised, the rail z<1> being dispensed with if desired, and a pulley carried by a lever and engaging the belt driving the draw roller is used to raise the lever j if the belt breaks.
