Title: Device for the control of a nuclear reactor
IPC: F16D55/00
Filed: 1974-02-19
Abstract: 1427691 Controlling nuclear reactors INTERATOM INTERNATIONALE ATOMREAKTORBAU GmbH 11 April 1974 [11 April 1973] 16383/74 Heading G6C A control device for a nuclear reactor comprises normally-engaged gear members which can be separated to permit free fall of a control rod, separation being effected by means of a movable actuating element having a profiled portion. As shown, a shaft 19, connected at its lower end to a control rod, affords an axially movable rack 20 engaged by a pinion 30, the latter being driven by a spur gear 29 on a common shaft with bevel gear 28. The latter is driven by bevel gear 27 and spur gears 26, 25 the latter being mounted on a rotatable drive tube 18. The gears 26-30 are mounted on a lever 31 whose pivot axis coincides with the axis of the aforesaid common shaft. The lever 31 mounts a roller 32 urged against a profiled portion 37 of an axially movable actuating element 38 by an auxiliary lever 33 also having a roller 35 bearing on the profiled portion 37. (In a modification, Fig. 9, not shown, the auxiliary lever 33 is omitted and a spring (49) urges the roller 32 against the profiled portion 37.) Thus, when the actuating element 38 is moved axially downwards from the position shown, the pinion 30 disengages from the rack 20 and the control rod falls. The lower end of shaft 19 moves in a housing (45) (Fig. 5, net shown) enclosing helical springs (43, 50) of opposite hand, which impart downward thrust to the shaft when released as above. The shaft 19 is decelerated by means of a damping piston (21) and an assembly (46) of spring washers. A downward tubular extension (22) of shaft 19 is connected to the control rod (4) (Fig. 6, not shown) by means of a claw clutch (23) releasable by axial movement of a rod (51). The actuating element 38 is normally retained in its raised position by an electromagnet (40) (Fig. 3, not shown) and is acted upon by a spring (42) for assisting downward motion when the electromagnet is de-energized. The upper end of the rotatable drive tube 18 is connected to a shaft (16) whose upper end mounts permanent magnets (15) (Fig. 2, not shown). All of the device so far described is sealed from the ambient, in part by a hood (17) which surrounds the magnets (15). Outside the hood (17) are further permanent magnets (14) supported by a cylinder (13) rotatable by a motor (9) (Fig. 1, not shown) via a clutch (10) reduction gear (11) and intermediate shaft (12). Magnetic coupling between the sets of magnets (14, 15) provides for their conjoint rotation.

Title: Improvements in the manufacture of artificial threads and the like
IPC: B65H54/80
Filed: 1934-03-09
Abstract: <PICT:0434881/IV/1> In the manufacture of artificial threads, the thread which leaves the spinning bath under the draft of a galette is allowed to fall freely on to a plate having a rotary and an additional reciprocating movement, or movement with a reciprocating component, so as to form annular crosswise layers, and the ratio of the period of the rotary movement to that of the additional movement is adjusted so that at most only one additional movement occurs at every half revolution, while the period of natural oscillation of the freely hanging thread is adjusted to equality or substantial equality with the period of the additional movement or a harmonic thereof. The thread falls from the galette B on to the plate C which rotates and also has a reciprocating motion, the planetary gear described in Specification 414,991 being employed to drive the plate C if desired. Preferably the additional movement is slower than the rotary movement and the thread is deposited in the form of loops having a curvature which is always concave when viewed from the centre of the cake.  If the additional movement is quicker than the rotary movement the loops appear alternatively concave and convex when viewed from the centre of the cake.  The falling thread has a considerable pendulous movement due to the fact that it is falling on portions of the plate having different velocities as the plate is reciprocated, and the distance a between the galette and the plate is adjusted until the natural period of oscillation of the freely suspended thread, which depends on its weight, the weight of spinning bath adhering to it, and its length, corresponds with the time of one reciprocation of the plate, or until the ratio of the two periods is 1 : 2, 1 : 3 or 1 : 0.5.  The cake thus produced is self supporting and may be washed and after-treated in the same way as a centrifugal cake.  In an example to produce a viscose thread with a titre of 180 deniers from a spinning bath with a specific gravity of 1.4 and a spinning speed of 60 metres/minute, the distances denoted in the figure as a, b, c, d should have the values 725 mm., 95 mm., 80 mm. and 50 mm. respectively.  The dimensions of the cake after 6 hours spinning are given.
