Title: Rolling mill stand
IPC: B21B39/16
Filed: 1974-10-17
Abstract: 1443864 Rolling mills K NEUMANN 17 Oct 1974 [26 Oct 1973] 44982/74 Heading B3M A rolling mill stand (Fig. 1) having rolls 14 and 15 supported in the windows of housings 1 and 2, is provided with a pivotal mounting 26 for the housing 1 to enable it to be pivoted away from the stand (Fig. 2) to allow axial removal of the rolls. The stand may accommodate vertical rolls 18 and 19 which are guided within cross beams 2c and 2d. Before the housing 1 is pivoted, therefore, it is uncoupled from an extension 4 of the housing 2 (using a bolt 6) and from the beams 2c and 2d (by hydraulically withdrawable bolts). The horizontal and vertical rolls are supported as a unit on liftable rails 33 before the housing is pivoted, and can then be rolled on to the aligned rails 52 of a carriage which can move parallel to the rolling line. The carriage, and is supporting rails 55, 56 are moved clear of the housing 1 before it is lowered. Entry guides (Fig. 4, not shown) are pivotally mounted on the chocks of the vertical rolls for removal together with the roll assembly. The guides are secured to the beams 2c and 2d following roll.changing operations and are then independent of screwdown movement of the vertical rolls.

Abstract: 1,073,537. Steering gear. C. C. JENSEN. Nov. 6, 1964 [Nov. 6, 1963 (2)], No. 45428/64. Heading B7V. [Also in Division F1] An hydraulic steering plant for ships comprises a hand pump (1), Fig. 1 (not shown), which can deliver pressure liquid through a valve (23) to an hydraulic steering mechanism including an annular member (47) in a continuously rotating rudder pump (35), a return pump (36) utilizing the same annular member for returning the valve (23) to its neutral position and an auxiliary pump (37) which rotates together with the rudder pump and the return pump, the annular member (49) of the auxiliary pump being mechanically connected to separate steering means through solenoid (62). The auxiliary pump is used for automatic steering as the solenoid receives electrical impulses from an automatic steering apparatus of known type (not shown). Hand steering may also be established automatically on rotation of the hand pump if the power-driven rudder, return and auxiliary pumps fail. If the hand pump does not function and the electric automatic steering devices fail, the annular member (49) of the auxiliary pump can be moved by hand lever (63) for the auxiliary pump to bring movement of the rudder through the rudder pump.

Title: Apparatus for the storage and liberation of energy
IPC: H03K3/38
Filed: 1971-09-30
Abstract: 1336359 Superconducting pulse generators COMPAGNIE GENERALE D'ELECTRICITE 30 Sept 1971 [1 Oct 1970] 45684/71 Heading H3B [Also in Division H2] A superconducting device for generating a short rise time pulse has a superconducting coil 1 and a non superconducting winding 3 which together form a transformer; each winding may have its ends connected by a respective switch 2, 5, and an external load 6 is connected to the secondary winding 3. A persistent current is established in the coil 1 by passing a current through it and then closing switch 2. To release the stored energy switch 2 is opened at instant t1, Fig. 2. The resulting voltage across the coil is shown as U1, it being essential that the switch 2 opens relatively slowly to avoid this voltage being too large. The switch 5 remains closed during this operation, and a current I21 builds up in the secondary as the coil current Il drops. At instant t2, which is about 200 Ásecs. after t1, switch 5 is rapidly opened and I21 drops to zero while the load current I22 rises sharply. The switch 2 may be a conventional circuit breaker having an arc which is blown out pneumatically, or may be a superconducting switch controlled by a low power slowly rising pulse. The switch 5 may be an explosive action device where a hammer strikes a notched bar, or may be a superconducting switch controlled by a high power sharply rising pulse.

Capacitor C forms with inductor L1 a tuned circuit in the collector circuit of transistor T1 whose emitter load consists of a resistor R1 and H.F. choke L2. Feedback is provided through a capacitor C2. A signal whose frequency is determined by C is radiated by aerial A extending through a hole in ring 3. A receiver consists of a conventional f.m. radio receiver without automatic frequency control of its local oscillator. Its output is fed to the Y-plate of an oscilloscope and the spot is continuously recorded on a film moving in the X-direction. A valve voltmeter may give a numerical indication. Short or open circuits may be detected by connecting a current indicator in place of fuse F.
