[Also in Division F1] In a steam turbine the steam supplied to the high pressure and intermediate pressure sealing glands 4, 4<SP>1</SP> and 5, 5<SP>1</SP>, is desuperheated before entering the glands by indirect heat exchange with steam which has been cooled to below a desired gland inlet temperature by indirect heat exchange with a cooling fluid of substantially constant temperature. Superheated steam from the turbine boiler or other source is supplied via pipe 9, control valve 10 and throttle valve 11 to a coil 12, where it is desuperheated by cooled steam in the space 18 of the heat exchanger 13, part of the steam then being supplied through an orifice 14 to the glands 4, 4<SP>1</SP> and 5, 5<SP>1</SP> and the remaining passing via pipe 15, coil 16 and pipe 17 to the space 18 of the heat exchanger 13. The steam is cooled in the coil 16 by heat exchange with condensate of steam which is discharged from the low pressure glands 6, 6<SP>1</SP> to a chamber 22 and condensed by coolant flowing through a coil 25. Steam from the space 18 together with steam discharged from the glands 4, 4<SP>1</SP> and 5, 5<SP>1</SP> is desuperheated in coil 21 by heat exchange with the condensate in chamber 22 and then passed to the low pressure glands 6, 6<SP>1</SP>. The chamber 22 is at atmospheric pressure and the level of the condensate therein is limited to 26 by overflow means (not shown). In a modification, Fig. 2 (not shown), superheated steam is supplied directly from the pipe 9 to both the coil 12 and the coil 16 through adjustable orifices. In a further modification, condensate in the chamber 22 is obtained from steam from the turbine valve spindle mechanism which is led into the vapour space 24, the exhaust from the low pressure glands 6, 6<SP>1</SP> being separately condensed. Reference has been directed by the Comptroller to Specification 1,059,917.

Abstract: 1373499 Stranding wire WARNER & SWASEY CO 3 Nov 1971 [14 May 1971] 51050/71 Heading D1T [Also in Division G3] "Dead" or "neutral" steel cord is stranded in apparatus comprising a secondary twister 27 which applies an excess twist to the wires, and a primary twister 25 which permits them to untwist to the neutral condition, the two twisters being driven at speeds maintained in a constant ratio by a control system (Fig. 3) comprising signal generating means 77, 78 responsive to the two speeds # 1  and # 2 , means 90 for selecting the required ratio, means 91 for comparing the two signals and providing an error signal e if the ratio differs from that required, and compensator means 92 for improving the response of the control system at low rates of change of speed ratio, the system being arranged to control the speed of one of the twisters. After passing through a face-plate 38 and a closing die 51 the wires pass round sheaves 47, 46 of the secondary twister 27, which is rotated by a motor 71. The cord then passes around grooved capstan rollers 61', 62 mounted on a flyer 57 constituting the primary twister 25 and via the flyer arm 59 to a take up bobbin 23 which is traversed and driven at a constant speed. Passage of the cord around capstan roller 61', which is geared to the flyer, causes the flyer to rotate, its speed # 1  being indicated to the control system by a tachogenerator 77. A potentiometer 90 (Fig. 3) enables the signal level to be adjusted to produce any desired speed ratio, the output therefrom being compared with that from a tacho-generator 78 driven by the secondary or pretwister 27, the error signal controlling, via an amplifier 93, the pre-twister motor 71. The compensator network 92, (Fig. 5) has component values selected to provide high gain in the loop at low frequencies, without causing instability at high ones. The arrangement is said to control the pre-twister velocity to within 1rpm with a range of primary twister speeds of from 0 to 4,000 rpm.

Abstract: 1,133,300. Controlling reactors. COMMISSARIAT A L'ENERGIE ATOMIQUE. 15 Nov., 1967 [14 Dec., 1966], No. 52022/67. Heading G6C. In a control rod actuator for a nuclear reactor comprising a leak-tight containment vessel which is sealed by a top plug, a rod 1 is disposed inside a stationary liner tube 2 within the seal plug 3 of the reactor and coupled at its upper end to a servomechanism 4 by means of which it may be raised and lowered within the tube 2. The lower end of the rod 1 is fitted with an electromagnet 5 for attaching an assembly 6 which is capable of sliding within a guide tube 7 and a rod 8 which is capable of sliding within the assembly 6. A grappler 9 which engages a control rod 10 is mounted at the bottom of the rod 8. When the control rod 10 is in its lowermost position (as shown in Fig. 1b) the electromagnet 5 is located at the level of the underface of the seal plug 3. The sliding assembly 6 comprises a tube slidable within the liner tube 2 and a spring 11 which is applied against a stopcollar 13 of the rod 8. The guide tube 7 is fixed to a horizontal arm 15 secured to a tube 16 which is located within the seal plug 3 and can be rotated by means of a servomechanism 17. A locking pin 19 also actuated by the servomechanism 17 through the intermediary of a rod 20 within the tube 16 serves to lock the sliding assembly 6 to the guide tube 7 in the bottom position when the electromagnet 5 is not energized. A bellows seal 21 concentric with the rod 1 is fixed at one end to the rod on an annular abutment flange 22 and at the other end to the liner tube 2 on an annular abutment flange 23. A spring 24 concentric with the rod 1 and applied against the flange 22 imparts to the sliding assembly 6 through the intermediary of a movable portion 25, on de-energization of the electromagnet 5, the impulse which is necessary for the rapid dropping of the control rod 10. Opening of the grappler 9 is obtained in the bottom position by de-energizing the electromagnet 5 after having locked the sliding assembly 6 to the tube 7. The rod 8 is then thrust downwards under the action of the spring 11 and the grappler arms separate since they are no longer held by the wall of the tube 6. In order to free the space necessary for the transfer of fuel elements when the sliding assembly 6 has been locked to the tube 7 and the electromagnet 5 de-energized, the arm 15 is rotated through 180 degrees.
