Title: Improvements in or relating to control rods for nuclear reactors
Inventor: INGRAM DAVID JOHN
IPC: G21C7/11
Filed: 1958-07-08
Abstract: 916,201. Nuclear reactor control rods. GENERAL ELECTRIC CO. Ltd. June 26, 1959 [July 8, 1958], No. 21940/58. Class 39 (4). A control rod for a nuclear reactor comprises a head portion and a body portion of flexible or articulated construction attached to the head portion, the head portion including damped resilient means to absorb the kinetic energy of the rod if it is dropped. Fig. 4 shows the body portion which comprises chain links 12 each of which is clad in two semi-cylindrical members 13 of neutron absorbing material held in position and protected by a stainless-steel cylinder 14. The head portion, Fig. 3, is provided with an energy-absorbing device comprising two coaxial sets of ring springs 17, 18 which, when the rod is dropped for emergency shut-down, dissipate energy by frictional damping between cooperating surfaces on the two sets of springs. A mushroom-shaped portion 15 is normally held by an electromagnet (not shown) the position of which is adjustable for control purposes; in an emergency the current supply to the electromagnet is cut off allowing the control rod to drop until the flange 16 comes up against a guide pin 9. The control rod can be removed by a grab from a servicing machine which engages the mushroom head 15.

Title: Improvements in or relating to telephone message recorders and call answering arrangements
IPC: H04M1/65
Filed: 1952-09-01
Abstract: 732,718. Substation equipment. BAKER, L. G. Dec. 1, 1953 [Sept. 1, 1952], No. 21986/52. Addition to 684,772. Class 40 (4). In an automatic telephone call answering apparatus which in response to the flow of ringing current to the telephone bell actuates the cradle switch for a predetermined period and initiates operation of motor-driven switches to transmit a pre-recorded message and record an incoming message, an inductive pick-up coil is provided for picking up both the ringing signal and subsequent incoming speech signals. Ringing current induced in coil 15 energizes a solenoid 22, after amplification in amplifier 19, and the resulting movement of plunger 23 lifts the handset 12 from its cradle, removes a detent 26 from a radial slot in a circular plate 27 on the end of a cam-shaft 28, and operates a microswitch 30 to start the motor 29. Detent arm 26 rides on the outer surface of plate 27 to maintain the handset in its lifted position when the ringing current ceases. A tape reproducer 50 also driven by motor 29 and carrying the prerecorded message is coupled to the drive through a friction clutch 54 and the reproducer output, amplified in amplifier 66, is applied acoustically to the telephone transmitter by a loud-speaker 79. At the end of the time allotted to the message transmission, micro-switch 57 disconnects the reproducer head and the tape drive is interrupted. Incoming speech currents induced in pick-up coil 15 are applied to the amplifier 66 over a change-over switch 17 and the amplifier output is fed to a recorder 60 by a switch 75. The mechanism is switched off after a complete revolution of plate 27 when the arm 26 falls back into the radial slot. Play-back means for the recorded messages may be manually controlled as described in Specification 684,772. An eraser head 61 which precedes the recording head is fed by an oscillator 64.

In an example a waterproofing emulsion is prepared from ceresin wax, paraffin wax, glue, aluminium hydroxide and acetic acid. To this emulsion a solution of ammonium sulphamate is added; and the emulsion so formed used to impregnate a rayon-cotton fabric.

Title: Improvements in supersonic compressors
Inventor: BOURQUARD FERNARD
IPC: F04D21/00
Filed: 1959-07-02
Abstract: 920,260. Centrifugal land axial - flow compressors. COMMISSARIAT A L'ENERGIE ATOMIQUE. July 2, 1959 [July 7, 1958], No. 22802/59. Class 110 (1). In a supersonic compressor in which the velocity of flow through a blade passage is reduced to a subsonic value by means of a normal shock wave, the passage so shaped upstream of the shock wave as to produce a succession of expansion waves producing an acceleration upstream of the normal shock wave. This stabilizes the position of the shock wave. In the axial-flow compressor shown in Fig. 1, the velocity V a  at the exit from the guide blades 1 may be Mach 0.7, the rotor peripheral velocity U is Mach 1.2, and the relative velocity V r  at entry to the rotor blades 2 is Mach 1.6. The initial portion AB of the suction face of each blade 2 is substantially straight and parallel to V r . The following portion BC is slightly convex, preferably with constant curvature, the tangent at B making an angle of about 7 degrees with that at C. The end C preferably occurs at the termination of a shock wave A‹C starting from the leading edge A ‹ of the following blade 2. The portion CD is straight, and the portion DF beyond the normal compressive shock wave D‹ may be a continuation of CD or may be curved. The pressure face I may be substantially straight. Expansion waves, such as d 1 , d 2 , d 3  occur at the curved region BE, and accelerate the flow upstream of the normal shock wave D‹, producing a non-uniformity of flow velocity which causes the shock wave D‹ to be convex towards the downstream direction. This convexity is stated to assist the stabilization of the shock wave D ‹. Any displacement of the shock wave D ‹ produced by an alteration in the flow velocity causes a variation in the suction exerted on the shock wave by the expansion waves in the sense opposing the displacement, thereby stabilising the new position of the shock wave. The flow is subsonic downstream of the shock wave D‹. The pressure face I may have an initial curved portion, this portion and the portion BC of the suction face then each being curved through an angle of 3.5 degrees. In the centrifugal compressor shown in Fig. 4, the suction face of each diffuser blade 4 comprises a concave spiral portion AB producing compression waves directed towards the impeller 3, the end B corresponding to the last compression wave BA‹ capable of reaching the impeller without being intercepted by the leading edge A‹ of the next blade. As in the previous embodiment, expansion waves are produced at a curved portion BC of the suction face of each blade 4, the portion BC being curved through 7 degrees and preferably terminating at the place where an oblique shock wave starting from A ‹ reaches the suction face. The remainder of the suction face is straight. The pressure face of each blade 4 may be convex, with an initial straight portion. Subsonic diffusion occurs downstream of the normal shock wave D ‹, and guide blades 5 may be provided.
