Title: Improvements in or relating to Nuclear Reactors.
Inventor: PARAVICINI THOMAS PITT DE
IPC: G21C15/24
Filed: 1965-11-29
Abstract: 1,161,883. Nuclear power plant. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 30 Nov., 1966 [29 Nov., 1965], No. 50549/65. Heading G6C. In a nuclear reactor power plant, low-pressure steam generated in the core is divided into two streams, one of which is supplied directly to a low-pressure turbine while the second is applied to a heat exchanger which supplies hightemperature high-pressure steam to a highpressure turbine. The exhaust from the highpressure turbine is returned to the core while that from the low-pressure turbine is condensed, re-pressurized, and then fed to the heat exchanger for the high-temperature cycle. Jet pumps circulate the steam over the heat exchanger.

Title: Lapping head
IPC: B65H81/08
Filed: 1972-11-06
Abstract: 1369523 Lapping heads STANDARD TELEPHONES & CABLES Ltd 6 Nov 1972 51033/72 Heading B8G A lapping head of the kind in which a moving core passes through a roll of tape is characterized in that (a) the radially innermost end of the tape from the roll is initially connected to the core and the roll is then rotated to wind the tape on to the core; and (b) the head comprises an outer annular member 4 to which the outermost turn of the roll is connected, the member 4 being frictionally driven by an inner annular member 2 carrying the roll of tape. The friction coupling is reduced in response to increased tension as a means of tension control. In Fig. 1 the roll of tape is carried by roller members 9 on the inner annular member 2 and the outermost turn of the roll is connected to a drum 5 on the outer annular member 4. A driving plate 1 is coupled rigidly to the annular member 2 and turns it to cause rollers 9 on the plate 2 to unwind the innermost turns from the tape pad. A clutch or brake mechanism (not shown in Fig. 1) normally interconnects the plate 2 and the drum 5 but when the tension in the unwound tape rises such tension deflects the roller 9 around which the tape passes to disengage or reduce the effect of the clutch or brake mechanism and so cause "slack" tape to be generated in the outer turns of the tape. The turns of the tape then move over one another so that the "slack" generated is effectively moved to the inner edge of the pad and so to the region of the core being lapped. Also attached to the roller plate 2 is at least one guide arm 12 over which the tape passes just before being wound on to the core. This guide arm is housed in a ball-and-socket joint such that it can be set to any desired inclination, there being means (17, 18), Fig. 6 (not shown), for locking the ball-and-socket joint in any desired setting. The drum 5 may have vane-like flanges to create frictional forces with the surrounding air. Alternatively a spring-loaded brake pad (not shown) may engage the drum 5 when the aforesaid clutch is disengaged.

A double-walled metal pipe section for connection with similar sections to form a flue pipe comprises substantially concentric inner and outer walls 11 and 12 respectively, the walls being connected together at one end thereof to form a male element 13 whilst the other ends of the walls are open to form an annular female element 14 adapted to receive the male element 13 of a like section. The outer wall 12 is provided with a pair of circumferential grooves 13a and 14a which respectively define the extent of the male and female elements 13 and 14 and also maintain the concentricity of walls 11 and 12. In a preferred embodiment the male element 13 includes an inner wall portion 11a of larger diameter than that of the remaining inner wall portion 11 and female element 14 includes an outer wall portion 12a of larger diameter than that of the remaining outer wall portion 12, thereby permitting mating of male element 13 with a female element 14, with inner wall portion 11a forming an abutment surface accommodating free expansion and contraction of the inner wall of an adjacent pipe section. Male element 13 includes a surface 11b of larger diameter than that of 11a, and connected to it by an inclined guide surface 11c, to facilitate formation of the pipe joint. A further inclined wall portion 11d brings inner wall 11 into contact with outer wall 12, the walls being folded radially inwardly to lock them together.

Title: Refractory compositions
Inventor: WILSON ROGER EARL

Filed: 1965-12-23
Abstract: A method of making a refractory composition for subsequent firing comprises mixing dead-burned basic refractory particles, e.g. dolomite and/or magnesia, with a carbonaceous material capable of undergoing pyrolytic decomposition during firing to form a carbon bond, e.g. coal tar, coal tar pitch, or bituminous asphalt, and incorporating in the mixture non-crystalline powdered carbon.  This carbon may be a carbon black or powdered coal or coke, and a blend of a high oil absorbing black with a thermal black is mentioned.  In an example, the dead burned particles are mixed with 0.5 to 10% (based on the weight of the total mix) of carbon black, the mixture heated to 225 DEG  to 325 DEG  F. and then 4 to 10% (based on the total weight) of coal tar pitch added.  Specific examples are described.
