Abstract: 950,896. Detecting neutrons. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Nov. 8,1962 [Nov. 17, 1961], No. 41217/61. Heading G6P. A neutron flux monitor comprises two elements which are of similar dimensions and densities but of materials of different neutron sensitivity so as to constitute a detecting element and a reference element, a capsule surrounding the elements to provide a uniform thermal environment for both elements, and a thermocouple for indicating any temperature differential between the two elements. In the drawing two dimensionally identical collars 11, 12 are carried by an alumina rod 13 and mounted in a stainless steel capsule 22 divided into two compartments by a stainless steel disc 14 which acts as a shield to prevent thermal or charged particle radiation passing between the two collars. Collar 11 is of a boron/ aluminium alloy and is heated more by neutrons than by aluminium collar 12, the heating effect of other radiation being substantially the same for both collars. The temperature difference between the two collars is measured by two thermocouples 17,19 connected in series to leads 16 which pass through bores in the rod 13 to bores in the top of the capsule. The capsule is suspended by a wire 27 and may be lowered into a nuclear reactor. The detecting element could contain lithium, cadmium, or nitrogen instead of boron, or, for detecting fast neutrons, could contain beryllium.

Title: Improvements in or relating to the manufacture of flat glass
IPC: C03B18/04
Filed: 1962-11-20
Abstract: <PICT:1074314/C1/1> A method of manufacturing flat glass in ribbon form comprises advancing two layers of glass in ribbon form towards one another along the surface of a molten metal bath, bringing said layers in ribbon form together at a confluence where the layers coalesce, and drawing a ribbon of glass upwardly from said confluence. Molten glass at a controlled rate is fed from two spouts on to the surface of a bath of molten metal 1 (e.g. tin or tin alloy) under such thermal conditions as to allow unhindered lateral flow of the molten glass which is then advanced as two buoyant layers moving towards each other. These two layers are cooled until they are sufficiently viscous to be raised from the bath 1. The two layers may join before being raised from the bath, though preferably they are bent away from the bath 1 to a confluence 36 where they coalesce and from where a ribbon of glass is drawn upwardly.  The temperature of the bath and of the glass ribbons is controlled by regulators 32, 33. A plenum of protective inert atmosphere is maintained above the molten metal tank, within the vertical drawing chamber 38-40, and also by means 47 underneath the two ribbon layers where they are raised about the molten metal bath.  The ribbons are gripped at their edges by rollers 57, 58 in the bath which control the width thereof and then passed upwards through the drawing chambers between heaters 54, 55 through an outlet 43 into the annealing lehr 44.  The outlet 43 may be sealed with a protective gas by using a laminar flow as described in Specification 1,017,752. Also the molten metal in the bath may be constantly recirculated in the manner described in Specification 966,709.
