Title: Fuel bundles in heavy water and light water nuclear reactors
IPC: G21C3/328
Filed: 1976-11-19
Abstract: 1528267 Fuel elements INSTITUTE OF NUCLEAR ENERGY RESEARCH ATOMIC ENERGY COUNCIL 19 Nov 1976 48312/76 Heading G6C A fuel element for use with a water-moderated nuclear reactor comprises a bundle of fuel rods and at least one Be-containing rod. The Be may be present as element or compound, and acts not only as neutron moderator but also as fast neutron multiplier. The use of such fuel elements serves to reduce the D 2 O inventory in heavy water reactors or to reduce the necessary U-235 enrichment in light water reactors. In one embodiment, Fig. 2, a typical CANDU 19-rod fuel element has the central rod replaced by a Zircaloy-2 sheathed Be rod of the same size. The same reactivity is obtained with this modified fuel element but with a reduction in lattice pitch equivalent to a swing of 9% in the D 2 O moderator inventory, when used in a pressurized heavy water reactor, or a swing of 16À5% in the D 2 O moderator inventory, when used in a boiling light water reactor. Both these reactors are of the CANDU type, viz. the Douglas Point and Gentilly reactors respectively. In a further embodiment, Fig. 5, a CANDU 28-pin fuel element has twelve additional Be rods inserted in the interstitial positions shown. When used in a CANDU heavy water reactor, viz. the Pickering reactor, a saving of 9À78% of the D 2 O moderator inventory can be achieved.  In another embodiment (Fig. 7, not shown), a 19-pin fuel element with 1À95 w./o. U-235 enrichment has six smaller Be rods inserted into the bundle, resulting in a possible reduction of 0À1 w./o. in the enrichment while still yielding the same neutron multiplication factor.

Abstract: 1,095,154. Building pneumatic tyres. PIRELLI S.p.A. Dec. 2, 1964 [Dec. 3, 1963], No. 48917/64. Heading B7C. A method of building a pneumatic tyre comprises the steps of applying sidewalls 76 to a carcass 74 built on a rigid expansible drum (preferably as disclosed in Specification 770,884) while it is still on the rigid drum, transferring the pocket so formed to a shaping drum including a flexible diaphragm 66 held between axially reciprocable end plates, mutually approaching caps 33, 34 having cylindrical surfaces (35, 36) (see also Fig. 7, not shown) for positioning a breaker 77 and tread 78, and stitching them on to the carcass and sidewalls whilst in position on the deformed diaphragm. The tread may be stitched directly on to the carcass and sidewalls or, as shown, non-adherent strips, e.g. of polythene, may be applied on the carcass before application of the sidewalls, the sidewalls turned back before the carcass has been fully shaped by the diaphragm, and the strips removed. The tread in this case is stitched directly on to the carcass and the sidewalls are then folded back over the carcass and tread. When the tyre carcass has indeformable bead rings the plate 42 may comprise a plate (42<SP>1</SP>) and detachable rings (80) (Fig. 11, not shown).

Abstract: 1357655 Optical elements for cameras POLAROID CORP 22 Oct 1971 [22 Oct 1970] 49251/71 Addition to 1292239 Headings G2A and G2J In the camera of the parent Specification 1292239 the viewing surface 64 is replaced by the viewing surface 60 shown in Fig. 4 which is an essentially planar surface comprising a plurality of discrete reflective surfaces which provide an approximation of an ellipsoidal reflecting surface. The camera of Fig. 1, as in the parent Specification, can be made to assume either a focusing mode or an exposure mode. Fig. 1 shows the focusing mode, in which light entering through the lens system 6 is reflected from a specular mirror 40 and a further mirror surface 42 to a viewing section 22. The light path may be regarded as originating at an apparent entrance pupil at 56. The plate 44 carrying the reflective surface is shown in more detail in Fig. 4, the surface comprising a large number of minute indentations 60, some of which are shown in magnified form at 102. Each indentation is a facet having a particular orientation depending on the relative positions of the point light source 104 and the image point 108. The facets are essentially planar but may have a slight curvature. Plural light rays 106 emanating form source 104 are reflected and converge at point 108, which corresponds to the exit pupil 59. It is stated that this arrangement provides an essentially planar approximation to an ellipsoidal reflecting surface which avoids the coma and astigmatism effects introduced by such reflecting arrangements as those of Figs. (not shown) 2 and 3.

Inventor: HUSY HANS
Filed: 1963-12-13
Abstract: The invention comprises a process for dyeing cellulosic/polyester mixtures in which the mixture is dyed at temperatures above 100 DEG C using reactive dyes for the cellulose and disperse dyes for the polyester, all of these dyes being stable in aqueous solutions at 110-140 DEG C at pH values measured at 20 DEG C of at least 8.5, there being present in the dyebath a neutral salt and not more than 5 grams per litre of a basic fixing agent.  The dyeing is preferably carried out at 120-130 DEG C.  The reactive dyes used contain a substituent whereby the dye is capable of forming a chemical linkage with the substrate, e.g. a halogen atom or a group -O-SO3H, and may contain a di-or trichloropyrimidyl group or dichloropyrimidyl methylene group bound to the dye by an oxygen or sulphur atom, or by an unsubstituted or monosubstituted imino group, or the dyes contain a group bound to the dye by an oxygen or sulphur atom or a substituted or unsubstituted imino group, of formula. <FORM:1070928/D1-D2/1> in which y is an oxygen or sulphur atom, or a substituted or unsubstituted imino group, hal is a chlorine or bromine atom, and 2 is hydrogen or a substituted or unsubstituted alkyl, cycloalkyl, aryl or aralkyl group, or contain a b -chloropropionyl, b -sulphatopropionyl, or acrylyl group.  The disperse dyes may be azo, anthraquinone, nitro, styryl or pthaloquinone dyes.  The neutral salts are sodium chloride and sulphate, the basic fixing agent may be any alkali having a pH of at least 8.5 at 20 DEG C in dilute solution e.g. sodium, potassium and lithium hydroxides, potassium and sodium carbonates and bicarbonates, trisodium phosphate or potassium and sodium silicates.  The dyeings are carried out by entering the material into the dyebath at low temperatures, e.g. 40 DEG C raising slowly to the dyeing temperature which is maintained for the required period and then allowing to cool, followed by rinsing and soaping, dyeings are effected until exhaustion of the bath occurs. The cellulosic material may be natural or regenerated.

In this way the seat belt may be adjusted for use to a wearer and a further initial slight withdrawal will allow the pawl 41 to engage the spool ratchet preventing retraction and thus relieving the wearer of the constant tension of the retraction spring. The brake disc 31 is provided with a lug 53 which engages in a slot 54 in the frame 12 to limit rotation of the disc 31 and a spring washer (not shown) is provided between the discs 30, 31. The retractor is also provided with an inertion sensitive mechanism in the form of a circular pendulum 16 which on tilting raises a pivoted catch plate 19 until pawl 20 thereon engages a primary ratchet 21 on the spool the ratchet 21 being of resiliently defoamable plastics material allowing limited movement. The catch plate 19 also rocks a bar 23 to engage ratchet teeth 24 on the spool end plates. Alternatively the retractor may be provided with a mechanism sensitive to the speed of belt withdrawal from the spool 13.
