Filed: 1971-08-04
Abstract: 1331385 Thermal regenerators NISSAN MOTOR CO Ltd 4 Aug 1971 [27 Oct 1970 28 Oct 1970] 36703/71 Heading F4K A rotary regenerative disc type matrix 10 is rotated by a drive arrangement comprising an annular ring gear 12 which is coupled to the regenerator matrix 10 by means of a plurality of equally spaced leaf springs 16. As shown, the ends 16a, 16b of each leaf spring are received in grooves defined by a T-shaped pad 15 disposed in a recess 12b formed in the ring gear, the intermediate portion 16c of the spring being received in an aligned arcuate recess in the outer rim of the matrix 10. The ring gear meshes with and is driven by suitable toothed driving means 13 which may be a pinion gear or a chain sprocket. In a simplified embodiment (Figs. 1 and 2, not shown), the T-shaped pad is omitted and the end portions of each leaf spring (14) are embedded in the inner peripheral wall of the ring gear at locations adjoining the recesses (12a) therein.

Abstract: 1,029,856. Labels and their securing. W. H. BRADY CO. Sept. 18. 1963 [Oct. 17, 1962], No. 36749/63. Heading B8F. [Also in Division G2] Adhesive, liquid-bearing labels are produced by photographing the legend on a photographic stripping film, bringing the stripping film into contact with an adhesive layer on a backing strip, separating the film base from the film-tobacking laminate and cutting the film-tobacking laminate. In the embodiment, a set of adhesive labels is formed by repeatedly photographing a counter registering different numbers on a photographic stripping film, passing the film on rolls 39, Fig. 4, between rollers 41, 42 into superposition with an adhesive bearing backing sheet 35 to form a composite roll 50, unrolling the composite roll 50 (Fig. 6) and stripping the base of the film 28 off in known manner on to a spool 56, cutting, with a stamp 57, 58 through the photographic emulsion and adhesive layer 37 in the position of the counter images, stripping the non- imaged emulsion and adhesive layers off on to a spool 61, having a backing sheet 35 with releasable adhesive labels 62 thereon, which is wound on a spool 63. The backing sheet may be cut in strips. The photographic emulsion may be coated with an opaque, e.g. metallic, layer before being transferred to the backing sheet 35. Further, the emulsion may be coated with a transparent, protective layer after it has been transferred to the backing sheet and had the base stripped. The counter may be surrounded by a frame bearing an inscription which is the same for each of a set of labels and is photographed with the counter.

Abstract: 1418495 Fuel elements UNITED KINGDOM ATOMIC ENERGY AUTHORITY 27 July 1973 [7 Aug 1972] 36814/72 Heading G6C A fuel assembly comprises a plurality of spaced, parallel fuel pins 2 enclosed within a tubular casing 1 having a tubular spike 11 extending from its lower end for locating the assembly in a reactor core support structure 29, the spike 11 being rendered elastically extendable by means of a series of part circumferential slots 17 in a tubular body part 13. Above the body part 13, the spike 11 comprises an end adaptor 12 while below the body part 13 it comprises a nose piece 14. The end adaptor 12 is connected to a ring 10 at the lower end of the casing 1 by means of screws 15. The fuel assembly is mounted by inserting the spike 11 through apertures 25, 26 in upper and lower plates 27, 28 forming the core support structure 29. The end adaptor 12 and the nose piece 14 have cylindrical stellited surfaces 16, 24 respectively which engage in the apertures 25, 26 respectively, and the casing 1 rests on the upper plate 27. The fuel assembly is then rotated to drive bayonet lugs 31 of the nose piece 14 over cam surfaces (33) (Fig 2, not shown) of bosses 32 in a closed sleeve 30 fitted below the lower plate 28 until the lugs 31 engage with recesses (34) in the bosses 32. This causes extension of the central tubular body part 13 of the spike 11 so that an end loading is applied between the lower end of the casing 1 and the upper plate 27. The fuel assembly is thus rendered self-stabilized against random vibrations induced by coolant flow through the fuel assembly. A coolant gag assembly 19 inside the end adaptor 12 of the spike 11 comprises a series of toroidal rings 20 covered with wire mesh discs 21, the rings fitting in longitudinally spaced annular grooves 22 inside a sleeve 23 which fits inside the end adaptor 12.

Abstract: A painting-mask for a sub-assembly is made by applying a substantially unsolvated plastisol or organosol to a solid master mould to form an enveloping coating thereon, fusing the coating on the mould, stripping it therefrom and removing reverse portions, i.e. those which overlie surfaces which will be hidden or invisible when the subassembly is in its assembled position.  The plastisols or organosols may be those based on polyvinyl chloride homopolymer, or copolymer which may, however, be wholly or partially replaced by polyethylene, and application is preferably by dipping the mould, pre-heated to above the gelation temperature of the plastisol, in the latter.  Brushing and spraying may also be used.  In use, the mask, produced as above, is emplaced over a pre-treated sub-assembly which has been incorporated in an assembly to be painted, and a primer or top-coat, or both, applied to the assembly and dried and/or stoved, after which the mask is removed for re-use.

As shown, Fig. 2b, valve 31 has received a control pulse and is maintained conducting by a smoothing inductance (not shown) on the D.C. output side and valves 32, 36 on the lower half of the bridge receive turn ON pulses. Valve 32 is likewise maintained conducting by the smoothing inductor (not shown). Thus valves 31, 32 conduct simultaneously and act as a shunt valve so that by-pass switch 7 can be closed and the converter 30 can then be withdrawn on both the A.C. and D.C. sides, for testing. Depending upon the moment within the A.C. cycle at which blocking is effected, either the valves 31, 32 or 33, 34, or 35, 36 act as shunt valve. Preferably it is arranged for blocking to be applied at a predetermined instant in a cycle so that the same two valves always act as shunt valve and as such are selected to have a higher rating than the others.
