Abstract: 364,808. Pens. KENT, A. F. S., Holm Ray, Iron Acton, near Bristol. Dec. 18, 1930, No. 38136. [Class 146 (iii).] A nib or style for use in ordinary penholders or in reservoir pens consists of three or more metal strips rigidly bound together to form a brush-like implement, the point being ground and polished to a hemispherical shape. The spaces between the strips form channels for the inkfeed. The strips are shown in Figs. 1 and 2 as wires b, the spaces k forming ink passages. In the mounting shown the strips bare bound together by a collar e, against which bears a helical spring g, so that the point can move longitudinally in its mounting. In the modification shown in Fig. 5 the device is in the form of a hollow cylinder l split longitudinally from one end at l<1> into three or more strips b ; the strips are tapered and bent together to form a smooth hemispherical point. In this case the feed may be through a channel formed by a fold in the cylinder, or through the bore k of the cylinder. The device shown in Fig. 7 is in the form of an ordinary nib with one or more wings b folded over to obtain the required hemispherical point. The point-protecting cap may contain a rubber or other cleaning pad.

Title: Nuclear fuel assembly
Inventor: MEFFORD CARL RAYFORD
IPC: G21C3/324
Filed: 1970-08-14
Abstract: 1,256,198. Fuel elements. GENERAL ELECTRIC CO. 14 Aug., 1970 [15 Aug., 1969], No.39415/70. Heading G6C. A nuclear fuel assembly comprises a plurality of fuel rods in spaced array between upper and lower tie plates, a removable open-ended tubular flow channel surrounding the array and adapted to fit adjacent a peripheral surface of one of the tie plates, and restraining means attached to this tie plate for restraining lateral movement of the flow channel away from the tie plate. As shown in Fig. 3a, flow channel 36 is a sliding fit over a lower tie plate 27 formed with a nose piece 17 having openings 39 to receive pressurized coolant which flows upward among the fuel rods 26. To avoid stagnation of the coolant in the spaces between fuel assemblies mounted in a reactor core, a portion (of the order of 5 to 6%) of the coolant is allowed to leak into these spaces from between the tie plate 27 and the flow channel 36. (Coolant may also leak through passages 48 in the tie plate 27 and/or through passages 49 in the flow channel 36). Leakage is controlled by limiting the deflection of the flow channel 36 away from the tie plate 27, by means of a sleeve 40 which abuts an inner shoulder 41 formed on the tie plate and is welded, as at 42, to an outer shoulder 43. The sleeve 40 and the peripheral surface 44 of the tie plate 27 thus form a longitudinally opening slot for receiving the lower portion of the flow channel 36. The leakage flow path is thus substantially lengthened, increasing the leakage flow resistance, and the sleeve 40 substantially prevents the deflection of the flow channel 36 away from the tie plate 27. In a modified version the sleeve 40 is formed with corrugations to increase the leakage flow resistance and increase the rigidity of the sleeve. In a second embodiment (Fig. 4, not shown) the lower tie plate is fitted with a series of headed studs for engaging a corresponding series of longitudinal open-ended slots in the lower end of the flow channel. In a third embodiment (Fig. 5, not shown) a longitudinally opening groove or seat formed in the lower tie plate receives the lower end of the flow channel. Since the groove or seat is relatively shallow, a retainer spring arrangement is provided for urging the flow channel into engagement with the channel retainer seat.

Abstract: 1,056,000. Axle-bearing guides. MIDLAND-ROSS CORPORATION. Oct. 9, 1963 [Sept- 3, 1963], No. 39836/63. Heading B7L. A railway vehicle axle guide assembly comprises a hollow pedestal frame 10, Fig. 4, securable to the rail vehicle body frame (not shown), and having downwardly-extending hollow longitudinally spaced guide columns 13 for a housing 25 of the bearing 29, which housing is part of a saddle 26 supporting the pedestal through fore-and-aft spring pairs 110, the housing 25 being snubbed for vertical and transverse movement relative to the pedestal by friction wedges or shoes 37 under the urge of springs 43 and tiltable about a horizontal longitudinal axis of the pedestal to facilitate increased transverse play. Referring to Figs. 5 and 6, the pedestal has hollow portions extending fore-and-aft of the central housing receiving aperture and each portion has vertically extending wear surfaces 101 whilst the hollow inverted T-shaped saddle 26 has vertical surfaces 95, 96, Fig. 8, on flanges 87, 88 at the ends of the transverse housing walls 77, the surfaces 95, 96 of each flange being engageable with a wear surface 101 and forming a fulcrum edge 97 at the junction of the surfaces 95, 96. The axle bearing 29 is held in the housing 25 between a transversely crowned adaptor 30, having vertical recesses co-operating with retaining lugs 81 on the housing 25, and a block 85 secured to the bottom of the housing by a bolt 86. Referring to Figs. 8 and 9, when axle 3, its bearing 29 and the adaptor are moved transversely relative to the pedestal, e.g. to the left, the adaptor engages the lugs 81 of the housing 25 and thus the upper portion of the saddle 26 moves to the left until the right-hand flange surfaces 95 engage the righthand pedestal surfaces 101 at their lower portions. If there is any further transverse movement the saddle 26 fulcrums on the righthand edges 97, whereafter the contiguous surfaces 96 commence to engage the wear surfaces 101 at their upper portions so as to tilt the saddle as shown in Fig. 9. The assembly is self-centring under the action of the springs 110. Vertical separation of the saddle 26 from the pedestal from 10 is prevented by tie bolts 115 which are each under the bias of a lightweight spring 119. As shown, at the left-hand side of Fig. 4, the load springs 110 may comprise pairs of concentric springs 111, 112.

Abstract: 1491273 Transferring articles from and between conveyers RHEON AUTOMATIC MACHINERY CO Ltd 29 Sept 1975 [30 Sept 1974 10 Feb 1975] 39847/75 Heading B8A A whole row at a time of confectionery articles, bread &c. F are transferred from a conveyer 308 on to a conveyer 361 (or as shown, trays 364 thereon) by the conveyer 308 being first bodily lowered and then moved laterally through a closed-loop path back to its normal position. Up-and-down movement of the conveyer 308 results from the action of a cam 341 acting via a follower 345 and linkage 347 (Fig. 12) 349, 355, 357, on a rod 302 which carries a drive roller 328 of the conveyer at its lower end. The drive to roller 328 operates from a motor 334, bevel gearing 322, 320, and splines 318 on the rod 302. Lateral movement of the conveyer results from a crank 313 (the end only, of which can be seen in Fig. 9, as the crank is in a position at right angles to the plane of the figure) driven by a drive shaft 314. The crank 313 at its other end carries a first cam follower 331 which engages a cam slot 311 in a housing mounting the rod 302. The crank 313 is radially extensible against spring action as governed by a second cam follower 333 which bears on a fixed cam 326 of generally circular configuration. In a modification (Figs. 7 and 8, (not shown), the cam 341 is dispensed with, and mechanism similar to the crank 313 and cam follower 331, generates both lateral and up and down movement of the conveyer 308.
