Abstract: 1,021,084. Reactors. ENGLISH ELECTRIC CO. Ltd. Aug. 23, 1963 [Aug. 28, 1962], No. 32992/62. Heading G6C. [Also in Division B3]  A reactor fuel element string contains at least one fuel element which is provided with an electrical lead forming part of a temperature-sensitive equipment (such as a thermocouple), the lead or leads passing along the fuel element string for connection to other parts of the equipment, wherein each fuel element having a lead has a cutting device fitted to it for cutting the lead when the lead is withdrawn from the fuel element. The fuel element can 1Oa has longitudinal fins 106 interconnected by bracing members 14. A thermocouple 12 is attached to the can and its lead 15 passes through a cutter 20 (Fig. 2). A loop 15a has to be withdrawn by pulling the lead before the lead contacts and is cut by a cutting edge 17a, the lead being clamped in the cutter guide channel so as to prevent further withdrawal of the lead after the loop 15a has been taken up. Further loops as at 22 may be provided to accommodate expansion of the fuel elements. Other forms of cutter are described, all utilizing a fixed cutter and clamping of the lead. Where a number of fuel elements in a string have thermocouple leads, the loops 15a associated with the cutter on each fuel element are made of different sizes so as to be severable singly or in pairs in succession as all the leads are simultaneously withdrawn, so as to reduce loading on the withdrawal winch.

Abstract: 873,084. Boiler furnaces. BABCOCK & WILCOX Ltd. Nov. 1, 1957 [Nov. 1, 1956], No. 33366/56. Class 51 (1). [Also in Group XIII] In a furnace wall comprising a row of spaced vapour generating tubes 1, Figs. 1, 2, 4, fronted by a similar row of superheater tubes 5, the latter are positioned relative to the former by means which project rearwardly from the superheater tubes into the spaces between the generating tubes. At positions in the wall where the tubes 5 pass through the tubes 1 to connect with distributers such as 6, the gas sealing webs 2 spanning the tubes 1 are omitted and the tubes 1 are arranged in threes such that three suitably bent tubes 5 may be passed through the gaps formed. Gas-tightness around the distributer 6 is ensured by cowling 7, 8. The positioning-means may comprise a bar 20, Fig. 5a, welded to adjacent tubes 1 interengaging a member 21 welded to the tube 5. Alternatively a socket 22, Fig. 5b, welded to the tube 5, may be used with a member 23 welded to a web 2. Welded L-shaped members 26, 27, Fig. 7a, may be employed and in a modification of this arrangement the member 26 may be free to move between the web 2 and the adjacent tubes 1, the side faces of the member being diverged for this purpose. Two further arrangements are described of means solely welded to the tubes 5-in one, crossed-members engage in the triangular space between the web 2 and its associated tubes 1 whilst in the other, the side faces of a rectangular member 31, Fig. 10a, are diverged to engage in the space. In cases where sinuous superheater tubes are used the positioning means either comprise pins welded at each end to a tube 5 and associated web 2, respectively, or pins welded to tubes 5 and secured in key-hole slots, such as 36, Fig. 9c, in the webs 2, caps 35 being welded over the pin heads and slots to ensure gas-tightness. In walls having slidable means such as 31, or the cross-members &c., the location of the tubes 5 may be accomplished by bending one or both tubes 1, Fig. 11, at suitable places 41 so that the means 31 &c. may be pushed rearwardly into the space between the tubes 1 before allowing the tubes 5 to drop into positions where the means are located and held behind the tubes 1. Specification 873,085 is referred to.

Abstract: 995,626. Knitting. A.PLANCK. Sept. 18, 1961 [Sept.17, 1960], No. 33404/61. Headings D1C and D1K. In producing knitwear on a two-bed, e.g. cylinder and dial, circular knitting machine, knitting on one bed in respect of a portion of the knitwear is discontinued in one revolution of the machine in N operations (N > 1 e.g. 2) in which 1/N of the loops concerned are transferred during each operation. A double welt, made by knitting one layer on each needle bed, is completed by two operations, firstly the loops on needles 1, 3, 5. . . 19, Fig. 1 bed 2 are transferred to the corresponding needles of bed R and then the loops on needles 2, 4, 6... 20 of bed Z are transferred to their corresponding of bed R. Fabric may be produced having stripes C<SP>1</SP>, C<SP>2</SP> and F<SP>1</SP>, F<SP>2</SP>, F<SP>3</SP> of ribbing and areas B of plain knitting, the transition from ribbing to plain knitting taking place as described in relation to the double welt. The selection of transfer needles may be effected by providing long and short needles, needles with long and short butts, pattern wheels or jacquard attachments. As shown, a cylinder and dial knitting machine has transfer cam boxes T 1 , T 2  with tracks K 1 , K 2  to engage, the butts N 1  of needle jacks N which have not been turned inwardly by a pattern drum M and thus to lift the jacks and hence the needles into their transfer position.

Abstract: 899,783. Rotary printing machines. NEBIOLO S.p.A. Sept. 29, 1960 [Oct. 3, 1959], No. 33499/60. Class 100(2) In a sheet-fed rotary offset multicplour machine wherein sheets are fed by oscillating grippers from a feedboard and through two or more printing couples associated with transfer cylinders, there is a central control lever system adapted, during the operation of the machine, for effecting small radial displacements of the stops in the gripper systems of the oscillating grippers, and the grippers on the transfer cylinders. These adjustments enable the machine to be rapidly pre-set for printing sheets of varying thickness. As shown, sheets taken from a pile 3, Fig. 1, and placed on a feedboard 5, are conveyed therefrom by oscillating grippers 7 to the grippers on an impression cylinder 6 in the printing unit 1, then transferred by the grippers of transfer cylinders 11, 12, and 13 to the grippers of an impression cylinder 14 in the second printing unit 2. The printed sheets are then taken by grippers on a chain 17 and deposited on a pile 18. The gripper stops or pads 7a, Fig. 2, are raised or lowered relatively to the feedboard 5 when an eccentric bush 30, which supports the bearing 32 of a shaft 31 carrying the stops, is rotated by the movement of a rod 19 which is pivoted to a lever 29 secured to a pivot 29a. The pivot 29a is secured eccentrically to a bush 25 which can be rotated about the axes of the pivot 29a by a worm and wormwheel device (Fig. 3, not shown) operated by a hand wheel. A lever 24, secured to the bush 25, is connected by a rod 20 to a cam 22 freely mounted on the transfer cylinder 11. When the bush 25 is rotated, the cam 22 is also rotated to adjust the gripper stops 33 on the cylinder 11, by rocking a pivoted lever 35 which carries a shaft 34 on which the stops are mounted in the cylinder. The lever 35 has a roller 39 at its free end which is engaged by a roller 40 on a two-armed lever 41 pivoted on the cylinder 11, and the other end of the lever 41 has a roller 43 which is engaged by the cam 22. Thus the cam 22 rocks the lever 41, which in turn rocks the lever 35 and adjusts the gripper stops radially. Rotation of the cam 22 is transmitted through a rod 21 to a further cam 45 on the transfer cylinder 13 to adjust the gripper stops therein. Further rods may be similarly arranged to adjust cams on other transfer cylinders. Thus, when the bush 25 is rotated by its hand wheel, all the gripper stops on the transfer cylinders, and those of the oscillating grippers on the feedboard are adjusted. The hand wheel for the bush 25 may be associated with a pointer and a scale graduated to relate to sheet thickness.

Abstract: 521,073. Protective cut-out systems. WHIPP & BOURNE, Ltd., and WHIPP, F. Nov. 18, 1938, Nos. 33506/38 and 5979/39. [Class 38 (v)] Time - grading of the release of circuit-breakers controlling main and subsidiary circuits of a d.c. distribution system, is effected by varying the rate of decay of the flux linking the holding-coils when the latter are de-energized on fault, the rate of decay being most rapid for the breakers furthest from the source and slowest for those nearest the source. In the Figure, the de-energization is effected by shortcircuiting the holding-coil 20 at contacts 27 which are closed on voltage-drop due to a fault, the coil being connected across the mains 21, 22 as in Specification 214,667, [Class 38 (v)]. The resistance 24 which is included in the shunt circuit ensures a rapid decay as in the case of a remote breaker, but the next breaker towards the source has only a part of the resistance 24 in the shunt circuit, whereas that of the breaker next the source is directly across the coil 20, so providing a minimum rate of decay. In a modification, Fig. 6 (not shown), the trip contacts are in series with the holding-coils and windings inductively related to the latter have in series with them graded amounts of resistance. The latter arrangement may be modified, according to one Provisional Specification, by shrouding the coils 20 with copper tubes of different inductance values.

A door fastening of the link latch type comprises a pivotally mounted latch piece 6 and a keeper 1 with which the latch piece engages, and embodies a spring loaded toggle linkage which is extended when the latch piece is in the latched position and retains the latch piece in that position, release means arranged to collapse the toggle linkage to release the fastening, and a trip lever pivotally mounted intermediate its ends and having its outer end arranged for engagement with the keeper as a result of door closure to cause the inner end of the lever to act directly on the linkage to trip the fastening. In the unlatched position, Fig. 1, of a fastening, a toggle linkage formed by a link 19 and a lever 13, pivoted at 14, is retained in its extended position by a spring urged rod 26. Downward movement of the keeper 1 rotates a trip lever 30 about its pivot 24 to collapse the toggle linkage 19, 13 by shifting its pivot point 18 overcentre. A second toggle linkage composed of the link 19 and a link 22 is thus extended and the latch 6 is rotated about its pivot 24 by a link 15 to retain the keeper in its latched position. Unlatching is performed by moving the rod 26 to the left by a suitable handle to collapse the toggle linkage 19, 22. The fastener of Fig. 3 is similar, but is unlatched by rotational movement of a rod 37 clockwise from the position shown to collapse a toggle linkage formed by a link 33, pivoted at 35 to the latch piece 6, and a lever 36, and to thus allow the latch piece 6 to rotate free the keeper 1. The latch piece 6 is retained in its unlatched position by a second toggle linkage formed by the link 33 and the latch piece 6, a tension spring 38 holding the toggle linkage in its extended position as it did with the first toggle linkage. Movement of the keeper towards the latched position rotates a trip lever 49, pivoted at 41 to the latch piece and having a cut out 40 within which an extension of the pivot 34 can move, to collapse the toggle linkage 6, 33 by shifting the pivot extension upwardly to the position shown.
